Conveyor electric drum basic classification

Currently the classification of electric drum There are four basic ways. That is based on the motor cooling method, using gear transmission structure type, electric drum basic

characteristics of the work environment and the motor is placed outside this drum are several ways to classify the electric drum.

One, in different ways according to the spiral conveyor motor cooling electric drum can be divided into three categories
Air-cooled electric drum
This is characterized by electric drum motor without oil cooling by conduction, radiation, convection and wind, can be divided into two kinds of forced air cooling and natural

cooling.
Oil-cooled electric drum
This electric drum also called indirect gravity conveyor oil-cooled electric drum. Drum motor has a cooling fluid, since the spinning roll body, scraper plate on the cylinder continuously poured

into the oil motor and the gear on the motor and gear away the heat generated during the operation, the heat transfer

The walls of the drum body, accelerate the motor cooling, and gears produce lubrication. Oil-cooled electric drum key is allowed to enter the interior of the motor oil.
Oil-filled electric drum
Oil-filled electric drum, also called direct oil-cooled electric drum, this type of electric drum allows flow into the interior of the motor directly with the motor rotor and

stator windings contact them work the body heat generated by the drum rotates continuously transmitted to the inner wall of the drum. This knot

The cooling structure is better, but the quality of the lubricant and the motor is relatively high requirements.

Second, the structure is divided by gear transmission electric drum type
Many domestic and foreign production reducer type, but can be used in the mass production of electric drum no more than three types.
Fixed axis gear drive electric drum
The most common domestic electric drum unit is fixed shaft gear reducer drive, and gear drive more than 95% fixed axis involute cylindrical gear transmission structure. These

transmissions orange simple structure, reliable performance, easy to manufacture, easy installation and maintenance, but also has high efficiency, low noise

Advantages. Top two deceleration, a few three deceleration.
OK amount of electric drum gear
The drive shaft geared form and relatively fixed, with small size, light weight, carrying capacity, smooth operation, etc., but the maintenance is not convenient, electric drum

abroad this common structure type.
Cycloid drive electric drum
This structure type described as "Chinese characteristics", except Japan, other countries rarely use this transmission structure, with cycloid structure of this drive small

electric drum can achieve great speed and power.

Third, according to the application environment to electric drum sub-sub
Electric drum of ordinary common application environment, corrosion, and explosive three kinds of occasions. If the subdivision still be hot, humid tropics, and some special

occasions, but these occasions the small number of electric drum, usually only as a non-standard electric drum production.

Currently there are: TDY75 type oil-cooled electric drum, DY1, JYD type mobile electric drum, YZ-type cycloid electric drum, exterior electric drum, TJ-type oil-immersed

electric drum.

Conveyor classification and Future Trends

Conveyor The conveyor having a traction member generally include traction, bearing components, drive means, tensioning means for redirecting means and the support parts. Tractor

parts used to pass traction, can be used Extendable conveyor, drag chain or rope; Holds material bearing member to have the hopper, bracket, or

Spreader, etc.; drive to the conveyor to power, generally consists of motor, reducer and brake (stopper) and other components; tensioning devices generally have two kinds of

screw and a hammer, can maintain a certain tension pulling element and sag in order to ensure the normal operation of the screw conveyor; support for supporting the retractor

Cited documents or carrying member, can be idlers, rollers, etc.
A conveyor having a traction member structure is characterized by: the material to be transported to the traction member mounted on the bearing member are joined together, or in

directly mounted on the pulling element (such as belt), the pulling element or chain around both of the rollers connected to form load transportation of materials, including

branches and not transported

The material being a non load branch closed loop, continuous motion using the traction member conveying materials.

Such a wide range of conveyors, the main belt conveyors, slat conveyors, trolley conveyors, escalators, moving walkways, scraper conveyor, buried scraper conveyor, bucket

conveyor, bucket elevator , overhead conveyors and overhead lifts and so on.

Conveyor without pulling element different structure and composition, working member for transporting the material is not the same. Their structure is characterized by: the use

of rotational movement of the work member or reciprocating motion, or by the medium flowing in a pipe conveying the material forward. For example, the roller

Conveyor working member of a series of rollers, the roller rotates to transport materials; screw conveyor working member of the spiral, spiral chute rotates in order to push the

material along the trough; vibrating conveyor working member of material groove, trough reciprocated to convey placed

The materials.

Conveyor will be toward the future large-scale development, to expand the scope, automatic sorting of materials, reduce energy consumption, reduce pollution and other aspects of

development.

Large transmission capacity, including large-scale, large single length and large transmission angle and other aspects. The length of the hydraulic conveyor belt has reached

more than 440 km length of nearly 15 km of single, and has appeared composed by a number of Taiwan Contact B two places "belt conveyor path." Not

Chain conveyor working principle characteristics and selection of presentation

Chain conveyor (referred to as "chain transport machine") is combined with the advantages of similar products, transportation equipment generally summarized in the practical

application problems, comprehensive development of a new generation of more comprehensive domestic transportation equipment. The principle of advanced, novel structure

reasonable, energy efficient. Is for

Generation of Flexible skatewheel conveyor is an ideal product. Has been widely used in building materials, chemical, thermal power, food processing, mining, machinery, metallurgy,

transportation, ports, transportation and other industries.
1 Working Principle
Exist between the bulk material particles to the inner friction force and internal pressure, when the conveyor chain Telescopic conveyor movement and accessories, bulk material in the slot

machine by the conveyor and conveyor movement direction tension in the same direction, the bulk particulate material room pressure, within a bulk material so that the friction

force increases. When this

Friction force is larger than the inner bulk material and the friction machine side wall, the bulk material will be moved forward along the direction of conveyor movement, and

increasing the internal pressure of the bulk material layer to ensure a stable state, thus forming the overall continuous flow, like water in general.
2 Typical materials can be transported
Chain conveyor can transport powder, granular, small block materials a thousand species typical are: cement products, cement raw materials, sand, limestone, coal, coke powder,

fly ash, sawdust, crushed ice , powder, urea, synthetic fertilizers, soap powder, baking soda, soda ash, graphite

, Plastic particles, polyethylene, resin, potassium, ammonium sulfide, clay powder, quartz sand, iron ore, crushed slag, salt, starch, wheat, cotton, broken feed, malt sugar,

rice, corn, soybeans.
3 Key Features
(A) conveying capacity: with compared to other types of conveyors, chain conveyors with small size, the advantages of a large transmission capacity, it simply belt conveyor 1/5

of the space or screw conveyor 2/3 of the space can deliver the same flow rate of the material. Transport capacity of 6m [] 3 / h  500m [] 3 / h

.
(2) long service life, the use of low cost: alloy steel, heat-treated by the scientific processing of conveyor chains, their normal life of more than five years, the chain

roller life is not less than one year (the whole machine most wearing parts), thus ensuring a less amount of maintenance, greatly reducing the use of expenses, improve

Production efficiency.
(3) low energy consumption: With the inner friction material, so that most of the work done by moving parts are converted to active power. Greatly reducing the use of chain

conveyor hook material to its resistance to energy consumption is only 30% -60% of the screw conveyor.
(4) seals, security: machine fully sealed so that dust can seamlessly drill, easy to operate, safe, reliable operation.
(5) Process layout flexibility: choose any location in the cabinet to allow multiple types of material inlet and outlet can be elevated, ground or pit arranged horizontally or

climbing (≤ 15 °) installation.
4. Equipment selection
Proper selection and use reasonable care in order to give full play to the best performance of advanced equipment. In the selection of chain conveyors, should pay attention to

the following important parameters:
(A) the choice of chain speed
Users should first according to the performance of the material being transported, the state (abrasive, melt temperature, particle size) and other factors choice.
(2) the choice of models
Chain speed is determined, you can choose the best model based on throughput. Each model has a basic throughput. In the same throughput, select the larger models can reduce

chain speed, thus extending the service life, but also pumping capacity should not be too small, if the actual amount is less than the aircraft transporting more than 30%,

Occurs when using the material layer is too thin, the inner pressure is too small, resulting in idling, but increased wear.
(3) The choice of power
Once the model is selected, according to throughput, transmission length and process layout Conditions Select power and gear reduction ratio and assembly type. Drive power in

45Kw above, it is recommended to use Y series motor + hydraulic coupler + ZSY series reducer. Drive unit assembly type are: left loading

, The right equipment and back-mounted (only applies to power in less than 5.5KW XWD cycloid motor).
(4) the choice of material inlet and outlet
The size of the material inlet and outlet, users need to choose, the choice must be noted:
a. For illiquid or humidity of the material, generally should not be used to make progress spout, so as not to feed poor.
b. arrangement due to process constraints. When the first inlet from the tail shaft closer, generally should not be used motivated discharge.
c. This machine can be used multiple feed ports and a plurality of discharge ports, but can also according to user needs, providing band brake spout.
d. both the upper and lower cross-bridging chain transporting the plane, should the middle section of the bottom were used to spout (a band brake and two without brake) and both

sides of the inlet.

Loader Hydraulic Components & Pressure Monitoring Overview

First, the loader hydraulic components
1 Power Components
Loader hydraulic power units mainly. Pump is to provide pressurized hydraulic fluid to a hydraulic component is a pump, it is steel roller conveyor relying on sealed volume variation principle to

work, it is generally referred to as displacement hydraulic pump. It is the function of the power machine (such as electric motors and

An internal combustion engine, etc.) of the mechanical flexible conveyor energy is converted into a liquid pressure energy. Pump has the following features: having a plurality of sealing a space

and because changes can periodically; absolute pressure of the liquid in the tank must always be equal to or greater than atmospheric pressure; has a corresponding assignment

mechanism.
(2) the control element
Control element is mainly speed control valve, steering servo valve, steering flow control valve, the working hydraulic system control valve and the part of the relief valve,

safety valve and so on.
Relief valve, the pressure relief valve should be according to the liquid movement, and to control the pressure of the liquid, the main performance parameter is the control

pressure. In addition to steering loader relief valve is a pilot operated relief valve, the rest are direct-acting relief valve and safety valve type, adjust the valves are hand

wheel or adjusting screw

Mother.
Directional control valve has a boom cylinder valve and the bucket cylinder valve, used to control the transfer bucket and boom cylinder direction of movement of the hydraulic

cylinder, the bucket and boom can be parked in a position and can control the valve opening degree of the hydraulic cylinder to obtain different speeds. The bucket

Hydraulic cylinder valve is three six-way spool valve, it can control the bucket forward, backward, and in a fixed position in three movements, the boom cylinder is four six-way

valve spool valve, it can control boom rising, falling, fixed and floating four movements. Boom float position allows the load

Machine on flat stacking operation, with the situation on the ground working device can float freely.
Buffer fill valve (double acting valve) is overload valve and non-return valves, mounted in parallel with the bucket hydraulic cylinder back on the road, and its role consists

of three:
When the bucket hydraulic cylinder slide valve in the neutral position, the bucket cylinder chambers were closed after death, such as buckets subject to additional impact load,

causing a sudden rise in local oil pressure will result between the valve and the hydraulic cylinder components , pipeline damage. Set the overload valve that is able to buffer

the hydraulic overload.
The boom lifting process, so that the bucket cylinder automatic drain and fill oil. Loader linkage stopper is provided, when the boom in the lift to a certain position, the

linkage may occur interference phenomenon.
Loader unloading, to achieve rapid weight bucket by the next turn. And homeopathic hit the stopper so that the remaining material hopper unloading the net. When unloading, the

pressure oil into the front chamber of the bucket cylinder to achieve the bucket. The center of gravity over the bucket when the bucket dumplings point, the bucket under the

action of gravity acceleration flipped. But

Fuel pump speed is the speed limit, because the buffer fill oil Yan in the one-way valve in a timely manner prior to the transfer bucket cylinder chamber up the oil, the bucket

can quickly scroll down, hit the stopper, the realization hit the bucket discharge. In order to improve operational efficiency loader, the system uses a double pump confluence,

diversion,

Steering priority unloading system. When the steering, the steering pump to work the system to provide extra oil. Not steering, steering pump fluid through the confluence of all

the one-way valve into the working device system. When working device system pressure reaches the unloading valve set pressure adjustment, steering pump to work wear

Set the oil back into the tank through the unloading valve, allowing hydraulic mechanical transmission provides greater Digging force. Rational use of the engine power, improve

the overall operational efficiency.
3 actuators
Mainly refers to the hydraulic cylinder. The main function of the hydraulic cylinder parameters of its action function and pressure resistance, as the working medium fluid

through the sealed volume changes to transmit motion, by means of the internal pressure fluid to transmit power.
Second, the loader pressure monitoring
To ensure the loader hydraulic system's overall performance and technical indicators on hydraulic components for testing and adjustment, the hydraulic system as a whole should

also be detailed and thorough testing, in order to achieve proper coordination of each component work to ensure the stability of hydraulic system reliable.
Hydraulic system as a whole, including load testing and debugging debugging and load debugging. In the specific testing prior to a comprehensive inspection to be debugged loader

hydraulic system installed correctly, correct and reliable hydraulic lines, hydraulic oil grade is correct, whether compliance cleanliness requirements,

Oil inside the tank height meets the requirements, identify and correct before proceeding to the overall debugging.
A no-load monitoring and debugging
The purpose is to check the no-load debugging of hydraulic components in the system is working properly and the parameters of the various hydraulic components in the system to

adjust to the technical requirements, the machine stable and reliable performance.
When debugging, start the pump first load to rated speed operation, check the hydraulic system if there is abnormal sound transmission, while observing the instrument panel

indicates the number of oil pressure and oil temperature is normal, everything is normal, then the following operation.
Determine the hydraulic pump is working properly, then followed by manipulating the joystick, so that all elements are performed under no-load operation, speed from slow to

fast, the trip should be gradually increased until full speed run to exclude the air present in the system. Then, in no-load conditions, so that the implementation of the

components in the positive

Under normal operating procedures no-load operation. Check the correctness of each action and coordination, inspection of the action to start, stop, speed, smoothness of

transitions, check malfunction and "crawl", the impact of the phenomenon. Average load running 1-2h, and then check the oil pressure, oil temperature,

Leakage and so meet the requirements.
Although the components carried out during commissioning and testing of various parameters to adjust, no-load debugging process, but also a reasonable adjustment system pressure

value of each component regulator to ensure that the entire system is working properly and stable. Because the system pressure is adjusted improperly can cause both hydraulic

energy

Loss, so that the temperature rise would affect movement coordination, a run-up to the mechanical failure. Adjust the pressure value according to the actual use of technical

provisions or conditions of use, while actual use of the specific structure of various types of hydraulic components, the quantity and the circumstances of the specific sub-

pipeline

Analysis to determine the pressure range.
2 Load monitoring and debugging
Load debugging purposes is to check the hydraulic system after the load to bear, is able to achieve the intended work requirements, such as speed load characteristics, leakage

is serious, whether design or operational capacity maintenance requirements, the hydraulic system oil temperature is within the allowable range, etc. .
Load commissioning should be in a variety of possible conditions to test its ability to adapt to various working conditions. Entire commissioning process must be based from

simple to complex, from a single action to the principle of compound action, and test all work equipment movements. During the test, the pressure and flow

Volume, temperature, noise, leakage, etc. for the entire monitor, identify problems and timely recorded. A serious problem occurs, they should immediately be shut down for

inspection and exclusion.
Debugging process applications for performance parameter values ​​are not accurate, according to their works to the relevant adjustment device to adjust, so that the whole process

of debugging the various performance parameters gradually become normal, adjustment is ineffective when the analysis should be checked to find out reason, the components of the

repair or

Replacement.

Sidewall Conveyor Belt optimization improvements

To make the body sidewall conveyor belt carrying capacity is increased, sidewall conveyor belt body lateral bending load after minimal sidewall conveyor belt body that enhance

lateral rigidity is to reduce the lateral load deformation increases with body belt body carrying capacity of key . Lateral sidewall gravity conveyor body rigidity value refers

With a transverse vertical cross section of the body, with the body of free support on both sides of the edge, because sidewall conveyor belt body weight caused by band bending

under the weight of the body with body width value ratio. High lateral stiffness of the lateral rigidity sidewall gravity skatewheel conveyor technical standards is not greater than 0.05, the

right ribs lose

Belt structure with optimized and improved, additional lateral stiffness to enhance the lateral stiffness detector layer is 0.036, with a reduced lateral deformation after

carrying body, can increase the bearing capacity of 15% to 20%. Improved lateral stiffness large heavy sidewall conveyor belt is an effective measure to the body of the multi-

level baseband

Canvas interlaminar tensile body set up by special mixing and calendering dedicated polyester staple fiber composite layer, ie within a layer of polyester staple fibers in one

direction along the lateral arrangement with body buried layer. This has the sidewall conveyor belt body lateral bending capacity enhancement of the use of special composite

layer

The belt body lateral rigidity than conventional construction increased 2.5 times sidewall conveyor belt, even if its value is determined by lateral rigidity increased to 0.036

0.09.

eyor damaged what harm

The conveyor belt during operation of a variety of surface damage produced, the safe operation of the screw conveyor belt produces many adverse effects, which have the following main

points of Compliance:
(1) conveyor thinning, not easy to damage the surface of the lap belt to make it thinner, at both ends of the first lap occurs when joints of varying thickness, running and

roller sleeve bit startling produce strong scratching, wear both idlers, but also shorten the joint life, especially the new and the old belt lap belt is

More prominent. Curing method for the use of the connection spiral conveyor is not the same as the thickness, lap even more difficult.
(2) conveyor belt damage reduction in strength to a certain extent, especially in deep cover layer and the core layer after damage, directly affects the tensile strength of the

conveyor belt, and reduce its strength. Steel cord conveyor belt injury to the core when it could lead to corrosion of the steel cord inlet lose their strength

Degrees. Intensity variation conveyor belt during operation encountered a sudden increase in load, such as cars and start with a load cassette, etc., accident prone belt

breakage.
(3) damage to the conveyor belt life is shortened, the first layer is thinned so as to cover or expose the core, the belt prematurely, reducing the life of the belt, increasing

the transportation costs of the mine. For varying degrees of wear and tear on both sides of the center line of conveyor belt conveyor belt is concerned,

The tensile strength due to the local changes, but also further reduces the life of the belt.
(4) The conveyor belt running along the center line not the same degree of injury, both sides of the stretching ratio is changed frequently, a direct result of the deviation

conveyor is running, for correction even aggravated wear.

Reasons conveyor rubber aging effects

In the conveyor belt use, easy out items rubber layer aging, loss phenomenon, caused rubber aging factors about several aspects:
        1) Oxygen: Oxygen rubber in the rubber molecules with a radical chain reaction, molecular chain breakage or excessive cross-linking, causing changes in rubber

properties. Oxidation is a major reason for the aging of rubber.
        2) ozone, oxygen chemical activity is much higher than that, more destructive, it is also the molecule chain was broken, but the effects of ozone on the case with rubber

or deformation of rubber and different. As for the deformation of the rubber (mainly unsaturated rubber) occurs when the stress

Direction perpendicular to the cracking effect, the so-called "ozone cracking"; acting on the deformation of the rubber, not only the oxide film formed on the surface cracking.
       3)) Heat: raising the temperature may cause thermal cracking of rubber or thermal crosslinking. However, the basic effect of heat or activation. Improve oxygen diffusion

and activation of the oxidation reaction speed, thereby accelerating the oxidation reaction rate of the rubber, which is a common practice of aging - thermal aging.
      4) Light: light is shorter, the greater the energy. From the damaging effects of the rubber is high energy ultraviolet Flat belt conveyor  light. In addition to direct UV-strand breaks caused

by rubber molecules and crosslinking, the rubber due to absorption of light energy to produce free radicals to initiate and accelerate the oxidation chain reaction process.

Ultraviolet

Plays a role in the heating light. The role of the other characteristics of light (and heat different role) is that it mainly in the rubber surface of the Ascent. Gel sample

rate, net cracks will appear on both sides of the so-called "light outer crack."
      5) mechanical stress: the plastic chain conveyor in action as well as repeated mechanical stress and the constant friction roller process, will make the rubber molecular chains

generate free radicals induced oxidative chain reaction, forming force chemical processes. Mechanical rupture of molecular chains and mechanical activation oxidation process.

Which can account for

Advantages, depending on the conditions in which. In addition, under stress prone to ozone cracking.
      6) Water: the role of water has two aspects: rubber rain or humid air immersed in water, easily damaged, which is due to the rubber material and the water-soluble groups

and other ingredients were dissolved in water, extracted. Hydrolysis or absorption causes. And particularly in the water immersion

Alternating atmospheric exposure under the action will accelerate the destruction of the rubber. However, in some cases, water is not destroy the rubber, and even delay the

effects of aging.
     7) Other: on rubber factors include chemical media, variable valence metal ions, high-energy radiation, electrical and biological.

Belt conveyor is widely applied in the underground

  With the development of the coal industry, belt conveyors are widely used in the underground, but the conveyor belt fire accident has happened quite frequently, and some even

cause serious injury or death. Therefore, the analysis of Belt conveyor fire cause of the accident, and take appropriate safety precautions,

Belt conveyor on top anti-fire accidents particularly necessary.
       Belt conveyor belt fire causes much because of quality problems. Mine still use some non-flame-retardant or flame retardant poor belt. However, due to higher prices

retardant belts, especially coal enterprises to enter the market economy, the shortage of funds, poor non-flame retardant and flame retardant

The lack of timely replacement of the belt, and some manufacturers produce the best quality belts reach flame resistance requirements, which gave the conveyor belt fire

potential problems.
        Another aspect is the management of belt conveyors. Failure caused by belt conveyor belt conveyor belt fire due to the belt by the card, the belt and the roller friction

fire; roller, roller does not rotate or mechanical reasons prisoners slow speed, belts and rollers, idlers

Friction fire; belt conveyor hydraulic coupling injection can also cause belt conveyor fire. Inclined belt conveyor safety protection is not complete. According to Coal Mine

Safety Regulations: drum drive belt conveyor deviation must be equipped with anti-slip, anti pile of coal, anti-low-speed, anti-tear warranty

Protection and over-temperature sprinklers, smoke alarm device. But the scene is not complete or not these protections normal use, you can not effectively prevent accidents.
      Fire equipment is not complete or does not work and can not extinguish the fire source. According to rules of order: the main belt road dust every 50m must install two

pipes, each belt must be equipped with two fire extinguishers and a set number of retries sand box, but the scene is sometimes equipped with fire extinguishers missing or

invalid

Therefore, in the event of fire in the conveyor belt can not be extinguished. Open flames and ignite combustible materials due to the belt when the belt conveyor Road sparking

Select the conveyor belt when the need to pay attention to what matters



  In some areas of work, many factories will use the conveyor belt, conveyor belt because of the characteristics of a good, for the mechanical aspects of the use of very large,

in some factory staff also often require metal mesh belt, not only in the choice of when to pay attention to network with

Prices, the most important thing is to pay attention to the quality requirements of conveyor belt. Here's what the pallet conveyor selection to note:
1, the conveyor belt in the choice of when, not for low prices and choose inferior belt, so that in the actual operation, other devices will have some impact, would be

detrimental to the effective operation of the device, thus reducing the work of production quality and efficiency.
2, the choice of conveyor belt, be sure to choose cost-effective conveyor belt, so as to operate in the actual process of improving efficiency, easier operation of other

equipment, so the quality portable conveyor is really important.
Nowadays continuous conveyor belt used in many industries, for transportation also played a significant role in the actual choice of mesh belt when the need to pay attention to

a lot of problems. In order to ensure efficiency, do not because they are cheap, so as not to affect the progress of the work. So

Instead, the funds invested will be more.

Heat resistant conveyor belt introduce major structural properties and applications



        EPDM rubber heat resistant conveyor belt cover layer, reinforcing material with heat-resistant canvas using domestic unique formulation design, solved due EPR

saturation, poor adhesion, low adhesion between the layers off health problems. Heat resistant conveyor belt with a belt body

Light, long life (approximately 2-4 times), heat resistance and good.
       Heat resistant gravity conveyor is mainly used in metallurgy, construction and other industries, transportation sinter, coke, cement clinker and other high-temperature

materials, the material temperature does not exceed 800 ℃, with a surface temperature does not exceed 220 ℃ under the conditions of use.
Heat resistant conveyor belt also need to learn to maintain it!
         Now, no matter what products are needed and everyone else, we must learn to care, only to do reasonable maintenance in order to increase the pot life, then how do the

maintenance of high temperature resistant conveyor belt it, then we learn together below:
1, heat resistant conveyor belt to be at a temperature of between 18-40 ℃ and humidity of 50 - 80% of the environment preservation;
2, high temperature resistant Airport conveyor running to pay attention to timely adjust the running speed;
3, various types and specifications not heat resistant conveyor belt together with its joint bonding method to be used.
4, heat resistant conveyor belt in the use and preservation process, to avoid direct sunlight or wet snow, not with acids, alkalis, oils, organic solvents and other substances

in contact, to stay away from heating devices.
