Principles of food security equipment and conveyor drive pulley friction coefficient

   The calculation results with different belt conveyor design may vary , the most critical parameter is the value of the running resistance coefficient and the coefficient of

friction . Changes in mine production Incline Belt conveyor system , change the belt conveyor running resistance coefficient and the coefficient of friction and other environmental conditions.

Therefore , the actual measurement

Results found in the data sheet Flat belt conveyor and field a considerable difference , which is calculated from the selected parameters of any conventional large result .
    The power of hypothesis-driven traction rollers , to overcome all the running resistance , the ideal tape friction drive mechanism , friction and heat is not considered to

bring about the change .
    Principles running drag coefficient : belt conveyor is running, the motor load input power and input current measurement . A single motor drives the belt conveyor load

operation , electrical power measurements , calculated shaft power ( eg motor efficiency can be measured , reducer coupling efficiency and effectiveness

Yi , the calculated value is accurate, on-site experience is based on the universal values ​​) , based on the relationship between shaft power, traction and running between the

drag coefficient can be calculated resistance operation.
    Principles of food security equipment and conveyor drive pulley coefficient of friction : the sliding friction test method key determination. Will be placed in the

electrical parameters of the no-load belt conveyor is running , multi-drive conveyor unit of measure to alleviate ( the best is to open a single motor and other machines

EMU temporarily out ) , control power , the drive roller张力刚slide , pull the rope taut record read ( depending on the tensioning device , specific conditions ) , and then

slightly tighten the slip state, when the tense recording program , and motor power .
