Adjust the length of the belt conveyor installation tips

 When we use the conveyor belt, the installation procedure is particularly important. To ensure correct installation of the belt can not only avoid unnecessary defects, and also

allows the belt to work better .
    When installing the conveyor advance roller conveyor for the entire conveyor belt to be installed careful planning calculations, whether new or old belt replacement belt installed ,

otherwise it is likely to cause the situation to take a long conveyor belt , is a direct consequence weight ( weight counterweight ) hits the ground,

Lead to start slipping. Although there was no problem , no problem test , but the position of the lower configuration , running two or three months later , with heavy drooping,

hit the ground when starting . This is because the installation process does not take into account Flexible Roller Conveyor the elastic deformation and plastic deformation of the belt . Conveyor Safety

When loading or too short , you should leave a margin for future maintenance. If the length of the minimum basic tension in the spiral . Joint problems after a period of use ,

the conveyor belt margin is not sufficient to redo the joints, had to re- install the new belt. This makes our conveyor cause

The white waste. While enabling enterprises subject to certain unnecessary losses. This is what we want to see the production situation . Ideal conveyor installation is that

after installing the conveyor belt of moderate length ( we should take into account summer and winter temperature differences affect the expansion of the conveyor belt ).

Best to reserve a margin joints , which can effectively prevent the installation length of inappropriate questions .
