The pulley belongs to the wear part, and sometimes there will be the phenomenon of jitter and skidding during the long running process. Sometimes it does not check it regularly. After a period of time, it will also cause damage to the machine. In serious case, it may be damaged directly, so we have to use the pulley regularly in the daily use. Examination:
1. Surface
All the standard pulley is weighted according to the standard. If there is a big bump on the surface of the pulley, it is necessary to observe whether the pulley is jitter during the operation, and if there is a jitter, the pulley will not continue to use.
2. Belt
The belt pulley is driven by the belt, so we also need to check the belt regularly. We should observe the tightness of the belt first after the installation. If the installation is too tight, it will affect the speed of the pulley, and it may wear the motor shaft when it is serious. If the installation is too loose, the machine may reduce the machine. The efficiency of work, the phenomenon of slippery, regularly check the belt, if the belt aging tension is not enough, then we need to change the belt in time.

3.The mounting hole of the pulley is a direct contact with the motor shaft. It is also an important part of the machine. We need to observe regularly whether the installation holes are clean and whether there are impurities in it, because if there is a magazine that needs to be cleaned in time, the magazine is likely to damage the installation holes and if the installation holes are damaged, Then the pulley will not be used.
