Vacuum pump belt
Thread Content
The company has a vacuum pump driven by four V-belts, and recently these V-belts have been breaking frequently (there are even signs of melting on them). What could be the causes of this failure?
Check the pump; it’s likely there’s a problem with it.
The load may be too high, or the four belts may not be under even stress. Another possibility is that the pump and the pulley of the drive motor are not in the same plane
Reply to 2# yuchenchf: Thank you, but no issues were found during the on-site inspection; temperature, pressure, and vibration were all within normal ranges.
Reply to 3# 565026033 Thank you! The temperature and pressure at the inlet and outlet are within normal ranges. The alignment of the pulley has also been done.
Has there been any change in the material of the belt or in the forces it is subjected to?
Reply to 6# Hongcaohao: Thank you for your reply. The material information should be available, but how can one find out about changes in stress? . . . .
