Troubleshooting of desktop circulating water vacuum pump:

1. Oil leakage: During the use of a vacuum pump, oil leakage may cause a decrease in oil level, affecting the efficiency of the pump. If oil leakage is found, the vacuum pump should be turned off in a timely manner, the cause of the leakage should be identified, and then repaired. Common causes of leakage include oil seal damage, loose pipelines, poor sealing, etc. Different treatment methods need to be adopted for different leakage causes, such as replacing oil seals, tightening pipelines, replacing seals, etc.

2. Overheating: Vacuum pumps may shut down during operation due to overheating of components such as motors, bearings, gears, etc. The main reasons for overheating include insufficient bearing lubrication, bearing damage, and high mechanical resistance. Once the vacuum pump is found to be overheated, it should be stopped in a timely manner and checked for sufficient bearing lubrication, bearing damage, and high mechanical resistance. Corresponding measures should be taken for different reasons, such as adding lubricating oil, replacing bearings, and clearing mechanical faults.

3. Excessive noise: It is normal for a vacuum pump to make a certain amount of noise during operation, but if the noise is too loud, it may be caused by bearing damage, poor gear meshing, mechanical failure, and other reasons. Once excessive noise is detected, the machine should be stopped in a timely manner, and the bearings and gears should be checked for damage, poor meshing, mechanical faults, etc. Corresponding measures should be taken for different reasons, such as replacing bearings, replacing gears, and eliminating mechanical faults.
