Vacuum pumps, as powerful assistants in the industrial field, are inevitably prone to some malfunctions after prolonged use. Don't worry, below we will reveal common faults and their solutions for you!
Unable to start?
Firstly, check the circuit to see if the fuse is burnt or if the circuit components are damaged. If the circuit is fine, it may be a problem with the motor. Motor damage is usually related to excessive current or bearing wear. In this case, it is necessary to check the condition of the bearings, replace them if damaged, and repair or replace the motor if the coil is burned out.
Can't reach the highest vacuum level?
First check the sealing of the vacuum system to ensure there is no air leakage. Then turn on the gas chamber and let the pump run for a period of time to eliminate the influence of compressible steam. Other possible reasons include pump oil contamination, clogged oil filters, and deformed oil distributor valves, which require oil replacement, filter cleaning, and valve replacement.
Oil leakage problem?
This is a common fault of rotary vane mechanical vacuum pumps, which usually occurs in positions such as oil windows, oil tank gaskets, and motor bearing shaft seals. Long term use can cause these components to age and seal failure. The solution is to replace the aging components and use a vacuum pump to flush and clean the filter screen at the oil injection port, keeping the oil tank clean.
