circulating water vacuum pump troubleshooting
Several methods for troubleshooting of circulating water vacuum pump
The circulating water vacuum pump is a product of centrifugal pump type. The temperature of circulating water vacuum pump is less than 120 ℃. The problems of circulating water vacuum pump mainly include no water, lack of flow, noise oscillation, water leakage, etc. today, we will share the following fault factors and treatment scheme, hoping to be useful to us!
No. 1, vacuum can't keep up, maybe the target of vacuum gauge is not accurate
The first part of this kind of problem is the motor. It may be that the speed is not good or the voltage is low. It is necessary to check whether the voltage is stable or not. It may also be that the vacuum bottle and check valve are dirty and blocked or corroded. It is necessary to clean up the dirt or replace the new bottle or valve core. If the water inlet and filter network are blocked, it is necessary to clean and take out the dirt. Maybe the instrument bell vacuum meter has water or air leakage. The water in the vacuum meter should be thrown out or replaced with a new one. If the vacuum tube is colored or cracked, it should be replaced with a new tube.
Second, the motor does not work
It is most likely that the fuse is blown out. It is only necessary to replace a new fuse. It may be that the operating capacitor is broken down or the motor winding is burnt out. These all need to update the new capacitor and motor. If the bearing is seriously worn and stuck, the new bearing should be replaced and the impeller is blocked. After sorting out the sundries, the impeller orientation should be checked.
Third, the motor is hot and noisy
Usually bearing wear, impeller wear or voltage instability or low voltage, need to replace the new bearing and impeller, check whether the circuit is overloaded.
The above is the common problem of circulating water vacuum pump, that is, the treatment method. If it is still unable to be handled, it is necessary to find an expert to deal with it as soon as possible, so as to avoid invalidation of vacuum pump.
