At present, many domestic enterprises use imported vacuum pumps, such as Alcatel vacuum pump, Laibao vacuum pump, Edward vacuum pump, Pushu vacuum pump, richelor vacuum pump, Beck vacuum pump, etc. Although the performance of imported vacuum pump is good, but it involves maintenance and after-sales service, it is best to find a professional manufacturer, and some unprofessional vacuum pump maintenance personnel Not only can not solve the technical problems, but also cause the secondary damage of the imported vacuum pump.

However, before maintenance, we should try our best to do a good job of maintenance. The correct maintenance of the imported circulating water vacuum pump can reduce the difficulty of the maintenance of the imported vacuum pump. Dalutong provides some suggestions for the enterprises using the imported vacuum pump for your reference

1. If it is a rotary vane vacuum pump, it should be installed in a clean and clean environment, and there should be no debris, dust, water source and high temperature area.

2. When installing the imported vacuum pump for the first time, check whether the motor rotates in the forward direction, that is, the rotation direction of the motor is consistent with that of the rotor in the pump. Generally, the normal running direction of the motor is marked on the top of the motor.

3. Start the vacuum pump intermittently and several times before starting the vacuum pump after a long shutdown.

4. After using the vacuum pump, the vacuum pump should be drained.

5. When the vacuum pump is running, the oil temperature should not be higher than 75 degrees. Please contact the vacuum pump manufacturer in case of failure.

6. If the vacuum pump has the potential danger of inhaling impurities, dust, water, chemical substances, etc., a precision filter should be installed at the air inlet of the vacuum pump. If the amount of impurities, dust and water is too large, a storage tank must be installed for filtration, so as to prevent the dust, water, chemical substances and other impurities from entering the vacuum pump.

7. If the vacuum pump needs to run for 24 hours, it must be maintained every six months

8. During the normal operation of the vacuum pump, the vacuum pump oil in the pump should not be lower than the oil mark. It should be at 2 / 3 of the oil mirror. It is strictly forbidden to mix with vacuum pump oil of different brands and models when refueling.

9. The vacuum pump oil should be replaced regularly, generally once every 3-6 months. If the pump oil is found to be emulsified or carbonized, the special oil for vacuum pump should be replaced in time.

In fact, the maintenance method of imported circulating water vacuum pump is similar to that of domestic vacuum pump. There are some fake imported vacuum pump accessories on the market. If your imported vacuum pump fails and needs to be replaced, you must find a regular manufacturer. The fake imported vacuum pump accessories may be normal for the first time and the second time. After several times of use, the genuine and counterfeit ones will be compared.

The circulating water vacuum pump with good quality will have some problems after long-term operation, such as:

1. The exhaust port of vacuum pump smokes

2. Fuel injection and oil leakage of vacuum pump

3. The noise of vacuum pump exceeds the standard

4. Vacuum drop

5. Vacuum pump hot phenomenon.
