After the vacuum pump unit is used up, we generally need to adjust it to facilitate the next use. In order to ensure the quality and service life of the product, we need to carry out certain maintenance and monitoring. Its main purpose is to ensure its normal operation. How should we do it?

1. Check the indicator of separator level gauge, which is about 20 mm, and can not be too high or too low. Too high will damage the impeller, too low will affect the vacuum.

2. Check the sealing water temperature, which should be 6 ℃ lower than the condenser hot well water temperature, otherwise the vacuum will be affected.

3. Check the temperature of the pump body of the vacuum pump unit, which should not be higher than 14 ℃ of the sealing water temperature, or the pump should be stopped for treatment.

4. Check the bearing box temperature, which should not be higher than 17 ℃ of the pump body temperature, or stop the pump for treatment.

5. There is a small amount of water drop at the packing, and the packing does not heat.

6. The sealing water pressure is 0.07MPa.

7. Check that the vibration, sound and smell of vacuum pump and seal water pump are normal.

When we monitor and adjust the vacuum pump unit, we must operate according to the normal order, otherwise, there may be some misunderstanding due to the inspection, so when dealing with it, it will be a little troublesome.
