After using the vacuum pump unit, we generally need to adjust it to facilitate its next use. In order to ensure the quality and service life of the product, we need to maintain and monitor it. The main purpose is to ensure its normal operation. What should we do?
1. Check the indication of separator liquid level gauge, which is about 20mm 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 more than 6 ℃ lower than the water temperature of condenser hot well, otherwise the vacuum will be affected.
3. Check the pump body temperature of the vacuum pump unit, which shall not be higher than the sealing water temperature by 14 ℃, otherwise the pump shall be stopped for treatment.
4. Check the temperature of the bearing box, which shall not be higher than the temperature of the pump body by 17 ℃, otherwise the pump shall be stopped for treatment.
5. There is a small amount of water dripping at the packing, and the packing is not hot.
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 sequence, otherwise, there may be some misunderstandings due to the inspection, so when we deal with it, it will be a little troublesome.
