Like all machinery, liquid ring vacuum pumps also require regular inspections to ensure proper functioning. As a professional supplier, Atlas (Yantai) Vacuum Technology Co., Ltd. provides the following checklist for your reference:

1、Regularly inspect the vacuum pump pipes and connections for correct assembly. Rotate the liquid ring vacuum pump manually to check its flexibility.

2、Regularly inspect the bearing lubricating grease. Lubricating grease should be replaced or replenished promptly.

3、Check the bearing temperature during operation. The bearing temperature should not exceed 35°C above the ambient temperature, with a maximum temperature of 80°C.

4、If any abnormal noise is detected from the liquid ring vacuum pump, immediately shut it down and inspect the cause.

5、Regularly adjust the packing gland to ensure normal leakage from the packing chamber (a drip-type leakage is recommended).
