However, as time goes by, the vacuum pump will inevitably encounter various failures, which will affect the production progress. This article will delve into the common faults and solutions of vacuum pumps, daily maintenance skills, brand recommendations, advantages and disadvantages, and share how to choose a suitable vacuum pump maintenance service provider, as well as precautions during the maintenance process, to help you easily control the vacuum pump and ensure production No worries.

1. Common faults and solutions of vacuum pumps

● 1. Air leakage problem: Air leakage is one of the most common failures of vacuum pumps, which may be caused by aging seals, loose pipe connections, etc. Solutions include replacing new seals, tightening pipe connections, and regularly checking sealing performance.

● 2. Pump oil contamination: Oil contamination of oil-sealed vacuum pumps will lead to a decrease in pump performance. Regularly changing the pump oil, using qualified oil, and installing an oil filter can effectively prevent this problem.

● 3. Increased noise: Bearing wear, impeller imbalance, etc. will cause the vacuum pump noise to increase. Worn parts need to be checked and replaced in time to keep the equipment balanced.

● 4. Insufficient air pumping capacity: This may be related to scale accumulation inside the pump body, blade wear or motor failure. Internal cleaning, replacement of worn parts or motor maintenance is required.

2. Vacuum pump daily maintenance skills

● 1. Replace the pump oil regularly: According to the requirements of the instruction manual, replace the pump oil regularly to keep the oil clean.

● 2. Clean the cooling system: Make sure the heat sink is not blocked by dust and maintain good heat dissipation performance.

● 3. Check the seals: Check the seals regularly for aging and damage, and replace them in time to ensure sealing performance.

● 4. Monitor the operating sound: Monitor the operating sound of the vacuum pump regularly, and detect and deal with abnormal sounds in time.

3. Vacuum pump brand recommendations and their advantages and disadvantages
