With the wide application of vacuum pumps in industry, various faults of vacuum pumps in the process of operation are also generated, and the common problems and repairs encountered in the operation of vacuum pumps are summarized.
1. Common faults and causes of vacuum pumps.
1.Leakage failure: Poor sealing of the pump body or aging and damage of the seal is a common cause of leakage of the pump body. In addition, leakage can also be caused by poor sealing of connecting pipes and joints, and excessive negative pressure inside the pump body.
2.Abrasion and corrosion: Vacuum pumps that have been used for a long time or work in harsh environments often experience wear and corrosion, such as impeller wear, rust in the pump casing, etc., which can lead to a decrease in the efficiency of the pump.
3.Bearing failure: Due to long-term high-speed rotation, the bearing is easy to wear and loosen, resulting in high noise and increased vibration, which in turn affects the normal operation of the vacuum pump.
4.Blockage of air inlet: Due to the dust and impurities entering the pump body in the working environment, it is easy to cause the air inlet to be blocked, which hinders the work of the vacuum pump.
5.Too high temperature: The working temperature of the vacuum pump body is too high for a long time, which will cause serious consequences such as aging of the seal and even burning out the motor.
Second, the treatment method of common faults of vacuum pumps.
1.Solve the leakage problem: first of all, check and replace the pump body seal; Inspect and maintain the connecting pipes and joints to ensure good sealing; If the leakage is caused by excessive negative pressure, the negative pressure inside the pump body should be adjusted appropriately.
2.Repair of wear and corrosion: Repair or replace the impeller and derust the pump casing to ensure that the inner wall of the pump is smooth. In addition, the pump body is cleaned regularly and protected with an anti-corrosion lubricant.
3.Repair of bearing failure: regularly check the wear degree of the bearing, and replace it if necessary; Add lubricating oil regularly to keep the bearings lubricated properly.
4.Cleaning of air inlet blockage: Clean the vacuum pump regularly, and install a suitable filter to prevent dust and impurities from entering the pump body and keep the air inlet unblocked.
5.Control the temperature of the vacuum pump: By adding a radiator or installing a fan, the temperature of the pump body can be effectively reduced to avoid failures caused by excessive temperature.
Common faults and repairs for vacuum pumps include leakage problem solving, wear and corrosion repair, bearing fault repair, air inlet blockage cleaning, and high temperatures. In daily use, having a certain understanding of these problems can improve the efficiency of the equipment.
