The circulating water vacuum pump is an important vacuum equipment, and its normal operation is crucial for the smooth progress of experiments and technological processes. In order to ensure the long-term stable operation of the circulating water vacuum pump and extend its service life, the following are several key maintenance and upkeep points:

1. Regular cleaning and inspection

Regular cleaning is an important step in maintaining the performance of circulating water vacuum pumps. Start by turning off the power and disconnecting the water source. After the pump body cools down, use a mild cleaning agent and soft cloth to wipe the pump body casing and components. Be careful not to use corrosive cleaning agents to avoid damaging the surface of the pump. Check the pump body, pipelines, and connections for looseness or water leakage, and make necessary tightening and repairs.

2. Lubrication and maintenance

Circulating water vacuum pumps usually have a lubrication system that requires regular inspection and maintenance. The selection of lubricants should comply with the specifications and requirements of the pump. Regularly check the level and cleanliness of the lubricating oil or grease in the lubrication system, and add or replace as needed. At the same time, check and clean the filter element and filter screen of the lubrication system to ensure the quality and fluidity of the lubricating oil.

3. Check sealing and consumables

The seals and consumables of the circulating water vacuum pump are crucial for maintaining good vacuum and performance. Regularly check the wear and aging of sealing components, such as O-rings and gaskets, and replace them promptly if any problems are found. In addition, pay attention to inspecting and replacing other consumables, such as filter elements, filters, and water pipes, to ensure the normal operation of the system.

4. Correct operation and protection

Correct operation and protection are the key to extending the service life of circulating water vacuum pumps. Follow the operating instructions in the user manual to avoid overloading and prolonged continuous operation. In addition, it is also important to protect the circulating water vacuum pump from dust, moisture, and chemical erosion. During use, the pump should be placed in a dry and clean environment and avoid contact with corrosive gases or liquids. Regularly inspect and clean the inlet and outlet of the pump to prevent blockage and accumulation.

5. Regular maintenance and upkeep records

Establishing regular maintenance and upkeep records is a good practice that can help track pump performance and historical maintenance status. Record the maintenance date, maintenance content, and identified issues, and take corresponding corrective measures in a timely manner. This helps to identify potential problems in a timely manner and prevent malfunctions in advance.

The maintenance and upkeep of the circulating water vacuum pump is crucial for ensuring its normal operation and extending its service life. Regular cleaning and inspection, lubrication and maintenance, inspection of seals and consumables, correct operation and protection, and establishment of maintenance records are all key measures to maintain stable performance and extend the service life of circulating water vacuum pumps. Reasonable maintenance and upkeep measures can improve the reliability of equipment, reduce the occurrence of faults, and ensure the smooth progress of experiments and processes. Therefore, researchers and operators should attach importance to the maintenance of the circulating water vacuum pump and carry out regular maintenance according to the operating instructions and manufacturer's recommendations.
