A guide to the installation, maintenance and efficient operation of water ring vacuum pumps

Installation should ensure that the pump body is fixed horizontally, that the inlet line is short and straight and higher than the center line of the pump inlet, and that the outlet line avoids right-angle elbows to reduce resistance. It is recommended to configure cavitation protection pipe and separator, and activate the protection mechanism when the suction pressure is lower than 80mbar to prevent cavitation damage in the pump chamber. Daily maintenance should focus on checking the wear of packing seals, cleaning up the scale of the water-gas separator every quarter, and monitoring the circulating water temperature (≤40°C). If the vacuum level drops, it is necessary to check the problem of stuck in the imported check valve or fatigue fracture of the distributor valve - the fracture of the valve will cause the shaft power to increase by more than 15%, and it is necessary to replace the new PTFE material in time. The equipment supports belt or direct drive, and the supporting electronic control system can realize real-time adjustment of flow and pressure, ensuring that 97% vacuum (33mbar absolute pressure) can still be maintained under continuous high load conditions, providing stable and reliable vacuum power support for the factory.
