Definition and Classification of Water Ring Vacuum Pumps
A water ring vacuum pump is a commonly used vacuum pumping device, mainly used to extract gas or vapor from a closed container, reducing its internal pressure to achieve a vacuum. Based on its structure and working principle, water ring vacuum pumps can be classified into single-stage, two-stage, and multi-stage water ring vacuum pumps.
Technical Requirements for Water Ring Vacuum Pumps
Technical Parameters: The technical parameters of water ring vacuum pumps should comply with the provisions of national standard GB/T 13929.
Mechanical Strength: The mechanical strength of water ring vacuum pumps should comply with the provisions of national standard GB/T 13929, and be able to withstand various forces and pressures under predetermined working conditions.
Sealing Performance: The sealing performance of water ring vacuum pumps should comply with the provisions of national standard GB/T 13929, ensuring that the vacuum pump does not leak during operation.
Overall Vibration: The overall vibration of water ring vacuum pumps should comply with the provisions of national standard GB/T 13929, and should not affect the normal operation and service life of the equipment.
