Introduction to Oil Ring Vacuum Pump

An oil ring vacuum pump is a type of positive - displacement pump that uses an oil ring to create a seal and generate vacuum. It operates based on the principle that the rotating impeller throws the oil to the inner wall of the pump casing, forming a moving oil ring. This oil ring acts as a piston, compressing and displacing the gas to be evacuated. Oil ring vacuum pumps are widely used in various industries such as chemical, pharmaceutical, food processing, and power generation due to their simple structure, reliable operation, and ability to handle a wide range of gases and vapors.
