ALL INFORMATION ABOUT SPECK MAKE WATER RING VACUUM PUMP
Design and functional principle
The pump is operated in accordance with the liquid ring principle.
The impeller is positioned off center in the cylindrical pump casing. It transfers the drive power to a liquid ring, which forms concentrically to the casing when the pump is started.
The gaseous medium remaining in the casing is distributed around the impeller due to the lower density in the hub area. As the impeller is positioned off-center to the casing, the available space for the gas between the surface of the liquid and the hub becomes crescent-shaped.
This way, the remaining space for the gas between the blades expands and shrinks during each rotation.
1 Suction opening
2 Pressure opening
3 Liquid ring
The arrangement of suction and pressure openings in the inter casing allows for the suction, compression and discharge of gas. The liquid both serves the sealing between the individual impel- ler chambers and the
absorption of heat produced during com- pression.
The pump must be permanently supplied with operating liquid during operation as a portion of the liquid continuously escapes from the pump together with the gas. The discharged operating liquid can be separated from the gas by means of a downstream separator and re-used.
