VACUUM LIQUID-RING PUMP Russian patent published in 2008 - IPC F04C7/00 F04C19/00 F04C14/22 F04C28/22 

FIELD: vacuum engineering; compressors.

SUBSTANCE: proposed vacuum liquid-ring has housing, hollow working wheel with blades forming working chambers arranged with clearance in housing for rotation, and distributing hollow shaft with partition forming inlet branch pipe at one side and outlet branch pipe at other side. Fixed parts of bearings are fitted on shaft with eccentricity. Channels to let in and let out liquid are made in bearings. Housing is installed for rotation by electric motor forming liquid ring. Working wheel is freely fitted on shaft on bearings and is made up two end face disks and radial flat blades rigidly connected with disks and furnished with seals arranged form side of shaft. Shaft is installed on inner eccentric bushings arranged in outer eccentric bushings found in fixed parts of bearings whose movable parts are secured in housing. Bushings are made for independent turning relative to each other in fixed parts of bearings by means of mechanical drives in form of leverages to shift hollow shaft along vertical axis and adjust eccentricity between hollow shaft and housing in process of operation of pump.

EFFECT: provision of liquid-ring vacuum machine with mechanism to adjust eccentricity between shaft and housing providing simple operation and reduced number of manipulations.
