Title:
LIQUID RING PUMPS WITH IMPROVED HOUSING SHAPE
Document Type and Number:
Japanese Patent JPH0642478
Kind Code:
A
Abstract:
PURPOSE: To obtain a liquid ring pump by shaping an inner surface of a housing so as to reduce fluid friction loss within the pump.
CONSTITUTION: In a liquid ring gas pumps of the type having a rotor 20 rotatably mounted in a stationary housing 12 for forming a quantity of pumping liquid into a circulating ring inside the housing 12, fluid friction loss between the liquid and the housing 12 is reduced by shaping an housing inner surface 15a which is in contact with a liquid ring radially outside the rotor 20 so as to minimize or at least substantially reduce an area of that inner surface 15a.
