Title:
ROTARY PUMP
Document Type and Number:
WIPO Patent Application WO/2002/097272
Kind Code:
A1
Abstract:
The invention relates to mechanical engineering, in particular to the design structure of rotary pumps. The aim of said invention is to improve the economy characteristics and the efficiency of a pump, to increase the height of self-suction of the pump and reduce the production costs thereof. The intermediate chambers of the inventive pump are embodied in such a way that they are connectable to a suction chamber and a discharge chamber, if any. The inventive rotary pump makes it possible to obtain the optimal scheme of application of active forces (from the rotors rotated by the pump drive) to the pumped fluid.
