CENTRIFUGAL PUMP

摘要

FIELD: engines and pumps.SUBSTANCE: centrifugal pump comprises a body with an inlet nozzle changing into the central part of the body. The central part of the body changes into a discharge nozzle. In the central part of the body there is an impeller of tunnel type. On the front circular disc of the wheel there are circular channels. On the inner wall of the central part of the body upstream the inlet to the discharge nozzle there is a step. On the inner side of the body cover installed at the side of the inlet nozzle there are circular collars.EFFECT: increased efficiency factor and maximum permissible speed of rotation and reduced head resistance to rotation and noise level.3 dwg
