Title:
CENTRIFUGAL PUMP
Document Type and Number:
WIPO Patent Application WO/2018/154931
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a centrifugal pump with which thinning is achieved by using a radial gap type motor, with which flow passage losses from a suction flow passage to a discharge flow passage are small, and with which it is possible for heat generated in a coil to be dissipated efficiently without providing a special cooling structure. As a means of overcoming the problem, a rotor (13) and a pump main body (2) are disposed concentrically about a rotor shaft (7), and a suction side scroll flow passage (14) and a discharge side scroll flow passage (15) formed in the pump main body (2) communicate with one another by way of a central flow passage (10b), (10a) formed in the pump main body (2) and in an impeller (9).
