Problems solved by technology

[0002] In the related art, when it is necessary to both heat the fluid and pump the heated fluid, a heating device and a pumping device are usually provided, and the structure of the equipment is complicated, the volume is huge, and the space utilization rate is low
For this reason, there has been a device that embeds the heating device in whole or part of the pump casing to combine the heating device with the pumping device. However, since the heater can only be processed into a regular circular shape, the pump casing cannot follow the spiral shape. Shape design, poor hydraulic performance

Abstract

The invention discloses a centrifugal pump. The centrifugal pump comprises a pump shell, a heating device, a guide part and an impeller, wherein the pump shell is internally provided with a heating cavity and a pump cavity communicating with the heating cavity; an inlet communicating with the heating cavity and an outlet communicating with the pump cavity are formed in the pump shell; the heating device is arranged on the pump shell; the guide part is arranged in the heating cavity; the guide part defines a diffusing flow path for guiding a fluid entering form the inlet to outwards diffuse in a radial direction of the heating device and a centralizing flow path for guiding the diffused fluid to integrally centralize to a pump cavity in the radial direction of the heating device; and the impeller is arranged in the pump cavity and used for guiding the fluid which is centralized to the pump cavity to the outlet. The centrifugal pump disclosed by the invention is compact in structure, small in size, high in space utilization rate; and moreover, the pump shell surrounding the impeller can be designed into a spiral shape, so that the hydraulic performance is good.

Description

technical field [0001] The invention relates to the technical field of pumping, in particular to a centrifugal pump. Background technique [0002] In the related art, when it is necessary to both heat the fluid and pump the heated fluid, a heating device and a pumping device are usually provided, and the equipment has a complex structure, a large volume, and a low space utilization rate. For this reason, there has been a device that embeds the heating device in whole or part of the pump casing to combine the heating device with the pumping device. However, since the heater can only be processed into a regular circular shape, the pump casing cannot follow the spiral shape. Shape design, poor hydraulic performance. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide a centrifugal pump, which has the advantages of simple structure, good hydr...
