Embodiment Construction

[0015] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] see Figure 1 to Figure 5 , a vacuum centrifugal pump 10 according to an embodiment of the present invention includes a motor 20 , a volute 40 mounted on one side of the motor 20 , and an impeller 60 located in the volute 40 and mounted to the output shaft of the motor 20 .

[0017] The volute 40 includes an inlet 42 arranged axially, an outlet 44 arranged laterally, and a flow channel 46 arranged substantially circumferentially. The flow channel 46 is helical, and its cross-sectional area (water passing area) gradually increases along the direction close t...

Abstract

The invention provides a vacuum centrifugal pump. The vacuum centrifugal pump comprises a motor with an output shaft, a volute installed on one side of the motor and an impeller positioned in the volute and installed on the output shaft of the motor, wherein the volute comprises an inlet formed in the axial direction, an outlet formed in the lateral direction and a flow passage arranged in the circumferential direction, wherein the flow passage is in a spiral shape, and the cross sectional area gradually increases in the direction close to the outlet. The vacuum centrifugal pump provided by the embodiment, the flow passage in the volute is designed by adopting a spiral line, so that the flow passage accords with flowing of water flow, the loss of the water flow can be reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to a vacuum centrifugal pump, which can be applied to various household washing equipment such as washing machines and dishwashers. Background technique [0002] Various household washing equipment such as washing machines and dishwashers are used more and more widely. A vacuum centrifugal pump is a key component in washing equipment, and the performance of a vacuum centrifugal pump directly determines the performance of the washing equipment. The existing vacuum centrifugal pump has some defects due to the design of the volute and the impeller, such as the water passing area of ​​the volute changes according to the equicircle, and has the disadvantages of large water flow loss and the like. The invention aims to develop a novel vacuum centrifugal pump with small water flow loss. Contents of the invention [0003] The technical solution adopted by the present invention to solve the existing technical problems is: a vacuum cent...
