Embodiment 1

[0036] In this example, if Figure 1 to Figure 4 As shown, the liquid inlet 21 and the liquid outlet 22 are respectively provided on two opposite surfaces of the main body 20 , and the valve installation port 23 is provided on the surface adjacent to the surface where the liquid inlet 21 is located.

Embodiment 2

[0038] In this example, if Figure 5 to Figure 8 As shown, the liquid inlet 21 and the valve installation port 23 are opened on two opposite surfaces of the main body 20 respectively, and the liquid outlet 22 is opened on the surface adjacent to the surface where the liquid inlet 21 is located.

[0039] The advantages of the pump body and the twin-screw pump disclosed by the present invention are:

[0040] 1. By setting the inside of the main body 20 as a rectangular cavity 30, the volume in the cavity is increased, thereby increasing the "drinking" water volume of the cavity, and under the driving action of the two screws, sufficient liquid flow can be provided, and Effectively provides the power of the pump.

[0041] 2. The pump body with the above structure reduces the noise of pump operation.

Abstract

The invention discloses a pump body and a double-screw pump. The pump body comprises a sleeve body and a main body, wherein two communicating hole cavities are formed in the sleeve body for installingtwo screws; a rectangular cavity is formed in the main body, and the sleeve body is located in the rectangular cavity; the main body has a rectangular shape; and a liquid inlet, a liquid outlet and avalve mounting port which communicate with the rectangular cavity are formed in the surface of the main body. Due to the fact that the rectangular cavity is formed in the main body, the volume in thecavity is increased, the draft amount of the cavity is increased accordingly, enough liquid flow can be provided under the transmission action of the two screws, and the power of the pump is effectively improved.

Description

technical field [0001] The invention relates to a pump body of a twin-screw pump and the twin-screw pump. Background technique [0002] The pump body of the twin-screw pump in the prior art includes a casing for including the screw and a main body located outside the casing, and a liquid inlet and a liquid outlet are opened on the main body so that under the action of the twin-screw meshing rotation , the liquid enters from the liquid inlet and flows out from the liquid outlet. [0003] The main body of the pump body in the prior art is cylindrical, resulting in a small space defined between the main body and the casing, resulting in a small volume of the space, resulting in small power and supply liquid flow of the screw pump. Contents of the invention [0004] Aiming at the above-mentioned technical problems existing in the prior art, the embodiment of the present invention provides a pump body and a twin-screw pump. [0005] In order to solve the problems of the techn...
