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.
