Embodiment

[0037] A self-priming pump water pipe connection structure, such as figure 1 , figure 2 As shown, it includes a pipeline 1 arranged on the water inlet or outlet of the pump body 18 of the self-priming pump. The end of the pipeline 1 away from the pump body 18 is connected with a connecting pipe 2, and the diameter of the connecting pipe 2 is smaller than that of the pipeline 1. set up. The pipe diameter of the connecting pipe 2 is constricted toward the direction away from the pump body 18, and the outer wall of the connecting pipe 2 is also provided with several anti-slip grooves 3 along the axial direction. When the pipeline 1 needs to be connected with a water pipe, the connecting pipe 2 can be used for socketing the water pipe.

[0038] Such as figure 2 , image 3 As shown, the end of the connecting pipe 2 close to the pipeline 1 is also provided with a connecting section 4 threadedly connected with the pipeline 1, the outer wall of the connecting section 4 is provid...

Abstract

The invention discloses a self-sucking pump water pipe connection structure and relates to the technical field of water pumps. According to the main points of the technical scheme, the self-sucking pump water pipe connection structure comprises a pipeline arranged at the water inlet end or the water outlet end; a connection pipe used for sleeved connection of a water pipe is connected to the end,away from a pump body, of the pipeline; the pipe diameter of the connection pipe is smaller than the pipe diameter of the pipeline; a casing is in threaded connection with the outer side wall of the pipeline; a flange plate is arranged at the end, away from the pump body, of the casing; the flange plate is fixed to the outer side wall of the casing and is provided with a plurality of through holesin the circumferential direction; a compression ring is further in threaded connection with the inner side wall of the casing; the compression ring is in threaded connection with the end, away from the pump body, of the casing; and the compression ring is used for compressing the water pipe on the connection pipe. The flange plate, the connection pipe and the compression ring are arranged, thus aself-sucking pump can be connected with the water pipe with the flange plate and can also be connected with the water pipe directly, connection suitability of the water inlet end or the water outletend is higher, and connection of the self-sucking pump and the water pipe is more convenient.

Description

technical field [0001] The invention relates to the technical field of water pumps, more specifically, it relates to a water pipe connection structure of a self-priming pump. Background technique [0002] The self-priming pump has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. [0003] The water inlet or water outlet on the pump body of the existing self-priming pump is usually provided with a flange, and the flange on the water inlet or water outlet is connected with the flange on the water pipe by bolts, thereby Make the self-priming pump run. However, each connection requires a flange to be docked. When no flange is provided on the water pipe, the connection between the self-priming pump and the water pipe is cumbersome. The self-priming pump generally has poor adaptability and needs to be improved. Contents of the invention [0004] Aiming at the deficiencies ...
