Special sealing type pump body fastening connector

Abstract

The invention relates to the technical field of blow-down pumps, in particular to a special sealing type pump body fastening connector. According to the technical scheme adopted by the invention, thespecial sealing type pump body fastening connector comprises a cylindrical main body supporting connecting column, wherein the left side of the main body supporting connecting column is equipped witha first tight assembly connecting disc which is integrally formed; the right side of the first tight assembly connecting disc is equipped with a spherical structure; the sphere center of the first tight assembly connecting disc is arranged at the left side of the main body structure of the first tight assembly connecting disc; a cylindrical first reinforcing connecting column which is integrally formed is arranged on the left side end surface of the first tight assembly connecting disc; the center shaft of the first reinforcing connecting column is the same with the center shaft of the main body supporting connecting column; and the center position of the left side of the first reinforcing connecting column is equipped with a cylindrical assembly positioning connecting column which is integrally formed. The special sealing type pump body fastening connector has the advantages that: a plurality of tight assembly connecting disc structures are arranged on the main body structure, so thatintegral assembly connecting attachment strength of the blow-down pump is better; and moreover, the special sealing type pump body fastening connector is more convenient during assembly.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to a special sealing type fastening connector for a pump body. Background technique [0002] The sewage pump is a pump product used in the environmental protection industry to transport solid-liquid mixed liquids containing solid particles, fibers, etc., such as domestic sewage, industrial wastewater, mud, etc. With the development and progress of society, there are more and more domestic sewage and industrial sewage, so it is necessary to discharge these sewage, which requires the use of sewage pumps. The structure of the sewage pump is generally connected by screw locking during assembly, but because it will generate large vibrations during use, long-term use may cause loosening of the connected parts, which will affect the performance of the sewage pump. In normal use, in addition, the sealing performance of the screw-fastened connection method is relatively poor during ass...

Problems solved by technology

The structure of the sewage pump is generally connected by screw locking during assembly, but because it will generate large vibrations during use, long-term use may cause loosening of the connected parts, which will affect the performance of the sewage pump. In normal use, in addition, the tightness of the screw fastening connection method is relatively poor during assembly, and the overall structural stability is not high
