Abstract

The invention discloses a water inlet / outlet section structure. The water inlet / outlet section structure comprises a water inlet / outlet section body which is of a split structure and comprises a water inlet / outlet section fixed body and a water inlet / outlet section movable connecting body. The water inlet / outlet section movable connecting body is movably connected with the water inlet / outlet section fixed body in a sealed mode through a sealing structure. According to the water inlet / outlet section structure, the number of types of water inlet / outlet sections is greatly decreased by designing the water inlet / outlet section body into a split structure with two parts, and universality of a water inlet / outlet section is achieved accordingly; errors of the mounting size can be well compensated; the inventory cost is lowered; and the site mounting and pipeline changing by a user are more convenient.

Description

Technical field [0001] The invention relates to the technical field of pumps, in particular to a water inlet and outlet section structure. Background technique [0002] The water inlet and outlet are the converging parts of the pump inlet and outlet pipelines, which are connected to the pipeline at the same time, one in and one out; the pump conveys liquid or pressurizes the liquid, and transfers the mechanical energy of the prime mover or other external energy to the liquid , Increase the liquid energy. The inlet and outlet section structure of the existing pump is an integral casting. The customer needs to make the pipeline according to the fixed size during on-site installation. When the pipeline installation error is small, a soft joint is used to compensate for the size error. The flange diameter of the installation size , The nominal pressure and implementation standards must be consistent, and the customer cannot change the installation interface method. As a result, the...
