The interface between the pipeline and the water pump is a flexible connector
Thread Content
As the title suggests, it is text from the Mechanical and Electrical Engineering section of the first-level constructor exam. I work in the field of process engineering. Normally, chemical process pumps don’t have flexible connections at their inlet and outlet ports. Do water pumps need flexible connections?
Generally, small pumps are not necessary; large pumps or those used with materials at high temperatures are required
First is to consider vibration, and second is ease of connection; flexible connections are easy to maintain and prevent leaks. Rigidity is different.
What kind of fittings are used for flexible connections? Rubber hose?
