Question regarding the pump location and motor location
Thread Content
I would like to ask the teachers: when referring to the front and back of a pump impeller, as well as the front and back bearings of the pump and those of the motor, from which direction is the \"front\" and \"back\" determined? Thank you!
Generally, it is divided into front and back in the direction from the pump inlet outward
Use the pump’s suction inlet as a reference to determine the front and back as asked in the question.
Of course, it is viewed from the pump’s suction inlet; nowadays, new types of water pumps rarely have two bearings – only cantilevered pumps come equipped with bearings. As for the motor, it goes without saying that one end extending from the motor shaft is the front end.
