Regarding the size of the inlet and outlet of centrifugal pumps
Thread Content
Most centrifugal pumps have a large inlet and a small outlet; however, some pumps have the same size for both the inlet and outlet. Today I encountered a pump with a large outlet and a small inlet; I don’t understand why the designer chose such a design. This pump also features axial suction and radial discharge. What is the reason for this design? I seek an expert’s explanation
Look at the properties of the medium! and process requirements
Could you be more specific? For example, in what types of operating conditions is such a design necessary
Is the pump’s head low? The outlet pressure is not high.
Well, the traffic is high while Yang Cheng’s score is low. 450 cubic meters, 6 meters
The impeller is an open-type impeller; it seems to have a crushing function. The key lies in the properties of the medium. The medium contains solids and fibrous materials. The inlet is designed for concentrated crushing, while the outlet is enlarged to facilitate discharge, preventing the medium from accumulating and aggregating at the small outlet and thus blocking it.
Are there pumps of the same model that are designed with equal-sized inlet and outlet ports? Does that mean this is the only model that has such a design?
It is not an open impeller; rather, it features a closed impeller combined with an inducer design, offering high flow rates. The inlet pressure is low, and the net positive suction head available is insufficient, so the inlet size was reduced and an inducer was added.
I’m afraid to ask, but which standard specifies this? Learn* it. . . .
