The working principle of centrifugal pumps is briefly summarized

First, the structure of the centrifugal pump
The main structure of the centrifugal pump includes: inlet, impeller, outlet, bearing and sealing device. Among them, the impeller is the core component of the centrifugal pump, which is composed of multiple vanes, usually in the shape of a curved or inclined plate.
Second, the working principle of centrifugal pump
Centrifugal pumps work by using centrifugal force to suck liquid from the inlet into the pump body, and then press it out of the pump port by turning the impeller. The specific workflow is as follows:
1. The liquid flows into the pump body from the inlet of the centrifugal pump, and the flow rate depends on the speed of the pump and the cross-sectional area of the inlet of the pump.
2. After entering the pump body, the liquid will be transported to the impeller and rotated rapidly by the blades of the impeller;
3. Due to the rapid rotation of the impeller, the liquid will be subjected to the outward centrifugal force, so as to be pressed towards the outlet of the pump;
4. Process 3 is constantly circulating, and the liquid is continuously pressed to the outlet with the rotation of the impeller, and finally pumped out of the centrifugal pump.
In general, centrifugal pumps work by converting motion energy into pressure energy, and the centrifugal force generated by the rapid rotation of the impeller presses the liquid towards the outlet of the pump.
