How the centrifugal pump works
How the centrifugal pump works As shown in Figure 2-6, fill the pump body and inlet pipe with water before starting, and completely drain the air. When the impeller rotates in the pump body, the water smashes to the outer edge under the action of centrifugal force, and then enters the outlet pipe through the vortex chamber and the diffuser tube. After the water is pumped out, a certain vacuum is formed at the inlet of the impeller, causing the pressure at this point to be less than atmospheric pressure. Due to the atmospheric pressure acting on the water surface, the pressure at the inlet of the impeller is greater. In this way, the water from the water source flows into the impeller through the inlet pipe. The impeller rotates continuously, the water continually smashes out, and the water from the water source is continuously replenished, forming a continuous water-lifting process. This is how the centrifugal pump works.
