What are the components of pump?

Pumps are divided into positive displacement pumps and vane pumps. A water pump is a machine that delivers or pressurizes a liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, and increases the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal, and also to transport liquids and gas mixtures. And a liquid containing suspended solids. The technical parameters for measuring the performance of the pump include flow, suction stroke, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volume pump and vane pump. The volumetric pump uses its change in the volume of the working chamber to transfer energy. The vane pump uses the interaction of the rotating blades and water to transfer energy. There are centrifugal pump, axial flow pump and mixed flow pump.1. Positive displacement pump: The liquid is delivered by the change of the working chamber volume period.2. Vane pump: the use of blade and liquid interaction to transport liquid.
