1. The automobile water pump is installed on the engine block. It is generally a centrifugal water pump. It is mainly driven by the water pump belt and pulley, but the direct drive energy comes from the rotation of the generator, compressor, fan coupling, etc. of;

2. A water pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Water pumps are mainly used to transport liquids, including water, oil, acid and alkali liquids, emulsions, suspoemulsions and liquid metals, etc. They can also transport gas mixtures and liquids containing suspended solids;

3. According to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use changes in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and there are types such as centrifugal pumps, axial flow pumps and mixed flow pumps;
