Description

Technical Field

[0001] The utility model discloses a water pump coating which is resistant to high temperature and impact and has a long service life and belongs to the field of water pumps. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. It can also transport liquids, gas mixtures and liquids containing suspended solids. The technical parameters of water pump performance include flow rate, suction head, head, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric water pumps, vane pumps and other types. The surface of the water pump needs to be coated with paint to prevent the water pump from rusting and damage.

[0003] The existing coatings on the surface of water pumps have poor corrosion resistance and wear resistance. After long-term use, the internal surface of the water pump will be damaged due to long-term wear, which will affect the subsequent use of the water pump. In addition, traditional coatings have poor high temperature resistance. Utility Model Content
