Description

Technical Field

[0001] The utility model relates to the technical field of liquid pumps, in particular to a rotor injection mold for manufacturing a rotor type phase change liquid cooling pump. Background Art

[0002] A pump is a mechanical device that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] In the field of refrigerant transportation, volumetric pumps, rotor pumps or centrifugal pumps are traditionally used for refrigerant transportation. The rotor will wear out during continuous operation, which will not only cause metal powder to fall off and burn out the motor, but also conventional pumps require the presence of lubricating oil or lubricant during operation to reduce pump wear.
