Description

Technical Field

[0001] The utility model relates to a rotor pair for 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] The liquid pump is a key component in the refrigeration system. It is mainly used to suck the refrigerant from the evaporator, compress it, and then spray it into the condenser. Due to the different sizes of refrigeration systems, the design of the liquid pump needs to consider factors such as flow rate, pressure, and noise.

[0004] 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. At the same time, as the rotor rotates continuously, it will generate loud noise, affecting the normal use of the liquid pump and reducing its service life. Utility Model Content

[0005] The purpose of the utility model is to provide a technical solution for a rotor pair of a rotor-type phase change liquid cooling pump to address the deficiencies in the prior art, which can not only reduce the wear of the rotor pair during rotation, but also reduce the noise generated during rotation, thereby protecting the rotor pair and extending the service life of the rotor pair.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A rotor pair for a rotor-type phase-change liquid cooling pump, comprising

[0008] A pair of mutually meshing driving rotor and driven rotor;

[0009] Features:

[0010] Both the active rotor and the driven rotor include a metal body and an engineering plastic layer, the engineering plastic layer includes a first elastic layer and / or a second elastic layer, and the first elastic layer and / or the second elastic layer are wrapped around the outer surface of the metal body; through the design of the engineering plastic layer, not only can the wear of the rotor pair during rotation be reduced, but also the noise generated during rotation can be reduced, thereby protecting the rotor pair and extending the service life of the rotor pair.

[0011] Furthermore, the first elastic layer or the second elastic layer is integrally injection-molded and wrapped around the outer surface of the metal body. The integrally injection-molded first elastic layer or the second elastic layer can protect the metal body, and the processing and manufacturing are convenient and fast.

[0012] Furthermore, the first elastic layer and the second elastic layer are sequentially injection molded from the inside to the outside and wrapped around the outer surface of the metal body. By wrapping the first elastic layer and the second elastic layer of different materials on the outer surface of the metal body, the performance of the rotor pair can be greatly improved.

[0013] Furthermore, the first elastic layer and the second elastic layer are injection-molded in an interlaced manner and wrapped around the outer surface of the metal body. The design of the first elastic layer and the second elastic layer being injection-molded in an interlaced manner can greatly improve the bearing capacity and sealing of the rotor pair, thereby further improving the performance of the rotor pair.

[0014] Furthermore, the first elastic layer and / or the second elastic layer are both made of elastomeric materials, and the elastomeric materials can be selected from rubber, polyetheretherketone (PEEK), etc., preferably polyetheretherketone (PEEK). This material is non-conductive and has good affinity. Even if it is worn, it will not cause damage to the motor. At the same time, it can run dry. The refrigerant in the cooling system is easy to evaporate and volatilize to produce gas. The gas will exist in dry operation, which can meet the requirements of dry operation.

[0015] Furthermore, a groove is provided on the outer surface of the metal body, and the engineering plastic layer is connected to the metal body through the groove. Through the design of the groove, the contact area between the engineering plastic layer and the metal body can be increased, thereby improving the stability and reliability of the active rotor and the driven rotor during operation.

[0016] Furthermore, the thickness of the engineering plastic layer is 2 to 4 mm, which can reduce the manufacturing cost while ensuring the performance of the engineering plastic layer and the rotor pair.

[0017] Furthermore, the external teeth on the driving rotor and the driven rotor are both in a straight line or a curved line.

[0018] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0019] 1. The utility model can not only reduce the wear of the rotor pair during the rotation process, but also reduce the noise generated during the rotation process, play a role in protecting the rotor pair and prolonging the service life of the rotor pair.

[0020] 2. The first elastic layer or the second elastic layer formed by integral injection molding can protect the metal body, and the processing and manufacturing are convenient and fast.

[0021] 3. By wrapping the first elastic layer and the second elastic layer of different materials on the outer surface of the metal body, or by designing the first elastic layer and the second elastic layer by staggered injection molding, the bearing capacity and sealing of the rotor pair can be greatly improved, and the performance of the rotor pair can be further improved.

[0036] The first elastic layer or the second elastic layer is made of elastomeric material, and the elastomeric material can be selected from rubber, polyetheretherketone (peek), etc., preferably polyetheretherketone (peek). This material is non-conductive and has good affinity. Even if it is worn, it will not cause damage to the motor. At the same time, it can run dry.

[0037] Example 2

[0038] like Figure 1 and Figure 3 As shown, a rotor pair for a rotor-type phase-change liquid cooling pump of the utility model includes a pair of mutually meshing active rotors and driven rotors; the outer teeth on the active rotor and the driven rotor are both straight or curved. The present application preferably uses active rotors and driven rotors with curved outer teeth.

[0039] Both the active rotor and the driven rotor include a metal body and an engineering plastic layer. A groove is provided on the outer surface of the metal body, and the engineering plastic layer is connected to the metal body through the groove. The design of the groove can increase the contact area between the engineering plastic layer and the metal body, thereby improving the stability and reliability of the active rotor and the driven rotor during operation.

[0040] The thickness of the engineering plastic layer is 2 to 4 mm, which can reduce the manufacturing cost while ensuring the performance of the engineering plastic layer and the rotor pair.

[0041] The engineering plastic layer includes a first elastic layer and a second elastic layer, which are sequentially injection molded from the inside to the outside and wrapped on the outer surface of the metal body. By wrapping the first elastic layer and the second elastic layer of different materials on the outer surface of the metal body, the performance of the rotor pair can be greatly improved. Through the design of the engineering plastic layer, not only can the wear of the rotor pair during the rotation process be reduced, but also the noise generated during the rotation process can be reduced, which plays a role in protecting the rotor pair and extending the service life of the rotor pair.

[0042] The first elastic layer and the second elastic layer are both made of elastomeric materials. The elastomeric material can be selected from rubber, polyetheretherketone (PEEK), etc., preferably polyetheretherketone (PEEK). This material is non-conductive and has good affinity.

[0048] The engineering plastic layer includes a first elastic layer and a second elastic layer, which are injection-molded alternately and wrapped around the outer surface of the metal body. The design of the first elastic layer and the second elastic layer being injection-molded alternately can greatly improve the bearing capacity and sealing of the rotor pair, and further improve the performance of the rotor pair. The design of the engineering plastic layer can not only reduce the wear of the rotor pair during rotation, but also reduce the noise generated during rotation, play a role in protecting the rotor pair, and extend the service life of the rotor pair.

[0049] The first elastic layer and the second elastic layer are both made of elastomeric materials.
