Description

Technical Field

[0001] The utility model belongs to the technical field of compressors, and in particular relates to a compressor oil separator and a rotor structure. Background Art

[0002] Lubricating oil plays an important role in the compressor, such as lubrication, sealing, cooling and noise reduction. Therefore, during the operation of the compressor, it is necessary to ensure that there is enough lubricating oil in the oil pool so that the lubricating oil exists in the gaps between various components in the compressor. By sealing various leakage channels, the leakage of refrigerant is reduced to ensure the volumetric efficiency and performance of the compressor.

[0003] However, during the operation of the compressor, the lubricating oil is easily carried out of the compressor by the refrigerant gas into the refrigeration system, which causes the oil pool level in the compressor to decrease and the oil supply to decrease, resulting in wear of the friction parts or even jamming and other phenomena such as inability to operate. In addition, the formation of an oil film blocks the air-conditioning pipeline, resulting in poor heat exchange efficiency and difficulty in ensuring the reliability of the compressor.

[0004] Based on the above problems, although an oil separator has appeared in the prior art, which is used to drive the oil separator to rotate through the rotor when the compressor is running, and blow the oil particles free on the upper part of the rotor to the surrounding area, thereby reducing the lubricating oil discharged from the compressor along with the refrigerant gas, but its effect is limited, and it is still difficult to ensure the oil storage amount inside the compressor and the performance of the compressor. Utility Model Content

[0005] In order to solve the deficiencies of the prior art, the utility model provides a compressor oil separator and a rotor structure, which achieves the purpose of reducing the discharge of lubricating oil from the inside of the compressor, effectively improving the circulation rate of the lubricating oil, and enhancing the performance of the compressor.

[0006] The technical purpose to be achieved by the utility model is achieved through the following technical solutions:

[0007] The utility model provides a compressor oil separator, comprising a base and an oil separator assembly, wherein the oil separator assembly at least comprises a first oil separator cylinder and a second oil separator cylinder, wherein the first oil separator cylinder is located inside the second oil separator cylinder, and the first oil separator cylinder and the second oil separator cylinder are both fixedly mounted on the base;

[0008] A plurality of first through holes are formed on the side wall of the first oil separator cylinder, and a plurality of second through holes are formed on the side wall of the second oil separator cylinder.

[0009] In some implementations, there is a gap between the side wall of the first oil separator cylinder and the side wall of the second oil separator cylinder, so that after the oil particles pass through the first through hole of the first oil separator cylinder, there is a larger space to form oil droplets through the second through hole of the second oil separator cylinder and flow back to the bottom of the compressor.

[0010] In some implementations, the first through hole and the second through hole are staggered to ensure that the oil particles are better formed into oil droplets, thereby flowing back to the bottom of the compressor.

[0011] In some implementations, the first through hole is circular, oval, square or semicircular;

[0012] The second through hole is circular, oval, square or semicircular. The shapes of the first through hole and the second through hole can be adjusted accordingly according to design and production requirements, which has the advantage of high flexibility.

[0013] In some implementations, a plurality of the first through holes are evenly distributed along the circumference of the first oil separator cylinder to ensure a uniform filtering effect on the oil particles.

[0014] In some implementations, a plurality of the second through holes are divided into at least two groups along the axial direction of the second oil separator cylinder, and a plurality of the second through holes in the same group are evenly distributed along the circumference of the second oil separator cylinder, ensuring a uniform filtering effect on the oil particles to form oil droplets that flow back to the bottom of the compressor.

[0015] In some implementations, a plurality of first connection holes for installation and fixation are provided on the base, so that the oil separator can be assembled in position through the plurality of first connection holes, thereby improving assembly efficiency and assembly accuracy.

[0016] In some implementations, the oil separator assembly is located in the middle of the base, and a plurality of the first connection holes are circumferentially spaced apart along the edge of the base to ensure installation stability and use stability of the oil separator.

[0017] The present application also provides a rotor structure, comprising a rotor body, a first counterweight, a second counterweight, and the oil separator described in any one of the above items;

[0018] The first counterweight block and the second counterweight block are respectively connected to the two ends of the rotor body, and the oil separator is connected to the first counterweight block, so that the oil separator can rotate with the rotor body to condense the oil particles, so that the oil particles form oil droplets and flow back to the bottom of the compressor.

[0019] In some implementations, a first connecting member and a second connecting member are respectively formed at both ends of the rotor body, the first connecting member is used to connect the first counterweight and the oil separator, and the second connecting member is used to connect the second counterweight, so as to facilitate the assembly of the first counterweight, the oil separator, the second counterweight and the rotor body, thereby improving the assembly efficiency and assembly accuracy.

[0020] In summary, the utility model has at least the following benefits:

[0021] 1. The compressor oil separator provided by the utility model comprises a first oil separator cylinder and a second oil separator cylinder with a double-layer structure, which can make the discharged refrigerant gas flow, and the oil particles contact with the first through hole on the first oil separator cylinder and the second through hole on the second oil separator cylinder to form oil droplets and return to the bottom of the compressor, effectively reducing the discharge of lubricating oil with the refrigerant gas, ensuring the oil storage amount inside the compressor, thereby improving the oil circulation rate;

[0033] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1 and Figure 2 A compressor oil separator is used in a compressor and rotates with the rotor. During the rotation, the oil particles free on the upper part of the rotor are formed into oil droplets and flow back to the bottom of the compressor.

[0037] The oil separator includes a base 100 and an oil separator assembly 200 . The base 100 is used for installing and fixing the oil separator assembly 200 and for installing and fixing the oil separator as a whole. For example, the base 100 is a plate-like structure, and the oil separator assembly 200 is fixedly arranged on a surface of the base 100 .

[0038] The oil separation assembly 200 includes at least a first oil separation cylinder 210 and a second oil separation cylinder 220. In this example, the oil separation assembly 200 adopts a double-layer structure, including a first oil separation cylinder 210 located in an inner layer and a second oil separation cylinder 220 located in an outer layer, that is, the first oil separation cylinder 210 is located inside the second oil separation cylinder 220, and the first oil separation cylinder 210 and the second oil separation cylinder 220 are both fixedly mounted on the base 100.

[0039] Specifically, the first oil separator cylinder 210 and the second oil separator cylinder 220 are both hollow cylindrical structures, and each includes two opposite openings, wherein an opening in the same direction of the first oil separator cylinder 210 and the second oil separator cylinder 220 is fixedly mounted on a surface of the base 100, so that the first oil separator cylinder 210, the second oil separator cylinder 220 establish a stable connection relationship with the base 100, which is convenient for the overall installation, fixation and use of the oil separator.

[0040] A plurality of first through holes 211 are formed on the side wall of the first oil separator cylinder 210 , and a plurality of second through holes 221 are formed on the side wall of the second oil separator cylinder 220 .

[0041] It can be known that the plurality of first through holes 211 can be evenly or unevenly spaced around the side wall of the first oil separator cylinder 210 , and the plurality of second through holes 221 can be evenly or unevenly spaced around the side wall of the second oil separator cylinder 220 .

[0042] In a specific application process, after the oil separator is connected to the rotor through the base 100, the oil separator can rotate with the rotor. During the rotation of the rotor, the oil particles free on the upper part of the rotor are blown to the periphery, and after being blocked and collected by the first oil separator cylinder 210, they enter the second oil separator cylinder 220 through a plurality of first through holes 211, and then after being blocked and collected by the second oil separator cylinder 220, they form oil droplets through a plurality of second through holes 221, and finally flow back to the bottom of the compressor, thereby reducing the discharge of lubricating oil from the inside of the compressor and effectively improving the circulation rate of the lubricating oil.

[0043] In some embodiments, there is a gap between the side wall of the first oil separator cylinder 210 and the side wall of the second oil separator cylinder 220, so that after the oil particles pass through the first through hole 211 of the first oil separator cylinder 210, there is a larger space to form oil droplets through the second through hole 221 of the second oil separator cylinder 220 and flow back to the bottom of the compressor.

[0044] For example, the side wall of the first oil separator cylinder 210 and the side wall of the second oil separator cylinder 220 are in a fitted state, and the oil particles free on the upper part of the rotor cannot be effectively formed into oil droplets, and it is difficult to reflect the actual function of the double-layer oil separator cylinder of the oil separator assembly 200.

[0045] When a gap is designed between the side wall of the first oil separator cylinder 210 and the side wall of the second oil separator cylinder 220, during the rotation of the rotor, the oil particles free on the upper part of the rotor are blown to the periphery, and after being blocked and collected by the first oil separator cylinder 210, enter the gap between the first oil separator cylinder 210 and the second oil separator cylinder 220. As the rotor continues to rotate, the oil particles located in the gap between the first oil separator cylinder 210 and the second oil separator cylinder 220 are blocked and collected by the second oil separator cylinder 220, and finally discharged as oil droplets through a plurality of second through holes 221 and flow back to the bottom of the compressor.

[0046] In some embodiments, the first through hole 211 and the second through hole 221 are staggered to ensure that the oil particles are better formed into oil droplets and flow back to the bottom of the compressor.

[0047] The first through hole 211 and the second through hole 221 are staggered, that is, any first through hole 211 is not aligned with any second through hole 221, so that when the oil particles on the upper part of the rotor enter the second oil separator cylinder 220 through the first through hole 211, they are not directly discharged from the second through hole 221, but continue to be blocked and collected by the second oil separator cylinder 220, and finally form oil droplets that are discharged from the second through hole 221.

[0048] In some embodiments, the first through hole 211 is circular, elliptical, square or semicircular; the second through hole 221 is circular, elliptical, square or semicircular. The shapes of the first through hole 211 and the second through hole 221 are adjusted accordingly in combination with design and production requirements, which has the advantage of strong flexibility.

[0049] like Figure 1 As shown, the first through hole 211 and the second through hole 221 are both circular structures. Figure 2 As shown, the first through hole 211 is a circular structure and the second through hole 221 is a square structure. Of course, the first through hole 211 can also be a semicircular structure and the second through hole 221 can be a circular structure, etc. This example does not limit the shape combination of the first through hole 211 and the second through hole 221, and can be adjusted according to actual needs.

[0050] In some embodiments, if the first through holes 211 are evenly distributed along the circumference of the first oil separator 210 , a uniform filtering effect on the oil particles is ensured.

[0051] The second through holes 221 are divided into at least two groups along the axial direction of the second oil separator cylinder 220. The second through holes 221 in the same group are evenly distributed along the circumference of the second oil separator cylinder 220 to ensure uniform filtering effect on oil particles, so as to form oil droplets to flow back to the bottom of the compressor.

[0052] For example, the plurality of second through holes 221 are divided into five groups along the axial direction of the second oil separator cylinder 220 , and the plurality of second through holes 221 in the same group are evenly distributed along the circumference of the second oil separator cylinder 220 .

[0053] The compressor oil separator provided by the utility model includes a first oil separator cylinder 210 and a second oil separator cylinder 220 with a double-layer structure, which can make the oil particles of the discharged refrigerant gas contact with the first through hole 211 on the first oil separator cylinder 210 and the second through hole 221 on the second oil separator cylinder 220 during the flow process to form oil droplets and return to the bottom of the compressor, effectively reducing the discharge of lubricating oil with the refrigerant gas, ensuring the oil storage amount inside the compressor, and thus improving the oil circulation rate.

[0054] Embodiment 2:

[0055] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the base 100 of the utility model, see Figure 3 .

[0056] The base 100 is provided with a plurality of first connection holes 110 for installation and fixation, so that the oil separator can be assembled in position through the plurality of first connection holes 110 , thereby improving assembly efficiency and assembly accuracy.

[0057] For example, a connector is provided on the rotor for passing through the first connecting hole 110, so that the connector is aligned with the first connecting hole 110 and connected, which facilitates the assembly of the rotor and the oil separator. Other locking members or riveting methods can also be used to ensure a stable connection between the rotor and the oil separator.

[0058] In some embodiments, the oil separator assembly 200 is located in the middle of the base 100, and a plurality of first connection holes 110 are circumferentially spaced apart along the edge of the base 100 to ensure the installation stability and use stability of the oil separator.

[0059] For example, the base 100 is a circular plate-like structure, the first oil separator cylinder 210 of the oil separator assembly 200 is located in the middle of the base 100, the second oil separator cylinder 220 is arranged outside the first oil separator cylinder 210, and is connected to the outward position of the middle of the base 100, and the first connecting hole 110 is located at the edge of the base 100. Here, the number of the first connecting holes 110 can be two, three, or more than three, etc., and there is no restriction on this in this example. For example, the number of the first connecting holes 110 is three, and the three first connecting holes 110 are evenly spaced circumferentially along the edge of the base 100 to ensure a stable and force-balanced installation effect for the oil separator.

[0064] In some embodiments, a first connecting member 310 and a second connecting member 320 are respectively formed at both ends of the rotor body 300. The first connecting member 310 is used to connect the first counterweight 400 and the oil separator, and the second connecting member 320 is used to connect the second counterweight 500, so as to facilitate the assembly of the first counterweight 400, the oil separator, the second counterweight 500 and the rotor body 300, thereby improving the assembly efficiency and assembly accuracy.
