Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, and specifically relates to an oil baffle assembly, rotor assembly and compressor for a compressor. Background Technology

[0002] The compressor contains multiple moving parts, such as pistons and crankshafts. These moving parts generate friction when operating at high speeds. Refrigeration oil, as a lubricant, forms an oil film between the moving parts to lubricate them and reduce the temperature of the pump body. Specifically, during compressor operation, as the crankshaft rotates, the refrigerant oil enters from the tail end of the crankshaft and reaches the top of the crankshaft along the spiral oil grooves on the crankshaft. Due to the preset offset between the crankshaft crank and the main end, the refrigerant oil is thrown out when the crankshaft rotates. Some of the thrown-out refrigerant oil is drawn into the pump body through the muffler intake port inside the compressor, and then rotated, compressed, and discharged into the refrigeration system along with the drawn-in gas. This not only reduces the stability of the refrigeration system but also leads to a decrease in cooling and lubrication due to the reduction in refrigerant oil.

[0003] Currently, oil baffles are usually installed inside the compressor to prevent refrigerant oil from being drawn into the pump body; however, existing oil baffles generally have an opening in the middle; in actual use, most of the oil-gas mixture is discharged directly after contacting the oil baffle, but some oil-gas mixture is still discharged through the opening, resulting in poor oil-gas separation effect, which easily leads to waste of refrigerant oil and thus affects the stability of the compressor.

[0031] The second oil baffle plate body 21 is provided with a plurality of second material holes 24, which are evenly arranged circumferentially on the second oil baffle plate body 21.

[0032] It should be noted that the position of the first feed hole 14 corresponds to the position of the second guide plate 23, so that the oil-gas mixture in the first feed hole 14 is diverted by the second guide plate 23, thereby allowing the oil-gas mixture entering between the first oil baffle 1 and the second oil baffle 2 to move a longer distance, and effectively separating the refrigeration oil in the oil-gas mixture.

[0033] The first side of the second oil baffle plate body 21 is provided with a plurality of positioning sleeves 25, which are parallel to the axis of the second oil baffle plate body 21 and are respectively provided with positioning holes 15. One end of the positioning sleeve 25 is connected to the second oil baffle plate body 21, and the other end of the positioning sleeve 25 passes through the positioning hole 15 and extends toward the end face of the compressor motor rotor.

[0035] In this embodiment 1, a light film 31 is provided on the inner wall surface of the cylindrical enclosure 3. By providing the light film 31 on the inner wall surface of the cylindrical enclosure 3, the cylindrical enclosure 5 is protected by the light film 31. Secondly, the smooth surface of the light film 31 can guide the flow of the refrigeration oil on the inner wall of the cylindrical enclosure 3, so that the refrigeration oil on the cylindrical enclosure 3 can be quickly collected.

[0036] The inner wall of the cylindrical enclosure 3 is also provided with an oil guide groove 32 so that the refrigeration oil on the cylindrical enclosure 3 flows into the oil guide groove 32, thereby realizing the collection and guidance of the refrigeration oil by the oil guide groove 32; wherein, the axis of the oil guide groove 32 is parallel to the axis of the cylindrical enclosure 3.

[0037] A cooling cavity 33 is provided inside the side wall of the cylindrical enclosure 3.

One end of the connecting valve 6 is connected to the first end of the cooling cavity 33, and the other end of the connecting valve 6 is used to connect to the outlet end of the compressor. By connecting the cooling cavity 33 to the outlet end of the compressor using the connecting valve 6, air can be supplied into the cooling cavity 33. The air flowing in the cooling cavity 33 cools the cylindrical enclosure 3, thereby dissipating heat from the first oil baffle 1 and the second oil baffle 2, and enabling better liquefaction and separation of the refrigerant oil in the oil-gas mixture.

[0038] Assembly principle: In the oil baffle assembly described in Embodiment 1, during assembly, the first oil baffle plate body 11 is positioned and installed on the compressor rotor through the first through hole 12, and the second oil baffle plate body 21 is positioned and installed on the compressor rotor through the second through hole 22, thereby achieving assembly between the first oil baffle plate 1, the second oil baffle plate 2 and the compressor rotor; the positioning sleeve 25 of the second oil baffle plate 2 is aligned with the positioning hole 15 of the first oil baffle plate 1, so that the positioning sleeve 25 is inserted into the positioning hole 11, so that the first oil baffle plate 1 and the second oil baffle plate 2 are positioned and connected through the positioning hole 15 and the positioning sleeve 25; next, by installing fixing bolts in the positioning sleeve 25, the first oil baffle plate 1, the second oil baffle plate 2 and the compressor motor rotor are fixed by the positioning sleeve 25 and the fixing bolts; the cylindrical enclosure 3 is coaxially assembled inside the compressor, and the cylindrical enclosure 3 is pressed against the compressor motor stator, thereby achieving the fixing of the cylindrical enclosure 3.

[0039] Working principle and oil blocking process: In the oil baffle assembly described in Embodiment 1, during operation, the oil-gas mixture in the compressor enters the first oil baffle plate 1. The first oil baffle plate body 11 and the first guide plate 13 perform preliminary liquefaction of the refrigerant oil in the oil-gas mixture. The preliminarily liquefied oil-gas mixture then enters the space between the first oil baffle plate 1 and the second oil baffle plate 2 through the first feed hole 14. Next, the second oil baffle plate 2 performs secondary liquefaction of the refrigerant oil in the oil-gas mixture. The gas flow after oil-gas separation is discharged through the second feed hole 24. The process of secondary liquefaction of the refrigerant oil in the oil-gas mixture by the second oil baffle plate 2 is basically the same as that of the first oil baffle plate 1, and will not be described again here.

[0040] It should be noted that when the compressor motor rotor rotates, the positioning sleeve 25 drives the first oil baffle 1 and the second oil baffle 2 to rotate synchronously with the compressor rotor. While the refrigerant oil in the oil-gas mixture is liquefied through the first oil baffle 1 and the second oil baffle 2, the first oil baffle 1 and the second oil baffle 2 rotate with the compressor rotor. Through the rotation of the first oil baffle 1 and the second oil baffle 2, the refrigerant oil on the first oil baffle 1 and the second oil baffle 2 is thrown onto the cylindrical enclosure 3 under the action of centrifugal force. Based on the smooth performance of the surface of the light film 31, the refrigerant oil on the cylindrical enclosure 3 is guided, so that the refrigerant oil on the cylindrical enclosure 3 flows into the oil guide groove 32, and then the refrigerant oil is collected and guided through the oil guide groove 32.

[0041] It should also be noted that while the first oil baffle 1 and the second oil baffle 2 rotate, the first guide plate 13 and the second guide plate 23 turbulent the oil-gas mixture, increasing the flow distance of the oil-gas mixture. This allows for better liquefaction of the refrigerant oil in the oil-gas mixture, effectively improving the efficiency of oil-gas separation, reducing refrigerant oil loss, and ensuring the normal operation and service life of the compressor. The first guide plate 13 and the second guide plate 23 also guide the liquefied refrigerant oil, facilitating better collection and effectively improving the efficiency and effectiveness of refrigerant oil liquefaction and collection. Secondly, the compressor delivers air into the cooling cavity 33 through the connecting valve 6. The air flowing within the cooling cavity 33 cools the cylindrical enclosure 3, thereby dissipating heat from the first oil baffle 1 and the second oil baffle 2, further enhancing the liquefaction and separation of the refrigerant oil in the oil-gas mixture.

[0042] In this embodiment 1, both the first oil baffle body 11 and the second oil baffle body 21 are disc-shaped. Both the first oil baffle body 11 and the second oil baffle body 21 have through holes at their center positions. The first oil baffle 1 and the second oil baffle 2 are positioned and installed on the compressor rotor through the through holes. The first oil baffle body 11 and the second oil baffle body 21 are provided with sliding grooves on their circumferential sides and mounting seats are provided in the sliding grooves. The mounting seats and sliding grooves form a sliding assembly, so that the cylindrical enclosure 3 slides through the outside of the first oil baffle 1 and the second oil baffle 2.

[0043] In this embodiment 1, the first oil baffle body 11 and the second oil baffle body 21 are arranged parallel to each other at intervals. The first oil baffle body 11 has a first guide plate 13 arranged at equal angles on the side away from the second oil baffle body 21, and the second oil baffle body 21 has a second guide plate 23 arranged at equal angles on the side close to the first oil baffle body 11, and the second guide plate 23 is connected to the first oil baffle body 11; wherein, a first included angle is preset between the first guide plate 13 and the radial direction of the first oil baffle body 11, and the second guide plate 23 and the second oil baffle body 21 are arranged at equal angles. A second included angle is preset between the radial directions of the body 21; that is, the first guide plate 13 and the second guide plate 23 are both inclined, and the second guide plate 23 corresponds to the first feed hole 14. The inclined first guide plate 13 and the second guide plate 23 can better guide the liquefied refrigeration oil. Specifically, the second guide plate 23 diverts the oil-gas mixture in the first feed hole 14, so that the oil-gas mixture entering between the first oil baffle plate 1 and the second oil baffle plate 2 can move a longer distance, and the refrigeration oil in the oil-gas mixture can be effectively separated.

[0044] In this embodiment 1, positioning holes 25 are set at equal angles on the first oil baffle plate body 11, and positioning sleeves 25 are set at equal angles on the second oil baffle plate body 21. Positioning sleeves 12 are set through the positioning holes 15. The first oil baffle plate 1 and the second oil baffle plate 2 are positioned and connected through the positioning holes 15 and the positioning sleeves 25. Fixing bolts are set in the positioning sleeves 25 to fix the second oil baffle plate 2 to the compressor motor rotor, and to connect the first oil baffle plate 1 and the second oil baffle plate 2, so that the first oil baffle plate 1 and the second oil baffle plate 2 can rotate with the compressor rotor.

[0045] Example 2 This embodiment 2 provides a rotor assembly, including a rotor body and an oil baffle assembly disposed on the rotor body; wherein, the oil baffle assembly is the oil baffle assembly for a compressor described in embodiment 1; it should be noted that the assembly relationship between the rotor body and the oil baffle assembly is as described in embodiment 1 above, and will not be repeated here.

[0046] Example 3 This embodiment 3 provides a compressor, including the rotor assembly described in embodiment 2 above. It should be noted that the compressor is basically the same as the existing compressor in terms of structure and principle. The difference is that the rotor assembly in the existing compressor is replaced with the rotor assembly described in embodiment 2. All other aspects are the same, and the specific structure will not be described here.

[0047] The oil baffle assembly for compressors described in this invention disperses and guides the oil-gas mixture through a first oil baffle plate body, a second oil baffle plate body, a first feed hole, a second feed hole, a first guide plate, and a second guide plate. This effectively improves the efficiency and effect of oil-gas separation, reduces the loss of refrigerant oil, and ensures the normal operation and service life of the compressor. Specifically, the first and second oil baffle plates provide two-stage dispersion and turbulence for the oil-gas mixture, allowing for better separation of the oil-gas mixture on the first and second oil baffle plates, effectively improving the efficiency of oil-gas separation and reducing the loss of refrigerant oil. This system minimizes oil loss, ensuring the compressor's normal operation and lifespan. The first and second guide plates guide the liquefied refrigerant oil, facilitating better collection and improving efficiency. Furthermore, the compressor, through connecting valves, creates airflow within the cooling cavity, dissipating heat from the cylindrical enclosure, first oil baffle, and second oil baffle. This lowers the pressure on the cylindrical enclosure, first oil baffle, and second oil baffle, allowing for better liquefaction and separation of the refrigerant oil in the oil-gas mixture. This significantly improves oil-gas separation efficiency and reduces refrigerant oil waste.
