Description

Technical Field

[0001] The present disclosure belongs to the technical field of compressors, and particularly relates to a vane lubrication structure and a compressor. Background Art

[0002] Rotary compressors, scroll compressors, etc. are widely used as air-conditioning compression mechanisms because of their advantages such as simple structure, small volume, excellent performance, high stability, and few reciprocating moving parts. However, there are many friction pairs inside the compressor. For a rotary compressor, such as the vane and the vane slot, the roller, the upper and lower flange end covers, the roller and the upper and lower flange end covers, the crankshaft and the roller, the upper and lower flange end covers, etc., many friction pairs are extremely likely to cause frictional wear and clearance leakage between the mating end faces, which become important factors affecting the performance and reliability of the compressor.

[0003] The wear of the vane and the vane slot, and the vane and the flange end face is a form of frictional loss with a relatively high proportion in the rotor compressor. Different from the bearing system, the friction pairs of the vane and the vane slot, and the vane and the flange end face do not have a stable oil supply method. On the one hand, when the oil level in the oil sump inside the compressor housing is higher than the cylinder, the vane is lubricated by being immersed in the oil sump. On the other hand, it is lubricated by the lubricating oil that returns from the liquid separator to the working chamber of the compressor. When the oil level in the compressor housing is low and the oil storage capacity of the liquid separator is small, the above two lubrication forms cannot lubricate reliably, resulting in dry friction of the vane and its friction pairs, a decrease in the performance of the pump body, and a relatively high reliability risk at the same time. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present disclosure is the insufficient lubrication between the vane and the vane slot, resulting in wear, so as to provide a vane lubrication structure, a compressor, and a refrigeration device.

[0029] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in combination with the specific embodiments of the present disclosure and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0030] Combination Figures 1 to 5 As shown, the embodiment of the present disclosure provides a vane lubrication structure, including: an oil supply channel 3, an oil pump assembly 4, one end of the oil supply channel 3 is connected to the bottom oil pool 5 of the compressor, and the other end is connected to the vane groove 2, and the oil pump assembly 4 is constructed to be driven by the exhaust airflow of the pump body assembly 22 of the compressor to pump the lubricating oil in the bottom oil pool 5 along the oil supply channel 3 into the vane groove 2.

[0031] The vane lubrication structure of the disclosed embodiment is provided with an oil supply channel 3 inside the compressor for supplying oil from the bottom oil pool 5 to the vane groove 2, and on this basis, an oil pump assembly 4 is added to improve the oil supply capacity of the oil supply channel 3, and the high-speed airflow discharged from the pump body assembly 22 of the compressor is used to provide driving force for the oil pump assembly 4, and the oil pumping mechanism pumps the lubricating oil at the bottom of the compressor into the vane groove 2 opened on the cylinder of the compression mechanism, thereby realizing lubrication and oil supply to the vane 1, ensuring that the vane 1 is always in a good lubrication state, which is beneficial to improving the operating stability and reliability of the compressor.

[0032] In some embodiments, the oil pump assembly 4 includes a driving impeller 6, which is disposed on one side of the exhaust port 7 of the pump body assembly 22, and is configured to be driven to rotate by the airflow of the exhaust port 7. Preferably, the driving impeller 6 includes an impeller shaft 19, and at least one blade 15 is disposed on the impeller shaft 19, and the at least one blade 15 is configured to face the airflow direction of the exhaust port 7, and can be blown by the exhaust airflow of the exhaust port 7, so that it drives the impeller shaft 19 to rotate.

[0033] The sliding vane lubrication structure of this embodiment utilizes the high-speed exhaust air flow of the pump body assembly 22 to drive the movement of the oil pump assembly 4. In order to obtain the rotational torque for the operation of the oil pump assembly 4, a drive impeller 6 device is adopted in this embodiment. The high-speed air flow blows the drive impeller 6 to rotate at a high speed, thereby driving the oil pump assembly 4 to rotate and realizing oil pumping.

[0034] The opening positions of the exhaust port 7 of the pump body assembly 22 of existing compressors are generally divided into two categories: upper exhaust and side exhaust. The embodiment of the present disclosure is directed to a compressor with side exhaust. The drive impeller 6 is shaped similar to a centrifugal fan, and multiple blades 15 are vertically arranged on the impeller shaft 19 along the axial direction. The high-speed air flow blows onto the blades 15 in a direction perpendicular to the axial direction, driving the drive impeller 6 to rotate at a high speed. If it is a compressor with upper exhaust, the drive impeller 6 is shaped similar to an axial flow fan, and multiple blades 15 have a preset angle with the axial direction. The high-speed air flow blows onto the blades 15 in a direction parallel to the axial direction, pushing the drive impeller 6 to rotate and realizing rotational oil pumping. The opening position of the exhaust port 7 of the compressor only affects the shape of the blades 15. Regardless of the exhaust form, ultimately, it is based on the compressor exhaust to drive the oil pump assembly 4 to pump oil.

[0035] In some embodiments, since the high-speed air flow discharged from the pump body assembly 22 is a mixed gas of refrigerant and lubricating oil, and the content of lubricating oil highly affects the oil discharge index of the compressor, the lower the oil discharge, the better. Therefore, the blades 15 are further configured to be able to adsorb the lubricating oil liquid in the air flow discharged from the exhaust port 7, realizing oil-gas separation. When the high-speed mixed gas collides with the blades 15, part of the lubricating oil will directly adhere to the surface of the blades 15, reducing the oil content in the mixed gas, realizing the separation of part of the lubricating oil and the refrigerant, reducing the oil discharge of the compressor, reducing the amount of lubricating oil entering the system, and improving the heat exchange efficiency of the evaporator and condenser.

[0036] At the same time, after the lubricating oil adheres to the blades 15 to a certain extent, it will detach from the blades 15 under the action of centrifugal force and return to the bottom oil sump 5 of the compressor. Preferably, measures such as adding an oil-repellent coating to the surface of the blades 15 can also be taken to reduce the adhesion of lubrication and accelerate the circulation efficiency of the lubricating oil.

[0037] Furthermore, since the oil pump assembly 4 absorbs part of the kinetic energy of the high-speed air flow, it can also play a role in stabilizing the exhaust air flow rate.

[0038] In some embodiments, the oil supply channel 3 includes a first channel 10 and a second channel 11. The first channel 10 is arranged along the axial direction of the pump body assembly 22, the second channel 11 is arranged along a direction perpendicular to the axial direction of the pump body assembly 22. The first end of the first channel 10 is communicated with the bottom oil sump 5, the first end of the second channel 11 is communicated with the sliding vane groove 2, and the second end of the first channel 10 is communicated with the second end of the second channel 11.

[0039] In this embodiment, the lubricating oil in the bottom oil sump 5 is conveyed to the vane groove 2 through the oil supply passage 3. The oil supply passage 3 is divided into two sections. The first section is the first passage 10 that sequentially penetrates the lower flange 21 and the cylinder block 14 along the axial direction of the pump body assembly 22. The first passage 10 communicates with the bottom oil sump 5 downward and communicates with the lower end face of the lower flange 21 upward. The second section is the second passage 11 that communicates with the first passage 10 and the vane groove 2 in the horizontal direction.

[0040] Furthermore, the pump body assembly 22 includes a cylinder block 14. The vane groove 2 is formed in the cylinder block 14. The second passage 11 is formed in the end face of the cylinder block 14 away from the bottom oil sump 5. The first end of the second passage 11 communicates with the end face of the vane groove 2 away from the bottom oil sump 5. Thus, the processing difficulty of the second passage 11 in this embodiment is greatly reduced. At the same time, the connection between the second passage 11 and the vane groove 2 is above the gravity direction, and the lubricating oil can just flow into the vane groove 2 under the action of gravity, which is beneficial to improving the lubrication effect of the vane 1. Preferably, the second passage 11 communicates with the middle part of the vane groove 2 in the radial direction, so as to realize uniform lubrication before and after the movement direction of the vane 1.

[0041] In some embodiments, the oil pump assembly 4 further includes a suction pipe 9. The suction pipe 9 is coaxially connected with the drive impeller 6. The suction pipe 9 is arranged in the first passage 10. The end of the suction pipe 9 corresponding to the first end of the first passage 10 extends out of the first passage 10 and extends below the liquid level of the bottom oil sump 5 or below the lower end face of the pump body assembly 22. The end of the suction pipe 9 corresponding to the second end of the first passage 10 is provided with an oil outlet hole 12, and the oil outlet hole 12 is configured to allow the lubricating oil inside the suction pipe 9 to flow into the second passage 11.

[0042] In the vane lubrication structure of this embodiment, the suction pipe 9 is arranged in the oil supply passage 3. The lower end of the suction pipe 9 extends out of the lower flange 21 and directly extends into the bottom oil sump 5, and the upper end reaches the second passage 11 directly. The suction pipe 9 is coaxially connected with the drive impeller 6. The rotation of the drive impeller 6 can drive the suction pipe 9 to rotate. The suction pipe 9 can use the internal oil guiding vane 13, threaded oil groove and other structures to draw oil upward to achieve the purpose of pumping oil. At the same time, since the suction pipe 9 can directly extend into the bottom oil sump 5, the vane 1 can be supplied with oil at different oil levels, ensuring that the vane 1 is always in a good lubrication state.

[0043] Preferably, an annular oil groove 17 is provided on the pump body assembly 22 corresponding to the oil outlet hole 12. The oil outlet hole 12 is communicated with the second channel 11 through the annular oil groove 17. The annular oil groove 17 can ensure that the oil outlet hole 12 is always communicated with the second channel 11 during the rotation of the oil suction pipe 9, so as to improve the ability of the oil pump assembly 4 to continuously supply lubricating oil to the lubricating surface in the sliding vane groove.

[0044] Preferably, a spiral oil groove is provided on the inner wall of the oil suction pipe 9. The spiral oil groove is communicated with the oil outlet hole 12. The oil suction pipe 9 is configured to supply oil to the oil outlet hole 12 spirally through the spiral oil groove during rotation, thereby providing an optional oil pumping method.

[0045] In another preferred embodiment, the oil guide vane 13 is fixedly arranged axially in the oil suction pipe 9 and is configured to rotate coaxially with the oil suction pipe 9. During the rotation of the oil guide vane 13 with the oil suction pipe 9, due to its special spiral structure, the oil pumping capacity of the oil pump assembly 4 can be greatly improved.

[0046] In some embodiments, the oil pump assembly 4 further includes an oil guide vane 13. The oil guide vane 13 is arranged in the oil supply channel 3. The oil guide vane 13 is power-connected to the driving impeller 6 and is configured to rotate with the driving impeller 6 to pump the lubricating oil in the bottom oil sump 5 along the oil supply channel 3 to the sliding vane groove 2.

[0047] In this embodiment, the oil guide vane 13 is arranged in the oil supply channel 3. The upper end of the oil guide vane 13 is power-connected to the driving impeller 6. The oil guide vane 13 can rotate with the driving impeller 6 in the oil supply channel 3 to pump the lubricating oil to the second channel 11 and further transport it to the friction part in the sliding vane groove 2 for lubrication.

[0048] In some embodiments, in order to axially limit the oil pump assembly 4 mainly composed of the driving impeller 6 and the oil suction pipe 9, a stepped thrust surface 16 is further provided on the impeller shaft 19. The impeller shaft 19 is rotationally assembled on the pump body assembly 22 through the stepped thrust surface 16. Preferably, a bearing can be arranged on the rotating plane. The bearing can be a sliding bearing, a rolling bearing, etc. to improve the rotating performance of the oil pump assembly 4. The design of the stepped thrust surface 16 can also improve the rotating stability of the oil pump assembly 4 and the oil pumping performance of the oil pump assembly 4.

[0049] Preferably, in the side-exhaust compressor, the oil pump assembly 4 is subject to radial forces perpendicular and axial to it. The stepped thrust surface 16 is arranged on the mating surface of the upper flange 20 and the cylinder block 14, which can reduce the processing difficulty and further improve the stability of the oil pump assembly 4. In the up-exhaust compressor, the oil pump assembly 4 is subject to an upward axial force, and the stepped thrust surface 16 is arranged on the mating surface of the lower flange 21 and the cylinder block 14 to improve the rotational stability of the oil pump assembly 4.

[0050] The embodiment of the present disclosure also provides a compressor, including the above-mentioned sliding vane lubrication structure. The pump body assembly 22 includes a silencing structure 18, and the exhaust port 7 is arranged on the silencing structure 18.

[0051] The compressor includes a pump body assembly 22, a motor stator and rotor arranged in a housing, and a bottom oil sump 5 located at the bottom of the housing. Lubricating oil is stored in the bottom oil sump 5. The pump body assembly 22 includes a cylinder block 14, rollers, a crankshaft for driving the rollers to rotate, an upper flange 20 and a lower flange 21 for supporting the crankshaft, and a sliding vane 1 for isolating the high-pressure and low-pressure chambers of the working chamber. A sliding vane groove 2 for the reciprocating movement of the sliding vane 1 is formed in the cylinder block 14. The sliding vane 1 and the sliding vane groove 2 are lubricated by the sliding vane lubrication structure, and the sliding vane 1 is always in a good lubricated state, greatly reducing the risk of wear of the sliding vane 1 at low liquid levels, which has an obvious effect on the high-load working state of the compressor and significantly improves the reliability of the compressor under harsh working conditions such as low lubricating oil levels.

[0052] In some embodiments, side exhaust is adopted. The exhaust port 7 is arranged in the radial direction of the pump body assembly 22 along the silencing structure 18, and the airflow of the exhaust port 7 blows out along the radial direction of the pump body assembly 22. The high-speed airflow blows laterally towards the drive impeller 6, causing it to drive the oil pump assembly 4 to rotate and operate, and cooperating with the oil suction pipe 9 and the oil guiding vane 13 to pump the lubricating oil in the bottom oil sump 5 into the sliding vane groove 2.

[0053] The sliding vane lubrication structure and the compressor with it proposed by the present invention not only achieve the purpose of reducing the oil discharge of the compressor, but also ensure that the friction pair between the sliding vane 1 and the sliding vane groove 2 is in a good lubricated state when the bottom lubricating oil of the compressor is at a low liquid level, greatly reducing the risk of wear of the sliding vane 1 at low liquid levels, which has an obvious effect on the high-load working state of the compressor and significantly improves the reliability of the compressor under harsh working conditions such as low lubricating oil levels.

[0054] A refrigeration device includes the above-mentioned sliding vane lubrication structure or the above-mentioned compressor.

[0055] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0056] The above are only the preferred embodiments of the present disclosure, and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure. The above is only the preferred implementation manner of the present disclosure. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present disclosure, several improvements and variations can be made, and these improvements and variations should also be regarded as the protection scope of the present disclosure.
