Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a support assembly and a compressor having the same. Background Art

[0002] At present, the scroll compressor in the prior art is widely used in the fields of refrigeration, air conditioning and heat pumps due to its high efficiency, small size, light weight and stable operation. An upper thrust or lower thrust structure is usually used to axially limit the crankshaft assembly during the operation of the compressor. In the lower thrust structure, the tail of the crankshaft structure is in direct contact with the lower thrust structure. In this way, during the long-term rotation of the crankshaft structure, the contact surface of the lower thrust structure will inevitably be worn, and a certain amount of wear debris will remain in the cavity between the lower bracket and the lower thrust structure.

[0003] However, during the long-term operation of the scroll compressor, this part of the wear debris will enter the filter and accumulate inside the filter. In the long run, this part of the wear debris will be re-sucked into the oil pump, causing a certain blockage in the internal channel of the oil pump and affecting the normal operation of the oil pump gear, ultimately affecting the normal operation of the oil pump, the oil pumping efficiency and the long-term reliability of the compressor.

[0067] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0068] like Figures 1 to 9 As shown, the first embodiment of the present invention provides a support assembly, which includes: a support seat 10, a filter 20, a stopper 30, a crankshaft structure 40 and a hydraulic pump 50 located in a filter chamber 21, which are connected to each other. The support seat 10 is provided with an avoidance through hole 11, and the filter 20 and the support seat 10 form a filter chamber 21. The stopper 30 is fixed to the bottom of the support seat 10, a part of the crankshaft structure 40 is rotatably arranged in the avoidance through hole 11 and supported on the stopper 30, an oil through hole 31 is arranged on the stopper 30, and another part of the crankshaft structure 40 is penetrated at the oil through hole 31 and connected to the hydraulic pump 50; an oil inlet channel 61 is provided between the hole wall of the oil through hole 31 and another part of the crankshaft structure 40, and a connecting channel 62 connected with the oil inlet channel 61 is provided between the stopper 30 and a part of the crankshaft structure 40. The support seat 10 is provided with an oil passage 63 , an oil inlet end of the oil passage 63 is connected with the connecting passage 62 , and an oil outlet end of the oil passage 63 is located outside the filter cavity 21 .

[0069] The support assembly provided in this embodiment is provided with an oil inlet channel 61, a connecting channel 62 and an oil outlet channel 63, so that the negative pressure generated by the hydraulic pump 50 during operation first sucks the lubricating oil into the oil hole 31, that is, into the oil inlet channel 61, then sucks it into the connecting channel 62, and finally sucks it into the oil outlet channel 63. When the crankshaft structure 40 moves relative to the stopper 30 and wear debris is generated due to friction, the lubricating oil will take away the wear debris at the connecting channel 62 when flowing through the connecting channel 62, and send the wear debris at the connecting channel 62 out of the filter chamber 21 through the oil outlet channel 63, thereby avoiding the situation where a large amount of wear debris remains in the filter chamber 21 and is easily sucked into the hydraulic pump 50, thereby better avoiding the impact on the normal operation of the hydraulic pump 50. Therefore, the support assembly provided by the present invention can solve the technical problem in the prior art that the wear debris generated by wear at the tail of the crankshaft structure 40 is easily sucked into the oil pump.

[0070] Specifically, the portion of the crankshaft structure 40 that contacts the stopper 30 is generally made of metal material, and the corresponding wear debris is metal debris. Specifically, the portion of the crankshaft structure 40 that contacts the stopper 30 is generally made of iron-containing material, and the corresponding wear debris is iron debris. Specifically, the filter element 20 includes a filter screen, and the hydraulic pump 50 can be an oil pump.

[0071] In this embodiment, the stopper 30 has a support surface 32 for supporting a part of the crankshaft structure 40, a part of the crankshaft structure 40 has a contact surface for contacting the support surface 32, and the connecting channel 62 includes a first oil running groove 621. The first oil running groove 621 is provided on the support surface 32 and / or the contact surface. With such a setting, it is convenient to effectively run the oil through the first oil running groove 621, and it is also convenient to collect the wear debris generated by the friction of the contact surface with respect to the support surface 32 through the oil running groove, so that the wear debris can be smoothly taken away when the lubricating oil flows through the first oil running groove 621, so that the wear debris flows into the outside of the filter chamber 21.

[0072] Specifically, when both the support surface 32 and the contact surface are provided with the first oil groove 621, the first oil groove 621 on the support surface 32 can be arranged opposite to the first oil groove 621 on the contact surface. Specifically, at least part of the first oil groove 621 is located between the support surface 32 and the contact surface.

[0073] Specifically, the first oil groove 621 extends radially along the oil hole 31, and there are a plurality of first oil grooves 621, which are arranged at intervals in the circumferential direction of the oil hole 31; the connecting channel 62 also includes a second oil groove 622, and the second oil groove 622 is arranged on the supporting surface 32, and the plurality of first oil grooves 621 are all connected to the second oil groove 622, and the oil inlet end of the oil channel 63 is connected to the second oil groove 622. With such a structural arrangement, the plurality of first oil grooves 621 can better collect the wear debris generated by the friction between the crankshaft structure 40 and the stopper 30, and the wear debris collected by the plurality of first oil grooves 621 is transferred to the second oil groove 622 through lubricating oil, and then the lubricating oil at the second oil groove 622 carries the wear debris into the oil channel 63, and the lubricating liquid carries the wear debris and is discharged to the outside of the filter cavity 21 through the oil channel 63. In addition, this multi-path lubricating oil circulation design not only improves the circulation efficiency of the lubricating oil, but also increases the circulation path of the lubricating oil, making the distribution of the lubricating oil more uniform, and facilitating better use of the lubricating oil to fully remove the wear debris from the filter chamber 21, thereby avoiding the influence of the wear debris on the operation of the hydraulic pump 50, thereby improving the operating stability and efficiency of the compressor.

[0074] Specifically, the oil inlet end of the oil passage 63 may be arranged opposite to at least a portion of the second oil passage groove 622 , and the oil inlet end of the oil passage 63 is located above the second oil passage groove 622 .

[0075] Specifically, along the extension direction from the bottom of the first oil groove 621 to the notch of the first oil groove 621, the flow cross section of the first oil groove 621 gradually increases. With such a structural setting, it is possible for the wear debris generated by the friction between the crankshaft structure 40 and the stopper 30 to smoothly enter the first oil groove 621, thereby avoiding the situation where the wear debris cannot smoothly enter due to the small flow cross section at the notch of the first oil groove 621. In addition, the setting of the above structure can also avoid the situation where the corresponding structure is too hollowed out due to the excessive groove volume of the first oil groove 621, resulting in insufficient structural strength. This gradual flow cross section design can effectively reduce the resistance of the lubricating oil during the circulation process and increase the circulation speed of the lubricating oil.

[0076] Specifically, “the flow cross-section of the first oil groove 621 gradually increases along the extension direction from the bottom of the first oil groove 621 to the groove mouth of the first oil groove 621” can be understood as “the flow cross-section of the first oil groove 621 gradually increases along the extension direction from the side of the stopper 30 close to the hydraulic pump 50 to the side of the stopper 30 away from the hydraulic pump 50”.

[0077] Specifically, along the extension direction from the bottom of the second oil groove 622 to the notch of the second oil groove 622, the flow cross section of the second oil groove 622 gradually increases. In this way, it is easy for wear debris to smoothly enter the second oil groove 622 through the first oil groove 621, avoiding the situation where wear debris cannot smoothly enter due to the small flow cross section at the notch of the second oil groove 622. In addition, the setting of the above structure can also avoid the situation where the corresponding structure is too hollowed out due to the excessive groove volume of the second oil groove 622, resulting in insufficient structural strength. This gradual flow cross section design can effectively reduce the resistance of the lubricating oil during the circulation process and increase the circulation speed of the lubricating oil.

[0078] Specifically, “the flow cross-section of the second oil groove 622 gradually increases along the extension direction from the bottom of the second oil groove 622 to the groove mouth of the second oil groove 622” can be understood as “the flow cross-section of the second oil groove 622 gradually increases along the extension direction from the side of the stop member 30 close to the hydraulic pump 50 to the side of the stop member 30 away from the hydraulic pump 50”.

[0079] In this embodiment, the first oil groove 621 is a V-shaped groove. The above structure can ensure that the wear debris generated by the friction between the crankshaft structure 40 and the stopper 30 can smoothly enter the first oil groove 621, avoiding the situation where the wear debris cannot smoothly enter due to the small flow cross section at the groove of the first oil groove 621. In addition, the setting of the above structure can also avoid the situation where the corresponding structure is too hollowed out due to the large groove volume of the first oil groove 621, resulting in insufficient structural strength. Specifically, in this embodiment, the first oil groove 621 is set on the support surface 32.

[0080] In this embodiment, the second oil groove 622 is an annular groove, so that the wear debris collected by the plurality of first oil grooves 621 can be gathered in the second oil groove 622, and the lubricating oil at the first oil groove 621 can carry the wear debris and gather in the second oil groove 622, so that the wear debris can be brought out of the filter cavity 21 through the flow of lubricating oil. Specifically, the second oil groove 622 is provided on the support surface 32. Specifically, the annular groove can be a circular annular groove.

[0081] Specifically, the first oil-flowing groove 621 is a V-shaped inclined groove, and the side surfaces on both sides of the V-shaped inclined groove are inclined surfaces. Three V-shaped inclined grooves may be evenly distributed along the circumferential direction.

[0082] Specifically, the oil passage 63 includes a first oil hole 631 and a second oil hole 632. The first oil hole 631 extends axially along the avoidance through hole 11, and one end of the first oil hole 631 forms an oil inlet end. The second oil hole 632 extends radially along the avoidance through hole 11, and one end of the second oil hole 632 is connected to the other end of the first oil hole 631, and the other end of the second oil hole 632 forms an oil outlet end. Such a structural arrangement can optimize the flow path of the oil passage 63 and facilitate better removal of wear debris through the flow of lubricating oil. In addition, this design of the oil passage 63 combining axial and radial directions can effectively avoid dead corners of the lubricating oil during the circulation process and improve the smoothness of the flow of the lubricating oil.

[0083] Specifically, the aperture of the first oil hole 631 is d1, 1.5mm≤d1≤2mm. In this way, the wear debris can be smoothly brought into the first oil hole 631. When the aperture of the first oil hole 631 is too large, the hollowing out on the support seat 10 will be too large, affecting the support and connection stability of the support seat 10; when the aperture of the first oil hole 631 is too small, the wear debris will not be able to smoothly enter the first oil hole 631. In addition, the above structure can also ensure the flow speed of the lubricating oil to a certain extent, so that the wear debris can be smoothly taken away by the lubricating oil.

[0084] Specifically, the aperture of the second oil hole 632 is d2, 1.5mm≤d2≤2mm. In this way, the wear debris can be smoothly brought into the second oil hole 632. When the aperture of the second oil hole 632 is too large, the hollowing out on the support seat 10 will be too large, affecting the support and connection stability of the support seat 10; when the aperture of the second oil hole 632 is too small, the wear debris will not be able to smoothly enter the second oil hole 632. In addition, the above structure can also ensure the flow speed of the lubricating oil to a certain extent, so that the wear debris can be smoothly taken away by the lubricating oil.

[0085] In one embodiment, a relief portion 12 is provided on the support seat 10, and the relief portion 12 is located outside the filter cavity 21. The relief portion 12 is provided at the upper and lower ends of the portion of the support seat 10 located outside the filter cavity 21. With such a structural arrangement, it is possible to facilitate the lubricating oil to carry the wear debris through the relief portion 12 and avoid accumulation at the support seat 10. Specifically, the lubricating oil flowing through the relief portion 12 will carry the wear debris into the oil pool 81 located below the support seat 10, effectively utilizing the effect of gravity, thereby facilitating the lubricating oil to re-enter the oil pool 81, reducing the impact on the amount of lubricating oil in the oil pool 81, and realizing the recycling of the lubricating oil.

[0086] Specifically, the support seat 10 includes a main body 13 and at least two connecting protrusions 14, and the main body 13 is provided with an avoidance through hole 11 and an oil passage 63. At least two connecting protrusions 14 are arranged at intervals along the circumference of the main body 13 and are connected to the main body 13, and the gap between two adjacent connecting protrusions 14 of the at least two connecting protrusions 14 forms an avoidance portion 12. With such a structural arrangement, it is convenient to optimize the structure of the support seat 10, facilitate the smooth outflow of lubricating oil, and facilitate the effective connection and support effect through the connecting protrusions 14.

[0087] In another embodiment, the support assembly further includes an oil pipe 70, which is disposed outside the filter chamber 21, one end of which is connected to the oil outlet, and the other end of which is located below the one end of the oil pipe 70. With such a structural arrangement, the lubricating oil flowing out of the oil outlet can be smoothly introduced to the lower part through the oil pipe 70, and the wear debris mixed with the lubricating oil can be effectively guided by gravity. The above structure can effectively guide the lubricating oil and facilitate the collection of the lubricating oil.

[0088] Specifically, the oil pipe 70 is a bent pipe, and the above structure can effectively avoid other structures of the support assembly and facilitate the smooth guidance of the lubricating oil.

[0089] Specifically, the other end of the oil pipe 70 is located below the portion of the support seat 10 that is located outside the filter chamber 21, so that the lubricating oil flowing out through the oil pipe 70 can smoothly avoid the support seat 10, avoid the lubricating oil flowing out through the oil pipe 70 from accumulating at the support seat 10, and also facilitate the collection of the flowing lubricating oil.

[0090] Specifically, at least part of the filter element 20 is located in the oil pool 81, and the other end of the oil pipe 70 is connected to the oil pool 81. With such a configuration, the lubricating oil flowing out through the oil pipe 70 can smoothly enter the oil pool 81 located below the support seat 10, and the wear debris is effectively taken away by the lubricating oil under the gravity, so that the lubricating oil can be re-flowed into the oil pool 81, reducing the impact on the amount of lubricating oil in the oil pool 81, and realizing the recycling of the lubricating oil.

[0091] In this embodiment, the crankshaft structure 40 includes a crankshaft 41 and a connecting member 42, and the crankshaft 41 has a connecting hole 411. The connecting member 42 includes a first connecting portion 421, a second connecting portion 422, and a third connecting portion 423 connected in sequence, and the connecting member 42 has a connecting hole 424 that passes through the first connecting portion 421, the second connecting portion 422, and the third connecting portion 423, and the connecting hole 424 is connected to the connecting hole 411. Among them, the crankshaft 41, the first connecting portion 421, and the second connecting portion 422 form a part of the crankshaft structure 40, and the third connecting portion 423 forms another part of the crankshaft structure 40; the first connecting portion 421 is installed in the connecting hole 411 and connected to the crankshaft 41, the second connecting portion 422 is located between the end of the crankshaft 41 and the stopper 30, and a connecting channel 62 is provided between the second connecting portion 422 and the stopper 30. By adopting such a structural setting, the connection method between the crankshaft structure 40 and the hydraulic pump 50 is optimized, so as to ensure that the crankshaft structure 40 can stably drive the hydraulic pump 50 to operate.

[0092] Specifically, the first connecting portion 421 and the connecting hole 411 are interference fit.

[0093] Specifically, the stopper 30 in all the above embodiments may also be referred to as a lower stopper plate, that is, a lower stopper plate located below the crankshaft structure 40 .

[0094] Through the support assembly provided by the above embodiment, through the sequential connection of the oil inlet channel 61, the connecting channel 62 and the oil outlet channel 63, it is possible to achieve that the metal iron filings generated by the contact and rotation of the crankshaft structure 40 and the stopper 30 during the operation of the scroll compressor are carried by the lubricating oil and enter the oil pool 81 at the bottom of the compressor, thereby preventing the metal iron filings from entering the filter chamber 21 and the inside of the oil pump to block the pump oil flow path and affect the oil supply efficiency of the oil pump, thereby ensuring the long-term stable and efficient operation of the oil pump and the long-term reliability of the scroll compressor.

[0095] A second embodiment of the present invention provides a compressor, which includes: the support assembly provided above and a shell 80 , wherein the support seat 10 of the support assembly is fixedly installed in the shell 80 .

[0096] In this embodiment, the bottom of the shell 80 has an oil pool 81, and a portion of the crankshaft structure 40 and / or the stopper 30 are made of iron; the compressor also includes a magnetic adsorption component 160, which is installed in the oil pool 81 and is located outside the filter chamber 21 surrounded by the filter element 20 of the support assembly and the support seat 10 of the support assembly.

[0097] It should be noted that “a portion of the crankshaft structure 40 and / or the stopper 30 are made of iron” can be understood as a portion of the crankshaft structure 40 and / or the stopper 30 being made of pure iron or a material containing iron.

[0098] Specifically, the support assembly is the support assembly provided above.

[0099] Among them, the magnetic adsorption component 160 is arranged opposite to the avoidance portion 12 of the support assembly, so that the magnetic adsorption component 160 can effectively adsorb the iron-containing wear debris in the lubricating fluid flowing through the avoidance portion 12, thereby avoiding the wear debris from being dispersed in the oil pool 81, and better avoiding the wear debris from avoiding the filter holes of the filter element 20, thereby facilitating better avoiding the clogging of the filter holes of the filter element 20.

[0100] Specifically, the magnetic adsorption component 160 is arranged opposite to the other end of the oil pipe 70 of the support assembly, so that the magnetic adsorption component 160 can effectively adsorb the iron-containing wear debris in the lubricating fluid flowing through the other end of the oil pipe 70, thereby avoiding the wear debris from being dispersed in the oil pool 81, and better avoiding the wear debris from avoiding the filter holes of the filter element 20, thereby facilitating better avoiding the clogging of the filter holes of the filter element 20.

[0101] Specifically, the magnetic adsorption member 160 is fixed to the bottom of the housing 80 to improve the adsorption effect of the magnetic adsorption member 160 and effectively adsorb the wear debris deposited at the bottom of the oil pool 81. Specifically, the magnetic adsorption member 160 can be welded to the bottom of the housing 80.

[0102] Specifically, the magnetic adsorbent 160 is an annular structure, which is simple and easy to install and fix. Specifically, the magnetic pole direction of the magnetic adsorbent 160 is along the axial direction of the annular structure. At this time, the lubricating oil carrying wear debris can flow back more accurately and pass through the magnetic adsorbent 160, so that the magnetic adsorbent 160 can more easily adsorb metal impurities and achieve a better impurity removal effect.

[0103] Specifically, the magnetic adsorption component 160 is spaced apart from the filter component 20 of the support assembly so as to effectively adsorb the wear debris in the oil pool 81 near the filter component 20 .

[0104] Specifically, the magnetic adsorption member 160 may be a magnet, and the magnetic flux density of the magnetic adsorption member 160 is greater than 500 Gauss.

[0105] like Figure 1 As shown, the compressor in this embodiment is mainly a scroll compressor, which mainly includes a motor 100, an upper bracket 150, a lower bracket (also referred to as a support seat 10), a fixed scroll 130, a movable scroll 140, a cross slip ring 110, a crankshaft 41, etc. The stator of the motor 100 is fixed to the housing 80 by shrink sleeve, and the upper bracket 150 is fixed to the housing 80 by spot welding. The movable scroll 140 and the fixed scroll 130 are oppositely mounted on the upper bracket 150 with a phase angle difference of 180 degrees. The movable scroll 140 moves under the drive of the crankshaft 41 and meshes with the fixed scroll 130 to form a series of crescent-shaped closed cavities that are isolated from each other and have continuously changing volumes. The fixed scroll 130 is fixed to the upper bracket 150 by screw fasteners. The lower bracket is fixed to the lower support ring 90 by screws, and the lower support ring 90 is fixed to the housing 80 by spot welding. The housing 80 includes an upper cover 82 , a cylinder 83 , and a lower cover 84 which are connected in sequence.

[0106] When the compressor is running, the motor 100 drives the crankshaft 41 to rotate, and the crank of the crankshaft 41 drives the movable scroll 140 to move. Under the anti-rotation restriction of the cross slip ring 110, the movable scroll 140 performs translational motion around the center of the crankshaft 41 at a fixed radius. The refrigerant entering from the suction pipe 120 is sucked into the crescent-shaped suction cavity formed by the movable scroll 140 and the fixed scroll, and is discharged from the exhaust port of the fixed scroll after being compressed, and enters the cavity between the upper cover 82 and the fixed scroll, and then enters the cavity between the upper bracket 150 and the motor 100 through the exhaust groove of the fixed scroll and the upper bracket 150, and partially enters the lower end of the motor 100 through the through-flow groove between the motor 100 and the housing 80, and finally the high-pressure exhaust refrigerant is discharged through the exhaust pipe.

[0107] like Figure 1 The figure shows the schematic diagram of the scroll compressor of the present invention. Figure 2 , Figure 3 and Figure 4 The figure shows the structural diagram of the support assembly. Figure 2 and Figure 3 The arrows in the figure show the direction of the oil flow of the lubricating oil during the operation of the compressor. Figure 5 The exploded diagram of the support assembly is shown in FIG. 1 . The oil pump and the filter 20 are fixed to the lower bracket by screws. The lower thrust plate (also called the stopper 30 ) is placed concentrically with the oil pump and the lower bracket and wrapped between the lower bracket and the oil pump. The lower bracket is fixed under the lower support ring 90 by screws. Figure 6 , Figure 7 It is a structural schematic diagram of the lower thrust plate and lower bracket parts. There is an oil hole 31 in the center of the lower thrust plate to allow the connecting piece 42 to be inserted. Three V-shaped bevel grooves (corresponding to the first oil groove 621) are evenly arranged in the circumferential direction, and a circular annular groove (corresponding to the second oil groove 622) is opened at the tail of the V-shaped bevel groove and connected with it. The outer diameter of the circular annular groove should avoid interference with the screw hole 33 on the lower thrust plate. The inner diameter of the circular annular groove should be larger than the outer diameter of the oil hole 31. An axial flow hole (corresponding to the first oil hole 631) and a radial flow hole (corresponding to the second oil hole 632) are opened in the lower bracket to ensure that the circular annular groove is directly opposite to the axial flow hole of the lower bracket. A radial flow hole is opened at the tail of the axial flow hole. The diameters of the axial flow hole and the radial flow hole should be between φ1.5mm. and φ2mm to ensure that metal impurities can pass smoothly without generating excessive oil discharge resistance. The radial flow hole is connected with the compression chamber.

[0108] When the scroll compressor starts to operate, the drive drives the oil pump to run at high speed, the meshing rotation of the gears inside the oil pump generates negative pressure and sucks part of the lubricating oil in the bottom oil pool 81 of the compressor lower cover 84 into the oil through hole 31 at the center of the lower thrust plate, and brings the metal impurities generated by the wear of the drive and the lower thrust plate to the circular annular groove along the V-shaped inclined groove. At this time, the lubricating oil carrying the metal impurities flows around the circular annular groove and then flows along the axial flow holes and radial flow holes at the lower bracket to discharge the metal impurities to the bottom oil pool 81 of the lower cover 84, and finally the metal impurities are adsorbed on the magnet at the lower cover 84. This impurity removal flow path (corresponding to the oil inlet channel 61, the connecting channel 62 and the oil outlet channel 63 connected in sequence) can effectively bring the metal impurities generated by the wear of the contact surface and the support surface 32 when the compressor is running to the oil pool 81 at the bottom of the compressor and be adsorbed by the magnet at the lower cover 84, thereby avoiding the metal iron filings generated by driving wear during the operation of the scroll compressor to be discharged and deposited at the bottom of the oil pump filter. During the operation of the compressor, this part of the iron filings are brought into the interior by the lubricating oil to block the oil flow path, thereby affecting the oil pump's oil supply efficiency to the pump body, thereby improving the long-term operation reliability of the scroll compressor.

[0109] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by providing the oil inlet channel 61, the connecting channel 62 and the oil outlet channel 63, the metal iron chips generated by the wear between at least part of the crankshaft structure 40 and the stopper 30 during the operation of the compressor can be discharged to the bottom of the lower cover 84 of the housing 80 along the oil inlet channel 61, the connecting channel 62 and the oil outlet channel 63 with lubricating oil as the medium and adsorbed to the magnet fixed at the lower cover 84, thereby preventing the metal iron chips from remaining in the filter chamber 21 of the filter element 20 and affecting the normal operation of the hydraulic pump 50, thereby preventing the iron chips impurities from being deposited in the filter chamber 21 of the filter element 20 and then being sucked into the hydraulic pump 50, reducing the probability of the hydraulic pump 50 being blocked or stuck, and ensuring the long-term stable operation of the hydraulic pump 50, the pumping efficiency and the long-term reliability of the scroll compressor. Ensure that the hydraulic pump 50 supplies oil to the pump body assembly of the compressor in a long-term stable and efficient manner, and improve the reliability of the operation of the existing scroll compressor. The above embodiment solves the problem that metal filings remain in the filter chamber 21 and cannot be removed, and solves the problem that metal filings enter the oil pump and block the oil flow path, thereby affecting the oil supply efficiency of the oil pump.
