Description

Technical Field

[0001] This application relates to the field of compressor technology, specifically to a vane assembly for a compressor and a compressor. Background Technology

[0002] Currently, in roller compressors, the cylinder end face typically mates with a flange to form a sealed compression chamber. The crankshaft drives the rollers to roll within the compression chamber. A vane is slidably positioned within a groove communicating with the compression chamber. Through dynamic contact between the vane head and the outer wall of the roller, the compression chamber is divided into an intake chamber and an exhaust chamber. During operation, friction occurs between the vane and the flange, causing wear and increasing the gap between the vane and the flange, thus affecting the sealing between the intake and exhaust chambers.

[0003] The related technology discloses a sealing device for a rolling rotor compressor. The rolling rotor compressor includes a cylinder end cover, a vane, and a sealed cavity. The vane divides the sealed cavity into a low-pressure cavity and a high-pressure cavity. The vane has a first end face facing the cylinder end cover. The sealing device includes a groove and a sealing element. The groove is formed on the first end face, and the sealing element is installed in the groove. The sealing element has opposing first and second sides and a sealing surface facing the cylinder end cover. The first side is close to the high-pressure cavity, and the second side is close to the low-pressure cavity. The angle between the sealing surface and the first side is less than 90°. The sealing surface is not lower than the first end face. The sealing element floats relative to the groove in the direction of approaching and moving away from the cylinder end cover, which can reduce the size of the gap between the vane and the cylinder end cover without changing the distance between the vane and the cylinder end cover.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] In related technologies, the seal floats out of the groove under the pressure difference between the refrigerant in the high-pressure chamber and the refrigerant in the low-pressure chamber. During compressor operation, the fluctuation of the pressure difference will cause the floating instability of the seal, thus affecting the sealing effect.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0044] Combination Figure 1-3 As shown, this disclosure provides a vane assembly 103 for a compressor 10, including a vane 30 and a seal 33.

[0045] The slide 30 is provided with a first channel 31 that communicates with an external gas source. The end face of the slide 30 is provided with a groove 32 that communicates with the first channel 31 so that the airflow from the external gas source can flow into the groove 32 through the first channel 31. The seal 33 is movably disposed in the groove 32 and is configured to float relative to the groove 32 under the drive of the airflow.

[0046] The external gas source comes from the gas supply device outside the compressor, which is independent of the refrigerant system inside the compressor. The external gas source is connected to the compressor cylinder through a dedicated pipeline.

[0047] Using the vane assembly 103 for compressor 10 provided in this embodiment, airflow from an external gas source can flow into groove 32 through first channel 31 and act on seal 33. The pressure of the airflow provides a stable force to seal 33, thereby driving seal 33 to float relative to groove 32. This stable airflow driving method can effectively improve the floating stability of seal 33. The floating of seal 33 can compensate for the wear gap of vane 30 and improve the contact tightness between seal 33 and mating parts.

[0048] Optionally, the gas source from the outside can be the same refrigerant gas used inside the compressor.

[0049] The external gas source uses the same refrigerant gas as the compressor's internal gas. This avoids pressure fluctuations caused by mixing different gases when the external gas source flows into the compressor, resulting in a smoother compressor operation. Simultaneously, this maintains the stability of the refrigerant gas composition inside the compressor, preventing imbalances caused by the intrusion of external gases, and ensuring stable operation of the refrigeration cycle and consistent cooling performance.

[0050] Optionally, combined Figure 2 As shown, the height of the seal 33 is less than or equal to the height of the groove 32.

[0051] This prevents the seal 33 from protruding too high from the groove 32, thereby avoiding interference between the seal 33 and the flange 50 and causing wear.

[0052] Optionally, combined Figure 2 and Figure 3 As shown, the length and width dimensions of the seal 33 are adapted to the length and width dimensions of the groove 32 so that the seal 33 can simultaneously achieve floating and sealing.

[0053] This allows the seal 33 to exist stably and float freely within the groove 32, preventing it from becoming stuck due to being too large or failing to seal properly due to being too small. The groove 32 and the seal 33 are shaped to match, and their cross-sections at the end faces can be rectangular, providing uniform sealing pressure. Alternatively, the cross-sections of the groove 32 and the seal 33 at the end faces can also be other shapes.

[0054] Optionally, combined Figure 1-5As shown, the end face of the slide 30 includes a first axial end face 301; there are multiple grooves 32, including a first groove 321, which is located on the first axial end face 301 and is connected to the first channel 31; there are multiple sealing elements 33, including a first sealing element 331, which is located in the first groove 321.

[0055] By providing a first groove 321 on the first axial end face 301 of the slide 30 and providing a first seal 331 in the first groove 321, the wear gap of the slide 30 on the first axial end face 301 can be effectively reduced, thereby improving the sealing performance between the first axial end face 301 and the corresponding mating parts.

[0056] In the compressor 10 structure, the flange 50 is located on the axial end side of the cylinder 20. The axial end face of the vane 30 is usually in contact with the flange 50, and friction easily occurs between the axial end face of the vane 30 and the flange 50 during the movement of the vane 30. When the airflow from the external gas source enters the first channel 31 of the vane 30, it drives the first seal 331 to float stably from the first axial end face 301 of the vane 30 along the axial direction of the cylinder 20 toward the corresponding flange 50, which can reduce the wear gap between the first axial end face 301 of the vane 30 and the flange 50. This can enhance the sealing effect between the first axial end face 301 of the vane 30 and the corresponding flange 50.

[0057] Optionally, combined Figure 1-3 As shown, the first channel 31 includes a diversion channel 311 and a first pressure channel 312. The diversion channel 311 is connected to an external gas source and extends along the length of the slide plate 30. One end of the first pressure channel 312 is connected to the diversion channel 311, and the other end of the first pressure channel 312 is connected to the first groove 321.

[0058] Combination Figure 5 As shown, the x-axis indicates the length direction of the slider, and the y-axis indicates the height direction of the slider.

[0059] The diversion channel 311 extends along the length of the slide vane 30, enabling it to evenly guide the airflow from the external gas source into the interior of the slide vane 30, effectively maintaining stable airflow pressure. Combined with... Figure 3 and Figure 4As shown, the first groove 321 is located on the first axial end face 301 of the slide 30. The first pressure channel 312 connects the diversion channel 311 and the first groove 321, which can accurately guide the airflow to the first groove 321, so that the airflow directly acts on the first seal 331, thereby providing sufficient pressure to the first seal 331 to achieve a floating seal. In addition, through the staged diversion channel 311 and the first pressure channel 312, the impact force of the airflow can be reduced, thereby maintaining the floating state of the first seal 331 more stably.

[0060] Optionally, combined Figure 1-3 As shown, the end face of the slide 30 also includes a second axial end face 302, and the first axial end face 301 and the second axial end face 302 are opposite to each other along the height direction of the slide 30; the plurality of grooves 32 also include a second groove 322, the second groove 322 is disposed on the second axial end face 302, and the second groove 322 is connected to the first channel 31; the plurality of seals 33 also include a second seal 332, the second seal 332 is disposed in the second groove 322.

[0061] By providing a second groove 322 on the second axial end face 302 of the slide 30 and providing a second seal 332 in the second groove 322, the wear gap of the slide 30 on the second axial end face 302 can be effectively reduced, thereby improving the sealing performance between the second axial end face 302 and the corresponding mating parts.

[0062] In the compressor 10, flanges 50 are typically provided on both axial ends of the cylinder 20. The height direction of the vane 30 is consistent with the axial direction of the cylinder 20, and the first axial end face 301 and the second axial end face 302 of the vane 30 correspond to a flange 50 respectively. When the airflow from the external gas source enters the first channel 31 of the vane 30, it drives the second seal 332 to float stably from the second axial end face 302 of the vane 30 along the axial direction of the cylinder 20 toward the corresponding flange 50, which can reduce the wear gap between the second axial end face 302 of the vane 30 and the flange 50. This can enhance the sealing effect between the second axial end face 302 of the vane 30 and the corresponding flange 50. By providing a first groove 321 and a second groove 322 on the first axial end face 301 and the second axial end face 302 along the height direction of the slide plate 30, and installing a first seal 331 and a second seal 332 respectively, when the airflow from an external gas source enters the first channel 31 of the slide plate 30, it will simultaneously drive the first seal 331 and the second seal 332 to float along the height direction of the slide plate 30. This can effectively improve the sealing performance between the slide plate 30 and the corresponding flange 50.

[0063] Optionally, combined Figure 1-3As shown, the first channel 31 also includes a second pressure channel 313. One end of the second pressure channel 313 is connected to the diversion channel 311, and the other end of the second pressure channel 313 is connected to the second groove 322.

[0064] The first axial end face 301 and the second axial end face 302 are opposite each other along the height direction of the slide 30. A first groove 321 is located on the first axial end face 301, and a second groove 322 is located on the second axial end face 302. The diversion channel 311 extends along the length direction of the slide 30, serving as the main channel. A first pressure-guiding channel 312 connects the diversion channel 311 and the first groove 321, and a second pressure-guiding channel 313 connects the diversion channel 311 and the second groove 322. The first pressure-guiding channel 312 and the second pressure-guiding channel 313 are located on opposite sides of the diversion channel 311 along the height direction of the slide 30. The airflow direction within the first channel is as follows: Figure 3 As indicated by the middle arrow, the airflow from the external gas source enters the diversion channel 311 and then flows through the first pressure-receiving channel 312 and the second pressure-receiving channel 313 into the first groove 321 and the second groove 322, respectively. This provides uniform and stable airflow power to both the first seal 331 and the second seal 332, allowing them to float stably. This staged flow path design increases the length and complexity of the airflow path, effectively improving the uniformity and stability of the airflow while reducing its impact force.

[0065] Optionally, combined Figure 1-3 As shown, the first pressure channel 312 and the second pressure channel 313 are symmetrically arranged relative to the diversion channel 311 along the height direction of the slider 30.

[0066] The first pressure-applying channel 312 and the second pressure-applying channel 313 are symmetrically arranged relative to the diversion channel 311, resulting in a more uniform flow distribution when the airflow enters the first pressure-applying channel 312 and the second pressure-applying channel 313 from the diversion channel 311. This uniform airflow distribution allows the first sealing element 331 and the second sealing element 332 to float synchronously and stably, thereby improving the consistency of the seal. Furthermore, the symmetrical arrangement of the first pressure-applying channel 312 and the second pressure-applying channel 313 also ensures a more balanced force on both ends of the sliding plate 30 along the height direction when subjected to airflow. This reduces the possibility of bending or twisting deformation of the sliding plate 30 due to uneven force, effectively enhancing the stability and sealing performance of the sliding plate 30.

[0067] Optionally, combined Figure 1-3 As shown, there are multiple first pressure channels 312, and the multiple first pressure channels 312 are arranged along the length direction of the slider 30.

[0068] The flow distribution channel 311 extends along the length of the vane 30, and multiple first pressure-sensing channels 312 are arranged along the length of the vane 30, allowing airflow to enter the first groove 321 through multiple points. This more evenly distributes the airflow across the entire length of the first groove 321, avoiding uneven airflow distribution within the first groove 321 caused by a single first pressure-sensing channel 312. During compressor 10 operation, the contact surface between the vane 30 and the flange 50 is an area along the length of the vane 30. The multiple first pressure-sensing channels 312 ensure that the first seal 331 receives sufficient airflow at various positions along the length of the vane 30 to maintain a good floating state, thereby enhancing the sealing effect between the seal and the flange. Furthermore, the synergistic effect of the multiple first pressure-sensing channels 312 improves the driving effect on the first seal 331, preventing floating failure caused by blockage of a single first pressure-sensing channel 312, and enabling the first seal 331 to float continuously and stably.

[0069] Optionally, combined Figure 1-3 As shown, there are multiple second pressure channels 313, which are arranged along the length of the slider 30.

[0070] Similarly, the flow distribution channel 311 extends along the length of the vane 30, and multiple second pressure-sensing channels 313 are arranged along the length of the vane 30, allowing airflow to enter the second groove 322 through multiple points. This allows for more even distribution of airflow across the entire length of the second groove 322, avoiding uneven airflow distribution within the second groove 322 caused by a single second pressure-sensing channel 313. During compressor 10 operation, the contact surface between the vane 30 and the flange 50 is an area along the length of the vane 30. Multiple second pressure-sensing channels 313 ensure that the second seal 332 receives sufficient airflow at various positions along the length of the vane 30 to maintain a good floating state, thereby enhancing the sealing effect between the seal and the flange. Furthermore, the synergistic effect of multiple second pressure-sensing channels 313 improves the driving effect on the second seal 332, preventing floating failure caused by blockage of a single second pressure-sensing channel 313, and enabling the second seal 332 to float continuously and stably.

[0071] Optionally, combined Figure 1-3 As shown, multiple first pressure channels 312 are evenly distributed along the length of the slide plate 30.

[0072] Multiple first pressure channels 312 are evenly distributed along the length of the slide plate 30, which allows airflow to enter each part of the first groove 321 more evenly, so that the first seal 331 can receive the same intensity of airflow force at every position along the length of the slide plate 30. This improves the force balance of the first seal 331 and prevents the first seal 331 from tilting or floating.

[0073] Optionally, combined Figure 1-3 As shown, multiple second pressure channels 313 are evenly distributed along the length of the slider 30.

[0074] Multiple second pressure channels 313 are evenly distributed along the length of the slide plate 30, which allows airflow to enter each part of the second groove 322 more evenly, so that the second seal 332 can receive the same intensity of airflow force at every position along the length of the slide plate 30. This improves the force balance of the second seal 332 and prevents the second seal 332 from tilting or floating.

[0075] Combination Figure 8 As shown, this embodiment of the present disclosure provides a compressor 10, including a cylinder 20 and a vane assembly 103 for the compressor 10 as described in any of the above-disclosed embodiments. The cylinder 20 is provided with a vane groove 22 and a second channel 21; a vane 30 is disposed in the vane groove 22, one end of the second channel 21 is connected to an external gas source, and the other end of the second channel 21 is connected to a first channel 31.

[0076] The compressor 10 provided in this embodiment of the present disclosure, because it includes the vane assembly 103 for the compressor 10 as described in any of the above-disclosed embodiments, has all the beneficial effects of the vane assembly 103 for the compressor 10 as described in any of the above-disclosed embodiments. The vane 30 is disposed in the vane groove 22 and can reciprocate along the vane groove 22. The cylinder 20 is provided with a second channel 21 connecting an external gas source and the first channel 31 of the vane 30. The airflow from the external gas source flows through the first channel 31 and then into the first channel 31 of the vane 30, and then into the groove 32 to drive the seal 33 to float stably. The floating of the seal 33 can compensate for the wear gap of the vane 30 and improve the contact tightness between the seal 33 and the mating parts.

[0077] Optionally, combined Figure 5-7 As shown, the slider 30 includes a slider tail 34, which is close to the rear groove wall 223 of the slider groove 22. The inlet of the second channel 21 is connected to an external gas source, and the outlet of the second channel 21 is located between the slider tail 34 and the rear groove wall 223 of the slider groove 22. The inlet of the first channel 31 is located at the slider tail 34, and the first channel 31 and the second channel 21 are connected through the slider groove 22.

[0078] This allows the airflow from the external gas source to flow directly from the tail 34 of the slide plate into the first channel 31 after entering the slide plate groove 22 through the second channel 21, providing a uniform and stable force for the stable floating of the seal 33. When the first channel 31 includes a diversion channel 311, a first pressure-receiving channel 312, and a second pressure-receiving channel 313, the inlet of the diversion channel 311 is located at the tail 34 of the slide plate. This provides airflow to the first groove 321 and the second groove 322 along the entire length of the slide plate 30, ensuring that the first seal 331 and the second seal 332 receive a uniform and stable force throughout the entire length of the slide plate 30, thereby improving the floating stability of the first seal 331 and the second seal 332. Furthermore, the airflow can also directly act on the tail 34 of the slide plate, propelling the slide plate 30 along the slide plate groove 22.

[0079] Optionally, combined Figure 6 As shown, the second channel 21 includes a first axial channel 211 and a tangential channel 212. The first axial channel 211 extends along the axial direction of the cylinder 20, and one end of the first axial channel 211 is opened on the end face of the cylinder 20. The tangential channel 212 extends along the tangential direction of the cylinder 20. One end of the tangential channel 212 is connected to the other end of the first axial channel 211, and the other end of the tangential channel 212 is connected to the second end of the sliding groove.

[0080] The tangential direction of cylinder 20 refers to the circumferential tangential direction perpendicular to the axial direction of cylinder 20. The second channel 21 includes a first axial channel 211 extending along the axial direction of cylinder 20 and a tangential channel 212 extending along the tangential direction of cylinder 20. This allows the airflow direction to switch from axial to tangential before flowing into the vane groove 22, changing the path of the airflow into the vane groove 22 and providing a buffering and adjustment process before entering the vane groove 22, thereby improving the uniformity of the airflow. Simultaneously, this also extends the airflow path, providing more buffering for the airflow and effectively reducing the impact force of the airflow on the vane groove 22 and the vane 30. The gas flow direction within the second channel 21 is as follows: Figure 6 The direction indicated by the middle arrow.

[0081] Optionally, combined Figure 8 As shown, the compressor 10 also includes a flange 50, which is located on the axial end face 24 of the cylinder. The flange 50 is provided with a third channel 51, one end of which is an inlet for an external gas source, and the other end of which is connected to the second channel 21.

[0082] A third channel 51 is provided on flange 50, connecting the external gas source and the first channel 31, so that the airflow can be stably and continuously delivered from the external gas source to the sliding vane groove 22, providing a reliable power source for the sliding vane 30 and the seal 33. Placing the external gas source inlet on flange 50 facilitates connection to an external gas supply system and simplifies the flow path layout. By providing the third channel 51 on flange 50, the structural strength of cylinder 20 is improved, and sealing treatment at the connection between flange 50 and cylinder 20 is facilitated, improving the overall sealing performance of the flow path system.

[0083] Optionally, combined Figure 8 As shown, the third channel 51 includes a radial channel 511 and a second axial channel 512. One end of the radial channel 511 is an external gas source inlet, which is located on the side wall of the flange 50, and the radial channel 511 extends radially along the flange 50. The second axial channel 512 extends axially along the flange 50. One end of the second axial channel 512 is connected to the radial channel 511, and the other end of the second axial channel 512 is connected to the first axial channel 211.

[0084] Flange 50 is located on the axial end of cylinder 20, and the radial direction of flange 50 is consistent with the radial direction of cylinder 20. An external gas source inlet is located on the side wall of flange 50, making full use of the side wall space to allow airflow to enter the interior of flange 50 radially. This reduces the impact on the structural strength of flange 50. After entering through the inlet on the side wall of flange 50, the airflow first flows radially within radial channel 511, then changes direction to flow axially within second axial channel 512. By switching the airflow direction, the airflow undergoes a change of direction within flange 50, thereby reducing the impact force of the airflow within flange 50. In the case where second channel 21 includes a first axial channel 211 and a tangential channel 212, the first axial channel 211 communicates with the second axial channel 512. The extension direction of second axial channel 512 matches that of first axial channel 211, allowing airflow to smoothly flow from third channel 51 into second channel 21. This reduces energy loss during the transition of airflow between flange 50 and cylinder 20, improving airflow delivery efficiency.

[0085] Optionally, combined Figure 6 and Figure 7 As shown, the inlet of the second channel 21 is located on the axial end face 24 of the cylinder.

[0086] Flange 50 is located on the axial end face 24 of the cylinder, and the inlet of the second channel 21 is opened on the axial end face 24 of the cylinder, which allows the second channel 21 to be more directly connected to the third channel 51 of flange 50. This optimizes the airflow path and improves the smoothness of airflow delivery.

[0087] Optionally, combined Figure 7 As shown, the axial end face 24 of the cylinder is provided with a first sealing groove 241. The first sealing groove 241 is arranged around the entrance of the second channel 21. A first sealing ring 25 is provided in the first sealing groove 241 to seal the connection between the third channel 51 and the second channel 21.

[0088] The first sealing groove 241 is arranged around the inlet of the second channel 21, and the first sealing ring 25 is installed inside the first sealing groove 241. This effectively forms a seal around the connection between the third channel 51 and the second channel 21, preventing gas from leaking out from the connection between the third channel 51 and the second channel 21. This improves the sealing of the gas flow path, thereby improving the airflow transmission efficiency.

[0089] Optionally, the axial end face of the flange 50 is provided with a second sealing groove, which is arranged around the outlet of the third channel 51. A second sealing ring is provided in the second sealing groove to seal the connection between the third channel 51 and the second channel 21.

[0090] The second sealing groove is arranged around the outlet of the third channel 51, and the second sealing ring is installed in the second sealing groove. It can effectively form a seal around the connection between the third channel 51 and the second channel 21, preventing gas from flowing out from the connection between the third channel 51 and the second channel 21. This can improve the sealing of the gas flow path in the pump body assembly, thereby improving the airflow transmission efficiency.
