Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a compressor and refrigeration equipment. Background Technology

[0002] Fixed-frequency screw compressors, commonly used in air conditioners, primarily achieve compression through the meshing of male and female rotors. A rotor casing surrounds these rotors to ensure that compressed gas can be drawn in from one end and discharged from the other. Generally, to allow fixed-frequency screw compressors to operate at different loads, leakage grooves are typically provided on the rotor casing, and movable sliders are installed on the outer wall of the rotor casing. The movement of these sliders controls the exposed area of ​​the leakage grooves, thereby adjusting the leakage rate and thus regulating the actual effective compression.

[0003] However, during daily use, the slider on the outer wall of the rotor cylinder is prone to jamming, which makes it impossible to adjust the compressor load. Utility Model Content

The elastic element is configured to be in a non-deformable state when the piston is close to the bottom of the piston chamber, and to gradually compress when the elastic element is away from the bottom of the piston chamber, so as to drive the piston toward the bottom of the piston chamber when the oil pressure in the piston chamber decreases, thereby moving the slide valve away from the auxiliary cylinder wall.

[0017] In some embodiments of this utility model, the piston chamber has multiple oil drain ports, which are spaced apart along the length of the piston chamber.

[0036] like Figures 1-5 As shown, this utility model provides a compressor 10, which includes a cylinder 100, a rotor cylinder 200, a slide valve 300, and an auxiliary cylinder wall 400. The rotor cylinder 200 is disposed inside the cylinder 100, and a rotor assembly 110 is disposed inside the rotor cylinder 200. A pressure relief groove 210 is provided on the rotor cylinder 200 to connect the inner wall and the outer wall of the rotor cylinder 200. The pressure relief groove 210 extends from one end of the rotor cylinder 200 to the other end along the length direction of the rotor assembly 110.

[0037] The pressure relief groove 210 connects the inner wall and the outer wall of the rotor cylinder 200, allowing the refrigerant in the rotor cylinder 200 to flow to the outside of the rotor cylinder 200 through the pressure relief groove 210, thereby reducing the load on the compressor 10.

[0038] Generally, the pressure relief groove 210 extends from one end of the rotor cylinder 200 to the other end along the length direction of the rotor assembly 110. Either the length of the pressure relief groove 210 is the same as the height of the rotor cylinder 200, that is, both ends of the pressure relief groove 210 penetrate the rotor cylinder 200; or the length of the pressure relief groove 210 is less than that of the rotor cylinder 200, that is, the pressure relief groove 210 extends from the top end of the rotor cylinder 200 to the bottom end of the rotor cylinder 200, and maintains a certain distance from the bottom end of the rotor cylinder 200.

[0039] It should be noted that the pressure relief groove 210 needs to maintain at least one end in communication with the end of the rotor cylinder 200 to ensure that the auxiliary cylinder wall 400 can be inserted into the pressure relief groove 210 from this end and partially exposed from the end of the pressure relief groove 210, so that after the pressure relief groove 210 is partially exposed by the slide valve 300, the auxiliary cylinder wall 400 has sufficient length to block the pressure relief groove 210 exposed by the slide valve 300.

[0040] The slide valve 300 is connected to the outer wall of the rotor cylinder 200 and covers the pressure relief groove 210 from the bottom end to the top end of the pressure relief groove 210. The slide valve 300 is configured to move along the length of the pressure relief groove 210 to adjust the length of the slide valve 300 covering the pressure relief groove 210.

[0041] The slide valve 300 is installed on the outer wall of the rotor cylinder 200 and is located near the bottom of the rotor cylinder 200. It covers part of the pressure relief groove 210 from the bottom to the top of the pressure relief groove 210 to ensure that the slide valve 300 can cooperate with the auxiliary cylinder wall 400 to completely seal the pressure relief groove 210.

[0042] It should be noted that the slide valve 300 is generally configured to move between a first position and a second position. The second position is located at the end of the first position away from the auxiliary cylinder wall 400. When the slide valve 300 is in the first position, it partially covers the pressure relief groove 210 from the bottom to the top, and abuts against the auxiliary cylinder wall 400 to completely seal the pressure relief groove 210. At this time, the compressor 10 is under rated load. When the slide valve 300 moves to the second position, the pressure relief groove 210 is gradually exposed. The refrigerant inside the rotor drum 200 can flow out from the exposed pressure relief groove 210, thereby reducing the load on the compressor 10. That is, the load on the compressor 10 can be gradually reduced by controlling the slide valve 300 to move towards the second position. It is understood that by setting the second position, the lower limit of the load on the compressor 10 can be determined. For example, when the slide valve 300 is in the second position, the slide valve 300 is completely disengaged from the pressure relief groove 210, and the pressure relief groove 210 covered by the slide valve 300 is fully exposed. At this time, the load on the compressor 10 is 25% of the rated load.

[0043] The auxiliary cylinder wall 400 is disposed in the pressure relief groove 210, abutting from one end of the rotor cylinder 200 to the end of the slide valve 300 near the auxiliary cylinder wall 400 and sealing the pressure relief groove 210. The auxiliary cylinder wall 400 is configured to move along the length of the pressure relief groove 210 to adjust the length of sealing the pressure relief groove 210.

[0044] The auxiliary cylinder wall 400 is movably disposed in the pressure relief groove 210. Under normal conditions, it remains in contact with the slide valve 300 in the first position. When the slide valve 300 is stuck, the exposed length of the pressure relief groove 210 can be adjusted by adjusting the position of the auxiliary cylinder wall 400. For example, when the slide valve 300 is stuck in the first position, it is necessary to reduce the load of the compressor 10. At this time, the auxiliary cylinder wall 400 can be controlled to move away from the slide valve 300, so that the originally completely blocked pressure relief groove 210 is exposed, thereby reducing the load of the compressor 10. Or, when the slide valve 300 is stuck between the second position and the first position, it is necessary to increase the load of the compressor 10. If the load of the compressor 10 needs to be the rated load, the auxiliary cylinder wall 400 can be moved toward the slide valve 300 and contact the slide valve 300 to completely block the pressure relief groove 210.

[0045] Based on the above description, it can be understood that the compressor 10 has a pressure relief groove 210 extending from one end to the other on the rotor cylinder 200, and a movable auxiliary cylinder wall 400 is provided in the pressure relief groove 210 to block the pressure relief groove 210. When the slide valve 300 is stuck, the position of the auxiliary cylinder wall 400 can be adjusted so that the auxiliary cylinder wall 400 blocks part of the pressure relief groove 210 or cooperates with the slide valve 300 to block all of the pressure relief groove 210, so as to ensure that the compressor 10 still has the function of adjustment when the slide valve 300 is stuck, thus avoiding unit failure.

[0046] In some embodiments, the rotor cylinder 200 has a plurality of pressure relief grooves 210, each including at least a first pressure relief groove and a second pressure relief groove, which are spaced apart along the circumferential direction of the rotor cylinder 200. The compressor 10 has a plurality of slide valves 300, each including at least a first slide valve and a second slide valve. The first slide valve is connected to the rotor cylinder 200 and covers the first pressure relief groove, while the second slide valve is connected to the rotor cylinder 200 and covers the second pressure relief groove. The compressor 10 has a plurality of auxiliary cylinder walls 400, each including at least a first auxiliary cylinder wall 400 and a second auxiliary cylinder wall 400. The first auxiliary cylinder wall 400 is disposed in the first pressure relief groove, and the second auxiliary cylinder wall 400 is disposed in the second pressure relief groove.

[0047] It is understood that in this embodiment, the compressor 10 has multiple pressure relief grooves 210, and each pressure relief groove 210 is provided with a corresponding slide valve 300 and auxiliary cylinder wall 400. When the slide valve 300 and auxiliary cylinder wall 400 of one set of pressure relief grooves 210 are stuck, the slide valve 300 and auxiliary cylinder wall 400 of the other set can be controlled to work, so as to ensure that the compressor 10 works normally.

[0048] Generally, when the rotor cylinder 200 has a first pressure relief groove, a second pressure relief groove, and corresponding first slide valve, second slide valve, first auxiliary cylinder wall 400, and second auxiliary cylinder wall 400, when the first slide valve is stuck, the first auxiliary cylinder wall 400 is preferentially controlled to move to the first slide valve and abut against the first slide valve to ensure that the first pressure relief groove is completely closed. At the same time, the second slide valve is controlled to perform load reduction or load increase actions. After the second slide valve is stuck, the second auxiliary cylinder wall 400 performs load reduction or load increase actions.

[0049] In some embodiments, the length of the auxiliary cylinder wall 400 is greater than or equal to the length of the pressure relief groove 210.

[0050] It is understandable that the length of the auxiliary cylinder wall 400 is greater than or equal to the length of the pressure relief groove 210, ensuring that the pressure relief groove 210 can be completely sealed by the auxiliary cylinder wall 400 alone. For example, when the slide valve 300 is stuck in the second position and the slide valve 300 is completely disengaged from the pressure relief groove 210, if you want to completely seal the pressure relief groove 210, you can control the auxiliary cylinder wall 400 to move to the bottom of the pressure relief groove 210 to completely seal the pressure relief groove 210.

[0051] Meanwhile, at least one end of the pressure relief groove 210 is connected to the end of the rotor cylinder 200, that is, it can ensure that when the slide valve 300 is in the first position, the part of the auxiliary cylinder wall 400 that is not in contact with the pressure relief groove 210 can be inserted into the pressure relief groove 210 when the slide valve 300 is in the second position, so as to completely seal the pressure relief groove 210.

[0052] In some embodiments, the compressor 10 further includes a first drive mechanism 500 and an oil delivery system. The first drive mechanism 500 includes a base 510, a piston 520, an elastic element 530, and a connecting rod 540. The base 510 is provided with a closed piston chamber 511. The piston 520 is movably disposed in the piston chamber 511. One end of the connecting rod 540 is connected to the piston 520, and the other end of the connecting rod 540 passes through the top of the piston chamber 511 and is connected to the slide valve 300. The bottom of the piston chamber 511 is provided with a first oil delivery port 512, which is connected to the oil delivery system, so as to increase the oil pressure in the piston chamber 511 under the oil supply of the oil delivery system, drive the piston 520 to move toward the top of the piston chamber 511, and cause the slide valve 300 to move toward the auxiliary cylinder wall 400.

[0053] When the piston 520 and the bottom of the piston chamber 511 are filled with oil, the pressure will push the piston 520 toward the top of the piston chamber 511, and then drive the slide valve 300 toward the auxiliary cylinder wall 400 through the piston 520.

[0054] One end of the elastic element 530 is connected to the piston 520, and the other end of the elastic element 530 is connected to the top of the piston chamber 511. The elastic element 530 is configured to be in a non-deformable state when the piston 520 is close to the bottom of the piston chamber 511, and to gradually compress when the elastic element 530 is away from the bottom of the piston chamber 511, so that when the oil pressure in the piston chamber 511 decreases, the piston 520 is driven to move toward the bottom of the piston chamber 511, so that the slide valve 300 is away from the auxiliary cylinder wall 400.

[0055] The elastic element 530 is configured to be in a non-deformable state when the piston 520 is close to the bottom of the piston chamber 511, that is, the slide valve 300 is in the second position in the above embodiment. As the oil pressure between the piston 520 and the piston chamber 511 increases, the pressure gradually compresses the elastic element 530, causing the piston 520 to move toward the top of the piston chamber 511 until the slide valve 300 abuts against the auxiliary cylinder wall 400.

[0056] As the amount of oil between the piston 520 and the bottom of the piston chamber 511 decreases, the oil pressure between the piston 520 and the bottom of the piston chamber 511 decreases. The elastic force of the compressed elastic element 530 gradually exceeds the oil pressure between the piston chamber 511 and the piston 520, thereby allowing the elastic element 530 to reset and drive the piston 520 toward the bottom of the piston chamber 511, thereby causing the slide valve 300 to move away from the auxiliary cylinder wall 400 and expose part of the pressure relief groove 210.

[0057] That is, the slide valve 300 is moved between the first position and the second position through the first drive mechanism 500 and the oil delivery system.

[0058] In some embodiments, the oil supply system can either supply oil to the piston chamber 511 through the first oil inlet 512 to increase the oil pressure between the piston 520 and the piston chamber 511, or it can extract oil from the piston chamber 511 through the first oil inlet 512 to reduce the oil pressure between the piston 520 and the piston chamber 511.

[0059] In some embodiments, the piston chamber 511 has a plurality of oil drain ports 513, which are spaced apart along the length of the piston chamber 511. Each oil drain port 513 is connected to an oil drain pipe, and the oil drain port 513 is connected to the oil supply system through the oil drain pipe. Each oil drain pipe is provided with a shut-off valve so that each oil drain port 513 can drain oil toward the oil supply system when the shut-off valve of the corresponding oil drain pipe is opened.

[0060] It should be noted that multiple oil drain ports 513 are spaced apart along the length of the piston chamber 511. The shut-off valves of the oil drain pipes corresponding to different oil drain ports 513 can be opened, so that the oil volume of the oil supply system into the piston chamber 511 is at the current oil drain port 513, thereby limiting the position of the piston 520 to the current oil drain port 513, and thus fixing the position of the slide valve 300.

[0061] Specifically, when the drain port 513 corresponding to the drain pipe of the open shut-off valve is closer to the top of the piston chamber 511, it means that the oil pressure between the piston 520 and the piston chamber 511 is greater, and the fixed position of the slide valve 300 is closer to the auxiliary cylinder wall 400. Conversely, it means that the fixed position of the slide valve 300 is farther away from the auxiliary cylinder wall 400.

[0062] In some embodiments, the oil delivery system comprises an oil tank located on one side of the cylinder block 100, an oil supply pipe connected to the first oil inlet 512, and an oil pump located in the oil tank. The oil pump is used to deliver oil from the oil tank to the space between the piston chamber 511 and the piston 520. The oil pump can also pump oil from the piston chamber 511 back into the oil tank. The oil pump is a bidirectional centrifugal pump.

[0063] In some embodiments, the oil delivery system includes the inner cavity of the cylinder body 100, an oil delivery pump, an oil delivery pipe, and a return oil cylinder 700 communicating with the inner cavity of the cylinder body 100. The end of each oil delivery pipe away from the oil outlet 513 is communicating with the inner cavity of the cylinder body 100. The oil delivery pump is disposed in the return oil cylinder 700. One end of the oil delivery pipe is communicating with the first oil outlet 512, and the other end of the oil delivery pipe is communicating with the oil delivery pump. The oil delivery pump is used to pump the oil in the return oil cylinder 700 to the piston chamber 511.

[0064] That is, the lubricating oil in the cylinder 100 is used as hydraulic oil to move the piston 520 through the oil supply system, and the lubricating oil in the return oil cylinder 700 is delivered to the piston chamber 511 through the oil supply pump. When the current position of the slide valve 300 is required, the shut-off valve on the corresponding oil drain pipe of a certain oil drain port 513 is controlled to open, so that the slide valve 300 is kept in the current position.

[0065] In some embodiments, the first drive mechanism 500 includes a base 510, a piston 520, and a connecting rod 540. The base 510 has a closed piston chamber 511. The piston 520 is movably disposed within the piston chamber 511. One end of the connecting rod 540 is connected to the piston 520, and the other end of the connecting rod 540 passes through the top of the piston chamber 511 and is connected to a slide valve 300. A first oil inlet 512 is provided at the bottom of the piston chamber 511, and a second oil inlet is provided at the top of the piston chamber 511. The oil delivery system respectively... Connected to the first oil inlet 512 and the second oil inlet, the piston 520 divides the piston chamber 511 into a first sub-chamber and a second sub-chamber. The first sub-chamber is the space between the piston 520 and the bottom of the piston chamber 511, and the second sub-chamber is the space between the piston 520 and the top of the piston chamber 511. Oil can be supplied to the first sub-chamber and pumped back to the oil supply system through the oil supply system and the first oil inlet 512. Oil can be supplied to the second sub-chamber and pumped back to the oil supply system through the oil supply system and the second oil inlet.

[0066] When the slide valve 300 needs to be fixed in the current position, the oil supply system is controlled to supply the same amount of oil to the first sub-chamber and the second sub-chamber, thereby ensuring that the oil pressure in the first sub-chamber and the second sub-chamber is the same, which can then fix the piston 520 in the current position, and thus fix the slide valve 300 in the current position.

[0067] When the slide valve 300 needs to be moved away from the auxiliary cylinder wall 400, oil can be discharged through the first oil inlet 512 and oil can be supplied through the second oil inlet, thereby pushing the piston 520 to move towards the bottom of the piston chamber 511, so that the slide valve 300 is moved away from the auxiliary cylinder wall 400.

[0068] When the slide valve 300 needs to be close to the auxiliary cylinder wall 400, oil can be supplied through the first oil inlet 512 and discharged through the second oil inlet, thereby pushing the piston 520 toward the top of the piston chamber 511, so that the slide valve is close to the auxiliary cylinder wall 400.

[0069] In some embodiments, the compressor 10 further includes a second drive mechanism 600, which is connected to the auxiliary cylinder wall 400 and is used to drive the auxiliary cylinder wall 400 to move along the length direction of the pressure relief groove 210.

[0070] Specifically, in some embodiments, a rack is provided on the outer wall of the auxiliary cylinder wall 400, and the second drive mechanism 600 includes a motor and a gear connected to the motor. The gear meshes with the rack on the auxiliary cylinder wall. By controlling the rotation of the motor, the auxiliary cylinder wall 400 is driven to move in the pressure relief groove 210.

[0071] Specifically, in some embodiments, the second drive mechanism 600 is a telescopic rod, which is directly connected to the auxiliary cylinder wall 400. The telescopic rod extends and retracts to drive the auxiliary cylinder wall 400 to move in the pressure relief groove 210.

[0072] The telescopic pole can be either an electric telescopic pole or a hydraulic telescopic pole.

[0073] In some embodiments, the compressor 10 further includes an intake port 101 and an exhaust port 102, a slide valve 300 is disposed near the exhaust port 102, and an auxiliary cylinder wall 400 is disposed near the intake port 101.
