Description

Technical Field

[0001] This utility model relates to the field of compressor sealing technology, and in particular to a high-efficiency sealing structure for a quick-install compressor. Background Technology

[0002] Compressors, as common mechanical devices, are widely used in many fields such as industrial production and refrigeration and air conditioning. With the continuous development of various industries, higher demands are being placed on the performance and reliability of compressors. High-efficiency compressors can improve production efficiency, reduce energy consumption, and achieve more precise temperature control in the refrigeration field, creating a more comfortable environment for people. At the same time, the sealing performance of the compressor is crucial for its normal operation; a good seal can prevent media leakage, improve the compressor's working efficiency, and extend its service life.

[0003] The commonly used method in the current technology is to use rubber gaskets, which are installed at the critical connection parts of the compressor. The rubber relies on elastic deformation to fill the gap and achieve a sealing effect. This method is simple, easy to implement, and low in cost, and is widely used in some low-pressure and normal-temperature operating conditions.

[0004] Regarding the aforementioned technologies, rubber gaskets are easily affected by a combination of factors such as temperature, pressure, and chemical media during long-term use. These factors work together to cause the rubber gaskets to age and deform. If they are not replaced regularly, the sealing performance of the rubber gaskets will decrease, increasing the risk of leakage. Utility Model Content

[0005] To improve the sealing effect of the sealing structure, this application provides a high-efficiency sealing structure for a quick-install compressor.

[0006] This application provides a high-efficiency sealing structure for a quick-installation compressor, employing the following technical solution: A quick-install compressor high-efficiency sealing structure includes a compressor housing and a rotating shaft. The rotating shaft passes through the compressor housing, and a seal is provided at one end of the rotating shaft. A connecting sleeve is provided on the outside of the rotating shaft, and the connecting sleeve is detachably connected to the rotating shaft. A driving component is provided on the outside of the connecting sleeve. A sealing cavity is formed between the compressor housing and the rotating shaft. The driving component is used to push the seal into the sealing cavity. An expansion component is provided on one side of the seal, which is used to drive the seal to expand.

[0007] By employing the above technical solution, the expansion component causes the seal to expand under pressure within the sealing cavity, pushing the seal to tightly adhere to the surface of the rotating shaft, forming an adaptive seal. This design can compensate for gap changes caused by manufacturing tolerances, thermal deformation, and long-term wear, ensuring continuous contact between the sealing surfaces, reducing the risk of leakage, and improving the sealing effect of the sealing structure.

[0008] Optionally, the drive unit includes two electric actuators, which are located on both sides of the connecting sleeve and are rotatably connected to the connecting sleeve.

[0009] By adopting the above technical solution, two electric actuators are symmetrically distributed on both sides of the connecting sleeve. The synchronous extension and retraction realize the uniform advancement of the seal, reduce the seal deviation caused by unilateral drive, ensure that the sealing surface is completely in contact with the rotating shaft, and improve the stability of the device.

[0010] Optionally, the expansion component includes a micro eddy current generator and a hose. The micro eddy current generator is fixed inside the compressor housing. The hose is located at one end of the micro eddy current generator and is connected to the micro eddy current generator. One end of the hose is connected to a seal. The micro eddy current generator is used to inject pressure into the seal, causing the seal to expand.

[0011] By adopting the above technical solution, the micro eddy current generator injects pressure into the seal to cause it to expand, which enables the seal to fit more tightly against the contact surface, fills any possible tiny gaps, effectively reduces gas or liquid leakage, improves the reliability of the seal, and ensures the stable operation of the compressor.

[0012] Optionally, two contacts are provided on one side of the seal, and a pressure sensor corresponding to the contacts is provided in the sealing cavity. The pressure sensor is electrically connected to a micro eddy current generator and is used to detect the pressure borne by the seal.

[0013] By adopting the above technical solution, the pressure sensor senses the pressure on the seal in real time through the contact element and transmits the data accurately to the micro eddy current generator. The micro eddy current generator dynamically adjusts the pressure injected into the seal based on the pressure data fed back by the sensor, thereby improving the flexibility of the device.

[0014] Optionally, a sealing ring is fixed inside the compressor housing, and the sealing ring is located in the sealing cavity.

[0015] By adopting the above technical solution, the sealing ring material has excellent elasticity and flexibility. After being installed in the sealing cavity, it can closely fit the contact surface between the compressor housing and the rotating shaft. After the sealing element enters the sealing cavity, the sealing ring and the sealing element are tightly attached, which further improves the sealing effect and reduces the probability of liquid leakage.

[0016] Optionally, a guide rod is provided on the outside of the connecting sleeve. The guide rod is rotatably connected to the connecting sleeve and can be extended and retracted. The end of the guide rod away from the connecting sleeve is fixedly connected to the seal.

[0017] By adopting the above technical solution, the presence of the guide rod provides a clear movement trajectory for the seal. Guided by the guide rod, the seal can accurately extend and retract along the direction of movement of the electric actuator, ensuring that the seal is always in the correct sealing position and will not deviate, thus preventing sealing failure and improving the stability of the device.

[0018] Optionally, a connecting ring is fixedly provided on the outer side of the rotating shaft, and a number of sealing teeth are fixedly provided on the outer side of the connecting ring, with the sealing teeth evenly distributed along the circumference of the connecting ring.

[0019] By adopting the above technical solution, during the rotation of the shaft, these sealing teeth can effectively reduce fluid leakage from the gap between the shaft and surrounding components, further improving the sealing effect. At the same time, when the shaft rotates at high speed or bears a large load, the connecting ring can evenly transmit the force to each sealing tooth, reducing the shaft from breaking or deforming due to excessive local stress, and ensuring its reliability during long-term operation.

[0020] Optionally, the connecting sleeve is provided with several screws along the circumference, and the screws pass through the connecting sleeve and are threaded to the rotating shaft.

[0021] By adopting the above technical solution, the screw and the shaft are connected by threads. This connection method can provide reliable mechanical fixing force. During the operation of the equipment, even if it is subjected to large vibration, impact or torque, it can effectively reduce the relative loosening or separation between the connecting sleeve and the shaft. When the equipment needs to be repaired or parts replaced, the screw connection method is easy to disassemble for repair or replacement, improving the convenience of use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The expansion element causes the seal to expand under pressure within the sealing cavity, pushing the seal to fit tightly against the surface of the rotating shaft, forming an adaptive seal, ensuring continuous contact between the sealing surfaces, reducing the risk of leakage, and improving the sealing effect of the sealing structure; 2. The presence of the guide rod provides a clear movement trajectory for the seal. Guided by the guide rod, the seal can accurately extend and retract along the direction of movement of the electric actuator, ensuring that the seal is always in the correct sealing position and will not deviate, thus preventing sealing failure and improving the stability of the device. 3. When the equipment needs to be repaired or parts replaced, the screw connection method facilitates disassembly for repair or replacement, improving the convenience of use.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses a high-efficiency sealing structure for a quick-install compressor. Example

[0029] Reference Figure 1 and Figure 2 A quick-installation compressor high-efficiency sealing structure includes a compressor housing 1 and a rotating shaft 2. The rotating shaft 2 passes through the compressor housing 1. One end of the rotating shaft 2 is provided with a sealing element 21. A connecting sleeve 3 is provided on the outside of the rotating shaft 2. The connecting sleeve 3 is detachably connected to the rotating shaft 2. Two electric push rods 32 are provided on the outside of the connecting sleeve 3. The two electric push rods 32 are symmetrically distributed on both sides of the connecting sleeve 3. A sealing cavity is formed between the compressor housing 1 and the rotating shaft 2. When sealing the sealing cavity, the electric push rods 32 are activated to push the sealing element 21 into the sealing cavity, so that the sealing element 21 seals the sealing cavity. The two electric push rods 32 achieve uniform advancement of the sealing element 21 through synchronous extension and retraction, reducing the deflection of the sealing element 21 caused by unilateral drive, ensuring that the sealing surface is completely in contact with the rotating shaft 2, and improving the stability of the device.

[0030] Reference Figure 2 An expansion element is provided on one side of the seal 21. The expansion element includes a miniature eddy current generator 22 and a hose 23. The miniature eddy current generator 22 is fixed inside the compressor housing 1. The hose 23 is located at one end of the miniature eddy current generator 22 and is connected to the miniature eddy current generator 22. One end of the hose 23 is connected to the seal 21. The miniature eddy current generator 22 uses the principle of fluid dynamics to generate eddies in the medium through high-speed rotation or vibration, converting the kinetic energy of the fluid into pressure energy. Pressure is injected into the seal 21 through the hose 23 to cause it to expand. This allows the seal 21 to fit more tightly against the contact surface, filling any possible tiny gaps, effectively reducing gas or liquid leakage, improving the reliability of the seal, and ensuring stable operation of the compressor. At the same time, it makes pressure transmission more flexible, allowing for better adjustment of the expansion degree of the seal 21 under different operating conditions to maintain a good sealing state.

[0031] Reference Figure 2 and Figure 3 A sealing ring 24 is fixed inside the compressor housing 1. The material of the sealing ring 24 has excellent elasticity and flexibility. After being installed in the sealing cavity, it can fit tightly against the contact surface between the compressor housing 1 and the rotating shaft 2. After the sealing element 21 enters the sealing cavity, the sealing ring 24 fits tightly against the sealing element 21, further improving the sealing effect and reducing the probability of liquid leakage.

[0032] Reference Figure 4 A guide rod 33 is provided on the outside of the connecting sleeve 3. The guide rod 33 is rotatably connected to the connecting sleeve 3 and is telescopic. The end of the guide rod 33 away from the connecting sleeve 3 is fixedly connected to the sealing element 21. When the electric push rod 32 pushes the sealing element 21 to move into the sealing cavity, the guide rod 33 retracts, providing a clear movement trajectory for the sealing element 21. Guided by the guide rod 33, the sealing element 21 can accurately move telescopically along the movement direction of the electric push rod 32, ensuring that the sealing element 21 can accurately reach the sealing cavity for sealing, reducing the probability of seal failure due to deviation, and improving the stability of the device.

[0033] Reference Figure 3 Two contact elements 25 are fixed on one side of the seal 21. A pressure sensor 26 corresponding to the contact element 25 is provided in the sealing cavity. The pressure sensor 26 receives the pressure data of the seal 21 in real time through the contact element 25. The pressure sensor 26 is electrically connected to the micro eddy current generator 22. After receiving the data, it accurately transmits it to the micro eddy current generator 22. According to the pressure data fed back by the pressure sensor 26, when the pressure of the seal 21 is insufficient, the micro eddy current generator 22 increases the injection pressure to make the seal 21 expand further and fill the potential leakage gap. When the pressure is too high, the injection pressure is appropriately reduced to avoid damage to the seal 21 due to excessive expansion. This achieves precise closed-loop control of the sealing pressure, dynamically adjusts the pressure injected into the seal 21, and improves the flexibility of the device.

[0034] Reference Figure 3 The connecting sleeve 3 is provided with a number of screws 31 along the circumference. The screws 31 pass through the connecting sleeve 3 and are threaded to the rotating shaft 2. This connection method can provide reliable mechanical fixing force. During the operation of the equipment, even if it is subjected to large vibration, impact or torque, it can effectively reduce the relative loosening or separation between the connecting sleeve 3 and the rotating shaft 2. At the same time, when the equipment needs to be repaired or parts replaced, the screw 31 connection method is easy to disassemble. Just turn the screw 31 to unscrew it, so that the connecting sleeve 3 is separated from the rotating shaft 2, and the parts on the connecting sleeve 3 can be repaired or replaced, improving the convenience of use.

[0035] Reference Figure 2 and Figure 3A connecting ring is fixedly provided on the outer side of the rotating shaft 2, and a number of sealing teeth 27 are fixedly provided on the outer side of the connecting ring. The sealing teeth 27 are evenly distributed around the circumference of the connecting ring. During the rotation of the rotating shaft 2, when the fluid enters the sealing teeth 27, the fluid velocity rises sharply and the pressure drops significantly when it enters the narrow tooth gap from the larger space, thereby reducing the amount of fluid leakage and further improving the sealing effect. At the same time, when the rotating shaft 2 rotates at high speed or bears a large load, the connecting ring can evenly transmit the force to each sealing tooth 27, reducing the possibility of the rotating shaft 2 breaking or deforming due to excessive local stress, and ensuring its reliability during long-term operation.

[0036] The implementation principle of a quick-installation compressor high-efficiency sealing structure in this application embodiment is as follows: During sealing, the electric push rod 32 pushes the sealing element 21 into the sealing groove. There is still a small gap between the sealing element 21 and the sealing groove. At this time, the micro eddy current generator 22 is activated to inject pressure into the sealing element 21 to cause it to expand, which enables the sealing element 21 to fit more tightly against the contact surface, fills the possible small gaps, effectively reduces gas or liquid leakage, and improves the sealing effect of the sealing structure.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
