Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an interface connection joint, a compressor and a vehicle. Background Art

[0002] As the variety of compressors on the market continues to increase, their application in air conditioning, refrigeration, and other industrial fields is becoming increasingly widespread. The requirements for compressor pipe connections in different systems are also becoming more diverse. Currently, the connection methods between compressors and piping systems mainly include hose connections and rigid pipe connections. Hose connections are widely used in scenarios requiring flexible connections because the hose itself has high elasticity and can tolerate positioning deviations during installation to a certain extent. However, hose connections also have limitations such as insufficient pressure resistance and poor seismic performance, making them difficult to meet the needs of certain high-performance equipment.

[0003] In contrast, rigid pipe connections are widely used in systems requiring high reliability and vibration resistance due to their stable structure and superior pressure resistance. However, rigid pipe connections require high installation precision and have a low tolerance for positioning deviations in the pipe interfaces. During actual installation, the connection interface between the system and the compressor often fails to align due to slight deviations in position or angle. Such deviations can lead to connection failure or insufficient joint sealing, seriously affecting subsequent system commissioning and even reducing equipment reliability.

[0004] The existing technology lacks an interface connection solution that can both meet the high reliability requirements of rigid pipe connections and tolerate pipe interface deviations. Therefore, developing an interface connector for rigid pipe connections to address connection issues caused by interface deviations between compressors and systems has become an important technical issue.

[0035] The present invention is based on the theory of eccentric adjustment and sealing design in the field of fluid mechanics and mechanical connection. It adopts an eccentric adjustment structure. By setting the two end axes of a fluid channel to a non-coaxial state, the interface connection joint can compensate for the interface positioning deviation caused by the hard pipe connection method, thereby ensuring the connectivity of the fluid channel. Specifically, the adjustment member is essentially a cam structure. Through the rotation adjustment of its eccentric part, the path of the fluid channel is changed, thereby adjusting the relative spatial position relationship between different structural parts, so as to effectively eliminate the interface alignment problem caused by processing errors or installation deviations. In the present invention, the eccentric structure of the cam-type adjustment member allows for micro-displacement adjustment by changing the angle of the eccentric part, ensuring that the fluid channel interface is compensated in the radial or axial direction. This cam-based eccentric adjustment method makes it possible to flexibly deal with the interface deviation caused by the hard pipe connection method during the installation process, thereby achieving precise connection of the fluid channel. At the same time, the basic principle of the sealing design is to prevent the leakage of fluid along the joint connection by setting a sealing structure between the contact surfaces of the components, thereby ensuring the sealing performance of the system. This new utility model solves the problem of misalignment caused by interface deviation in rigid pipe connections by organically combining a cam-type eccentric adjustment structure with a sealing design. While achieving efficient fluid channel connection, it also ensures the sealing and mechanical stability between the joints, effectively improving the connection reliability and debugging efficiency between the compressor and the piping system, achieving the technical effects of interface error compensation and efficient sealing. Furthermore, the application of the cam structure provides the adjustment element with the advantages of simple structure, ease of processing and operation, further enhancing the system's ease of installation and applicability.

[0036] Figure 1 This is a cross-sectional view of the interface connection joint of an embodiment of the present utility model. Figure 2 1 is a front view and a cross-sectional view of a fixing member 100 according to an embodiment of the present invention. Figure 3 2 is a front view and a cross-sectional view of the adjusting member 200 of the embodiment of the present utility model. Figures 1 to 3As shown, the present invention provides an interface connection joint for solving the problem of the inability to align the interface between the compressor and the pipeline system due to the low tolerance of the positioning deviation of the hard pipe connection method. The interface connection joint of the embodiment of the present invention includes a fixing member 100 and an adjusting member 200. The fixing member 100 has a first fluid channel 110, and the second end 111 of the first fluid channel is connected to the management system, which is used to guide the fluid from the pipeline system into the interface connection joint and further flow to the compressor. The adjusting member 200 has a second fluid channel 210, and there is an offset between the axis 211a of the first end face of the second fluid channel and the axis 212a of the second end face of the second fluid channel. The design of the offset is based on the technical principle of eccentric adjustment, which is achieved by the eccentric part provided at the first end of the adjusting member 200. An eccentric channel is provided in the eccentric part, and the central axis of the eccentric channel does not coincide with the central axis of the eccentric part, and a step structure or a conical transition structure is formed between the eccentric channel and the second fluid channel 210, so that the fluid can transition smoothly and reduce fluid resistance. At the same time, the adjusting member 200 cooperates with the fixing member 100 through the eccentric portion. During the installation process, the path of the fluid channel is changed by adjusting the position of the eccentric channel, thereby compensating for the interface deviation between the compressor and the piping system, achieving an aligned connection between the two, and improving assembly accuracy and connection reliability. In addition, the design of the step structure or conical transition not only adapts to fluid channel interfaces of different diameters, but also effectively improves the stability of fluid flow and reduces energy loss. The adjusting member 200 is fixedly connected to the casing of the compressor through the fixing member 100. This fixing method not only ensures the stability of the adjusting member 200, but also provides reliable support for the arrangement of the sealing structure. The sealing structure is located between the fixing member 100 and the adjusting member 200 and is used to prevent leakage of the fluid at the interface connection. Its design is based on sealing theory. By applying sealing materials or structures between the contact surfaces of the two, it can maintain efficient sealing under actual working conditions. This embodiment of the utility model works together to address the misalignment issues caused by rigid pipe connections. The fixing member 100 provides basic support and guidance; the adjusting member 200 compensates for misalignment through an eccentric design, ensuring alignment; and the sealing structure ensures a tight seal at the connection. This structural layout enables an efficient and stable connection between the compressor and the piping system.

[0037] In some optional embodiments, the fixed connection method adopts a bolt connection, and the fixing member 100 is provided with a bolt hole 120 for installing the bolt, and the compressor housing is provided with a screw hole in the corresponding position. During the specific installation of this embodiment, the bolt is inserted through the bolt hole 120 and cooperates with the screw hole on the compressor housing. The fixing member 100 and the adjusting member 200 are fastened together with the compressor housing using the principle of threaded connection. The bolt connection structure has the advantages of simplicity, reliability and easy disassembly and assembly, and is suitable for scenarios requiring stable and high-strength fixing. In the embodiment of the present utility model, the bolt hole 120 on the fixing member 100 can have different geometric dimensions and structures, such as a circular hole or an elliptical slot, to adapt to different types of bolt installation requirements. In particular, when there are certain processing errors or position tolerances in the connection part, the elliptical slot design can improve the compatibility of the installation and further optimize the connection stability between the adjusting member 200 and the compressor housing. The preload force during the tightening process is controlled by the tightening degree of the bolt. Furthermore, the uniformity of the tightening force and the anti-loosening ability can be improved by adding washers or spring washers. This design is particularly important under dynamic load environments to prevent loosening due to vibration or temperature changes. The bolt material can be carbon steel, stainless steel or other high-strength alloy materials to meet the needs of different usage environments. In addition, although bolt connection is a typical connection method, the present invention is not limited to the form of bolt connection. The connection between the fixing member 100 and the compressor housing can also be achieved by welding, snap connection or other mechanical fixing methods. The specific selection can be adjusted according to the actual installation conditions and cost requirements. The use of bolt connection can provide a high-strength, reliable and easy-to-maintain fixing effect. The design of the bolt through hole 120 not only improves the convenience of the installation process, but also enhances the positioning accuracy of the component in actual use. Through the tightening action of the bolt, a stable and sealed connection is formed between the adjusting member 200, the fixing member 100 and the compressor housing, ensuring the reliability and service life of the system under high pressure or dynamic conditions.

[0038] In some optional embodiments, the adjusting member 200 is limited in the radial direction by bolts. Radial limitation refers to the limitation of the outer circumference of the adjusting member 200 by the bolts to ensure that the adjusting member 200 maintains the correct position during the connection process of the fixing member 100 or the compressor housing, thereby preventing the failure of the interface connection or the reduction of the sealing performance due to radial displacement. The adjusting member 200 is limited in the radial direction by the bolts mainly by utilizing the matching relationship between the geometric shape of the bolts and the surface of the adjusting member 200. When the bolt passes through the bolt hole 120 of the fixing member 100 and is fastened to the screw hole of the compressor housing, its circumferential structure is in close contact with the adjusting member 200, thereby limiting the displacement of the adjusting member 200 in the radial direction. This limiting method not only helps to improve the accuracy of the connection, but also prevents the adjusting member 200 from loosening due to external force or vibration during installation or operation. Furthermore, the bolt limitation can be achieved by setting an interference fit. In actual use, the fit between the bolt and the adjusting member 200 can be designed as a slight interference fit, so that the bolt can achieve radial limitation through a certain elastic deformation. Bolt limiting can also be achieved by adopting a multi-point limiting structure. In actual use, multiple limiting contact surfaces corresponding to the bolts are set on the outer periphery of the adjusting member 200 to improve the stability and reliability of the limiting. In an embodiment of the present utility model, the radial limiting method is not limited to the direct contact limiting between the bolt and the adjusting member 200. For example, the limiting mechanism can also be achieved by an elastic retaining spring, a locating pin or other mechanical structure, and its specific selection can be adjusted according to actual needs and design conditions. Through radial limiting, the adjusting member 200 can maintain a stable axial and circumferential position during installation and operation, effectively avoiding pipeline connection deviation or sealing failure problems caused by radial displacement. Compared with the design without limiting, this structure significantly improves the stability and durability of the interface connection, simplifies the alignment operation during the installation process, and reduces the manufacturing and maintenance costs in actual application. The diversity of the limiting structure and the flexibility of material selection further expand the scope of application of the design, which is suitable for achieving high-precision connection between the compressor and the pipeline system under various complex working conditions.

[0039] In some embodiments, the diameter of the bolt through hole 120 includes at least the diameter and offset of the bolt. In this design, the bolt through hole 120 not only needs to meet the basic requirements of the bolt passing through and tightening, but also needs to provide additional space to accommodate the offset of the adjusting member 200, thereby ensuring that the adjusting member 200 can be flexibly adjusted to the ideal position during the installation process. The bolt through hole 120 is usually a hole for the fastening bolt to pass through. The design of its diameter must meet the bolt assembly requirements and avoid interference problems caused by insufficient hole size. On the basis of considering the basic passability of the bolt, the embodiment of the present utility model further adds the influencing factor of the offset, so that the diameter of the bolt through hole 120 not only meets the basic function of fastening connection, but also can adapt to the offset of the adjusting member 200 for position adjustment. According to the design principle of the present utility model, the calculation formula of the diameter d of the bolt through hole 120 of the fixing member 100 is:

[0040] d=d 标准 +2r+design margin

[0041] Where: d 标准 is the size of the through hole designed according to the nominal diameter of the bolt in the conventional fixing part 100; r is the offset of the adjusting part 200; the design margin is the additional adjustment space provided (usually 0.3 to 0.5 mm) to accommodate processing errors and assembly requirements. In the embodiment of the present utility model, the design of the diameter of the bolt through hole 120 is not limited to a specific size or shape. The user can adjust the shape of the through hole and the design margin according to specific usage requirements, which should still be considered to fall within the scope of protection of the present utility model. By optimizing the design of the diameter of the bolt through hole 120, the utility model successfully solves the interference problem that may arise when the eccentric structure of the adjusting part 200 is connected to the fixing part 100 in the prior art, and effectively improves the installation flexibility of the adjusting part 200. At the same time, the design significantly reduces the dependence of the assembly on processing accuracy, improves the accuracy of the interface connection, and enhances the overall stability and reliability of the interface.

[0042] In some optional embodiments, the second end of the fixing member 100 is provided with a flange structure 130, and the opening diameter of the flange structure 130 is larger than the diameter of the second fluid channel 210. Specifically, the flange structure 130 refers to a circle of outwardly expanding annular protrusions provided on the second end of the fixing member 100, which contacts the second end face 212 of the second fluid channel of the adjusting member 200 to form a mechanical contact sealing surface. The opening diameter of the flange structure 130 is larger than the diameter of the second fluid channel 210, which is used to achieve better connection and sealing functions. The flared shape of the flange structure 130 can effectively prevent interception between the contact surfaces of the fixing member 100 and the adjusting member 200, ensuring that the fluid can flow smoothly. Specifically, the opening diameter of the flange is larger than the diameter of the second fluid channel 210, which avoids the problem of increased resistance to fluid flow or reduced flow during connection. At the same time, the structural design of the flange can also enhance the mechanical strength of the connection, prevent the interface from loosening or leaking under high pressure or vibration conditions, and improve the durability and reliability of the system. During specific implementation, the diameter of the flange needs to be designed according to the size of the second fluid channel 210 and the fluid circulation requirements, so that the opening diameter of the flange is at least larger than the diameter of the second fluid channel 210 to ensure smooth flow of the fluid. In addition, the design of the flange is not limited to the traditional annular structure. Flanges of different shapes can be used according to actual needs, and the specific flange structure 130 can be appropriately adjusted according to the actual application scenario and fluid characteristics. In addition, the size, thickness, etc. of the flange structure 130 can also be set according to specific system requirements. By providing the flange structure 130 at the second end of the fixing member 100, the stability and sealing of the interface connection can be effectively improved, the interception phenomenon during the fluid circulation process can be prevented, and the smooth flow of the system fluid can be ensured. This design not only enhances the mechanical strength of the connecting components and improves the pressure resistance of the interface, but also further optimizes the sealing performance, reduces the risk of fluid leakage, and improves the reliability and long-term stability of the entire system. At the same time, the introduction of the flange structure 130 can also simplify the connection process, improve assembly efficiency, and reduce the complexity of system debugging.

[0043] In some optional embodiments, the sealing structure between the fixing member 100 and the adjusting member 200 is configured as a radial seal or an end-to-end seal. The radial seal refers to a contact surface between the eccentric portion of the first end of the adjusting member 200 and the fixing member 100 being arranged in the radial direction of the first fluid channel 110 or the second fluid channel 210, and sealing is achieved by arranging a seal on the contact surface. Specifically, the seal is arranged at a fitting position between the inner circumferential surface of the eccentric portion and the outer wall of the fixing member 100. The seal can be a sealing ring or other sealing structure suitable for radial sealing. The end-to-end seal is achieved by arranging a sealing structure between the end face of the eccentric portion of the adjusting member 200 and the end face of the fixing member 100. The sealing structure can adopt a flat sealing gasket, a metal ring seal or other structural forms suitable for end-to-end sealing. Through the above structure, the radial seal mainly relies on the elastic deformation of the seal in the radial direction to achieve the sealing effect, and is suitable for the case where there is an annular gap between the eccentric portion and the fixing member 100, ensuring that the fluid does not leak along the gap. The end-to-end seal forms a sealing effect through the contact pressure between the seal and the two end faces. It is suitable for scenarios where the eccentric part and the end face of the fixed part 100 are tightly matched. Radial seals and end-to-end seals can also be set at the same time. By setting up a sealing structure with radial seals or end-to-end seals, it is possible to effectively prevent the leakage of fluid between the fixed part 100 and the adjusting part 200, ensure the sealing performance of the fluid channel, and improve the stability and reliability of the system operation. At the same time, the selective design of the sealing structure makes the utility model more flexible in application, and can select the appropriate sealing method according to the specific working conditions, thereby further optimizing the sealing effect and extending the service life.

[0044] In some optional embodiments, the sealing structure is realized by a sealing groove and a sealing ring, wherein the sealing groove is provided on a contact surface between the fixing member 100 and the adjusting member 200. Specifically, as Figure 2As shown, the sealing groove 140 can be set on the contact surface of the fixing member 100, or can be set on the contact surface of the adjusting member 200, or a sealing groove can be formed together at the contact portion between the two. The cross-sectional shape of the sealing groove can be rectangular, trapezoidal, semicircular or other shapes suitable for embedding a sealing ring. The sealing ring embedded in the sealing groove can be an O-ring, a square sealing ring, a V-ring or other structural forms suitable for fluid sealing. The material of the sealing ring can be selected according to the operating conditions. For example, rubber (such as nitrile rubber, fluororubber), polytetrafluoroethylene (PTFE), metal sealing ring, etc. can be used to meet the sealing requirements of different temperature, pressure and medium environments. In a specific embodiment, the sealing ring is embedded in the sealing groove to form a sealing area between the contact surfaces of the fixing member 100 and the adjusting member 200. When the adjusting member 200 and the fixing member 100 are installed by matching, the sealing ring undergoes slight elastic deformation under the action of pressure, thereby producing a sealing effect between the contact surfaces to prevent leakage of the fluid medium. In addition, in some optional embodiments, a double-channel sealing ring can be provided in the sealing groove to improve the reliability and redundancy of the seal; or a pre-pressed seal can be achieved through an interference fit between the sealing ring and the sealing groove to further improve the sealing effect. By adopting a sealing groove in combination with a sealing ring, efficient sealing between the fixing member 100 and the adjusting member 200 is achieved, effectively preventing leakage of the fluid between the contact surfaces and improving the reliability of the sealing structure. At the same time, the structure is simple in design, easy to process and install, and can flexibly select the shape and material of the sealing ring according to the actual use environment to adapt to the sealing requirements under different pressure, temperature and medium conditions. In addition, by providing a sealing groove between the contact surfaces, the sealing ring can have a better positioning effect, avoiding displacement of the sealing ring during installation and use, and further improving the stability and durability of the sealing structure.

[0045] In some optional embodiments, the adjusting member 200 is made of metal or high-strength plastic, and the fixing member 100 is made of metal. The adjusting member 200 is a component used to adjust the fluid channel connection between the compressor and the piping system. Its function is to compensate for pipeline alignment issues caused by installation errors or system deviations. In embodiments of the present invention, the adjusting member 200 can be made of metal materials such as aluminum alloys or stainless steel. Metal materials have high strength, rigidity, and corrosion resistance, making them suitable for applications that require high pressure or harsh environments. The metal adjusting member 200 can ensure the stability and durability of the connection, preventing connection failure due to corrosion or deformation during long-term use. The adjusting member 200 can also be made of high-strength plastics, such as glass fiber reinforced plastics, polycarbonate, polyamide, and other engineering plastics with high tensile strength, fatigue resistance, and low cost. These materials have better processing properties while maintaining a certain strength, are lightweight, and are low in cost, making them suitable for applications where weight and cost are important. High-strength plastics also have a certain degree of chemical resistance, making them suitable for applications in certain special fluids or environments. The fixing part 100 is connected to the piping system and is used to fix the adjusting part 200 to the compressor housing. Therefore, its material needs to have high mechanical strength and corrosion resistance. Metal materials such as steel, stainless steel, aluminum alloy, etc. When connected to the adjusting part 200, the metal fixing part 100 can provide strong mechanical support, ensuring the long-term stable operation of the system and avoiding loose interfaces or seal failure due to material fatigue or deformation. In addition, metal materials generally have good thermal conductivity, which can effectively dissipate heat during the operation of the compressor and prevent overheating and damage to components. In different application scenarios, the materials of the adjusting part 200 and the fixing part 100 can be selected according to actual needs. If the application is in a cost-sensitive low-pressure environment, a high-strength plastic adjusting part 200 can be selected, while in a high-temperature or high-pressure environment, a metal adjusting part 200 is more suitable. At the same time, in an environment where the fixing part 100 is subjected to large external forces, high-strength metal materials should be preferably selected to improve the stability of the connection part. By selecting metal or high-strength plastic for the adjustment member 200 and metal for the fixing member 100, the present invention provides an interface connector that functions effectively under various operating conditions. The choice of metal ensures high strength, corrosion resistance, and long-term stability of the connection, while the use of high-strength plastic reduces component weight and manufacturing costs while maintaining good mechanical properties. This design ensures the stability and sealing of the interface connection while meeting the requirements of diverse operating environments, avoiding interface leakage, deformation, or connection failure caused by improper material selection, thereby improving the performance and reliability of the entire system.

[0046] In some optional embodiments, the offset is 2 mm to 4 mm. The offset refers to the offset between the axis 211a of the first end face of the second fluid channel in the adjusting member 200 and the axis 212a of the second end face of the second fluid channel. The first end face 211 of the second fluid channel is the cross-section that connects to the fluid channel interface of the compressor housing, and the second end face 212 of the second fluid channel is the end face at the bottom of the eccentric groove. The offset in the embodiments of the present invention is designed to compensate for misalignment of the pipeline interface between the compressor and the piping system due to installation errors, inherent processing errors, poor assembly workmanship, or other factors. Generally, an offset of 2 mm to 4 mm can effectively mitigate slight deviations that may occur during actual installation, thereby ensuring stable operation of the connector. In actual use, the offset is designed to be 2 mm to 4 mm, and the specific value can be adjusted according to the specifications of different compressors and piping systems. In some applications with high precision requirements, a smaller offset (e.g., 2 mm) may be selected to ensure higher alignment accuracy. For some applications where larger installation errors are allowed, the offset can be appropriately increased to 4 mm to ensure that a certain amount of alignment error can be tolerated. In this embodiment, the offset of 2 mm to 4 mm is a typical range of the design, but it is not an absolute limitation. The specific offset can be flexibly adjusted according to actual needs and system accuracy requirements. For example, under some relatively loose installation conditions, the offset can be appropriately increased, even reaching 5 mm or higher. By designing an offset of 2 mm to 4 mm in the adjustment member 200, the utility model can effectively solve the problem of misalignment of pipeline docking caused by installation errors between the compressor and the pipeline system. The design within this offset range can not only tolerate positioning errors in actual applications, but also ensure the smooth flow of the fluid, avoiding pipeline leakage or poor fluid flow caused by misalignment in traditional hard pipe connection methods. Through this design, the installation process becomes more flexible, reducing the strict requirements for installation accuracy, thereby improving the reliability and production efficiency of the entire system.

[0047] Figure 4 Schematic diagram of the compressor of the present utility model embodiment. Figure 4As shown, an embodiment of the present invention also provides a compressor, comprising a housing assembly 300 and the above-mentioned interface connector. The housing assembly 300 is provided with a fluid interface, and the interface connector is fixedly connected to the housing assembly 300 and connects the fluid interface to the pipeline system. By using the above-mentioned interface connection scheme, the interface connector effectively solves the problems of difficult installation and unstable connection caused by misalignment of the pipeline interface in traditional hard pipe connections. The interface connector is used to connect the compressor and the pipeline system. This connection usually occurs between the compressor's intake and exhaust ports and the system's hard pipes. The compressor is connected to the pipeline system through the fluid interface to transmit gas or liquid fluid. The connector plays a role in guiding the fluid in this process, ensuring that the gas or liquid can flow stably from the compressor to the pipeline system and can withstand pressure fluctuations that may occur in the system. In an embodiment of the present invention, the housing assembly 300 of the compressor and the fixing member 100 of the interface connector are connected by a mechanical fixing method. The housing assembly 300 is usually the outer shell of the compressor, providing mechanical support and protection. It is provided with fluid interfaces, through which the fluid is connected to the pipeline system. The housing assembly 300 in this feature refers to the various parts that make up the compressor housing, including the frame and housing that support the compressor's internal components. This design allows the connection between the compressor housing and the interface connector to form a reliable fluid channel, effectively transmitting gas or liquid. In the present invention, the interface connector can be connected to the compressor housing assembly 300 through a fixed connection secured by a fixing member 100. This fixed connection can also be achieved through bolting, welding, or other suitable mechanical connection methods. This connection method ensures a stable and secure connection between the interface connector and the compressor housing, preventing loosening due to external forces or system vibration. This design effectively improves the reliability of the connection and avoids leakage caused by a loose connection. The fluid interface of the interface connector mates with the fluid interface of the compressor housing assembly 300, connecting the compressor's fluid output to the output or input of the piping system through this interface. These interfaces typically utilize a sealed structure, such as a sealing groove and a sealing ring, to prevent fluid leakage during flow. Precise alignment of the fluid interfaces is crucial for improving system efficiency and ensuring safe fluid transmission. This design not only reduces installation difficulty but also improves the sealing and reliability of the overall system. The design of the aforementioned interface connectors is tolerant to a certain degree of misalignment. With the aid of adjustment member 200, this effectively resolves issues arising from misalignment between the compressor intake and exhaust ports and the piping interface. Specifically, adjustment member 200, through its designed offset, adjusts the position of the connectors based on actual installation conditions, ensuring a smooth connection between the piping system and the compressor, thus avoiding unstable connections or leaks caused by misalignment.

The vehicle may further comprise a refrigeration system, the refrigeration system comprising a compressor, and the refrigeration system being used to provide cold air or hot air into the vehicle body, thereby ensuring the comfort of the environment within the vehicle.

[0049] The present invention proposes an improved technical solution to the problems existing in the prior art. Through the technical solution of the present invention, the connection between the compressor and the piping system becomes more flexible and efficient, and can effectively overcome the problems caused by installation errors and inaccurate positioning in traditional hard pipe connections. The design of the interface connection joint enables the system to tolerate a certain docking deviation, ensuring that the system can operate normally under various practical conditions. Due to the design offset and sealing structure, the connection between the piping system and the compressor has higher stability and reliability, avoiding problems such as leakage and loosening, and improving the overall performance and operating efficiency of the system.
