Description

Technical Field

[0001] The utility model relates to, in particular to an exhaust system structure of a compressor. Background Art

[0002] The exhaust system of existing household reciprocating refrigerator compressors is generally composed of a cylinder head, a valve plate, a crankcase exhaust hole, a high-pressure chamber, a cover plate assembly, etc. After being compressed, the gas is discharged from the compressor through the cylinder head, valve plate, crankcase exhaust hole, high-pressure chamber, cover plate assembly, exhaust pipe, etc. and flows to the refrigeration system. The exhausted gas is a high-temperature, high-pressure gas. Since the exhaust hole is relatively close to the cylinder hole, the processing of the exhaust hole is likely to cause deformation of the cylinder hole. During the exhaust process of the crankcase exhaust hole, the heat conduction of the high-temperature, high-pressure gas will cause the cylinder hole to deform, affecting the stability of the cylinder, and affecting the power and efficiency of the compressor.

[0003] The Chinese utility model patent with the announcement number CN206409356U proposes a suction and exhaust system structure of a piston refrigeration compressor, including a connecting rod, a piston pin, a piston, a crankcase, a valve plate, an exhaust valve plate, an exhaust stopper and a cylinder head. One end of the connecting rod is connected to the piston, and the piston is arranged in the crankcase. An exhaust hole is opened on the valve plate, and an exhaust valve plate and an exhaust stopper are arranged on the valve plate. An air suction hole is arranged on the cylinder hole wall of the crankcase. The distance between the opening position of the air suction hole and the end face of the crankcase can be: greater than 1 / 3 of the piston stroke and less than 1 / 2 of the piston stroke. The distance between the exhaust hole and the cylinder hole of this patent is too close, and the discharged high-temperature gas is easy to cause deformation of the cylinder hole.

[0020] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] Embodiment 1:

[0022] A compressor exhaust system structure, characterized in that it includes an exhaust system, the exhaust system includes a cylinder head 1, a cover plate assembly connected to the cylinder head 1, and an exhaust pipe 6 connected to the cover plate assembly, and the exhaust pipe 6 is installed on the outer wall of the exhaust system. The cover plate assembly of the utility model can reduce the exhaust holes on other modules, thereby avoiding deformation of the cylinder hole.

[0023] In the field of industry and machinery, the compressor is a key device used to compress gas or steam into a higher pressure state. As an important part of the compressor, the exhaust system is responsible for guiding the exhaust gas to the appropriate location. The utility model proposes an innovative exhaust system structure, which aims to solve the problems existing in the traditional exhaust system.

[0024] First, the key components of the exhaust system of the utility model include the cylinder head 1, the cover plate assembly and the exhaust pipe 6. The cylinder head 1, as one of the key components of the compressor, is connected with the cover plate assembly to form a complete exhaust system. The cover plate assembly is used to connect the cylinder head 1 with the exhaust pipe 6 and has the function of reducing the exhaust holes on other modules.

[0025] In a traditional exhaust system, exhaust holes are usually distributed on various modules, including cylinder head 1, cylinder block and other components. However, as the number of exhaust holes increases, the structure of the cylinder hole may be deformed, thereby affecting the stability and performance of the entire exhaust system. The utility model introduces a cover plate assembly to concentrate the exhaust holes on the cover plate assembly, thereby avoiding the necessity of setting exhaust holes on other modules, thereby effectively reducing the risk of cylinder hole deformation.

[0026] In addition, the installation position of the exhaust pipe 6 is also a key design feature of the utility model. In a traditional exhaust system, the exhaust pipe 6 is usually installed inside the exhaust system, which may cause friction and wear between the exhaust pipe 6 and other components, thereby affecting the service life of the exhaust system. The utility model installs the exhaust pipe 6 on the outer wall of the exhaust system, effectively reducing the contact with other components and improving the stability and durability of the exhaust system.

[0027] The cover plate assembly plays a vital role in the compressor exhaust system. The cover plate assembly includes a large cover plate 3 and a small cover plate 2 connected to the cylinder head. The coordinated effect of these two parts ensures the stability and functionality of the entire system structure.

[0028] First, as the main part of the cover plate assembly, the large cover plate 3 has multiple functions. First, it serves as a connecting medium between the cylinder head 1 and the exhaust pipe 6, effectively guiding the gas from the cylinder head 1 to the exhaust pipe 6, ensuring the normal operation of the exhaust system. Second, it plays a structural support role in the system, ensuring the overall stability of the exhaust system. Through appropriate material selection and processing technology, the large cover plate 3 can withstand the high temperature and high pressure generated when the compressor is working, ensuring the long-term stable operation of the system.

[0029] The small cover plate 2 is another important component of the exhaust system. The small cover plate 2 is fastened to the cylinder head 1 by screws to ensure the stability of the system structure and form a complete structure with the large cover plate 3.

[0030] The main function of the small cover plate 2 is to realize gas transportation, and to deliver the gas from the cylinder head 1 to the large cover plate 3. In order to ensure smooth and stable gas transportation, the small cover plate 2 is connected to one end of the large cover plate 3 through a short Bundy tube 4 to realize gas transportation between the small cover plate 2 and the large cover plate 3. This design can effectively reduce gas leakage and energy loss, and improve the efficiency and performance of the system.

[0031] In addition to the above functions, the cover plate assembly also has a certain degree of flexibility and adjustability. Since the compressor may produce different exhaust volumes and exhaust pressures under different working conditions, the cover plate assembly needs to be able to adjust and adapt according to the actual situation to ensure the stable operation of the system. This requires that the connection structure between the large cover plate 3 and the small cover plate 2 has a certain degree of adjustability and can maintain good sealing and connectivity under different working conditions.

[0032] In summary, the coordination of the large cover plate 3 and the small cover plate 2 in the exhaust system is an indispensable part of the entire system, achieving effective gas discharge and stable support of the system structure. Through reasonable design and optimization, the cover plate assembly can ensure the long-term stable operation of the exhaust system and provide reliable protection for the normal operation of the compressor.

[0033] The short Bundy tube 4 plays a vital role in the exhaust system. The shape of the short Bundy tube 4 is L-shaped. Its special L-shaped design provides a key advantage for the exhaust process. The short Bundy tube 4 can effectively prolong the residence time of the gas before discharge, so that the temperature of the gas can be gradually reduced, providing strong support for the stable operation of the system.

[0034] First, the L-shaped shape of the short Bundy tube 4 allows the gas to stay inside the pipe for a longer time before being discharged. When the compressor is running, the high-temperature gas generated enters the short Bundy tube 4 through the small cover plate 2 area, and then gradually flows along the L-shaped bend inside the pipe. Due to the curved design of the pipe, the gas will be reflected and diffused multiple times inside the pipe, which increases the contact time between the gas and the pipe wall, thereby accelerating the transfer and loss of heat. This design effectively prolongs the time the gas stays inside the pipe, allowing the temperature of the gas to gradually decrease, reducing the heat load of the system during the exhaust process.

[0035] Secondly, the L-shaped shape of the short Bondi tube 4 can also effectively reduce the jet speed when the gas is discharged, avoiding the impact and splashing phenomenon during exhaust. As the gas undergoes multiple reflections and diffusions inside the pipeline, its flow rate will gradually slow down, and finally be discharged from the end of the pipeline at a lower speed. In this way, the impact force and jet force generated during exhaust will be reduced, reducing the impact on the surrounding environment and equipment of the system, and protecting the safety and stability of the system.

[0036] In addition, the L-shaped shape of the short Bondi tube 4 can also effectively reduce noise and vibration during exhaust. Since the gas undergoes multiple reflections and diffusions when flowing inside the pipe, its flow process is relatively uniform and stable, reducing the turbulence and eddy currents generated during exhaust, thereby reducing the generation of noise and vibration. This is particularly important for application scenarios that require noise and vibration control, such as equipment operating in a silent environment or workplaces that are sensitive to vibration.

[0037] In summary, the special L-shaped design of the short Bundy tube 4 provides multiple advantages for the exhaust system, including extending the gas residence time, reducing the exhaust velocity, reducing noise and vibration, etc. Through reasonable design and optimization, the short Bundy tube 4 can effectively improve the performance and stability of the exhaust system and provide a reliable guarantee for the normal operation of the compressor.

[0038] The end of the large cover plate 3 away from the short Bundy tube 4 is connected to a long Bundy tube 5, and the other end of the long Bundy tube 5 is connected to the exhaust pipe 6, so as to realize the gas transportation from the large cover plate 3 area to the exhaust pipe. This design constitutes a key part of the exhaust system, which is aimed at effectively managing the discharge process of high-temperature gas. The unique design of the long Bundy tube 5 makes full use of its multi-section bending characteristics along the inner wall of the exhaust system, so that the gas can stay in the pipe for a longer time before being discharged, and has more time to slowly reduce the temperature, thereby reducing the heat impact on the system and its surrounding environment.

[0039] The long Bundy pipe 5 is bent in multiple sections along the inner wall of the exhaust system, so that the gas has more time to slowly cool down before being discharged. The multi-section bending design of the long Bundy pipe 5 is not only to increase the length of the pipe, but more importantly, through the process of bending and twisting, the flow process of the gas inside the pipe is made more complicated and slow. In this way, the residence time of the gas inside the pipe will increase accordingly, thereby increasing the contact time between the gas and the pipe wall, accelerating the transfer and loss of heat. This design can be regarded as an engineering art that aims to maximize the performance and stability of the exhaust system.

[0040] The large cover plate 3 is fastened to the exhaust system by screws to ensure the stability of the system structure. The fastening connection between the large cover plate 3 and the exhaust system is a key link to ensure the stability of the system structure. By using screws to firmly fix the large cover plate 3 to the exhaust system, it can effectively prevent the system from loosening or shifting during operation. This can not only ensure the normal operation of the system, but also reduce the risk of system failure or damage and extend the service life of the system.

[0041] In general, the combination of the large cover plate 3, the long Bondi pipe 5 and the exhaust pipe 6 constitutes a complete exhaust system with a well-designed and stable structure, which can effectively manage and control the exhaust process of high-temperature gas. This system can not only protect the equipment and the environment from heat, but also improve the performance and stability of the system, providing reliable support for industrial production and life.

[0042] Embodiment two:

[0043] The exhaust system structure of a compressor of the present application plays a vital role in various mechanical equipment and industrial applications. Its operating principle involves the effective management and discharge of high-temperature exhaust gas to ensure the normal operation of the equipment and the safety of the environment. The operating principle of the exhaust system will be described in detail below.

[0044] The core part of the exhaust system usually consists of a short Bundy pipe 4, a long Bundy pipe 5 and an exhaust pipe 6. First, when mechanical equipment or industrial production processes generate gases, these gases need to be effectively discharged through the exhaust system to avoid adverse effects on the equipment and the environment. The operating principle of the exhaust system is based on the following key steps:

[0045] 1. Gas collection: The gas is first collected into the exhaust system, which is usually guided to the inlet of the exhaust system through the pipe system inside the equipment to prepare for entering the exhaust pipe.

[0046] 2. Short Bundy pipe 4 treatment: After the gas enters the exhaust system, it will first be treated by the short Bundy pipe 4. The design of the short Bundy pipe 4 adopts a special L-shaped shape, which prolongs the time the gas stays inside the pipe and gradually reduces the temperature of the exhaust gas. This process helps to reduce the heat impact of the gas on the system and the surrounding environment.

[0047] 3. Long Bundy tube 5 delays discharge: The gas treated by the short Bundy tube 4 enters the long Bundy tube 5, where it flows along a multi-section curved path. The design of the long Bundy tube 5 allows the gas to stay inside the pipe for a longer time before being discharged, giving it more time to slowly lower its temperature. The purpose of this step is to delay the discharge time of the gas to further reduce the temperature and pressure during discharge.

[0048] 4. Exhaust pipe 6 discharge: The gas treated by the long bondi tube 5 finally enters the exhaust pipe 6, and the gas is discharged from the system through the exhaust pipe 6. The exhaust pipe 6 is usually connected to the outside of the equipment or discharged into the atmosphere through a chimney. During the discharge process, the temperature and pressure of the gas have been effectively controlled, reducing the adverse effects on the surrounding environment and equipment.

[0049] In summary, the operating principle of the exhaust system involves the collection, treatment and discharge process of gas. Through the design of the short Bundy tube 4 and the long Bundy tube 5, the gas discharge time is delayed and the temperature and pressure of the exhaust gas are controlled to ensure the stable operation of the system and the safety of the environment. Through reasonable design and optimization, the exhaust system can effectively manage high-temperature gas and provide reliable support for various mechanical equipment and industrial production.
