[0033] Compressor 120, arranged on the upper part of the oil separator 110, a second opening is arranged at the bottom of the compressor 120, and the second opening is arranged corresponding to the first opening;
[0034] Power assembly 140, drivingly connected to the compressor 120, the power assembly 140 is arranged on the upper part of the oil separator 110, and is located on one side of the compressor 120;
[0035] Buffer 130, arranged between the first opening and the second opening, one end of the buffer 130 abuts against the compressor 120, the other end abuts against the oil separator 110, and a through hole is arranged in the middle of the buffer 130, and the through hole conducts and connects the oil separator 110 and the compressor 120.
[0036] By arranging an oil separator 110 and a compressor 120 on the upper part of the base 100, a stable layered structure is formed, ensuring the compactness of the equipment and the space utilization rate, and reducing the requirement for installation space; a buffer member 130 is arranged between the first opening and the second opening, and the through hole in the middle ensures the continuity of gas flow. The two ends of the buffer member 130 are respectively in contact with the compressor 120 and the oil separator 110, which can effectively absorb the vibration and impact during the operation of the compressor 120, significantly reducing the noise level of the equipment and improving the comfort of the working environment; the buffer member 130 is precisely adapted to the first opening and the second opening, enhancing the sealing performance of the entire system and ensuring the efficient operation of the equipment; the shock-absorbing equipment can reduce the wear between the various components of the equipment, thereby extending the service life of the screw compressor 120 and reducing the maintenance cost.
[0037] The buffer member 130 is a corrugated pipe. The corrugated pipe can effectively absorb the vibration energy generated during the operation of the compressor 120, reducing the vibration amplitude of the equipment. The corrugated pipe can adapt to temperature changes and slight displacements between the equipment, greatly improving the stability and reliability of the equipment. It can be understood that the buffer member 130 can also use a plastic hose, and the hollow plastic hose can play both a buffering role and a conduction role.
[0038] An end cover is arranged at the bottom of the compressor 120, and a first flange is arranged on the end cover. A second flange is arranged at one end of the buffer member 130, and the first flange and the second flange are mutually adapted. The corrugated pipe is fixedly connected to the compressor 120 through the first flange and the second flange. Through the mutual adaptation of the first flange and the second flange, the corrugated pipe is firmly fixed on the end cover at the bottom of the compressor 120, ensuring that the corrugated pipe will not be displaced under high load and vibration environments, and improving the stability and reliability of the connection.
[0039] A sealing gasket is arranged at the abutting position of the corrugated pipe and the oil separator 110, and the shape of the sealing gasket is mutually adapted to that of the end cover. It can further improve the sealing performance, effectively prevent the leakage of oil or gas, and improve the overall sealing performance of the system.
[0040] The corrugated pipe includes an outer pipe 160 and an inner pipe 150. The cross section of the outer pipe 160 is corrugated, and the outer pipe 160 wraps around the inner pipe 150.

The inner pipe 150 can form a closed channel to prevent the leakage of gas or liquid inside the compressor 120 and ensure the normal operation of the equipment.
[0041] The inner wall of the inner tube 150 is provided with a corrosion-resistant coating. The corrosion-resistant coating effectively blocks the corrosive substances that may be contained in the oil and gas generated during the operation of the compressor 120 from eroding the inner tube 150, reduces the oxidation and corrosion of the metal material, and thus significantly extends the service life of the bellows. It is understandable that the coating can be an epoxy paint coating or an acrylic paint, which has the characteristics of corrosion resistance, heat resistance, strong UV resistance, no solvent, and compliance with environmental protection requirements. Acrylic paint is generally applied using three types of paints: primer, middle paint and topcoat. After coating, it has excellent corrosion resistance and durability, and can greatly improve the service life of the bellows.
[0042] The outer edges of both ends of the bellows are provided with arc transition treatment. The arc transition can effectively disperse stress concentration and avoid the formation of sharp stress peaks at the ends of the bellows, thereby reducing the risk of material fatigue and cracks and enhancing the overall strength and life of the bellows. The outer sleeve of the bellows is provided with a stainless steel braided mesh sleeve. The stainless steel braided mesh sleeve provides additional mechanical protection for the bellows, enhances its physical strength, and enables the bellows to maintain structural integrity and stability when subjected to external pressure or impact.
[0043] A cushioning rubber pad is provided between the power assembly 140 and the oil separator 110. By reducing the impact of vibration on the oil separator 110, the cushioning rubber pad indirectly reduces the wear rate of internal parts, helps to extend the service life of the entire compressor 120 system, and reduces the maintenance frequency and cost. The cushioning rubber pad can be detachably installed at the bottom of the power assembly 140, and the cushioning rubber pad and the power assembly 140 are installed by snaps. The cushioning rubber pad can be quickly installed and removed without the use of tools, and can be completed by manual operation, which greatly saves time and labor costs.

The separator is used to improve the oil and gas recovery efficiency; the compressor 120 is installed on the oil separator 110, and a second opening corresponding to the first opening is provided at the bottom thereof for connecting with the buffer 130; the power assembly 140: is connected to the compressor 120 in a transmission manner, is located at the top of the oil separator 110, and is close to one side of the compressor 120, ensuring the high efficiency and stability of power transmission. The bellows includes an inner and outer double-layer structure, the cross section of the outer tube 160 is corrugated, and is wrapped outside the inner tube 150, and the inner side wall of the inner tube 150 is coated with a corrosion-resistant coating to resist the corrosion of the internal fluid and extend the service life. The outer edges of both ends of the bellows are subjected to arc transition treatment to reduce stress concentration and improve fatigue resistance. The outer sleeve of the bellows is provided with a stainless steel braided mesh sleeve to increase strength and wear resistance. The bottom end cover of the compressor 120 is provided with a first flange, which is matched with the second flange at one end of the bellows, and the flange connection ensures the stable fixation of the bellows and the compressor 120. A sealing gasket is provided at the abutment between the bellows and the oil separator 110, which matches the shape of the end cover and enhances the sealing of the connection part.
[0045] A buffer rubber pad is provided between the power assembly 140 and the oil separator 110 and is detachably connected to the bottom of the power assembly 140 by means of a snap-fit, thereby ensuring quick installation and disassembly, simplifying the maintenance process, and improving maintenance efficiency.
[0046] The effective combination of bellows and cushioning rubber pads significantly reduces the vibration and noise of compressor 120 during operation, and improves the comfort of the working environment. By reducing vibration and wear, and applying corrosion-resistant coatings, the service life of the equipment is extended and the maintenance cost is reduced. The design of snap-on installation and flange connection makes maintenance and replacement of parts more convenient and reduces downtime. The use of sealing gaskets ensures a tight seal at the connection parts, prevents leakage, and improves the safety of equipment operation. By reducing noise and leakage, a more environmentally friendly working environment is created, which meets the requirements of green production.
