[0001] The utility model relates to the technical field of compressors, in particular to a vibration reduction control device for a pipeline of a piston type compressor. Background Art

[0002] Piston compressors are widely used in many industrial fields, such as chemical, pharmaceutical, and food processing. The outlet pipelines of existing piston compressors are mostly connected by pipe welding. Under the influence of pressure fluctuations and vibrations, the pipeline system will be damaged, and the connection between the pipeline and valves, accessories, etc. will be loosened, causing cracks in the pipeline due to fatigue. In severe cases, a large amount of medium will leak, causing combustion and explosion. In addition, vibration will affect the suction and exhaust effects and reduce the efficiency of the unit.

[0003] Based on this, the causes and anti-vibration measures of piston compressor pipeline vibration were analyzed, and the following anti-vibration measures were proposed.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2As shown, the utility model provides a technical solution: a piston compressor pipeline vibration reduction control device, comprising a piston compressor body 1, a compressor exhaust pipeline 2 and an air supply pipeline 3 connected to the piston compressor body 1, the exhaust pipeline 2 and the air supply pipeline 3 are both equipped with metal bellows 4, the exhaust pipeline 2 is provided with two sections of metal bellows 4, the front end of the metal bellows 4 is connected to the exhaust pipeline 2 of the piston compressor body 1, the rear end of the metal bellows 4 is connected to a spherical tank 6, and an air supply valve 5 is provided between the two sections of the metal bellows 4. By installing the metal bellows on the terminal exhaust pipeline and the air supply pipeline of the piston compressor, the mechanical vibration generated during the operation of the piston compressor can be reduced and absorbed by the stainless steel bellows, thereby reducing the influence of the vibration generated during the operation of the piston compressor on the exhaust pipeline and the air supply pipeline.

The air supply pipe 3 is also fixedly connected to the metal bellows 4.

[0024] The utility model selects a bellows with suitable wave number, wall thickness and material according to the outlet pressure and flow of the piston compressor. The material of the bellows should have the characteristics of high pressure resistance and corrosion resistance, such as stainless steel, nickel alloy, etc. When installing the bellows: on the outlet pipeline (exhaust pipeline 2) of the piston compressor and on the air supply pipeline network (air supply pipeline 3). The bellows is reliably connected to the pipeline system, and welding, flange and other connection methods can be used to ensure the sealing between the bellows and the pipeline system. Adjust the compressor parameters: After installing the bellows, adjust the operating parameters of the compressor, such as compression ratio, exhaust volume, etc., to adapt to the system changes after the bellows are installed. At the same time, adjust the control logic of the compressor according to the actual situation to ensure the stable operation of the system.

Based on the test results, optimize and adjust the parameters of the bellows or the operating parameters of the compressor to improve the performance of the system.

[0026] Working principle: After the exhaust of the piston compressor enters the final stage cooler, the compressed gas passes through the metal bellows, which reduces and absorbs the mechanical vibration generated during the operation of the piston compressor. The compressed gas is sent into the pipeline through the air supply valve, and the vibration is further absorbed by the metal bellows installed in the air supply pipeline. The compressed gas is sent to the gas spherical tank.
