Description
Technical Field
The invention relates to the technical field of compressors, in particular to a double-air-inlet pulsation buffer.
Background
Reciprocating piston compressors and their piping systems often exhibit vibrations during operation. This is because the suction and discharge processes of the reciprocating piston compressor are not a continuous process, but intermittent and periodic. Therefore, the pressure of the gas in the pipeline is not stable, the exhaust pressure fluctuates up and down, and the fluctuating pressure is periodic and is generally called pulsating pressure.
The gas in the pipeline has natural frequency, once the natural frequency of the compressor falls within the range of the resonant frequency of the gas, the gas in the pipeline resonates, and the pulsating pressure theoretically reaches infinity. The pulsating pressure generates large exciting force at the turning or variable cross section (such as elbow, reducing pipe, tee joint, inlet and outlet of container, etc.) in the pipeline, which excites the forced vibration of pipeline, which is the mechanical vibration of pipeline system.
If the natural frequency of the compressor falls within the natural frequency of the mechanical system of the pipeline, the pipeline is vibrated violently; the strong vibration of the pipeline can loosen and crack the pipeline accessories, particularly the connecting parts of the pipeline, the connecting parts of the pipeline and the accessories and the like, and the strong vibration causes leakage at a light rate and explosion at a heavy rate due to the cracking, thereby causing serious accidents.
The traditional double-air-inlet pulsation buffer is not internally provided with an internal part, and the air pulsation generated by the air inlet I and the air inlet II can be superposed and enhanced inside the container, so that stronger air pulsation and exciting force are generated in the container, and the buffer and a connecting pipeline thereof strongly vibrate, and serious safety accidents can be caused if the strong vibration is not solved in time.

Before describing embodiments of the present invention in detail, the present invention will be described in an application environment. The technology of the invention is mainly applied to compressors, in particular to a buffer applied to a reciprocating piston type compressor.
Fig. 1 shows a schematic structural diagram of a conventional double-inlet pulsation damper, in which airflow entering a buffer cavity 20 from a first inlet 12 and a second inlet 13 is superimposed and enhanced in the buffer cavity 20, so that stronger airflow pulsation and excitation force are generated in the buffer cavity 20, and strong vibration of the damper and a connecting pipe 15 thereof is caused, and if the airflow pulsation is not solved in time, a serious safety accident is caused.
To solve the problem of pipeline vibration, the vibration cause must be solved from the source. Firstly, large pressure pulsation generated in a pipeline is avoided, and the solution is to adjust the natural frequency of an air column in the pipeline to ensure that the natural frequency of a compressor does not fall within the resonance range of the air column, so that the generation of large exciting force is avoided. In addition, the problem of avoiding large mechanical vibration of the pipeline is to adjust the mechanical natural frequency of the pipeline so that the natural frequency of the compressor does not fall within the mechanical natural frequency resonance range of the pipeline. Because the exciting force of the pipeline is always present and cannot be eliminated, and the compressor needs to generate vibration when working, an exciting source is also provided for the pipeline, and the mechanical natural frequency of the pipeline also needs to be adjusted after the natural frequency of the gas column is adjusted.
Referring to fig. 2, fig. 3 and fig. 4, the present invention provides a dual intake port pulsation damper, including:
