The compressor is a machine that transports gas and increases the pressure of the gas. The main function of the compressor is to compress the gas and synthesize the process, and then carry out the gas transfer for the next process. The gas-to-equipment process requirements are very strict. The pulsation of the gas generated during the flow of the gas, which forms a certain resonance with the vibration of the pipeline, will bring great harm to the production. So how does the vibration come about?
The medium inside the pipeline used by the compressor for transporting chemical raw materials is mostly a fluid, that is, a gas or a liquid, and therefore the pipeline is divided into a gas pipeline and a liquid pipeline by the type of the internal medium. Since the fluid parameters in the pipe often change with time, it often causes the pipe to vibrate.
There are three main reasons for the vibration of the pipeline: 1) When the reversing valve in the hydraulic system is closed, the liquid flow in the pipeline is suddenly stopped, and the hydraulic shock occurs to cause the pipeline to vibrate; 2) The hydraulic shock generated by the hydraulic components controlled by the hydraulic system causes the pipeline to brake. Vibration is generated; 3) The liquid flows through the orifice, causing cavitation, causing the pipe to vibrate.
Airflow pulsation and pipeline vibration will bring significant safety hazards to the equipment. Airflow pulsation may result in reduced compressor volumetric efficiency, increased power consumption, and instrument failure. The mechanical vibration of the pipe can cause loose or fatigue damage to the pipe fittings and joints. The existence of these factors is an important aspect of the formation of safety hazards in chemical production. Therefore, it is necessary to ensure the normal operation of the compressor and its pipelines, which is the correct choice to prevent problems before they occur.
