Liquid ring vacuum pump is a rough vacuum pump, which can be used as a compressor, so we also call it a liquid ring compressor, liquid ring vacuum pump was originally used for self-priming pumps, and then he gradually used to Petroleum, chemical, machinery, mining, light industry and other industries, and liquid ring vacuum pump in these areas has made very good results. So how does the liquid ring vacuum pump work? Liquid ring vacuum pump working principle Liquid ring vacuum pump in the pump body with the right amount of water as the working fluid. When the impeller rotates clockwise in the figure, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the lower part of the water ring is just tangential to the hub of the impeller. The upper inner surface of the water ring is just in contact with the top of the blade (in fact, the blade has a certain insertion depth in the water ring). At this moment, a crescent-shaped space is formed between the impeller hub and the water ring, and the space is divided into a plurality of small cavities equal to the number of the blades by the impeller. If the lower part of the impeller 0 ° as a starting point, then the impeller 180 ° before the rotation of the small chamber volume from small to large, and the end of the suction port communicating, when the gas is inhaled, when the inhalation end of the small cavity When the impeller continues to rotate, the small cavity becomes smaller and the gas is compressed; when the small chamber communicates with the exhaust port, the gas is discharged outside the pump. Through the above introduction, we can conclude that liquid ring vacuum pump is based on the change of pump volume to achieve the suction, compression and exhaust, so it belongs to the varactor vacuum pump. Liquid ring vacuum pump gas compression is isothermal, so it can be used to extract flammable, explosive gas, although the liquid ring vacuum pump in the use of engineering, but it can not hide its features, so in today's production It still has a wide range of applications.
