How the water ring vacuum pump works

The stainless steel water ring vacuum pump is a rough vacuum pump, which can obtain an ultimate vacuum of 2000~4000Pa and a series atmospheric injector of 270~670Pa. It can be used as a compressor, called a water ring compressor. It is a low-pressure compressor with a pressure range of 1~2×105Pa.

The water ring vacuum pump was originally used as a self-priming pump and was gradually used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry, medicine and food. In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum regain and vacuum degassing, etc., have been widely used.

Zhuocheng Pump

As shown in the figure: The pump body is filled 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 portion of the water ring is just tangent to the impeller hub, and the upper inner surface of the water ring is just in contact with the tip of the blade (actually the blade has a certain depth of insertion within the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into a plurality of small cavities equal to the number of blades. If the lower part of the impeller is 0°, the volume of the small cavity becomes smaller from 180° before the rotation, and it communicates with the suction port on the end face. At this time, the gas is sucked in, and when the inhalation is finished, the cavity is small. It is isolated from the suction port; when the impeller continues to rotate, the small cavity becomes larger and smaller, so that the gas is compressed; when the small cavity communicates with the exhaust port, the gas is discharged outside the pump.
