A minute - know the structure of liquid ring vacuum pump and purposes

liquid ring vacuum pump ( Hereinafter referred to as water ring pump) Is a kind of coarse vacuum pump, a 2000 - can be obtained The limit of 4000 mpa vacuum, liquid ring vacuum pump and vacuum pump of vacuum can be up to 1 - unit 600 mpa. Water ring pump is suitable for conveying gas-liquid mixture. This pump can also be used for air pump and air compressor. It produces high absolute vacuum. Compression ratio depends on the pressure and rotating water ring the size and shape of the side walls outfalls. Water ring pump can be used as a compressor, also known as water ring compressor, belongs to low pressure compressor, the pressure range of 1 ~ 2 x 10 5 pa gauge pressure.

water ring pump initially used as a self-priming pump, then gradually used in many industry departments, such as petroleum, chemical industry, machinery, mining, light industry, medicine and food. In many industrial processes, such as vacuum filter, vacuum water diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum degassing, moisture regain and water ring pump is widely used. Due to the rapid development of vacuum technology, water ring pump in crude vacuum has received the attention. Because water ring pump, gas compression is isothermal, flammable and explosive gas and dust and water gas can be removed. Therefore, water ring pump application is increasing. Other suitable liquid can also be used as a working fluid of water ring vacuum pump. No matter use which kinds of working fluid, called liquid ring vacuum pump. Water ring vacuum pump is the most common type of liquid ring vacuum pump.

the most widely used of the pump. Pump body filled with just the right amount of water as working fluid. When the impeller rotates clockwise in the picture, impeller to jilt to jilt to water. Due to the effect of centrifugal force, according to the shape of the pump chamber, water formation thickness is roughly equal to the closing of the ring. The inner surface of the lower part of water ring coincided with the impeller wheel tangent to the inner surface of the upper water ring just contact with the tip of the blade ( In fact, the blade has certain insertion depth in water ring) 。 At this point, within the impeller wheel and water ring interface formed between crescent space, and the space be impeller blade into several with equal number of small cavity. If the starting point is the bottom of the impeller, the impeller rotating 180 degrees, the volume of small changes from small to big, small room with the suction connected on the face, at this time in gas, when the end of the suction chamber from the inlet; When the impeller to rotate, from large to small small room, make the gas is compressed; When small room and vent connected, gas from the eduction in pump. Above all, by changing the pump water ring pump cavity volume to achieve suction, compression and discharge, thus belongs to the variable volume pump. Liquid ring vacuum pump has simple structure, do not need to smoke exhaust valve, stable and reliable work, nothing inside the pump.

the friction surface is suitable for the filtration, vacuum drying, sterilization, pneumatic transportation, etc. It is also used in single stage or multistage fire pump or Marine pump, as vacuum pump, vane pump is full of water. In addition, the rotating speed of pump is relatively high. Generally speaking, the pump can be directly connected to the motor, don't need a speed reducer. Therefore, the use of the structure of the small size, can get large exhaust volume, and occupied area is small.
