500m3/H 2bw3161 Liquid Ring 2BV6161 Vacuum Pump Unit

Basic Info.

Product Description

Liquid ring vacuum pump is a kind of positive displacement vacuum pump, which generally uses water or other low saturated vapor pressure liquid as working fluid. Due to the structure of the liquid ring vacuum pump itself and the influence of the saturated vapor pressure of the circulating working fluid, the vacuum of the liquid ring vacuum pump is relatively rough. Generally, the ultimate pressure of the liquid ring vacuum pump is 2000~4000pa. If the air ejector is connected in series, the ultimate pressure of the liquid ring vacuum pump can reach 270~670pa. As the liquid ring vacuum pump has the advantages of simple structure, convenient manufacturing, reliable operation, simple operation and strong durability, it can pump corrosive gases, dusty gases and steam water mixed gases. Therefore, it is widely used in chemical industry, petroleum, pharmacy, food processing industry and light industry.

1. There is no metal friction surface in the pump, so it is unnecessary to lubricate the pump. The precision requirement of parts and components is not high, the structure is simple, the manufacturing is easy, the cost is low, the work is reliable, the failure is not easy to occur, and the maintenance is simple;2. The pump has a compact structure, high speed, and is generally a direct connection structure. Therefore, the pump is small in size and light in weight. With small structure size, large exhaust volume can also be obtained, and the floor area is relatively small;3. The water is generally used as the liquid ring, which is suitable for pumping toxic and harmful gases. Although the inhaled gas contains some water or condensable gas, it will not affect the performance of the pump;4. Compressed gas is isothermal, that is, the temperature of gas changes little during compression. In this way, when compressing flammable and explosive gases (such as gas, natural gas, acetylene, oxygen, hydrogen, etc.), no explosion or combustion accident will occur. This feature is particularly important in the application of chemical industry.
