The water ring vacuum pump can obtain the ultimate vacuum of 2000~4000Pa, and the series air ejector can reach 270~670Pa. The water ring pump can also be used as a compressor, which is called a water ring compressor. It is a compressor with low pressure, and its pressure range is 1~2 x 105Pa meter pressure.
Water ring vacuum pump is a kind of coarse vacuum pump, it can get the limit of vacuum subject to structure and the working environment, and the current research about its power can be represented there are three ways of its power, to learn about below.
1. The unit power pumping capacity is used to indicate the energy efficiency of the pump.
2. The energy consumption power of the unit is represented by the power consumption of the unit air, which is the energy efficiency of the water ring vacuum pump.
3. representation efficiency value, efficiency value representation is expressed as a percentage of gas isothermal compression power ratio of total consumed power, in general, after the water ring vacuum pump compression, gas from inlet to outlet temperature of 2 ~ 5 degrees, so the water ring vacuum pump pumping gas can be regarded as the process of isothermal compression process.
