Pump oil pump body 
 Pump the water ring vacuum pump 
 Water ring pump is a liquid water as the working liquid ring pumps, a simple structure, reliable, easy operation and maintenance, and wide range of uses, suitable for pumping solid particles, not in water, the temperature in the - 10 ~ 60 ℃ range of gas, paper making, tobacco, food, textile, metallurgy, coal and chemical industry as vacuum dewatering, vacuum drying, vacuum filtration and pressure feed gas the ideal product. 
 Produced water ring vacuum pumps and compressors, as shown in product specifications and performance parameters, performance parameters listed in the table under standard conditions for the following properties: 
 (1) atmospheric pressure: 101.33Kpa 
 (2) inhalation gas is air, the temperature is 20 ℃, relative humidity 70% 
 (3) working temperature of 15 ℃ 
 Second, the main structure that 
 I produced a water ring vacuum pumps and compressors, there are two structural forms: 
 1. Axial single action of water ring vacuum pumps and compressors. 
 2. Radial dual role of water ring vacuum pumps and compressors. 
 Seal packing seal. 
 Drive with flexible coupling or belt drive transmission. 
 Third, the working principle 
 As the relative eccentric impeller and pump body, so when the impeller rotating water ring formed between the impeller hub and they formed a crescent-shaped space, and is separated into a number of blades pass each other, ranging from the closed chamber volume, with the impeller rotation, when the closure of small to large volume of the chamber, the so interlinked with the suction port, you will inhale the gas, when the closed chamber volume to low, the gas will be compressed, compressed to a certain extent, it vents the same, you can exhaust gas, the process (suction, compression, exhaust) repeated continuously, pumping could be achieved (compressed) gas purposes. Must be able to a certain pressure (typically 78-147kpa gauge) continuous water supply to the pump to supplement the water ring consumption. After the cooling water should be recycled, water quality should ensure that no corrosion and no scaling.
