The sucked gas in the water ring vacuum pump enters the space between the water ring and the impeller through the suction holes along the suction pipe and the joint. The crescent-shaped part on the right side increases gradually from small volume due to the rotation of the impeller, thus producing vacuum suction gas. Water ring vacuum pump with the impeller rotation, gas into the left crescent-shaped part. Because the impeller rotates eccentrically, the space is gradually reduced, and the gas is gradually compressed and pressurized. The gas and water enter the water tank through the outlet hole through the joint along the exhaust pipe, and are separated automatically and then released by the exhaust pipe. Waste water and air in the water ring vacuum pump are discharged into the water tank together.
The main parts of light multistage centrifugal pump, such as impeller, guide vane, pump shaft and outer cylinder, are made of stainless steel. All the overflow parts of the series are made of stainless steel. They have good corrosion resistance. They are driven by carbide bearings and mechanical seals and rigid coupling. They are small in size, light in weight, corrosion resistant, small in vibration, low in noise, small in floor area and long in service life. Beautiful appearance and other characteristics, especially the advantages of high efficiency and energy saving. Separator level gauge. The liquid level in the separator can be observed. If the automatic control of the liquid level is needed, the liquid level meter with signal output, automatic overflow or rehydration device should be installed. Separator pressure gauge. If pressure may occur in the separator, pressure gauges should be installed on the separator. Thermometer. If it is necessary to observe the inlet temperature of working fluid, a thermometer should be installed in the working fluid pipeline. Working fluid booster pump. If the working fluid supply of the pump is insufficient or the resistance of the working pipeline is large, the working fluid booster pump can be installed. Working fluid control valve. If the supply of working fluid may be too large, the control valve should be installed in the working fluid pipeline. Cavitation protection pipeline. If the suction pressure of the vacuum pump is close to the working fluid when it is used as a compressor, the balance pipeline and the corresponding valve accessories should be installed between the suction and exhaust pipelines of the compressor.
