Water ring vacuum pump is mainly used in the formation of coarse vacuum. It is widely used in chemical, petroleum, pharmaceutical, paper making and so on because of its advantages of isothermal compression, insensitivity to dust, and the ability to absorb liquid or large amounts of water vapor.

Water ring vacuum pump can also use other liquid as working fluid, also known as liquid ring vacuum pump, this paper describes the water as working fluid.

Water ring vacuum pump in the consumption of electricity at the same time, but also consume water. For a long time, people do not know much about the characteristics of the water ring vacuum pump, so they often ignore the energy saving and water saving. According to the operating characteristics of the water ring vacuum pump under different working conditions, this paper introduces how to use the intelligent control method to make the water ring vacuum pump run in the most economical condition.

The working principle of 2 water ring pump is the working principle of water ring vacuum pump, the impeller is eccentrically mounted on the pump body close to the shape of the impeller when running to a certain speed, the centrifugal force, the pump body of water to the circumferential direction away, forming a close to the inner wall of the pump body water ring.

When the impeller moves from A to B, the air cavity surrounded by the two blades and the hub and the inner surface of the water ring increases gradually. When it is transferred from C to A, the volume of the corresponding air chamber is changed from large to small, so that the original gas is compressed. When the pressure reaches the outside pressure, the gas is discharged.

Water ring vacuum pump in the working process, the suction port is connected with the pumping system, the system of gas suction, vacuum formation. Exhaust side in the exhaust process will also bring out the work of water. To continuously provide working water to the vacuum pump.

3 suction change of vacuum constant mass flow control and energy saving in some conditions, the gas mass flow generated by the system is the same, if the process requirements in different period to form different vacuum gas, according to the thermodynamic equation of state:! "% if the above is regarded as mass flow (kg/min)," the volume flow rate (m3/min). In general, the temperature is fixed. When the mass flow is a fixed value, the absolute pressure! The smaller the volume, the greater the value (the gas constant).
