Liquid ring vacuum pump is mainly used for the formation of rough vacuum. Because of its close isothermal compression, insensitive to dust, inhaled gas can be entrained with liquid or a large number of water vapor, etc., in the power, petrochemical, pharmaceutical, paper and other fields are widely used. In most applications, the liquid ring vacuum pump to work as a working fluid, people used to call it a water ring vacuum pump. Working principle Figure 2-75 shows the working principle of a single acting liquid ring vacuum pump. The impeller is eccentrically mounted in a nearly circular pump body. When the impeller is operated at a certain speed, due to the centrifugal force, the liquid in the pump body is circulated in the circumferential direction Thrown open to form a liquid ring close to the inner wall of the pump, forming a crescent space between the inner surface of the liquid ring and the impeller hub. When the impeller turns from point A to point B, the "air chamber" surrounded by the two blades, the hub and the inner surface of the liquid ring gradually increases, and the gas is drawn in from the drawn system. When it moves from point C to point A, the volume of the corresponding "air chamber" decreases from large to small, and the gas originally sucked in is compressed. When the pressure reaches the external pressure, the gas is discharged. Liquid ring vacuum pump in the course of work, the suction port is connected to the pumping system, the system for gas suction to form a vacuum. The discharge side also discharges the working fluid during the discharge process. To continuously provide the working fluid to the vacuum pump. A single-acting liquid ring vacuum pump, the impeller rotates a week, to complete a suction and exhaust process. Figure 2-76 shows the working principle of the double-acting liquid ring vacuum pump. The impeller is installed in the oval pump body. When the impeller rotates, two crescent-shaped spaces are formed between the liquid ring and the impeller hub. During pump operation, Crescent-shaped space to complete a suction, exhaust process. Each rotation of the impeller to complete two suction, exhaust process.
