The working principle of water ring vacuum pump _

water ring vacuum pump main part is the impeller and casing, impeller is made, the blade and hub blade radial plate type, and forward ( To the impeller direction of rotation) Bending type. Inside the shell form a cylinder space, impeller eccentric land in this space, at the same time the appropriate placement of the shell open intake and exhaust. Intake and outlet opened in shell on the gas distributor on the side of the impeller, suction and exhaust axial channel.

shell work for impeller provide a space not only, more important is a direct impact on water pump working medium ( Water) Movement, thus affecting pump in energy conversion process.

water ring vacuum pump before work, the need to inject a certain amount of water in the water pump, this part plays a transfer of energy and water sealing function. When the impeller rotation driven by electric motor, and the water in the blade driven by peripheral speed, due to the effect of centrifugal force, water outward movement, the water had a tendency to leave the impeller wheel flow to the inner surface of shell, which is in close to the casing in formation on the surface of a moving water ring. Due to the impeller and casing is eccentric, eccentric inner surface with water ring impeller. The inner surface, the blade surface and hub surface water ring and shell of two side cover surface into many small chamber without feeling. Because water ring and eccentric impeller, so in the different position of the small chamber volume is not the same. The small chamber with the rotation of the impeller, its volume is constantly changing. If we can in the small chamber volume in the process of change from small to big, and inhalation of gases are interlinked, will constantly in gas. When the volume of the chamber by large variable hours, closed, such already suction gas will be compressed with space volume decreases. After the gas is compressed to a certain extent, make the space and vent, which can discharge has been compressed gas. The working principle of

filled with just the right amount of water as the working medium in the pump body. When the impeller rotates clockwise, impeller water to be thrown. Due to the centrifugal force, water according to the shape of the pump chamber is roughly equal to the thickness of the closed ring. The inner surface of the lower part of water ring with the impeller wheel tangent, water ring area on the surface just contact with the tip of the blade ( Leaf blade actually internal insertion depth. At this point, the impeller wheel and crescent space formed between water ring, and the space is divided into an equal number blade impeller of small cavity. If the bottom of the impeller of 0 °, the small cavity volume from 180 ° rotating in front of the smaller, and with the suction connected on the face. At this point, the suction gas, at the end of the suction, cavity is smaller. It from the suction mouth; When the impeller to rotate, small cavity are getting smaller and smaller, and compressed gas; When the cavity connected with the vent, the gas discharge pump.
