LV Water/Liquid Ring Vacuum Pump:
LV series vacuum pumps are usually used to pump gas and water vapor without solid particles, water-insoluble, non-corrosive gas, and the suction pressure can reach 33 mbar absolute pressure (97% vacuum). By changing the material, it can also be used to pump corrosive gases or to use corrosive liquids as working fluids. LV liquid/water ring pumps are widely used in many processes in industrial production. Due to the rapid development of vacuum application technology, the application of water ring pumps is increasing.
Applications:
Widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, stone, coal washing, mineral processing, fertilizer, textile, and other industries in the process of vacuum evaporation, concentration, impregnation, drying, packaging and other processes.
Working Principle:
An appropriate amount of water is contained in the pump body as a working fluid. When the impeller rotates clockwise in the figure, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The inner surface of the lower portion of the water ring is just tangent to the impeller hub, and the inner surface of the upper portion of the water ring is just in contact with the tip end of the blade (actually the blade has a certain depth of insertion in the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the inner interface of the water ring, and this space is divided by the impeller into a plurality of small cavities equal to the number of blades. If the lower part of the impeller is 0° as the starting point, then the volume of the small cavity becomes smaller from 180° before the rotation, and the air inlet is opened to the air inlet. At this time, the gas is sucked in, and when the suction is terminated, it is small. The cavity is isolated from the suction port. When the impeller continues to rotate, the small cavity becomes larger and smaller, so that the gas is compressed; when the small cavity communicates with the exhaust port, the gas is discharged outside the pump.
