Water ring vacuum pump
Water ring vacuum pump
Liquid ring vacuum pump
The water ring vacuum pump is equipped with an eccentric rotor with fixed blades to throw water (liquid) to the stator wall. The water (liquid) forms a liquid ring concentric with the stator, and the liquid ring and the rotor blade together form a variable volume of the variable volume. Vacuum pump. The water ring vacuum pump is suitable for pumping out gas and water vapor, and the suction pressure can reach 33 mbar absolute pressure (97% vacuum). When using transformer oil as the working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar absolute pressure (99.3% vacuum), which can completely replace the reciprocating vacuum pump.
Water ring vacuum pump (referred to as water ring pump) is a kind of rough vacuum pump, which can obtain the ultimate vacuum of 2000~4000Pa, and the vacuum unit with vacuum pump can reach 1~600Pa. The water ring pump can also be used as a compressor, called a water ring compressor, which is a low pressure compressor with a pressure range of 1 to 2 x 105 Pa gauge. Due to the rapid development of vacuum application technology, water ring pumps have been paid attention to in the acquisition of rough vacuum. Since the gas compression in the water ring pump is isothermal, the flammable and explosive gas can be removed, and the dusty and water-containing gas can be removed. Therefore, the application of the water ring pump is increasing.
An appropriate amount of water is contained in the pump body as a working fluid. When the impeller rotates clockwise in the direction indicated 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 upper portion of the water ring is just tangent to the impeller hub, and the lower inner surface of the water ring is just in contact with the tip of the blade (actually the blade has a certain depth of insertion within the water ring). At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided by the impeller into a plurality of small cavities having the same number of blades. If the upper part of the impeller is 0°, the volume of the small cavity becomes smaller from 180° before the rotation, and it communicates with the suction port on the end face. At this time, the gas is sucked in, and when the inhalation is finished, the cavity is small. It 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.
In summary, the water ring pump relies on the change of the volume of the pump chamber to achieve the suction, compression and exhaust, so it belongs to the variable displacement vacuum pump.
The main advantage:
● Easy to install
● low noise
