Water ring vacuum pump working principle (Figure)

Water ring vacuum pump working principle: As shown in Fig. 1, the impeller 3 is eccentrically installed in the pump body 2, so when the impeller 3 rotates, the water is subjected to the centrifugal force to form a rotating water ring 5 on the inner wall of the pump body. The upper inner surface and the tangent to the hub in the direction of the arrow rotation, in the first half turn, the inner surface of the water ring gradually separated from the hub, so the impeller blades and the water ring to form a closed space, with the impeller rotation, the space gradually In the second half turn, the inner surface of the water ring is gradually close to the hub Yu, the space between the blades is gradually reduced, the pressure of the space gas is increased, and when the pressure of the gas is higher than the pressure of the exhaust port, The gas between the blades is discharged, so that the impeller rotates once a week, and the space between the blades sucks and discharges once. Many of the spaces keep working and the pump sucks or pushes the gas continuously. The working principle of the vacuum pump is that during the work process, the heat generated by the work will heat the working water ring, and at the same time part of the water is discharged together with the gas. Therefore, during the working process, the pump must be continuously supplied with water to cool and replenish the pump Consumption of water to meet the pump's job requirements. When the pump exhaust gas is no longer used in the pump exhaust connected to the gas-water separator (can make a water tank instead), the waste water and the part of the water discharged into the gas-water separator, gas and water separation, gas Erased by the trachea, the water left by the return pipe to the pump to continue to use. With the extension of working hours, working water temperature will continue to rise when the water supply from the gas-water separator to provide a certain amount of cold water (tap water) to reduce the working water temperature to ensure ^ can achieve the required technology Requirements and performance indicators. When used as a compressor, the pump exhaust 11 is connected with a gas-water separator, the gas-water mixture is automatically separated after entering the gas-water separator, the gas is delivered to the required system by the exhaust pipe, the working water is released automatically through the switch, Compressed gas, the working water is very easy to heat, the water discharged from the pump outlet, the temperature will become higher, so at the bottom of the gas-water separator. To continue to supply cold water to replenish the hot water was released, when asked Cooling effect, so that the working water temperature is not too high, so as to ensure the performance of the compressor to achieve the vacuum pump working principle of technical indicators to meet the technical requirements.
