2BV Water Ring Vacuum Pump Working Principle
Working Principle of 2BV Water Ring Vacuum Pump
The impeller of 2BV water ring vacuum pump is eccentrically installed in the pump body as shown in the figure. When the impeller rotates, water is injected into the pump at the start. Therefore, when the impeller rotates, a rotating water ring is formed on the inner wall of the pump body under the action of centrifugal force. The inner surface of the water ring is tangent to the hub and rotates along the arrow direction. During the first half of the rotation, the inner surface of the water ring vacuum pump gradually separates from the hub. Closed space is formed between impeller blades and water ring. As the impeller rotates, the space expands gradually, the space gas pressure decreases, and the gas is absorbed from the disk suction port. In the latter half-turn process, the inner surface of the water ring gradually approaches the hub, the space between the blades decreases gradually, and the space gas pressure increases. When the pressure between the blades is higher than that of the exhaust port, the gas between the blades is absorbed from the disk exhaust port. Expelled. In this way, whenever the impeller rotates one week, the space between the blades sucks and exhausts once, and many spaces work continuously. The 2BV water ring vacuum pump continuously sucks or presses gas.
2BV water ring vacuum pump, because of the heat generated by work in the working process, will heat the working water ring, while some water and gas are discharged together. Therefore, in the working process, the pump should be continuously supplied with water to cool and supplement the water consumed in the pump to meet the working requirements of the pump.
When the gas discharged by 2BV water-ring vacuum pump is no longer used, there is a gas-water separator connected to the exhaust port of 2BV water-ring vacuum pump. After the exhaust gas and part of the water discharged into the gas-water separator, the gas is separated from the exhaust pipe, and the remaining water is supplied to the pump through the return pipe for continued use. With the extension of working time, the temperature of working water will continue to rise. At this time, cold water should be supplied from the water supply pipe to reduce the temperature of working water, so that the pump can meet the required technical requirements and performance indicators.
When 2BV water-ring vacuum pump is used as a compressor, the outlet of the pump is connected with a gas-water separator. The gas-water mixture is automatically separated after entering the gas-water separator. The gas is transported to the required system by the exhaust pipe, and the working water passes through the separator and enters the 2BV water-ring vacuum pump. When compressed gas is used, the working water is very hot. The water is discharged from the exhaust port of the pump and the temperature will become higher. The cold water should be continuously supplied by the water supply pipe to supplement the discharged water and play a cooling role at the same time, so that the working water temperature will not be too high, so that the performance of the compressor can meet the requirements.
