Direct connected high-efficiency energy-saving water ring vacuum pump

Direct connected high-efficiency energy-saving water ring vacuum pump，The Gongbo SK series water ring vacuum pump is used to suction or compress air and other non corrosive, water-insoluble, and solid particle free gases, in order to create a vacuum and pressure in a closed container. The inhaled gas is allowed to mix with a small amount of liquid. Widely used in the fields of machinery, petrochemicals, pharmaceuticals, food, sugar industry, and electronics.

Direct connected high-efficiency energy-saving water ring vacuum pump， As shown in Figure (1), the SK type water ring vacuum pump has impeller 3 eccentrically installed inside pump body 2. Therefore, when impeller 3 rotates, water is subjected to centrifugal force and forms a rotating water ring 5 on the inner wall of the pump body. The upper inner surface of the water ring is tangent to the hub and rotates in the direction of the arrow. In the first half of the rotation, the inner surface of the water ring SK type water ring vacuum pump gradually separates from the hub, forming a closed space between the impeller blades and the water ring. As the impeller rotates, the space gradually expands, the gas pressure in the space decreases, and gas is introduced into the space; During the second half of the rotation, the inner surface of the SK type water ring vacuum pump gradually approaches the hub, and the space between the blades gradually shrinks. The gas pressure in the space increases, and when it is higher than the exhaust port, the gas between the blades is discharged. In this way, every time the impeller rotates, the space between the blades is sucked and discharged once, and many spaces work continuously. The pump continuously sucks or compresses gas.

The SK type water ring vacuum pump generates heat during operation, which causes the working water ring to generate heat. At the same time, some water and gas are discharged together. Therefore, during operation, it is necessary to continuously supply water to the pump to cool and replenish the water consumed inside the pump, in order to meet the working requirements of the pump.

When the gas discharged from the SK type water ring vacuum pump is no longer used, a gas water separator (which can be replaced by a self-made water tank) is connected to the exhaust end of the pump. After the wastewater and some of the carried water are discharged into the gas water separator, the gas is separated and the gas is discharged through the exhaust pipe. The remaining water is supplied to the pump through the return pipe for continued use. With the extension of working hours, the temperature of the working water will continue to rise. At this time, a certain amount of cold water (tap water) needs to be supplied from the water supply of the gas water separator to reduce the temperature of the working water and ensure that the SK type water ring vacuum pump can meet the required technical requirements and indicators.
