water ring vacuum pump working principle and operation

When the gas discharged from the vacuum pump is no longer used, a gas water separator connected to the exhaust end of the pump can be used as a water tank instead of itself. After the waste water and part of the water are discharged into the gas water separator, the gas and water are separated, the gas is wiped out by the wiping gas pipe, and the remaining water is supplied to the pump for further use through the return pipe.

The impeller is installed in the pump body 2 eccentrically. Therefore, when the impeller 3 rotates, the water forms a rotating water ring 5 on the inner wall of the pump body under the action of centrifugal force. The upper inner surface of the water ring is tangent to the hub and rotates in the direction of arrow. During the first half rotation, the inner surface of the water ring is gradually separated from the hub. Therefore, a closed space is formed between the impeller blades and the water ring. With the rotation of the impeller, The space is gradually expanded, and the space gas pressure is reduced. The air is sucked into the space: during the second half rotation, the inner surface of the water ring is gradually close to the hub Yu, the space between the blades is gradually reduced, and the space gas pressure is increased. When the air pressure is higher than the exhaust port pressure, the gas between the blades is discharged, so that every rotation of the impeller, the space between the blades is sucked and discharged once, and many spaces work ceaselessly, The pump continuously draws or presses the gas.

In the process of work, work will generate heat, which will make the working water ring hot, and at the same time some water and gas will be discharged together. Therefore, in the process of work, the pump must be continuously supplied with water to cool and supplement the water consumed in the pump, so as to meet the working requirements of the pump.

When the gas discharged from the pump is no longer used, a gas-water separator is connected at the exhaust end of the pump (a water tank can be made by yourself to replace it). After the waste water and part of the water are discharged into the gas-water separator, the gas is separated, the gas is wiped out by the wiping gas pipe, and the left water is supplied to the pump for further use through the return pipe. With the extension of working time, the temperature of working water will increase continuously. At this time, a certain amount of cold water (tap water) shall be supplied from the water supply of gas-water separator to reduce the temperature of working water and ensure that it can meet the required technical requirements and performance indicators.

When it is used as a compressor, the pump exhaust 11 is connected with a gas water separator, and the gas water mixture enters the gas water separator and then automatically separates. The gas is delivered to the required system through the exhaust pipe, and the working water is discharged through the automatic overflow switch. When the gas is compressed, the working water is very easy to heat up. The water is discharged from the pump outlet, and the temperature will become higher. Therefore, at the bottom of the gas water separator, cold water should be continuously supplied, In order to supplement the discharged hot water, it can play a cooling role when asked, so that the working water temperature is not too high, so as to ensure the performance of the compressor, meet the technical indicators and meet the process requirements.
