Specific embodiment
With reference to the attached drawing in the utility model embodiment, the technical solution of the utility model is described further.
A kind of water-ring vacuum pump, including the pump housing 1, gas-liquid separation device 2, water tank 3, air filter 4, cooling device 5
With threeway 6, as shown in Figure 1, be provided with air inlet 11 and exhaust outlet 12 on the pump housing 1,
The air inlet 11 is connected with 6 one end of threeway, and the exhaust outlet 12 is connected by pipeline with gas-liquid separation device 2,
The gas-liquid separation device 2 is provided with exhaust outlet 21 and collector nozzle 22, and the collector nozzle 22 is connected with water tank 3, and the water tank 3 is logical
It crosses pipeline to connect with cooling device 5, described 6 one end of threeway is connected with air filter 4, and one end is connected with cooling device 5, another
End is connected with air inlet 11.
Operation principle, the entrance of the flow route of gas is air filter 4, and after filtration treatment, gas enters three
Logical 6 enter the pump housing 1 from air inlet 11, are then discharged by the pump housing 1 from exhaust outlet 12, gas-liquid separation device 2 is entered along pipeline.
At this point, the steam mixed in gas passes through the effect gas-liquid separation of gas-liquid separation device 2, water flow back into water tank via collector nozzle 22
In 3, and gas is then discharged from exhaust outlet 21.
The flow route initial point of water is water tank 3, and after the pump housing 1 starts, water is entered from water tank 3 in cooling device 5, to water
It cools down.The water of cooled cooling, which is entered via threeway 6 after air inlet 11, to be entered in the pump housing 1.A part of aqueous vapor
Gas can be followed to enter gas-liquid separation device 2 by exhaust outlet 12, become water again through 22 reflow tank 3 of collector nozzle through processing,
Complete recycling for water, using water wisely.
The impurity such as the large dust particle entered in the gas of the pump housing 1 by the filtration of air filter 4 are gone
