Water ring vacuum pump pipe installation correct method

In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture return and vacuum degassing, water ring vacuum pump has been widely used. Due to the rapid development of vacuum application technology, water ring vacuum pump has been paid attention to in the field of crude vacuum acquisition. Because the gas compression in the water ring vacuum pump is isothermal, flammable and explosive gases can be pumped out, and gases containing dust and water can also be pumped out, so the application of water ring pumps is increasing. So what are the correct ways to install the water ring vacuum pump pipeline? This article takes you to understand.

1, Choose a reasonable pipeline scheme

① The shorter the distance between the vacuum system outlet and the vacuum pump inlet, the better;

② The less the pipe bends, the better;

       ③ The inlet pipe should be higher than the inlet center line of the water ring vacuum pump, and the outlet pipe should avoid factors that cause greater resistance, such as climbing on the outlet pipe, right Angle bends, etc.

       ④The diameter of the inlet and outlet pipe should be consistent with the inlet and outlet diameter of the water ring vacuum pump. If the vacuum system is small, the diameter of the inlet and outlet pipe can be small, but not less than 70% of the inlet and outlet diameter of the vacuum pump, and the outlet diameter should be greater than or equal to the inlet pipe diameter;

⑤ The turning point of the pipeline should be smooth transition;

Water ring vacuum pump inlet pipe to install a valve, used to adjust the amount of water into the water, the amount of water into the vacuum has an impact on the degree of vacuum, adjust the water by observing the vacuum meter pointer to control the valve, such as SK-0.8 limit vacuum can reach -0.087, in the working state, because the pipeline is not completely sealed state, The vacuum degree is about -0.06 to meet the work needs.

2. When installing or maintaining pipelines, prevent foreign bodies from falling into them.

3, The joint of the pipeline to add a gasket, there should be no air leakage, water leakage phenomenon.

4. A vacuum gauge is installed at the suction port of the water ring vacuum system in order to master the changes in the vacuum.

5, Water ring vacuum pump suction pipe installed valve, when the vacuum degree reaches the limit will produce a lot of noise, called cavitation sound, through the valve to adjust the vacuum degree, vacuum degree is high, pressure test burst detector, open the valve to release the right amount of gas, cavitation sound immediately disappear, vacuum degree decreases when the valve closed.

6, One of the important role of circulating water is to use cooling water ring vacuum pump working temperature, when the circulating water temperature exceeds 40 degrees, the vacuum will be reduced, timely supplement or replace cold water to reduce the temperature of circulating water, the vacuum pump on the fence equipment multi-purpose iron oil bucket to fill the circulating water, the water bucket is more.
