The main parts and working principle of water ring vacuum pumps and water supply regulation _

1. casing, pump shell including outer cylinder + water pump cover before and after.

2。 The rotor, the rotor is composed of hot charging impeller, shaft, pump shaft with a sheath.

3。 Distribution board: board before and after the distribution board installed in front of the pump body and the back cover.

4。 Valve plate parts: consists of block water board and flexible disc, installed in a distribution board of the vent, can automatically adjust the Angle of the exhaust. Shaft seal parts: using packing seal, for water supply in cooling way.

5。 Bearing, the drive end of the pump is equipped with a plate of cylindrical roller bearing, the free end is equipped with a plate of cylindrical roller bearing and two tapered roller bearing.

vacuum pump impeller eccentric in a nearly circular pump body, impeller rotates due to centrifugal force function, flow into the pump body of water along the whirl of water ring pump shell formation. Due to eccentric water ring surface and wheel contour form a crescent-shaped space. Blade from close points to the far wall, the wall between two adjacent blades surrounded by gradually increase, the volume of gas suction by the outside world. Contrary to the side, the corresponding volume from large to small, originally suction gas compression, when the stress reaches or slightly greater than the atmospheric pressure, gas comes out. With stable rotating impeller, suction, exhaust process continuously, so it can continuous pumping gas. This is the principle of water ring vacuum pump.

1, due to the vacuum pump water supply has a certain range, in order to obtain the best water supply, water conservation can adjust water supply valve press program.

2, after the water ring vacuum pump operation, open the water valve, and then observe inlet pressure vacuum gauge.

3, slowly down water supply valve opening, when the vacuum gauge pointer to fluctuations or fall, when the water supply is not enough, again slowly open the water valve, when the vacuum gauge pointer to stability, then the best water supply water supply.

note: insufficient water supply, water ring vacuum pump suction ability to drop, and work is not stable, are too much and causes the waste of water, water supply will increase the pump shaft power, and even burning motor. This request when water ring vacuum pump to check vacuum gauge whether work properly. In case of any unnecessary losses.
