What is the water ring vacuum pump _

What is a water ring vacuum pumps, water ring vacuum pump classification

1, single stage was a water ring pump

single stage was a water ring pump, single stage means that only a impeller, single acting means that when the impeller rotates, perform a suction and exhaust. The limiting vacuum pump has higher, but the pump speed and low efficiency.

2, single stage double function of water ring pump

single stage double role water ring pump, single stage means that only one impeller, double-acting refers to when the impeller rotating once, twice suction and exhaust. Under the same pumping speed, the size and weight of the double function of water ring pump are much smaller than monoculture water ring pump. Because the studio in pump hub of bilateral symmetry distribution, so the effect on the rotor load is improved. This type of pump with high pumping speed and higher efficiency, lower but ultimate vacuum.

3, the two stage water ring pump

two stage water ring pump is mainly composed of single pump series. In essence, two single stage was a water ring pump impeller share a spindle. Its main characteristic is under high vacuum and stable working conditions with large pumping speed.

4, atmospheric water ring pump

atmospheric water ring pump in fact is a unit of air jet water ring series. And atmospheric pressure pump series water ring pump in front of the pump, in order to increase the ultimate vacuum and expand the scope of its use.

two, the advantages of water ring vacuum pump

1. Simple structure, manufacturing precision is not high, easy to processing. Easy to operate and easy to maintain.

2, compact structure, general directly connected to the motor, pump RPM is higher. With the structure of the small size, large displacement can be obtained.

3。 No metal friction surface in the pump cavity, no lubrication pump. Both fixed and rotating components components between the seal can be through the water seal directly.

4。 The compressed gas in the pump chamber temperature change is very small, it can be considered to be isothermal compression, so it can remove inflammable and explosive gas.

5。 Because there is no exhaust doors and friction surface, so it can remove dust, gas condensable gas and water mixture.

3, the disadvantages of water ring vacuum pump

1, the efficiency is low, usually at around 30%, the best is around 50%.

2。 Low vacuum. This is not only due to the structure limits, and more importantly, due to the vapor pressure of the working fluid.

usually, water ring vacuum pump has a wide range of advantages, for example, the isothermal compression and water seal, they can remove inflammable, explosive and corrosive gas, also can remove gas containing dust and moisture.
