Buy liquid ring vacuum pump

How to choose a suitable liquid ring vacuum pump when buying a liquid ring vacuum pump? What kind of vacuum pump can meet your industry requirements. Maybe your industry needs to be oil-free, clean and corrosion-resistant. In fact, the most important thing is to understand the advantages and disadvantages of various liquid ring vacuum pumps. Secondly, according to the requirements of the industry to buy the appropriate liquid ring vacuum pump. Now let’s have a comprehensive understanding of the liquid ring vacuum pump.

liquid ring vacuum pump advantages:

Compared with other types of mechanical vacuum pumps, liquid ring vacuum pumps have the following advantages:

1. The structure is simple, the manufacturing accuracy is not high, and it is easy to process.

2. Compact structure, high pump speed, generally can be directly connected with the motor, without deceleration device, so a small size structure can be used to obtain a large amount of exhaust, and occupy a small area.

3. Compressed gas is basically isothermal, i.e. the temperature change loss of the compressed gas path is very small.

4. There is no metal friction surface in the pump chamber, so there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal.

5.Inhalation uniformity, stable and reliable operation, simple operation and convenient maintenance.

liquid ring vacuum pump disadvantages:

1. Low efficiency, generally around 30%, better up to 50%.

2. The low vacuum is not only limited by the structure, but also by the saturated vapor pressure of the working fluid. Using water as working fluid, the limit pressure can only reach 20000a. Oil as working fluid, up to 130 Pa.

In a word, because the gas compression in the liquid ring vacuum pump is isothermal, the flammable and gas-water mixture can be removed. With this valve and friction surface, dust-laden gases, condensable gases and points can be removed. Despite its low efficiency, it is still widely used.

When we buy liquid ring vacuum pump, we determine several parameters, such as vacuum degree and pumping capacity, motor power, etc. Look at the scale of the manufacturers after-sales service, our EVP vacuum pump manufacturer is trustworthy!
