Essentials of vacuum pump operation
When the water ring pump is running, it must be constantly filled with water to maintain the liquid seal inside the pump, and also play a cooling role, but the degree of vacuum that the pump can cause is limited by the temperature of the water in the pump body.
The liquid ring vacuum pump can prevent the extracted gas from directly contacting the pump casing. Therefore, as long as the impeller is made of corrosion-resistant material when pumping corrosive gas, it is sufficient. The liquid injected into the pump must not react chemically with the gas. For example, water can be used when sucking air, and concentrated sulfuric acid can be used when sucking nitrogen. It should also be noted that the liquid used should not contain solid particles, otherwise, the impeller and the casing will often be worn and the suction capacity will be reduced.
A single-stage steam jet pump can only obtain 90% vacuum. If you want to obtain more than 95% vacuum, you can use several steam jet pumps in series to obtain a greater degree of vacuum.
