Vacuum pump inlet and outlet pressure
Thread Content
The vacuum pump used for pressure swing adsorption is used to reduce the pressure in the adsorption tower from atmospheric pressure to a vacuum level; the outlet pressure of such a vacuum pump is at a slight positive pressure. What impact does it have on the vacuum pump if the pressure in the adsorption tower is not at atmospheric pressure, for example, it is 0.1 MPa(g), and vacuuming starts from this pressure? What impact does it have on the vacuum pump if the backpressure at its outlet is not at atmospheric pressure, for example, it is 0.1 MPa(g)?
The inlet pressure of the vacuum pump is high, which means there is a large volume of gas and the evacuation time is long
In the initial stage, it is used for liquid ring compressors; in the second stage, it is used for vacuum compressors. The inhalation flow rate decreases, and the power consumption increases compared to standard conditions.
