    How to mark the vacuum degree of water ring vacuum unit

    The vacuum degree value in water ring vacuum unit refers to the value that the actual pressure value in the negative pressure station is lower than the atmospheric pressure, which is usually marked by the following two methods:

    1. Mark with "absolute pressure" and "absolute vacuum degree": in the actual situation, the absolute pressure value of water ring vacuum unit is between 0 and 101.325kpa, which needs to be measured by absolute pressure instrument. In the place of 20 ℃ and zero altitude, the initial value of the instrument used to measure the vacuum degree is 101.325kpa.

    2. Use "relative pressure" and "relative vacuum degree" to identify: "relative vacuum degree" refers to the difference between the pressure of the tested object and the atmospheric pressure of the measurement site. Use a common vacuum meter to measure. Under normal pressure, the initial value of the meter is 0. When measuring vacuum, its value is between 0 and - 101.325kpa.

    Water ring vacuum unit can not only save water source, but also reduce environmental pollution. It is flexible and convenient to install. It is widely used in occasions where vacuum source is frequently used and the required air volume is not too large.
