Does the pressure of Roots fan have a maximum value?

In order to ensure that the elastic element of the pressure gauge can work reliably within the safe range of elastic deformation, the selection of the measuring range of the pressure gauge should not only be based on the size of the measured pressure, but also consider the speed of the measured pressure change, and the measuring range should leave enough room. When using a pressure gauge to measure stable pressure, the working pressure should not exceed 2/3 of the range.

When the conveying medium of Roots blower is corrosive gas, it is necessary to choose the instrument to measure the corrosive medium, and indicate the use environment and conditions to the manufacturer of Roots blower when ordering.

When selecting the pressure gauge, according to the pressure range and load condition of the Roots fan, the pressure is 1/3 to 2/3 of the full range of the pressure gauge, because the accuracy of this range is high, and it can be used under both stable and fluctuating loads, and the maximum range of use shall not exceed 3/4 of the full scale of the dial.

The pressure gauge of Roots fan is an instrument that measures and indicates the resistance of the pipe in the operation of Roots blower. It is used to measure the boost pressure in the operation of Roots fan. The pressure gauge of Roots fan is composed of a joint, a spring tube and a movement. Its working principle is that through the deformation of the spring tube, the movement drives the dial pointer, and the running pressure of Roots fan is displayed on the instrument panel, which is convenient for the operator to read and maintain the operation of the fan correctly.
