Why is the pressure relief valve installed at the discharge of every positive displacement type blower?
Positive displacement type blowers like roots and compressors like piston type, screw type. Etc are equipped with a relief valve at their discharges because the motor power is determined by the pressure developed. In case of any blockage in the pipelines that leads to motor burnout. Unlike in centrifugal fans where the power consumption is determined by the volume flow rate.
