Roots blower air pressure is not restricted by the fan speed, no matter how the wind speed changes can remain the same (please note "to" two words).While the air volume is proportional to the fan speed, namely Q = KN Q: said air N: for fan speed K: for coefficient.
Within a certain range of pressure the pressure changes over the system size, the pressure changes over system resistance, with adaptability;Forced the hard exhaust gas characteristics, namely, when pressure changes, the flow changes little.
According to the above features:
Solution: 1. Change the system need to pressure, simply change the outlet diameter size.The step-down greatly, small booster.
2. Install relief valve.
3. Adjust the clearance.
