Can the pressure head be increased by replacing the motor and belt? Please advise!
Increasing the fan speed can increase the total wind pressure of the fan.
Isn't the air volume and speed of the Roots blower directly proportional?
It is necessary to pay attention to the strength of the impeller and main shaft. Excessive torque will cause the impeller to deform and the main shaft concentricity to shift. It is best to calculate the parameters before and after the change, and know what area to operate in through the curve.
Isn't wind pressure related to speed?
Just look at the characteristic curve of the fan.
