How Roots blowers should be better controlled
Roots BlowerIn the process of using the blower pressure control is very important, then the control of those methods? Roots blower small make up take you to understand.
I. Replace the bearings and gears of the blower and readjust the impeller clearance (sometimes the impeller clearance is larger due to worn gear bearings).
Second, under the premise of the motor rated current allows, increase the speed of the fan, fan outlet caliber unchanged, increase the fan's air volume, will also increase the pressure of the fan.
Third, increase the motor power of the fan, in general the fan itself is not active bad (as long as the bearings and gears have a good lubrication), if you increase the speed of the fan to achieve an increase in air volume and pressure, are not enough current value of the motor, it is very easy to burn out the motor, so the power of the motor to increase, you can increase the speed of the blower, but also to improve the pressure of the fan.
Fourth, reduce (small) the outlet of the fan, but not in the outlet of the blower on the reduction (small) outlet, should be reduced in the outlet of the pipeline (less), but also improve the pressure of the fan, this also needs to be with the current value of the motor, can not be blindly increased or decreased.
