D Type 98KPA Inlet Pressure Multistage Centrifugal Blower For Water Treatment
D type 98KPA inlet pressure Multistage Centrifugal Blower for water treatment
Principle of multi-stage centrifugal fan
Centrifugal blower, its principle is to rely on the impeller of the role of the gas to increase the gas pressure, the
motor drives the fan impeller rotates, gases between the impeller spins, and under the action of centrifugal
force throws the gas, gas flow rate increases, the gas kinetic energy is converted to static pressure in the flow
of energy, and then with the fluid pressure, can make static pressure can be converted to velocity, gas
discharge through the vent port.
Equipment organization chart
Performance improvement of multi-stage centrifugal fan
It can improve the lubrication condition of the bearing and prolong the service life of the bearing.
2,Linearity of rotor
The efficiency of the multi-stage centrifugal fan is increased by 3% to 5%, and the temperature rise of the
noise and fan is reduced by optimizing the design of the multi-stage centrifugal fan impeller linearitly from
the binary flow to the three-element flow.
The regulating mode of multi-stage centrifugal fan.
1,flux adjustable
The multi-stage centrifugal blower can adjust the flow rate (50%--100%) through the inlet butterfly valve,
and it can also adjust the flow by adjusting the speed of the variable frequency motor, and the range can be
up to 40%, which can effectively save energy.
2,pressure adjustable
The pressure of the multi-stage centrifugal blower can be adjusted by adjusting the speed of the motor.
