Roots fan will generally choose the motor drive mode, of course, there are two other drive mode: diesel engine drive or diesel-electric drive mode. So as the most frequently used motor drive, motor power configuration how to choose it, on this issue we have organized some content, if necessary, please read carefully!

The first time we talk about the three commonly used motors:

① Ordinary motor

Roots fan is generally used with ordinary motors, voltage 380v, power 0.75-280kw.

② Frequency conversion motor

In order to save energy and reduce consumption for the size of the air volume of higher frequency users, you can use frequency conversion motor to flexibly adjust the size of the air volume of the Roots fan. Generally more used in power plants.

③Explosion-proof motor

For special environments without flammable and explosive gases, will use explosion-proof motors, generally more common in the chemical industry.

Roots fan what transmission mode?

Transmission mode there are two main one is: belt transmission, can flexibly adjust the host's speed, can change the pulley or gear size to change the host's rotational speed, so as to change the air volume, but this adjustment needs to be a professional know-how of the personnel to debug, if you need to adjust the side and there is no technical personnel, please contact with the Roots fan manufacturers, return to the factory for maintenance or adjustment.Another transmission mode is: direct transmission, that is, and coupling connection, the motor speed and the host speed synchronization generally choose the direct transmission mode, generally with the customer after communication and ultimately according to the working conditions to decide which transmission mode to choose.

Roots fan motor power parameters how to choose?

① Pressure parameters

One of the main parameters affecting the selection of floor fan motor is the pressure, the size of the pressure is directly proportional to the size of the motor power selection, the configuration of the Roots fan motor, you need to look at the size of the pressure. Of course there are the following other parameters.

② air volume parameters

Air volume parameters will also affect the motor selection, in the same power motor, if you need a little larger air volume, then relatively speaking, the rotational speed needs to be higher, so the motor configuration, first consider the parameters of the pressure, and then go to consider the air volume parameters.

③Other external factors

The above pressure and air volume factors are taken into account, as well as the brand of the motor and whether the motor is an explosion-proof motor are taken into account factors.

If the Roots fan air volume and pressure are determined, you can equip yourself with a motor through the selection table, you can set the power of the motor, if you want a certain brand of motor, you can discuss with the Roots fan manufacturer to configure.

Summarize: the choice of the size of the Roots fan motor power is mainly to look at the wind volume and wind pressure of these two parameters, wind pressure on the Roots fan motor power size has more impact, when the machine model in the same model, at the same speed, enhance the power of the motor exhaust pressure will increase in sewage aeration or aquaculture on the use of oxygenation and aeration, the motor rotation will be more strenuous, at this time we can Increase the power to increase the exhaust volume, so as to achieve the desired aeration effect.
