Roots Blower How to equip the motor? How to choose the transmission mode and power? (Model Selection)
Roots blower generally adopts the motor drive mode, of course, there are two other drive modes: diesel engine drive or diesel electric drive. As the most commonly used motor drive mode, how to choose the power configuration of the motor? We have sorted out some contents on this issue. Please read carefully if necessary
For the first time, let's talk about three commonly used motors:
① Ordinary motor
Roots blower is generally used with ordinary motor, with voltage of 380v and power of 0.75-280kw.
② Variable frequency motor
In order to save energy and reduce consumption, for users with high frequency of air volume, frequency conversion motor can be used to flexibly adjust the air output of roots blower. Generally, power plants use more.
③ Explosion proof motor
For special environment without flammable and explosive gases, explosion-proof motors will be used, which are commonly used in the chemical industry.
What are the transmission modes of Roots blower? There are two main ways of transmission: belt transmission, which can flexibly adjust the speed of the host, and can change the pulley or gear size to change the speed of the host, thus changing the air volume. However, this adjustment needs professional and skilled personnel to debug. If there is no technical personnel around to adjust, please contact the Roots blower manufacturer, Return to factory for maintenance or adjustment.
Another transmission mode is: direct transmission, that is, it is connected to the coupling. Generally, the direct transmission mode is selected when the speed of the motor is synchronized with the speed of the host. Generally, the transmission mode is determined according to the working conditions after communication with the customer.
How to select the power parameters of Roots blower motor?
① Pressure parameters
One of the main parameters affecting the selection of floor fan motor is pressure. The pressure is proportional to the selection of motor power. The configuration of Roots fan motor depends on the pressure. There are also the following other parameters.
② Air volume parameters
The air volume parameters will also affect the selection of motor. Under the same power motor, if a larger air volume is required, then the speed will need to be higher relatively. Therefore, when configuring the motor, first consider the pressure parameters, and then consider the air volume parameters.
③ Other external factors
The above factors of pressure and air volume have been considered, as well as the brand of the motor and whether the motor is explosion-proof.
If the air volume and pressure of Roots blower are determined, the power of the motor can be determined through the selection table. If you want a brand of motor, you can negotiate with the manufacturer of Roots blower to configure it.
Summary: For Roots Blower The selection of motor power mainly depends on the air volume and air pressure. The air pressure has a lot of influence on the motor power of Roots blower. When the machine model is the same model and the speed is the same, the pressure of lifting the motor power and exhaust will increase. When the sewage aeration or aquaculture aeration is used, the motor rotation will be difficult, At this time, we can increase the power to increase the air displacement, so as to achieve the ideal aeration effect. The above is about how to equip Roots blower with motor? How to choose the transmission mode and power? (Model Selection), if you have any questions, please contact us: 0531-83663588.
