The main parameters of Roots blower include motor power, air volume and pressure parameters, which are the main parameters of Roots blower. The rotational speed of Roots blower is closely related to the air volume. The higher the rotational speed is, the higher the air volume of the blower is. However, the higher the air volume is, the higher the rotational speed is not necessarily. This is also related to the model of the blower. Many friends tend to confuse some concepts about the air volume, rotational speed and pressure of Roots blower.
People in the industry who have some knowledge of the performance of Roots blower will know that the rotating speed of Roots blower will not interfere with the wind pressure of the blower, that is, no matter how the rotating speed changes, the wind pressure of the equipment can remain unchanged. The fan speed is proportional to the air volume, that is, the larger the air volume, the higher the fan speed. The pressure characteristics of Roots blower mainly include the following aspects: within a certain pressure range, the change of the system affects the pressure.
Roots blower forces the air flow by the closed gap between the impeller and the casing, while axial flow and centrifugation flow by the kinetic energy transferred to the air by the blade, so the flow of gas transported by roots blower will not decrease much due to the increase of pipe pressure, but the volume of air will be compressed due to the increase of pipe pressure, but the total flow is unchanged, and the volume change is small, This situation will not occur for several times. In axial flow and centrifugal flow, when the pressure in the pipe becomes larger, the flow will be significantly reduced, and the larger the pressure is, the smaller the flow will be. When the drum does not move, the flow will be zero.
1. Air volume and pressure
The air volume and pressure are the selection parameters of Roots blower, and there is no inevitable relationship between them. Different working conditions, how much air volume is required and how much pressure is overcome, both of which are based on the actual situation. Then, the fan is selected according to these two parameters.
2. Motor power and pressure
There is a certain relationship between motor power and pressure. The greater the pressure is, the greater the motor power is required. It is impossible to accurately select the type through motor power and pressure. The pressure is mainly used to determine the motor power. These two parameters are closely related.
3. Motor power and air volume
There is no inevitable connection between motor power and air volume. It should be noted here that the greater the motor power is, the greater the air volume of the fan is. The motor power is mainly to overcome the pressure. The influence parameter of air volume is mainly the speed of the motor. The higher the speed is, the greater the air volume is.
I believe that after reading the above, you should also understand the relationship between the power and air volume of Roots blower. I hope it will be helpful to you.
