Roots blower, also known as Roots vacuum pump or fan. There are many types of Roots blowers, such as direct connected Roots blowers, negative pressure Roots blowers, two-stage series Roots blowers, and dense Roots blowers. When choosing a Roots blower, we often encounter various issues such as flow rate, speed, pressure, and other properties. Let's talk about how to choose?

Roots blower pressure refers to the pressure at the outlet of the Roots blower, which does not generate pressure itself. It refers to the ability of the blower to overcome pipeline pressure, depending on the outlet pipeline and atmospheric pressure. Note that when selecting Roots blowers, it is necessary to choose a blower within the pressure range. If the actual pressure exceeds the rated pressure, causing the blower to overpressure, it may lead to motor burnout. If the pressure is insufficient, the desired effect cannot be achieved. The pressure unit of Roots blower is generally kgf/cm2 or kpa.

The flow rate of a Roots blower is the volume of medium conveyed by the Roots blower in a fixed unit of time. When using a Roots blower, it is generally necessary to use it to serve production or life, achieve a certain purpose or effect, and the air volume is an important factor in the selection of Roots blowers. The air volume is determined by demand, and in some industries, the required air volume cannot be reduced. For example, if 200 cubic meters of sewage are oxygenated and aerated per hour, the value of oxygenation and aeration for 200 cubic meters of sewage is reflected in the flow rate of the Roots blower. This value needs to be converted into an appropriate fan flow rate, which is usually measured in m3/min or m3/h. However, a large or small air volume can affect the oxygenation effect of the aeration tank.

The speed of the Roots blower determines the flow rate of the blower when the casing volume is the same. The higher the speed, the greater the flow rate of the blower. The rotational speed also affects the service life of the fan, as the rotor and casing of a Roots blower will experience slight wear. For Roots blowers with the same parameters, those with higher rotational speeds will experience more wear than those with lower speeds, which will affect their service life. So, when selecting a Roots blower, it is necessary to determine the speed of the Roots blower to meet the operating requirements. The speed unit of Roots blower is rpm/min. There are many factors that affect the selection of Roots blowers, such as the condition of the conveying medium and the environment in which the blower is used. As the operating conditions change and increase, there are more challenges and problems encountered in the actual selection of Roots blowers, making it more difficult. Therefore, in actual selection, it is necessary to carefully consider the factors and precautions that affect the selection of Roots blowers. By selecting the correct and suitable model, Roots blowers can not only meet the needs, operate smoothly and well, but also save costs and achieve the effect of saving electricity resources, saving unnecessary capital waste and maintenance costs, and achieving better goals and effects.

Therefore, it is very important to choose the right Roots blower for oneself. If one of the pressure and flow rate is not suitable, it may cause high energy consumption or make the equipment unable to operate, or even cause malfunctions, and even burn the Roots blower. Therefore, how to choose a blower is still entrusted to professional personnel.
