With the rapid development of industrial science and technology, people have different views and choices on the ring blower and roots blower of supporting equipment. Today, I will simply share with you the difference between the ring blower and the roots blower. First of all, the operating principle between the two is roughly the same, relying on mechanical rotation to drive the blade rotation inside the pump body, relying on the principle of centrifugal force to achieve the purpose of compressed gas.

The differences between them mainly focus on the following aspects:

1.Product shape

Ring blower is relatively compact, inlet and outlet at the bottom of the blower, small volume, aluminum alloy material, light weight, high strength. Roots blower uses a pulley to drive the pump body to work, the volume is relatively large, and the production material is generally cast iron, the weight is heavy, the temperature resistance is relatively poor, and it will be oxidized when working at high temperature.

2.Parameters:

At the same power, the initial flow rate of the ring blower and roots blower is not much different, but the pressure is slightly lower. Roots blower because the pump body is larger, so the flow and pressure is slightly higher. In the sewage aeration industry, ring blowers are generally used more in small areas, and Roots blower are generally used if the water level is large or deep.

3. Maintenance: 

The high pressure blower basically does not need maintenance, as long as you pay attention to two aspects, simple maintenance of the whirlpool air pump, and high pressure whirlpool blower bearing maintenance, pressure and intake cleanliness, very easy to use. Regular maintenance of Roots blower, such as adding lubricating oil, updating gear grease, etc., is also very convenient.

4. Application：Roots blower is often used in aquaculture aeration, sewage treatment aeration, cement material transportation, etc., more suitable for high pressure and large flow of gas transportation and pressure system. Ring blowers are widely used in all kinds of mechanical equipment, industrial, chemical, electronic industries are involved, and all kinds of laboratory pressure experimental devices.

Finally, Roots blower and ring blowers have their own practical fields and advantages. Regarding the manufacturing material, Roots blowers are mostly cast iron, and ring blowers are mostly aluminum alloy. If the intake air has water vapor and the like, it is recommended to use an ring blower, if the required flow rate is large, the pressure is high, then you need to use roots blower. Therefore, at the time of purchase, we should look at it according to our own realization, and do not blindly listen to the sales staff.
