I. What is the difference between the vortex blower and the Roots blower?
Both the vortex blower and the Roots blower rely on mechanical rotation to drive the blades inside the pump body to rotate, and rely on centrifugal force The principle of action is to achieve the mechanical equipment for the purpose of compressing gas, but there are certain differences between them:
1. Different properties
Vortex fan It belongs to the turbo fan, while the Roots fan belongs to the positive displacement fan.
2. Different shapes
The vortex air pump has a relatively compact shape, the air inlet and outlet are at the lower part of the fan, the volume is small, and the aluminum alloy material is used, and the weight is light , high strength; Roots blower uses pulley to drive the pump cavity to work, the volume is relatively large, and the production material is generally cast iron, and the weight is relatively heavy.
3. Different parameters
Under the same power, the initial flow of the vortex air pump and the Roots blower is not much different, and the pressure is slightly lower. The pump cavity is larger, so the flow and pressure are slightly higher.
4. Different maintenance
The whirlpool fan basically does not need maintenance, just pay attention to the simple maintenance of the whirlpool air pump and the maintenance of the high pressure whirlpool fan bearing two Aspects can be; Roots fans need regular maintenance, such as adding lubricating oil, updating gear grease, etc.
5. Different prices
Under the same power, the price of the vortex air pump is relatively cheap, while the Roots blower is more expensive.
Second, which is better between the vortex fan and the Roots blower
The efficiency comparison between the vortex blower and the Roots blower is not fixed, because different fields Different application requirements will also affect the efficiency of the fan. If you want to know which is better between the vortex fan and the Roots fan, we can compare:
The vortex fan sends the gas out by centrifugal force, and the Roots fan The fan is the forced delivery of gas, that is, compressed gas delivery. Taking sewage treatment as an example, the whirlpool fan is suitable for oxygen supply in small pools, which is economical and cost-effective; the Roots fan is used in large-scale sewage treatment, and the wind pressure is relatively large. According to the pressure and air volume you use, the Roots blower is more suitable if the wind pressure is large and the air volume is large. However, if the wind pressure is within 20KPa and the air volume is large, it is more suitable to use a vortex fan.
