Advantages of Roots blower What are the advantages of Roots blower

Roots blower has the following advantages compared with other types of blowers:

There are gaps between Roots blower impellers, between impellers and casing and between wallboards. During operation, it is not necessary to inject oil for lubrication as screw compressors and sliding vane compressors do, so it can ensure that the gas transported is free of oil, and it does not need to use gas oil separators and other auxiliary equipment
The auxiliary equipment is also safe to transport gas containing dust or liquid droplets due to the existence of gaps and the absence of gas valves.
Roots blowers without internal compression process consume more compression work in theory than those with internal compression process. But there is no other mechanical friction except synchronous gear and bearing, so the mechanical efficiency is very high. Especially large roots blower
The product efficiency is very high, and the total adiabatic efficiency is also relatively high.
In addition, Roots blower has the advantages of simple structure, mature manufacturing process, convenient operation, long maintenance period, etc.

Installation drawing of Roots blower

Roots blower is a positive displacement blower, which is characterized by forced air supply. Under the appropriate rotating speed, the flow basically does not change with the pressure. Even in areas with low traffic, Roots Blower It will not surge like the centrifugal blower,
Roots blower has stable working characteristics.
Roots blower has no reciprocating mechanism, no exhaust valve, simple structure, few vulnerable parts, so it has a long service life, good oil balance, can run at a fast speed, and the rotor has good geometric symmetry, stable operation,
Large pumping speed can be obtained by increasing the rotating speed, so as to achieve compact structure, small volume and light weight.
Disadvantages of Roots blower What are the disadvantages of Roots blower
In the process of inward compression, the thermal insulation efficiency is low (especially for small models), but it is better for large models.

Due to the existence of clearance between impellers, it is easy to cause gas leakage, and the leakage flow increases with the increase of pressure rise or pressure ratio, which limits the development of roots blower towards high pressure;
Due to the impact of inlet and exhaust pulsation and backflow impact, the aerodynamic noise is large, so we can cooperate with Roots blower soundproof room.
  The above is the comparison between Roots Blower and other fans introduced by Xinqianshun Machinery. If you have any questions, please consult the customer service website or call us. We are looking forward to answering your questions.
