Principle of double pole series Roots blower in Roots blowe

  Principle of double pole series Roots blower in Roots Blower , working principle:
  Two stage roots blower is a device composed of two roots blowers in series
There are two three blade rotors with opposite rotation in the fan box of each roots blower
Each three blade rotor is supported by two bearings and uses a pair of high-precision synchronous spur gears to keep the relative position of the two rotors unchanged
There is a certain gap between the rotors and between the rotor and the box without contact rotation

  The rotor is driven by the synchronous gear of the side box, with the help of the & ldquo; Engage & rdquo;, The air inlet and Chu air inlet are separated from each other to complete the transfer process of the closed gas between the box and the rotor from the suction side to the discharge side
In the process of rotation, the gas in the working chamber is pushed from the air inlet to the Chu air inlet without internal compression
There is a small gap between the rotor and the rotor, between the rotor and the box, and between the rotor and the wall panel, so there is no friction and contact wear in the working cavity

  Application scope: , It is widely used in pneumatic conveying systems in ceramics, building materials, papermaking, power industry, petroleum, chemical industry, textile, aquaculture, sewage treatment, food and other industries

  Conveying medium: , It is used to transport air and various neutral gases
However, it is not suitable for transporting flammable, explosive, toxic and strongly corrosive gases

  Performance features: 1
The two-stage three blade roots fan has high volumetric efficiency, large air supply, stable operation, reliable use and relatively stable working characteristics
2
The impeller and shaft are of integral structure, and the impeller is free of wear
The performance of the fan remains unchanged for a long time and can operate continuously for a long time
3
It is not polluted by the outlet pressure, and it is not affected by the back pressure of gas transmission, and the back pressure changes with the outlet pressure
4
The selection of bearings is reasonable, the service life of each bearing is uniform, and the fan oil seal is made of imported fluororubber material, which is resistant to high temperature and wear, so the fan has long service life and high reliability
5
The fan has large volume utilization rate, high volume efficiency, simple and compact structure, flexible installation mode and convenient use and maintenance
6
Due to the adoption of three blade rotor structure and reasonable structure at the air inlet and outlet in the shell, the fan has low vibration and low noise
Pressure and temperature control to provide unit operation protection
7
The fan oil seal is made of imported fluororubber material, which is high temperature resistant, wear-resistant and long service life
8
The models are complete, which can meet the needs of different users for different purposes
