Double stage series Roots blower Pressure details:

The two-stage roots blower is composed of two HSR series standard roots blowers in series. When the gas enters the first stage fan for boosting, the gas temperature is reduced to below 40 ℃ through the intercooler, and then enters the second stage fan for further boosting. The maximum pressure rise of the unit can reach 177kPa. The host of the two-stage fan is driven by the same motor through belt drive or double shaft extension motor.

Introduction to working principle of two-stage series Roots blower:

Application scope and conveying medium two-stage roots blower is a device composed of two roots blowers in series. There are two three blade rotors with opposite directions inside each fan case. Each three blade rotor is supported by two bearings. A pair of high-precision synchronous spur gears are used to keep the relative positions of the two rotors constant. A certain clearance is maintained between the rotors and between the rotor and the case, and the rotor rotates without contact. Driven by the synchronous gear of the side box, the rotor separates the air inlet from the air outlet with the help of the "meshing" of the two rotors, completing the transfer process of the closed gas between the box and the rotor from the suction side to the discharge side. During rotation, the gas in the working chamber is pushed from the air inlet to the air outlet without internal compression. There are tiny gaps between rotors, between rotors and boxes, between rotors and wallboards, so there is no friction or contact wear in the working chamber.

Performance characteristics of two-stage series Roots blower:

1. The two-stage three leaf Roots blower has high volumetric efficiency, large air supply, stable operation, reliable use and relatively stable working characteristics.

6. Due to the adoption of the three blade rotor structure and the reasonable structure at the inlet and outlet of the housing, the fan has low vibration and noise. Pressure and temperature control to provide unit operation protection.
