Double stage series Roots blower It is a machine composed of two Roots blowers in series. Each fan is independently equipped with two three blade rotors with opposite turning directions. Each rotor is supported by two bearings. With the help of two high-precision synchronous spur gears, the relative positions of the two rotors are always maintained. The relative positions of the two rotors remain unchanged. A certain clearance is maintained between the rotors and between the rotor and the box, so that there is no contact rotation. 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. Features of two-stage series Roots blower:

1. The impeller and shaft are of integral structure, and the impeller is free of wear. The performance of the fan is permanent and can operate continuously for a long time.
2. The selection of bearings is reasonable, the service life of each bearing is even, and the fan oil seal is made of imported fluororubber material, which is high temperature resistant and wear-resistant, so the fan has a long service life and high reliability.
3. Introduction of technology, processing of key parts by imported machining center, high precision, long service life and high reliability of host parts.
4. For forced gas transmission, the flow changes little with the pressure, the outlet pressure is determined by the back pressure, and the transmission gas is not polluted by oil.
5. Due to 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.
6. Double stage series connection, efficient intermediate cooling, high pressure, low energy consumption, more stable and reliable operation.
Application of two-stage series Roots blower
Scope of application: widely used in pneumatic conveying systems in ceramics, building materials, paper making, electricity, petroleum, chemical, textile, aquaculture, sewage treatment, food and other industries.
Transmission medium: used to transport air and various neutral gases. However, it is not suitable for conveying flammable, explosive, toxic and highly corrosive gases.
Special precautions for use
Due to its special structure, special attention shall be paid to the two-stage series roots blower during use: the two-stage roots blower has high requirements for its internal clearance. In the process of overhaul and daily maintenance, if the clearance adjustment and inspection are not in place, it may lead to friction between the rotor and the wallboard. In serious cases, the fan rotor may lock or even the fan may be scrapped.
Therefore, it is necessary to purchase Roots Blower After that, it is necessary to formulate a strict work inspection plan and check the machine every day to ensure that the Roots blower can operate safely and stably.
