Double-stage Roots blower is a device composed of two Roots blowers connected in series. There are two tri-blade rotors inside each fan box
with opposite directions. Each three-blade rotor is supported by two bearings
r,
Utilizing a pair of high-precision synchronous direct bearings The gear
r,
keeps the relative position of the two rotors constant
r,
and maintains a certain gap between the rotors and between the rotor and the box
r,
Contactless rotation. The rotor is driven by the synchronous gear of the side box
r,
With the help of the
meshing
r,
of the two rotors, the air inlet and the air outlet are separated from each other
br/>r,
Complete the transfer process of the sealed gas between the box and the rotor from the suction side to the discharge side. During the rotation process, the gas in the working chamber is pushed from the air inlet to the air outlet without internal compression. There are small gaps between the rotor and the rotor, the rotor and the box, and the rotor and the wall panel
r,
Therefore, there is no friction
r,
and no contact wear parts in the working chamber.
Scope of application
Widely used in pneumatic conveying systems in ceramics, building materials, papermaking, electrical industry, petroleum, chemical industry, textile, aquaculture, sewage treatment, food and other industries.
b
Transport medium
Used to transport air and various neutral gases. But it is not suitable for transporting flammable, explosive, toxic and highly corrosive gases.
b
Performance characteristics
Double-stage three-blade Roots blower has high volumetric efficiency
r,
Large air supply volume
r,
Smooth operation
r,
Reliable to use
r,
Has relatively stable working characteristics.
b
The impeller and shaft are of an integral structure and the impeller has no wear. The fan performance remains unchanged and can operate continuously for a long time.
b
Forced gas transmission, the flow rate changes little with pressure, the outlet pressure is determined by the back pressure, and the transported gas is not contaminated by oil.
b
The selection of bearings is relatively reasonable, and the service life of each bearing is even. Moreover, the fan oil seal is made of imported fluorine rubber material, which is resistant to high temperatures and wear, so the fan has a long service life and high reliability.
b
The fan has a large volume utilization rate, high volumetric efficiency, simple and compact structure, and flexible installation methods.
b
Easy to use and maintain.
b
Due to the adoption of a three-bladed rotor structure and a reasonable structure at the air inlet and outlet in the housing, the fan has small vibration and low noise. Pressure and temperature control provide unit operation protection.
b
The fan oil seal is made of imported fluorine rubber material, which is high temperature resistant, wear-resistant and has a long service life.
b
, complete models, can meet the needs of different users for different purposes.
b
High-end CNC center production and processing, perfect management system tracking and monitoring.
Professional logistics company wooden box packaging, three guarantees, one year service and lifetime maintenance.
Buyers are welcome to visit and inspect, and buy with confidence.
