Air Foil Bearing Turbo Blower

The air foil bearing turbine blower adopts an excellent overall assembly design, and the main oil pump and the main shaft are connected by a coupling for easy replacement.

The design of the oil circuit system can prevent the lubricating oil from being contaminated by the surrounding environment and causing equipment shutdown. It has obvious characteristics such as small vibration, low noise and compact structure.

1. Running environment: All parameters can be displayed.

2. Easy to operate: using the touch screen, all relevant parameters are clear at a glance.

3. Fault display function: displays the cause of the fault and suggestions for action.

4. Historical data can be provided.

5. The gear box, pinion bearings, large gear bearings, large gear bearings and seals are all horizontally split. The seals, bearings and gears can be inspected by removing the upper cover of the gear box.

6. All major components, including gears, intercoolers, aerodynamic components, lubrication systems and control systems, are highly integrated and easy to conduct separate maintenance. Make troubleshooting and maintenance easy to operate.

The air foil bearing turbine blower is mainly composed of two parts: the rotor and the stator. The rotor includes an impeller and a shaft. There are blades on the impeller, as well as a balance plate and part of the shaft seal. The main body of the stator is the casing (cylinder), and the stator is also equipped with a diffuser, a bend, a return flow device, an air inlet pipe, an exhaust pipe and some shaft seals. The working principle of the centrifugal compressor is that when the impeller rotates at high speed, the gas rotates with it. Under the action of centrifugal force, the gas is thrown into the diffuser behind, and a vacuum zone is formed at the impeller. At this time, the fresh gas from the outside is Enter the impeller. The impeller rotates continuously, and the gas is continuously sucked in and thrown out, thereby maintaining a continuous flow of gas.

Air foil bearing turbine blowers rely on changes in kinetic energy to increase the pressure of the gas. When the rotor with blades (i.e., the working wheel) rotates, the blades drive the gas to rotate, transferring work to the gas, so that the gas obtains kinetic energy. After entering the stator part, due to the expansion effect of the stator, the speed energy pressure head is converted into the required pressure. The speed decreases and the pressure increases. At the same time, the guiding effect of the stator part is used to enter the next stage impeller to continue to increase the pressure, and is finally discharged from the volute. . For each compressor, in order to achieve the design required pressure, each compressor is equipped with a different number of stages and stages, and even consists of several cylinders.

Air Foil Bearing Turbine Blower Accessories Introduction

 

The impeller is the only component of the centrifugal compressor that performs work on the gas medium. Driven by the high-speed rotating impeller, the gas medium rotates with the impeller, thereby obtaining speed energy and partially converting it into pressure energy by the diffuser. It is thrown out from the impeller outlet under the action of centrifugal force, and enters the next stage impeller along the diffuser, curve, and return flow for further compression and boosting. Only when it is discharged from the compressor outlet is the gas medium transportation and boosting completed. Task. Impellers can be divided into three types according to their structural characteristics: open, semi-open and closed.

The function of the centrifugal fan deflector is to allow the fluid to enter the impeller axially. According to the query of relevant information, this is a question about the operation of circulating fluidized bed boilers. The answer to this question is axial entry into the impeller. A flow guide is installed before the centrifugal fan collector, often called an inlet baffle. The function of the flow guide is to adjust the load of the fan and change the rotation angle of the blades. This can adjust the load of the fan so that the fluid enters the impeller axially. .

 

The function of the volute is to collect the gas flowing out of the diffuser and discharge it to the condenser or interstage cooler. The shape of the volute on the radial surface is like a snail shell. The outer diameter and flow cross section gradually expand, which also plays a role in decelerating and expanding the airflow. The cross-sectional shape of the volute is often offset from a circle.

The diffuser is the most important fixed component. Its function is to convert the velocity energy of the high-speed gas at the impeller outlet into pressure energy. The diffuser usually consists of two parallel walls perpendicular to the impeller shaft. If there are no blades between the two parallel walls, it is called a vaneless diffuser; if there are blades, it is called a vane diffuser. The cross-section of the annular channel in the diffuser gradually expands. When the gas flows through, the deviation gradually decreases and the pressure gradually increases.

 

Because the air volume of the blower is small and the air pressure is high, it is suitable for efficient heat dissipation in small areas. For example, in boilers, ovens, etc., blowers are often the best choice. The blower also has the characteristics of simple structure and easy maintenance, making it widely used in small equipment.

The biggest advantage of the turbine is its strong blowing capacity. The blowing force is strong and the wind spreads far. However, the disadvantage of the turbine fan is that because the rotation speed is too high, it sucks in more air than other types of fans, so no additional components will be installed to prevent the incoming air. The air outlet is blocked and is mostly used in various fields that require high air pressure, such as industrial production and environmental protection.
