High energy efficiency permanent magnet motor
The centrifugal turbine blower uses self-circulation cooling technology while rotating at high speed to ensure 95% high efficiency operation in the entire working range.
The simple structure design of the centrifugal turbine blower ensures reliability even under extreme working conditions. It provides high-speed induction motors and permanent magnet synchronous motors, and provides different types of motor options.
Simple and efficient cooling system, no external accessories required (air-cooled 1 water-cooled type); self-cooling system, cooling the motor and electrical components through inlet air.
All aluminum alloy casting volute
The volute cast from aluminum alloy is highly efficient and has a horizontal orientation on the suction side and a vertical or horizontal orientation on the outlet side. No rust to worry about, keeping the intake air clean.
Special air film bearings
Through aerodynamic design principles and accurate calculations, high-speed rotation is used to form an air film between the shaft and the bearing. The air bearing has no contact and friction, which greatly reduces energy consumption and is a 100% oil-free air lubricating oil system. The air pneumatic pressure formed between the shaft and the bearing has enough capacity to support the rotating parts (load capacity).
High precision impeller
The centrifugal turbine blower adopts a three-dimensional flow backward-curved design, with a wide operating range and variable efficiency up to 95%. The impeller is made of high-strength aluminum alloy impeller, which is light in weight and has a small moment of inertia.
In order to ensure the service life of the impeller, we conducted CAE finite element analysis during design, and the incoming materials passed
Flaw detection and 115% overspeed test after processing are completed to ensure safe operation during the life cycle.
Five-axis linkage CNC machining ensures the accuracy, reliability and durability of the designed impeller.
Changes in pressure and flow can be achieved by adjusting the rotation speed according to changes in external factors. We detect the fan's comprehensive parameters such as air volume, wind pressure, current, and vibration to predict the fan's surge, and prevent the occurrence of surge by increasing the speed or opening the vent valve, etc., with surge prediction and anti-surge capabilities Function.

Introduction to centrifugal turbine blower accessories
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.
