Design requirements and maintenance matters for Axial Fan

According to the principle that the kinetic energy is converted into potential energy, the axial fan can accelerate the gas by using the high speed rotating impeller, then slow down, change the direction of flow, and convert the kinetic energy into potential energy (pressure). In a single stage axial fan, the gas enters the impeller from the axial direction and changes into the radial direction when the gas flows through the impeller, then enters the diffuser. In order to better guarantee the quality of axial flow fan, the design of fan should be done well in the early stage, the specific design requirements are as follows.

Design requirements of Axial flow Fan

The working point to satisfy the required flow rate and pressure should be near the maximum efficiency point, the maximum efficiency value should be as large as possible, the efficiency curve should be flat, the stable working interval of the pressure curve should be wide, the structure of the fan should be simple, and the craft of the fan should be good. Convenient selection of materials and accessories, sufficient strength, stiffness, safety and reliability; stable operation, low noise; good adjustment performance, strong working adaptability; Fan size as small as possible, light weight, easy to operate and maintain, easy to disassemble and transport.

Matters needing attention in the maintenance of Axial Fan Gear

1. The use of high quality lubricating oil can prolong the service life of gears and bearings.

2. The use of gear treasure, significantly improve the finish of the tooth surface.

3. The edge of the pit is smooth, the handle is good, the pitting corrosion can be prevented, and the oil temperature of the reducer is 3 ~ 4 ℃.http://www.jnblower.com/
