The wear of the axial flow fan will cause the fan to vibrate, shorten the life of the fan, and in severe cases, the fan will not work properly. In particular, the wear of the fan blades is particularly serious, which not only destroys the flow characteristics in the fan. Therefore, it is very necessary to study the wear mechanism of the fan and take corresponding anti-wear measures.
1. Dust wear on the fan
Large amounts of fine dust in fan operation can cause damage to fan bearings, blades and motors due to long-term accumulation. Due to the small particle size and the wide variety of dust, many dusts cannot be effectively eliminated, and damage is easily formed in the fragile parts of the fan. At the same time, in order to control the cost, some fan application units improve the ventilation effect of the fan and reduce the use of the fan dust collector, which will cause dust to damage the fan and increase the risk of fan wear and failure.
2. The operating conditions of the fan are unreasonable
Different locations and different function settings require different fans and different state adjustments to adapt, the difference between design and actual clearance, function and demand form the problem of fan selection, which can easily cause fan overload work and fan wear problems.
3. The fan is running too fast
Excessive speed is another important cause of fan wear. According to the data analysis of fan wear, the degree of wear is related to the operating speed of the fan. Under high temperature conditions, the fan speed doubles, and the fan wear increases three times.
Axial flow fans are very widely used, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans, air conditioner outdoor fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are usually used in applications with high flow requirements and low pressure requirements. Axial fans fix the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high.
It can be used for ventilation or heat dissipation in metallurgy, chemical industry, light industry, food, medical equipment, mechanical equipment and civil buildings. The pipes are installed in series at intervals to increase the wind pressure in the pipes.
