Industrial cooling fans are axial and radial two, is based on the direction of the fan's work flow of air to be divided. When the axial fan works, the blades push the air to flow in the same direction as the shaft, so it is called axial fan. When the radial fan works, the blades push the air to flow in the direction perpendicular to the shaft, so it is called radial fan.
In general, the large-scale EC axial fan is mainly suitable for the exhaust of dust, gravel and other places; medium-sized EC axial fan is mainly suitable for indoor ventilation and heat removal, such as: granaries, etc .; small EC axial fan are mainly applicable Ventilation and ventilation with mechanical equipment, such as: electrical cabinets.
Because traditional turbofan wind pressure is not generated in the central part of the fan, but by fan blade rotation appears. So no matter how high the speed, there will be no wind under the axis. But in the fan axis is the core of fever is the main source of fever. This situation caused a natural defect of the traditional axial fan: by the motor barrier, the airflow can not reach the central part of the smooth, resulting in "blind spots." The existence of the blind spot leads to the high temperature of the core part of the radiator, affecting the overall heat dissipation effect. To solve this problem, a centrifugal radial fan was manufactured.
EC axial fan has the advantages of simple structure, stable and reliable, low noise, wide selection of functions and so on.It can be used for ventilating or strengthening ventilation in metallurgy, chemical industry, light industry, food, medicine and civil buildings, Shell removed, can also be used as a freezer, but also in the longer exhaust pipe installed in series at intervals in order to improve the wind pressure in the pipeline.
Daily life should be well maintained and stored: the use of the environment should always be kept clean and tidy, keep the fan surface clean, inlet and outlet should not have debris, regularly remove dust and other impurities in the fan and pipe. The fan can only be operated normally under the normal conditions of the fan. At the same time, it is necessary to ensure that the power supply facilities have sufficient capacity and voltage stability, and are forbidden to run in the missing phase. The power supply lines must be dedicated lines and should not be powered by temporary lines for a long time.
