electric fan
Classification of 1. electric fan
Can be divided into: Taiwan (turn page) fan, platform (turn page) fan, floor (turn page) fan, wall fan, ceiling fan, box fan, water cooling fan (air conditioning fan).
Structure of 2. electric fan
Blade, fan head, protective cover, support structure, control part.
Table fans, wall fans, table fans, and floor fans have many similarities in structure. They all have drive motors, blades, supporting structures and control parts. The difference is only in the form of bottom acne. Ceiling fans are composed of suspenders, blades, Drive motor and upper and lower covers, some with governor and timer. The turning page fan is different from other electric fans in addition to its different appearance. It is mainly equipped with a turning page plate. Through the low-speed operation of the turning page plate, a conical swirling airflow is generated, giving people the feeling of natural wind.
The cold air fan does not use a compressor but uses the principle of water evaporation and ice melting to absorb heat to reduce the air temperature and play a role of humidification.
Model and specification of 3. electric fan
Fan model represents, for example, FS5-40 FS represents floor fan 5 represents the fifth generation product of the manufacturer.
40 means 400mm or 16"
250mm=10 300mm=12” 3500mm=14” 400mm=16”
Generally according to national standards: 300mm air volume is 38 cubic meters per minute
The air volume of 350mm is 51 cubic meters per minute and the air volume of 400mm is 65 cubic meters per minute.
FT stands for table fan FS stands for floor fan
FW stands for wall fan FD stands for ceiling fan
FC stands for ceiling fan FTS stands for table (ground) fan
KYT stands for page turning table fan KYS stands for page turning floor fan
4. use and maintenance
Start the electric fan should use fast gear, because the fan starting current is 4 to 8 times larger than normal operation. The fast starting voltage is fully pressed on the main coil of the motor. At this time, the voltage is sufficient, the starting is fast, and the motor generates less heat. On the contrary, after the slow start voltage is reduced by the speed regulation coil, the voltage applied to the two gears of the motor coil is low, the time when the motor coil passes through the high current is prolonged, and the heat generation of the coil increases, which affects the life of the motor and even destroys the motor. Therefore, it is best to use the fast gear when starting, and then adjust the gear after the speed is normal. This will not only help protect the motor, but also save electricity. (The maximum operating distance of the remote control is about 5 meters.)
