Selection method of electric fan
1. Look at the net cover and fan blades.
Whether the appearance of the electric fan is intact, check whether the net cover and fan blades are deformed. Point the pen at the high point of the fan blade and slowly move the fan blade. The corresponding points of other fans should be very close to the pen tip, and then check whether the blades rotate flexibly.
2. Look at the startup performance
Startup performance is an important indicator of the quality of electric fans. When purchasing, the electric fan should be set in the low gear, and the electric fan should be started when the rated voltage of the power supply is 85%, that is, when the voltage of 220 volts drops to 187 volts through the voltage regulator. Phoenix electric fan should be able to start from a static state while maintaining normal operation. The shorter the startup time, the better the startup performance of the fan.
The shorter the normal operation time of the electric fan, the better the starting performance of the fan motor.
3. Look at the operation and speed regulation performance
Turn the head switch back and forth several times after power-on, and check whether there is a fault or the assembly is too tight. In this process, there should be no abnormal noise in the mechanical transmission part of the fan. When the electric fan is running at high, medium and low speed, the motor and blades should be stable, with little vibration and low noise. The fan should shake its head and stop quickly, without intermittence, stagnation and jitter, and the speed difference of each gear should be obvious. The larger the air supply angle, the better. When the electric fan stops running, the axial clearance of the rotating shaft should not exceed 0.5cm. Excessive clearance will cause axial movement and impact sound during operation.
4. Look at the activity performance.
The activity performance of the electric fan mainly includes the flexible operation and firm locking of the fan head at all angles. At the same time, when adjusting the electric fan to a large depression angle or shaking its head to the final position, the net cover will not collide with the fan pillar. The angle of shaking your head should not be less than 60-80 degrees.
5. See if the control mechanism is flexible.
The control mechanism of electric fan mainly includes rocking switch, timing knob, speed regulating switch and lighting switch. Check one by one when buying to see if these control mechanisms are flexible.
How about Aux electric fan? And the way to buy electric fans, we have given you a brief introduction. Electric fans are small household appliances that we can't live without in summer, so we must pay attention to the safety of electric fans when buying them. We can buy it through some precautions in the prescription introduced above, and we must not buy inferior fans.
