Electric fan purchase tips, big secret electric fan, new product recommendation

The current temperature is getting higher every day. I believe that it will not be long before we should be annoyed by how to be cooler. In addition to air conditioning in summer, the most frequent electrical appliances we use are electric fans. How to choose a fan with excellent quality is in front of us. Today, Xiaobian brings the relevant content of the electric fan purchase technique and the new recommendation of the electric fan. Let's take a look at it.

Fan fan selection tips

1. Look at the random files - the random files of each electric fan include the instruction manual, product certificate, electrical circuit diagram and packing list. When purchasing, check the quantity and quality of the parts according to the packing list.

2. Look at the net cover and the fan blade for obvious deformation. On the assembled electric fan net cover, use a pen to point to the highest point of a fan blade, slowly move the fan blade, and the other several fan blades correspond to the point. The distance between the nibs should be very close, then turn the fan blades, pay attention to see if the rotation is light and flexible, and can stop at any position.

3. See if the control mechanism is flexible – the control mechanism includes speed control switch, timing knob, moving head switch, lighting switch, etc. These control mechanisms should be flexible and reliable. For the speed control gear, it is not allowed to have two gears connected at the same time or one gear cannot be pressed. Press the stop button and each speed stop button should be reset normally.

4, look at the performance of some activities - fan fan head tilting, tilting angles flexible operation, locking firmly, adjust to the maximum depression angle or shake the head to the final position, the net cover must not touch the fan pillar. When the fan is running, the stability is good, it can't be dumped, and the angle of shaking should not be lower than 60-80 degrees.

5, look at the startup performance - the starting performance is an important quality indicator of the electric fan. During the test, it should be adjusted to the slow speed, and when the rated voltage of the power supply is 85%, the voltage regulator will reduce the voltage of 220 volts to 187 volts to start the electric fan. The electric fan should be able to start from a standstill and operate normally. The shorter the time required for an electric fan to start from normal operation to normal operation, the better the starting performance of the fan motor.

6. Look at the operation and speed regulation performance - after the power is turned on, the head switch will be rotated several times to check whether it is malfunctioning or the assembly is too tight. In this process, the mechanical transmission part of the fan should not have abnormal noise. When the electric fan is running at high, medium and low speeds, the motor and the fan blades should be stable, with low vibration and low noise. The fan should be shaken and stopped, and there should be no abrupt, stagnation and jitter. The difference of the speed of each gear should be obvious, and the larger the air supply angle, the better. When the electric fan stops, the axial clearance of the rotating shaft does not exceed 0.5 cm, and the clearance is too large, which causes axial turbulence and impact sound during operation.

7, see if there is leakage - after the electric fan is energized, if the hand touch has strong hemp inductance, test with the test pencil, the test pencil will also display light, can determine the leakage of the casing, not optional.

8. Look at the continuous running performance of the electric fan. After the electric fan runs continuously for 2 hours, if the surface of the machine head is hot, the temperature is too high and cannot be used. Under normal circumstances, the surface temperature of the head casing is below 50 °C, and it will not feel very hot.

The above is a small series of electric fan purchase tips and the introduction of electric fans new recommendations, summer is the peak of the purchase of electric fans, but this year's electric fan market has not let consumers worry, consumers want to put money Spend on the blade, if you only pay for the remote control, energy-saving and other gimmicks, you need to spend a few hundred dollars on the cost, which is really worthless. When purchasing an electric fan, consumers still need to change their mindset. Without a remote control, it does not mean that the quality of the electric fan is not good. Just follow the above 8 purchase suggestions. I believe that everyone will be able to choose the best quality product with the least amount of money. .
