1, see the accompanying the machine file

Each electric fan machine file including the use of manuals, product certification, electrical wiring diagram and packing list, check according to the packing list and the parts quantity and number when purchasing.

 

2, look at the screen and fan blades whether obvious deformation

In the assembled electric fan net cover, use a pen point to a fan's highest point, slowly moving blades, several other fan blades corresponding points and the distance of the nib is very similar, and then rotation of the fan blades, observe whether rotation of light and flexible, and can be stopped at any position.

 

3, the control mechanism whether flexible

The control mechanism comprises a control switch, a timing knob, shaking head switch, lighting switch, the control mechanism should be flexible operation, reliable contact. On the governing block, two block at the same time are not allowed on or a block according to not go phenomenon. Pressed the stop key, the speed gear key should be normal reduction.

 

4, see the activity component on the properties

The electric fan head pitch, the angle of elevation of flexible operation, reliable locking, adjusted to maximum angle or shaking to the final position, net enclosures shall not collide with fan pillar. Fan operation, better stability, cannot be dumped, head shaking angle should not be less than 60- 80 degrees.

 

5, look at the start performance

Starting performance of the electric fan is an important quality index.

During the inspection, should be adjusted in the slow block, and in the power rated voltage 85%, whereby the pressure regulator for 220 volt voltage below to 187 volts to start the electric fan, electric fan should be available from start to the static, and normal operation, an electric fan from the start to the normal operation and the shorter the time spent, fan motor starting performance is better.

 

6, see operation and speed control performance

After electricity, reciprocating rotation of shaking head switch many times, to check whether the failure or assembly too tight, in this one process, fan mechanical transmission part should not have abnormal noise. When electric fan operation at high, medium and low speed, motor and electric fan blades should be smooth, low vibration, low noise. The fan head shaking, stops should be agile, without intermittent, stagnation and chattering phenomenon, each block speed of different should be apparent, air supply angle the bigger the better. In the fan stops rotating, shaft axial gap of no more than 0.5 cm, the gap is too large, running can cause axial movement and impact sound.

 

7, see whether the leakage

After the electric fan energized, if the hand touch strong hemp inductance, test pencil test, the test pencil can also display, can determine the casing leakage, can not be used.

 

8, see electric fan running performance

Electric fan to run continuously for 2hours, if the head of shell surface is hot, the temperature is too high, can not use. Under normal circumstances, the surface of the shell temperature of below 50℃, not very hot.
