Information

A look random file
Every fan of random file includes instructions, product certification, electrical wiring diagrams and the packing list, according to the packing list inventory, checking the quantity and quality when buying parts.


Second look at the grille and the fan if there are significant deformation
In the assembled fans cast net, a fan with a pen pointing to the highest point, slowly moving blades, a few other fan corresponds with the distance between the tip of the point should be very close, and then turn the blades, to observe rotation is light and flexible, and can be stopped at any position.


Third, look at the control mechanism is flexible
Control mechanism includes a speed control switch, timer knobs, toggle switch, light switch, etc. These control mechanism should be flexible operation, reliable contact. To speed block, two block at the same time are not allowed to turn on or does not go a block by the phenomenon. Press the stop button, each speed gear keys should be reset.


Four to see the activities of performance
Fan fan head stoop, Yang each angle flexible operation, locking securely, adjusted to the maximum depression or shake his head to the final position, grille shall collide with fan pillars. When the fan is running, stability is better, not dumping, shaking his head angle of not less than 60-80 degrees.


Five visits startup performance
Pros and cons of starting performance is an important indicator of quality fans. Inspection, should be adjusted in a slow gear, and start fan at 85% of rated voltage power supply, which uses 220 volts regulator will be reduced to 187 volts, electricity phoenix fan should start from a standstill, and the normal operation, A fan from the start to the normal operation of shorter the time required to start the fan motor, the better the performance.


Six see operation and speed performance
Energized to rotate back and forth several times after the toggle switch, check whether the failure or assembly too tight, in the process, fan mechanical transmission parts should not have abnormal noise. Fans in high, medium and low speed, the motor and blades should be smooth, low vibration, low noise. Fan shook his head, shut down should be agile, non-stop, arrest and jitter, the speed difference of each block should be obvious, air angle bigger the better. When the fan stops, the shaft axial clearance is not more than 0.5 cm, the gap is too big, it will cause axial movement and there is a crash during the operation.


Seven to see if the drain
After the fan is energized, if there is a strong hand to touch Ma inductance, with test pencil test, test pencil will light emitting display, can determine the shell leakage, can not choose.


Eight fans see continuous operation performance
After two hours of continuous operation fan, if the nose hot shell surface, indicating that the temperature is too high, you can not choose. Under normal circumstances, the nose housing surface temperature below 50 ℃, will not have a very hot feeling.
