electric negative ventilation fan ac

ac electric motor air suction fan use of foreign advanced technology for the production of F class insulation fan special aluminum shell motor. With under phase overload protection, long service life, stable operation, low noise.

matters needing attention

1, the installation of a smooth: negative pressure fan installation should pay attention to the level of the fan position, adjust to the negative pressure fan and the ground plane stability. After the installation of the motor does not have a tilt phenomenon.

2, the installation of negative pressure fans should make the motor's adjusting bolt in a convenient position. To adjust the belt tension when it is convenient to use.

3, the installation of the negative pressure fan bracket, be sure to let support and ground plane to the level of a solid, if necessary, on the side of the negative pressure fan installation angle to be reinforced.

4, after the negative pressure fan installation, to be around the tightness of the inspection. If there is a gap, the sun can be used to seal the plate or glass.

Some question and solution:

1. supply voltage is too low, negative pressure fan start or run, produce abnormal sound and vibration.

Solution: the power supply voltage is controlled within the range of rated voltage. Can usually choose the voltage regulator or power voltage regulator to stabilize the voltage.

2. negative pressure fan wind blade impact wind casing (cover).

Solution: fan blade adjustment reasons: vacuum blower fan motor bearing adverse, axial flow fan base screw loosening, wind leaf on the shaft is not fixed tightly, wind leaf apex and a hood body gap.

3. negative pressure fan base screw loose, impeller assembly is poor, the speed is too fast, fixed screw on the shaft and so on.

Solution: the negative pressure fan base, the shaft of the screw fastening. To re assemble and adjust the gap between the impeller and the impeller according to the technical requirement.
