Fan Fault machine processing methods

Fan Fault machine approach:
Fault name
Cause
Remedy
Insufficient air flow
1, pipeline valve did not open.
2, the suction pipe is not large enough or fan intake vent is not changed interface is installed.
3, the belt slack.
4, the power supply voltage is low or reversed.
5, the suction pipe is too long, too much suction outlet, too small, multi-head is equipped with variable fan capacity is too small.
6, impeller excessive dirt accumulation.
7, fan snail lower stacking oil (water) too much.
8, duct connecting port leak.
1,
open valve 2, replace suction pipe and installation change the interface
3, adjust the pulley center distance, through tight belt
4, check the power or swap two phases are connected
5, replacement of wind turbines PolyU
6,
cleaning impeller 7, the oil (water) let go.
8, with glue or plastic glass sealed interface.
Fan vibration severe
1, impeller deformed or unbalanced.
2, bearing severe wear, impeller coaxial deviation is too large.
3, the foundation bolts or fan at a loose connection.
4, impeller wheel bolts or clamp bolts loose.
5, impeller backlog, excessive dirt sediments.
6, the rotation of the impeller housing backlog of air or grazing.
1, to replace the impeller.
2, replacement of bearings, adjust concentricity.
3, securing anchor bolts connecting bits.
4, clip fastening bolts or wheel bolts.
5, to clean impeller dust or debris.
6, adjust the impeller and the housing gap.
Motor temperature is too high
1, fan conveying gas density is too large, the pressure increases, the motor overload.
2, the input voltage is too high or too low or the motor phase operation.
3, the flow too much or too negative.
4, square cross section of the supply line is too small.
1, increase the motor power.
2, installed overload protection device.
3, to re-design and installation of air duct.
4. Replace the power supply line wire
Bearing temperature is too high or the oil spill
1, grease deterioration or lack of oil.
2, shaft and bearing misalignment, installation skewed.
3, serious bearing wear.
4, water cooling system is not smooth, or the amount of water is too small.
5, bearing tilt or refuel too much.
1, cleaning bearings replace oil.
2, improve concentricity adjustment bearing.
3, replace bearings.
4, clean delivery pipe or the amount of increase over the amount of water.
5, correction levels were observed hole.
6, clean transport through water pipes or increase.
And slip the belt beating
1, the belt is too long to relax.
2, two different pulley positions deflection straight line.
3, belt slip heat and noise.
1, adjust the distance to tension the belt pulley.
2, adjust the belt position so that the same line.
3, belt drag the bottom, replace the pulley.
