If the rotary fan fails, please check it carefully and determine the cause of the fault before repairing it. For the axial fan in Anhui, the replacement parts should be purchased according to the original fan accessory model.
1.Dismantling methods of rotary fan host
a. Remove the belt cover and belt.
b. Loosen the fixing bolt of the end cover on the side of the fan cover.
c. Screw in the two threaded holes in the end cover and remove the end cover.
d. Remove the V-belt from the shaft.
e. Loosen the fixing bolt of the end cover on the side of the V-belt pulley and remove the end cover. Note: When disassembling the main unit, be careful not to hurt the parts, and the removed parts should be placed carefully.
2. Repair of the rotary fan host
After disassembling the main unit, use axial sand blower to grind the parts where the rotor, cylinder block, end cover, blades, rings and other parts are damaged or rusted with fine sandpaper or oil stone, and wash them carefully with cleaning oil (be careful not to hurt the parts) , And reassemble after drying. Initial burnout, mixed debris, moisture and other failures can be repaired by the above methods. When the bearings, oil seals, etc. are damaged, they need to be replaced. Be sure to replace the O-ring.
3.Assembling methods of rotary fan host
a. Place the end cap with the shaft hole on the assembly table.
b. Put the side of the pulley of the rotor shaft down on the end cover.
c. Install the spring pin into the rotor shaft.
d. Install the blade into the rotor slot.
e. Put on the cylinder block (note that the position of the air outlet is on the side of the rotor near the hole in the cylinder block).
f. Insert the branch ring.
g. Install the bearing.
h. Install the O-ring.
i. Install the other end cover and fix the bolt.
j. Turn the cylinder block over and take off the end cap on the side of the pulley.
k. Put the branch ring.
l Install the bearing and O-ring. m. Install oil seal on the end cap.
n. Install the end cover, place the positioning pins, and tighten all the bolts.
o, stand up the host, put the positioning pin on the other side cover, and tighten all bolts.
p. Pour a small amount of lubricating oil into the air inlet to fix the pulley on the rotating shaft. While turning the pulley by hand, lightly tap the end cover rib with a wooden or rubber hammer to allow the rotor shaft to move flexibly.
Emergency shutdown of the fan
During the trial run of the unit, if any of the following conditions occur, emergency shutdown immediately.
1. The operation of emergency stop is to press the stop button of the main motor, and then perform the after-treatment after the stop;
2. The centrifugal fan suddenly experienced strong vibration and has exceeded the trip value;
3. There are scratches or abnormal friction sounds inside the body;
4. Smoke appears in any bearing or seal, or the temperature of a certain bearing rises sharply to an alarm value;
5. When the oil pressure is lower than the alarm value and cannot be restored to normal;
6. The fuel tank level is low and there is a suction phenomenon;
7. The axis displacement value obviously increased continuously, when it reached the alarm value;
The role of centrifugal fan components The main components of centrifugal fans and their functions are as follows:
Impeller; Guizhou Axial Fan, which produces head, transfers energy.
Chassis: Collect the gas from the impeller to the exhaust port, and convert part of the kinetic energy of the air flow into pressure energy.
Inlet adjusting damper: The output of the adjusting machine isolates the equipment from the system. (Also called deflector, some use frequency conversion technology, hydraulic coupler adjusts output,)
Spindle: transfer torque
Bearing: Bearing the radial axial load of the rotor, limiting the radial axial movement position of the rotor.
Coupling: connect the motor, transfer the shaft power
Concentrator: In the case of small loss, the airflow fills the section of the impeller inlet uniformly.
Bearing box; device bearing, filled with lubricating fluid and cooling fluid.
