The role of centrifugal fans
Centrifugal fan is a machine that relies on the input of mechanical energy to increase the pressure of gas and discharge gas. It is a driven fluid machine.
Centrifugal fans are widely used in ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and sending of grain; wind tunnel wind source and inflation and propulsion of hovercraft.
The working principle of a centrifugal fan is basically the same as that of a turbo compressor, but because the gas flow rate is low and the pressure does not change much, it is generally not necessary to consider the change of the specific volume of the gas, that is, the gas is treated as an incompressible fluid.
Centrifugal fans can be made into right-handed and left-handed versions. When viewed from the side of the motor, the impeller rotates clockwise, called a right-handed fan, and counterclockwise.
If the rotary fan fails, please check it carefully and determine the cause of the failure before repairing. The parts that need to be replaced are 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 fine sandpaper or whetstone to grind the parts where the rotor, cylinder block, end cover, blades, rings and other parts are damaged or rusted, and wash them carefully with cleaning oil (be careful not to hurt the parts). reassemble. Initial burnout, mixed debris, moisture and other faults, Hubei fans can be repaired by the above methods, bearings, oil seals and other damage 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, erect the host machine, the tunnel construction fan, put the positioning pin on the other end cover, and tighten all the 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.
Selection basis and method of high temperature fan
High-temperature fans are generally made of high-quality stainless steel, high-pressure centrifugal fans, and titanium plates. The use of different materials according to different temperatures can ensure stable and durable operation in production. 2. The drive shaft of the fan must be specially treated, otherwise it will be deformed easily during high temperature operation, which will cause the fan to be paralyzed. 3. The fan's transmission box must be insulated from the fan casing and at the same time the bearing box Internal water cooling system and air cooling system are used at the top. 4. The fan's belt must choose high-temperature resistant high-quality belt. 5. The fan casing, air inlet, and external areas in contact with the gas are all treated with heat insulation. The above points are the accumulation of many years of experience in fan technology for Shandong Lanneng Environmental Protection Technology Co., Ltd., and I hope to share with you in the future.
