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 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, fix the pulley on the rotating shaft, and while rotating the pulley by hand, the axial flow fan gently taps the rib of the end cover with a wooden or rubber hammer to make the rotor shaft flexible. motion.
Fan selection is a very technical task, and there are many specific selection methods, such as: selection by dimensionless characteristic curve, selection by logarithmic coordinate curve, selection by dimensional characteristic curve or performance table, Selection of variants, selection of pipe network resistance, etc. At present, Anhui axial flow fans also have a selection system through the Web online selection system and the use of special selection software. The methods are numerous and complex, and some methods require certain expertise.
For general business personnel, it is sufficient to be familiar with and master the two methods of dimensioning table selection and fan selection software. These two methods are simple and easy to operate. When selecting a fan, first of all, according to the two basic parameters of the required air volume and full pressure of the fan, the model and number of the fan can be determined through the fan's dimensioned performance table (each fan product manual has relevant data). At that time, more than one product may meet the requirements; at this time, the type, model and structural material of the fan are selected in accordance with the fan application, process requirements, and application occasions to meet the required working conditions. Rated flow rate and pressure, as close as possible to the flow rate and pressure required by the process, Fujian axial flow fan, so that the operating conditions point when the fan is running is close to the effective area of the fan characteristics.
The jet fan impeller is directly installed on the motor shaft. After the air is extracted at high speed, the air pressure difference between the front and back of the body is caused to achieve the role of blast ventilation. Jet fans are mainly: tunnel jet fans, induced jet fans, unidirectional jet fans, two-way jet fans and so on. Jet fans are widely used in chemical, petroleum, mining, subway tunnels and other places. Usually, the top of the place requiring ventilation is continuously arranged at a certain interval to achieve the purpose of ventilation and exhaust in this place.
