Axial Fan-Jin Blower (Online Consultation) -Fujian Axial Fan:Tianjin fan , Tianjin blower , Tianjin fan
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 by resistance of pipe network, etc. At present, there are still selections through the Web 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, Jiangsu axial flow fans, 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 fan volume and full pressure, the Anhui axial flow fan can determine the fan model through the fan's dimensional performance table (each fan product manual has relevant data). And machine number, at this 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's application, process requirements, and application occasions to meet the required working conditions. The rated flow and rated pressure should be as close as possible to the flow and pressure required by the process, so that the operating condition point of the fan when it is running is close to the effective area of the fan characteristics.
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. Axial flow fans, carefully wash 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, Hunan axial flow fan, 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.
What is the role of centrifugal fans and axial fans in mechanical ventilation? Two different types of fans, centrifugal fans and axial fans, can play a role in ventilation in production and life, but because these two types are different, Their characteristics and functions are also different, but these two types of fans can be used in mechanical ventilation, and they can achieve the results that users want. However, there are still significant differences between the two types of fans. What are the different roles in machinery?
In some places, the use of centrifugal fans may cause condensation on doors and windows, walls, and even slight dew on the grain surface. As long as the fan is stopped, the window is opened, and the axial flow fan is turned on. If necessary, the grain surface is turned to remove the hot and humid air from the warehouse can. Condensation will not occur with slow-flow ventilation using an axial fan, and only the middle and upper layers of the grain temperature will rise slowly, and the grain temperature will decline steadily as the ventilation continues.
Although this phenomenon occurs, the effect of centrifugal fan cooling and precipitation is still very obvious, and only a short ventilation time can achieve good results. The disadvantage is that if the centrifugal fan is not well grasped, dew condensation may occur. Therefore, if the user uses the centrifugal fan, he must know in advance how to effectively prevent such a phenomenon.
Axial fans are different. Axial flow fans mainly use the function of slow ventilation to make the place achieve a good cooling effect. The advantage is that the unit energy consumption is relatively low. This is very important to society today. It is easier to add this type of fan. The possibility of being condensed is relatively low, so it is loved by consumers, but it also has its own shortcomings. For example, the precipitation effect of this fan is not very obvious, and the air volume is relatively small.
In any case, these two types of fans have their own advantages. Users should take their actual needs as the starting point in the selection process so that they can choose a more suitable fan.
