If the rotary fan fails, Hubei jet fan, please check carefully to determine the cause of the fault, and then repair it. 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 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.
Roots fan installation problems
First, the problem of the installation platform
加装固定，置于室内的罗茨风机，我们建议根据实际情况安装，可安装在平台 上面也可以安装在地面上面。 Generally speaking, Jiangxi jet fans, roots fans should be installed on the platform above the ground, but it needs to be determined according to the actual situation . Some small models of roots fans do not need to be fixed, and some types of roots fans must be installed . The Roots fan installed and fixed in the room is recommended to be installed according to the actual situation. It can be installed on the platform or on the ground. 面，安置于平台上能有效的避免一些外界侵蚀。 For Roots fans placed outside, we recommend to install them on the platform , which can effectively avoid some external erosion.
Second, the switch problem during installation
If we have two branches, the altitude difference between the two places is large. Jet fans, the Roots fans between the two must not be used interchangeably . Roots fans of the same model cannot be used interchangeably for different altitudes. 时候，我们也需要根据海拔来确定罗茨风机的型号，确保能够正常使用。 When selecting a Roots fan , we also need to determine the Roots fan model based on the altitude to ensure normal use.
The power distribution of the smoke exhaust fan does not meet the specifications
1. The power supply and distribution of wind turbines cannot meet the load level requirements of high-rise civil buildings. Some power supply lines are not connected to the fire power supply, but to the floor lighting distribution box. Some designs use single-loop power distribution lines, and some designs do not have automatic power switching devices at the end. Sichuan jet fans can not reach one. 2. The special dual circuit required for the secondary power supply load, with provisions for automatic switching at the end.
2. The installation of open circuit distribution lines does not meet the requirements. Some anti-exhaust fan power distribution lines wear PVC plastic pipes, and some metal pipes are not coated with fireproof paint, which does not meet the fire performance requirements of pipes.
