About fan alignment
Alignment and misalignment of the machine are generally considered to meet the installation requirements as alignment. But we can further expand: the vibration of the fan is the result of the comprehensive action of the space force system, and it can also be simplified to the "mass-spring system" vibration. The deformation generated by this vibration is within the elastic deformation range. We can all call it This is alignment, otherwise it is misalignment.
Judging whether the vibration deformation of the fan is within the elastic deformation range, compared with the "mass-spring system", it is much more complicated. The concentricity error and horizontality error of the coupling are too large, the anchor bolts and other fixing bolts are loose, the bearings are damaged, the cement foundation is not rigid enough, and the impeller material is fatigued. These may make the vibration of the fan (the whole) outside the elastic deformation range. On-site dynamic balancing is difficult to do, mainly in how to determine whether the fan is running within the elastic deformation range.
Knowing the force of the fan impeller, the Zhejiang jet fan can also determine whether the deformation of the fan vibration is running within the elastic deformation range, which makes the on-site dynamic balance relatively simple.
Tianjin Blower Group Co., Ltd. is a professional manufacturer of various fan designs and manufacturers. The company has senior engineering and technical personnel, advanced processing equipment, production technology and perfect detection methods and management systems, strong technical force and stable product quality. Passed ISO9001: 2008 international quality management system certification.
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 turning the pulley by hand, use a wooden or rubber hammer to lightly hit the end cover ribs. motion.
Emergency shutdown of the fan
During the trial run of the unit, the Anhui jet fan should immediately stop the jet fan in one of the following situations.
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;
