Inspection of rotary fan V-belt: after the rotary fan operates for a period of time, the V-belt will stretch. At this time, loosen the fixing bolts of the motor, move the motor, tighten the triangular plate to a proper position, and then tighten the fixing bolts of the motor. Note that the end faces of motor pulley and fan pulley are on the same plane. At the same time, check whether the top screws of the two pulleys are loose. If it is loose, tighten it and check whether the air filter is dirty every day. If it is dirty, remove the air filter, unscrew the butterfly nut, remove the cover and clean the filter.

Inspection for triangle belt of rotary fan:
After the rotary fan operates for a period of time, the V-belt will stretch. At this time, loosen the fixing bolts of the motor, move the motor, tighten the triangular plate to a proper position, and then tighten the fixing bolts of the motor. Note that the end faces of motor pulley and fan pulley are on the same plane. At the same time, check whether the top screws of the two pulleys are loose.

How to better operate, use and operate the rotary fan;
1. If you want to operate more efficiently in the later stage, remember to buy such equipment from regular manufacturers. Now there are some small workshops on the market. Although the price of three noes is relatively low, their performance and quality are not guaranteed by law
2. There may be differences in the installation method, equipment structure and basic parameters of each type of rotary fan. Therefore, everyone needs to carefully read the manual before operation to ensure that the staff master the usage of the equipment and operate correctly.
3. The startup sequence and shutdown sequence shall be operated according to the specified requirements, and the steps shall not be changed at will. There will be specific instructions in the manual to help you operate and use better.
4. In winter, due to the cold weather, many workers work close to the fan for heating, which is very wrong. You can't stay around this equipment for a long time, which is easy to cause skin damage.
5. Clean the rotary fan regularly, take corresponding maintenance and repair measures, timely find the faults or abnormalities of such equipment, and take measures to solve them to ensure that the equipment is in operation.
Causes and treatment of air pressure drop of rotary fan:
1. Due to frequent collision between two blades, the clearance between impellers increases; At this time, the position of the rotating fan gear should be adjusted to solve the lobe collision.
2. The fine impurities mixed in the gas rub the blade surface, resulting in blade wear. At this time, a dust collector or gas filter shall be installed in front of the air inlet of the rotary fan; If the blade is excessively worn, it is necessary to repair the blade or replace it with a new one
3. Sealing and casing leakage; At this time, the split surface of the seal and casing shall be repaired and filled.
4. Leakage or rupture of air outlet pipe; At this time, the pipeline shall be repaired or filled and fastened in places such as flanges
5. The rotating fan speed is insufficient; At this time, the rotating speed of the rotating fan shall be adjusted to meet the requirements. If the drive belt is loose, the drive belt needs to be adjusted or replaced.
