The noise during the operation of the anticorrosive fan gradually increases, which will not only affect the workers in the factory, but the exhaust fan will also affect the surrounding environment. It is a kind of environmental pollution, so it should be resolved in time. So what are the reasons and solutions for increasing fan noise? Let's take a look:
1. Check if the motor frequency is correct
Adjust the corresponding frequency operation.
2. Check if the motor wiring method is correct
Adjust the correct wiring method.
3. Check whether the bearing is damaged
The operating specifications for replacing the motor bearings are based on work standards.
4. Check whether the anti-corrosion fan sucks the foreign object and whether the air pipe is blocked.
Clean foreign objects and clean the air duct.
5. Detect the disturbance of air flow, the resonance caused by the impact, the resonance phenomenon of reflection
Add a muffler to the duct and isolate the noise or add a soundproof box to the fan
6. Check whether the anti-corrosion fan bearing is damaged
Replace the fan bearing. The replacement method is based on the fan bearing replacement work standard.
7. Check if the duct is noisy, if there is a co-vibration duct, if the wall is too thin
Add support to the duct or add acoustic insulation to the duct.
8. Check if the fan running direction is correct
Adjust the fan running direction.
9. Check if the fan belt is loose and making noise
Replace the belt and adjust the tightness of the belt.
Working principle of fire exhaust fan :
Smoke prevention facilities are generally linked with fire alarm systems. When the control center's control console (cabinet) is in an automatic state, after a fire alarm occurs, the mine fan will be linked to the smoke prevention system, and the mechanical pressurized air blower will automatically start. , Pressurize the air to the smoke-proof staircase, the front room of the fire-fighting elevator room, or the combined front room without natural smoke exhaust conditions to prevent the inflow of smoke; at the same time, the fire valve of the corresponding smoke-prevention zone is automatically opened to exhaust the smoke After the fan is automatically started, the dense smoke is discharged to the smoke exhaust pipe or shaft through the smoke exhaust port. When the temperature reaches 280 ° C, the smoke exhaust wind will automatically stop.
When it cannot be started automatically, it can also be started remotely in the fire control center, or directly start the positive pressure blower and exhaust fan at the fan room site.
Causes and treatment of common faults of fans
1.Excessive fan vibration
Reasons: the rotor is out of balance; the foundation is not solid; the valve is too small to cause flying; the bearing is damaged.
Treatment method: redo the dynamic and static balance correction after replacing or repairing the bad parts; tighten the anchor bolts; replace the bearing body; adjust the opening of the valve.
2.Insufficient air volume and wind pressure
Reasons: insufficient voltage, low speed of centrifugal fan; large pipeline loss; incorrect fan selection.
Treatment methods: adjust the voltage; modify the pipeline, plug the leakage, replace the seals; reselect the model.
3.The bearing temperature rises too high
Reasons: too much or too little grease; impurities in the lubricant; imbalance of the rotor; excessive bearing load; insufficient cooling water in the oil station.
Treatment methods: adjust the amount of engine oil and grease; clean the fuel tank, replace lubricants and filters, and change the oil; after replacing or repairing damaged parts, rebalance; check the water channel, Jilin fan, and adjust the water amount.
4. The motor is overloaded,
Reasons: low voltage; large air volume; large power loss; spindle reversal.
Handling method: Close the small air inlet properly to reduce air leakage in the pipeline. When starting, close the valve damper to correct the spindle rotation.
Cause: The fuel tank or seal is damaged.
Treatment method: repair or replace the seal
