Guidelines for Troubleshooting and Resolving Common Malfunctions of Roots Blowers
As an important equipment in the industrial field, Roots blower often causes headaches once it malfunctions. Today we will talk about common fault phenomena, cause analysis, and solutions to help you quickly resume production.
1. The fan cannot start or has difficulty starting
**Pain point * *: When you press the start button, the fan has no response or makes a buzzing sound but cannot start, which is the most worrying situation.
**Possible reasons * *:
-Insufficient power supply voltage or incorrect phase sequence
-Motor winding short circuit or open circuit
-The impeller and casing are stuck due to friction
-The belt is too tight, causing excessive starting resistance
**Solution * *:
1. Check if the power supply voltage is normal and if the phase sequence of the three-phase power supply is correct
2. Measure the resistance value of the motor winding with a multimeter
3. Manually turn the wheel to check if the impeller is stuck
4. Adjust the tightness of the belt to the appropriate state
2. Abnormal noise during fan operation
**Pain point * *: The sharp abnormal noise emitted by the fan during operation not only affects the working environment, but may also be a precursor to serious malfunctions.
**Common cause analysis * *:
-Bearing wear or lack of oil
-Poor gear meshing or wear
-Improper clearance between impeller and casing
-Resonance caused by loose anchor bolts
**Processing steps * *:
1. First, stop the machine and check the lubrication condition of the bearings
2. Check the gearbox oil level and gear wear condition
3. Measure whether the clearance between the impeller and the casing meets the standard
4. Tighten all connecting bolts and foundation bolts
Insufficient air volume or pressure drop
**Pain point * *: Even though the fan is running, it feels like the wind is not strong enough, which affects the overall efficiency of the system.
**Potential issues * *:
-The intake filter is clogged
-Belt slippage causes a decrease in rotational speed
-System leakage
-Excessive clearance due to impeller wear
**Solution * *:
1. Clean or replace the intake filter
2. Check the wear of the belt and adjust the tension
3. Use soapy water to check if there is any air leakage at the pipeline connection
4. Measure the clearance between the impeller and replace it if necessary
4 fan overheating
**Pain point * *: The fan that feels hot to the touch makes people worry that it may "strike" at any time, and high temperatures can accelerate component aging.
**Reason for overheating * *:
-Insufficient or deteriorated lubricating oil
-Excessive system resistance leads to overload
-Cooling system malfunction
-The ambient temperature is too high
**Response measures * *:
1. Check the oil level and replace the deteriorated lubricating oil
2. Check if the system resistance is normal
3. Clean the dust on the surface of the cooler
4. Improve the ventilation conditions of the computer room
Remember, regular maintenance is a way to prevent malfunctions. It is recommended to check the lubricating oil every 500 hours and the condition of the bearings and gears every 2000 hours. Don't force yourself when encountering complex problems. It is wise to contact professional maintenance personnel in a timely manner.
