It is a necessity of dust removal and purification. However, in the later period of operation, there will always be such problems. So how to effectively solve the problem when there are abnormal conditions? This article discusses the problems that usually occur in general.
1. The reason and solution of the air volume is too small
1. Reason: The system resistance is too large, and the fans are not selected properly.Solution: Re -evaluate the design of the system and re -select
2. Reason: System air duct leakage or debris blocking solution: blocking or cleaning
3. Reason: Leaf wheel steering error solution: correct steering: the position of the two -phase power cord of the motor at any switching motor
4. Reason: adjust the door to open the angle of small solution: adjust
5. Reason: Solution of increased gas density (too much solid impurities contained in gas or too low gas temperature, etc.) solution: Reasons to eliminate gas density
6. Reason: Triangle belt slip caused by the reduction of speed. Solution: Adjust the tension
7. Reason: Excessive gap between the impeller and the inlet or severe wear solution of the blade: repair, replace
2. Reasons and solutions for excessive air volume
Reasons: System resistance is too small, and inappropriate solution to the selection of fan: Increase system resistance (such as properly blocking into the air outlet, etc.) or reduce the fan speed
Third, the cause and solution of the motor overload, temperature rise abnormalities and solutions
1. Reason: Little system resistance, excessive air volume (centrifugal fan) solution: increase system resistance or reduce fan speed
2. Reason: Large system resistance, too much air volume (axial flow fan) solution: reduce system resistance
3. Reasons: Solution of increasing gas density (too much solid impurities contained in gas or lower gas temperature is lower than the rated operating temperature, etc.) solution: Eliminate the cause of increased gas density
4. Reason: adjust the door to open the angle of small solution: adjust
5. Reason: Triangular belt is too tight solution: adjust the tight force of the belt
6. Reason: Small solution of the motor power has been selected: replace the motor
7. Reason: Motor wiring error solution: Check the circuit
8. Reason: Poor insulation, motor failure solution: repair or replace
Fourth, the cause and solution of abnormal sound sounds
1. Reason: The bearing has cracks, scars or impurities mixing bearing solutions: replace the bearings
2. Reason: Insufficient lubricating oil (the bearing emitted with the sound of the sound with the rise of temperature) solution: refueling
3. Reasons: Bearing lock -up nut loose solution: re -lock
4. Reason: Solution of spindle wear: Change axis
5. Reason: Axial Robe Solution: Find the reason and correct
6. Reason: The solution of the impeller and the air inlet or case: repair and adjust
7. Reason: The solution of the bolt of the bolt of the impeller and the wheel or a shaft head: Tighten the bolt
8. Reason: Fan inhalation of foreign bodies solution: Clear
9. Reason: adjust the door to open the angle of small solution: adjust
10. Reason: Poor pipeline system and high wind speed solution: Reform the pipeline system
5. Causes and solutions for bearing abnormalities
1. Reason: Excessive lubricating oil, excessive oil filling (often accompanied by oil leakage) solution: remove excess parts
2. Reason: Insufficient lubricating oil or poor oil quality solution: replenish oil or replace new oil
3. Reasons: Improper selection of lubricating oils, and the model does not meet the requirements. Solution: Clean the bearings and change it with qualified oil
4. Reason: adjust the door to open the angle of small solution: adjust
5. Reasons: Excessive solution of bearing installation: Check and reinstall the bearings
6. Reason: Solution of bearing fault or fatigue wear: Check and replace the bearings
6. Causes and solutions for vibration
1. Reasons: The imbalance of the leaf wheels (rust, dust accumulation, dirt and other foreign objects such as sticking to the impeller) Solution: Clean the impeller
2. Reasons: serious solution of leaf wheel deformation or wear: replace the leaf wheel
3. Reasons: Poor basic design, or resonance solutions caused by insufficient basis and rigidity: check the basic status, properly replenish and strengthen the foot bolt loosening
4. Reason: Mechanical vibration solution caused by poor bearing installation or damage: reinstall the bearings or replace
5. Reason: Motor vibration solution caused by motor failure: repair or replace the motor
6. Reason: Solution of bending deformation or wear solution of the spindle: Change axis
7. Reasons: Unsuble solution to the installation of a shaft or wheel: Adjust and re -correct
8. Reason: External vibration (such as vibration of pipelines) transmits to the wind turbine solution: the connection between the fan and the pipeline adopts flexible soft pipe, and the shock absorber is installed
9. Reason: Improper selection, resulting in the work of the fan under the unstable working conditions (the wind turbine is asthma and is accompanied by the noise) solution: adjust the fan speed or the re -selection
