The best solution to solve the fault of industrial pipeline blower.mini fan manufacturer

　　Industrial pipeline blowers are widely used in industrial production. Because they can be connected to pipelines for coordinated operation, they can complete some special tasks. However, industrial pipeline blowers sometimes fail, and the difficulty of troubleshooting is still relatively high. In this article we will take a look at the fault solutions of industrial duct blowers in the future.

　　The blower is a necessity for dust removal and purification. However, in the later operation, the blower will always have problems of one kind or another. When the blower is abnormal, what if the problem is effectively solved? This article discusses the common occurrence of the blower. The problem.

　　Air volume is too small

　　Cause and solution

　　1

　　Reason: The system resistance is too large and the blower is improperly selected

　　Solution: re-evaluate the design of the system, re-selection

　　2

　　Reason: system air duct is leaking or blocked by debris

　　Solution: plugging or cleaning

　　3

　　Reason: Impeller steering error

　　Solution: Correct the steering: Swap the position of the two-phase power lines of the motor arbitrarily

　　4

　　Reason: The opening angle of the adjusting door is too small

　　Solution: adjust

　　5

　　Reason: The density of the conveying gas increases (the gas contains too many solid impurities or the gas temperature is too low, etc.)

　　Solution: Eliminate the cause of the increase in gas density

　　6

　　Reason: The V-belt slips and causes the speed to decrease

　　Solution: adjust the belt tension

　　7

　　Reason: The gap between the impeller and the air inlet is too large or the blades are seriously worn

　　Solution: repair, replace

　　Excessive air volume

　　Cause and solution

　　1

　　Reason: The system resistance is too small and the blower is improperly selected

　　Solution: increase the system resistance (such as properly blocking the air inlet, etc.) or reduce the blower speed

　　Motor overload, abnormal temperature rise

　　Cause and solution

　　1

　　Reason: The system resistance is small and the air volume is too large (centrifugal blower)

　　Solution: increase system resistance or reduce blower speed

　　2

　　Reason: The system resistance is large and the air volume is too small (axial blower)

　　Solution: reduce system resistance

　　3

　　Reason: The density of the conveying gas increases (the gas contains too many solid impurities or the gas temperature is lower than the rated operating temperature, etc.)

　　Solution: Eliminate the cause of the increase in gas density

　　4

　　Reason: The opening angle of the adjusting door is too small

　　Solution: adjust

　　5

　　Reason: V-belt is too tight

　　Solution: adjust the belt tension

　　6

　　Reason: The motor power is too small

　　Solution: replace the motor

　　7

　　Reason: Motor wiring error

　　Solution: Check the circuit

　　8

　　Reason: poor insulation, motor failure

　　Solution: Repair or replace

　　abnormal sound

　　Cause and solution

　　1

　　Reason: The bearing has cracks, scars or impurities mixed into the bearing

　　Solution: replace the bearing

　　2

　　Reason: Insufficient lubricating oil (bearing whistling accompanied by temperature rise)

　　Solution: Come on

　　3

　　Reason: The bearing lock nut is loose

　　Solution: Re-lock

　　4

　　Reason: Spindle wear

　　Solution: change the shaft

　　5

　　Reason: Shaft play

　　Solution: Find the cause and fix it

　　6

　　Reason: The impeller rubs against the air inlet or the casing

　　Solution: Repair, Adjust

　　7

　　Reason: The bolts connecting the impeller and the hub or the shaft head are loose

　　Solution: Tighten the bolts

　　8

　　Reason: The blower sucks in foreign objects

　　Solution: Clear

　　9

　　Reason: The opening angle of the adjusting door is too small

　　Solution: adjust

　　10

　　Reason: poor piping system, excessive wind speed

　　Solution: Retrofit the piping system

　　Abnormal bearing

　　Cause and solution

　　1

　　Reason: too much lubricating oil, too much grease filling (often accompanied by oil leakage)

　　Solution: remove the excess part

　　2

　　Reason: Insufficient lubricating grease or poor oil quality

　　Solution: add grease or replace with new grease

　　3

　　Reason: improper selection of lubricating grease, model does not meet the requirements

　　Solution: Clean the bearing and replace with qualified grease

　　4

　　Reason: The opening angle of the adjusting door is too small

　　Solution: adjust

　　5

　　Reason: bearing installation is too tight

　　Solution: Check and reinstall the bearing

　　6

　　Reason: bearing failure or fatigue wear

　　Solution: Check and replace the bearing

　　Vibration

　　Cause and solution

　　1

　　Reason: The impeller is unbalanced (rust, dust, dirt and other foreign objects adhere to the impeller)

　　Solution: clean the impeller

　　2

　　Reason: impeller deformation or serious wear

　　Solution: replace the impeller

　　3

　　Reason: Poor foundation design, or resonance caused by insufficient strength and rigidity of the foundation

　　Solution: Check the foundation condition, repair and reinforce properly

　　The anchor bolts are loose and locked

　　4

　　Reason: mechanical vibration caused by poor bearing installation or damage

　　Solution: Reinstall the bearing or replace it

　　5

　　Reason: motor vibration caused by motor failure

　　Solution: Repair or replace the motor

　　6

　　Reason: Spindle bending deformation or wear

　　Solution: change the shaft

　　7

　　Reason: improper installation of coupling or pulley

　　Solution: adjust and recalibrate

　　8

　　Reason: External vibration (such as pipeline vibration, etc.) is transmitted to the blower

　　Solution: The connection between the blower and the pipeline adopts a flexible flexible pipe, and a shock absorber is installed.

　　9

　　Reason: improper selection, causing the blower to work under unstable conditions (the blower surges and is accompanied by intermittent noise)

　　Solution: adjust the blower speed or re-selection

　　In summary, the troubleshooting of industrial pipeline blowers requires patience and meticulousness. Because the types of faults of industrial pipeline blowers are more complex, the difficulty of troubleshooting has also increased accordingly. Therefore, we should compare and analyze the faults according to the overall performance of the industrial pipeline blower, so as to effectively solve the fault.
