Malfunction and maintenance plan of suction high-pressure fan
Generate malfunction	reason	Troubleshooting
The suction high-pressure fan does not rotate	Not connected to power supply	plug in
	The motor is not working	Check the motor wiring
	The suction high-pressure fan head is damaged	Repair or replace the high-pressure suction fan
	There is a foreign object stuck in the high-pressure suction fan	Remove foreign objects
Increased noise	Bearing dry lubrication	Add bearing grease (such as butter)
	Bearing damage	Replace bearings
	Impeller wear	Replace the impeller
	Loose or detached sturdy components	Tighten the fasteners tightly
	There are foreign objects inside the high-pressure suction fan	Remove foreign objects
Increased vibration	Bearing damage	Replace bearings
	Unbalanced impeller	Remove foreign objects from the impeller or calibrate the dynamic and static balance
	Spindle deformation	Replace the spindle
	The working state enters the turbulent zone	Adjust work status to avoid turbulent areas
	The inlet and outlet filter screens are blocked	Clean the filter screen
Temperature rise	The inlet temperature is too high	Reduce the inlet temperature
	Bearing dry lubrication	Add bearing grease (such as butter)
	The efficiency of the suction high-pressure fan decreases	Remove dust from the blade path
	Change in work status	Adjust work status
	Increased ambient temperature	Increase environmental ventilation and heat dissipation
Reduced pressure	Speed decrease	Low power supply voltage or motor malfunction
	Increased resistance in the pipeline network	Reduce pipeline resistance
	Change in work status	Adjust work status
	Reverse direction of motor rotation	Reconnect the motor
Decreased traffic	The inlet and outlet air filters are clogged	Clean the filter screen
	Speed decrease	Low power supply voltage or motor malfunction
	Increased resistance in the pipeline network	Reduce pipeline resistance
	Increased work status	Adjust work status
	Reverse direction of motor rotation	Reconnect the motor
