Determine The GreenhouseElectric Film RollerFaults Can Be Gradually Investigated By Observing The Operating Status, Detecting Key Components, And Analyzing Abnormal Phenomena. The Specific Methods Are As Follows:
Judging From The Running Status
Unable To Start: If There Is No Response After Power On, First Check If The Power Is Connected And If The Voltage Is Normal, And Rule Out The Possibility Of A Leakage Protector Tripping Or A Broken Wire; If The Power Supply Is Normal, It May Be Due To Motor Burnout (accompanied By A Burnt Smell), Capacitor Damage, Or Control Switch Failure. The Motor Winding Needs To Be Disassembled For Inspection Or Replacement Parts Need To Be Replaced.
Stuck/abnormal Noise After Startup: Stuck Occurs During Operation, Which May Be Caused By Foreign Objects Wrapped Around The Film Shaft And Film, Lack Of Oil In The Gearbox, Or Gear Wear; If Accompanied By Metal Friction Sound, It Is Mostly Due To Bearing Damage Or Misalignment Of Transmission Components. It Is Necessary To Stop The Machine For Inspection, Clean Up Debris, Add Lubricating Oil Or Replace Worn Parts.
Abnormal Film Rolling Speed: The Speed Has Significantly Slowed Down, Which May Be Due To Motor Aging, Insufficient Voltage, Or Excessive Load (such As Film Adhesion Or Deformation Of The Film Rolling Shaft); If The Speed Fluctuates, It May Be Due To A Control Module Malfunction Or Poor Sensor Contact.
Judging By Functional Abnormalities
Travel Out Of Control: If The Film Rolls To The Limit Position But Still Does Not Stop, It Is Often Due To A Malfunctioning Travel Switch Or Loose Positioning Pin, And The Travel Parameters Need To Be Recalibrated Or The Switch Needs To Be Replaced; If The Length Of The Roll Film Fluctuates, It May Be A Fault With The Encoder, And The Circuit Connection Needs To Be Checked Or The Accessories Need To Be Replaced.
Abnormal Forward And Reverse Rotation: Can Only Operate In One Direction, Which May Be Due To Relay Damage Or Reversed Control Circuit Connection; If The Direction Cannot Be Switched, It May Be A Fault With The Reversing Switch, And The Circuit Needs To Be Tested Or The Switch Needs To Be Replaced.
Judging Based On Environment And Appearance
Moisture Induced Leakage: If There Is Condensation Or Water Accumulation On The Surface Of The Equipment, And The Leakage Protector Trips During Operation, It May Be Due To Motor Sealing Failure Or Water Ingress Into The Junction Box. It Needs To Be Dried And The Sealing Ring Replaced.
Corrosion/deformation Of Components: Rusting Of Metal Components May Cause Transmission Obstruction, And Bending Of The Film Rolling Shaft May Cause Film Deviation. Rust Removal, Lubrication, Correction, Or Replacement Of Components Are Required.
When Troubleshooting, The Power Supply Should Be Cut Off First To Avoid Live Operation; Regularly Record The Operating Parameters Of The Equipment, Which Makes It Easier To Detect Abnormalities Compared To Normal Conditions. If Necessary, Contact Professional Maintenance Personnel To Inspect Circuits And Mechanical Components.
