What should I do if the color sorter breaks down? The following ten common troubleshooting solutions may help you.
Common fault 1: Solenoid valve leaks
Cause of fault: Dust in the valve; Solenoid valve is damaged
Handling method: Repeated valve test; Replace the solenoid valve
Common fault 2: Solenoid valve does not work
Cause of fault: Poor contact between the plug and the socket behind the valve; Valve core is broken; Color sorting board is damaged
Handling method: Re-plug and repair the poor contact position; Replace the solenoid valve; Replace the color sorting board
Common fault 3: Small jet volume of the solenoid valve
Cause of fault: Dust in the solenoid valve; Low air pressure
Handling method: Repeated high-frequency test of the solenoid valve; Check Check the pressure gauge and related air circuits
Common fault 4: Material splashing
Cause of fault: The temperature difference between the material and the trough is too large; Dust in the trough is agglomerated; There are scratches on the trough
Handling method: Adjust the temperature of the trough to be roughly consistent with the material temperature; Clean the trough with soft cloth; Polish or replace the trough with fine sandpaper
Common fault 5: Frequent action of the solenoid valve
Cause of fault: The color selection method is not selected correctly; The background plate position is not set properly
Handling method: Correctly select the color selection mode; Re-adjust the background plate
Common fault 6: The whole machine basically does not select colors
Fault Cause: sensitivity is too low; solenoid valve power is not turned on
Solution: readjust sensitivity; turn on solenoid valve power
Common fault 7: color sorting quality is getting worse
Fault cause: dust on the sorting box glass; color sorter is not cleaned cleanly
Solution: manual cleaning or wipe the dust with a soft cloth; check the cleaning device or replace the rubber strip
Common fault 8: poor sorting effect on one side of the whole machine
Fault cause: rodless cylinder is not cleaned in place, poor cleaning effect
Solution: adjust the scraper and scraping speed
Common See Fault 9: Color sorter often stops
Fault cause: sensitivity is too high; background plate is improperly adjusted; raw material impurities are too high; color sorter air supply pressure is insufficient; air pressure protection often occurs
Handling method: readjust sensitivity; readjust background plate; reduce production; check air pressure; if the air path is too far, readjust; clean or replace filter element to make the pipeline unobstructed
Common fault 10: air compressor failure
Fault cause: motor three-phase winding is damaged; AC contactor is damaged or has poor contact; thermal relay is damaged or has poor contact; 380v power supply is missing phase; three-phase voltage is unbalanced; control switch circuit is damaged or abnormal
Handling method: replace motor; repair or replace AC contactor; repair or replace thermal relay; repair power supply line; adjust transformer to balance three-phase power supply; check control switch and circuit
