Common faults and solutions of sorting machine
Common fault one: Leakage of solenoid valve
Reason for malfunction: There is dust inside the valve; The solenoid valve is damaged
Solution: Repeat valve testing; Replace the solenoid valve
Common fault 2: The solenoid valve does not operate
Fault cause: Poor contact between the plug and socket behind the valve; Valve core breakage; Color selection board damaged
Solution: Re plug and unplug, repair the poor contact area; Replace the solenoid valve; Replace the color selection board
Common fault three: Low jet volume of solenoid valve
Reason for malfunction: There is dust inside the solenoid valve; Low air pressure
Solution: Repeat high-frequency testing of the solenoid valve; Check the pressure gauge and related gas circuit
Common Fault 4: Material Splashing
Reason for malfunction: The temperature difference between the material and the hopper is too large; Dust clumping in the material trough; Scratches on the material trough
Solution: Adjust the temperature of the material tank to be roughly consistent with the temperature of the material; Clean the material trough with soft cloth material; Polish with fine sandpaper or replace the material groove
Common fault five: Frequent action of solenoid valve
Reason for malfunction: The color selection method was not selected correctly; Background board position not set properly
Solution: Choose the correct color selection mode; Readjust the background board
Common fault six: The whole machine is basically colorless
Reason for malfunction: low sensitivity; The power supply of the solenoid valve is not turned on
Solution: readjust sensitivity; Turn on the power supply of the solenoid valve
Common Fault 7: The quality of color selection is getting worse and worse
Reason for malfunction: There is dust on the glass of the sorting box; The color sorting machine is not cleaned thoroughly
Solution: Manually clean the dust or use a soft cloth to wipe off the dust on top; Check the dust cleaning device or replace the rubber strip
Common fault 8: Poor single-sided sorting effect of the whole machine
Reason for malfunction: Inappropriate cleaning and poor cleaning effect of rodless cylinder
Solution: Adjust the dust scraper and the dust scraping speed
Common Fault Nine: The sorting machine frequently shuts down
Reason for malfunction: high sensitivity; Improper adjustment of the background board; High impurity content in raw materials; Insufficient gas supply pressure of sorting machine; Frequent occurrence of air pressure protection
Solution: readjust sensitivity; Readjust the background board; Reduce production; Check the air pressure; If the gas passes too far, it should be readjusted; Clean or replace the filter element to ensure smooth pipeline flow
Common Fault 10: Air Compressor Failure
Fault cause: Damage to the three-phase winding of the motor; Damaged or poorly connected communication contactor; Damaged or poorly connected thermal relay; 380V power supply phase loss; Three phase voltage imbalance; The control switch circuit is damaged or abnormal
Solution: Replace the motor; Repair or replace the AC contactor; Repair or replace the thermal relay; Repair power supply lines; Adjust the transformer to balance the three-phase power supply; Check the control switch and circuit
