Troubleshooting |
| Ejector leakage |
Dust inside the ejector |
Cyclic test of the ejector |
| ejector has been damaged |
Replace ejector |
| Ejector fails to operate. |
Weak contact between the plug behind ejector and the socket |
Re-plug, repair the Weak contact position |
| Disconnection occurred to the valve core |
Replace the ejector |
| Color sort board has been damaged |
Replace color sort board |
| Ejector with small spray volume |
Dust inside the ejector |
Cyclic high frequency test of the ejector |
| Low air pressure |
Check pressure gauge and relevant air circuit |
| Material splashing |
Big difference in temperature between the material and the material chute |
Adjust temperature of the chute to approximate that of the material. |
| Dust agglomeration |
Clean the chute with soft cloth |
| Chute with scratch |
Sand papering or replace it |
| Frequent operation for solenoid valve |
Wrong ejector |
Correctly select sort mode |
| Position of background plate not properly set |
Readjust background plate |
| No color separation |
Low sensitivity |
Readjust sensitivity |
| haven’t been power on |
Power on the solenoid valve power supply |
| Weak Color Sorting Effect |
Dust on the sorting glass |
Remove dust manually or by soft cloth |
| Incomplete for the color sorter |
Check or replace rubber strip |
| Weak Separation Effect of Complete Machine Side |
Incomplete or Weak ash removing for the rodless cylinder |
Adjust ash wiper and the ash wiping speed |
| Color sorter often not work |
High sensitivity |
Readjust the sensitivity |
| Improper adjustment of background plate |
Readjust the background plate |
| Raw material with high quantity of impurity |
Reduce the yield |
| Color sorter is under pressure |
Check pressure; readjust if the gas circuit is too far away from the sorter |
| Frequent pressure protection |
Clean and open the pipeline by cleaning or replacing the filter element |
| Motor three-phase winding is damaged |
Replace the motor |
| A.C. contactor damaged or Weak contact |
Maintain or replace A.C. Contactor |
| Thermo relay damaged or Weak contact |
Maintain or replace thermo relay |
| 380V power supply phase shortage |
Maintain charging line |
| Three-phase voltage imbalance |
Adjust transformer to achieve three-phase voltage balance |
| Control switch circuit damaged or with problem |
Check the control switch and circuit |
