Fault phenomenon | Fault cause | Solution |
---|---|---|
Ejector leakage | Dust inside the ejector | Single test of the Particular |
Ejector has been damaged | Replace ejector | |
Ejector fails to operate. | Poor contact between the plug behind ejector and the socket | Re-plug, repair the poor contact position |
Disconnection occurred to the valve core | Replace the ejector | |
Colour Ejectorboard has been damaged | Replace colour ejector board | |
Ejector with small spray volume | Dust inside the ejector | Single high frequency test of the ejector |
Low air pressure | Check pressure gauge and relevant air circuit | |
Material flying | 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 colour separation | Low sensitivity | Readjust sensitivity |
haven't been power on | Power on the solenoid valve power supply | |
Poor Colour Separation Effect | Dust on the sorting glass | Remove dust manually or by soft cloth |
Incomplete for the colour sorter | Check or replace rubber strip | |
Poor Separation Effect of Complete Machine Side | Incomplete or poor ash removing for the rodless cylinder | Adjust ash wiper and the ash wiping speed |
Colour sorter stops working frequently | High sensitivity | Readjust the sensitivity |
Improper adjustment of background plate | Readjust the background plate | |
Raw material with high quantity of impurity | Reduce the yield | |
Colour 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 poor contact | Maintain or replace A.C. Contactor | |
Thermorelay damaged or poor contact | Maintain or replace thermorelay | |
380V power supply phase shortage | Maintain charging line | |
Three-phase voltage imbalance | Adjust transformer to achieve three-phase voltage balance |
