Cottle approach compressor failure Symptom: Unit temperature high temperature (over 100 ℃) unit oil level is too low (should endoscope can be seen from the oil air compressor repair, but not more than half) 1 Dirty oil cooler adding oil to the specified location clean cooler fins require the use of special cleaning agent deal with the oil filter clogging thermostatic valve replacement wick fault (bad elements) Clean or replace the original three fan motor failure to repair or replace the motor 4 off road exhaust is not smooth or climbs a large resistance (back) exhaust fan duct cleansing 5 ambient temperature exceeds the specified range of 38 ℃ or 46 ℃ lower ambient temperature does not increase the exhaust temperature sensor failure 6 replacement temperature sensor 7 wires coming loose wire overhaul compressor motor current is too high causes and solutions 1. Ambient temperature is too high. - Installation of air duct ventilation equipment type 2-phase voltage instability, due to phase voltage is too low (below 10%). - Please improve power system plant 3. Motor temperature controller failure. - Replace the temperature controller 4. overload failure. - Replace the starter overload 5. poor contact. - The starter contacts do maintenance 6. oil separator blocked. - When the pressure is greater than 0.8-1kg, replacing the oil separator core 7. No refueling motor bearings. - Motor bearings butter filling 8. motor bearing damage. - Replace the motor bearings 9. Motor poor insulation. - Remove motor insulation do to strengthen the work of handling motor 10. Loose wire. - Re-lock the motor wiring 11. blocking the air inlet. - Maintenance and cleaning the air inlet 12. The air filter is blocked. - Replace the air filter screw air compressor |??
