Screw air compressor common troubleshooting guide Foreword: In order to promptly guide and solve the fault of the user unit, we compiled according to the working conditions encountered in daily work. The guide was made. The reasons listed in this guide are the possible causes of the failure, but not all. I hope that you will continue to provide us with new discoveries and methods during the use process, so that we can continuously improve the guide and make it an effective tool for us. Fault phenomenon: The unit exhaust temperature is high (more than 100. °C) 1 The coolant level of the unit is too low (should be seen from the oil sight glass, but not more than half) 2 oil cooler dirty 3 oil filter core blocked 4 Thermostatic valve failure (original bad) 5 oil cut solenoid valve failure 6 cooling fan failure 7 Exhaust ducts are not smooth or exhausted (high back pressure) 8 temperature sensor failure Fault phenomenon: the unit has high fuel consumption or large compressed oil 1 too much cooling dose 2 return pipe blockage 3 The installation of the return pipe (distance from the bottom of the oil separation core) does not meet the requirements 4 unit pressure is too low 5 oil separation core rupture 6 The unit has oil leakage 7 coolant deterioration or overdue use Fault phenomenon: low unit pressure 1 The actual gas consumption is greater than the unit gas volume 2 bleed valve failure (cannot be closed when loading) 3 intake valve failure hydraulic cylinder fault pressure setting is too low 4 load solenoid valve (ISV) fault pressure valve is stuck Fault phenomenon: large current of the unit 1 voltage is too low 2 loose wiring 3 unit pressure exceeds rated pressure 4 oil separation core blocked 5 contactor failure host failure motor failure Air Pump,Car Air Tire Inflator,Car Tire Air Pump,Smart Tire Inflator Shenzhen High Railway Technology Co., Ltd , https://www.hrw-tech.com
