Fault detection method of combustion engine system

　　In the process of using the combustion machine, due to improper use, or mechanical wear and other external factors, often cause a variety of system failures.Today small make up for you to popularize the combustion engine ignition device system fault, engine flameout system fault, combustion engine does not operate system fault, below small make up take you to understand the combustion engine system fault what and how to deal with!NcXBoiler Burner

　　Failure of ignition device system under the premise of all normal, continuous operation of the combustion engine for 3 times, if the ignition device cannot be found, it should be judged as the fault of ignition device system, and corresponding routine inspection must be taken to detect the fault.NcXBoiler Burner

　　(1) ignition device system failureNcXBoiler Burner

　　Under the premise of all normal, continuous operation of the combustion engine for 3 times, if the ignition device cannot be found, it should be judged as the fault of the ignition device system, and corresponding routine inspection must be taken to detect the fault.NcXBoiler Burner

　　1. Check whether the working pressure of natural gas can be maintained at 3-5kpa normally. If it is too high or too low, it will indicate that the point does not ignite.NcXBoiler Burner

　　Solution: adjust the gas pressure regulating valve and adjust the working pressure.NcXBoiler Burner

　　2. Check the size of air inlet in a routine way. When the air inlet is a little larger, it is very easy to show the problem that the frequent ignition device cannot reach.NcXBoiler Burner

　　Solution: turn the intake down moderately, but not completely.NcXBoiler Burner

　　3, ignition device metal electrode or ignition transformer system fault ignition transformer does not ignite, or the ignition device metal electrode very dirty specific location error, will show the ignition device system fault.NcXBoiler Burner

　　Solution: test whether the ignition transformer can ignite the device, clean the metal electrode of the ignition device, adjust the spacing of the ignition device to maintain 2-3 mm.NcXBoiler Burner

　　4. Fault of gas valve set system when all normal ignition devices are installed, the valve set will be opened timely and the sound of opening can be heard. When it cannot be opened, fire will not be created.NcXBoiler Burner

　　Solution: routine check valve set coil, valve opening degree.NcXBoiler Burner

　　5, ignition controller system failure all ignition device applications from the intelligent controller, intelligent controller destroyed, unable to all normal ignition device.NcXBoiler Burner

　　Solution: replace the intelligent controller.NcXBoiler Burner

　　(2) failure of engine flame-out system when the combustion engine is running normally, it is suddenly put out, which means that the engine flame-out system fails.NcXBoiler Burner

　　1. Put out the flame after it floats due to the high and low air source.NcXBoiler Burner

　　Solution: adjust work pressure and restart.NcXBoiler Burner

　　2. When the flame detector system is in trouble and running, the grounding device of the flame detector probe, or when it is very dirty, all normal flame cannot be detected, indicating that the engine has stalled.NcXBoiler Burner

　　Solution: adjust the specific position of the probe and clean the surface layer of the probe.Restart.NcXBoiler Burner

　　3, power circuit system fault switch power ups and downs or missing phase, resulting in the process of engine stall.NcXBoiler Burner

　　Solution: contact the welder to check the switching power supply and wiring method.NcXBoiler Burner

　　(3) the combustion engine does not operate system fault press the operation switch button for a long time the combustion engine does not operateNcXBoiler Burner

　　1. Failure of the external connecting system; the external connecting temperature or working pressure control cannot reach the lower limit of operation;Check temperature or working pressure preset values regularly.NcXBoiler Burner

　　2, the internal structure of the combustion machine even if the standard air pressure is too high or too low, the wind pressure switch often closed can not find the closure, the air inlet mechanism is not in place, will be shown, step by step to take routine inspection.NcXBoiler Burner

　　The above is small make up for you to introduce the combustion engine system fault detection method and solution, I hope to help you ~NcXBoiler Burner
