THE SAFE OPERATION OF DIESEL GENERATORS PLAYS A DECISIVE ROLE IN ENSURING THE NORMAL OPERATION OF THE POWER SYSTEM AND THE QUALITY OF ELECTRICAL ENERGY. AT THE SAME TIME, DIESEL GENERATORS THEMSELVES ARE VERY VALUABLE ELECTRONIC COMPONENTS. THEREFORE, DIFFERENT FAULT SYNDROMES AND ABNORMAL OPERATING CONDITIONS SHOULD BE EQUIPPED WITH IMPROVED RELAY EQUIPMENT TO IMPROVE THEIR PERFORMANCE. HERE IS THE SEQUENCE FOR DETERMINING THE DIESEL GENERATOR:THE GENERAL PRINCIPLE FOR FAULT DIAGNOSIS OF DIESEL GENERATORS IS TO COMBINE THE PHENOMENA OF SIMPLE STRUCTURE, CONTACT AND CLARIFICATION PRINCIPLES WITH PRACTICAL, COMPLEX, FROM THE OUTSIDE TO THE INSIDE, TO FIND THE CAUSE, ACCORDING TO THE AMERICAN SECTION.1. DETERMINE THE FAULT FROM AN OVERALL ANALYSISFAULT DIAGNOSIS SHOULD BE COMPREHENSIVE. THE DIESEL GENERATOR SYSTEM, COMPONENTS, AND PARTS ARE CLOSELY RELATED, AND A COMPONENT OR PART OF A SYSTEM OR FAULT WILL INEVITABLY INVOLVE OTHER SYSTEM COMPONENTS OR PARTS. THEREFORE, THE FAULT PHENOMENON CANNOT BE VIEWED IN ISOLATION, AND THE CAUSE OF THE FAULT SHOULD BE ANALYZED AS A WHOLE TO PROMPTLY ELIMINATE THE FAULT.2. TO IDENTIFY THE MALFUNCTION OF THE DIESEL GENERATOR, BLIND DISASSEMBLY SHOULD BE AVOIDEDDO NOT DISASSEMBLE PARTS FOR DIESEL ENGINE FAULT DIAGNOSIS. ESPECIALLY FOR FOREIGN UNITS OR SPARE PARTS, IN ORDER TO AVOID BLIND DEMOLITION AND UNLOADING, THEY MAY INITIALLY RECOVER UNTIL THE FAULT CANNOT BE RESOLVED. AT THE SAME TIME, DISASSEMBLY AND REASSEMBLY CAN AFFECT THE FITTING OR SEALING SURFACES OF SOME PARTS OF THE DIESEL ENGINE THAT OPERATE WELL, DAMAGE THE ACCURACY OF DIESEL ENGINE ASSEMBLY, AND REDUCE THE PERFORMANCE OF THE DIESEL ENGINE.3. WHEN A MALFUNCTION IS DETECTED, ONE SHOULD BE CAREFUL, OBSERVE, LISTEN, FEEL, SMELL, AND CONDUCT A COMPREHENSIVE INSPECTIONIN THE ABSENCE OF ADVANCED DETECTION EQUIPMENT, DIRECT FAULT DIAGNOSIS METHODS ARE GENERALLY USED, WHICH CAN BE SUMMARIZED AS: SIGHT, HEARING, TOUCH, AND SMELL.SEE: IN THE OPERATION PROCESS AND EXTERNAL CHARACTERISTICS OF DIESEL GENERATORS, SUCH AS ABNORMAL EXHAUST PIPES; THE EXHAUST PIPE IS RED; THE COLOR OF THE OIL IS NORMAL, WHETHER THE OIL IN THE OIL PAN HAS INCREASED; THE RELEASE OF OIL CONTAINING WATER; FUEL SYSTEM, COOLING SYSTEM, AND LUBRICATION SYSTEM ARE LEAKING WATER, AND DIESEL IS LEAKING; IS THERE ANY ABNORMALITY IN THE MACHINE INSTRUMENT INDICATION; ALL MOVING PARTS OF THE NUT ARE LOOSE; DIESEL ENGINE OPERATION VIBRATION, SWAY, ETC.LISTEN: MAINLY LISTEN TO ABNORMAL NOISE DURING THE OPERATION OF THE DIESEL GENERATOR, AND DETERMINE THE NATURE AND LOCATION OF THE FAULT ABNORMAL SOUND.CONTACT: TOUCH IT. SUCH AS FLUCTUATIONS IN HIGH-PRESSURE OIL PIPES, UNIT IMPACT, TEMPERATURE OF OIL PIPES OR OIL, AND INDICATION OF OIL TEMPERATURE INDICATORS. GUIDANCE CAN QUICKLY MANUALLY TEST THAT THE TEMPERATURE OF EACH EXHAUST MANIFOLD IS CONSISTENT. IF A CYLINDER IS TOO LOW, IT CAN BE CONSIDERED BAD, BUT WE SHOULD BE CAREFUL TO AVOID BURNS.SMELL: SMELL FROM FAULT DIAGNOSIS. THE WORKING PROCESS OF A ODORLESS DIESEL GENERATOR AND DIESEL ENGINE; IS THERE A SMELL OF BURNING OIL, ETC.
