WHEN A DIESEL ENGINE EXPERIENCES OIL, WATER, OR GAS LEAKAGE, IT CAN LEAD TO INCREASED FUEL CONSUMPTION, ACCELERATED COMPONENT WEAR, DECREASED POWER, AND OTHER MALFUNCTIONS. THEREFORE, IT IS NECESSARY TO REPAIR IT IN A TIMELY MANNER. THE FOLLOWING ARE THE CAUSES AND TREATMENT METHODS OF OIL LEAKAGE, WATER LEAKAGE, AND GAS LEAKAGE IN DIESEL ENGINES: 1 REASONS FOR OCCURRENCE(1) THE FRICTION AND WEAR CAUSED BY THE MUTUAL MOVEMENT OF PARTS DURING DIESEL ENGINE OPERATION GRADUALLY CHANGE THE GEOMETRIC SHAPE AND SIZE OF THE PARTS.(2) DUE TO IMPROPER USE AND MAINTENANCE, SUCH AS LOOSE SCREWS, DAMAGED SEALING RINGS AND GASKETS.(3) IMPROPER DISASSEMBLY AND INSTALLATION OF PARTS. NOT USING SPECIALIZED TOOLS DURING DISASSEMBLY AND ASSEMBLY, NOT FOLLOWING THE DISASSEMBLY AND ASSEMBLY PROCESS REQUIREMENTS, CAUSING DEFORMATION OF PARTS, DAMAGE TO CONTACT SURFACES, UNCLEAN SURFACES, AND LOOSE CONTACT SURFACES.(4) PARTS ARE AGING AND DETERIORATING. RUBBER OIL SEALS, WATER SEALS, ETC. ARE SUBJECT TO LONG-TERM CORROSION BY OIL OR WATER, RESULTING IN AGING AND DETERIORATION. 2 THE HARM CAUSED(1) OIL LEAKAGEOIL LEAKAGE IN THE LUBRICATION SYSTEM OF A DIESEL ENGINE CAN CAUSE A DECREASE IN THE OIL LEVEL IN THE OIL PAN, AND IN SEVERE CASES, IT CAN RESULT IN VARIOUS PARTS NOT RECEIVING LUBRICATION AND BEING BURNED. LEAKAGE OF DIESEL FUEL IN THE FUEL SUPPLY SYSTEM OF A DIESEL ENGINE CAN CAUSE AIR TO ENTER THE OIL CIRCUIT, MAKING IT DIFFICULT TO START THE DIESEL ENGINE. AT THE SAME TIME, IT CAN LEAD TO ENERGY WASTE, ECONOMIC LOSSES, AND LAND POLLUTION.(2) WATER LEAKAGEDIESEL ENGINE COOLING SYSTEM LEAKAGE NOT ONLY CAUSES TROUBLE IN ADDING WATER, BUT IN SEVERE CASES, IT CAN ALSO LEAD TO CYLINDER HEAD CRACKS. FOR WATER-COOLED DIESEL ENGINES, WATER LEAKAGE FROM THE CYLINDER LINER WATERPROOF RING CAN DILUTE THE OIL IN THE OIL PAN, ACCELERATING THE WEAR OF PARTS AND, IN SEVERE CASES, CAUSING TILE BURNING ACCIDENTS.(3) AIR LEAKAGELEAKAGE AT THE JOINT BETWEEN THE DIESEL ENGINE BODY AND CYLINDER LINER CAN BURN OUT THE CYLINDER GASKET, MAKING IT DIFFICULT TO START THE DIESEL ENGINE AND REDUCING POWER. LEAKAGE IN THE INTAKE SYSTEM OF A DIESEL ENGINE CAN CAUSE DUST TO BE SUCKED INTO THE CYLINDER, ACCELERATING THE WEAR OF COMPONENTS SUCH AS CYLINDER LINERS, PISTONS, PISTON RINGS, VALVES, AND GUIDES, MAKING IT DIFFICULT TO START THE DIESEL ENGINE, INCREASING FUEL CONSUMPTION, AND REDUCING POWER. 3 PROCESSING METHOD(1) ADD CUSHION TO TREAT LEAKAGE METHODTHE LEAK PROOF GASKET AT THE DIESEL ENGINE OIL PIPE JOINT CAN BE SEALED BY ADDING A LAYER OF DOUBLE-SIDED SMOOTH THIN PLASTIC GASKET ON BOTH SIDES OF THE LEAK PROOF GASKET AND TIGHTENING IT FIRMLY TO PREVENT LEAKAGE.(2) LACQUER SLICE LIQUID LEAK TREATMENT METHODLEAKAGE AT THE JOINTS OF DIESEL ENGINE FUEL TANK, WATER TANK, CRANKCASE, ETC. CAN BE TREATED BY SOAKING THE PAINT IN ALCOHOL AND APPLYING THE PAINT SOLUTION TO THE CLEANED JOINTS. BUT THE COST OF LACQUER CHIPS IS HIGH, AND THEY ARE USUALLY ONLY USED IN EMERGENCY SITUATIONS.(3) OIL BASED LEAK CONTROL METHODWHEN THE PAPER PADS ON THE OIL PAN, CYLINDER HEAD, GEAR CHAMBER COVER, CRANKCASE COVER, ETC. OF A DIESEL ENGINE LEAK, AS LONG AS THE PAPER PADS ARE INTACT AND THE JOINT SURFACE IS CLEAN, A LAYER OF BUTTER CAN BE APPLIED TO BOTH SIDES OF THE PAPER PADS, AND THE BOLTS CAN BE TIGHTENED TO PREVENT LEAKAGE. IF USING A NEW PAPER PAD, SOAK IT IN DIESEL FOR 10 MINUTES BEFORE INSTALLATION, THEN REMOVE AND WIPE IT CLEAN. APPLY A LAYER OF BUTTER ON THE JOINT SURFACE BEFORE REINSTALLING.(4) LIQUID SEALANT LEAKAGE TREATMENT METHODWHEN SOLID GASKET DEFECTS (SUCH AS PITS, GROOVES, AND RUPTURES) OCCUR ON DIESEL ENGINES, RESULTING IN INTERFACE LEAKAGE AND DESTRUCTIVE LEAKAGE, LIQUID SEALANT SHOULD BE APPLIED TO THE CLEANED SOLID GASKET JOINT SURFACE. AFTER CURING, IT CAN FORM A UNIFORM, STABLE, AND CONTINUOUSLY ADHERED PEELABLE THIN FILM GASKET, WHICH CAN PREVENT ALL LEAKAGE PHENOMENA.(5) ANAEROBIC ADHESIVE LEAK CONTROL METHODWHEN THERE IS LEAKAGE AT THE VENTILATION BOLTS, DOUBLE HEADED BOLTS, SCREW PLUGS, ETC. ON THE DIESEL ENGINE, APPLY ANAEROBIC ADHESIVE TO THE CLEANED BOLTS, THREADS, OR SCREW HOLES, WHICH CAN QUICKLY SOLIDIFY INTO A THIN FILM, FILL THE GAPS IN THE PARTS, AND WITHSTAND HIGH PRESSURE. AT THE SAME TIME, IT ALSO HAS STRONG SHOCK RESISTANCE AND ANTI LOOSENING FASTENING FUNCTION. IF USED FOR THE THREAD OF HIGH-PRESSURE OIL PIPE JOINTS IN DIESEL ENGINES, THE LEAKAGE CONTROL EFFECT IS BETTER.(6) SIZE RECOVERY GLUE LEAK CONTROL METHODWHEN THERE IS LEAKAGE AT THE SHAFT AND SHAFT SLEEVE, BEARING AND BEARING SEAT, VALVE AND VALVE SEAT, SELF TIGHTENING OIL SEAL, FELT CUP, AND PACKING ON THE DIESEL ENGINE, SIZE RECOVERY GLUE CAN BE APPLIED TO THE WORN PARTS OF THE CLEANED MATING PARTS. AFTER CURING, A WEAR-RESISTANT, HEAT-RESISTANT, AND MECHANICALLY STRONG THIN FILM LAYER IS FORMED. THEN, MECHANICAL PROCESSING SUCH AS TURNING, BORING, SCRAPING, AND FILING CAN BE CARRIED OUT TO RESTORE THE GEOMETRIC SHAPE AND MATING ACCURACY OF THE PARTS, THEREBY SOLVING THE LEAKAGE PROBLEM.(7) GLUE REPAIR METHOD FOR TREATING LEAKSWHEN SAND HOLES AND AIR HOLES IN THE BODY PARTS OF A DIESEL ENGINE, SUCH AS THE FUEL TANK, WATER TANK, OIL PIPES, WATER PIPES, ETC., CAUSE LEAKAGE, APPLY ADHESIVE TO THE CLEANED DAMAGED AREAS TO ACHIEVE THE EFFECT OF TREATING LEAKAGE.
