Identification and treatment of simple faults in generator sets
公司来告诉你，发电机组为何会缺点？ Guangzhou generator repair company to tell you, why are generators disadvantages? First, the diesel engine emits black smoke 1. Engine overload; 2. Poor fuel quality; 3. The air filter is blocked; 4. Poorly sealed valve components; 5. Piston ring is worn or cracked; 6, turbocharger operation failure; 7. Cylinder liner or piston wear / scratch; 8. The fuel injection nozzle has poor plugging and needs to be adjusted. Second, the diesel engine emits white smoke 1. There is water in diesel oil; 2. Diesel engine oil (supercharger oil); 3. The fine coupling parts of the fuel injector have failed, or the fuel injection time is incorrect; 4. Excessive wear of valve guide and valve, oil leaks into the cylinder. Third, the diesel engine shows a burning phenomenon 1. The oil quality is too poor; 2. Low oil pressure; 3. Oil pump operation fails; 4. The diesel engine is hot due to lack of water; 5. The bearing bush gap is too large, causing the oil pressure to be too low. Fourth, the reason for low oil pressure 1. The wear of the giant and fine bearing bushes is too large; 2. The oil filter is blocked; 3. The oil pump wears too much; 4. The filter and filter are dirty; 5. The oil quality is too poor or the oil application time is too long. V. Diesel engine water temperature is too high 1. Water pump wear; 2. The thermostat is damaged; 3. The water tank is too dirty; 4. The lack of coolant; 5. Fan belt and water pump belt are too loose. 6. Under high load, the exhaust pipe and supercharger will turn red 1. The air filter is blocked and the ventilation is poor; 2. The fine coupler of the fuel injector fails; 3. The intercooler is too dirty and the air intake is lacking; 4. Supercharger operation fails; 5. The camshaft, follower arm assembly and rocker arm assembly are excessively worn. Large power loss during diesel engine operation 1. The cylinder group is too worn out; 2. The operation of the fine coupler of the fuel injector fails; 3. Oil pump operation fails; 4. Supercharger operation fails. Eight, the exhaust of the diesel engine has a large phenomenon or there is a white exhaust from the exhaust pipe 1. Excessive wear of cylinder components; 2. Oil pan has water; 3. There is a pull cylinder phenomenon. Nine, diesel engine speed is not stable 1. The fuel system is blocked by air or diesel grid; 2. The oil pump is damaged due to lack of oil supply; 3. The speed regulation system fails. Ten, oil pan has water 1. Water leakage from the smoke pipe or muffler; 2. Cylinder liner split; 3. The cylinder is split; 4. The cylinder head is split.
