1. Oil metamorphosis. Oil degeneration is usually caused by the leakage of cooling water and fuel into the oil pan. In addition, poor atomization of the injector and frequent thunder of the throttle during the engine operation will result in the diesel engine not being completely extinguished, causing the oil to degenerate.
2. Impurities such as sand particles and metal scraps entering the oil pipeline cause burning tiles. Damage of oil pump results in oil shutdown, unqualified bearing pad quality, change of coordination between journal and bearing pad, obstruction of oil passage, no delivery of smooth oil to friction, and lack of oil pressure will result in burning pad. Oil leakage is an important reason for the lack of oil pressure.
3. Oil level is too low, tractor uphill, acceleration and braking conditions may form oil surface of oil collector, inhalation air surface can not supply oil, if the operator did not find the oil pressure disappeared in time, continue driving, will immediately form a burning tile.
4. Other reasons, such as misuse of oil, overloading frequently, excessive load or tightly screwed oil pressure limiting valve bolts, result in excessive oil pressure, long-term low-load operation may also burn tiles. Friends of pilots should pay attention to prevent the use and maintenance of diesel engines in order to reduce the occurrence of trouble.
In recent years, the rapid development of the national economy has provided a sustained impetus for the steady and rapid development of China's power industry. At present, with the rapid growth of electricity demand in the whole country, the power supply can be steadily strengthened. As an important equipment in the power industry, the market of natural gas generating units has increased sharply.
Cleaning and maintenance of natural gas generating units is equally important for the life of generating units and normal operation and shipment. It is necessary to stop shutting down the natural gas generator set in order to clean up the false start of the gas turbine.
The appearance of natural gas generating units is clean, and the setting frequency depends on the condition. Before cleaning, all the dust, dirt, grease, water or any liquid on the outside should stop scrubbing carefully. Cleaning and ventilating mesh holes should clear up the dust. Assuming they enter the coil, it will form a coil overheating, which may destroy the insulation.
