It refers to the diesel generator running at idle speed, but the regularity is not strong, and there are jitter, and diesel generator in the rapid deceleration, shift or easy to stall with load, this phenomenon is caused by the governor failure. The main causes of occurrence are the following.
The silencer of diesel generator machine is developed according to the principle of anti-noise, anti-injection and compound anti-noise. It has the advantages of large volume, small volume, light weight, stainless steel manufacture, easy corrosion and convenient installation. The sound wave is attenuated by expanding cavity and perforated plate, and the sound becomes heat energy. The principle of which is mostly multistage throttling and lowering pressure, high pressure steam passing through a control flow in the muffler and entering the pressure relief body after a large volume diffuser.
According to the experience of various countries in the world on diesel generator sets, the emergence of such market demand peaks is inevitable. This is not only a question of regulating the power supply capacity, but also a possible reason for the safety of the power grid, such as the United States, which appeared in the past few years. Canada's massive blackouts and last year's European blackouts, India's biggest blackout this year, left its 600 million people without electricity. The main reason is not that the power supply is insufficient, but that the power grid cannot bear too much load over the years, causing the power grid to be paralyzed.
The two-phase operation of three-phase diesel generator sets is a common cause of damage to diesel generating units. Why is the diesel generator set equipped with fuse protection, magnetic starter additional thermal relay protection, circuit breaker over-current protection, can not be a good two-phase operation of the generator set effective protection?
