The national standard for gasoline generators is to generate 270 grams of gasoline per kilowatt hour.
At full load, the fuel consumption of 1 kW per hour is 1*0.27 = 0.27 kilograms. Converted to liters, it is as follows: the weight divided by the specific weight of gasoline 0.722 is equal to 0.374 liters. that is, at full load, a 1 kW gasoline generator consumes 0.374 liters of fuel per hour, which is 0.374 times the capacity of 5 kW.
The oil change interval for small domestic gasoline generators is 220 to 250 hours or one month. If Category 2 engine oil is used, the engine oil can be extended for up to 400 operating hours before replacement, but the oil filter (filter element) must be replaced.
Replacing the generator oil can well guarantee the stable use of the generator set, which also effectively extends the service life of the generator set.electrogen to some extent, so it must be accurate when using the generator. . Determine the engine oil change time.
Detailed information:
The noise of gasoline generator sets has spectrum characteristics broadband, and requires quiet equipment that can withstand high air flow speeds, high temperatures and pressures, and is not afraid of water and humidity. When the temperature increases, the performance of the silencer does not change much. According to this situation, composite silencers with micro-perforated plates. are often used in treatment.
Using a thin steel plate of 0.5-1mm, it is made into a double-layer micro-perforated plate silencer with a hole diameter of 0.5-1mm and a perforation rate of 1% to 3%. protection against medium noise absorption effect andhigh frequency. When there are several layers, the thickness of the cavity depends on the absorption frequency band. When the low frequency is 125-250 Hz, the cavity thickness is 150-220 mm. When the average frequency is 500-1000 Hz, the cavity thickness is 80-120 mm.
