5KW diesel generator diesel generator on combustion chamber components are exposed to stress in addition to the above have been analyzed, and in casting foundry there are also the inevitable stress, but also by the diesel engine running on the piston due to its own inertia force mechanical stress. In these stresses, the high frequency, but also low frequency. Therefore, the stress is part of the combustion chamber by a certain relationship stack up overall stress. For reliable operation of the combustion chamber components, must have a reasonable structure to ensure that. 5 kilowatts diesel generator Product parameters: KZ6800SE-5KW silent electric start diesel generator Model KZ6800SE rated frequency 50Hz Rated voltage 220V maximum rated power 5.0kw 5.5kw DC power output 12V / 8.3A Phase Single Engine Model Engine Type KZ186FAE wind cold, single-cylinder, four-stroke, direct injection Bore × 86 × 72mm stroke 418cc engine displacement engine maximum power rated power 5.8KW 6.6KW rated engine speed 3000RPM lowest fuel consumption rate 270g / kw.h Oil Capacity 1.7L startup mode electric start fuel type 0 # (summer) -10 # (winter) -35 # (cold) light diesel oil Model SAE10W30 (CD and above) Fuel tank capacity 16L Continuous working time 10.5h Noise (7m) dB 68 dimensions of 950 × 560 × Structural features 760mm Weight 155KG diesel generator combustion chamber components: the degree of enhancement contemporary novel long stroke diesel engine has reached a very high level of mechanical and thermal loads combustor components are nearing the limit of its material permitted limits. In order to reduce the mechanical stress of the piston top plate, the thickness of the top of the piston should be increased. Increasing the thickness of the piston roof will lead to increased thermal stress. So the two contradict each other. Such conflicting in the cylinder head and cylinder liner as well. The use of "thin-walled strong back" structure is an effective way to both mechanical stress and thermal stresses. The so-called thin-walled chamber wall is heated parts thinner to reduce the thermal stress. And strong back is provided on the back of a thin strong support, in order to reduce mechanical stress. In the existing variety of "thin-walled strong back" structure, drilling is the optimum form of cooling. Thus, the contemporary novel long stroke diesel engine combustion chamber cooling structure they use a drill. In the cooling water holes of the cylinder head and the cylinder liner drilled distribution. Contact cooling water holes from surface fire close (the nearest about 20mm), which together form the layer of water holes thermal barrier, blocking out heat transfer. That is, regardless of the cylinder liner or the cylinder head, the cooling water holes in fact they are divided into two portions of hot and cold, the heat flow can be limited to almost a narrow region of the combustion chamber wall surface and the cooling water between channels. Therefore, the hot zone is very thin - thin-walled, reducing thermal stress; cold zone is very thick - strong back, reducing mechanical stress. Due to the cooling effect of well drilling, it has been widely used in modern large-scale strong load diesel generators.
