Generator is a complete set of mechanical equipment to convert diesel into electric energy, composed of power system, control system, muffler system, shock absorption system, exhaust system, driven by water turbine, steam turbine, diesel engine or other power mechanical drive, the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy to the generator, and then converted by the generator into electrical energy. Output to the use of electrical equipment, generators in industrial and agricultural production, national defense, science and technology and daily life have a wide range of uses, in recent years with the progress of technology, as a family emergency power supply and field travel power quality choice, lightweight portable small generator sets have also begun to enter the daily life of residents. Next, let's follow the generator set manufacturer to understand some common problems in the use of the generator set.
Diesel engine oil generally through the piston ring and ring groove gap, valve and conduit gap into the combustion chamber, the direct cause of its jumping into the first piston ring near the top dead center due to its movement speed dropped sharply, then attached to it above the lubricating oil thrown into the combustion chamber to go, so the piston ring and piston with the gap, piston ring scraping oil and scraping capacity, The pressure in the combustion chamber and the oil viscosity are closely related to the oil consumption.
Due to the bending of the connecting rod and the failure of the body shaping tolerance to meet the requirements of the piston deviation (which is marked by the wear marks of the cylinder liner and piston along the two ends of the pin hole axis on one side of the piston ring bank and the other side of the piston skirt), is also an important reason for the increase in oil consumption.
The use of twisted ring and combined oil ring has an obvious effect on reducing oil consumption, especially the combined oil ring is light in weight, the three-piece structure does not pump oil, the flexibility of itself, the adaptability of the cylinder wall is good, the expansion ring makes the side of the oil ring close to the ring groove.
From the operating conditions, the oil viscosity used is too low, the engine speed and water temperature are too high, the cylinder liner deformation exceeds the limit, the number of starts and stops is frequent, the engine parts wear is too large, the oil level is too high, and so on will increase the oil consumption.
Therefore, if it is found that the fuel consumption of the diesel generator set increases compared with the usual fuel consumption, we should first find out what is caused by it, and then the right medicine, effectively save fuel consumption energy, reduce the cost of unnecessary expenditure.
