Generating units are other sets of energy into electrical energy complete sets of mechanical equipment, by the power system, control system, silencer system, shock absorption system, exhaust system components. The generator unit in the diesel engine unit to reduce the volume of the rapid increase in temperature, to achieve the ignition of diesel. Diesel is lit, mixed gas violent combustion, the volume of rapid expansion, to promote the piston down, known as work.
The cylinder in a certain order in turn, the role of the thrust on the piston through the connecting rod into the power to promote the crankshaft rotation, thus driving the crankshaft rotation. Using the principle of electromagnetic induction, the generator will output the induced electromotive force, the closed load circuit can produce current.
The engine is the chemical energy into mechanical energy of the machine, its transformation process is actually the process of working cycle, simply is through the combustion of fuel in the cylinder, generate kinetic energy, driving the engine cylinder piston reciprocating movement, thus The connecting rod connected to the piston and the crank connected to the connecting rod, around the crankshaft center for reciprocating circular motion, and the output power. We analyze this process: a work cycle includes four piston strokes (the so-called piston stroke refers to the piston from the top dead center to the distance between the bottom point of the process): intake stroke, compression stroke, expansion stroke Travel) and exhaust stroke.
After a period of operation, the generator set should check regularly. , Air filter obstruction indicator, coolant level, radiator and external ventilation, the engine belt group, fuel oil supply and so on. Each time the unit is running for 200 hours, it is necessary to check the valve clearance and check the injector: the generator unit is running for 400 hours each time the unit is running for 200 hours after the operation of the new unit. After the need to check and adjust the drive belt, if necessary, to replace, check the cleaning radiator chip and discharge the sludge inside the fuel tank; every 600 hours or at least every 12 months, need to replace the lubricating oil and lubricating oil filter; The frequency of the oil change cycle varies depending on the quality of the different lubricants and the sulfur content of the fuel and the consumption of the lubricating oil generator. For every 800 hours of operation, change the oil and water separator and the fuel filter to check the turbocharger Whether to leak, check the intake pipe for leaks, check and clean the fuel pipeline; every 1200 hours after the operation to adjust the valve clearance; every 2000 hours after the operation, replace the air filter and coolant, thoroughly clean the tank radiator chip and water ; Every 2400 hours after the operation, check the injector, thoroughly check the cleaning turbocharger, a comprehensive inspection of the engine equipment.
