Cummins serves customers with International Warranty Services (IWS).C series 27.5 kVA diesel engine generator set working principle and structure introduction.

C series 27.5 kVA diesel engine generator set working principle 

I. The basic structure of a C series 27.5 kVA diesel engine generator is composed of a diesel engine and a generator. The C series 27.5 kVA dg set drives the generator to generate electricity.

1. The basic structure of a dg set: it is composed of cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston pins, connecting rods, crankshafts, bearings and flywheels. The dg genset is generally a single-cylinder or multi-cylinder four-stroke diesel engine. We Bidirection Power Technology will only talk about the basic working principle of a single-cylinder four-stroke diesel engine: the starter of a diesel engine generator is to turn the crankshaft of the diesel engine generator set by manpower or other engine power to make the piston sealed at the top of the cylinder In reciprocating movement up and down. The piston completes four strokes in motion: intake stroke, compression stroke, combustion and power (expansion) stroke, and exhaust stroke. When the piston moves from top to bottom, the intake valve opens, and the fresh air filtered by the air filter enters the cylinder to complete the intake stroke. The piston moves from bottom to top, the intake and exhaust valves are closed, the air is compressed, the temperature and pressure increase, and the compression process is completed. When the piston is about to reach its apex, the fuel injector sprays the filtered fuel into the combustion chamber as a mist and mixes it with high-temperature and high-pressure air and immediately ignites and burns. The resulting high pressure pushes the piston down to perform work and pushes the crankshaft to rotate to complete the work. Work stroke. After the work stroke is completed, the piston moves from bottom to top, the exhaust valve opens to exhaust, and the exhaust stroke is completed. The crankshaft rotates half a turn per stroke. After several working cycles, the diesel engine gradually accelerates into work under the inertia of the flywheel, and the crankshaft of the dg set rotates to drive the generator to generate electricity.

2. The C series 27.5 kVA generators include DC generators and AC generators.

The DC generator is mainly composed of a generator shell, a magnetic pole core, a magnetic field coil, an armature and a carbon brush. Working principle of power generation: When the diesel engine generator drives the generator armature to rotate, the armature coil cuts the magnetic lines of force in the magnetic field due to the remanent magnetism of the generator's magnetic pole core. According to the principle of electromagnetic induction, the current is generated by magnetic induction and output through the carbon brush to the alternator is mainly composed of a number of permanent magnets (called a rotor) with alternating north and south poles made of magnetic materials and an armature coil (called a stater) made of silicon cast iron and wound with multiple sets of serial coils. Working principle of power genset generator: The rotor is driven by the dg set to cut the magnetic lines of force in the axial direction. The alternating magnetic poles in the stater form an alternating magnetic field in the coil core. The rotor rotates once, and the direction and size of the magnetic flux are changed many times. Due to the changing effect of the magnetic field, In the coil, an induced current of varying size and direction will be generated and the current will be delivered by the dg stater coil. In order to protect the electrical equipment and maintain its normal operation, the current generated by the diesel engine generator also needs a regulator for adjustment control and so on.

Next, we will mainly introduce the characteristics of diesel generator sets: Diesel generator sets are technologies that integrate multiple disciplines such as diesel engines, generators, and automatic control. Diesel generator sets are power generation equipment powered by diesel engines. Compared with common steam generator sets, water turbine generator sets, gas turbine generator sets, atomic energy generator sets and other power generation equipment, it has compact structure, small footprint and high thermal efficiency, quick start, flexible control and easy fuel storage.

According to structural point, the structural characteristics of Cummins engines: 1. Most of them are equipped with the company's unique PT fuel system (except for the B and C series). 2. All use ω combustion chamber. 3. The cam followers are all rollers. 4. Most of the fuel and oil passages are drilled in the cylinder block and cylinder head. 5. Wet cylinder liner, which is phosphated. 6. The crankshaft is forged with alloy steel and the journal is induction hardened. 7. The first ring groove of all pistons has a nickel alloy cast iron insert to increase the life of the ring groove.
