Machine characteristics:
1. Steel frame
2. The standard type of protection class for all road and Marine generators is IP21, IP22 and IP23 as optional protection class, which can prevent damage caused by water droplets within 60 degrees in the vertical direction, but the rated power is reduced by 5%
3. Single fulcrum generator adopts multi-specification disc coupling, which is easy to be connected with various engine flywheels
4, the use of sealed ball bearing, no need to add grease
Generator electrical characteristics
1. Insulation grade H
2. All the generator stator windings are wound with 2/3 pitch, which can effectively eliminate the third harmonic of voltage
3. Stable voltage adjustment rate is ± 0.5%
4. The excitation stator is equipped with permanent magnets, so the generator will not lose magnetism and can always build voltage
Type of generator
Generators take many forms, but their operating principles are based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of its structure is: with the appropriate magnetic and conductive materials to form a magnetic induction magnetic circuit and circuit, in order to generate electromagnetic power, to achieve the purpose of energy conversion.
The classification of generators can be summarized as follows: DC, AC, synchronous and asynchronous (rarely used) generators
Alternator can also be divided into single-phase generator and three-phase generator.
Structure and working principle
Generator usually by stator, rotor, end cover. Brush. Frame and bearings and other components.
The stator is composed of the frame, the stator core, the wire wrap winding, and other structures that hold these parts together.
Rotor by the rotor core, rotor magnetic pole (there is a magnetic choke. Magnetic pole winding, slip ring, (also known as copper ring. Collector ring, fan and rotating shaft and other components.
Through bearing, frame and end cover to the generator stator, rotor connected together, can make the rotor spinning in the stator, through access to slip ring must be exciting current, make the rotor, a rotating magnetic field of the stator coil cutting lines of magnetic force to do exercise, thus induced potential, through the terminal lead, in the loop, the current is produced. As a result of the brush and rotor connected to the place where there is a break, so that the rotor by a certain direction of rotation, the generation of alternating current so the family circuit circuit is the alternating current, referred to as alternating current. Our power grid output current frequency is 50 Hz can produce 60 Hz.

7. Every 250-300 hours: change the engine oil, change the oil filter and bypass oil filter, change the fuel filter, discharge oil in fuel tank when necessary, and tighten the triangle belt.
8. Check whether the core electricity of the radiator and air-cooled intercooler is blocked and whether it needs to be cleaned; check that there should be no bad parts in the air pipe and its hose joint and tighten the clamp; check that there should be no leakage at the oil inlet and outlet of the booster.
9, every 1200 hours, please check and adjust the valve clearance professionals and check before the adjustment, under the engine stop and cold every 2400 hours, please check the adjustment of fuel injector professionals to dismantle and, by the professional personnel to check the working state of the supercharger, and carries on the routine inspection of engine and generator parts, every six months, replace the coolant filter, every year, cleaning the cooler, replace the cooling fluid.
