How to wire a diesel generator
The engine starts first, and the motor drives the electric ball through the flywheel to generate electricity, then transmits it to the load. A 24 V battery is required to start the engine. After starting, it can work normally after continuous fuel supply. There is a start relay on the motor with 4 terminals. The left and right ends are connected to the positive and negative poles, and the upper and lower ends are connected to the start signal circuit. Can you understand what I'm saying? The black thing in the middle of the diesel generator in the link below is the starter and starting relay. You need two for high power and one for low power.
Nowadays, many people buy diesel generators but don't know how to use the generator. As the Internet Growse more and more people are starting to buy things instead of buying them directly from nearby. from the manufacturer. But the more you buy online, the more problems you encounter. We have already met some customers who cannot connect the plug wires. In fact, the generator plug wiring method is very simple. Now I will briefly talk about the method of wiring the generator whether it is a gasoline generator or a diesel generator. . The methods of wiring generators are all the same. The first step is to purchase a plug. The power of the socket depends on the power of the device you want to carry. First, use a razor blade to open the plug cover that came with the generator. Remove the cover again and you will see that there are three pillars inside the generator plug, two of which are the same length and one pillar is much longer than thetwo other pillars. Next, our wiring is connected to two pillars of the same length. Since the socket has two wires, one is the neutral wire and the other is the hot wire, for now we just need to replace the plug of the regular socket with the special plug of our generator. At this point we just need to connect the wire from the socket we purchased to the generator plug. The two wires are connected to the two pillars circled in red. The final step is to use the two screws on the post to secure the wire. If you want to connect the generator power to the mains, you need to connect the generator plug wire to your mains. you don't need to buy a plug at this time.
Since the flammability of diesel is lower than that of gasoline, the diesel engine does not need to be ignited. Diesel can be burned at high pressure.
Diesel. the engine inhales during the intake stroke. Thisst clean air. When the compression stroke approaches the end, the diesel fuel pressure increases to more than 10 MPa via the injection pump and is injected into the cylinder via the injector. It mixes with high temperature compressed air in a short time. form a combustible mixture. Due to the high compression ratio of diesel engines (generally 16-22), the air pressure in the cylinder can reach 3.5-4.5MPa at the end of compression, and the temperature can reach 750-1000K ( while the mixture pressure of gasoline engines at this time will be 0.6-1.2 MPa, the temperature reaches 600-700 K), which significantly exceeds the self-ignition temperature of diesel. Therefore, once diesel is injected into the cylinder, it ignites immediately and burns after mixing with air in a very short time. The air pressure in the cylinder quickly increased to 6-9MPa and the temperature also reached 2000-2500K. pushhigh pressure gas When the engine is running, the piston moves down and drives the crankshaft to rotate to do work, and the exhaust gas is also discharged to the atmosphere through the exhaust pipe.
The diesel engine uses the compression stroke to compress the fuel and air mixture until the temperature reaches its ignition point and burns to achieve the ignition and combustion target. combustion
