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 without knowing how to use the generator. As the Internet grows morePlus, people start buying things instead of buying them nearby. They buy them directly 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 plonger than the other two. 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 pillar to secure the wire. If you want to connect the generator power to the mains, you need to connect the wire from the generator plug to your mains. Above the wires there is no wire. need to buy a plug right now.

Basic Structural Principles of Diesel Generators

Crankshaft Connecting Rod Mechanism! Air intake! Lubricating System! Cooling system! Oil supply system!Boot the system!

The main mechanical components of a diesel engine generally include: the body, the crank rod mechanism, the valve system, the fuel system, the lubrication system, the cooling system and the electrical system.

1. Body: It is the skeleton of the diesel engine, which supports and installs other components, including: cylinder block, cylinder liner, cylinder head, cylinder gasket, oil pan, flywheel housing engine, the timing gear housing. , front and rear feet.

2. Crank Connecting Rod Mechanism: This is the main moving part of the diesel engine. It can convert the energy generated by fuel combustion into mechanical energy through the piston, piston pin, connecting rod, crankshaft and flywheel. . Including crankshaft, connecting rod, piston, piston pin, piston pin circlip, piston pin bushing, segpiston bearing, main bearing, connecting rod bearing, thrust bearing, front and rear crankshaft oil seals, flywheel, shock absorber, etc.

3. Valve Timing Mechanism: It regularly opens and closes the intake and exhaust valves. Including timing gears, camshafts, lifters, push rods, rocker arms, valves, valve springs, valve seats, valve guides, valve lock blocks, hoses intake and exhaust systems, air filters, silencers, compressors, etc.

4. Fuel supply system: According to the needs of the diesel engine, diesel is regularly and quantitatively supplied to the combustion chamber for combustion. Including diesel tank, fuel pipe, diesel filter, fuel injection pump, fuel injector, etc.

5. Lubrication system: suppliedit from lubricating oil to various moving friction pairs, including oil pumps, oil filters, pressure regulating valves, pipelines, instruments, oil coolers, etc.

6. Cooling System: It dissipates the heat generated by the diesel engine to the atmosphere. Including water tank, water pump, fan, water pipe, thermostat, water filter, fan belt, water temperature meter, etc.

7. Electrical Appliances: Auxiliary equipment for starting, lighting, monitoring and operation. Including generators, starters, batteries, relays, switches, wiring, etc.

Detailed information:

The characteristics of traditional diesel engines: better thermal efficiency and economy. Diesel engines use compressed air toincrease the air temperature so that the air temperature exceeds the self-ignition point. of diesel. When diesel is injected, the diesel spray and air are mixed while igniting and burning on its own. Diesel engines therefore do not require an ignition system.

At the same time, the fuel supply system of diesel engines is relatively simple, so the reliability of diesel engines is better than that of gasoline engines. Because they are not subject to the knock restrictions and need for spontaneous combustion of diesel, diesel engines have a high compression ratio. Thermal efficiency and economy are better than gasoline engines. At the same time, at equal power, diesel engines have high torque and low rpm at maximum power, making them suitable for use in trucks.

However, due to the high working pressure of the motorur diesel, the parts involved must have high structural strength and rigidity, so the diesel engine is relatively bulky and large in size, as well as the fuel injection pump; the diesel engine nozzle requires high manufacturing precision, so the cost is relatively high. Additionally, the diesel engine runs rough, vibrates and makes loud noises. Diesel is not easy to evaporate and it is difficult to start when the car is used. it is cold in winter. Due to the above characteristics, diesel engines were once generally used in large and medium-sized trucks.

The difference between imported and domestic diesel generator sets

The basic structure of a diesel generator is composed of a diesel engine and generator It is composed of a diesel engine which drives a generator to produceelectricity.

Let's start with the basic structure of a diesel engine: it consists of cylinders, piston, cylinder head, intake valves, exhaust valves, piston pins, connecting rods, crankshaft, bearings and flywheels. The diesel engine of a diesel generator is generally a single-cylinder or multi-cylinder four-stroke diesel engine. Below I will only talk about the basic operating principles of a single-cylinder four-stroke diesel engine: The diesel engine is started by.The crankshaft of the diesel engine is rotated by labor or other force to cause the piston to move back and forth up and down in the cylinder sealed from the top.

The piston makes four strokes in motion: intake stroke, compression stroke, combustion and power stroke (expansion), and exhaust stroke. When the piston moves up and down, the inlet valve opens and theFresh air filtered by the air filter enters the cylinder to complete the intake stroke.

The piston moves up and down, 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 highest point, the fuel injector sprays the filtered fuel into the combustion chamber in the form of mist, mixing with the air at high temperature and high pressure, and then s ignites and immediately burns on its own. The high pressure formed pushes the piston down to do the work, causing the crankshaft to rotate, completing the action. After the power stroke is completed, the piston moves up and down, the exhaust valve opens to vent, and the exhaust stroke is completed.

The crankshaft rotates half a turn each stroke. After several work cycles, theDiesel engine gradually accelerates to operate under flywheel inertia.

Many consumers think that the quality of domestically produced machines is not very good, but this is not the case. In fact, the quality of domestic diesel engines is very good. The key is knowing if what you are buying is original and authentic. If you buy a fake, the quality is indeed very poor. The situation of imported fake diesel generator sets is also very serious, and the quality is also very poor.

It is unlikely that many insiders will be able to distinguish remanufactured imported diesel engines by their appearance when not actually in use, but fake domestic diesel generators can be identified by will by the initiates. Even if we avoid counterfeits, the quality of most brands of imported machines is not better than that of domestic machines, andsome brands are not even as good as some famous brands of domestic machines. Domestic engines are characterized by their durability and adaptability to use in harsh environments, while imported diesel engines have relatively high requirements for working conditions. They are generally used in better environments such as firefighting and are more suitable for purchase when used less often. .
