Characteristics of salient-pole generators: The air gap between the stator and the rotor is non-uniform. The air gap under the pole shoe is relatively small, while the air gap between the two poles is relatively large. That is to say, the magnetic reluctances of the direct axis and the quadrature axis of the salient-pole synchronous generator are different. Therefore, the armature magnetomotive force will generate different armature fluxes at different positions in the air gap. As known from the analysis of the armature reaction of synchronous generators, under normal circumstances, the armature current can be decomposed into two hypothetical current components, namely the direct-axis current component Id=Issin⁡ΨI_d = I_s\sin\PsiId=IssinΨ and the quadrature-axis current component Iq=Iscos⁡ΨI_q = I_s\cos\PsiIq=IscosΨ. These two components respectively establish the magnetomotive forces FdF_dFd and FqF_qFq, and these two magnetomotive force components respectively generate the direct-ax...

First, let's understand what a diesel generator cylinder is. The cylinder is where the air - fuel mixture burns and performs work. Inside the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the high - pressure atomized diesel sprayed from the fuel injector. Under the compression of the upward - moving piston, the volume decreases, the temperature rises rapidly, and reaches the ignition point of diesel. The diesel is ignited, the mixture burns violently, the volume expands rapidly, and pushes the piston downward, which is called "doing work". The working environment of the cylinders in a diesel generator set is extremely harsh. Specifically, it has the following characteristics: 1.The inner surface is directly exposed to the action of high - temperature and high - pressure combustion gases. 2.There are drastic temperature changes during the working process. During the combustion process, the temperature of the combustion gas can reac...

Since diesel generators use diesel engines as power to convert diesel into electricity, they generate a great deal of noise during operation.

Diesel generators can be used as the main power source in places that are not powered by a power grid or as a backup in case of a power outage. They are not only suitable for large establishments but also for homes and small offices. However, there’s a common idea that diesel-powered generators are noisy. How to ensure that it stays at a reasonable sound level? In this article, we will share some effective solutions to reduce the diesel generator noise. The noise generated by diesel generators primarily stems from two sources. One is mechanical noise produced by the diesel engine during high-speed operation, typically caused by friction and vibrations among internal components. The other one is airflow noise generated during the cooling process as air enters and exits the generator unit. To effectively reduce these noises, comprehensive optimization in design and material selection is essential. Design of Air Intake, Exhaust Ports, and Channels The air intake, exhaust ports, and t...

Spark plugs, commonly known as spark igniters, are used to discharge the pulsed high-voltage electricity sent by high-voltage wires (spark plug wires). They break down the air between the two electrodes of the spark plug, generating an electric spark to ignite the air-fuel mixture in the cylinder. The main types include: standard spark plugs, insulator projection spark plugs, electrode spark plugs, seat spark plugs, multi-electrode spark plugs, surface discharge spark plugs, etc. Spark plugs work in conjunction with the ignition system and the fuel supply system to make the engine run, and to a large extent, jointly determine the performance of the engine. How much do you know about the maintenance of spark plugs for 200KW natural gas generator sets? For 200KW natural gas generator sets, the spark plugs should be maintained every approximately 250 hours of operation.

While a diesel generator is operating under load, it is also a process in which the components of the diesel generator itself wear against each other. Dingbo Power, a diesel generator set manufacturer, advises users to minimize the wear between the components of the generator set. In fact, reducing component wear is also a way to extend the lifespan of the generator set. So, in what aspects should our users pay close attention to prevent excessive wear of diesel generator components? The specific content is analyzed as follows: The quality of the fuel and lubricating oil for diesel generator sets should be compatible. If the diesel contains sulfur or other impurities, acids and other corrosive substances will be produced during the combustion process, accelerating the wear of the cylinder. If there are too many heavy fractions in the diesel, carbon deposits are likely to form after combustion, causing abrasive wear between the piston rings and the cylinder. The viscosity of diesel ha...
