Diesel Generator Tech

If the fuel supply of each cylinder of Cummins diesel generator is uneven, it will directly affect the stability of the engine. You can remove the fuel injection pump and check and adjust it on the test bench. However, if there is no test bench for diesel generator and you need to check the uneven fuel supply, you can also roughly check the fuel supply of the suspected cylinder, and check and adjust the method:  1. Prepare two glass measuring cylinders for use. If you cannot find the measuring cylinder at the moment, you can also use two identical small bottles instead. 2. Remove the high-pressure fuel pipe connector that connects the first cylinder with an excessive (or insufficient) fuel supply to the fuel injector. 3. Remove the high-pressure pipe joint connecting the normal fuel supply cylinder and the fuel injector.  4. Insert the two fuel pipe ends into two measuring cylinders (or vials) respectively.  5. Rotate the engine with the star...

Silent generator sets are widely used in places with strict environmental noise requirements, such as post and telecommunications, hotels and buildings, entertainment venues, hospitals, shopping malls, industrial and mining enterprises, etc. They are used as regular or backup power sources. When purchasing and installing silent generator sets, it is necessary to comprehensively consider the possible impacts of various complex climates on the generator sets to ensure their normal operation. The use of silent generator sets is greatly affected by the surrounding environment. When the environmental climate changes, silent generator sets will also change accordingly. Therefore, when installing silent diesel generator sets, the impact of the climate environment must be taken into account.

  Diesel three-phase generator usually refers to the electromagnetic device driven by the prime mover to generate current, leading to three fire wires so as to achieve a higher voltage power. If you encounter a failure can not work properly, it is likely because the generator line or magnetic circuit is damaged, today Dingbo Power will introduce you about what are the reasons why the   diesel three-phase generator sets   do not generate electricity .   1. Diesel three-phase generator does not run according to the limited technical conditions, such as high stator voltage, load current is too large, stator winding copper loss increases.   2. The frequency is too low, so that the cooling fan speed slows down, affecting the generator heat dissipation, the power factor is too low, so that the rotor excitation current increases, affecting the rotor heat.   3. It is necessary to check whether the indication of the monitoring inst...

Corona is a type of partial discharge in generators, which occurs on the surface of insulation and is different from the corona near conductors under general outdoor high-voltage electric fields. It refers to the glow discharge caused by uneven electric field distribution and excessive local field strength on certain parts of the insulation surface of the high-voltage winding of the   generator stator , which leads to ionization of nearby air. So where are the locations where generators are prone to corona discharge? Today, Dingbo Electric will provide a detailed explanation for everyone. 1. End band wrapping area.   2. At the slot of the wire rod. The winding slot is a typical sleeve type structure, and the slot electric field is very concentrated, making it the most prone to corona discharge.   3. Between the end opposite phase wire rods. The distribution of electric field at the end of the winding is complex, especially at the contact parts and edges between the coil a...

Summer weather is hot, there are many thunderstorms, and diesel generators are often used outdoors, so it is a common phenomenon for diesel generator sets to be drenched by rain. After the diesel generator was rained out, many users are most worried about the question of whether the diesel generator after being rained out affects power generation. Today Dingbo Power answer this question for you. This is divided into two cases, one case is the diesel generator set did not enter the water, this is relatively simple, only need to use water to rinse off the diesel generator set appearance of dust and impurities. Another situation is the diesel generator set into the water, this situation is slightly more complex, there are the following ways to deal with: 1. Rinse the exterior of the diesel engine with water to remove soil and debris, and then use a metal cleaner or laundry detergent to remove oil from the surface. 2. Support one end of the diesel engine so that the oil pan drain area is a...

In a diesel generator, the piston ring groove is surrounded by a certain elastic metal open ring. This metal ring is called the piston ring. Piston ring is one of the key components of the diesel generator, its performance directly affects the quality and reliability of the diesel generator. According to the different uses of piston rings, piston rings are categorized into gas rings and oil rings. The main role of the gas rings is to form a sealed combustion chamber space with the piston, cylinder head and cylinder liner to prevent the high temperature and high pressure gases in the combustion chamber from flowing into the crankcase from the piston gap, as well as the cylinder wall. The main role of the oil ring is to ensure that the oil is evenly distributed on the inner wall of the cylinder liner, preventing the oil from entering the combustion chamber. If the oil enters the combustion chamber, the diesel generator will burn the oil, and blue smoke will come out of the exhaust pipe, ...

 Mechanical equipment is inevitably prone to wear and tear after a period of use, and Yuchai diesel generator sets are no exception. But if it is excessive wear or abnormal wear, such a situation is abnormal and must be taken seriously. Generally, it is due to improper use by the user or machine failure. Therefore, it is necessary to understand the reasons that cause the wear of the diesel generator set in order to take targeted measures to avoid excessive wear and shorten the service life of the diesel generator set. The wear of 600KW diesel generator sets such as Yuchai generator set, Cummins diesel generator set, and Shangchai generator set is generally affected by the quality of fuel and lubricating oil, the operating speed and load of the diesel engine, environmental conditions, and operating conditions. The quality of fuel and lubricating oil should be compatible with the structure of the diesel generator set. If diesel contains sulfur or other impurities, acids and other cor...

What is the compression ratio of a diesel engine? Regardless of whether the equipment is equipped with a gasoline or diesel engine, maintaining a stable and appropriate compression ratio is essential to ensure smooth and stable operation of the diesel engine. The compression ratio of a general diesel engine is immutable, as the combustion chamber volume and cylinder working volume are fixed parameters that have been determined in the design. So what will be the impact of a decrease in compression ratio for diesel generators? The compression ratio is the ratio of the total cylinder volume of a diesel generator set to the combustion chamber volume. Its variation not only affects the power and economy of the generator set, but also affects its starting performance. In the design, each diesel generator set is specified with a compression ratio, but in use, due to various related factors, its compression ratio often decreases.  1.The position of the piston at the end of compression is l...
