Diesel Generator Tech

What are the measures to prevent cylinder gasket burning of Volvo diesel generators? Firstly, improve the maintenance and assembly quality of Volvo diesel generators. Poor repair quality of Volvo diesel generators is the main factor causing cylinder gasket burning. When repairing   Volvo diesel generators   for this purpose, the following points should be taken into account: firstly, the cylinder sleeve should be correctly assembled. Before the cylinder sleeve is inserted into the cylinder, the external surface of the cylinder sleeve, the upper and lower parts of the cylinder block seat holes to the bearing shoulder should be thoroughly cleaned of dirt and rust, and the trial fitting work between the cylinder sleeve and the cylinder block seat holes should be done well. During trial assembly (without installing a water stop ring), the cylinder liner should rotate flexibly in the cylinder block seat hole without jamming, and there should be no obvious gap feeling during radial ...

Have you ever thought about the reasons for thermal runaway of diesel generator sets? The application of diesel generator sets involves an extremely wide range, and occasional thermal runaway phenomena are unavoidable. When a fault occurs, it is necessary to calmly analyze the cause of the fault and find a solution. Thermal runaway refers to the phenomenon where the floating charge current and temperature of a battery undergo an accumulation of mutual growth during constant voltage charging, resulting in damage to the battery due to excessive temperature. When this phenomenon occurs, it may be a precursor to internal problems in the equipment. Therefore, we need to accurately determine the cause of thermal runaway of the   diesel generator set , and then confirm the faulty components. Firstly, it is possible that the float charging voltage is too high. Setting the float charging voltage too high will increase the float charging current and cause the battery temperature to rise. Sec...

The staff of diesel generator set manufacturers are gradually sorting out the fault performance of different brand and model equipment such as Cummins diesel generator set,   Volvo diesel generator set , and silent diesel generator set. In this process, some abnormal sounds caused by diesel generator set faults are the focus of research. Next, let's briefly talk about one of the abnormal noises. Abnormal noise at the piston ring of diesel generator set: The abnormal noise at the piston ring mainly includes the metal tapping sound of the piston ring, the leakage sound of the piston ring, and the abnormal noise caused by excessive carbon accumulation. (1) The metal tapping sound of the piston ring. After long-term operation of the diesel generator set engine, the cylinder wall is worn out, but the upper part of the cylinder wall that is not in contact with the piston ring almost maintains its original geometric shape and size, which creates a step on the cylinder wall. If an old cyli...

In the troubleshooting of diesel generator sets, Dingbo power generation equipment has mentioned that abnormal smoke or the color of smoke that does not conform to common sense is a symptom of the fault. In addition, some abnormal steam emission is also a warning for the fault. Diesel generator sets  may encounter steam from the refueling port due to factors such as oil quality and environmental temperature difference. How should we troubleshoot this issue? Next, the technical personnel from the diesel generator manufacturer will briefly explain to you based on their experience: 1. After starting the diesel engine, observe the exhaust smoke situation of the exhaust pipe. After 5 minutes, the exhaust smoke turns light gray, and a small amount of white vapor emerges at the fuel filler, which is within the normal range. 2. Check the oil quality of the engine oil to see if there is any deterioration. 3. After stopping the machine, disassemble the fuel injector and conduct an oil pressu...

The generator is a mechanical equipment that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or atomic Nuclear fission into mechanical energy and then transfers it to the generator, which converts it into electrical energy. Generators have a wide range of applications in industrial and agricultural production, national defense, technology, and daily life. The so-called phase leading operation of   generators   refers to the stable operating state of generators emitting active power and absorbing reactive power. When the generator is running in phase, four main issues should be noted: First is a decrease in static stability. The second is that the end leakage magnetic field causes an increase in the temperature of the stator end. Thirdly, the voltage of auxiliary power decreases. Fourthly, due to the decrease i...

Due to its small size, convenient handling, fast power supply, long service life and simple operation, diesel generator sets have been used in various fields, such as standby power supply in factories, fire emergency power supply in real estate, and supplementary power supply in construction site. In order to improve work efficiency and ensure safe production, Dingbo Power will talk with you about what we should pay attention to when using   diesel generator sets   in the construction site. The specific content is as follows: When the diesel generator set is under construction on the construction site, Dingbo Power reminds the user of the following matters: 1. During site construction, the rated voltage of the diesel generator set must be consistent with the power supply voltage, frequency and other parameters of the electrical equipment used. 2. The installation environment of the diesel generator set on the construction site shall be close to the load center, with conve...

When the ground fault occurs to the generator in the diesel generator set configuration, it is characterized by loud noise, irregular jitter, temperature rise, unstable voltage, and similar excessive load. This fault is a ground fault caused by insulation damage between the generator winding and the iron core or the casing, also known as a winding ground fault. So, how should our users troubleshoot generator grounding faults? Here, Dingbo Power will share the following content with everyone for learning and reference in   genset maintenance . Ground fault phenomenon The diesel generator set can not operate normally due to the electrification of the generator housing, control line out of control, and winding short circuit heating. Cause of malfunction Due to dampness in the generator winding, the insulation resistance decreases; Long term overload operation of the generator; Harmful gas corrosion; Metal foreign objects invading the inside of the winding damage the insulation; Insula...
