Diesel Generator Tech

What do you think is the reason for the low backup power supply voltage of Cummins diesel generator sets? The application of Cummins diesel generator sets has brought convenience to people's lives, but there are still some problems in use. Below, the editor will share with you the reason for the low backup power supply voltage of   Cummins diesel generator sets , including the low speed of the prime mover. The process is to adjust the speed of the prime mover to the rated value. If the resistance of the excitation circuit is too high, the treatment will reduce the resistance of the field rheostat to increase the excitation current. For semiconductor excitation diesel generator sets, it is necessary to check whether the additional winding joints are disconnected or connected incorrectly. The exciter brush is not in the neutral position, which may cause handling issues or low spring pressure. Adjust the brush to the correct position, replace the brush, and adjust the spring pressure....

How to regularly check the wear of the keyways and fixing bolts related to diesel generator sets, using standard high-pressure oil pipes. During the fuel supply process of the fuel injection pump, due to the compressibility of diesel and the elasticity of the high-pressure fuel pipe, high-pressure diesel will form pressure fluctuations inside the pipe. The transmission of pressure waves inside the pipe requires a certain amount of time. To ensure consistent fuel supply interval angle, uniform fuel supply, and stable operation of the   diesel generator set , the length and diameter of the high-pressure fuel pipe are selected through calculation. Therefore, when the high-pressure oil pipe of a certain cylinder is damaged, a standard length and pipe diameter oil pipe should be replaced. In practical use, due to the lack of standard oil pipes and the use of other oil pipes instead, regardless of whether the length and diameter of the oil pipes are the same, there is a significant diffe...

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 ...

In a humid environment, the insulation performance of diesel generator set and electrical components will be reduced due to moisture, and metal parts will be corroded, which will cause accidents in serious cases. Therefore, careful maintenance must be carried out. In this article, Starlight Power will share the maintenance methods of two  diesel generator sets  in humid environment. (1) Frequently pay attention to the insulation performance of the electrical components and circuits of the unit. When there is a fault, the insulation monitoring indicator light will light up, and the cause should be carefully checked and eliminated. If it drops due to moisture, the motor winding needs to be baked to restore its insulation performance. Usually, external heating method or current passing method inside the coil are used to evaporate the moisture in the motor winding; Or start the unit and adopt a gradual loading method to gradually increase the current inside the motor and driv...

Starlight Power provides free after-sales service tracking and follow-up visits to Guangxi Baijiahua Department Store Co., Ltd., which has purchased our company's   600kw Ricardo generator . The follow-up personnel conducted a series of inspections and maintenance on the unit, and no abnormalities were found. The unit is operating normally, and the voltage and electricity meters are also normal. Since the unit has been in operation for 8 years, our after-sales personnel suggest that Guangxi Baijiahua Department Store Co., Ltd. rectify the generator components by replacing the engine oil, oil filter element, diesel filter element, air filter element, and water tank.   Jiangsu Starlight Power Generation Equipment Co., Ltd. was founded in 1974 and is one of the earliest manufacturers of generators and  diesel generator sets  in China. The company has a registered capital of 218.88 million yuan. The company covers an area of 86,000 square meters and a building area of 55...
