Diesel Generator Tech

 What problems should be paid attention to when replacing parts of Cummins diesel generator set? First of all, pay attention to the assembly technical requirements for replacement and repair of Cummins diesel generator. Repairers generally pay more attention to the valve clearance and bearing clearance of diesel generators, but some technical requirements are often ignored. For example, when installing the cylinder liner of a diesel generator set, the upper plane should be about 0.1mm higher than the plane of the body, otherwise The failure of cylinder air leakage or continuous damage to the cylinder head gasket will occur. Different enlarged parts (accessories) of the same model are not universal. When using the repair size method, you can choose to increase the size of the parts, but you must find out which level of increase is the part. If the size of the parts is not mastered when the diesel generator is replaced and repaired, it will not only waste time, but also...

 Cummins diesel generators will generate a lot of heat during operation. If ventilation and heat dissipation are not done properly, the generator set may be damaged or even cause major equipment failures. Therefore, users must pay attention to the ventilation and heat dissipation problems of the unit during installation. Specific requirements are as follows: 1. When installing the Cummins diesel generator set , the radiator should be as close to the air outlet as possible to avoid the recirculation of hot air. When there is no air duct, it is recommended that the distance between the radiator and the air outlet should not exceed 150 mm. If the equipment room cannot meet the above requirements, the corresponding air duct should be installed. 2. The area of the exhaust port should be 1.5 times the exhaust area of the radiator. Under normal circumstances, it is necessary to cooperate with the radiator to install the air duct and the exhaust shutter. The bend of the ...

 The idle state is the idling working state of the diesel generator set, that is to say, in this management working environment state, the diesel generator set does not need to carry the load, as long as we maintain the minimum speed required during the smooth operation.   The idle time of the diesel generator set should not be too long, and the diesel injection will reduce the atomization quality and accelerate the early wear of the cylinder wall. Because the quality of the atomization technology is mainly related to the injection pressure of the diesel generator set, the diameter of the injector and the speed of the camshaft. Since the aperture size of different injectors remains unchanged, the quality of fuel atomization technology depends on the injection pressure and camshaft speed. The slower the camshaft speed is, the longer the fuel injection pressure will continue to rise, the worse the quality of the fuel through the atomization technology, and the cams...
