Diesel Generator Tech

 What should we do if the new diesel generator is overhauled without running-in? After the new diesel generator has been overhauled, the cylinder liner, piston, piston ring, and bearing bushes have been replaced. It has not been fully run-in and loaded with load, causing early wear and tear of the parts. And some also show the phenomenon of cylinder pulling and tile burning. After the diesel generator is cold-started, the oil viscosity is high and the flow resistance is also large, which makes the time lag for the oil to enter the friction pair, and all parts of the diesel engine are not fully lubricated, causing the gears and bearings of the diesel analyzer to be damaged due to poor lubrication , but also aggravated the wear of the cylinder and the bearing bush. Especially supercharged diesel generators will cause ablation of the turbocharger's shaft. For this reason, the supercharged diesel generators should be idling for a while after starting, the standby oil tem...

 Why do diesel generator sets burn tiles during operation? Diesel generator set burning tile is a serious unit failure. Once the tile is burned, it will seriously hinder the operation of the diesel generator set. The burning of tiles in diesel generator sets is inseparable from the following six reasons. First, the use of lubricating oil does not correspond to the season. In different seasons, the corresponding lubricating oil should be used. For example, in summer, the lubricating oil with higher viscosity should be used so that an oil film can be formed on the contact surface of the bearing bush. If there is a disorder, it will cause the failure of the diesel generator set. Impurities are mixed in the lubricating oil. If you do not pay attention to the cleaning of the lubricating oil and directly inject the lubricating oil into the machine, the oil circuit will be blocked, which will lead to burning of the tiles. Without paying attention to the oil pressure gauge, by...

 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...

  Since January this year, the southern region has suffered from continuous rainy weather. Improper handling of diesel generator sets during use is prone to moisture problems, especially the damping of the motors of the generator sets, which has a great impact on the life and work of the generator sets. At this time, the user must dry the damp diesel generator set . For the relevant drying method, the user can refer to the following methods: 1. Short-circuit the three-phase outlet of the stator winding and connect it firmly. 2. Adjust the resistance of the voltage regulating rheostat in the excitation circuit to the maximum value. If the resistance value is not enough, add another resistance to increase the resistance value. 3. Start the generator set , slowly increase it to the rated speed, and then slowly adjust the excitation current. The excitation current is determined according to the damp condition of the generator set, and the short-circuit current of the stator ...

As a user, I believe that when you purchase a diesel generator set, the generator manufacturer must have emphasized to you that you need to maintain the diesel generator set regularly, so you know why it is very important to maintain the diesel generator set regularly. Is it important? In this article, Jiangsu Starlight Electricity Equipments Co.,Ltd. will tell you the reasons for this from the engine oil. Most people don't know that engine oil can degrade over time even when the engine is not running at all. If the life expectancy is 1 year, it doesn't mean it can maintain 100% quality in a year. It started to degenerate from day one, but still reached acceptable tolerance levels after a year. Now, if you extend your service interval to 18 months, that doesn't mean your oil is half as good as new, because you've exceeded the recommended 50% change. Oil does not degrade linearly, which means it may retain its usefulness and then suddenly lose 90% of its l...
