After the use of diesel generator set for a period of time, some parts will inevitably wear and need to be replaced, and a series of problems such as assembly errors will inevitably occur during replacement, which greatly affects the use of diesel generator set. I hope you will pay attention to the following points.
1, diesel generator replacement repair assembly must pay attention to clean. If there are mechanical impurities and dust and mud mixed in the body during assembly, it will not only accelerate the wear of parts, but also easily cause oil circuit blockage, resulting in accidents such as burning tile and holding shaft. Therefore, in the diesel engine replacement parts repair assembly should pay attention to ensure the cleanliness of the parts.
2, the same model of different large parts (accessories) are not common. When using the repair size method, you can choose to increase the size of the parts, but you must identify which level of the parts to increase. If the size of the parts is not mastered when the diesel generator is replaced and repaired, then this not only wastes time, but also cannot guarantee the repair quality, and will greatly reduce the service life of the bearing, and the whole generator set is scrapped when it is serious.
3, diesel generator replacement repair pay attention to the assembly technical requirements. The repair personnel generally pay more attention to the valve clearance of the generator, the bearing gap, etc., but some technical requirements are often ignored, such as the installation of the cylinder liner of the generator set, the upper plane should be about 0.1mm higher than the body plane, otherwise there will be cylinder leakage or continuous washout of the cylinder gasket.
4, diesel generator replacement parts repair attention to some matching parts to be replaced in pairs. For example, the injector needle valve pair, the plunger pair and the oil valve pair are three precision pairs to be replaced, which can generally be done. However, some other accessories do not pay attention to replacement in pairs, such as replacing the gear, only replace the one with more serious wear, due to poor meshing after assembly, noise increases, wear intensifies, the service life will be greatly shortened, so pay attention to some matching parts to be replaced in pairs when replacing diesel engine parts. In order to ensure the quality of maintenance, it is important not to choose a single replacement in order to save costs, when the whole generator set is completely damaged.
5, diesel generator replacement parts repair to prevent parts misinstallation, leakage. As far as single-cylinder diesel engines are concerned, there are more than one thousand parts, and most of them have certain installation position and direction requirements, if you do not pay attention, it is easy to misinstall or leak. If there is wrong installation, missing installation and other situations, it will cause the engine to start difficult or can not start at all.
In summary, when replacing parts for diesel generator sets, it is necessary to pay attention to the cleaning of parts, the allocation of accessories, and the assembly technical requirements, especially the wrong installation and missing installation of parts. I hope that you will work with a rigorous attitude and strictly abide by the main points of each link when changing parts and repairing, otherwise it will affect the normal use of the unit, and in serious cases it will lead to the scrapping of the unit, which will bring no small loss to the enterprise.
