Things to be aware of when replacing diesel generator sets

After the diesel generator set is used for a period of time, some parts will inevitably need to be replaced, and a series of problems such as assembly errors will inevitably occur during the replacement, which greatly affects the use of the diesel generator set. I hope everyone will pay more attention to the following points.

1. Diesel generator set replacement parts must be cleaned. If the machine is mixed with mechanical impurities, dust and sludge inside the assembly, it will not only accelerate the wear of the parts, but also easily lead to oil blockage and accidents such as burning the shaft and holding the shaft. Therefore, when repairing and assembling diesel engine parts, pay attention to ensure the cleanliness of parts.

2. Different enlarged parts (accessories) of the same model are not universal. When using the repair size method, you can use oversized parts, but you must be sure which part of the part is enlarged. If the size of the parts is not mastered during the repair of the diesel generator replacement parts, then this will not only waste time, but also can not guarantee the quality of the repair, and will greatly reduce the service life of the bearing bush. In severe cases, the generator set will be scrapped as a whole.

3, diesel generator replacement parts repair assembly technical requirements. The repair personnel generally pay more attention to the valve clearance and bearing clearance of the generator, but some technical requirements are often neglected. For example, when installing the cylinder liner of the generator set, the upper plane should be higher than the plane of the body by about 0.1mm, otherwise it will A cylinder leak occurs or the cylinder head is continuously damaged.

4. Replacement of diesel generator sets. Note that some fittings must be replaced in pairs. For example, the injector needle valve coupler, the plunger pair and the oil discharge valve pair must be replaced in pairs, which can generally be done. However, some other accessories are not paid attention to in pairs. For example, when replacing the gears, only one of the more severe wears is replaced. After the assembly, the meshing is not good, the noise is increased, the wear is intensified, and the service life is greatly shortened. Therefore, the diesel engine is replaced. When repairing, it should be noted that some fittings should be replaced in pairs to ensure the quality of the repair. It is not necessary to replace the parts in order to save costs. When the time comes, the entire generator set is completely damaged.

5. Prevent the parts from being misplaced or missing when the diesel generator is replaced. In the case of a single-cylinder diesel engine, there are more than a thousand parts, and most of them have certain installation position and orientation requirements. If you do not pay attention, it is easy to misfit or miss. If there is a misassembly or a missing installation, it may cause the engine to start difficult or not start at all.

In summary, when replacing parts for diesel generator sets, attention should be paid to the cleaning of parts, the matching of components, and the technical requirements of assembly. In particular, attention should be paid to the misassembly and missing of parts. I hope that you will strictly abide by the strict points of work in the repair and replacement of the parts, otherwise it will affect the normal use of the unit, and in serious cases will cause the unit to be scrapped, causing no small losses to the enterprise.
