柴油机由千百个零件组成。在柴油机零部件被拆散后,应该按顺序放置好,并且做好记号,然后对各零件进行仔细的清洗和鉴定。对于不需要修理和更换的零件,必须按原位装复。这是由于柴油机经过一段时间工作后,各部位零件已经磨合贴切,再加上各气缸、各部位零件的磨损量的不均匀,为了获得良好的配合关系,所以应该“对号入座”,按原位装配。如果将解体后的零件杂乱无章地堆放在一起,装复后将破坏柴油机正常的工作性能。 那么,柴油机哪些零件必须按原位装配呢? 1.柱塞副、出油阀、喷油嘴。这3对偶件的配合非常精密,例如喷油泵柱塞与柱塞套的配合间隙仅0.001～0.003毫米,而且它们之间经过
Diesel engine consists of hundreds of parts. After the diesel engine parts have been disassembled, they should be placed in order, with good marks, and then the parts should be carefully cleaned and evaluated. Parts that do not need to be repaired and replaced must be refitted in place. This is due to the diesel engine after a period of work, the various parts of the parts have been running fit, coupled with the cylinder, the parts of the wear and tear of the uneven, in order to obtain a good relationship, it should be “condemnation”, according to the original assembly . If you disassemble the parts messy stacked together, will be destroyed after the installation of diesel engine normal working performance. So, what parts of the diesel engine must be assembled in place? 1. Plunger, the valve, nozzle. The mating of these three couples is very precise. For example, the clearance between the injection plunger and the plunger sleeve is only 0.001 to 0.003 mm, and the clearance between them
