哪些原因造成了发电机组的“漏油”?

1置办或自制纸垫质量不合请求,如厚度不够,或保管不当,皱折变形,或装配时不留意清洁,沾有灰尘杂质,这些均是产生漏油的缘由。

1. Unqualified quality of paper cushions, such as insufficient thickness, improper storage, wrinkle deformation, or inadvertent cleaning and dust contamination during assembling, are the causes of oil leakage.

2机油压力过高,也惹起静接合面机油渗漏。

2. Excessive oil pressure also causes oil leakage of static joint surface.

3静接合面自身质量,它主要由加工设备自身的精度及储运条件决议。假如设备精度高,静接合面平面度、粗糙度均能到达图纸设计请求,且在储运过程中留意避免磕碰等,不难到达静接合面完整密封。但由于一些厂家设备精度和工艺程度还较低,储运条件和管理程度不能完整保证无磕碰划伤。

3. The quality of the static joint surface is mainly determined by the accuracy of the processing equipment itself and the storage and transportation conditions. If the equipment has high precision, the flatness and roughness of the static joint surface can reach the drawing design request, and pay attention to avoid bumping during storage and transportation, it is not difficult to reach the complete seal of the static joint surface. However, due to the low accuracy of equipment and technology of some manufacturers, the storage and transportation conditions and management level can not guarantee the complete non-knock scratch.

4维修颐养时操作技术欠佳。目前柴油发电机组普通以自修为主,由于修理技术程度跟不上,自修中常常呈现这样或那样问题,特别是拆装机器时不留意办法,短少专用工具,使零件产生变形,以至损坏。由于零件变形,惹起漏油。目前,普通拆卸办法用主轴承座盖装置螺栓,拧进主轴承座盖上对角拆装螺孔内,顶出主轴承座盖。在拆装过程中很难做到两个螺栓进度同步,这是形成主轴承座盖变形的主要缘由。

4. Poor operation skills in maintenance and maintenance. At present, diesel generating units are mainly self-repairing. Because the repair technology is not up to date, self-repairing often presents such or such problems, especially when disassembling and assembling machines, they do not pay attention to methods, and there are few special tools, which cause parts to be deformed and even damaged. Oil leakage is caused by deformation of parts. At present, the common disassembly method is to install bolts on the main bearing seat cover, screw them into the diagonal disassembly screw hole of the main bearing seat cover, and eject the main bearing seat cover. It is difficult to synchronize the progress of the two bolts in the process of disassembly and assembly, which is the main reason for the deformation of the main bearing seat cover.
