一、柴油机的使用 1.新购买的耕整机在开始使用前,柴油机为什么要经过磨合,怎样磨合? 柴油机是耕整机的主要动力,新的或大修后的柴油机在开始使用之前,一定要经过磨合。因为柴油机装配的零件,其配合表面虽然经过精加工,但仍然是不平的。如果柴油机不经磨合立即提高转速和带负荷作业,则各运动件的摩擦表面就会发生拉毛损伤。还会由于各粗糙表面的嵌合挤走润滑油,难于在接触表面形成润滑油膜,甚至会造成烧熔和卡住,导致运动件的早期磨损和损坏,柴油机的使用期限将大大缩短。柴油机的磨合就是指在人为的控制下,缓慢地提高转速、逐渐地增加负荷,在良好的润滑条件和认真检查下,使零件的配合表面逐渐磨平的过程。 (1)磨合前的准备(小型柴油机) ①清除柴油机外部零件上的灰尘和杂物。②仔细检查所有零件的完整性
First, the use of diesel engine 1. The newly purchased tillage machine before starting to use, why the diesel engine after running-in, how run-in? Diesel engine is the main driving force of the machine, the new or overhaul of the diesel engine before starting, be sure to After running in. Because of the diesel engine parts, although the mating surface with finishing, but still uneven. If the diesel engine does not run-in immediately to increase the speed and load operation, the friction surface of the moving parts will occur hair damage. But also due to the rough surface of the embedded squeeze away the lubricant, it is difficult to form a lubricant film on the contact surface, and even cause burning and stuck, leading to early wear and tear of moving parts, diesel service life will be greatly reduced. Diesel engine run-in refers to the artificial control, slowly increase speed, gradually increase the load, under good lubrication conditions and careful examination, so that parts with the surface gradually smoothing process. (1) Preparation before running-in (small diesel engine) ① Remove dust and debris from the external parts of the diesel engine. ② carefully check the integrity of all parts
