黄油是一种很好的润滑剂,多用于低速、重负荷、油料容易流失的部位。拖拉机上少不了它。但是,黄油可不能乱抹,抹错了地方会出大事。例如,有的机手在安装调速器的调速滑盘时,为了防止钢球掉下,在调速支架的径向槽内抹上黄油,把钢球粘住。钢球被粘住,在发动机转速发生变化时就不能在支架内灵活移动,及时调整供油量。轻者使发动机转速不稳,出现游车,重者会造成飞车或熄火,危害极大。 Butter is a good lubricant, used for low-speed, heavy-duty, easy to drain parts of the oil. The tractor can not stop it. However, the butter can not be rubbed, the wrong place will be a major event. For example, some hands in the installation of governor speed governing disk, in order to prevent the fall of the ball, the governor bracket radial grooved butter, the steel ball stick. Steel balls are stuck, the engine speed changes can not be flexible in the stent movement, timely adjustment of fuel supply. The light of the engine speed instability, there are cars, heavy vehicles will cause speeding or flameout, endangering great.
