拖拉机在田间工作时,和空气一同被吸入的灰尘对发动机的么损有很大的影响。灰尘进入拖拉机发动机,粘附在汽缸壁上或落入曲轴室滑油内,这不仅加速汽缸活塞组的么损,而且也加速其他零件的么损。结果,发动机修理间隔期与固定工作时没有灰尘的发动机相此较就缩短好几倍。国营农场机机化电气化科学研究所拖拉机利用实验室的观察表明,甚至细心地遵守空气滤清器的全部保养规则时,在ДT—54拖拉机的空气滤清器的集尘器内和吸气管内,发现有尘土的乾渣,在C—80拖拉机上发现油泥。同时在一些长久耕耘于休闲地的拖拉机上,发现活塞组和缸套有急剧磨损的情况。这就说明,现有拖拉机的滤清器不能完全 When the tractor is working in the field, the dust sucked in with the air has a great impact on the damage of the engine. Dust enters the tractor engine, adheres to the cylinder walls or falls into the crankcase oil, which accelerates damage not only to the cylinder piston assembly but also to other components. As a result, engine repair intervals are several times shorter than those for engines that are dust-free during regular operation. Observations from the Tractor Utilization Laboratory at the National Institute of Agricultural Mechanization and Electrification Institute show that even with careful care of all the maintenance rules of the air filter in the dust collector of the air cleaner of the ДT-54 tractor and in the suction pipe , Found the dust of the dry residue, found in the C-80 tractor sludge. At the same time in some long-time hard work in the tractor, found that the piston set and cylinder liner with a sharp wear and tear. This shows that the existing tractor filter can not be complete
