冬季气温低,当气温降至润滑油凝固点时,拖拉机传动件的转动阻力将增加十几倍。如果拖拉机在这种情况下强行启动,就会使曲轴扭曲变形,飞轮齿圈及各转动件损坏。那么,在寒冷的冬季,应怎样安全启动拖拉机呢?1.拖拉机要先预温后启动。拖拉机停车熄火后,趁热放出油底壳内的机油,次日启动前用炭火或热水加温,严禁用明火直接烤油底壳,防止烧毁机车和机油遇高温而老化变质。2.当气温在-5~0℃时,向机体内加热
Winter low temperatures, when the temperature dropped to freezing point of oil, the tractor transmission will increase the rotation resistance ten times. If the tractor is forcibly started in this condition, it will distort the crankshaft and damage the flywheel ring gear and each rotating member. So, in the cold winter, how should safely start the tractor it? 1. The tractor must warm up after the start. Tractor parking flameout, hot oil released from the oil pan, with charcoal or hot water before the start of the next day heating, non-direct fire with oil pan is prohibited to prevent burned locomotives and oil met the heat and aging deterioration. 2. When the temperature is -5 ~ 0 ℃, heat the body
