冬春寒冷季节,为了防止冻裂机体,要在发动机冷却系统内加注防冻液。目前常用的防冻液有乙醇、乙二醇、甘油和甘油-乙醇等,这些防冻液由于配制比例、成分不同,其凝点也有所不同,今天就为大家介绍一下农机防冻液如何使用。1加注防冻液前,应先清除冷却系统的水垢,并放净残水以免冲淡防冻液,降低防冻液的结冰凝点。2加注防冻液时,只能加到冷却系统容量的93%~95%。防冻液具有吸湿性,冷却系统应密封好。
Winter and cold In the cold season, in order to prevent the fissure body, add antifreeze into the engine cooling system. The commonly used antifreeze are ethanol, ethylene glycol, glycerol and glycerol - ethanol, these antifreeze due to the preparation of the proportion of different components, the freezing point is also different, today for everyone to introduce agricultural antifreeze how to use. 1 Before filling antifreeze, the scale of the cooling system should be removed first, and the residual water should be drained to avoid diluting the antifreeze and freezing freezing point of the antifreeze. 2 When adding antifreeze, it can only be added to 93% ~ 95% of the cooling system capacity. Antifreeze has hygroscopicity, cooling system should be sealed.
