东风—5型联合收割机在作业中往往因其机油温度过高而影响作业效率,甚至造成烧瓦等事故。几年来为了解决机油温度过高的故障,采取了多种办法。如:增设风扇和机油散热器或将原单级机油过滤器或换成东方红54/75拖拉机的双级机油过滤器等,都收到一定的效果。但这些改装有的结构复杂;有的对降低机油温度的幅度不大。为了彻底解决这一问题,海伦农场机务科和该场十二队康拜因手、场劳动模范莫井来同志一起研究出在东风—5型 Dongfeng -5 combine harvester in the operation often because of its oil temperature is too high and affect the operating efficiency, and even cause accidents such as burning tiles. Over the past few years in order to solve the oil temperature is too high fault, take a variety of ways. Such as: additional fan and oil radiator or the original single-stage oil filter or replaced by the East Red 54/75 tractor double-stage oil filter, etc., have received some results. However, some of these modified complex structure; some to reduce the temperature of the oil is not the magnitude. In order to completely solve this problem, Helen Farm Machinery Branch and the field team Kang Bain 12 hand, field labor model Comrade Mo Jing to study together in Dongfeng -5
