一、机油压力不稳,换一颗钢球就行有一台丰收-35型拖拉机的机油压力很不稳定,反映在机油压力表上就是:表的指针时而指向4公斤力/厘米~2,时而指向0.4公斤力/厘米~2,机油压力变化幅度高达3.5公斤力/厘米~2。一般当机油压力的变化幅度大时,通过调节机油压力调节阀即可奏效,这次任你怎样调节机油压力调节阀,都无济于事。后来,我们把机油压力调节阀拆开进行检查,发现调节阀钢球 First, the oil pressure instability, change a ball on the line there is a bumper harvest -35 tractor oil pressure is very unstable, is reflected in the oil pressure gauge is: the table pointer sometimes point to 4 kg / cm ~ 2, sometimes pointing 0.4 kg force / cm ~ 2, the oil pressure changes up to 3.5 kg force / cm ~ 2. Generally, when the variation range of the oil pressure is large, it can not be achieved by adjusting the oil pressure regulating valve by adjusting the oil pressure regulating valve. Later, we opened the oil pressure regulating valve to check and found that regulating valve steel ball
