有一台小四轮拖拉机,因柴油机固定螺栓松动,油底壳与机架加强筋碰擦而开裂,机油大量漏出未被发现,造成烧瓦事故。机油泄漏,压力肯定下降,驾驶员为什么没发觉呢?原来这台小四轮拖拉机配装的S195柴油机用的机油压力指示阀安装在机车前方,被水箱、机罩等挡住,驾驶员开车时看不见。而且,有时指示阀堵塞了,也反映不了油压情况。我们在机罩表盘上装一个油压表,驾驶员可以随时观察油压情况,可以避免上述事故。做法是:在机罩仪表盘上钻孔,安装一个0～0.686兆帕(0～7公斤力/厘米~2)的压力表;将原机油
A small four-wheel tractor, due to loose diesel engine bolts, oil pan and frame stiffeners rub and crack, a large number of oil leakage has not been found, resulting in burning tile accident. Oil leakage, the pressure must decline, why the driver did not find it? The original small four-wheel tractor equipped with S195 diesel engine oil pressure indicator valve installed in front of the locomotive, was blocked by the water tank, hood and other drivers to see not see. Moreover, sometimes the indicator valve is blocked, but also can not reflect the hydraulic conditions. We have a hydraulic gauge on the hood dial, the driver can observe the hydraulic conditions at any time, to avoid the above accidents. Practice is: Drill holes in the hood dashboard, install a 0 ~ 0.686 MPa (0 ~ 7 kg force / cm ~ 2) pressure gauge; the original oil
