为防止燃油稀释机油,诺伊施特雷利茨机务段的一个革新小组建议,将喷油泵吸油室的压力从25牛顿/厘米~2(≈2.5公斤/厘米~2)降低到6～8牛顿/厘米~2。如果照此办理,喷油泵柱塞偶件的漏油量将大大下降,也不会由于过早达到粘度下限72厘斯而必须更换柴油机机油。当然,在改变喷油泵吸油室压力之前,有必要进行深入的研究,搞清楚喷油泵吸油室压力与漏油量之间的关系。此外,还要研究这种
To prevent the oil from diluting the oil, a team of innovators at Neutra Stritz’s locomotive section recommended reducing the pressure in the pump suction chamber from 25 N / cm 2 (≈2.5 kg / cm 2) to 6-8 N / Cm ~ 2. If handled as such, the amount of oil leakage from the injection pump plunger will drop significantly, and diesel engine oil must not be replaced due to premature viscosity depression of 72 centistokes. Of course, before changing the pump suction chamber pressure, it is necessary to conduct an in-depth study to find out the relationship between the injection pump suction chamber pressure and the amount of oil leakage. In addition, we must study this
