原东德产E512联合收割机的发动机,采用的是柱塞式输油泵,它与国产柴油机上一般所用的柱塞式输油泵,工作原理相同,但在具体结构上稍有区别。当遇到E512上的输油泵损坏而又一时缺乏备件更换时,可用国产柴油机上的输油泵代用。例如国产4115柴油机的输油泵与E512的输油泵相比,后者的过滤网和集尘杯装在输油泵下部,前者的过滤网和集尘杯则装在进油管接头螺栓处;另外后者的进油管螺栓比前者的进油管螺栓稍短些。除此之外,其它部位以及整体工作性能参数都大体相同。因此作为总成件而言,不必进行任何改装即可代用。在1986年和1990年,我们两次把
The original East German E512 combine harvester engine, using a plunger pump, which is commonly used with domestic diesel engine plunger pump, the same working principle, but the specific structure of a slight difference. When encountered on the E512 pump damage and lack of spare parts replacement, available on the domestic diesel engine oil pump alternative. For example, domestic 4115 diesel engine pump and E512 pump compared to the latter filter and dust cup mounted in the lower part of the pump, the former filter and dust cup is installed in the inlet pipe bolts; the other The inlet pipe bolt is slightly shorter than the former inlet pipe bolt. In addition, other parts and the overall performance parameters are roughly the same. Therefore, as an assembly, it can be substituted without any modification. In 1986 and 1990, we put it twice
