1问题的提出联合调节器对柴油机的调节是通过高压油对喷油泵供油量进行调节而实现的。可是，从我段1994年的运用情况看，由于联合调节器漏油造成机破、临修占了我段机破、临修较大比重（表1）。由于联合调节器油封轴圈（以下简称油封）漏油具有突然性和乘务员不易处理的特点， 1 The question put forward Joint regulator on the regulation of diesel engine is through the high-pressure oil to fuel injection pump to adjust the amount achieved. However, judging from the application of my paragraph in 1994, due to the joint regulator leakage caused by mechanical leakage, Lin repair accounted for a large part of my machine broken, a large proportion of temporary training (Table 1). As the joint regulator oil seal shaft (hereinafter referred to as the oil seal) has a sudden leakage and steward is not easy to deal with the characteristics,
