CTR3-050/M4A/GP2-0070/D11N齿轮油泵的压力终是要用扬程来体现，理论上只要齿轮油泵的零件强度和驱动设备能量足够，输液就可达到任意高度。但是，由于齿轮和泵体之间具有一定的间隙(泵壳内侧面间隙为0.04~0.1mm，径向间隙为0.1~0.15mm)，所以扬程提高到一定程度时，就会产生液体倒流现象，扬程就降低了，也就是压力降了。因此产生没有压力的原因，凡是能使侧面间隙和径向间隙加大的都是形成没有压力的原因。检查一下溢流阀，刚起动时油温低，粘度大，压力高，随着温度升高，粘度降低，压力也随之下降，将溢流阀调节一下，问题就有可能解决了。溢流阀如果设定值不当，达到一定压力就泄压了，从而让客户以为是压力达不到，实际上是溢流阀设定值不当。客户在选型的时候，如果对压力有特殊要求，定货时一定向我们提出你所要求的压力值，我们可以将溢流阀的泄压值调到你所需要的程度。检查齿轮油泵所在的油路，在检查仪表，这点很重要。CTR3-075/P4/GP2-0178/C600N

(6)检查挺柱体。喷油泵体和挺柱体之间的标准间隙为0～0.03mm，如过0.2mm ，则应更换零件。

(4)变速泵的加工质量。
从主机厂得到的反馈信息，与变速泵组装在一起的齿轮泵油封窜油问题较严重，因此变速泵的加工质量对窜油也有较大的影响。变速泵装在变速箱输出轴上，齿轮泵又通过变速泵止口定位而装在变速箱输出轴上，如果变速泵止口端面对齿轮回转中心的跳动差(垂直度)，也会使齿轮轴回转中心与油封中心不重合而影响密封。变速泵加工、试制过程中，应检查回转中心对止口同轴度及对止口端面的跳动。CTR3-035/P4/GP1-0091/C400N
