2、打开泄油口R，而U口用一根油管引 出油箱，试运转时可以通过U口排气 。正常工作时U口需封死。 为防止壳体泄漏油直接被吸入吸油口 ，在T或L口需接另一根管子，把吸油 口与泄油口分隔开。 All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copy of passing by us. 3 APU泵在第一次启动前，或在更换备件时，要向泵的壳体中灌滿干净的 液压油。这样在泵启动时很快在各有相互运动配合面上形成支撑油膜，
3、 不会产生磨损。 同时，泵体轴承可以得到有效润滑，延长泵的使用寿命。 特例：A8泵的吸油口与泄油口在设计上相通，不用在壳体中加油，但在 打开吸油阀后要从泄油口放气。 Oil plugged All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications.

8、泵轴的轴向力限制 在泵的安装过程中不可使用蛮力（用锤 砸）。 也不可产生顶轴现象，否则会破坏泵内 各部件的预紧力，加大磨损或影响轴承 寿命。 All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications.
