All rights of disposal as copyofpassing by us.2APU液压泵的安装 液压泵的安装位置可以有多种选择但前提条件是保证泵的壳体内充满液压油长期停用后不得无润滑运转 如果液压泵安装在油箱内，为保证吸油效果，吸油口S要安装一吸油管 液压泵在油箱内不能保证自动充油，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 copyofpassing 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，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Oilplugged© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications.

All rights of disposal as copyofpassing by us.5泵的不同安装方向1) 泵轴水平安装2) 泵轴垂直向上安装3) 泵轴垂直向下安装4) 泵轴水平侧向安装© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copyofpassing by us.6泄油管上安装止回阀 弯轴泵水平安装在油箱外部液压之上时，为保证壳体油液漏空，必要时加一单向阀。

All rights of disposal as copyofpassing by us.8保证油箱的最低液位 泵安装在油箱内时，注意最低液位不能低于最高的泄油口© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copyofpassing by us.9检查泵的旋向 首次启动液压泵时，从电机后风扇位置正对泵轴，检查泵的旋向是否正确。

如不正确可以对掉动力线的两个接线头泵长时间反转会导致损坏© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copyofpassing by us.10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. All rights of disposal as copyofpassing by us.11用万向轴驱动液压泵 安装时万向轴的两端必须保持等角度 轴两端连接处应对称，转动接头应在同一平面内，无明显安装偏差连接不对称© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copyofpassing by us.12泵的安装是否符合要求: （以A10VSO为例） 垂直安装，油箱之内。

L1口需要一根油管，防止泄漏油直接被吸入S口两管间距最小200mm. 垂直安装，油箱之外为使轴承得到有效冲洗，L1管需要向上折弯，高出轴端面吸油管在液面之上距离最高hmax=800mm. 浸入液面最小长度hmin=200mm. 保证最小吸油压力0.8 bar.© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copyofpassing by us.13泵的安装是否符合要求: （以A10VSO为例） 水平安装，油箱之下接上面的L1口L口堵住吸油管浸入液面最小长度hmin=200mm. 保证最小吸油压力0.8 bar.© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications. All rights of disposal as copyofpassing by us.14泵的安装是否符合要求: （以A10VSO为例）吸油压力：最小绝对压力0.8bar.泄油压力：不能高于吸油压力0.5 bar，最高不能超过2 bar (绝对压力)© All rights reserved by Bosch Rexroth AG, as well in cases of trade mark rights applications.
