液压油箱转向段前部 (1) 旁通开关 (2) 箱体排油滤清器 |
箱体排油滤清器 (2) 安装在制动器、举倾和转向液压油箱上。 自以下部件的箱体排油经过箱体排油滤清器至液压油箱的转向段:
- 液压风扇和转向活塞泵
- 液压风扇活塞马达
- 后桥润滑泵和马达
- 后桥、润滑和转向的风扇的电磁阀和歧管
箱体排油通过滤清器底座流入滤清器壳体。 机油充注滤清器壳体的内侧与滤清器滤芯之间的空间。 然后,机油流过滤清器滤芯,回流到滤清器底座。 机油从滤清器底座流至液压油箱。 滤清器滤芯过滤掉机油中的所有碎屑。
如果滤清器滤芯满是碎屑,将会阻止机油流动。 机油被阻止流动会导致滤清器滤芯内压力增加。 高压机油会使旁通阀开启。 此外,旁通开关 (1) 启动,驾驶室中记录一个警报。
然后,机油流经开启的旁通阀流向液压风扇和转向系统。 当机油不从滤清器滤芯流过时,机油中的碎屑将会损坏液压风扇和转向系统中的其他部件。
必须采用正确的维护保养步骤,确保滤清器滤芯没有堵满碎屑,这些碎屑会阻止干净的油流进入液压油箱。
