1 油泵不转故障原因:1、取力器故障或损坏;2、操纵机构故障:齿轮脱开,操纵机构联接件断裂:3、传动部分故障:键破裂,万向节断裂:4、油泵内部滞死或有尘垢. 对应排除方法:1、拆散并检查:2、拆卸,检查,调整;3、检查、更换;4、拆散、检查,修理. 2 油泵运转正常,但翻斗倾卸异常故障原因:1、油缸缺油;2、控制滑阀开启不足;3、油泵止回阀工作不良。有尘垢(如翻斗上升或下降速度太慢,提高油泵转速后仍不见好转,则说明止回阀故障);4、漏油:5、活塞及油缸内部故障.
1 pump does not turn the cause of the malfunction: 1, the power take off or damage; 2, the control mechanism failure: gear off, the operating mechanism link fracture: 3, the transmission part of the failure: key rupture, universal joint fracture: 4, Stagnant or dirt. Corresponding exclusion method: 1, disassemble and check: 2, disassemble, check and adjust; 3, check and replace; 4, disassemble, check and repair. 2 oil pump is operating normally, : 1, tank lack of oil; 2, control valve open insufficient; 3, the pump check valve work bad. A dust scale (such as tipping bucket rise or fall too slow to improve the pump speed has not improved, then the check valve failure); 4, oil spills: 5, piston and cylinder internal failure.
