装载机为什么会出现转向沉重？

1、转向泵内漏过大或轴油封漏油，造成供油量不足；
Lose a large steering pump or shaft seal leakage, resulting in insufficient fuel supply;
2、单向稳定分流阀被杂质卡住或弹簧失效，造成供油量不足；
Stable way diverter valve is stuck impurities or spring failure, resulting in insufficient fuel supply;
3、转向器的转子、定子副由于径向或轴向磨损，造成间隙过大内漏增加，表现慢转沉而快转轻；
Steering rotor, stator, vice due to radial or axial wear, resulting in increased internal leakage gap is too large, the performance of slow and fast turn light switch Shen;
4、转向器阀块的安全阀由于液压冲击和机械振动，造成调压螺杆松脱，使系统压力偏低，使转向沉重，甚至不能转向；安全阀调压弹簧变形、失效或阀芯被污物颗粒卡住，造成安全阀处于卸荷状态；阀块的过载阀失效，同样会造成转向沉重，表现为方向盘转动，转向缸动作滞怠或不动。
Safety valve diverter valve blocks and hydraulic shock due to mechanical vibration,resulting in the regulator screw loose, the system pressure is low, the steering heavy, not even turning; regulator valve spring deformation, failure or spool is dirt particles stuck, causing the safety valve in the unloading state; overload valve block failure, it will also cause heavy steering, the performance of the steering wheel, steering cylinder motion lag lazy or does not move.
5、转向器进、回油口的钢球单向阀失效会造成转向沉重，表现快转和慢转均沉重，转向缸动作慢。
Steering into the oil return port of the ball check valve failure will cause the steering heavy, fast-forward and slow transfer performance are heavy, slow steering cylinder movement.
6、转向缸活塞密封的失效或局部失效，造成转向沉重。
Steering cylinder piston seal failure or partial failure, resulting in heavy steering.
7、转向系统中有气。
Steering system with gas.
