1、检查山东装载机//qlhzp.com/动臂油缸的内漏情况，改进液压系统设计，采用先进的优先阀与负荷传感全液压转向器形式新系统，按照转向要求，优先向其分配流量，无论负载大小、方向盘转速高低均能保证供油充足，剩余部分可全部供给工作装置回路使用，从而消除了由于转向回路供油过多而造成功率损失，提高了系统效率，降低了液压泵的工作压力。
Check the internal leakage of Shandong loader boom cylinder, improved hydraulic system design, advanced load-sensing priority valve and hydraulic steering gear in the form of the new system, according to the steering requirements,assign priority traffic, regardless of load size, low speed steering wheel can ensure adequate oil supply, the remaining part can all work equipment supply circuit use, thereby eliminating the steering circuit oil caused by excessive power losses, improve system efficiency and reduce the hydraulic pressure of work.

2、检查山东装载机操纵阀。首先清洗安全阀，检查阀芯是否磨损，优化设计动臂油缸和液压泵造型，降低系统工作压力。
Check the Shandong loader control valve. First clean the safety valve, check valve wear, optimal design boom cylinder and hydraulic modeling, reduce system operating pressure.

3、测量山东装载机//qlhzp.com/液压泵的压力。若压力偏低，则进行调整，加压力仍调不上去，则说明液压泵严重磨损，定期添加或更换液压油，保持液压油的清洁度，加强日常检查和维护。
Shandong loader hydraulic pressure measurement. If the pressure is low, then make adjustments, plus the pressure is still not tune up, then pump badly worn regularly add or replace hydraulic oil, hydraulic oil to maintain cleanliness, strengthen the routine inspection and maintenance.
