1、檢查山東裝載機(jī)http://www.hdwzhs.com/動(dòng)臂油缸的內(nèi)漏情況，改進(jìn)液壓系統(tǒng)設(shè)計(jì)，采用先進(jìn)的優(yōu)先閥與負(fù)荷傳感全液壓轉(zhuǎn)向器形式新系統(tǒng)，按照轉(zhuǎn)向要求，優(yōu)先向其分配流量，無(wú)論負(fù)載大小、方向盤(pán)轉(zhuǎn)速高低均能保證供油充足，剩余部分可全部供給工作裝置回路使用，從而消除了由于轉(zhuǎn)向回路供油過(guò)多而造成功率損失，提高了系統(tǒng)效率，降低了液壓泵的工作壓力。
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、檢查山東裝載機(jī)操縱閥。首先清洗安全閥，檢查閥芯是否磨損，優(yōu)化設(shè)計(jì)動(dòng)臂油缸和液壓泵造型，降低系統(tǒng)工作壓力。
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、測(cè)量山東裝載機(jī)http://www.hdwzhs.com/液壓泵的壓力。若壓力偏低，則進(jìn)行調(diào)整，加壓力仍調(diào)不上去，則說(shuō)明液壓泵嚴(yán)重磨損，定期添加或更換液壓油，保持液壓油的清潔度，加強(qiáng)日常檢查和維護(hù)。
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.
