裝載機(jī)液壓系統(tǒng)的泄漏主要有兩種，一是固定不動部位（即靜接合面，如液壓缸缸蓋與缸筒的接合處）密封的泄漏；二是滑動部位（即動結(jié)合面，如液壓缸活塞與缸筒內(nèi)壁、活塞桿與缸蓋導(dǎo)向套之間）密封的泄漏，亦可分為內(nèi)泄漏和外泄漏。
Shandong loader hydraulic system leak there are two, one is fixed and the site (ie static joints, such as hydraulic cylinders and cylinder head junction) seal leakage; two sliding parts (ie moving the joint surface, hydraulic cylinder between the piston and cylinder wall, piston and cylinder head guide sleeve) seal leakage, can be divided into internal leakage and external leakage.

裝載機(jī)內(nèi)泄漏主要產(chǎn)生在液壓閥、液壓泵（液壓馬達(dá)）及液壓缸內(nèi)部油液從高壓腔流向低壓腔；山東裝載機(jī)外泄漏主要產(chǎn)生在液壓系統(tǒng)的液壓管路、液壓閥、液壓缸和液壓泵（液壓馬達(dá)）的外部，即向零部件的外面滲漏。具體表現(xiàn)為管接頭、密封件、元件接合面、殼體及系統(tǒng)自身原因而引起的油液泄漏。
Leakage is mainly produced in the hydraulic valve, hydraulic pump (hydraulic motors) and hydraulic cylinder inside the oil flow from the low pressure chamber hyperbaric chamber Shandong loader; Loader Shandong external leakage is mainly

produced in the hydraulic lines of the hydraulic system, hydraulic valves, hydraulic cylinders and the outside pump (hydraulic motor) external, namely parts of leakage. Specific performance fittings, seals, element joints, fluid leak

case and the reasons caused by the system itself.
