在全自動混凝土攪拌車液壓係統和液壓元件中，由於加工誤差、裝配誤差以及配合表麵間的相對運動，總會產生一些縫隙，當油液流經這些縫隙時，就會產生漏油現象，這種現象稱為漏油。密封裝置的泄漏主要有密封環的內泄漏和骨架旋轉油封的外泄漏，其原因分述如下：
In the hydraulic system and hydraulic components of the fully automatic concrete mixer, due to processing error, assembly error and relative movement between mating surfaces, there will always be some gaps. When the oil flows through these gaps, there will be oil leakage, which is called oil leakage. The leakage of the sealing device mainly includes the internal leakage of the sealing ring and the external leakage of the skeleton rotating oil seal. The reasons are as follows:
（1）密封環的內泄漏原因
(1) Cause of internal leakage of sealing ring
A密封環與被密封零件表麵有相對運動，引起不正常磨損。
A There is relative movement between the sealing ring and the surface of the sealed part, causing abnormal wear.
B密封環接觸不良。
B Poor contact of sealing ring.
C密封環磨損不均勻。
C The seal ring is worn unevenly.
D密封環質量差，引起變形或斷裂。
D The seal ring is of poor quality, causing deformation or fracture.
（2）骨架旋轉油封的外泄漏原因
(2) Causes of external leakage of framework rotating oil seal
A被密封零件的徑向跳動超過允許值，使骨架旋轉油封磨損不均勻。
A The radial runout of the sealed parts exceeds the allowable value, which causes uneven wear of the skeleton rotating oil seal.
B密封件質量差，在高溫下油封唇部變形，導致被密封件的圓柱表麵拉傷。
B The quality of the seal is poor, and the lip of the oil seal is deformed under high temperature, resulting in the strain on the cylindrical surface of the seal.
內泄漏是液壓係統內業液壓元件內部油液從高壓區域到低壓區域的泄漏；外泄漏是液壓係統內的油液泄露到液壓係統外麵的瀉漏，如液壓油缸的泄漏和油液管道的泄漏等。
Internal leakage refers to the leakage of internal oil in hydraulic components of hydraulic system from high pressure area to low pressure area; External leakage refers to the leakage of the oil in the hydraulic system to the outside of the hydraulic system, such as the leakage of the hydraulic cylinder and the leakage of the oil pipeline.
液壓係統中產生泄漏的原因，是縫隙兩端存有壓力差，或組成縫隙的兩配合表麵相對運動。泄漏將使液壓係統的效率降低並汙染環境。
The leakage in the hydraulic system is caused by the pressure difference at both ends of the gap or the relative movement of the two mating surfaces that make up the gap. Leakage will reduce the efficiency of the hydraulic system and pollute the environment.
減少和預防內泄漏的措施：嚴格控製液壓元件中有相對運動部位之間的配合間隙，其原則是即要保證良好的密封性，又要保證較小的運動阻力
Measures to reduce and prevent internal leakage: strictly control the fitting clearance between the relative moving parts in the hydraulic components, and the principle is to ensure good sealing and small movement resistance
減小和預防外泄漏的措施：提高液壓油缸活塞杆的密封性，裝配中要正確安裝各種管道等連接件，注意液壓元件配合表麵的密封性，尤其是對各種液壓元件的接頭處更要特別重視。
Measures to reduce and prevent external leakage: improve the sealing of the piston rod of the hydraulic cylinder, correctly install various pipes and other connectors during assembly, pay attention to the sealing of the mating surface of hydraulic components, especially the joints of various hydraulic components.
