1.泄漏的原因(1)活塞杆与导向套相对运动表面间泄漏原因:活塞杆外伸表面与外界各种杂质接触,使活塞杆表面产生麻点、沟槽、伤痕或锈渍等,加剧了密封圈的磨损,有时甚至会切伤密封圈。(2)缸筒与端盖(或导向套)间密封件漏油原因:密封圈压缩量不足;密封圈损坏;缸筒和导向套密封槽的表面
1. Causes of Leakage (1) Leakage between the relative movement surfaces of the piston rod and the guide sleeve Cause: The protruding surface of the piston rod contacts with various impurities outside to make the surface of the piston rod produce pitting, grooves, scars or rust stains, etc., which aggravate The wear and tear of the seal, and sometimes even cut the seal. (2) Leakage of seals between cylinder barrel and end cap (or guide sleeve) Cause: Insufficient amount of seal ring compression; failure of seal ring; surface of cylinder sleeve and guide sleeve seal groove
