液压缸活塞杆端的精密加工壳体,用于安装和固定杆密封件、防尘圈及轴承。
活塞杆密封盖,又称密封压盖,是安装在液压缸活塞杆端的精密加工壳体部件。它作为杆密封件、防尘圈以及有时轴承的安装和固定机构。其主要功能包括保持液压油液密封、防止外部污染物进入缸体,以及在伸缩循环过程中为活塞杆提供结构支撑。在动臂油缸中,它承受高压、动态载荷和环境暴露。 活塞杆密封盖通过在固定缸头和运动活塞杆之间形成密封界面来工作。它通过压盖螺母或螺栓的机械力,将密封元件(如U形圈、O形圈或杆密封件)压缩并定位在杆表面。这种压缩形成一道屏障,防止液压油泄漏,同时阻挡污垢、水分和碎屑进入缸孔,确保液压系统高效运行并延长部件寿命。

These terms are often used interchangeably. Technically, the rod gland refers to the entire assembly that houses seals, while the seal gland may specifically denote the part compressing the seals. In practice, both describe the component retaining rod seals in hydraulic cylinders.
Inspect during routine maintenance every 500-1000 operating hours. Replacement depends on operating conditions: typically 1-3 years for standard use, or immediately if leakage, contamination ingress, or rod scoring is observed.
Minor damage like seal groove wear can sometimes be machined and fitted with oversized seals, but replacement is recommended for significant wear, cracks, or corrosion to ensure reliability and prevent cylinder failure.
