Hydraulic Cylinder Guide: Seal Kits
密封套件用于关闭液压缸中元件之间的间隙. 关闭这些间隙是必不可少的,因为密封负责保持液压压力和防止流体动力系统中的污染物.
如果你正在考虑购买液压缸密封套件, you most likely have a few questions. 在这篇文章中,我们将概述你在购买之前需要知道的事情.
Are Hydraulic Cylinder Seal Kits Universal?

Short answer: no.
有许多类型的液压缸改造套件. 每个液压缸都有独特的杆径和内径, stroke length, cylinder length, pressure flow requirements, etc. 一些不同类型的液压缸密封套件包括标准, loaded lip, cast-iron piston rings, and fluorocarbon.
您需要的套件类型取决于活塞杆的行程速度, fluid media, fluid pressure range, and more. 你还必须确保套件中的密封件尺寸合适.
How to Select the Right Seal Size
确定液压缸密封套件的尺寸是一个简单的过程. 你需要卷尺和卡尺来测量. Take your time and be meticulous.
Step 1: Measure the Bore
确定买足球app推荐的内径,也就是买足球app推荐的内径. 用卷尺在汽缸的内筒上测量内径.
Step 2: Measure the Piston Rod
The piston rod is normally a chrome-plated, 连接在活塞上的一块圆形硬化钢. Measure its diameter with outside calipers.
步骤3:确定圆柱体的缩回长度
圆柱体的缩回长度是当圆柱体完全关闭(缩回)时,其针孔中心之间的距离。. 你的卷尺最适合这一步.
第四步:测量圆柱体的延伸长度
液压缸的延伸长度是液压缸完全打开时其销孔之间的距离. Again, use your tape measure to obtain this.
Step 5: Calculate Your Cylinder’s Stroke
简单地减去圆柱体的收缩长度从它的延伸长度. For example, if your retracted length was 12 inches, and your extended length was 34 inches, your stroke will be 22 inches.
第六步:对液压缸进行彻底的目视检查
Carefully evaluate your cylinder’s hose ports, 在哪些地方连接液压管线将流体输送到买足球app推荐. 寻找任何异常磨损的迹象,必要时订购更换配件.
Types of Hydraulic Cylinder Seals
液压缸密封的两种主要类型是:静态和动态. 静密封停留在一个地方,防止流体在没有运动的地方泄漏, such as where the piston and rod join.
另一方面,动态密封用于相对运动的部件. 动力密封的例子包括活塞密封, which control the motion of the cylinder; rod and buffer seals, which manage fluid leakage and lubrication; wiper seals, which keep dirt out of the system; and guide rings, 使所有的东西都整齐,防止磨损. 总之,这些密封在液压缸的有效运行中起着至关重要的作用.
Signs of Failure
当您突然遇到不可预见的故障时,液压缸密封套件是必不可少的. Some seal failures are easy to spot, such as oil leaking from around the cylinder, while others are more challenging.
A drop in hydraulic pressure, an overheated cylinder, loud clunking or banging noises, 高于正常的震动和振动都是你需要检查汽缸的迹象. 密封失效的其他潜在迹象包括:
- Excessive Wear:过度磨损往往是由于润滑不足或不当造成的,最终可能导致密封件撕裂和变色.
- Seal Hardening在高温条件下工作的液压缸会经历密封硬化, eventually leading to cracks, tears, and rips.
- Improper Installation在密封更换过程中一个常见的错误是测量密封而不是密封放置的槽. 使用错误的密封尺寸会导致漏油, contamination, 或者压力的下降会影响汽缸的性能.
- Contamination: 污物、碎屑、污泥、泥浆和其他元素会积聚在买足球app推荐和密封件中. If not taken care of, 问题将继续恶化,直到这些污染物到达活塞并影响汽缸的操作.
- Seal Fracture: Sudden impacts, shocks, 或者劣质密封件会导致密封件破裂(破裂)。, tearing, or ripping.
