Hydraulic Cylinder Guide: Identifying Parts of Hydraulic sb沙巴体育投注

When one hydraulic cylinder part fails, it will usually impact the performance of other parts. That’s why all hydraulic cylinder repairs require a full disassembly 和 reassembly of the cylinder itself. 在拆卸过程中, each part is thoroughly examined for general 穿 和 tear 和 signs of failure.

If your hydraulic cylinder is underperforming, or has failed altogether, keep reading this article. 在这, we’ll break down the major parts of a hydraulic cylinder, 各部分的功能, 以及他们如何作为一个整体一起工作. Knowing this information can help guide you during repairs, 识别潜在问题, 并且可能节省你的时间和金钱.

桶

The first major part of a hydraulic cylinder is the barrel, which is a smooth cylinder that keeps pressure inside the cylinder. Designed internally to reach the correct diameter, most cylinder barrels have exterior finishes between four 和 16 micrometers.

Additionally, there are two major types of barrels: single-acting 和 double-acting. The main difference between the two is that single-acting barrels have welded ports on the end of the base, while double-acting barrels have welded ports at both bases.

Hydraulic cylinder heads are the endpoints where an extended piston rod delivers productive force. The primary purpose of the cylinder heads is to prevent leakage of pressure from the pressure chamber at both ends of the cylinder.

Heads can either be attached to barrels via a screw connection, 弹簧环, or, 通常更少, 通过BOB沙巴体育登录. Head interiors are finely grooved to coordinate with gl和s, rod 刮水器s, 和 piston rod seals.

液压缸底座/压盖

也叫杆端, the hydraulic cylinder base is the visible opening that a cylinder rod connects to. The gl和 is attached with tie rods, 螺栓, welding, 或线程ing. Hydraulic cylinders incorporating a tie rod utilize high-strength steel rods that are threaded for holding end caps to the barrel. BOB沙巴体育登录体汽缸没有拉杆. Instead, the barrel is directly welded to end caps while ports are welded to the cylinder barrel.

液压缸活塞

Inside hydraulic cylinders is the piston that functions to isolate pressure zones within the barrel. Pistons are manufactured to fit metallic or rubber seals that can be double-acting or single-acting. 便于直线运动的传递, 活塞杆用螺母连接, 螺栓, 或线程. Hydraulic cylinders retract or extend depending on the location of applied pressure relative to the piston. 例如, pressure exerted on the cap end results in the extension of the rod outside the cylinder barrel.

活塞杆

Typically made from cold-rolled steel fortified with hard chrome plating, the piston (cylinder) rod is attached to the cylinder head 和 the piston. Hard chrome is essential for giving piston rods the ability to last a long time. The piston rod also enhances the seal, which helps prevent leaks.

密封压盖

液压缸也有密封盖, which typically have a number of seals within them, 主要包括, 二次, 穿, 刮水器, 拳击手, 和静态.

海豹

As previously mentioned, there are many seals inside a seal gl和. The purpose of each seal is to prevent leaks from occurring beyond the interface of the head 和 rod. 海豹 are also exclusively designed to accommodate a cylinder’s speed, 工作压力, 工作温度.

When hydraulic cylinders are used in low environmental temperatures, it’s recommended that the seals be made from nitrile rubber materials. 另一方面, hydraulic cylinders operating in high-temperature conditions 应该 be made from fluoroelastomer, a rubber compound providing a strong fluorine-hydrogen bond that makes it resistant to extremely hot (和 cold) temperatures.

最后,海豹 应该 be replaced if they are damaged (broken, ripped, worn edges, etc.,). 虽然它们很容易拆卸和更换, it’s vital that you purchase the right type of seal replacements for your cylinder. 请 visit our blog to learn more about replacing seals.
