液压缸可以修理吗?

液压缸 are both powerful 和 reliable, but can also break down or wear out over time. 密封泄漏, 腐蚀, 和 piston damage are some of the most common issues that you may experience with your hydraulic cylinders. Thankfully, most cylinders can undergo hydraulic cylinder repair.

什么是液压缸?

液压缸 are simple machines that 应用 force in a linear direction. They are composed of a metal tube, a piston with an attached rod, 和 mounting brackets.

There are two types of hydraulic cylinders: single-acting 和 double-acting. 

Single-acting hydraulic cylinders push the rod in one direction. When the rod moves back in the other direction, hydraulic pressure drops. Double-acting cylinders work differently, as they exert hydraulic pressure in both directions. Both types may require hydraulic cylinder repair in case of failure.

液压缸维修

液压缸 can be repaired, but you should never attempt these repairs on your own. Working with a trained technician will ensure fewer mistakes 和 a faster turnaround time. 虽然液压缸设计简单, you must be familiar with them in order to efficiently repair them. 当技术人员执行 液压缸修理, they take the entire mechanism apart 和 reassemble to find the root cause of the issue. 

液压缸故障的常见点

There are several common points of hydraulic cylinder failure. 这些包括活塞，杆，密封件和封头.

活塞

The pistons in hydraulic cylinders are one of the most common points of failure. 在轻型应用中尤其如此. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications. 

When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydraulic pressure that the piston is able to deliver. 如果你的活塞测量有问题, 它需要更换, 与安装的任何磨损带一起.

杆

杆s are perhaps the most likely culprit of a hydraulic cylinder failure. 杆s often develop small cracks after long periods of heavy use. A technician will use a special dye to check for cracks in the rod.

Bent rods commonly cause hydraulic cylinder failures. A rod only needs to be bent very slightly for the cylinder to fail. One of the easiest ways to check for a bent rod is to inspect the chrome finish. If it is bright 和 shiny on one side, but worn off on the other, the rod is bent. Thankfully, bent rods can often be repaired by straightening in a press.

海豹

There are seals on both the piston 和 the rod of a hydraulic cylinder. If these seals leak, the cylinder will not be as powerful. Additionally, all of the oil will eventually leak out 和 the cylinder will fail. Unfortunately, damaged seals are often signs of more serious problems. While the seals themselves should certainly be replaced, the piston 和 rod should also be inspected.

A piston seal failure often indicates that the barrel has become distorted. 有时, the barrel is the only thing that needs to be replaced, but sometimes a distorted barrel is often caused by a problem with the piston. If this is the case, the entire cylinder must be replaced. 

If the rod seal has failed, the most likely cause is a bent rod. As previously mentioned, bent rods can often be fixed in a press. A rod seal failure could also be caused by a worn guide bush. A worn guide bush can be quickly 和 easily replaced by a qualified technician.

Head

It is fairly rare for the head to be the cause of a hydraulic cylinder failure, but it can happen. 缸盖把连杆和活塞连接起来. The most common type of head failure occurs when the head is distorted so that it is bigger than the rod. 头部尺寸不应超过 .直径比棒子大0.04英寸. If it does, it must be replaced, or a bronze bush must be added.

It is also possible for the head’s seal grooves to be distorted so that they are significantly bigger than the rod. 如果密封槽的面积大于 .016 of an inch larger in diameter than the rod, the head must be replaced.
