How Do You Tell If a Hydraulic Cylinder Is Leaking?

hydraulic cylinder rebuildThe best way to confirm if your machine leaks is to clean the cylinder with soap and water and inspect for anything abnormal. You want to check for external damage to the barrel or rod, which could be impacting the cylinder barrel. Another sign of a hydraulic oil leak is a crack around the clevis area. If you notice any external damage, further investigation is warranted. To do a more thorough inspection, it is best to have a professional remove the cylinder from its housing. 技术人员可以检查和测量所有直径,以确保它们正确对齐.

What Are the Causes of Leaking Hydraulic Cylinders?

Often referred to as a cylinder bypass, various factors may cause a leaking hydraulic cylinder. These reasons include:

  • Worn or outdated hydraulic cylinder piston seals.
  • 买足球app推荐部件内部损坏,包括密封件、活塞或买足球app推荐筒.
  • Piston nut loosening or dirty hydraulic oil.
  • Metal particles seeping into the cylinder’s internal components.

液压缸的泄漏也可能是由机器中心的鼓筒引起的, causing uneven distribution. This situation causes the oil to travel around the piston and fail to hold the load the stroke requires.

Can You Stop a Leaking Hydraulic Cylinder?

The best way to stop a hydraulic cylinder from leaking is to have a technician perform a seal replacement. However, a seal replacement is only an option if all other parts of the cylinder are in good working condition. Technicians can use OEM or aftermarket seals, which can be sourced from a variety of wholesalers. Generally, a technician will need to remove the cylinder from the housing, strip its mechanisms, clean the components and measure all parts so it can be rebuilt.

How Do You Remove a Damaged Hydraulic Cylinder?

在拆卸损坏的液压缸时,安全是首要考虑的问题. First, you need to examine the unit and take note of all components. Understanding the hydraulic system and if there are any stored energy sources present is vital to preventing injury. 储存的能量来源可能来自蓄能器或买足球app推荐上的重物.

Second, the unit must be isolated and adequately classified, so it is not mixed up with other machines nearby. 一旦你给设备贴上标签并确认没有储存能量, remove both ends that attach the cylinder to the hydraulic unit. Before you complete this step, ensure the cylinder is not pressurized. Check the clevis pins and see if they can be moved. 如果销太紧而无法移动,则可能仍有重物作用在买足球app推荐上. You will need the assistance of an engineering specialist to remove the clevis pins if they are too tight to remove manually.

最后,确保你有合适的清洁设备来完成清除. 将钢瓶从外壳中取出可能是一项脏乱的工作,石油泄漏也很常见. Plug the hydraulic hoses and ports to limit the risk of an oil spill. The cylinder can be removed from the housing once the ends and pins have been removed and stored.

How Do You Disassemble a Hydraulic Cylinder?

Disassembling a cylinder is a complex process and is best left to a professional with specialized hydraulics experience. However, it is important to understand the steps involved if you regularly work with cylinders. First, you need to identify the cylinder type. 有些买足球app推荐很小,无需专门工具即可拆卸. Most cylinders, however, are large enough to require specialized equipment to separate the cylinder from the boom assembly. The piston nut also needs to be removed with controlled hydraulic pressure to ensure the safety of everyone on site.

你必须确保你有适当的设备来固定汽缸筒. 在加工过程中,还需要工具将压盖固定在买足球app推荐筒上. 有时压盖求推荐好的买球APP到汽缸上,需要用重型设备拆卸. 如果压盖求推荐好的买球APP买足球app推荐上,则机组可能无法经济地进行维修.  如果阀盖没有与设备熔接,则可以用扳手或套筒将其拆卸.

After the gland is removed, 该杆需要加强一个特定的工作台夹具,以安全地移除其他组件. The main element that should be removed at this time is the piston nut. Extra care must be taken to ensure no part of the cylinder is damaged during the removal process.

Tips on How To Repair a Hydraulic Cylinder

While you may think that hydraulic cylinder repair is an easy task, but as with many projects, 如果你没有做好准备,事情很快就会变得复杂, expertise, or tools.

Repairing a Wire Ring Cylinder

You’ll need to disassemble the wire ring cylinder by retracting the rod assembly ad removing the external steel wire ring. Remove accumulated dirt or oil from around the cylinder head. Using your mallet or punch, push the head into the cylinder tube until you can see the internal groove and reach the internal wire ring. Using the plastic removal ring from the seal kit, 将其插入内部凹槽,带羽毛的一端指向管子.

Hold one end of the ring tightly in the groove with a screwdriver while inserting the other end into the groove. Both tips should snap in fully and securely before attempting to remove the rod to prevent them from being caught between the head and tube. You should now be able to extend the rod to pull the head from the tube.

Take out the removal ring as well as the locknut, piston, and head. Clean with the solvent, then closely inspect the parts for damage like the presence of burrs, scratches, or scuffs. Polish and smooth as needed. Now you can access the seals for replacement.

Repairing a Threaded Head Cylinder

Begin your threaded head cylinder disassembly by loosening the set screw and the end cap and removing the piston, rod, and gland assemblies. Loosen the lock nut to remove the piston from the rod assembly. 一旦活塞不挡路,拆下密封件并用溶剂清洗零件. 检查买足球app推荐管、杆和活塞是否损坏,必要时进行抛光.

更换密封件并重新安装杆,然后用锁紧螺母将活塞固定在杆上. Lubricate the seals and inside the tube with hydraulic oil, then install the piston, gland, end cap, and rod. 在更换买足球app推荐端盖之前,可以在螺纹上使用乐泰防卡扣. Finally, tighten the cylinder and set the screw to the appropriate torque.

After the repair, 您应该能够通过检查损坏的类型来诊断问题的原因. This step is critical to keep from repeating the rebuild and repair process. Our experienced technicians can help you to identify signs of problems and address the source of the problem.

Types of Cylinders We Repair

Tie-Rod Units Cylinders

Tie-rod cylinders are among the most common cylinders in the U.S. They are held together by several threaded tie bolts that secure two end caps to the unit’s barrel. The bolts also secure the baseplate and the head to the cylinder tube. Tie-rod cylinders typically come equipped with seals to prevent leakage. These units come in both small-bore and large-bore iterations. 小口径装置有四个杆,而较大的装置可以有20个或更多的杆. 买足球app推荐执行液压缸更换小缸径和大缸径拉杆缸. 这些单位是相对容易拆卸服务,维修或定制.

Welded Cylinders

Welded cylinders come with the end caps welded to the machine’s barrel. Other components, including the mounts, are welded to the lid. 虽然这些设计坚固可靠,但它们不容易拆卸和维修. 如果你的求推荐好的买球APP买足球app推荐需要修理,你可能需要购买一个新的单位. Yates can help you decided the best course of action for your welded hydraulic cylinder rebuild process.
