Hydraulic Cylinder Guide: 重新打包ing a Hydraulic Cylinder

作者:Adam Sgammotta b|

A hydraulic cylinder is an actuator that uses hydraulic fluid to move linearly 和 produce unidirectional force. These types of cylinders have a wide range of applications 和 can be found in l和ing gears, 矿车, 挖掘机, 喂食器, 制造设备. 

Because hydraulic cylinders are a frequently used component, 和 often must operate in a wide array of environments, they do require general maintenance every now 和 then. 重新打包ing hydraulic cylinders can help reduce oil leaks, 延长买足球app推荐的使用寿命, 并最终减少设备停机时间. 

在本文中, we’ll cover everything you need to know about repacking a cylinder, 包括准备和测试, 实际的重新包装过程, 在哪里你可以找到重新包装工具.

为什么要重新包装钢瓶?

如前所述, repacking a hydraulic cylinder is an essential preventative maintenance task. If left ignored, oil leaks will eventually develop. These oil leaks will eventually lead to premature replacement of your hydraulic cylinders 和 unplanned downtime. So, repacking your cylinder when it’s needed will ensure fewer production delays, 更低的成本, 效率更高. 

作为一般提示, you should always document any preventative maintenance work, as that will help you remember when it needs to be done next. 另外, 如果你注意到这些迹象, you will need to repack your cylinder as soon as possible:

  • 石油泄漏
  • 降低性能 
  • 漂流

准备 & 测试

Before you repack your hydraulic cylinder, you need to prepare it 和 test it for the repacking process. 

In terms of preparation, you’ll want to make sure you follow these guidelines:

  1. 确保买足球app推荐杆是直的.
  2. Verify that the inside of the barrel surface displays the appropriate cross-hatching.
  3. Always check to make sure there are no scars or gouging present.
  4. Finally, verify that the chrome plating on the cylinder’s rod isn’t damaged.

After you’ve prepared the cylinder, you’ll need to pressure test its internal seals. 要做到这一点，请遵循以下步骤:

  1. Carefully fill the cylinder itself from both sides with hydraulic fluid.
  2. Push air out of the cylinder by moving it through full stroke multiple times. 
  3. 此时此刻, you’ll need to pressurize the cylinder to extend it, which will allow you to look for signs of internal leakage.
  4. Then, retract the cylinder 和 check for leakage once again.

Once all of these steps have been completed, you can then move on to the actual cylinder repacking process.

如何重新包装

The process of repacking a hydraulic cylinder is fairly straightforward. This is another reason why it should become an integral part of your preventative maintenance program.

The repacking process involves the following steps:

  1. Disconnect all lines/hoses, otherwise, you won’t be able to remove the cylinder.
  2. 插入任何端口
  3. Release pressure from the cylinder, remove it from the unit, 和 then clean it.
  4. 此时此刻, you can remove both the gl和 和 the pin from the rod-end of the cylinder.
  5. 你也应该把活塞杆拿出来. Note that caution is of the utmost importance because rods are easy to damage 和 can be expensive to replace.
  6. Remove the piston from the rod—again, proceed with caution.
  7. Now, work on replacing the seals on your hydraulic cylinder, along with the O-rings. These can be replaced one at a time as needed.
  8. Check the entire assembly for signs of dust, dirt, or other debris. 根据需要清除任何障碍物.
  9. Carefully clean all of the parts that you have removed.
  10. Reassemble the piston by putting it back in the rod.
  11. 更换液压管路.
  12. Follow the steps in the previous section to test the hydraulic cylinder for any leaks.

That’s it— as stated, the process is straightforward 和 it shouldn’t take much time at all. 当你做这个的时候, be sure to remember how you disassembled the hydraulic cylinder 和 in what order so that you can make sure all parts end up back in their correct locations. 另外, be sure you underst和 what your torque specifications are to ensure your lock nut 和 screw or install ring is properly tightened.
