How to fix a leaking hydraulic cylinder

Hydraulic cylinder is an integral component that assists machines to function properly. They harness the power of fluids to produce pressure, which makes stuff move, like those hydraulic arms on a bulldozer or a jack lift. But occasionally, these cylinders can begin to leak. With that said, there is no time to waste if this begins to happen. A leak might mean trouble and wasted fluid. Repairing a leaky hydraulic cylinder can be beneficial not only to help prevent machine-downtime but also in saving money. If there is a leak, there are ways to seal it well and issues that may occur with hydraulic cylinders. We at Junfu Hydraulic know how crucial the uptime of your machines are

How to Properly Seal a Leaking Hydraulic Cylinder

When you have a hydraulic cylinder leaking, the best thing to do is find the leak and then address that problem Examine the seals, which are the things that should be preventing fluid from getting out of there. Occasionally, the seals can just wear down with use. If you see any cracks or damage, it’s time to swap in new ones. You can purchase new seals, or perhaps you can apply a sealant designed specifically for hydraulic systems. Be sure to clean the area around the leak before applying the sealant. This is key to get the seal to bond

After cleaning, carefully follow directions for the sealant or seals you have. If you’ve used sealant, make sure it is free from lumps and ensure that you let it dry as per the directions. If you are replacing seals, make sure they are the right size. You don’t want them to overreach or underperform. Also examine the surface of the cylinder; if it’s scratched or marred, you might want to give it a light sanding or polishing treatment in order to prevent future leakage. After reassembling everything, top off the hydraulic fluid and test for leaks. Always remember, safety is key! Always wear gloves and safety glasses when rebuilding hydraulic cylinders

There are many causes for hydraulic cylinder failure, which is why it’s important to understand the most common issues so you can solve them on-the-fly

 A common problem, for example, is leaky seals. Seals are composed of rubber or other materials that can wear down or become damaged. When those seals fail, hydraulic fluid escapes the system, and pressure is lost. But the solution is easy and relatively cheap: Just check the seals for wear every so often, replacing any that feel brittle or are visibly worn. Fortunately, the seals can be changed out easily with repair kits from Junfu Hydraulic. Yet another issue is exterior corrosion on the cylinder. If left for long periods exposed to moisture, the cylinder can rust Remove it, and paint or coat the exposed metal if necessary. This will prevent the cylinder from rusting int eh future. Another common failure is cylinder warpage. Heavy loads or working outside the cylinder’s range can result in this. To avoid bending, be sure to use the cylinder appropriate for the size of concrete each time. If there is, you may need to replace the cylinder or hire a professional to make repairs. Finally, the cylinder can be damaged by contamination in the hydraulic fluid. The system may be damaged by dirt, water or foreign material. The fix is to change the hydraulic fluid regularly and also filter it clean. Keeping everything clean will ensure that your hydraulic cylinder operates as it should. Knowing about these common failures — and how to remedy them — could save you time, money (and grief). Junfu Hydraulic is always there to help you with good products and knowledge
