Hydraulic cylinders are powerful tools that can lift, push, and pull heavy objects. However, when the hydraulic cylinder becomes stuck, it can cause a lot of problems. In this article, we’ll discuss the different causes of a stuck hydraulic cylinder and how to unstick it.
What Causes a Hydraulic Cylinder to Become Stuck?
There are several factors that can cause a hydraulic cylinder to become stuck, including:
Contamination is one of the most common causes of a stuck hydraulic cylinder. Even tiny particles of dirt or debris can prevent the piston from moving freely, resulting in the hydraulic cylinder becoming stuck.
2. Malfunctioning Seal
Another possible cause of a stuck hydraulic cylinder is a malfunctioning seal. A malfunctioning seal can cause a leak, which can restrict the movement of the piston and cause the hydraulic cylinder to become stuck.
3. Pressure Imbalance
Sometimes, a pressure imbalance can cause a hydraulic cylinder to become stuck. If the pressure in the cylinder is too low or too high, it can prevent the piston from moving and cause the hydraulic cylinder to become stuck.
How to Unstick a Hydraulic Cylinder
If your hydraulic cylinder is stuck, there are several steps you can take to try to unstick it:
1. Check for Contamination
The first step is to check for contamination. Remove the cylinder and inspect it for any dirt or debris that could be preventing the piston from moving freely. If you find any contaminants, use compressed air to blow them out of the cylinder.
2. Check the Seal
If the contamination check does not reveal any problems, then you should check the seal. Remove the seal and inspect it for any signs of damage or wear. If the seal is damaged, replace it with a new one.
3. Balance the Pressure
If the seal is not damaged, then you should check the pressure in the cylinder. Make sure the pressure is balanced and not too low or too high. If the pressure is off, adjust it to the proper level.
4. Apply Pressure
Once you have checked for contamination, inspected the seal, and balanced the pressure, you can try to unstick the hydraulic cylinder by applying pressure to the piston. If this doesn’t work, you may need to use a wrench or other tool to manually move the piston.
5. Call for Professional Assistance
If none of the above steps have worked, then you should call for professional assistance. Xinlan’s technical department is available 24 hours a day to provide assistance. We can help you identify the cause of the problem and provide the necessary repairs.
