Hydraulic cylinders are extremely useful tools when they are functioning properly, helping drive machinery and provide the force needed. However, when air enters the equation, the cylinder may no longer work as efficiently. The following process will help you bleed the air from your single acting hydraulic cylinder to improve its performance.
Bring the Air to the Top
First and foremost, it’s important to bring the air to the top of the cylinder so it can be released more effectively. In order to do so, you will need to open up the single acting hydraulic cylinder to its full extension and leave it extended for several minutes to allow the air to naturally rise to the top. This may take some time depending on the amount of air.
Releasing the Air
After you have brought all the air to the top of the single acting hydraulic cylinder, you will need to close it but not completely. Once you have partially closed the cylinder, you can open the bleed valve at the top, providing an escape for the air that has become trapped inside. Leave this valve open until hydraulic fluid flows from the valve, indicating the air has been fully released. You can then close the valve and continue operating the single acting hydraulic cylinder normally.
Keeping your hydraulic cylinders in great shape is part of ensuring your machinery continues to operate as it was intended. No matter whether you have a new single acting hydraulic cylinder or you’ve been using it for awhile, chances are you will need to know how to bleed the air out on occasion to improve efficiency.
