Hydraulic Cylinder Pressure Test Explained: How to Conduct a Cylinder Test Procedure
The cylinder pressure test, designed to test the integrity of the piston seal and welds in hydraulic cylinders, pressurizes the cylinder during operation. Once the pressure has been applied, the cylinder is inspected for signs of leakage past the seal or welded parts. This process also performs a “end-of-stroke bypass test”, and is a good indicator of the function of the hydraulic cylinder and whether a hydraulic cylinders repair is needed or has been completed correctly.
While this is a commonly used cylinder test procedure, the end-of-stroke bypass test doesn’t come without its limitations. Typically this test won’t reveal ballooning, which is better found with a piston-seal bypass test. Yet, still, it remains one of the best ways to ensure the success of your hydraulic cylinders.
To better understand the process of pressure testing a cylinder, we are breaking down more about the testing process and procedures to ensure a well-running system.
A hydraulic cylinder test stand is an apparatus that allows for operation of the cylinders under high pressure. This provides indications about the conditions within the cylinder while it is tested, reporting the results throughout the process.
The hydraulic cylinder test procedure includes several steps. Let’s break it down.
In the case the differential pressure through the piston isn’t maintained during this monitoring process, it signals that there's a problem with either the piston seal or the tube.
During this process, the ball valve shouldn’t be closed when the flow is directed to the piston side of the cylinder. This could lead to cylinder failure or personal injury. To avoid this, wear personal protective equipment for your safety.
There are several reasons why a hydraulic cylinder tester is beneficial. The benefits of a cylinder pressure test include:
With an understanding of the benefits of the cylinder pressure test, as well as knowledge of the hydraulic cylinder test procedure, it’s time to check if your cylinders are operating as they should!
