How To Test A Hydraulic Cylinder?
In a previous post, I described the danger associated with the intensification of pressure in a double-acting hydraulic cylinder. In this post, I will explain how to use the intensification effect to test the integrity of the piston seal in a double-acting hydraulic cylinder. But before attempting this test procedure, it is absolutely essential that the danger associated with pressure intensification in a hydraulic cylinder is fully understood. Therefore, read this article FIRST!
The conventional way of testing the integrity of the piston seal in a double-acting cylinder is to pressurize the cylinder at the end of stroke and measure any leakage past the seal. This is commonly referred to as the "end-of-stroke bypass test".
