Hydraulic Cylinder Won't Hold Pressure at Ralph Mcbride blog

Hydraulic Cylinder Won't Hold Pressure. While a leaking piston seal can be the root cause of cylinder drift, the physics involved are often misunderstood. As pressure starts to equalize across the piston seal and the increasing static pressure on the piston side of the cylinder reaches the cracking pressure of the port relief, the cylinder will creep down. Check the cause of the failure of the hydraulic pump and main hydraulic valve and resolve it. Fact is, if the piston seal is. Learn why this happens, and how to prevent it. Gradual or sudden loss of pressure or flow resulting in a loss of power is common in hydraulic system failure. If oil is entering the cylinder, verify. The issue is likely hydraulic cylinder drift. While oil leaks aren’t always attributed to drift, they can be a culprit you always need to address. Is your hydraulic equipment jerking or not holding heavy loads? The cause (in the fluid circuit) for cylinder drift is the unbalance between areas on opposite sides of the piston.
