How To Check If Hydraulic Cylinder Is Leaking Internally?

Checking for internal leaks in a hydraulic cylinder is an important maintenance task to ensure proper functioning and prevent potential issues. Here’s a step-by-step guide on how to check if a hydraulic cylinder is leaking internally:

1. Safety First: Before performing any maintenance tasks, ensure that the hydraulic system is depressurized and that all power sources are disconnected to avoid accidents.
2. Visual Inspection: Begin by visually inspecting the exterior of the hydraulic cylinder for any signs of oil leaks. Look for oil stains, drips, or wet spots around the cylinder body, rod, and seals. External leaks may indicate internal leaks as well.
3. Cylinder Retraction: Extend the hydraulic cylinder fully and then retract it completely. Observe if there are any noticeable changes in speed or resistance during extension or retraction. Unusual slow or jerky movement can be a sign of internal leakage.
4. Hold Position: Extend the cylinder to a specific position and keep it set for a while, such as several minutes to an hour. Monitor if the cylinder maintains its position without drifting. Drifting or gradual movement indicates internal leakage.
5. Cylinder Drift Test: Perform a cylinder drift test by fully extending the cylinder and closing the control valve to isolate the cylinder from the hydraulic system. Monitor the cylinder’s position over an extended period, such as several hours, to check for movement. If the cylinder drifts or moves slowly, it suggests internal leakage.
6. Pressure Drop Test: Connect a pressure gauge to the hydraulic system and pressurize it to the maximum working pressure. Close the control valve to isolate the cylinder. Monitor the pressure gauge for any significant pressure drop over time. A rapid pressure drop indicates internal leakage.
7. Disassembly and Inspection: If you suspect an internal leak but haven’t identified it through previous tests, you may need to disassemble the hydraulic cylinder for a more thorough inspection. Consult the manufacturer’s guidelines or seek assistance from a qualified technician to ensure proper disassembly and reassembly.
8. Seal Examination: Inspect the cylinder’s seals, including the piston seal, rod seal, and gland seals, for any signs of damage, wear, or deterioration. Damaged or worn seals can cause internal leaks. Replace any faulty seals with suitable replacements.
9. Reassembly and Testing: After completing the necessary inspections or repairs, reassemble the hydraulic cylinder and conduct a final operational test. Perform the previous tests mentioned above to ensure that the internal leaks have been resolved and the cylinder functions properly.
