How should you prepare a hydraulic cylinder before use?

The following is a detailed description of the preparatory work required before using a hydraulic cylinder:

1. Inspection

Leak Test: Check for oil leaks at the cylinder piston rod, hydraulic hose fittings, and valve assembly connections; verify seal integrity through a pressure test.

Component Integrity: Confirm that the cylinder body has no cracks or deformation and that bolts are securely fastened; ensure that power units such as hydraulic pumps and motors are operating normally.

Lubrication and Maintenance: Apply lubricant to mechanical friction points such as guide rails and pins to reduce wear during operation.

2. Safety Measures

Site Clearance: Remove debris from around the equipment to ensure sufficient operating space and a dry, non-slip floor.

Personal Protective Equipment: Wear safety shoes and gloves; tie back long hair to prevent entanglement in moving parts.

Emergency Preparedness: Familiarize yourself with the location of the emergency stop button and conduct regular drills on the pressure relief procedure.

3. Parameter Calibration

Pressure Setting: Adjust the system operating pressure according to process requirements, ensuring it does not exceed the rated value via the relief valve.

Stroke Adjustment: Set the extension and retraction limits of the hydraulic cylinder to prevent mechanical damage caused by overtravel.

After completing the above preparations, it is recommended to conduct a no-load test run to verify the condition of the hydraulic cylinder, providing a double safeguard for formal commissioning.
