Inspecting Hydraulics: Pumps, Cylinders, and Lines
-
Hydraulic Pumps:
- Visual Inspection: Check for leaks, cracks, or signs of wear on the pump housing.
- Performance Testing: Measure pump output pressure using a gauge. Compare it to the manufacturer’s specifications.
- Noise: Listen for unusual noises during operation, which could indicate internal damage.
-
Hydraulic Cylinders:
- External Inspection: Examine cylinder rods, seals, and mounting points.
- Seal Condition: Look for oil leaks around cylinder seals.
- Stroke Smoothness: Operate the cylinder through its full range to ensure smooth movement.
- Scored Rods: Any gashes or uneven parts of a rod will damage the internal seals over time.
- Bent Rods: Inspect for bent or damaged cylinder rods.
-
Hydraulic Lines:
- Leaks: Inspect all hydraulic lines for leaks. Pay attention to connections, fittings, and hoses.
- Corrosion: Check for rust or corrosion on metal lines.
- Rubber Hoses: Look for cracks, bulges, or signs of aging in rubber hoses.
- Routing: Ensure proper routing to prevent kinks or pinching.
