Custom Hydraulic Cylinders for Diverse Industrial Applications

Mining oil cylinder oil leak reason?

External Leakage

1: Seal damage at piston rod end: Caused by rod bending, surface damage, cylinder head deformation, groove rust, or aging.

2: Seal damage between rod extension and cylinder block: Due to excessive force during cylinder head installation or cylinder mouth deformation.

3: Leakage from cracked oil inlet/outlet pipe joints.

Leakage from defects in cylinder barrel/cylinder head.

4: Seal aging from deteriorated hydraulic oil or abnormal system temperature rise.

5:Result of unreasonable design or cost-cutting.

Internal Leakage

1:Severe wear of piston wear rings: Causes friction, scuffing cylinder barrel, piston, and seals.

2:Piston seal failure/aging from long-term use.

3:Contaminated hydraulic oil: Impurities (iron filings/foreign objects) wear piston seals.

Industrial Oil Cylinder

Tube: Skived, burnished or vertical honed tube ensures the concentricity and surface finish of the product.

Eye: All eyes are made of forged high-strength steel, which guarantees the product's appearance and mechanical performance.

Rod Seal: Superior quality well-known brand seals extend service life and enhance sealing effect. It adopts polyurethane U-packing rod seals, buffer seals combined with bonded-to-metal wiper seals. Custom seals are available.

Bushing: Hardened steel bushing or copper bushing.

Cap: All caps are made of forged high-strength steel.

Rod:The piston rod undergoes quenching and tempering as well as induction hardening to enhance its strength and toughness. Subsequent surface electroplating improves its corrosion resistance and scratch resistance.

Precautions for Hydraulic Cylinder Use

1: Protect the piston rod’s outer surface from collisions/scratches; regularly clean sediment on wiper rings and exposed rods to prevent contamination.

2: Inspect threaded connections/bolts periodically and tighten loose parts promptly to avoid oil leakage.

3: Lubricate joints regularly to prevent rust/abnormal wear; address rusted areas timely.

4: Replace hydraulic oil and clean filters periodically to maintain oil cleanliness.

5: Control system temperature to avoid seal aging/deformation from overheating.

6: Perform 3-5 full-stroke test runs before each use to exhaust air and preheat systems.
