Preventing Hydraulic Oil Contamination in Metal Shears
Install high-efficiency filters (10-15 micron) at multiple circuit points to trap particles.
• Regular filter inspection/replacement
• Periodic oil sampling and analysis
• Multi-point filtration (suction/pressure/return lines)
• Timely oil changes based on condition
Maintain tight seals on all components and control the operating environment.
• Use wear-resistant seals on cylinders/valves
• Enclose hydraulic systems when possible
• Install desiccant breathers on reservoirs
• Maintain clean operating areas
Ensure clean procedures for oil transfer and proper storage conditions.
• Use dedicated, clean transfer equipment
• Store oil in sealed containers
• Maintain dry, dust-free storage areas
• Verify oil cleanliness before use
Control oil temperature and monitor fluid properties to prevent degradation.
• Maintain oil at 40-60°C with heat exchangers
• Check cooler efficiency regularly
• Monitor viscosity and acid number
• Prevent oil oxidation and sludge formation
Educate staff and implement proactive maintenance routines.
• Train operators to recognize contamination signs
• Conduct routine visual inspections
• Clean reservoir internals periodically
• Address leaks and worn parts immediately
