The Critical Role of Hydraulic Filters
Hydraulic oil is the lifeblood of systems—filter performance dictates operational stability and safety. As the first defense line, filters block contaminants (dust, metal debris) to protect pumps and critical components.
1. Suction Filters
Function: Installed at pump inlets with low-resistance materials (corrugated metal mesh/wire rope).
Design: Large surface area + macro-pores ensure smooth flow, prevent cavitation.
Applications: High-vibration equipment (excavators, cranes) in harsh environments (mining, chemical plants).
2. High-Pressure Filters
Function: Withstand pressure surges using stainless steel sintered mesh or composite cores.
Structure: Complex assemblies (housing, head) to shield valves/actuators from failure.
Mission: Ensure precision component longevity and system reliability.
3. Selection Pitfalls & Best Practices
Myth: Prioritizing filtration precision over material strength and contaminant-holding capacity in extreme conditions.
Reality:
Pro Tip: Monitor filter status regularly to avoid oil degradation or system breakdowns.
