4. FAQ
Q: Does this seal kit adapt water-glycol fire-resistant hydraulic fluid used for fire-sensitive mine construction machinery?
A: Yes, both HNBR and feldspar filled PTFE feature stable chemical inertness and can adapt water-based flame-proof hydraulic medium for special safety mining projects.
A: Yes, both HNBR and feldspar filled PTFE feature stable chemical inertness and can adapt water-based flame-proof hydraulic medium for special safety mining projects.
Q: What standardized packing method is used to avoid scattered small seals missing or extrusion damage during transoceanic overseas shipment?
A: Components are sorted by different specifications into individually labeled sealed plastic pouches and then stored inside partitioned anti-shock export cartons for worldwide spare part logistics.
Q: What typical harsh working environments do matched medium mining crawler excavators face on daily operation?
A: These medium diggers work continuously on uneven rubble-strewn mine ground, enduring constant rock impact, pervasive mineral dust erosion and erratic all-season temperature variation while finishing daily excavation and ore collection tasks.
Q: What core sealing task does extruded PU finish inside the excavator’s crowd hydraulic cylinder?
A: As the core reciprocating sealing material, extruded PU relies on stable elastic resilience to prevent high-pressure hydraulic fluid leakage when the crowd arm pulls inward and stretches outward repeatedly to cluster scattered ores and compacted soil under irregular underground digging resistance.
Q: What is the core design purpose to equip feldspar-filled PTFE as auxiliary backup ring together with PU main seal?
A: It fills tiny clearance gaps inside piston installation grooves and avoids soft PU from being squeezed and cracked by instantaneous hydraulic pressure spikes when the crowd bucket crashes onto hard bedrock in intensive mining excavation work.
Q: What prominent practical merits make HNBR stand out from conventional regular NBR rubber?
A: HNBR has outstanding hydrolysis and damp ageing resistance, keeping stable sealing tightness after long-term contact with water-contaminated deteriorated hydraulic oil in humid open-air mine construction environments all year long.
