5. FAQ
Q: What full-spec integrated matching structure does this main pump O-ring set adopt for large wheel loaders?
A: It is a complete multi-size matched assembly instead of scattered single-size O-rings, covering all standard circular seals, anti-extrusion support rings and thin shims required for main pump valve body, piston and oil port sealing positions.
A: It is a complete multi-size matched assembly instead of scattered single-size O-rings, covering all standard circular seals, anti-extrusion support rings and thin shims required for main pump valve body, piston and oil port sealing positions.
Q: What full stable operating temperature range can this whole set of sealing components maintain reliable sealing performance?
A: Its applicable temperature range is -152°C to 395°C, suitable for frigid northern winter mining operations and continuous heavy-load loading work under high-temperature open-air construction environments.
Q: Can this O-ring assembly be universally installed on hydraulic systems of all construction machinery models?
A: It is custom-sized and formula tailored exclusively for large wheel loader main pump assemblies only, and cannot fit road grader hydraulic cylinders, excavator swing motors or crawler bulldozer final drive housings.
Q: What peak instantaneous hydraulic pressure can the matched combination of O-rings and PTFE rings withstand without extrusion failure?
A: This composite matching structure can resist instantaneous hydraulic pressure up to 6.7MPa, buffer sharp pressure surges from frequent loader bucket lifting and lowering, and prevent gradual hydraulic oil seepage.
Q: What core construction and mining projects rely on this O-ring kit for regular hydraulic system overhaul?
A: It is designed for routine maintenance of main pump rotary parts on large wheel loaders, widely applied in open-pit mineral mining, aggregate stockyard handling, port cargo stacking and large infrastructure earthmoving projects.
Q: How does the service cycle of graphite modified FKM O-rings compare with ordinary unmodified rubber sealing rings?
A: The graphite doping formula greatly improves high temperature resistance, anti-aging and anti-extrusion performance. Under daily full-load heavy loading conditions, its service cycle reaches 2.6 times that of standard pure rubber O-rings.
Q: Can this set of sealing rings block mine mud, rock dust and suspended hot hydraulic oil mist in harsh long-term outdoor mining working conditions?
A: The dense smooth fluororubber surface isolates tiny sediment and hot oil mist from penetrating pump assembly gaps, and wear-resistant PTFE back rings avoid friction damage mixed with hard mineral dust inside pump cavities.
Q: What practical labor-saving advantages can field maintenance technicians gain from using this fully pre-matched all-in-one O-ring kit?
A: All commonly used specifications required for main pump overhaul are pre-assembled in one set without separate ordering. Maintenance staff do not need to carry scattered loose seals or repeatedly measure dimensions on site, significantly shortening pump repair duration.
