4. FAQ

Q: What different composite materials are adopted inside this main pump housing gasket kit?
A: This kit contains stainless steel reinforced graphite composite gaskets, camphor leaf fiber sealing sheets, HNBR rubber washers and precision metal adjusting shims. Multiple materials are matched for different sealing surfaces on the main pump housing.

Q: What visual features help customers distinguish various sealing accessories inside the package?
A: Metal composite gaskets are silver gray with graphite surface; fiber gaskets are light brown; rubber washers are matte black; adjusting shims are bright silver metal plates. All components are pre-cut according to original equipment outline.

Q: What sealing objectives is this gasket kit designed to achieve for ultra-large excavator main pump assemblies?
A: It focuses on static joint sealing of main pump housings and end covers. Multi-material collocation adapts to varied pressure and temperature conditions to stop hydraulic oil leakage on split mating surfaces.

Q: What continuous working temperature range can this whole gasket kit operate reliably?
A: Its applicable temperature range covers -174°C to 466°C, suitable for cold northern plateau open-pit mining and uninterrupted ultra-heavy excavation work at tropical quarry yards.

Q: Can this gasket kit be universally used for pump overhaul of all construction machinery?
A: It is dimensionally customized exclusively for ultra large crawler excavator main pump housing structures only. It cannot fit road grader gearboxes, backhoe loader axles or medium excavator valve assemblies of other machine series.

Q: What static hydraulic pressure can these composite gaskets sustain during long-term operation?
A: The matched assembly can steadily withstand static pressure ranging from 6.94MPa to 7.75MPa. It maintains tight sealing even if slight housing deformation occurs under ultra-heavy working loads.

Q: What large-scale engineering projects require this main pump gasket kit for regular maintenance?
A: It serves routine overhaul of main pump housing sealing assemblies on ultra large crawler excavators, widely applied in super large open-pit mineral exploitation, coastal land reclamation, long tunnel construction and large dam foundation development projects.

Q: How does the service life of these composite gaskets compare with ordinary single-layer fiber paper gaskets?
A: The reinforced composite structure greatly improves creep resistance and hydraulic oil corrosion resistance. Under continuous heavy cyclic working conditions, its service life reaches more than 3.44 times that of standard fiber paper gaskets.

Q: How well can these gaskets adapt to minor unevenness on assembly flanges?
A: Graphite and fiber layers possess favorable compressibility. They can fill tiny gaps on mating surfaces and effectively prevent hydraulic oil seepage caused by minor surface imperfections of pump housings.

Q: How does the service life of these composite gaskets compare with ordinary fiber paper gaskets available on the spare parts market?
A: The reinforced composite structure improves creep resistance and medium corrosion resistance significantly. Under long-cycle heavy-duty working conditions, its service life reaches more than 3.43 times that of standard single-layer fiber paper gaskets.

Q: How does the service cycle of sisal stalk fiber reinforced HNBR composite seal set compare with ordinary single oil seals sold in aftermarket stores?
A: The sisal stalk fiber doping formula greatly improves compression recovery, low-temperature elasticity and high-pressure durability. Under daily continuous heavy compound excavation working conditions, its usable service life reaches more than 3.24 times that of standard single-piece oil seals.
