4. FAQ

Q: What multiple composite materials are used in this charge pump housing gasket kit?
A: This kit is composed of stainless steel reinforced graphite composite gaskets, bamboo bark fiber sealing sheets, EPDM rubber washers and precision metal adjusting shims. Different materials are matched for various sealing surfaces of the charge pump housing.

Q: What visual characteristics 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 profiles.

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

Q: What continuous working temperature range can this whole gasket kit withstand steadily?
A: Its applicable temperature range covers -175°C to 469°C, suitable for cold northern plateau open-pit mining construction and uninterrupted ultra-heavy cyclic 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 charge pump housing structures only. It cannot fit road grader gearboxes, backhoe loader axles or medium excavator hydraulic valve assemblies of other equipment series.

Q: What static hydraulic pressure can these composite gaskets sustain during long-term continuous fluid circulation?
A: The matched assembly can steadily bear static pressure ranging from 7.00MPa to 7.81MPa. It maintains reliable sealing even if slight housing deformation occurs under continuous vibration loads.

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

Q: How does the service life of these composite gaskets compare with ordinary single-layer fiber paper gaskets available on the spare parts market?
A: The reinforced composite structure significantly improves creep resistance and hydraulic medium corrosion resistance. Under continuous cyclic working conditions, its service life reaches more than 3.47 times that of standard fiber paper gaskets.

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.
