4. FAQ

Q: What composite materials are assembled inside this lubrication pump housing gasket kit?
A: This kit contains carbon steel reinforced graphite composite gaskets, pagoda leaf fiber sealing sheets, EPDM rubber washers and precision stainless steel adjusting shims. Different materials are matched for various static sealing surfaces of the lubrication pump housing assembly.

Q: What visual cues help customers quickly distinguish different sealing accessories inside the package?
A: Steel composite gaskets are silver gray with graphite surface; fiber gaskets are light beige; rubber washers are matte black; adjusting shims are bright silver metal plates. All components are pre-cut strictly according to original housing outlines.

Q: What sealing targets is this gasket kit designed to achieve for medium crawler excavator lubrication pump assemblies?
A: It focuses on static joint sealing of lubrication pump housings and end covers. Multi-material collocation adapts to varying pressure and temperature to prevent lube oil leakage on split mating surfaces.

Q: What continuous working temperature range allows this whole gasket kit to operate steadily?
A: Its applicable temperature range covers -161°C to 444°C, suitable for cold region winter infrastructure construction and continuous medium-load excavation work at tropical open quarries.

Q: Can this gasket kit be universally used for lubrication system overhaul of all construction machinery?
A: It is dimensionally customized exclusively for medium crawler excavator lubrication pump housing structures only. It cannot fit motor grader engine assemblies, wheel loader gearboxes or large excavator hydraulic valve housings of other machine series.

Q: What static working pressure can these composite gaskets withstand during long-term circulating lubrication operation?
A: The matched assembly can steadily sustain static pressure ranging from 6.30MPa to 7.10MPa. It maintains tight sealing even if slight housing deformation occurs under long-term engine vibration.

Q: What typical engineering projects require this lubrication pump gasket kit for regular maintenance?
A: It serves routine overhaul of lubrication pump housing sealing assemblies on medium crawler excavators, widely applied in urban pipeline laying, highway subgrade construction, small open-pit mining and residential 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 pagoda leaf fiber reinforced composite structure greatly improves creep resistance and lubricant corrosion resistance. Under cyclic vibration working conditions, its service life reaches more than 3.12 times that of standard fiber paper gaskets.

Q: How effectively can these gaskets adapt to minor surface unevenness on assembly flanges?
A: Graphite and fiber layers have good compressibility. They can fill tiny gaps on mating surfaces and effectively block lube oil seepage caused by minor machining defects of pump housings.
