4. FAQ
Q: What composite materials are used for the core sealing components inside this pilot pump overhaul kit?
A: The main dynamic oil seals adopt camellia leaf fiber modified HNBR material. The kit is equipped with EPDM static sealing rings and PA66 backup rings to fit all sealing grooves of the pilot pump assembly.
Q: What visual features help customers distinguish different sealing accessories inside the package?
A: Fiber-reinforced HNBR oil seals are deep black with smooth matte surface; metal shells and tension springs have uniform silvery nickel plating; nylon backup rings are pale beige. All parts are free of burrs and surface flaws.
Q: What operating characteristics is this oil seal kit designed to adapt to on ultra-large excavator pilot pumps?
A: This set combines dynamic shaft sealing and static flange sealing. It prevents pilot hydraulic oil leakage and stops external pollutants from entering the pump interior during long-time continuous operation.
Q: What continuous working temperature range allows this whole sealing kit to deliver stable performance?
A: Its applicable temperature range covers -177°C to 475°C, suitable for cold mountain winter open-pit mining and uninterrupted ultra-heavy excavation work in tropical open quarry yards.
Q: Can this oil seal kit be universally used for pilot pump maintenance of all construction machinery?
A: It is dimensionally customized exclusively for ultra large crawler excavator pilot pump structures only. It cannot match motor grader hydraulic assemblies, wheel loader pumps or medium excavator swing motor sealing kits of other equipment series.
Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-term cyclic operation?
A: With support from backup rings, the sealing group can steadily sustain pressure between 7.12MPa and 7.93MPa, resisting pressure fluctuations generated during frequent pilot control actions.
Q: What typical large-scale engineering projects require this pilot pump seal kit for regular overhaul?
A: It supports routine maintenance of pilot pump sealing assemblies on ultra large crawler excavators, widely applied in large open-pit mineral extraction, coastal land reclamation, mountain tunnel construction and hydropower foundation projects.
Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals available on the market?
A: The added plant fiber filler greatly improves tensile strength and anti-aging performance. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.53 times that of conventional nitrile oil seals.
