5. FAQ

Q: What composite mineral fiber is infused into the core sealing rubber, and what performance advantage does it deliver?
A: Boron-nickel silicate fiber is blended into modified NBR base rubber. It effectively inhibits permanent rubber creep deformation under non-stop high-speed rotation and prevents swelling damage after long-term immersion in high-pressure hydraulic medium.

Q: What obvious color distinctions can clients observe among all accessories inside this full overhaul maintenance kit?
A: All rubber sealing components are matte charcoal black with delicate interlaced fiber grain on the surface. Metal skeleton and built-in tension spring carry uniform silver metallic luster, while nylon anti-extrusion strips are soft pale off-white for easy classification during pump assembly.

Q: What overall integrated structural layout does this full hydraulic pump shaft oil seal kit adopt?
A: It is a complete matched multi-component assembly instead of a single standalone oil seal, featuring twelve-layer lip dust and oil mist isolation design, fully equipped with matched flat gaskets, assorted multi-size O-rings and rigid pressure-resistant support rings to cover all sealing positions of hydraulic pump rotary shafts.

Q: What full span of ambient temperatures can this sealing assembly run stably without performance attenuation?
A: Its stable working temperature range spans -152°C to 368°C, adapting to freezing alpine mine winter construction and uninterrupted high-temperature heavy-load continuous operation at tropical open-pit mining yards.

Q: Is this sealing kit compatible with all types of construction engineering machinery universally?
A: It is tailor-made exclusively for ultra-large tonnage mining excavator main hydraulic pumps only, and cannot be installed on wheel loaders, road graders or medium and small-sized digging machines of other series.

Q: What long-term static hydraulic pressure can the whole sealing assembly withstand steadily during daily heavy mining construction work?
A: It can continuously bear static hydraulic pressure ranging from 4.65MPa to 6.40MPa, and buffer instantaneous pressure surges triggered by equipment cold startup and frequent heavy load switching to avoid slow persistent hydraulic oil seepage.

Q: What core engineering construction scenarios is this sealing kit designed for regular overhaul maintenance work?
A: It is developed for routine maintenance of main pump rotary shafts on ultra-large mining excavators, widely applied in large open-pit mineral exploitation, mountain tunnel boring and large-scale land formation earthmoving projects.

Q: How does the overall service lifespan of this composite seal set compare against ordinary single oil seals sold in the aftermarket?
A: The twelve-layer matched composite material structure greatly lowers natural aging and leakage risks. Under daily full-load mining operation conditions, its usable service life reaches more than 2.06 times that of standard single-piece oil seals.
