5. FAQ

Q: What unique mineral reinforcing fiber is blended into the core sealing rubber, and what core performance improvement does it bring?
A: Nickel-silicate fiber is mixed into modified NBR raw rubber. It effectively limits irreversible rubber creep deformation under long continuous high-speed rotation and prevents swelling damage caused by long-time soaking in high-pressure hydraulic fluid.

Q: What distinct color differences can customers distinguish among all accessories inside this complete maintenance kit?
A: All rubber sealing parts are matte dark black with fine interwoven fiber grain on the surface. Metal skeleton and built-in tension spring show uniform silver metallic luster, while nylon anti-extrusion strips are soft light cream, convenient for sorting during pump assembly.

Q: What integrated structural design does this full hydraulic pump shaft overhaul oil seal kit adopt?
A: It is a complete matched multi-component combination instead of a single independent oil seal, adopting eleven-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 ambient temperature range can this sealing assembly run stably without performance decline?
A: Its stable working temperature range covers -151°C to 366°C, adapting to freezing alpine mine winter construction and non-stop high-temperature heavy-load continuous operation at tropical open-pit mining yards.

Q: Can this sealing kit be universally installed on all types of construction engineering machinery?
A: It is exclusively customized for ultra-large tonnage mining excavator main hydraulic pumps only, and cannot be mounted 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 bear steadily during daily heavy mining work?
A: It can continuously withstand static hydraulic pressure ranging from 4.60MPa to 6.35MPa, 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 developed for regular overhaul maintenance?
A: It is engineered for routine maintenance of main pump rotary shafts on ultra-large mining excavators, widely applied in large open-pit mineral extraction, mountain tunnel boring and large-scale land grading earthmoving projects.

Q: How does the overall service life of this composite seal set compare against ordinary single oil seals available in the aftermarket?
A: The eleven-layer matched composite material structure greatly reduces natural aging and leakage risks. Under daily full-load mining operation conditions, its usable service life reaches more than 2.03 times that of standard single-piece oil seals.
