5. FAQ

Q: What integral structural design is applied to this full overhaul oil seal kit?
A: It is a complete matched multi-component combination instead of a single independent oil seal. It adopts ten-lip layered dust isolation structure, fully equipped with matched flat gaskets, assorted O-rings and rigid pressure-resistant support rings to cover all sealing positions of hydraulic pump rotary shafts.

Q: What full temperature range can this sealing assembly run stably without performance decline?
A: Its stable operating temperature range covers -148°C to 360°C, adapting to freezing alpine mine winter construction and non-stop high-temperature heavy-load operation at tropical open-pit mining yards.

Q: Can this sealing kit be universally installed on all types of construction machinery?
A: It is exclusively customized for super-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 mining work?
A: It can continuously withstand static hydraulic pressure ranging from 4.45MPa to 6.20MPa, 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?
A: It is developed for routine maintenance of main pump rotary shafts on super-large mining excavators, widely used in large open-pit mineral exploitation, mountain tunnel boring and large-scale land formation earthmoving projects.
