stripping qhov ntev yog raws li qhia los ntawm daim duab (Fig2), yuav tsum tau them nyiaj mloog thaum stripping:
1. Qhov kawg nto ntawm tus neeg xyuas pib sab hauv yuav tsum tau chamfered.
2. Tshem tawm cov impurities xws li tooj liab nplai thiab burr ntawm qhov kawg ntawm lub cable.
Sib dhos qhov sib khi: Screw lub sealing ib feem nyob rau hauv raws li tus neeg xyuas pib ntawm lub cable raws li qhia los ntawm daim duab (Fig3).
Sib sau cov txiv ntoo qab (Fig 3).
Muab cov txiv ntseej rau pem hauv ntej thiab nraub qaum los ntawm screwing raws li qhia hauv daim duab (Figs(5)
1. Ua ntej screwing, smear ib txheej ntawm lubricating roj ntawm lub o-ring.
2. Khaws lub nraub qaum thiab lub cable tsis txav, ntsia hlau rau ntawm lub plhaub tseem ceeb ntawm lub plhaub sab nraub qaum.Screw lub plhaub tseem ceeb ntawm lub plhaub rov qab lub cev siv lub dab teg liab.Kev sib dhos tiav lawm.
