Kev tsis
Crankshaft roj foob yog cov khoom sib khi nruab rau ntawm lub hauv ntej thiab nram qab kawg ntawm lub cav crankshaft. Nws yog siv los tiv thaiv cov roj lubricating los ntawm kev tawm ntawm lub hauv ntej thiab nram qab kawg ntawm lub crankshaft, thiab tiv thaiv cov plua plav sab nraud thiab impurities nkag mus rau hauv lub cav sab hauv. Nws feem ntau muaj cov khoom siv roj hmab thiab cov khoom siv hlau.
- Sealing muaj nuj nqi: Lub luag haujlwm tseem ceeb ntawm crankshaft roj foob yog los xyuas kom meej lub cev ua haujlwm ntawm lub cav hauv lub tshuab lubrication thiab tiv thaiv cov roj lubricating. Nws tsim ib lub foob los ntawm kev hu rau lub crankshaft nto, tiv thaiv cov roj lubricating los ntawm cov ntaub ntawv crankshaft.
- Hnav tsis kam: Lub crankshaft roj foob yuav tsum tau tiv thaiv kev sib txhuam thiab siab ntawm kev kub ceev rotating crankshaft nto. Yog li ntawd, nws feem ntau siv cov khoom siv roj hmab hnav-resistant xws li styrene-butadiene roj hmab (NBR) lossis fluorine roj hmab (FKM) los muab kev pabcuam ntev.
- Kub-resistant: Crankshaft roj ntsaws ruaj ruaj yuav tsum tau ua hauj lwm nyob rau hauv high kub ib puag ncig vim hais tias cov roj lubricating ntawm crankshaft phau ntawv journal feem ntau cuam tshuam los ntawm qhov kub thiab txias. Yog li ntawd, cov khoom ntawm crankshaft roj foob yuav tsum muaj qhov kub thiab txias tiv thaiv kom tsis txhob muaj cov khoom laus thiab tsis ua haujlwm.
- Elasticity thiab nruj: Lub crankshaft roj foob yuav tsum muaj qee yam ntawm elasticity kom hloov mus rau kev sib hloov thiab deformation ntawm crankshaft. Nws yuav tsum haum snugly tiv thaiv lub crankshaft nto los xyuas kom meej ib tug zoo foob.
- Tshuaj tiv thaiv: Crankshaft roj foob yuav tsum tiv thaiv los ntawm lubricants thiab lwm yam tshuaj. Yog li ntawd, nws feem ntau yog ua los ntawm cov khoom siv roj hmab nrog cov tshuaj lom neeg zoo.
- Yooj yim ntawm installation thiab txij nkawm: Crankshaft roj foob feem ntau yog tsim los kom yooj yim rau nruab thiab tswj kom yooj yim hloov thiab kho.
