Cov roj yog ib qho tseem ceeb hauv kev lag luam niaj hnub no. Lawv yog siv rau machining chassis, chains, axis teb nyob rau hauv cov khoom, rau li qub thiab ntau lwm yam kev siv.

Lawv siv tau tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas tshwm sim los ntawm kev hloov pauv kub thiab av noo siab.

Ntse thiab cov khoom ntawm roj

Cov nyiaj no muaj cov yas. Qhov no yog qhov sib txawv tseem ceeb ntawm lawv thiab cov kua roj lubricants. Lawv yog tsim los ntawm cov roj nrog ntxiv cov thickeners, uas yuav siv tau raws li polymers, av nplaum, carboxylic ntsev.

• Greases muaj xim sib txawv. Lawv yog pob tshab, dub, lub teeb xim av.
• Ntau yam ntawm cov khoom no muab kev tiv thaiv corrosion rau machined qhov chaw.
• Tshuaj tsis hnov tsw.
• Tsis txhob hloov lawv qhov ntom nrog qhov kub thiab txias.
• Cov roj nplua nyeem tsis khiav, uas ua rau lawv yooj yim siv.
• Lub sijhawm hloov pauv tsawg kawg yog 2 txog 4 lub lis piam. Ces tus neeg sawv cev yuav tsum tau hloov.

Greases:hom

Hnub no, muaj ntau hom roj. Wb tham txog lub ntsiab.

1. Sodium. Lawv feem ntau ntxiv nrog calcium. Lwm lub npe yog qhov tsis tu ncua. Nws yog advisable siv lawv nyob rau hauv tej yam kev mob nrog kub ntawm 70 mus rau 110 degrees. Qhov tsis zoo yog qhov uas lawv ntshai dej thiab tuaj yeem yaj hauv nws.
2. Lithium. Ua nrog lithium. Lawv yog cov tshwj xeeb tshaj yog zoo nyob rau hauv tej yam kev mob uas muaj zog vibration, nyob rau hauv hnyav loads. Zoo rau kev siv mus sij hawm ntev.
3. Aluminium. Ua los ntawm aluminium. Resistant mus rau ya raws, tiv thaiv oxidation ntawm hlau, yog li nce conductivity. Feem ntau siv nyob rau hauv tej yam kev mob tshwm sim los ntawm siab kub.
4. Polyurethane. Ua los ntawm cov hmoov nplej. Lawv yooj yim rau biodegradation. Tsis txhob muaj kev phom sij rau ib puag ncig thiab tib neeg lub cev.
5. Teflon. Lawv txawv los ntawm kev ua kom sov zoo, lawv tuaj yeem tiv taus kub txog 250 degrees. Ib hom yeeb yaj kiab tau tso rau ntawm qhov chaw ua tiav, uas muaj hluav taws xob insulating thiab dej-repellent zog.
6. Polyglycol. Lawv siv tso cai rau koj mus cuag lub neej ntawm cov mechanisms. Tshwj xeeb yog siv nyob rau hauv qhov kub thiab txias.
7. Silicon. Tiv thaiv corrosion. Tsim ib zaj duab xis nrog dej-repellent zog. Txhim kho zawv zawg, yog li tiv thaiv kev sib txhuam ntawm qhov chaw. Yuav tsis ntxuav nrog dej.

Ntxiv rau cov hom tseem ceeb no, muaj ntau yam ntxiv: pastes, greases raws li thickeners (ob qho tib si organic thiab inorganic), thiab lwm yam..

Cov khoom siv

Greases muaj ntau yam kev siv. Yog li, piv txwv li, silicone yog siv rau cov tub yees. Lawv yog cov zaub mov pom zoo. Cov roj nplua nyeem zoo li no muaj nyob hauv lub neej txhua hnub. Lawv ua cov xim pleev xim ntawm lub cev lub tsheb, lubricate lub xauv thiab qhov rooj hinges.

Konstalins yog siv rau txhua hom kev sib kis ntawm cov tshuab - shafts thiab rollers. Tsis tas li ntawd, lawv yog cov kuab tshuaj zoo rau cov kua roj vanish.

Lithium roj feem ntau yog siv rau qhov chaw ntawm cov khoom siv. Nws yog qhov zoo heev rau cov bearings thiab cov menyuam bearings.

Raws li koj tuaj yeem pom, roj muaj ntau yam khoom muaj txiaj ntsig uas tiv thaiv cov khoom siv thaum lub sijhawm tsim khoom.
