Nta txhim khu kev qha kev tiv thaiv: greases

Greases yog ib qho tseem ceeb nyob rau hauv niaj hnub kev lag luam. Lawv yuav siv los tuav chassis circuits, teb axes nyob rau hauv cov khoom rau li qub thiab muaj ntau yam lwm yam zaus. Tshwj xeeb tshaj yog zoo yog lawv siv nyob rau hauv tej yam kev mob uas txawv txawv heev kub thiab high av noo.

Nta thiab cov yam ntxwv ntawm lubricating greases

Cov kab mob muaj ductility. Qhov no yog lub ntsiab qhov txawv nruab nrab ntawm lawv los ntawm cov kua lubricants. Lawv yog raws li nyob rau hauv roj nrog rau qhov sib ntxiv ntawm thickeners, raws li tej zaum yuav siv polymers, av nplaum, carboxylic ntsev.

• Greases muaj ib tug txawv xim. Lawv yog cov pob tshab, dub, lub teeb xim av.
• Muaj ntau ntawm cov cuab yeej muab xeb tiv thaiv workpiece.
• Yus muaj los ntawm ib tug tsis muaj tsis hnov tsw.
• Tsis txhob hloov lawv ceev raws li qhov kub thiab txias hloov.
• Tej lubricants tsis ntws, uas ua rau lawv yooj yim rau siv.
• Qhov tsawg kawg nkaus lub sij hawm ntawm kev ua hauj lwm mas nws txawv ntawm 2 mus rau 4 lub lis piam. Ces koj yuav tsum tau hloov lub cuab tam.

Greases: Hom

Rau hnub tim, muaj ntau li ntau ntau ntau yam ntawm greases. Cia tus tham txog lub ntsiab sawv daws yuav.

1. Sodium. Feem ntau nrog qhov sib ntxiv ntawm calcium. Lwm lub npe - Konstalin. Nws yog tsim nyog yuav tau mus thov nyob rau hauv tej yam kev mob ntawm kub ntawm 70 mus 110 degrees. Lub downside yuav hu ua lub fact tias lawv yog cov ntshai dej thiab yuav ua neej nyob rau hauv nws.
2. Lithium. Ua rau lub hauv paus ntawm lithium. Lawv yog tshwj xeeb yog zoo nyob rau hauv chaw uas muaj muaj zog co nyob rau high school loads. Tag nrho rau cov sij hawm ntev siv.
3. Aluminium. Ua rau lub hauv paus ntawm txhuas. Resistant rau dej, los mus tiv thaiv oxidation ntawm lub co tshaj zog conductivity. Nws yog feem ntau siv nyob rau hauv ib qho chaw yus muaj los ntawm txhawb kub.
4. Polyurethane. Nws yog raws li nyob rau hauv cov hmoov. Lawv yuav tsum biodegradable. Tsis txhob muaj tej teeb meem los rau cov ib puag ncig thiab tib neeg lub cev.
5. Teflon. Lawv txawv los ntawm ib tug zoo thaum tshav kub kub kuj, lawv muaj peev xwm mas kub txog li 250 degrees. Nyob rau workpieces tawm tus thawj zaj duab xis muaj hluav taws xob insulating thiab dej-repellent zog.
6. Polyglycol. Lawv siv tso cai rau kom ntev lub neej ntawm machinery. Tshwj xeeb yog feem ntau siv nyob rau hauv tej yam kev mob uas muaj kub.
7. Roj hmab. Tiv thaiv tiv thaiv corrosion. Tsim ib zaj duab xis muaj dej repellency. Glidants, li no tiv thaiv fouling ntawm Cheebtsam. Tsis txhob yaug nrog dej.

Nyob rau hauv tas li ntawd mus rau cov theem pib hom tshwm sim thiab ntau lwm tus neeg: ib tug muab tshuaj txhuam, roj thickeners raws li (ob organic thiab inorganic), thiab lwm yam ...

Cov cheeb tsam ntawm kev siv ntawm cov khoom

Greases yog txaus thoob plaws cheeb tsam ntawm kev siv. Piv txwv li, silicone yog siv rau hauv tub yees. Lawv muaj ib tug khoom noj khoom haus nyiaj. Tej qho roj nplua nyeem thiab nyob rau hauv tsev. Lawv kho paintwork tsheb lub cev, ntub lub xauv thiab hinges.

Konstalin siv rau tag nrho cov hom ntawm zog - shafts thiab chais. Nyob rau hauv tas li ntawd, lawv yog ib tug zoo kuab rau cov xim tsev.

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

Raws li koj tau pom, lub roj muaj ib tug txheej ntawm pab nta uas tiv thaiv tus neeg kho tshuab qhov chaw nyob rau hauv cov txheej txheem.
