Ib qho kev piav qhia ntxaws txog cov hom kev coj tus kheej uas raug cais los ntawm cov yam ntxwv siv
Ib qho kev piav qhia ntxaws ntxaws txogkev coj uahom kev faib tawm los ntawm kev siv cov yam ntxwv
Raws li qhov chaw ua haujlwm sib txawv thiab kev siv cov kev xav tau, cov bearings tuaj yeem muab faib ua pawg hauv qab no:cov kabmob kub siab, cov kabmob kub qis, cov kabmob tiv taus corrosion, cov kabmob sulfur-resistant, cov kabmob tiv thaiv magnetic, cov kabmob nqus tsev, cov kabmob self-lubricating, cov kabmob ceramic thiab cov kabmob ceev ceev.
Nws yog qhov tsim nyog rau cov ntawv thov nrog qhov kub ua haujlwm tshaj 120 ° C, thiab siv dav hauv cov cav aerojet, atomic reactors, X-ray raj, cov khoom siv semiconductor manufacturing, thiab cov khoom siv yaj, txheej thiab electroplating.
Tsim los rau qhov kub qis heev hauv qab -60 ° C, xws li cov twj tso kua LNG, cov twj tso kua nitrogen/hydrogen, cov twj tso kua butane, cov khoom siv roj hauv lub dav hlau thiab cov foob pob. Cov qauv feem ntau yog cov kabmob sib sib zog nqus ib kab thiab cov kabmob cylindrical roller.
3. Cov kabmob uas tiv taus xeb
Nws yog siv rau hauv cov av noo lossis corrosive media, xws li dej hiav txwv, pa thiab acid-alkali ib puag ncig. Nws yog feem ntau ua los ntawm cov khoom siv stainless hlau (xws li 9Cr18 thiab 9Cr18Mo), thiab lub tawb feem ntau yog ua los ntawm 0Cr19Ni9 lossis beryllium bronze; Cov hlau tsis xeb kub siab xws li Cr14Mo4 yog siv rau hauv cov chaw kub siab; Rau cov bearings loj, cov hlau tsis xeb martensitic (xws li 1Cr13 thiab 2Cr13) feem ntau yog ua los ntawm kev kho nitriding saum npoo.
4. Cov kabmob uas tiv taus cov sulfur
Rau cov hydrogen sulfide (H? S) ntawm cov pa roj hnyav. Cov hlau bearing yooj yim ua tsis tiav vim yog hydrogen embrittlement lossis electrochemical corrosion, yog li nws yog qhov tsim nyog siv cov khoom siv tshwj xeeb ua los ntawm nickel-chromium alloys xws li 00Cr40Ni55A13, tab sis nws qhov nyuaj (51 ~ 55HRC) qis dua me ntsis, lub peev xwm bearing tsawg, thiab yuav tsum tau them sai sai rau qhov kev ncaj ncees ntawm qhov chaw thaum siv.
5. Cov kabmob tiv thaiv hlau nplaum
Ua los ntawm cov khoom siv tsis muaj hlau nplaum, nws muaj qhov permeability qis heev thiab tsim nyog rau kev siv hauv cov chaw muaj zog magnetic. Beryllium bronze (QBe2) yog cov khoom siv feem ntau nrog lub zog zoo heev, elasticity, hnav tsis kam thiab corrosion tsis kam, thiab siv dav hauv huab cua, dej hiav txwv thiab lwm yam ib puag ncig.
6. Lub tshuab nqus tsev
Nws yog siv rau hauv qhov chaw nqus tsev siab (qhov nqus tsev siab dua 1.33Pa), thiab feem ntau siv rau hauv cov khoom siv aerospace, X-ray raj, magnetrons thiab lwm yam kev siv. Cov qauv ib txwm muaj yog cov kabmob sib sib zog nqus lossis cov kabmob sib txuas, uas feem ntau ua los ntawm cov khoom siv hlau tsis xeb xws li GCr15 bearing steel lossis 9Cr18, thiab cov hlau tshiab xws li G60 siv rau hauv qee qhov chaw nqus tsev siab.
7. Cov kabmob uas siv lubricating rau nws tus kheej
Nws muaj lub tshuab ua kom lubrication ua ke thiab tsis xav tau lub tshuab ua kom lubrication sab nraud. Cov qauv ib txwm muaj xws li ib kab angular contact ball bearings thiab radial luv cylindrical roller bearings rau cov khoom siv uas lubrication txwv lossis nyuaj rau kev tswj hwm.
8. Cov kabmob ua los ntawm cov khoom siv ceramic
Haum rau cov xwm txheej ua haujlwm hnyav xws li kev kub ceev, kub siab, kub qis, xeb muaj zog, lub zog sib nqus muaj zog, lub tshuab nqus tsev thiab qhov chaw siab. Nws yog qhov zoo tagnrho rau cov ntawv thov siab vim nws muaj peev xwm dais tau siab, tiv taus kub zoo heev, ceev ceev kawg, tsis sib txhuam, lub neej ntev, tiv taus corrosion thiab rwb thaiv hluav taws xob zoo.
9. Cov kabmob ceev ceev
Haum rau Dm·n tus nqi tshaj 1.0 × 10 mm·r/min (Dm yog qhov nruab nrab txoj kab uas hla ntawm lub dov, n yog qhov ceev ntawm lub nplhaib sab hauv). Tam sim no, tus nqi tau tshaj 3.0 × 10, thiab txawm tias mus txog 3.5 × 10, uas yog siv dav hauv cov cuab yeej siv tshuab ceev ceev, aerospace thiab cov khoom siv precision.
