Tungsten Carbide Bearings: Tharollo ea ho qetela bakeng sa Likopo tse Phahameng tsa Ts'ebetso ea Indasteri

Sebakeng sa mechine ea indasteri, li-bearings li sebetsa e le mokokotlo oa ts'ebetso e boreleli, empa ha se li-bearings tsohle tse bōpiloeng tse lekanang. Li-bearings tsa Tungsten carbide li hlahile e le papali ea papali, e fanang ka nako e telele le ts'ebetso e ke keng ea lekanngoa e fetang lisebelisoa tsa setso tse kang tšepe kapa ceramic. E entsoe ka tungsten carbide-e leng motsoako oa tungsten le carbon e tsebahalang ka ho thatafala ha eona (ea bobeli ho daemane) le ho hana ho roala-li-bearings tsena li etselitsoe hore li atlehe libakeng tse boima ka ho fetisisa, e leng se etsang hore e be tsa bohlokoa ho feta liindasteri tsa bohlokoa.

1. Indasteri ea Merafo: Ho Hlōla ho Abrasion le Meroalo e Boima

Ts'ebetso ea merafo e tobana le phephetso ea mantlha: likaroloana tsa ore tse hlabang le meroalo e matla e senyang kapele li-bearings tse tloaelehileng tsa tšepe. Mohlala, li-crushers tsa mohlahare li sebetsanang le majoe a thata (mohlala, granite, copper ore) ho isa ho 500+ kg ea matla a ts'ebetso ka potoloho, ha litsamaiso tsa li-conveyor tse tsamaisang tšepe li pepesa li-bearings hore li senye lerōle kamehla. Li-bearings tsa tšepe maemong ana hangata li hloleha nakong ea lihora tse 200-300 tsa ts'ebetso, 'me li qobella lihora tse 4-6 tsa ho theola nako e theko e boima ka nako e ngoe le e ngoe.

Li-bearings tsa Tungsten carbide li sebetsana le ntlha ena ea bohloko ka boima ba tsona ba 90-95 HRA le ho hanyetsa tšusumetso e phahameng. Morafo oa koporo oa Chile o ile oa nkela li-bearings tsa tšepe sebaka ka mefuta e fapaneng ea tungsten carbide ho li-crusher tsa eona tsa mantlha tsa mohlahare, 'me liphetho li ile tsa fetoha:

Nako ea bophelo e nyolohile ho tloha ho lihora tse 250 ho isa ho lihora tse 2,800 (11x nako e telele), ho fokotsa makhetlo a mangata ho tloha khoeli le khoeli ho isa ho selemo.

Nako ea ho senya nako e eketsehile ka 35%, e matlafatsa matla a ts'ebetso ea ore letsatsi le letsatsi ho tloha ho lithane tse 1,200 ho isa ho lithane tse 1,620.

Litšenyehelo tsa tlhokomelo li theohile ka 68%, kaha ho koaloa ho fokolang ho felisitse litšenyehelo tsa basebetsi le lisebelisoa tse sa sebetseng.

Meepong ea mashala a ka tlas'a lefatše, moo mongobo le lerōle la mashala li potlakisang ho bola, tlhaho ea tungsten carbide ea inert e boetse e thibela mafome-ho fapana le li-bearings tsa tšepe, tse hlokang ho hlahlojoa ha lubrication beke le beke, li-carbide bearings li hloka feela tlhahlobo ea khoeli le khoeli, ho fokotsa mosebetsi oa ho lokisa setšeng.

2. Indasteri ea Oli le Khase: Ho Mamela Khatello e Feteletseng le Khoho

Ho phunya likoti le ho hloekisa oli ho hlahisa litoro tse peli tse tšosang bakeng sa li-bearings: khatello e feteletseng (ho fihla ho 15,000 psi) + mocheso o phahameng (300 ° C+) + maro a cheka a senyang. Li-bearings tsa tšepe mona li senyeha ka lihora tse 50-80, kaha seretse se nang le asiti se ja holim'a tšepe le likarolo tsa khatello ea khatello - ho hlōleha ho hong le ho hong ho hloka ho hula khoele eohle ea ho cheka, e bitsang 50,000−100,000 ka nako ea ho theoha ketsahalong ka 'ngoe.

Thepa e ikhethang ea li-tungsten carbide e fetola mathata ana hore e se ke ea e-ba litaba:

Matla a bona a hatellang (6,000 MPa) a hanana le deformation tlas'a khatello e tlaase, ha botsitso ba mocheso ho fihlela ho 500 ° C bo tiisa hore ha ho na liphetoho tse lekaneng mocheso o phahameng.

Setsebi se seholo sa sebaka sa oli Koung ea Mexico se sebelisitse li-bearings tsa tungsten carbide lienjeneng tsa eona tsa ho cheka tse tšekaletseng, e leng se eketsang bophelo ho tloha ho lihora tse 70 ho isa ho tse 650. Mohala ona o fokolitsoeng oa ho cheka o hula ho tloha makhetlo a 8 selibeng ho ea ho 1 nako, e fokotsa nako ea ho qeta hantle ka matsatsi a 22 le ho fokotsa litšenyehelo ka $350,000 seliba se le seng.

Libakeng tsa ho hloekisoa ha oli, moo lipompo li tsamaisang oli e tala e nang le sebabole, ho hanyetsa kutu ea tungsten carbide le hona hoa khanya. Setsi sa tlhoekiso sa Texas se tlalehile hore ka mor'a ho fetohela li-carbide bearings lipompong tsa eona tsa phetisetso e tala, ho hloleha ha tiiso (ho bakiloeng ke mafome a tšepe) ho theohile ho tloha ho 12 ka selemo ho ea ho 2, mme katleho ea pompo e ntlafalitsoe ka 9% ka lebaka la khohlano e fokotsehileng.

3. Liindasteri tsa Marine le Lik'hemik'hale: Ho Hlōla Corrosion le Mongobo

Sekepe sa metsinglipompo tsa tšepe le lipompo tsa ho lokisa lik'hemik'hale li loantšana le metsi a letsoai a sa khaotseng kapa ho pepeseha ha solvent-libere tsa tšepe mona li rusa nakong ea likhoeli tse 3-6, e leng se lebisang ho se lumellaneng ha shaft le ho lutla. Bakeng sa likepe tse lebōpong la leoatle, ho nkela sebaka sa propeller sebaka ho hloka ho omisa, ho bitsa 20,000-50,000 ka letsatsi.

Ho se sebetse ha lik'hemik'hale tsa Tungsten carbide (e hanela 99% ea lihlapolli tsa indasteri le metsi a letsoai) ho felisa kotsi ena:

Sekepe sa likepe tsa ho tšoasa litlhapi sa Norway se ile sa hlomella likepe tsa sona ka li-tungsten carbide propeller bearings, tse eketsang bophelo ho tloha likhoeling tse 6 ho isa ho tse 5. Maqhubu a Dry-docking a theohile ho tloha selemo le selemo ho isa hanngoe ka mor'a lilemo tse 5, a boloka $120,000 ka sekepe ka litšenyehelo tsa tlhokomelo.

Setsing sa lik'hemik'hale se hlahisang sulfuric acid, li-bearings tsa tungsten carbide ka har'a li-agitator shafts li ile tsa nkela mefuta e sa tšoaneng ea tšepe sebaka-pele, li-bearings tsa tšepe li ne li hlōleha ka mor'a likhoeli tse ling le tse ling tse peli ka lebaka la ho bola ha asiti, empa li-carbide bearings li ne li sebetsa ka nako ea likhoeli tse 18, li fokotsa ho koala ho sa reroang ka 90%.

4. Matla a Tsosolositsoeng (Matla a Moea): Ho mamella Vibration le Lintho tsa Kantle

Lijenereithara tsa turbine tsa moea li tobana le ho thothomela ho sa khaotseng ho bakoang ke moea (ho fihla ho 50 Hz) + ho fetoha ha mocheso (-40°C ho ea ho 60°C). Li-bearings tsa tšepe tse ka har'a li-shafts tse kholo tsa turbine hangata lia hloleha ka lilemo tse 3-4, 'me ho li khutlisa ho hloka khiriso ea crane (15,000−30,000 ka letsatsi) le matsatsi a 3-5 a ho phomola.

Khokahano e tlase ea Tungsten carbide (0.05, halofo ea tšepe) le thepa ea ho thothomela e rarolla sena:

Polasi ea moea ea Jeremane e kentse libering tsa tungsten carbide ho tse 20 tsa li-turbine tsa eona tsa 2.5 MW. Ho feta lilemo tse 5, ha ho le e 'ngoe ea li-bearings tsa carbide e ileng ea hlōleha, ha li-bearings tsa tšepe tse ka har'a li-turbine tse haufi li ne li hloka ho nkeloa sebaka habeli. Polasi e bolokile $450,000 ka litšenyehelo tsa tlhokomelo le ho eketsa tlhahiso ea matla ka 4% (ka lebaka la ho koala ho fokolang).

5. Litebello tsa Mmaraka tsa Tungsten Carbide Bearings: Bakhanni ba Kholo le Mekhoa ea Kamoso

Mmaraka oa lefats'e oa li-tungsten carbide bearings o mothating oa kholo e matla lilemong tse leshome tse tlang, o susumetsoa ke ntlafatso ea indasteri, tlhokahalo ea likarolo tse ts'eptjoang haholo, le katoloso ea likarolo tse sebelisang pheletso. Ho latela feme ea lipatlisiso tsa indasteri ea Grand View Research, 'maraka oa lefats'e oa liindasteri (ho kenyeletsoa mefuta e fapaneng ea tungsten carbide) e lebelletsoe ho fihla ho $ 128.7 bilione ka 2030,' me li-tungsten carbide bearings li ikarabella bakeng sa karolo e ntseng e eketseha - e lebelletsoeng ho hola ho CAGR ea 7.2% ho tloha 2024 ho isa 2030, e feta 5CA ka kakaretso.
