Tungsten Carbide Bearings: Umuti Uhebuje wo Gukoresha Inganda Zikomeye

Mu rwego rwimashini zinganda, ibyuma bikora nkumugongo wimikorere yoroshye, ariko ntabwo ibyaremwe byose byaremewe kimwe. Tungsten karbide yatwaye yagaragaye nkumukino uhindura umukino, utanga uburebure butagereranywa nibikorwa birenze ibikoresho gakondo nkibyuma cyangwa ceramic. Igizwe na karubide ya tungsten - igizwe na tungsten na karubone izwiho gukomera gukabije (icya kabiri nyuma ya diyama) no kurwanya kwambara - ibyo bikoresho byakozwe kugirango bitere imbere ahantu hasabwa cyane, bigatuma biba ingenzi mu nganda zikomeye.

1. Inganda zicukura amabuye y'agaciro: Gutsinda Abrasion n'imizigo iremereye

Ibikorwa byo gucukura amabuye y'agaciro bihura ningorabahizi: ibice byamabuye yangiza hamwe ningaruka zikomeye zangiza vuba ibyuma bisanzwe. Kurugero, urusyo rusya rutunganya urutare rukomeye (urugero, granite, ubutare bwumuringa) rufite ibiro 500+ byingaruka zingaruka kuri buri cyiciro, mugihe sisitemu ya convoyeur itwara amabuye y'icyuma igaragaza ibyuma byangiza ivumbi. Ibyuma bitwara ibyuma muribi bihe birananirana mugihe cyamasaha 200-300 yo gukora, bigahatira amasaha 4-6 yigihe gito cyo guhembwa kubasimbuye.

Tungsten karbide itwara iyi ngingo yububabare hamwe na 90-95 ya HRA hamwe no guhangana ningaruka nyinshi. Ikirombe cy'umuringa muri Chili cyasimbuye ibyuma bya tungsten karbide ihinduranya umusaya wibanze, kandi ibisubizo byarahindutse:

Imyaka yo kubaho yasimbutse kuva ku masaha 250 igera ku masaha 2.800 (11x ndende), igabanya inshuro zisimburwa kuva buri kwezi kugeza buri mwaka.

Igihe cya Crusher cyiyongereyeho 35%, bizamura ubushobozi bwo gutunganya amabuye ya buri munsi kuva kuri toni 1200 kugera kuri toni 1,620.

Amafaranga yo gufata neza yagabanutseho 68%, kubera ko guhagarika bike byakuyeho ibikoresho nibikoresho bidafite akazi.

Mu birombe by’amakara yo mu kuzimu, aho ubushuhe n’umukungugu w’amakara byihuta kwangirika, imiterere ya karubide ya tungsten nayo irinda ingese-bitandukanye n’ibyuma, bisaba kugenzura amavuta buri cyumweru, gutwara karbide bikenera ubugenzuzi buri kwezi, bikagabanya imirimo yo kubungabunga aho ikorera.

2. Inganda za peteroli na gazi: Kurwanya umuvuduko ukabije na ruswa

Gucukura umwobo hamwe no gutunganya amavuta arota inzozi zibiri zo kwifata: umuvuduko ukabije (kugeza 15,000 psi) + ubushyuhe bwinshi (300 ° C +) + Amazi yo gutobora. Ibyuma bifata ibyuma hano bigabanuka mumasaha 50-80, kubera ko icyondo cya acide kirya hejuru yicyuma hamwe nibikoresho byumuvuduko - buri kunanirwa bisaba gukurura umugozi wose wimyitozo, bitwara 50.000-100.000 mugihe cyo kumanuka kuri buri kintu.

Tungsten karbide itwara ibintu byihariye bihindura izo mbogamizi mubibazo bitari:

Imbaraga zabo zo guhonyora (6000 MPa) zirwanya ihindagurika munsi yumuvuduko wo hasi, mugihe ubushyuhe bwumuriro bugera kuri 500 ° C butuma nta mpinduka zingana mubushyuhe bwinshi.

Umucuruzi ukomeye mu bucukuzi bwa peteroli mu kigobe cya Mexico yakoresheje tungsten karbide ya moteri ya moteri yo gucukura itambitse, ikomeza ubuzima kuva ku masaha 70 kugeza ku masaha 650. Uyu mugozi wimyitozo wagabanutse uva inshuro 8 kuririba kugeza inshuro 1, ugabanya igihe cyo kurangiza neza iminsi 22 no kugabanya amafaranga $ 350,000 kuririba.

Mu ruganda rutunganya amavuta, aho pompe zitwara peteroli ikungahaye kuri sulfure, karubide ya tungsten irwanya ruswa nayo irabagirana. Uruganda rutunganya uruganda rwa Texas rwatangaje ko nyuma yo guhindukira kuri karbide muri pompe zayo zihererekanyabubasha, kunanirwa kashe (biterwa n’icyuma) byagabanutse kuva kuri 12 ku mwaka bigera kuri 2, kandi imikorere ya pompe yazamutseho 9% kubera kugabanya ubukana.

3. Inganda zo mu nyanja n’imiti: Gutsinda ruswa nubushuhe

Umuyoboro wo mu nyanjaer shafts hamwe na pompe zitunganya imiti birwanya amazi yumunyu cyangwa guhura kwinshi - ibyuma byibyuma hano byangirika mumezi 3-6, biganisha ku guhuza ibiti no kumeneka. Ku bwato bwo hanze, gusimbuza icyuma gisaba ibyuma-byumye, bigura 20.000-50.000 kumunsi.

Imiti ya Tungsten carbide idafite imbaraga (irwanya 99% byumusemburo winganda namazi yumunyu) bikuraho ibi byago:

Amato yo muri Noruveje yarobye ibikoresho byayo hamwe na tungsten karbide yamashanyarazi, yongerera ubuzima kuva ku mezi 6 kugeza ku myaka 5. Inshuro yumye yagabanutse kuva buri mwaka kugeza rimwe mumyaka 5, bizigama $ 120.000 kuri buri cyombo mugiciro cyo kubungabunga.

Mu ruganda rukora imiti rutanga aside irike, karubide ya tungsten ya shitingi ya shitingi yasimbuye ibyuma - mbere, ibyuma byananiranye buri mezi 2 bitewe na ruswa, ariko ibyuma bya karbide byakoraga mu gihe cy’amezi 18, bikagabanya ihagarikwa ridateganijwe kuri 90%.

4. Ingufu zisubirwamo (Imbaraga zumuyaga): Kwihangana kunyeganyega hamwe nibintu byo hanze

Imashini itanga umuyaga uhura n’umuvuduko uhoraho uterwa n'umuyaga (kugeza kuri Hz 50) + ihindagurika ry'ubushyuhe (-40 ° C kugeza 60 ° C). Ibyuma bifata ibyuma muri turbine nyamukuru birananirana mumyaka 3-4, kandi kubisimbuza bisaba gukodesha kane (15,000-30.000 kumunsi) niminsi 3-5 yo kumanura.

Tungsten karbide ya coefficient nkeya yo guterana (0.05, kimwe cya kabiri cyibyuma) hamwe nuburyo bwo kunyeganyega bikemura ibi:

Uruganda rw’umuyaga rwo mu Budage rwashyizeho karubide ya tungsten muri 20 muri turbine zayo 2,5. Mugihe cyimyaka 5, ntanumwe mubitwara karbide byananiranye, mugihe ibyuma bya turbine byegeranye byasabye gusimburwa kabiri. Umurima wazigamye $ 450,000 yo kubungabunga no kongera ingufu zingana na 4% (kubera guhagarika bike).

5. Ibyiringiro byisoko rya Tungsten Carbide Yifata: Abashoferi bakura niterambere ryigihe kizaza

Isoko rya tungsten karbide ku isi ryiteguye kuzamuka cyane mu myaka icumi iri imbere, bitewe no kuzamura inganda, gukenera ibice byizewe cyane, no kwagura inzego zikoresha amaherezo. Nk’uko ikigo cy’ubushakashatsi cy’inganda cyitwa Grand View Research kibitangaza ngo biteganijwe ko isoko ry’inganda ku isi (harimo na tungsten carbide variants) rizagera kuri miliyari 128.7 z'amadolari mu 2030, hamwe na karubide ya tungsten ifite imigabane yiyongera - biteganijwe ko iziyongera kuri CAGR ya 7.2% kuva 2024 kugeza 2030, ikarenza isoko rusange (CAGR ya 5.1%).
