Tungsten Carbide Bearings: Ƙarshen Magani don Babban Ayyukan Masana'antu

A cikin yanayin injunan masana'antu, bearings suna aiki a matsayin kashin baya na aiki mai santsi, amma ba duk bearings an halicce su daidai ba. Tungsten carbide bearings sun fito a matsayin mai canza wasa, suna ba da dorewa da aiki mara misaltuwa wanda ya zarce kayan gargajiya kamar karfe ko yumbu. Ya ƙunshi tungsten carbide-wanda ya ƙunshi tungsten da carbon sananne saboda tsananin taurinsa (na biyu kawai ga lu'u-lu'u) da juriya na sawa - waɗannan bearings an ƙirƙira su don bunƙasa a cikin mafi yawan mahalli masu buƙata, wanda ke sa su zama makawa a cikin manyan masana'antu.

1. Masana'antar hakar ma'adinai: Cin nasara abrasion da nauyi mai nauyi

Ayyukan hakar ma'adinai suna fuskantar babban ƙalubale: barbashi na ma'adinai da matsananciyar tasiri waɗanda ke lalata abubuwan ƙarfe na yau da kullun. Misali, masu muƙamuƙi masu sarrafa dutse mai ƙarfi (misali, granite, jan ƙarfe) abubuwan da ke ɗaukar nauyi zuwa 500+ kilogiram na ƙarfin tasiri a kowane zagayowar, yayin da tsarin isar da iskar tama yana fallasa bearings zuwa ƙura mai dorewa. Ƙarfe a cikin waɗannan al'amuran yawanci suna kasawa a cikin sa'o'i 200-300 na aiki, yana tilasta 4-6 hours na raguwa mai tsada a kowane canji.

Tungsten carbide bearings suna magance wannan batu mai zafi tare da taurin 90-95 HRA da babban tasiri mai tasiri. Wani mahakar jan karfe a Chile ya maye gurbin karfen karfe tare da bambance-bambancen tungsten carbide a cikin muƙamuƙi na farko, kuma sakamakon ya canza:

Tsawon rayuwa ya yi tsalle daga awanni 250 zuwa awanni 2,800 (tsawon 11x), yanke mitar sauyawa daga kowane wata zuwa shekara.

Lokacin aikin Crusher ya ƙaru da 35%, yana haɓaka ƙarfin sarrafa tama na yau da kullun daga tan 1,200 zuwa tan 1,620.

Kudin kulawa ya ragu da kashi 68%, saboda ƙarancin rufewa ya kawar da tsadar kayan aiki da kayan aiki.

A cikin ma'adinan kwal na karkashin kasa, inda danshi da ƙurar kwal ke haɓaka lalata, yanayin inert na tungsten carbide kuma yana hana tsatsa-ba kamar nau'in ƙarfe ba, wanda ke buƙatar duban sabulu na mako-mako, bearings carbide yana buƙatar dubawa na wata-wata kawai, yana rage yawan aikin kula da wurin.

2. Masana'antar mai da iskar gas: Jurewa matsanancin matsin lamba da lalata

Hakowa Downhole da tace mai suna ba da mafarkai guda biyu don ɗaukar nauyi: matsananciyar matsa lamba (har zuwa 15,000 psi) + yanayin zafi mai zafi (300°C+) + ruwa mai lalata. Ƙarfe a nan yana raguwa a cikin sa'o'i 50-80, yayin da laka mai acidic ke cinyewa a saman ƙarfe da kuma abubuwan da ke haifar da matsa lamba-kowace gazawar tana buƙatar cire duk igiyoyin rawar soja, farashi 50,000-100,000 a cikin raguwa a kowane lokaci.

Abubuwan musamman na Tungsten carbide bearings suna juya waɗannan ƙalubalen zuwa abubuwan da ba su da tushe:

Ƙarfinsu na matsawa (6,000 MPa) yana tsayayya da nakasawa a ƙarƙashin matsa lamba na ƙasa, yayin da kwanciyar hankali na zafi har zuwa 500 ° C yana tabbatar da cewa babu canje-canje mai girma a yanayin zafi.

Wani babban ma'aikacin mai a Tekun Mexico ya yi amfani da tungsten carbide bearings a cikin injinan hakowa a kwance, yana tsawaita rayuwa daga sa'o'i 70 zuwa sa'o'i 650. Wannan raguwar igiyar haƙora tana jan daga sau 8 a kowace rijiyar zuwa sau 1, yana yanke lokacin kammala rijiyar da kwanaki 22 tare da yanke farashin dala 350,000 kowace rijiya.

A cikin matatun mai, inda famfunan ruwa ke jigilar ɗanyen mai mai arzikin sulfur, juriyar lalatawar tungsten carbide kuma tana haskakawa. Wata matatar mai a Texas ta ba da rahoton cewa bayan sauya sheka zuwa carbide bearings a cikin famfunan danyen man fetur, gazawar hatimi (sakamakon tsatsa na karfe) ya ragu daga 12 a kowace shekara zuwa 2, kuma ingancin famfo ya inganta da kashi 9% saboda raguwar rikice-rikice.

3. Masana'antar Ruwa da Sinadarai: Kashe lalata da danshi

Jirgin ruwaer shafts da sinadarai masu sarrafa famfo suna fama da ruwan gishiri akai-akai ko fallasa-karfe a nan yana yin tsatsa a cikin watanni 3-6, wanda ke haifar da rashin daidaituwa da ɗigogi. Don jiragen ruwa na teku, maye gurbin na'ura mai ɗaukar hoto yana buƙatar busasshen docking, farashin 20,000-50,000 kowace rana.

Rashin ƙarancin sinadarai na Tungsten carbide (yana tsayayya da 99% na kaushi na masana'antu da ruwan gishiri) yana kawar da wannan haɗarin:

Wani jirgin ruwan kamun kifi na kasar Norway ya yi wa jiragen ruwan sa kayan kwalliyar tungsten carbide propeller bearings, yana tsawaita rayuwa daga watanni 6 zuwa shekaru 5. Mitar docking ɗin bushewa ya ragu daga shekara zuwa sau ɗaya a kowace shekara 5, yana adana $120,000 akan kowane jirgin ruwa a farashin kulawa.

A cikin wani sinadari da ke samar da sulfuric acid, tungsten carbide bearings a cikin agitator shafts ya maye gurbin bambance-bambancen karfe - a baya, bearings na karfe ya kasa kowane watanni 2 saboda lalatawar acid, amma bearings carbide yana ci gaba da aiki har tsawon watanni 18, yana rage rufewar da ba a shirya ba da kashi 90%.

4. Makamashi Mai Sabunta (Ikon Iska): Jurewa Vibration da Abubuwan Waje

Masu samar da injin injin iska suna fuskantar girgizar da ke haifar da iska akai-akai (har zuwa 50 Hz) + yanayin zafi (-40°C zuwa 60°C). Karfe bearings a cikin manyan ramummuka yawanci kasawa cikin shekaru 3-4, kuma maye gurbinsu yana buƙatar hayar crane (15,000-30,000 kowace rana) da kwanaki 3-5 na raguwa.

Tungsten carbide's low coefficient na gogayya (0.05, rabin na karfe) da vibration damp Properties warware wannan:

Wata gonar iska ta Jamus ta sanya belin tungsten carbide a cikin 20 daga cikin injina na 2.5MW. Fiye da shekaru 5, babu ɗayan carbide bearings da ya gaza, yayin da ƙarfin ƙarfe a cikin injin turbin da ke kusa da shi yana buƙatar sauyawa sau biyu. Gonar ta adana dala 450,000 a cikin farashin kulawa da ƙara yawan makamashi da kashi 4% (saboda ƙarancin rufewa).

5. Hasashen Kasuwa na Tungsten Carbide Bearings: Direbobin Ci gaba da Yanayin Gaba

Kasuwancin tungsten carbide bearings na duniya yana shirye don haɓaka mai ƙarfi a cikin shekaru goma masu zuwa, haɓaka haɓaka masana'antu, buƙatun abubuwan dogaro mai ƙarfi, da haɓaka sassan amfani da ƙarshen. A cewar kamfanin bincike na masana'antu Grand View Research, ana sa ran kasuwar masana'antu ta duniya (ciki har da bambance-bambancen tungsten carbide) za su kai dala biliyan 128.7 nan da shekarar 2030, tare da tungsten carbide bearings suna yin kaso mai girma - wanda aka yi niyyar girma a CAGR na 7.2% daga 2024 zuwa 2030, wanda ya zarce na kasuwar gaba ɗaya.5.
