Muindasitiri yemazuva ano, kutarisa tembiricha nemazvo chikamu chakakosha chekudzora maitiro, kuvimbisa mhando, uye masisitimu ekuchengetedza. MaThermocouples—masensa etembiricha anoshandiswa zvakanyanya—anowanzo sangana nemamiriro ezvinhu akaoma akadai sekupisa kwakanyanya, makemikari anoparadza, masisitimu evacuum, uye minda yeplasma. Kuchengetedza masensa aya zvinobudirira kwakakosha kuti mashandiro agare zvakanaka. Machubhu eSapphire, akagadzirwa neakagadzirwa nearuminiyamu oxide imwe chete, aratidza kuva pakati pezvinhu zvakavimbika zvekudzivirira kwakadaro. Chinyorwa chino chinoongorora hunhu hwakasiyana hwemachubhu esapphire, mashandisirwo awo akasiyana-siyana, uye kunyanya, mashandiro awo anoshamisa semasheya ekudzivirira ethermocouple.

Zvinhu Zvakanakisisa zveMashandisirwo Anorema

Safira imhando ye aluminium oxide (Al₂O₃) ine kristalo uye iri pasi pedhaimani kana tichitarisa kuomarara, ichiwana 9 pachikero cheMohs. Kuomarara uku kunoshamisa kunoita kuti machubhu esapphire asanyanya kukwenywa, kukwenywa, uye kukanganiswa nemagetsi, kunyangwe kana achishandiswa kakawanda kana zvakanyanya.

Kupfuura simba remuchina, machubhu esapphire anokosheswa zvikuru nekuda kwekusagona kwawo makemikari. Anoramba akagadzikana uye asina simba kana paine akawanda maacid, zvinonyungudutsa, uye magasi anochinja-chinja, anosanganisira hydrogen fluoride, chlorine, uye sulfur compounds. Izvi zvinoabvumira kushanda zvinobudirira mumabasa ane makemikari akasimba kana plasma.

Pamusoro pezvo, mashandiro ekupisa esapphire anoshamisa. Inoramba ichipisa kwenguva refu kusvika pa2000°C uku ichiramba yakasimba. Kufamba kwayo mukupisa kunotsigira kutamiswa kwekupisa nekukurumidza, chinhu chakakosha zvikuru kana ichishandiswa muzvirongwa zvekuona tembiricha.

Chimwe chinhu chakakosha ndechekuti inopenya zvakanaka pa ultraviolet, visible, uye infrared wavelengths—kubva pa 0.3 μm kusvika 5 μm. Izvi zvinoita kuti machubhu esapphire akwanise kushandiswa pakuona kana kuti pakubatanidza thermal-optical monitoring systems.

Thermocouples uye Kudiwa Kwekudzivirirwa

Mathermocouple zvinhu zvakakosha mumhando dzakasiyana-siyana dzemasystem, kubva kumaovheni esimbi nemainjini eturbine kusvika kuma semiconductor reactors nemichina yekugadzira makemikari. Midziyo iyi inogadzira voltage zvichibva pamusiyano wetembiricha pakati pesimbi mbiri dzakasiyana dzakabatana kune rimwe divi. Kunyange zvazvo mathermocouple achikwanisa kushandiswa zvakasiyana-siyana uye akasimba, kusangana kwawo zvakananga nekupisa, zvinokuvadza, uye kuvhunduka kwemechanical zvinogona kupfupisa hupenyu hwazvo hwekushanda kana kuderedza kururama kwekuverengwa kwetembiricha.

Apa ndipo panoshanda machubhu esapphire semasheya ekudzivirira. Nekuvharira thermocouple mukati mechubhu yesapphire, sensor inobviswa munzvimbo yakaoma uku ichibvumira kutamiswa kwekupisa zvakanaka. Mugumisiro wacho inzwa inogara kwenguva refu uye yakavimbika iyo inochengetedza kururama kwakafanana kunyangwe mushure mekugara kwenguva refu mumamiriro ekushanda akasimba.

Kufambiswa kwekupisa kweSapphire kunoita kuti kupisa kusvike muthermocouple nekukurumidza uye zvakaenzana, zvichideredza kunonoka kwekupisa uye zvichivandudza nguva yekupindura. Uyezve, kuramba kwayo kurwiswa nemakemikari kunoita kuti sensor isakanganiswe nemarara, ngura, kana kuunganidzwa kwezvinhu—matambudziko anowanzo tambudza simbi kana ceramic protective sleeves.

Mashandisirwo Ezvinhu Mukutarisa Tembiricha

Mumaovheni anodziya zvakanyanya, machubhu esapphire anowanzo shandiswa kudzivirira ma thermocouples anotarisa mamiriro ezvinhu akaoma. Kugadzikana kwawo kwemakemikari kwakakosha mumhepo ine magasi e halogen akawanda, simbi dzakanyungudutswa, kana utsi hunoshanda. Semuenzaniso:

  • Kugadzira Semiconductor: Masheya eSapphire anodzivirira thermocouples panguva yekukura kwe epitaxial, kunyungudutsa wafer, uye maitiro ekushandisa doping, uko nzvimbo dzakachena uye kudzora tembiricha kwakanyatsokosha.

  • Makemikari Anogadzirisa Zvinhu: Munzvimbo dzinoita kuti zvinhu zviite sezviri nyore kana kuti dzine utsi hunoparadza, machubhu esapphire anochengetedza tembiricha kwenguva refu, zvichibvisa matambudziko ekusvibiswa.

  • Zvitofu zveVacuum: Machubhu eSapphire anodzivirira oxidation uye kukuvara kwemakemikari ku thermocouples pavanenge vachishanda pasi pe vacuum kana magasi asina simba ane pressure yakaderera.

  • Masisitimu Ekupisa: Injini dzejet, maturbine egasi, uye maburner emumaindasitiri anowanzo vimba nemathermocouples akachengetedzwa nesafire kuti aongorore kupisa kwakanyanya kuti pave nekushanda zvakanaka uye kuchengetedzeka.

Nekushandisa machubhu esapphire, mainjiniya vanokwanisa kuisa mathermocouples mumamiriro ezvinhu angadai asina kunaka zvakanyanya kune simbi yakajairwa kana magirazi. Izvi zvinowedzera huwandu hwekushanda kwemasystem ekutarisa kupisa uye zvinowedzera kushanda kwawo kwenguva refu.

Mamwe Mashandisirwo Emachubhu eSapphire muIndasitiri

Kunyange zvazvo dziviriro ye thermocouple iriyo inonyanya kushandiswa, machubhu esapphire anoshandiswa mune mamwe matekinoroji akawanda epamusoro:

  • Marambi eKuburitsa Mvura Yakanyanya (HID): Sezvinhu zvemaenvelopu, machubhu esapphire anodzivirira kupisa kwakanyanya uye mwaranzi yeUV/IR pasina kusviba kana kupfava.

  • Makamuri Ekuchera Plasma: Inoshandiswa senzvimbo dzekuona nekudzivirira ngarava nekuda kwekusakura kwayo.

  • Kunzwa kweInline Optical: Batidza spectroscopy, imaging, uye laser diagnostics kuburikidza nema process pipes pasina kusvibisa medium.

  • Kurapa Mvura uye Zvishandiso Zvekurapa: Nekuda kwekusasimba kwayo mumuviri uye kusakwanisa kushandisa makemikari, machubhu esapphire akakodzera masisitimu anoda kusasimba uye kusaita zvinhu zvakare.

  • Masisitimu Ekutumira NeLaser: Machubhu eSapphire anotungamira matanda ane simba guru asina kurasikirwa kwakanyanya kwemaziso uye kugadzikana kwakanyanya kwekupisa.

Mashandisirwo aya anobatsirwa nehunhu hukuru hwesafire—kusashanda zvakanaka kwemakemikari, kujeka kwemaziso, kuomarara kwakanyanya, uye kugadzikana kwekupisa—mumaindasitiri akasiyana-siyana akadai semuchadenga, hutano, petrochemicals, uye zvemagetsi.

Hunhu Hunokosha hweMachubhu eSapphire

  1. Rudzi rweKujeka: 0.3–5.0 μm (UV kusvika kuIR), yakakodzera kushandiswa nemaziso, nelaser, uye nespectroscopic

  2. Kuoma: Mohs 9—inodzivirira kukweshwa uye kukuvara pamusoro

  3. Kuramba Kupisa: Yakagadzikana kusvika 2030°C, ine conductivity yakakwira yekuchinjana kupisa nekukurumidza

  4. Kugara Kwemakemikari: Haisi kubatwa nezvinonyungudutsa zvakawanda, maasidhi, uye maalkali

  5. Kudzivirira Magetsi: Kurasikirwa kwe dielectric kwakasimba uye kurasikirwa kwe dielectric kwakaderera

  6. Kugadzikana kweDimensional: Inodzivirira kuwedzera kwekupisa uye kushanduka kwemamiriro ekunze kana yamanikidzwa

  7. Kuramba kwePlasma: Yakanakira kushandiswa munzvimbo dzine simba rakawanda senge PECVD kana ion implantation

Pfupiso uye Mabhenefiti eThermocouple Systems

  1. Machubhu eSapphire anounza musanganiswa wakasiyana wehunhu hunoaita kuti ave akakodzeradziviriro ye thermocouple:

    • Kururama Kwakawedzerwa: Kupisa kwakanyanya kunogonesa kupindura nekukurumidza

    • Kugara Kwakareba: Kuramba kupfeka uye ngura zvinodzivirira masensa kwenguva refu

    • Kushanda Kwakagadzikana: Inochengetedza hunhu hwemakanika kunyangwe mukupisa kwemhepo

    • Hazvisvibisi: Nzvimbo dzisina makemikari dzinoderedza zvikanganiso

    • Kugona Kwakawanda: Inobvumira kubatanidzwa kwekuona kwemaziso nekutarisa kwekupisa

Mhedziso

  1. Mathermocouples ndiwo musimboti wemasystem anodzivirira tembiricha, uye kuvimbika kwawo kunoenderana zvakanyanya nemhando yedzimba dzawo dzekudzivirira. Machubhu eSapphire, nekuda kwehunhu hwawo hunoshamisa hwezvinhu, anopa musanganiswa wakanakisa wekudzivirira kupisa, dziviriro yemakanika, uye kuchena kwemakemikari. Sezvo maindasitiri achiramba achida kunyatsojeka uye kugara kwenguva refu mumasystem ekupisa, mathermocouples anodzivirira machubhu eSapphire ari kuva mhinduro yakakosha yekuzadzisa zvinotarisirwa izvozvo.
