Sapphire Tubes Inosimudzira Thermocouple Kuvimbika

Tsanangudzo Pfupi

Muindasitiri yemazuva ano, kunyatso kutarisisa tembiricha chikamu chakakosha chekutonga kwemaitiro, kuvimbiswa kwemhando, uye masisitimu ekuchengetedza. Thermocouples - anoshandiswa zvakanyanya tembiricha sensors - anowanzo kuoneswa kune yakaoma nharaunda senge tembiricha yakakwira, makemikari anoparadza, vacuum masisitimu, uye minda yeplasma. Kuchengetedza masensa aya zvinobudirira kwakakosha pakugadzikana kwekushanda. Machubhu esafire, akagadzirwa kubva mukugadzira single-crystal aluminium oxide, aratidza kuve pakati pezvinhu zvinovimbika zvekudzivirira kwakadaro. Ichi chinyorwa chinoongorora hunhu hwakasiyana hwemachubhu esafire, kushandiswa kwavo kwakasiyana, uye kunyanya, kuita kwavo kwakasiyana-siyana se thermocouple kudzivirira sheaths.

Superior Material Yekuda Maapplication

Sapphire icrystalline fomu yealuminium oxide (Al₂O₃) uye inoiswa pazasi pedhaimani maererano nekuoma, inotora 9 pachiyero cheMohs. Uku kuoma kwakasarudzika kunoita kuti machubhu esafire arambe akasimba pakukwenya, abrasion, uye mashandiro emuchina, kunyangwe pasi pekushandiswa kazhinji kana zvakanyanya.

Kupfuura simba remagetsi, machubhu esafire anokosheswa zvakanyanya nekuda kwekusagadzikana kwemakemikari. Dzinoramba dzakatsiga uye dzinenge dziine maasidhi mazhinji, zvinonyungudutsa, uye magasi anoshanda, anosanganisira hydrogen fluoride, chlorine, uye sulfur compounds. Izvi zvinovabvumira kuti vashande nemazvo muzvirongwa zvinosanganisira makemikari ane hukasha kana plasma.

Pamusoro pezvo, kupisa kwesafire kuita kunoshamisa. Inoshingirira kuratidzwa kwenguva refu kune tembiricha yakakwira kusvika 2000 ° C ichichengeta kuvimbika kwayo kwechimiro. Thermal conductivity yayo inotsigira kukurumidza kupisa kupisa, chinhu chinonyanya kukosha kana chichishandiswa mumasisitimu ekunzwa tembiricha.

Imwe bhenefiti yakakosha ndeyekujeka kwayo kwe ultraviolet, inooneka, uye infrared wavelengths-kubva panosvika 0.3 μm kusvika 5 μm. Izvi zvinogadzira machubhu esafire akakodzera kuona kuona kana kusanganisa thermal-optical monitoring system.

Thermocouples uye Kudiwa Kwekudzivirirwa

Thermocouples zvinhu zvakakosha mumhando dzakasiyana-siyana dzemasisitimu, kubva muvira resimbi uye injini dzeturbine kusvika kune semiconductor reactor uye makemikari process michina. Midziyo iyi inoburitsa voltage zvichienderana nekusiyana kwetembiricha pakati pesimbi mbiri dzakasiyana dzakabatanidzwa kune rumwe rutivi. Nepo thermocouples dzichichinja-chinja uye dzakasimba, kuratidzwa kwayo kwakananga nekupisa, corrosive agents, uye mechanical shock zvinogona kupfupisa zvakanyanya hupenyu hwavo hwesevhisi kana kukanganisa kurongeka kwekuverenga tembiricha.

Apa ndipo panopinda machubhu esafire semashedhi ekudzivirira. Nekuvhara iyo thermocouple mukati mesapphire chubhu, sensor inoparadzaniswa kubva munzvimbo ine hutsinye ichiri kubvumira inobudirira kupisa kupisa. Mhedzisiro yacho ndeyekureba-inogara, yakavimbika sensor inochengetedza kurongeka kunoenderana kunyangwe mushure mekuratidzwa kwenguva refu kune hukasha hwekushanda mamiriro.

Sapphire's thermal conductivity inobvumira kupisa kusvika kune thermocouple nekukurumidza uye zvakafanana, kuderedza kupisa kwekushisa uye kugadzirisa nguva yekupindura. Uyezve, kupikisa kwayo kurwiswa kwemakemikari kunovimbisa kuti sensor haina kukanganiswa nemasara, corrosion, kana zvinhu zvakavakwa-nyaya dzinowanzotambudza simbi kana ceramic inodzivirira sleeves.

Shandisa Macases muTemperature Monitoring

Mumavira ekupisa anopisa, machubhu esafire anowanzo shandiswa kuchengetedza thermocouples inotarisisa mamiriro akaomarara. Kugadzikana kwavo kwemakemikari kwakakosha mumhepo yakapfuma mumagasi ehalogen, simbi dzakanyungudutswa, kana mhute inoshanda. Semuyenzaniso:

Semiconductor Manufacturing: Sapphire sheaths inodzivirira thermocouples panguva yekukura epitaxial, wafer annealing, uye doping process, uko kwakachena nharaunda uye chaiyo tembiricha kutonga kwakakosha.
Chemical Reactors: Mukuita kunokonzeresa kana corrosive mhute nharaunda, machubhu esafire anovimbisa kuchengetedzwa kwenguva refu kwe tembiricha probes, kubvisa kunetseka kusvibiswa.
Vacuum Furnaces: Sapphire chubhu inodzivirira oxidation uye kukuvara kwemagetsi kune thermocouples uchishanda pasi pevacuum kana yakaderera-kudzvinyirira inert magasi.
Combustion Systems: Jet engines, turbines gas, uye maindasitiri anopisa kazhinji anovimba nesafire-protected thermocouples kuti atarise zvakanyanya kupisa kwekuita uye kuchengetedza optimization.

Nekushandisa machubhu esafire, mainjiniya vanokwanisa kuendesa thermocouples mumamiriro ezvinhu angave akanyanya kukuvadza kune yakajairwa simbi kana magirazi sheaths. Izvi zvinowedzera huwandu hwekushanda kwemasisitimu ekutarisa kupisa uye kuwedzera kushanda kwavo kwenguva refu.

Yekuwedzera Indasitiri Zvishandiso zveSapphire Tubes

Nepo kudzivirira kwe thermocouple iri inotungamira application, machubhu esafiri anoshandiswa mune mamwe akawanda epamusoro matekinoroji:

Mwenje weHigh-Intensity Discharge (HID).: Sezvinhu zvehamvuropu, machubhu esafiri anomira nekupisa kwakanyanya uye UV / IR mwaranzi pasina kupfuta kana kupfava.
Plasma Etching Chambers+
Inline Optical Sensing: Gonesa spectroscopy, imaging, uye laser diagnostics kuburikidza nemaitiro mapaipi pasina kusvibisa yepakati.
Kurapa Mvura uye Zvishandiso Zvekurapa: Nekuda kweiyo bio-inertness uye makemikari kuramba, machubhu esafiri akanakira masisitimu anoda sterility uye kusaita-reactivity.
Laser Delivery Systems: Machubhu eSapphire anotungamira matanda esimba-akakwirira ane kushomeka kwemaziso kurasikirwa uye yakanyanya kugadzikana yekupisa.

Aya maapplication anobatsirwa kubva kune akakosha esafiro - makemikari inertness, kujeka kwemaziso, kuomarara kwakanyanya, uye kugadzikana kwemafuta - mumaindasitiri akasiyana seaerospace, hutano hwehutano, petrochemicals, uye zvemagetsi.

Core Physical Properties yeSapphire Tubes

Dimensional Kugadzikana: Kurwisana nekuwedzera kwekupisa uye deformation pasi pekumanikidzwa
Plasma Resistance: Yakanakira kushandiswa munzvimbo dzakakwirira-simba sePECVD kana ion implantation

Pfupiso uye Mabhenefiti eThermocouple Systems

Sapphire machubhu anounza musanganiswa wakasiyana wehunhu hunovaita vakakodzerathermocouple kudzivirira:
- Kunyatsorurama: High thermal conductivity inogonesa kukurumidza kupindura
- Kuwedzerwa Kusimba: Kuramba kupfeka uye kuora kunodzivirira sensors kwenguva refu
- Yakagadzikana Performance: Inochengetedza kutendeseka kwemichina kunyangwe mukuchovha mitoro inopisa
- Kwete-kusvibisa: Kemikari inert nzvimbo inoderedza kukanganisa kunobva
- Multifunctional Kugona: Inogonesa kubatanidzwa kweoptical sensing nekutarisa kupisa

Mhedziso

Thermocouples iri pamwoyo wetembiricha-sensitive system, uye kuvimbika kwavo kunoenderana zvakanyanya nemhando yeimba yavo yekudzivirira. Machubhu eSapphire, nekuda kweawo anoshamisa zvinhu zvivakwa, anopa yakanakisa iripo musanganiswa wekupisa kupisa, kudzivirira kwemuchina, uye kuchena kwemakemikari. Sezvo maindasitiri achiramba achida kunyatsojeka uye kusimba mumasisitimu ekupisa, sapphire chubhu-yakachengetedzwa thermocouples iri kuita mhinduro yakakosha yekuzadzisa izvo zvinotarisirwa.
