Mathermocouples ndiwo musimboti wekutarisa tembiricha mumaindasitiri akawanda—kubva pakunyungudutsa simbi kusvika pakugadzirwa kwemakemikari. Asi, mashandiro avo uye hupenyu hwavo zvinoenderana zvachose nechinhu chimwe chakakosha: chubhu yekudzivirira. Munzvimbo dzakaoma dzemaindasitiri, machubhu ekudzivirira echinyakare ethermocouple (akagadzirwa nesimbi, alumina, kana pure silicon carbide) anowanzo kundikana kutsungirira kupisa kwakanyanya, ngura, kana zvidimbu zvinokuvadza. Izvi zvinotungamira mukutsiviwa kwethermocouple kakawanda, data retembiricha risiri iro, uye nguva inodhura yekugadzira.
Kana waneta nekutadza kutevedzera kuvimbika kwe thermocouple,Machubhu ekudzivirira eSilicon Nitride akabatanidzwa neSilicon Carbide (NSiC) Thermocouplendiyo mhinduro inochinja-chinja yaunoda. Yakagadzirwa kuchengetedza thermocouples mumamiriro ezvinhu akaoma zvikuru, machubhu eNSiC anovimbisa kunzwa tembiricha kwakaringana uye kwakarurama ukuwo achivandudza hupenyu hwebasa remidziyo yako yekuyera yakakosha.
Nei Silicon Nitride Yakasungwa neSilicon Carbide Isingawanzoonekwi senzira yekudzivirira thermocouple
Machubhu ekudzivirira eThermocouple anoda kuenzana kwakasiyana kwehunhu: kudzivirira kupisa, kudzivirira ngura, simba remakanika, uye kufambisa kupisa. NSiC inobudirira munzvimbo idzi dzese, ichipfuura zvinhu zvechinyakare mune zvese zvakakosha:
1. Kuramba Kupisa Kwakanyanya Kwekunzwa Kusingavhiringidzwi
Machubhu ekudzivirira eNSiC thermocouple anoshanda mukupisa kunodarika 1,500°C. Machubhu ekudzivirira eNSiC thermocouple anobata izvi zviri nyore—aine tembiricha inoshanda kusvika 1,600°C (2,912°F) uye anoramba kwenguva pfupi kusvika 1,700°C (3,092°F). Kusiyana nemachubhu esimbi anonyungudutsa kana kuomesa, kana machubhu ealumina anotsemuka kana kupisa kuchipisa, NSiC inochengetedza chimiro chayo kunyangwe panguva yekuchinja-chinja kwekupisa nekukurumidza. Izvi zvinoreva kuti thermocouple yako inoramba yakachengetedzwa, uye data rako retembiricha rinoramba rakarurama—zvisinei nekuti kupisa kwakanyanya sei.
2. Kuramba Kukuru Kwengura Kudzivirira Midhiya Inotsamwisa
Maitiro emaindasitiri anowanzo pinza mathermocouples musimbi dzakanyungudutswa (aluminium, zinc, copper), acidic/alkaline solutions, kana magasi anoparadza (sulfur dioxide, chlorine). Maumbirwo eNSiC akakora, ane nitride-bonded anoita kuti zvinhu izvi zvisapindike. Kusiyana nemachubhu esilicon carbide akachena, anowanzo sanganiswa neoxidation munzvimbo dzine tembiricha yakanyorova, maumbirwo akasiyana eNSiC anowedzera kuramba oxidation—zvichivimbisa kuti thermocouple yako inoramba yakadzivirirwa kubva mukuora kwemakore. Izvi zvakakosha pakushandiswa kwakadai sekugadzirisa makemikari, kupisa marara, uye kugadzira zvinhu zvebhatiri.
3. Simba Rinoshamisa reMichina Rinodzivirira Kupfekwa & Kukanganiswa
Machubhu ekudzivirira eNSiC thermocouple ari mumafekitori esimende, magwenya emagetsi, kana munzvimbo dzinogadziriswa zvicherwa anotarisana nematambudziko anogara achiitika: guruva rinoputika, zvidimbu zvinobhururuka, uye kukanganiswa nemagetsi. Machubhu ekudzivirira eNSiC thermocouple akavakwa kuti adzivise matambudziko aya, ane simba rekuchinjika rinodarika 300 MPa uye kuomarara kweVickers (HV10) kwe ≥ 1,800. Izvi zvinoita kuti agare kwenguva refu ka3-5 kupfuura machubhu echinyakare, zvichideredza kudiwa kwekutsiviwa kakawanda. Pakushanda kwako, izvi zvinoreva kuti nguva shoma yekushanda, mari shoma yekugadzirisa, uye kushanda kwethermocouple kwakavimbika.
4. Kufambisa Kwekupisa Kwakakodzera Kuti Kuverengerwe Kwakakasika Uye Kwakarurama
Kukosha kwethermocouple kuri mukukwanisa kwayo kupindura nekukurumidza kukuchinja kwetembiricha. Kufambiswa kwekupisa kweNSiC (60–80 W/(m·K)) kwakakwira zvakanyanya kupfuura kwealumina kana machubhu esimbi, zvichiita kuti kupisa kupfuure nekukurumidza kubva mukuita kuenda ku thermocouple junction. Izvi zvinoita kuti thermocouple yako ipe data rakarurama uye rinoshanda panguva chaiyo—zvakakosha pakuchengetedza kudzora maitiro uye kunaka kwechigadzirwa. Pamusoro pezvo, low thermal expansion coefficient yeNSiC (3.5–4.5 × 10⁻⁶/°C) inoderedza kushushikana kwekupisa, ichidzivirira kuputika kunogona kukanganisa kurongeka kwekuyera.
5. Kugara kwenguva refu kunobatsira pakuderedza mitengo yekuva muridzi weimba
Kunyange zvazvo machubhu ekudzivirira eNSiC thermocouple angave nekudyara kwakawanda kwekutanga kupfuura dzimwe nzira dzechinyakare, hupenyu hwawo hwekushanda kwenguva refu (makore 2-5 mumamiriro ezvinhu akaoma) uye zvinodiwa zvishoma zvekugadzirisa zvinopa kuchengetedza kwakakosha kwenguva refu. Nekuderedza kuwanda kwekutsiva thermocouple uye nguva yekushanda kwekugadzira, NSiC inoderedza mari yako yese yekuva muridzi (TCO) uye inowedzera kudzoka kwako pakudyara (ROI). Kune mafekitori eindasitiri ari kutsvaga kuvandudza mashandiro, iyi isarudzo yakangwara, isingazombofi yakakunakira mune ramangwana.
Mashandisirwo Akakosha: Kwatinowana NSiC Thermocouple Protection Tubes
Machubhu ekudzivirira eNSiC thermocouple akagadzirirwa maindasitiri uko kuvimbika kwethermocouple kusingakurukurwe. Heano mashandisirwo akanakisa aanoita:

Sei Uchifanira Kusarudza Machubhu Edu Ekudzivirira eNSiC Thermocouple?
KuShandong Robert, isu tine hunyanzvi mukugadzira machubhu ekudzivirira eSilicon Nitride Bonded Silicon Carbide Thermocouple akagadzirwa kuti asangane nezvinodiwa zvekuyera tembiricha yeindasitiri. Zvigadzirwa zvedu zvinopa:
Kuenderana Kwakakwana kweThermocouple:Inowanikwa muhukuru (OD 8–50 mm, kureba 100–1,800 mm) uye magadzirirwo (akatwasuka, akarukwa, akaputirwa) kuti akwane mhando dzese dze thermocouple (K, J, R, S, B).
Uinjiniya Hwakarurama:Chubhu yega yega inogadzirwa nemidziyo yakasimba kuti ive nechokwadi chekuti inokwana zvakanaka, kudzivirira kubuda kwemhepo uye kudzivirira thermocouple yako.
Kuedzwa Kwemhando Yepamusoro:Chubhu yega yega inoedzwa zvakasimba kuti ione kana iri yakasimba, yakasimba, inodzivirira ngura, uye kuti inoshanda sei pakupisa.
Rutsigiro Rwepasi Pose:Tinopa rubatsiro rwekukurumidza, kubvunzana nezvehunyanzvi, uye sevhisi yekupedza kutengesa kuti tikubatsire kubatanidza machubhu edu mumabasa ako zviri nyore.
Wagadzirira Kudzivirira Thermocouples Yako & Kugadzirisa Maitiro Ako?
Usarega machubhu ekudzivirira asina kunaka achikanganisa mashandiro e thermocouple yako kana kuti mari yako. Simudzira kuSilicon Nitride Bonded Silicon Carbide Thermocouple Protection Tubes kuti ugare kwenguva yakareba, uwane ruzivo rwakarurama rwekupisa, uye mitengo yekuchengetedza yakaderera.
Tibatei nhasi kuti muwane sampuro yemahara, mutengo wakagadzirwa, kana kubvunzana nehunyanzvi. Ngatikubatsirei kuchengetedza mashandiro enyu eindasitiri achishanda zvakanaka—nedziviriro yakavimbika yethermocouple iri pamusika.
