Silicon Nitride Bonded Silicon Carbide Thermocouple Protection Tube: Ultimate Shield yo gupima ubushyuhe bwinganda

Thermocouples ninkingi yo kugenzura ubushyuhe mubikorwa bitagira ingano - kuva gushonga ibyuma kugeza synthesis. Nyamara, imikorere yabo nigihe cyo kubaho biterwa ahanini nikintu kimwe gikomeye: umuyoboro urinda. Mu nganda zikabije z’inganda, imiyoboro gakondo irinda thermocouple (ikozwe mu cyuma, alumina, cyangwa karubide nziza ya silicon) akenshi inanirwa kwihanganira ubushyuhe bukabije, itangazamakuru ryangirika, cyangwa ibice byangiza. Ibi biganisha kubantu benshi basimbuza thermocouple, amakuru yubushyuhe budahwitse, hamwe nigihe gito cyo gukora.

Niba urambiwe gutandukana na thermocouple kwizerwa,Silicon Nitride Bonded Silicon Carbide (NSiC) Ibirindiro bya Thermocoupleni umukino uhindura igisubizo ukeneye. Yashizweho kugirango irinde thermocouples mubihe bisabwa cyane, umuyoboro wa NSiC uremeza ko ubushyuhe burigihe, burigihe mugihe ubuzima bwa serivisi bwibikoresho byawe bipima.

Impamvu Silicon Nitride Ihambiriye Silicon Carbide Yihagararaho Kurinda Thermocouple

Imiyoboro irinda Thermocouple isaba uburinganire bwihariye bwimiterere: kurwanya ubushyuhe, kurwanya ruswa, imbaraga za mashini, hamwe nubushyuhe bwumuriro. NSiC ni indashyikirwa muri utwo turere twose, iruta ibikoresho gakondo muri buri bipimo by'ingenzi:

1. Kurwanya Ubushyuhe bukabije Kurwanya Kutumva

Thermocouples mu nganda nko gukora ibirahuri cyangwa guta ibyuma bikora mubushyuhe burenga 1.5 ° C. Imiyoboro yo gukingira ya NSiC ikora ibi byoroshye - yirata ubushyuhe bukomeza bukora bugera kuri 1,600 ° C (2,912 ° F) hamwe nigihe gito cyo kurwanya 1,700 ° C (3,092 ° F). Bitandukanye n'umuyoboro w'icyuma uhindura cyangwa ushonga, cyangwa umuyoboro wa alumina ucika munsi yubushyuhe bwumuriro, NSiC ikomeza ubusugire bwimiterere nubwo haba ihindagurika ryubushyuhe bwihuse. Ibi bivuze ko thermocouple yawe ikomeza kurindwa, kandi amakuru yubushyuhe bwawe akomeza kuba ukuri - nubwo ubushyuhe bwaba bumeze bute.

2. Kurwanya Ruswa Kurwanya Kurwanya Itangazamakuru Ritera

Inganda zikora inganda akenshi zerekana ubushyuhe bwa metero (aluminium, zinc, umuringa), aside aside / alkaline, cyangwa imyuka yangiza (dioxyde de sulfure, chlorine). Ubwinshi bwa NSiC`, nitride-ihuza imiterere ikora inzitizi itambuka kurwanya ibyo bintu. Bitandukanye na karubide ya silicon nziza, ikunda kwibasirwa nubushyuhe bwo hejuru bwubushyuhe bwo hejuru, NSiC` idasanzwe yihariye yongerera imbaraga okiside-ituma thermocouple yawe iguma ikingira ruswa kumyaka. Ibi nibyingenzi mubisabwa nko gutunganya imiti, gutwika imyanda, hamwe na bateri ya synthesis.

3. Imbaraga zidasanzwe za mashini zo kwihanganira kwambara & Ingaruka

Thermocouples mu nganda za sima, sitasiyo y’amashanyarazi, cyangwa ibikoresho bitunganya amabuye y'agaciro ihura n’iterabwoba rihoraho: ivumbi ryangiza, ibice biguruka, ningaruka za mashini. Imiyoboro yo gukingira ya NSiC yubatswe kugirango irwanye izo mbogamizi, ifite imbaraga zoroshye za MPa zirenga 300 hamwe na Vickers ikomeye (HV10) ya 1.800. Ibi bituma bakomera inshuro 3-5 kurenza imiyoboro gakondo, bikagabanya gukenera gusimburwa kenshi. Kubikorwa byawe, ibi bisobanurwa mugihe gito cyo hasi, amafaranga yo kubungabunga make, hamwe nibikorwa byizewe bya thermocouple.

4. Ibyiza byubushyuhe bwiza kubisoma byihuse, Gusoma neza

Agaciro ka thermocouple kari mubushobozi bwayo bwo gusubiza vuba ihinduka ryubushyuhe. Ubushuhe bwa NSiC` (60-80 W / (m · K)) burenze kure ubw'umubyimba wa alumina cyangwa ibyuma, bituma ubushyuhe bwihuta buva mubikorwa bugana ihuriro rya thermocouple. Ibi byemeza ko thermocouple yawe itanga igihe-nyacyo, amakuru yukuri-yingirakamaro mugukomeza kugenzura ibikorwa hamwe nubwiza bwibicuruzwa. Byongeye kandi, coefficient ya NSiC` yo hasi yo kwagura ubushyuhe (3.5-4.5 × 10⁻⁶ / ° C) igabanya imihangayiko yubushyuhe, ikarinda ibice bishobora guhungabanya ukuri gupima.

5. Igiciro-Cyiza Kuramba Kubiciro Byose byo gutunga

Mugihe NSiC irinda amashyanyarazi irashobora kugira ishoramari ryambere kuruta amahitamo gakondo, ubuzima bwabo burambye (imyaka 2-5 mubihe bibi) hamwe no kubungabunga bike bikenera kuzigama igihe kirekire. Mugabanye inshuro nyinshi zo gusimbuza thermocouple hamwe nigihe cyo gukora, NSiC igabanya igiciro cyawe cyose cya nyirubwite (TCO) kandi ikazamura inyungu zishoramari (ROI). Ku nganda zinganda zishaka kunoza imikorere, ubu ni amahitamo meza, azaza-ahazaza.
