Nchifukwa chiyani thermocouple imafunika chiwongola dzanja chozizira?

ThMa ermocouple amagwiritsidwa ntchito kwambiri ngati zinthu zoyezera kutentha m'mafakitale ndi sayansi chifukwa cha kulimba kwawo, kutentha kwakukulu, komanso nthawi yofulumira kuyankha. Komabe, vuto lofala ndi ma thermocouple ndikufunika kobwezeretsanso malo ozizira.. Thermocoupleimapanga magetsi ofanana ndi kusiyana kwa kutentha pakati pa malekezero ake oyezera (malekezero otentha) ndi malekezero ake oyezera (malekezero ozizira). Malo oyezera nthawi zambiri amakhala pamalo olowera a chida choyezera, ndipo kutentha kwake kumatha kusinthasintha chifukwa cha nyengo. Kusintha kumeneku kwa kutentha kwa malo ozungulira ozizira kungayambitse zolakwika pakuyeza kutentha.

Kulipira kozizira kwa malo olumikizirana ndi njira yoyezera molondola kutentha kwa malo olumikizirana ndi kubweza mphamvu yake pa mphamvu ya thermocouple. Izi ndizofunikira kwambiri kuti mukwaniritse miyezo yolondola ya kutentha, makamaka pakugwiritsa ntchito komwe kumafuna kuwongolera kutentha molondola. Kugwiritsa ntchito kulipira kozizira kwa malo olumikizirana ndi .... Popanda kulipira koyenera, zolakwika zazikulu zitha kuchitika pakuwerengera kutentha, makamaka m'malo omwe kutentha kumakhala kosasunthika kumbali yozizira.

Pali njira zingapo zopezera chiwongola dzanja chozizira, njira imodzi yodziwika bwino ndikugwiritsa ntchito chowongolera chizindikiro cha thermocouple. Zipangizozi zimapangidwa kuti ziyeze kutentha kwa malo ozizira komanso kupereka chiwongola dzanja chofunikira pa kutulutsa kwa magetsi a thermocouple. Zowongolera chizindikiro zitha kugwiritsidwa ntchito ngati mayunitsi odziyimira pawokha kapena kuyikidwa mu zida zoyezera. Kuwongolera chizindikiro pafupi ndi malo ozizira kungagwiritsidwe ntchito kuchepetsa zolakwika pakuyeza kutentha kuwonjezera pa kugwiritsa ntchito chowongolera chizindikiro chodzipereka. Pogwiritsa ntchito njira zoyenera zosefera ndi kukulitsa pafupi ndi malo ozizira, kutulutsa kwa magetsi a thermocouple kumatha kusinthidwa kuti kuchepetse zotsatira za kusintha kwa kutentha kwa malo ozizira.

Shanghai Wangyuan Instruments of Measurement Co., Ltd. ndi kampani yaku China yodziwika bwino paukadaulo wowongolera njira zamafakitale ndi zinthu kwa zaka zoposa 20. Tikhoza kupereka zolondola komanso zodalirika.zotumizira kutenthandi zinthu zozindikira za malo ozizira zomwe zimathandizira thermocouple komansochitetezo chanzeru chotchingayokhala ndi ntchito yodziyimira yokha yolumikizirana ndi malo ozizira. Musazengereze kulumikizana nafe kuti mudziwe zambiri.
