Minda yogwiritsira ntchito bimetallic thermometers

Bimetallic thermometer ndi mtundu wa chida choyezera kukhudzana, chomwe chili choyenera pa-kuyezera kutentha kwapamalo m'malo apakati komanso otsika kutentha. Angagwiritsidwe ntchito kuyeza mwachindunji kutentha kwa mpweya, madzi ndi nthunzi mu osiyanasiyana - 80 ~ 500 ℃. Ndi mankhwala abwino kuti alowe m'malo mwa mafakitale a mercury thermometers. Amagwiritsidwa ntchito kwambiri m'mafakitale amafuta, makampani opanga mankhwala, makina, kupanga zombo, kupanga magetsi ndi m'madipatimenti ena ofufuza zamakampani ndi sayansi. Ili ndi ubwino wopanda mercury ngozi, yosavuta kuwerenga, yokhazikika ndi zina zotero.

Mfundo ya bimetallic thermometer ndi kuyeza kutentha pogwiritsa ntchito mfundo yakuti mitundu iwiri ya mapepala ophatikizika azitsulo azinthu zosiyanasiyana amakhala ndi ma coefficients osiyanasiyana akukula kwamafuta ndi kutsika, zomwe zimapangitsa kupotoza ndikuyendetsa kupotoza kwa pointer. Mapeto amodzi a pepala la bimetal amakhazikika, ndipo mapeto ena amagwirizanitsidwa ndi shaft yozungulira. Kutentha kukasintha, pepala la bimetal limapindika mozungulira, motero limayendetsa shaft yozungulira kuti izungulire, ndipo shaft yozungulira imayendetsa cholozera kuti chisokoneze ngodya kuti iloze kufunika kwa kutentha kwa dial. Zoyambira zimakhala ndi dial, kasupe wapakona, shaft yozungulira, chinthu chozindikira kutentha, chubu choteteza, ndi zida zosiyanasiyana zokonzera. (chivundikiro cha tebulo, casing, galasi, mphete yosindikizira, gulu, pointer, kutsika kwa kasupe wa ngodya, kasupe wa ngodya, kukonza kasupe kumtunda, shaft yozungulira, chinthu chozindikira kutentha, chubu chotetezera, cholumikizira chubu, ulusi wakunja ndi kapu). Kuthamanga mwadzina nthawi zambiri kumakhala pa kutentha komwe kumagwiritsidwa ntchito, kupanikizika kosasunthika komwe chubu chotetezera chimatha kupirira popanda kusweka. Kuthamanga mwadzina sikungokhudzana ndi chitetezo cha chubu, m'mimba mwake ndi makulidwe a khoma, komanso kumagwirizana ndi njira yake yopangira, kuyika kwakuya, ndi mtundu ndi kuthamanga kwa sing'anga yoyezera. Kutalika kwa chubu choteteza cha bimetallic thermometer chomwe chimayikidwa mu sing'anga yoyezera ndikuzama kocheperako, komwe ndi kuwirikiza ka 8 m'mimba mwake mwa chubu choteteza.

Malinga ndi njira yolumikizira mbale ya pointer ya bimetal thermometer ndi chubu choteteza, bimetal thermometer imatha kugawidwa m'mitundu inayi: mtundu wa axial, mtundu wa radial, mtundu wa 135 ° wowongolera ndi mtundu wapadziko lonse lapansi.

1. Axial mtundu bimetallic thermometer: mbale ya pointer imalumikizidwa molunjika ndi chubu choteteza.
2. Radial mtundu bimetallic thermometer: mbale ya pointer imalumikizidwa limodzi ndi chubu choteteza.
3. 135 ° bimetallic thermometer: mbale ya pointer imalumikizidwa ndi chubu choteteza pa 135 °.
4. Universal bimetallic thermometer: njira yolumikizirana pakati pa mbale ya pointer ndi chubu yoteteza imatha kusinthidwa mosasamala.
