Minda yekushandiswa kwebimetallic thermometers

Bimetallic thermometer imhando yekuyera yekuyeresa chiridzwa, chakakodzera pa-saiti kuyerwa kwetembiricha munzvimbo yepakati uye yakaderera tembiricha. Inogona kushandiswa kuyera zvakananga tembiricha yegasi, mvura uye chiutsi mumhando ye - 80 ~ 500 ℃. Icho chigadzirwa chakanakira kutsiva maindasitiri emercury thermometers. Inoshandiswa zvakanyanya mu petroleum, indasitiri yemakemikari, michina, kuvaka ngarava, kugadzirwa kwemagetsi uye mamwe maindasitiri uye madhipatimendi ekutsvagisa kwesainzi. Iyo ine zvakanakira pasina mercury hazard, iri nyore kuverenga, yakasimba uye zvichingodaro.

Musimboti weiyo bimetallic thermometer ndeyekuyera tembiricha nekushandisa musimboti wekuti marudzi maviri esimbi anoumbwa mapepa emhando dzakasiyana ane akasiyana coefficients ekuwedzera kwekupisa uye kuderera, zvichikonzera kukanganisa uye kutyaira iyo pointer deflection. Imwe mugumo webhimetal sheet yakagadziriswa, uye imwe mugumo yakabatanidzwa kune shaft inotenderera. Kana tembiricha yachinja, bimetal sheet rinomonyoroka axially, zvichibva zvafambisa shaft inotenderera kuti itenderere, uye shaft inotenderera inotyaira chinongedzo kuti chitenderere kona kunongedza kukosha kwetembiricha pane dial. Chimiro chekutanga chine dial, chitubu chekona, shaft inotenderera, tembiricha inonzwa chinhu, chubhu yekudzivirira, uye akasiyana ekugadzirisa. (chifukidziro chetafura, casing, girazi, mhete yekuisa chisimbiso, pani, pointer, kona chitubu chakadzika kugadzirisa, kona chitubu, kona chitubu chekumusoro kugadzirisa, inotenderera shaft, tembiricha inonzwa chinhu, yekudzivirira chubhu, yekudzivirira chubhu yekubatanidza, yekunze tambo uye cap). Iyo yekumanikidza yezita kazhinji iri pane yakataurwa tembiricha yekushanda, iyo static pressure iyo inodzivirira chubhu inogona kumira pasina kutyora. Iyo yekumanikidza yezita haina hukama chete neyekudzivirira chubhu zvinhu, dhayamita uye ukobvu hwemadziro, asi zvakare ine chekuita neiyo nzira yekuisa, kudzika kwekuisa, uye mhando uye kuyerera kweyepakati yakayerwa. Kureba kwechubhu inodzivirira yebimetallic thermometer inopinzwa mukati yakayerwa hudzamu hudiki hwekupinza, iyo inopeta ka8 dhayamita yechubhu inodzivirira.

Zvinoenderana negwara rekubatanidza kweiyo pointer plate ye bimetal thermometer uye yekudzivirira chubhu, bimetal thermometer inogona kupatsanurwa kuita mhando ina: axial type, radial type, 135 ° kutungamira mhando uye universal type.

1. Axial mhando bimetallic thermometer: iyo pointer plate yakabatana yakatwasuka neiyo inodzivirira chubhu.
2. Radial type bimetallic thermometer: iyo pointer plate yakabatana mukufambirana nechubhu inodzivirira.
3. 135 ° bimetallic thermometer: iyo pointer plate yakabatana kune inodzivirira chubhu pa135 °.
4. Universal bimetallic thermometer: iyo yekubatanidza kona pakati peinongedza ndiro uye inodzivirira chubhu inogona kugadziriswa zvisina tsarukano.
