Kuongororwa kwekushandiswa kwebimetallic sheet mune thermal protector

Chinhu chinonyanya kukosha munethermal protectorndiyo bimetal. Nhasi, ini ndichakutora kuti unzwisise kushandiswa kwebimetal mumudziviriri wekupisa.

Basa rebimetal sheet mumudziviriri wekupisa ndere: kana tembiricha yachinja, nekuti iyo yekuwedzera coefficient yedivi rekuwedzera rebimetal yakakwirira kwazvo kupfuura iyo coefficient yekuwedzera yedivi rekuwedzera, kukotama kunoitika, uye isu tinoshandisa kukotama uku. shanda. muthermal protector.

Izvo zvinopisa bimetallic raw materials yevakasiyana-siyana vanogadzira zvakangofanana, matrix isimbi nemhangura alloys, uye zvinhu zvakaita senickel nemanganese zvinowedzerwa kuti zvishandure macoefficients azvo ekuwedzera, zvichiita kuti pave nerutivi rwakakura-wekuwedzera uye mativi akaderera ekuwedzera, uye wobva waumba composite. Master alloys dzimwe nguva anowedzerwa kuitira kuti achinje resistivity yezvinhu.

Asati aunganidzathermal protector, iyo bimetallic sheet kuumba inhanho yakakosha. Kutanga, iyo inopisa bimetallic strip inoroverwa uye yakavharwa kuita sheet shape, uye yozofanoumbwa kuita disc shape. Panguva ino, dish-shaped thermal bimetal ine chiito chekugadzirisa uye kugadzirisa zvakare kupisa. Iwo makuru ma paramita ema bimetals anofanirwa kutariswa usati warova: chaiyo kukotama, elastic modulus, kuoma, dimensional kurongeka, resistivity, tembiricha yekushanda. Kutanga funga nezve tembiricha yemhando iyo bimetal sheet inogona kushandiswa mairi, uye wofunga nezve simba uye torque yechiito icho bimetal inofanira kuburitsa, uye sarudza yakakodzera chaiyo yekubhenda uye elastic modulus. Wobva wasarudza saizi, kuomarara uye elastic modulus yeinopisa bimetal yakakodzera kune yakatarisana yekuumba maitiro uye michina. Wobva wasarudza iyo yakakodzera resistivity maererano nezvino nguva zvinodiwa zvemudziviriri uye mhedzisiro yekupisa simba cavity.

Maererano neiyo bimetal's current thermal effect formula Q = ∫t0I2Rdt, zvinogona kuzivikanwa kuti kusarudza bimetal ine kukwirira kwakanyanya kunobudisa kupisa kwakawanda, kupfupisa nguva yekushanda yemudziviriri wekupisa, uye kuderedza kushandiswa kwemazuva ano. Izvo zvinopesana ndezvechokwadi kune bimetals ine kushomeka kushoma. Kupokana kwebimetal kunokonzerwa nekudzivirira, ukuru uye kukora kwechimiro.
