Cov teb ntawm kev siv bimetallic thermometers

Bimetallic tus pas ntsuas kub yog ib hom kev ntsuas kev sib cuag, uas yog tsim rau ntawm qhov chaw ntsuas kub hauv qhov chaw nruab nrab thiab qis. Nws tuaj yeem siv ncaj qha ntsuas qhov kub ntawm cov pa roj, kua thiab chav nyob hauv thaj tsam ntawm - 80 ~ 500 ℃. Nws yog ib qho khoom siv zoo tshaj plaws los hloov cov khoom siv mercury thermometers. Nws yog dav siv nyob rau hauv roj av, tshuaj lom neeg kev lag luam, machinery, shipbuilding, fais fab tuag thiab lwm yam industrial thiab scientific kev tshawb fawb departments. Nws muaj qhov zoo ntawm tsis muaj mercury txaus ntshai, nyeem tau yooj yim, ruaj khov thiab lwm yam.

Lub hauv paus ntsiab lus ntawm tus pas ntsuas kub bimetallic yog ntsuas qhov ntsuas kub los ntawm kev siv lub hauv paus ntsiab lus uas ob hom hlau sib xyaw cov ntaub ntawv sib txawv muaj cov coefficients sib txawv ntawm thermal expansion thiab contraction, uas ua rau distortion thiab tsav lub pointer deflection. Ib qho kawg ntawm daim ntawv bimetal yog tsau, thiab lwm qhov kawg yog txuas nrog lub rotating ncej. Thaum qhov kub thiab txias hloov, daim ntawv bimetal twists axially, yog li tsav lub rotating ncej tig, thiab lub rotating ncej tsav lub pointer deflect ib lub kaum sab xis taw tes rau qhov kub ntawm tus nqi ntawm lub dial. Cov qauv yooj yim muaj xws li dial, lub kaum sab xis caij nplooj ntoos hlav, tig ncej, ntsuas qhov ntsuas kub, lub raj tiv thaiv, thiab ntau yam khoom kho. (lub rooj npog, casing, iav, sealing nplhaib, vaj huam sib luag, pointer, ces kaum lub caij nplooj ntoos hlav qis kho, ces kaum lub caij nplooj ntoos hlav, ces kaum lub caij nplooj ntoos hlav sab sauv kho, rotating ncej, kub sensing caij, tiv thaiv tube, tiv thaiv tubing sib koom, xov sab nraud thiab lub hau). Lub siab nominal feem ntau yog nyob ntawm qhov ntsuas kub ua haujlwm, qhov siab zoo li qub uas lub raj tiv thaiv tuaj yeem tiv taus yam tsis muaj kev tawg. Lub nominal siab tsis tsuas yog hais txog cov khoom siv tiv thaiv tubing, txoj kab uas hla thiab phab ntsa thickness, tab sis kuj muaj feem xyuam rau nws txoj kev teeb tsa, qhov tob tob, thiab hom thiab ntws tus nqi ntawm qhov ntsuas nruab nrab. Qhov ntev ntawm txoj hlua tiv thaiv ntawm tus pas ntsuas kub bimetallic tso rau hauv qhov ntsuas nruab nrab yog qhov tsawg kawg nkaus ntxig qhov tob, uas yog 8 npaug ntawm txoj kab uas hla ntawm lub raj tiv thaiv.

Raws li kev sib txuas lus ntawm lub pointer phaj ntawm tus pas ntsuas kub bimetal thiab lub raj tiv thaiv, tus pas ntsuas kub bimetal tuaj yeem muab faib ua plaub hom: hom axial, hom radial, 135 ° kev taw qhia hom thiab hom universal.

1. Axial hom bimetallic tus pas ntsuas kub: lub pointer phaj txuas vertically nrog lub raj tiv thaiv.
2. Radial hom bimetallic tus pas ntsuas kub: lub phaj pointer txuas nrog rau qhov sib npaug nrog lub raj tiv thaiv.
3. 135 ° bimetallic tus pas ntsuas kub: lub phaj pointer txuas nrog lub raj tiv thaiv ntawm 135 °.
4. Universal bimetallic tus pas ntsuas kub: lub kaum sab xis sib txuas ntawm lub phaj pointer thiab cov raj tiv thaiv tuaj yeem hloov kho arbitrarily.
