Yuav ua li cas txiav txim qhov zoo ntawm ib qho - xaus hluav taws xob cua sov caij?

Kev txiav txim siab qhov zoo ntawm ib qho - lub taub hau hluav taws xob cua sov lub taub hau yuav tsum xav txog cov ntsiab lus tseem ceeb xws li cov khoom siv, kev tsim khoom, kev ua haujlwm, kev nyab xeeb, thiab ntawv pov thawj. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum xav txog cov khoom siv xws li lub tshuab rhaub dej, lub tshuab kas fes, thiab qhov cub, qhov kev txiav txim siab tshwj xeeb rau txhua daim ntawv thov yog qhov tseem ceeb kom tsis txhob cuam tshuam rau cov neeg siv kev paub thiab kev nyab xeeb vim muaj teeb meem zoo. Cov kev sib cais hauv qab no ntawm qhov tseem ceeb ntawm qhov loj me muab cov lus qhia siv tau rau kev xaiv.

Cov khoom siv yog qhov tseem ceeb ntawm kev txiav txim siab lub neej thiab kev ruaj ntseg. Rau cov cua sov hlau, ua qhov tseem ceeb nickel-chromium alloys (xws li Cr20Ni80) lossis hlau-chromium- aluminium alloys (xws li 0Cr25Al5). Cov ntaub ntawv no muaj kev tiv thaiv ruaj khov, siab -kub tsis kam, thiab oxidation tsis kam, tiv thaiv kev ua haujlwm degradation ntev - siv sijhawm ntev. Cov khoom lag luam tsis zoo feem ntau siv cov hlau zoo tib yam los yog qis- cov khoom siv purity, uas ua rau oxidation thiab burnout ntawm qhov kub thiab txias. Lub casing sab nrauv yuav tsum tsim nyog rau daim ntawv thov: rau cov dej-txog daim ntawv thov xws li lub tshuab rhaub dej, xaiv 304/316 stainless hlau los tiv thaiv dej kais dej; rau siab-kub daim ntawv thov xws li qhov cub, siv cov tuab stainless hlau los yog siab{19}} kub alloys kom tsis txhob deformation saum 500℃. Sab hauv rwb thaiv tsev muab tub lim yuav tsum siab -purity magnesium oxide hmoov rau zoo heev rwb thaiv tsev thiab thermal conductivity; cov khoom tsis zoo siv impurities nyob rau hauv lub muab tub lim, uas yuav ua rau tsis zoo rwb thaiv tsev los yog to.

Kev tswj hwm qib zoo yog xav txog cov ntsiab lus ntawm cov khoom siv tes ua haujlwm, uas tuaj yeem txiav txim siab los ntawm cov tsos thiab kev tshuaj xyuas yooj yim. Hais txog qhov tsos, siab- cov khoom zoo muaj qhov du, burr-dawb plhaub, tsis zoo thiab tag nrho cov welds, thiab cov qauv ntshiab ntawm cov threaded installation qhov chaw; Cov khoom lag luam tsis zoo feem ntau muaj lub plhaub ntxhib, tsis sib xws welds, thiab tej zaum yuav deformed lossis muaj cov xim pleev xim. Cov txheej txheem sealing yog qhov tseem ceeb; siab- cov khoom zoo siv siab - kub sealant los yog vuam rau sealing, ua rau lawv tsis muaj dej thiab ya raws- pov thawj; Tom qab sealing cov terminals, ib qho kev sim immersion tuaj yeem ua tau los xyuas seb qhov muaj peev xwm to. Cov hlau cua sov yuav tsum raug mob sib npaug thiab nruj nrog qhov sib txawv kom ntseeg tau tias cov cua sov ua kom zoo sib xws; Cov khoom lag luam tsis zoo muaj qhov xoob winding thiab qhov tsis sib xws, yooj yim ua rau hauv cheeb tsam overheating thiab burnout.

Kev ua tau zoo ncaj qha cuam tshuam qhov zoo, uas tuaj yeem ntsuas lossis txheeb xyuas los ntawm kev kuaj xyuas qhov ntsuas. Hais txog lub zog ruaj khov, siab - cov khoom lag luam zoo muaj qhov sib txawv ntawm lub zog tiag tiag ntawm Tsawg dua lossis sib npaug li ± 5% los ntawm tus nqi nominal, thiab cov cua sov tsis sib xws; siv lub ntsuas hluav taws xob los ntsuas, qhov sib txawv ntau dhau qhia tias muaj teeb meem nrog cov khoom siv lossis kev ua haujlwm. Kev tswj qhov kub thiab txias yog qhov tseem ceeb rau cov tshuab kas fes thiab qhov cub- cov qauv tshwj xeeb; siab- cov khoom zoo kub sai sai (mus txog qhov ntsuas kub li ntawm 30 vib nas this rau lub tshuab kas fes) thiab ua tiav ± 1℃qhov kub thiab txias tswj nrog lub ntsuas kub; Cov khoom lag luam qis qis qis qis qis thiab hloov pauv tau zoo heev, cuam tshuam rau kev siv tau. High-kub- cov qauv tshwj xeeb yuav tsum tiv taus qhov ntsuas kub siab yam tsis muaj lub zog loj. Discoloration, deformation, los yog poob sai sai ntawm lub hwj chim thaum lub sij hawm ntev -lub sij hawm siab - ntsuas kub qhia tau tias tsis zoo.

Kev tiv thaiv kev nyab xeeb thiab ntawv pov thawj yog qhov tseem ceeb. High- cov khoom lag luam zoo yuav tsum muaj cov qauv kev tiv thaiv kev kub hnyiab, overheating, thiab to: dej rhaub- cov qauv tshwj xeeb yuav tsum muaj qhov ntsuas dej tsis zoo ntawm ntau dua lossis sib npaug ntawm IPX4, thiab qhov cub- cov qauv tshwj xeeb yuav tsum tau nruab nrog lub fuse overheat. Txheeb xyuas cov ntawv pov thawj zoo xws li 3C thiab IEC; reputable manufacturers yuav tsum muab cov ntaub ntawv xeem thiab ntawv pov thawj kom meej meej hais txog kev nyab xeeb tsis; cov khoom uas tsis muaj ntawv pov thawj ua rau muaj kev pheej hmoo loj. Tsis tas li ntawd, cov khoom lag luam muaj koob npe muaj kev qhia dav tom qab- kev muag khoom thiab kev lav phib xaub, thaum cov khoom lag luam tsis zoo feem ntau tsis muaj tom qab- muag kev txhawb nqa, ua rau nws nyuaj rau nrhiav kev daws teeb meem. Hauv kev xaus, kev ntsuam xyuas dav dav raws li ntau qhov ntev thiab cov cuab yeej tsim nyog rau cov khoom siv hauv tsev tshwj xeeb yog tsim nyog los xaiv cov khoom ruaj khov thiab nyab xeeb.
