Kev ceev faj rau kev siv thiab khaws cia ntawm cov kav hluav taws xob cua sov

Kev ceev faj rau kev siv thiab khaws cia ntawm cov kav hluav taws xob cua sov

1. Lub raj hluav taws xob cua sov yuav tsum tau muab tso rau thiab kho kom zoo, thiab qhov chaw cua sov kom zoo yuav tsum tau muab tso rau hauv cov kua lossis cov hlau khib nyiab, thiab kev kub hnyiab yog txwv nruj heev. Thaum cov nplai lossis cov pa roj carbon deposits pom nyob rau saum npoo ntawm lub raj, lawv yuav tsum tau muab tshem tawm tam sim ntawd thiab rov siv dua kom tsis txhob cuam tshuam cov cua kub dissipation thiab shortening nws cov kev pab cuam lub neej.

2. Thaum cua sov fusible hlau los yog cov khoom nitrate, alkali, asphalt, paraffin, thiab lwm yam., qhov kev khiav hauj lwm voltage yuav tsum tau qis dua ua ntej, thiab tsuas yog tom qab nruab nrab melts nws yuav nce mus rau qhov ntsuas voltage.

3. Cov khoom raug tso cai ua haujlwm raws li cov hauv qab no: A. Qhov txheeb ze av noo ntawm huab cua yuav tsum tsis pub tshaj 95%, thiab yuav tsum tsis txhob muaj cov pa phem lossis corrosive gases. B. Lub zog ua haujlwm yuav tsum tsis pub tshaj 1.1 npaug ntawm tus nqi ntsuas, thiab cov casing yuav tsum tau ua haujlwm zoo. C. Rwb thaiv tsev tsis kam Ntau dua lossis sib npaug ntawm 1M Ω Dielectric zog: 2KV / 1min.

4. Thaum cua sov nitrate, yuav tsum ntsuas kev nyab xeeb los tiv thaiv kev tawg.

5. Thaum cua sov cua sov, cov khoom yuav tsum tau teem caij rau hauv ib tug ntoo khaub lig thiab niaj hnub yam ntxwv los muab zoo cua sov dissipation tej yam kev mob rau lub Cheebtsam thiab cia cov cua ntws mus rau tag nrho cov cua sov.

6. Cov hmoov magnesium oxide nyob rau ntawm qhov hluav taws xob hluav taws xob cua sov raj yuav tsum tau tiv thaiv los ntawm cov pa phem thiab noo noo infiltration hauv qhov chaw siv los tiv thaiv kev sib tsoo.

7. Cov khoom yuav tsum tau muab cia rau hauv qhov chaw qhuav. Yog tias cov rwb thaiv tsev tsis zoo qis dua 1M Ω vim qhov kev cia ntev ntev, lawv tuaj yeem qhuav hauv qhov cub ntawm ib ncig ntawm 200 degree lossis cua sov los ntawm kev txo qhov hluav taws xob kom txog thaum cov rwb thaiv tsev rov qab los.

8. Cov kab hluav taws xob yuav tsum tau muab tso rau sab nraud ntawm txheej rwb thaiv tsev kom tsis txhob muaj kev sib cuag nrog corrosive, explosive media, thiab ya raws; Cov hlau lead yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ntawm cov kab hluav taws xob rau lub sijhawm ntev, thiab kev siv zog ntau dhau yuav tsum tau zam thaum nruj cov hlua txuas.

Kev sib piv ntawm stainless hlau cua sov kav thiab cov kav cua sov zoo tib yam:

Stainless hlau cua sov tube: Nws muaj cov cua kub zoo, kub kub tsis kam, cov cuab yeej paub tab, thiab tus nqi qis. Cov ntsiab lus nickel nce mus txog 27%. (Cov ntsiab lus nickel yuav tsum ncav cuag 27% txhawm rau kom muaj kev hloov pauv tseem ceeb hauv kev tiv thaiv corrosion ntawm stainless hlau cua sov kav hauv qee yam xov xwm). Raws li cov ntaub ntawv, 316, 800, thiab 840 muaj zog corrosion kuj thiab kub tsis kam. 800 stainless hlau muaj txog li 30% nickel, uas tsuas yog siv rau cov ntaub ntawv tshwj xeeb.

Ordinary stainless hlau cua sov kav: Cov ntsiab lus npib tsib xee tsuas yog 24%, thiab cov ntsiab lus npib tsib xee yuav tsum ncav cuag 27% kom ua rau corrosion kuj ntawm stainless hlau cua sov kav hloov pauv hauv qee yam xov xwm. Hais txog cov khoom siv, cov ntsiab lus nickel ntawm 840 stainless hlau ncav cuag 20%, thaum cov ntsiab lus nickel ntawm 304 stainless hlau yeeb nkab tsuas yog 8%. Los ntawm tus nqi pom, siv stainless hlau 304 rau cov dej cua sov ib txwm muaj txaus.
