Kev ntsuam xyuas cov qauv rau hluav taws xob tubular rhaub
1. Lub hwj chim tawm tswv yim: Lub zog ntawm lub ntsuas hluav taws xob.
2. Kev ntsuas hluav taws xob lub zog:
a. Lub zog hluav taws xob nyob hauv lub xeev txias: yuav tsum muaj peev xwm tiv taus 50Hz, 1min tiv taus voltage, txiav tawm tam sim no 5mA, tsis muaj kev tawg, cuam tshuam kev tshwm sim.
Rated voltage Kev ntsuas voltage 250V 1250V
b. Hluav taws xob muaj zog ntawm kev ua haujlwm kub: tiv taus 50Hz, 1min tiv taus voltage, txiav tawm tam sim no 5mA, tsis muaj kev tawg, cuam tshuam kev tshwm sim.
Rated voltage Kev ntsuas voltage 250V 1000V
3. Xau tam sim no nyob rau qhov ntsuas kub ua haujlwm: Nyob rau hauv qhov xwm txheej ntawm qhov tso tawm kom sov txaus, lub tshuab hluav taws xob cua sov tau nkag nrog 1.15 npaug ntawm lub zog ntsuas, thiab cov xaim tawm tam sim no yog 0.5m A.
4. Kev kuaj dhau los: nyob rau qhov xwm txheej ntawm kev tso tawm cua sov txaus, lub tshuab hluav taws xob cua sov tau ua hluav taws xob rau 1hrs ntawm 1.27 npaug ntawm lub zog ntsuas, thiab nws txias rau 0.5hrs rau chav tsev kub (yuam kom txias tau tso cai). Qhov no rov ua rau 30 mus tsis muaj kev puas tsuaj.
5. Siv qhov ntsuas qhov hluav taws xob cua sov ua kom txias (ua kom lub qhov hluav taws xob tawg): nqus cov hluav taws xob cua sov tubular hauv cov dej acidified (2% ~ 3% hydrochloric acid, sulfuric acid lossis nitric acid) rau 3hrs. Ob xaus ntawm qhov hluav taws xob cua kub tubular yuav tsum nthuav tawm yam tsawg 5 hli ntawm cov kua saum npoo. 2 ~ 3 qhov yuav tsum tau ua.
6. Sealing test: Lub raj xa hluav taws xob cua sov tau muab tso rau hauv qhov chaw ib puag ncig nrog kub txog 60 ° C thiab cov av noo ntawm 95% rau 24hrs. Tom qab muab tso rau, nws yuav tsum ua tau raws li kev ua tiav ntawm cov khoom ntawm 2 txog 3.
7. Kev sim ua lub neej: Lub tshuab hluav taws xob cua sov yog energized ntawm lub ntsuas hluav taws xob rau 1hrs nyob rau hauv kev ntsuas kub siab tag nrho, thiab txias rau 0.5hrs rau chav tsev kub (yuam kom txias tau tso cai), thiab lub sijhawm ua haujlwm nce mus txog 3000hrs.
