Dab tsi yog cov kev siv feem ntau rau kev ntsuas pH tus nqi ntawm cov kev daws teeb meem hauv hluav taws xob cua sov tube factories?
Teb: tus nqi pH yog qhov tseem ceeb ntawm cov tshuaj electroplating da dej thiab muaj kev cuam tshuam loj heev rau cov txheej txheem electroplating. Yog li ntawd, nws yuav tsum tsis tu ncua xyuas tus nqi pH ntawm cov tshuaj plating. Muaj ob txoj hauv kev uas feem ntau siv los ntawm cov chaw tsim khoom los txiav txim siab pH tus nqi ntawm cov kev daws teeb meem:
(1) Kev xeem ntawv txoj kev: Txiav txim siab pH tus nqi ntawm cov tshuaj los ntawm kev sib piv cov xim hloov ntawm daim ntawv xeem nrog tus paub pH xim qauv. Nws qhov zoo dua yog qhov yooj yim thiab yooj yim; Qhov tsis zoo yog qhov yuam kev loj heev. Qhov no yog txoj kev siv dav tshaj plaws hauv kev tsim khoom txhua hnub hauv factories.
(2) PH tester: Raws li qhov concentration ntawm hydrogen ions, muaj peev xwm sib txawv yog tsim los ntawm hydrogen electrode thiab muaj peev xwm sib txawv ntawm tus qauv electrode, thiab kev nyeem ntawv yog tso tawm ntawm potentiometer. Qhov kom zoo dua yog qhov raug siab; Qhov tsis zoo yog qhov kev sim ntau dua.
44. DC fais fab mov yog dab tsi?
Teb: Direct tam sim no yog qhov nruam ntws ntawm electrons nyob rau tib txoj kev ntawm qhov zoo thiab tsis zoo electrodes. Lub zog hluav taws xob siv hauv electroplating yog DC, nrog rau qhov hluav taws xob feem ntau ntawm 6 txog 12 volts. Vim qhov tsis tshua muaj hluav taws xob, nws tsis tuaj yeem muab los ntawm cov kab hluav taws xob sab nraud. Txoj kev niaj zaus tau txais cov khoom siv tam sim no yog 1) lub tshuab hluav taws xob ncaj qha; (2) Rectifier; (3) Roj teeb.
45. Yuav ua li cas ammeters thiab voltmeter txuas?
Teb: Ib qho ammeter, tseem hu ua ammeter, yog ib qho cuab yeej uas qhia txog tus nqi tam sim no dhau los ntawm Circuit Court. Ib qho ammeter nrog qhov ntsuas me me feem ntau tuaj yeem txuas ncaj qha rau hauv series rau hauv Circuit Court, thaum cov loj dua (siab dua 30 amperes) xav tau ib qho shunt kom txuas nrog rau hauv lub voj voog. Lub ammeter txuas nrog rau ob qhov kawg ntawm shunt. Tab sis qee qhov 5-ampere ammeters tseem xav tau qhov sib piv shunt. Voltmeter, uas yog, voltmeter, ntsuas qhov hluav taws xob thiab feem ntau txuas nrog cov khoom thauj. Ntev npaum li nws ob txoj hlua txuas txuas rau ntawm ob tug ncej ntawm lub voj voog, kev nyeem ntawv tuaj yeem qhia tau. Thaum txuas cov tam sim no thiab voltmeter, xyuam xim rau qhov polarity thiab ntau yam.
