Stainless hlau siab gauge corrosion precautions
Nyob rau hauv lub siab gauge txij nkawm uas yog qhov tseem ceeb heev yog lub siab gauge corrosion, stainless hlau siab gauge anti-corrosion Nco ntsoov:
1, txoj kev tawm xov xwm dav hlau, yog tias cov hlau tsis txhuam cov hlab tuaj yeem tiv thaiv 1 mus rau 2 xyoo ntawm kev txhim kho, koj tuaj yeem xaiv siv ammonia siab gauge, lub installation, lub yeeb nkab siab kom luv, tsis chwj hloov mus ntes cov tank kom tiv thaiv tsis tau .
2, yog tias cov xov xwm ntawm txoj hlua ntawm stainless hlau thiab tooj liab, lub tank tsis tuaj yeem siv los cais tawm lub tank, ntxiv cov kua dej tawm hauv lub cev uas tsis muaj corrosion-resistant. Hom kab kua dej cais tau xaiv raws li cov xwm txheej ntawm kev ntsuas, tab sis yuav tsum siv ntau tshaj rau lub hlis tsis muaj kev puas tsuaj thiab. Yog tias cov kua hluav taws xob tsis tuaj yeem siv tsis tau, siv cov roj fluorocarbon cais tawm, tab sis tus nqi tseem kim heev, yog li cov khoom siv cais ua kom me me, disassembly thiab rov qab cov roj fluorine rov siv.
3, yuav siv tau diaphragm pressure gauge, muaj molybdenum 2 titanium thiab tantalum ntsiav tshuaj, diaphragm thiab lub raj caij nplooj ntoos hlav nrog methyl silicone roj hloov siab, qhov tsawg kawg nkaus yuav ua tau 0 ~ 100kPa, yog cov ntaub ntawv diaphragm tsis rot, koj ntxiv tau ib txheej ntawm F46 (poly perfluoro ethylene propylene) zaj duab xis, tab sis qhov cuab yeej rhiab heev yog txo. F46 kuj tseem siv tau ua daim diaphragm ncaj qha, tab sis xyuam xim rau cov kab mob hauv lub nruab nrab, cov kua hloov tau cov roj fluorine, koj tuaj yeem ua ob zaug cais.
