1. Tshawb xyuas cov ntaub ntawv pov thawj cov ntaub ntawv
Thov tus neeg muag khoom los muab cov ntaub ntawv qhia txog cov khoom siv hlau tsis zoo (xws li SGS kuaj) kom paub meej tias lub cev tseem ceeb yog ua los ntawm 304 lossis 316 stainless hlau. Ua tib zoo saib xyuas kom paub tseeb tias cov nickel (Ni), chromium (Cr), thiab molybdenum (Mo) cov ntsiab lus raws li cov qauv.
Xyuas seb lub raj hydrocyclone yog nrog los ntawm cov lus piav qhia ntawm hnav-cov ntaub ntawv nylon lossis polyurethane los tiv thaiv kom tsis txhob muaj cov yas tsis zoo sib xyaw.
2. Ua Kev Ntsuas Cov Khoom Siv Siv Spectrometer
Siv lub portable X-ray fluorescence spectrometer (XRF) rau qhov tsis yog-kev kuaj xyuas cov khoom siv cov vuam thiab lub tog raj kheej kom paub qhov sib npaug ntawm cov hlau.
Yog tias qhov txawv txav siab manganese (Mn) cov ntsiab lus thiab cov ntsiab lus nickel thiab chromium tsawg, nws yuav yog 201 stainless hlau siv los hloov, thiab qhov no suav tias tsis tsim nyog.
3. Surface Quality thiab txheej txheem tshuaj xyuas
Sab hauv phab ntsa yuav tsum du, tsis muaj burrs, npuas, thiab tawg. Lub Ra nto roughness yuav tsum tsawg dua los yog sib npaug rau 0.8μm, uas tuaj yeem soj ntsuam los ntawm kev kov thiab kev soj ntsuam nrog lub iav magnifying.
Welds yuav tsum ua raws li tus qauv LS/T3501.6, ua kom du, nruam, thiab tsis muaj qhov tsis xws luag xws li slag inclusions thiab tsis tiav fusion.
4. Sealing thiab Pressure Testing: Ua ib qho kev ntsuam xyuas hydrostatic ntawm 0.8 MPa rau 10 feeb, xyuas tag nrho cov kev sib txuas rau kev xau thiab deformation.
Yog tias pom cov pob qij txha los yog xoob xoob, nws qhia tias cov khoom siv tsis txaus lossis kev ua haujlwm tsis zoo.
5. Corrosion Resistance Simulation Test: Muab cov qauv tso rau hauv cov tshuaj acidic nrog pH 4.5–5.5 rau 72 teev, soj ntsuam cov xim, pitting, thiab intergranular corrosion.
Tsim nyog 316 stainless hlau yuav tsum tsis pom tseeb cov cim corrosion.
6. Wear Resistance Verification: Ua ib qho kev ntsuam xyuas xuab zeb thiab gravel erosion ntawm cov phab ntsa sab hauv ntawm lub raj hydrocyclone kom simulate ntev - lub sijhawm ua haujlwm thiab xyuas qhov hnav qhov tob.
Kev coj tus nqi siab - zoo polyurethane lossis nylon raj yuav tsum tsawg dua 0.02 hli / xyoo.
