1. Cov khoom siv lub cev tseem ceeb yuav tsum ua raws li cov qauv hauv tebchaws.
Stainless hlau qhov chaw (cylindrical seem, conical seem, inlet / qhov hluav taws xob): yuav tsum tau ua los ntawm 304 los yog 316 stainless hlau, thiab ib daim ntawv pov thawj cov khoom yuav tsum tau muab . 316 stainless hlau muaj molybdenum, muab muaj zog corrosion kuj thiab yog haum rau acidic starch slurry ua.
Thaum txais tos, lub spectrometer tuaj yeem siv los ntsuas cov hlau muaj pes tsawg leeg kom paub meej tias cov ntsiab lus ntawm cov ntsiab lus xws li npib tsib xee, chromium, thiab molybdenum ua tau raws li cov qauv, tiv thaiv kev siv cov khoom tsis zoo.
2. Cov khoom siv hydrocyclone tube yuav tsum hnav -tiv taus thiab du.
Lub raj hydrocyclone feem ntau yog ua los ntawm hnav-resistant nylon lossis polyurethane, uas muaj qhov zoo ntawm:
Smooth nto, txo qhov kev pheej hmoo ntawm starch adhesion thiab clogging;
Superior hnav tsis kam piv rau hlau, nrog rau kev pab cuam lub neej ntawm ntau tshaj 3 xyoos.
Cov khoom tsim nyog yuav tsum tsis muaj npuas, delamination, thiab impurities. Qhov no tuaj yeem raug txiav txim thawj zaug los ntawm kev tshuaj xyuas qhov muag thiab kev kuaj tactile.
3. Cov kev xav tau zoo rau vuam thiab kev sib txuas
Tag nrho cov welds yuav tsum ua raws li cov kev cai ntawm LS/T3501.6 "Txhua yam kev mob rau cov nplej thiab roj ua Machinery - Welded Parts," thiab yuav tsum du, tsis muaj kab nrib pleb thiab slag inclusions.
Cov pob qij txha yuav tsum tau muab kaw kom nruj, tsis muaj qhov xau hauv qab 0.8MPa siab, tuaj yeem tshawb xyuas los ntawm kev ntsuas hydrostatic.
4. Kev kho deg thiab corrosion kuj
Sab hauv thiab sab nrauv yuav tsum polished (Ra tsawg dua lossis sib npaug ntawm 0.8μm) txhawm rau tiv thaiv kev loj hlob ntawm microbial thiab cov hmoov txhuv nplej siab.
Tom qab ua haujlwm tas li rau 72 teev nyob rau hauv ib puag ncig acidic (piv txwv li, qos yaj ywm hmoov txhuv nplej siab pH 4.5-5.5), qhov tsis muaj qhov pom tseeb ntawm cov ntsiab lus corrosion lossis discoloration yog xam tau.
5. Cov ntaub ntawv xeem thiab ntawv pov thawj
Reputable manufacturers yuav tsum muab:
Cov ntaub ntawv tshaj tawm (piv txwv li, SGS kuaj);
Siab hlab ntsha daim ntawv pov thawj ntawm conformity;
Kev tshuaj xyuas lub Hoobkas ua raws li JB / T 9035-2015 tus qauv.
