Cov qauv kev lees paub rau cov khoom siv kho dej yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab ruaj khov ntawm kev kho dej. Lawv encompass ntau qhov ntev, aiming los tswj qhov zoo ntawm qhov chaw thiab tiv thaiv qhov system tsis ua hauj lwm los yog cov dej tsis zoo los ntawm ib feem ntawm cov teeb meem.
1. Cov Qauv Txuj Ci: Yuav tsum muaj cov khoom siv thiab cov txheej txheem
● Kev Ua Raws Li Cov Khoom Siv: Cov khoom siv kho dej yuav tsum yog ua los ntawm cov khoom tsim nyog rau hom dej kho. Piv txwv li, cov khoom siv kho cov dej haus yuav tsum tau ua los ntawm cov khoom noj- qib stainless hlau (xws li 304 lossis 316L) kom tsis txhob hnyav hlau leaching; rau kev kho cov dej khib nyiab, qhov chaw yuav tsum yog cov kua qaub thiab alkali tiv taus, xws li siv PVDF lossis fiberglass. Cov ntaub ntawv soj ntsuam cov ntaub ntawv yuav tsum raug kuaj xyuas thaum lees paub kom ua raws li cov qauv hauv tebchaws xws li GB / T 1220 (stainless steel) lossis HG / T 21539 (fiberglass).
● Machining Accuracy: Dimensional tolerances ntawm qhov chaw yuav tsum tau tswj nruj me ntsis. Piv txwv li, qhov roughness ntawm lub membrane vaj tse lub sealing nto yuav tsum tsawg tshaj li los yog sib npaug rau Ra0.8μm los xyuas kom meej lub kaw ntom ntom nrog lub membrane module; cov xov raug ntawm cov yeeb nkab sib txuas yuav tsum ua tau raws li ISO 7-1 cov qauv kom tiv thaiv kom tsis txhob tawg thaum lub sijhawm teeb tsa. Thaum lub sij hawm txais kev kuaj, random check yuav tsum tau siv cov cuab yeej xws li calipers thiab nto roughness testers.
● Structural Rationality: Cov qauv tsim yuav tsum ua raws li cov qauv hydraulic. Piv txwv li, qhov qhib qhov sib piv ntawm cov dej distributor yuav tsum sib xws (yuam kev Tsawg dua los yog sib npaug li 5%) kom tsis txhob muaj qhov luv luv hauv zos ({2}}circuiting dej ntws; lub inlet kawg ntawm lub rov qab osmosis membrane vaj tse yuav tsum tau nruab nrog ib tug baffle phaj kom txo tau cov kev cuam tshuam ntawm dej ntws ntawm lub membrane caij. Tus qauv tsim tuaj yeem txheeb xyuas tau thaum kuaj pom los ntawm kev ntsuas dej siab lossis 3D scanning.
2. Kev Kho Dej Accessory Txais Cov Qauv
● Kev Ntsuam Xyuas Kev Ua Haujlwm: Kev txheeb xyuas raws li simulated ua haujlwm tiag tiag
● Kev Ntsuas Kev Ntsuas Siab: Cov khoom siv yuav tsum tiv taus 1.5 npaug ntawm kev tsim siab (piv txwv li, yog tias qhov kev tsim siab yog 1.0 MPa, qhov kev ntsuas siab yuav tsum ncav cuag 1.5 MPa) rau 30 feeb yam tsis muaj dej los yog deformation. Piv txwv li, cov hlab ntsha siab yuav tsum tau kuaj hydrostatic raws li ASME VIII cov qauv; lub siab nkhaus yuav tsum tau sau tseg thiab lub deformation kuaj xyuas thaum txais.
● Flow Rate and Resistance Test: Filter cartridges, filters, and other accessories yuav tsum raug kuaj xyuas kom poob siab ntawm qhov ntsuas ntws. Piv txwv li, lub siab poob ntawm PP yaj- blown lim cartridge yuav tsum tsawg dua los yog sib npaug rau 0.05 MPa ntawm tus nqi ntws ntawm 10 m³ / h; Lub transmembrane siab sib txawv ntawm ib tug ultrafiltration membrane module yuav tsum tsawg tshaj li los yog sib npaug rau 0.03 MPa ntawm ib tug flux ntawm 20 L / (m²·h). Kev ntsuas qhov tseeb yuav tsum tau ua los ntawm kev siv lub ntsuas dej ntws thiab ntsuas lub siab thaum txais.
● Corrosion Resistance Test: Hlau fittings yuav tsum tau muab tso rau hauv 5% NaCl tov rau 72 xuab moos, nrog rau qhov corrosion saum npoo tsawg dua lossis sib npaug li 0.01mm / xyoo; tsis yog-cov khoom siv hlau (xws li cov kav dej PVC) yuav tsum tau muab tso rau hauv 20% H₂SO₄ daws rau 24 teev, nrog rau qhov poob qis dua lossis sib npaug li 1%. Cov qauv yuav tsum raug txiav rau metallographic tsom xam lossis ntsuas qhov sib piv thaum txais.
3. Kev Kho Dej Accessory Txais Cov Qauv
● Cov Lus Qhia Txog Kev Nyab Xeeb: Dual Protection thiab Labeling
● Kev Nyab Xeeb Hluav Taws Xob: Nyob - cov khoom siv hauv kab (xws li cov twj tso kua dej thiab cov khoom tswj) yuav tsum dhau qhov kev ntsuas kev tiv thaiv IP55, nrog cov rwb thaiv tsev tiv thaiv ntau dua lossis sib npaug ntawm 1MΩ (500V DC). Thaum kuaj pom zoo, yuav tsum siv lub megohmmeter thiab cov tshuaj tsuag uas simulating qhov chaw ntub dej.
● Kev Nyab Xeeb Kev Nyab Xeeb: Cov khoom sib hloov (xws li aerator impellers) yuav tsum tau nruab nrog kev tiv thaiv npog nrog qhov khoob tsawg dua lossis sib npaug li 5 hli; Cov hlab ntsha siab yuav tsum tau nruab nrog kev nyab xeeb li qub, thiab cov txheej txheem siab yuav tsum ua kom haum rau qhov kev tsim siab (qhov yuam kev tsawg dua lossis sib npaug li ± 3%). Thaum kuaj pom zoo, daim ntawv qhia txog kev nyab xeeb valve calibration thiab cov ntaub ntawv tiv thaiv npog lub zog yuav tsum raug txheeb xyuas.
● Labeling Integrity: Cov khoom siv yuav tsum tau sau nrog cov ntaub ntawv tseem ceeb xws li cov qauv, cov lus qhia tshwj xeeb, hnub tsim khoom, thiab kev ntsuas siab. Daim ntawv lo yuav tsum hnav- tiv taus (xws li, siv laser engraving lossis etching). Thaum lub sij hawm txais kev kuaj, daim ntawv lo yuav tsum tau so 100 zaug nrog ib tug cawv cawv los xyuas seb puas tev los yog qhov muag plooj.
