Hauv cov ntawv thov xav tau kev tiv thaiv corrosion hnyav lossis kev huv huv, nruab nrab - qhib lub twj tso kua mis yog tsim los nrog cov yam ntxwv tshwj xeeb. Lub axially split casing tso cai rau kev nkag mus rau txhua qhov chaw ntub dej, qhov tseem ceeb rau kev tu huv hauv cov zaub mov lossis chaw tshuaj. Qhov ob -suction tsim inherently muab cov dej qis tshaj tawm thiab maj mam tuav, ua rau nws zoo tagnrho rau shear- cov khoom rhiab heev. Cov qauv tsim niaj hnub no muaj peev xwm rov qab rub- tawm lub peev xwm ua ke nrog cov kab sib cais, txo qis sijhawm. Lwm cov nta muaj xws li dej yaug- txuas txuas txhawm rau tshem tawm cov kab mob uas tuaj yeem loj hlob, polished nto tiav (Ra < 0.8 μm), thiab cov khoom ntim loj loj kom haum rau siab -kev ua tau zoo ntawm cov tshuab foob. Cov twj no kuj ua tau zoo ntawm kev tuav cov kua dej uas muaj cov khoom muag muag lossis cov khoom siv lead ua vim tias qhov qhib ntawm ob -suction impeller txo qhov kev pheej hmoo ntawm txhaws.
Kev xaiv khoom
Cov dej num huv huv thiab corrosive yuav tsum tau siab -qib alloys thiab tsis yog -hlau coatings. Cov khoom siv tshaj plaws yog316L stainless hlau(tsawg carbon rau weldability thiab corrosion kuj), feem ntau nrog electropolished nto. Rau cov xov xwm corrosive hnyav xws li cov kua qaub los yog chlorides,Hastelloy C-276los yogTitanium Qib 2yog teev. Hauv cov nroj tsuag desalination,Super Duplex (UNS S32750)muab zoo heev tsis kam mus rau chloride kev nyuaj siab corrosion cracking. Tsis yog-cov kev xaiv hlau muaj xws li polypropylene lossis PVDF casings rau qis -siab acid tuav. Elastomers yuav tsum yog FDA- ua raws, siv FKM (Viton) lossis EPDM, thaum silicone lossis PTFE siv rau siab - dej huv.
Siv Tau Kev Lag Luam
Covtshuajkev lag luam siv cov twj tso kua mis no rau WFI (Dej rau Txhaj) kev ncig thiab tsis hloov pauv hloov pauv.Khoom noj thiab dej hauscov ntawv thov suav nrog cov kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, thiab cov khoom siv mis nyuj uas huv huv - hauv - qhov chaw (CIP) niaj hnub.Desalination nroj tsuagcia siab rau corrosion-resistant nruab nrab- qhib lub twj tso kua mis rau rov qab osmosis pub thiab brine hloov. Covchemical uakev lag luam siv lawv los tuav nruj acids, bases, thiab cov kuab tshuaj.Microelectronicsmanufacturing kuj nyob ntawm lawv rau ultrapure dej tshuab. Txhua qhov chaw uas cov khoom purity, corrosion kuj, thiab yooj yim soj ntsuam yog yuav tsum tau, lub twj tso kua mis no yog nyiam.
