Nruab nrab- qhib lub twj tso kua mis, tus yam ntxwv los ntawm lawv cov axially split casing tsim, tso cai rau lub twj tso kua mis qhib kab rov tav raws tus ncej centerline. Cov qauv tshwj xeeb no muab cov txiaj ntsig zoo rau kev ua haujlwm. Qhov tseem ceeb tshaj plaws yog ob npaug -suction impeller, uas sib npaug axial thrust hydraulically, tshem tawm qhov xav tau rau txoj kev sib tw bearings thiab txuas lub neej ntev. Vim tias ob sab ntawm lub impeller tau txais cov kua ib txhij, cov twj no ua haujlwm nrog cov kev cai qis Net Positive Suction Head (NPSH) thiab tsim cov nqi siab dua ntawm cov taub hau me me. Lwm qhov tseem ceeb yog qhov yooj yim ntawm kev saib xyuas: ib nrab ntawm lub casing tuaj yeem raug tshem tawm yam tsis muaj kev cuam tshuam cov kav dej, lub cev muaj zog, lossis lub hauv paus, nthuav tawm lub rotor rau kev tshuaj xyuas lossis kho. Kev ua tau zoo yog qhov cim, feem ntau tshaj 90% nyob rau hauv cov chav loj vim tias txo qis sab hauv to thiab optimized flow paths.
Kev xaiv khoom
Kev xaiv cov khoom yog nyob ntawm cov kua uas tau ntim. Rau kev huv, tsis yog - daim ntawv thov dej corrosive zoo li cov dej hauv nroog, cam khwb cia hlau nrog bronze impellers thiab stainless hlau shafts yog tus qauv, muab qhov sib npaug ntawm tus nqi thiab kev tiv thaiv corrosion. Rau siab dua los yog cov kua abrasive me ntsis, cam khwb cia steel casings yog siv. Thaum tuav cov dej hiav txwv los yog dej brackish, duplex stainless hlau (xws li, CD4MCu) los yog super austenitic stainless hlau (xws li, 904L) yog teev kom tiv taus pitting thiab chloride kev nyuaj siab corrosion. Roj Hmab-kab shafts thiab hardened hnav rings tej zaum yuav muab ntxiv rau cov kua dej nrog cov xuab zeb zoo.
Siv Tau Kev Lag Luam
Cov twj tso kua mis no tswj hwm cov dej hauv nroog thiab cov dej khib nyiab, tuav cov dej nyoos, kev kho, thiab kev faib tawm. Hauv kev lag luam dav dav, lawv ua haujlwm rau HVAC kev ncig rau cov tsev loj, cov dej ntws hauv dej, thiab cov dej thawj zaug rau cov chaw ua haujlwm. Kev lag luam chemical siv lawv rau kev hloov cov tshuaj txias, huv si, thaum lub tshuab hluav taws xob tso siab rau lawv rau kev siv cov condenser ncig thiab kev pabcuam txias ntauwd. Lawv cov qauv tsim muaj zog kuj haum rau kev tswj dej nyab thiab cov chaw tso dej.
