Kos li qub yuav tsum tau muab tso rau hauv cov xwm txheej hauv qab no:
(1) Lub twj tso kua mis nws tus kheej tsis tso cai thim rov qab vim nws cov qauv.
(2) Lub twj tso kua mis centrifugal nrog lub taub hau Ntau dua lossis sib npaug li 25m.
(3) Cov txheej txheem tsis tso cai rau qhov nruab nrab ntws rov qab mus rau sab nqus ntawm lub twj tso kua mis.
Cov xwm txheej hauv qab no tsis tas yuav tsum tau kuaj lub valve:
(1) Rau cov twj hloov pauv uas nws qhov nruab nrab muaj cov khoom siv thiab ua rau crystallization.
(2) Lub twj tso kua mis nrog ko taw valve nyob rau sab suction.
(3) Lub twj tso kua mis nws tus kheej tsis muaj kev txwv rau kev tig rov qab thiab lub twj tso kua mis centrifugal muaj lub nqa<25m.
(4) Lub rotating ib feem ntawm lub twj tso kua mis yog nruab nrog flywheel nyhuv Cheebtsam, xws li enlarged couplings, flywheel Cheebtsam, thiab lwm yam.
Installation ntawm lub twj tso kua mis qhov hluav taws xob check valve
(1) Qhov ncaj-txog nqa lub tshev valve yuav tsum tau ntsia rau ntawm kab rov tav raj; ntsug nqa check valve yuav tsum tau ntsia rau ntawm txoj kab ntsug, thiab qhov nruab nrab ntws los ntawm hauv qab mus rau saum.
(2) Lub viav vias kos li qub feem ntau tau teeb tsa ntawm cov kav dej kab rov tav: kos li qub nrog txoj kab uas hla ntawm DN ~ 80mm tuaj yeem ntsia tau rau ntawm cov kav dej ntsug lossis sab saud.
(3) Txij li thaum lub pob valve tau yooj yim puas lawm, daim tshev valve yuav tsum tau muab ntsia ze rau ntawm lub qhov hluav taws xob lub twj tso kua mis, thiab lub qhov hluav taws xob txiav tawm (feem ntau yog lub rooj vag valve lossis pob valve) yuav tsum tau muab ntsia saum lub pob valve txhawm rau tswj xyuas.
(4) Txhawm rau ua kom lub siab nyem ua ntej disassembly ntawm daim tshev valve, yog tias daim tshev valve nws tus kheej tsis muaj lub tshuab ntxuav tais diav, lub tshuab ntxuav kom huv yuav tsum tau nruab nruab nrab ntawm daim tshev valve thiab txiav tawm valve.
