Nws yog ib qho tseem ceeb uas koj tsis txhob cia lub twj tso kua mis cavitate, vim tias lub ntsej muag foob yuav qhib thiab tej zaum yuav puas.Dej rauj kuj tuaj yeem tshwm sim yog tias lub zog poob rau lub twj tso kua mis thaum nws khiav, yog li ua kev tiv thaiv kom tsis txhob muaj teeb meem no.
Muaj ob peb yam uas yuav tsum tau kuaj xyuas thaum npaj lub twj tso kua mis rau lub foob, suav nrog;tias qhov loj ntawm lub twj tso kua mis / lub cev muaj zog pedestal yog tsawg kawg yog tsib npaug ntawm qhov loj ntawm cov khoom siv zaum ntawm nws;tias muaj kaum txoj kab uas hla ntawm cov yeeb nkab ntawm lub twj tso kua mis thiab thawj lub luj tshib;thiab hais tias lub hauv paus phaj yog theem thiab grouted nyob rau hauv qhov chaw.
Khaws qhov qhib impeller hloov kho kom txo qis kev co thiab cov teeb meem hauv kev rov ua haujlwm, xyuas kom cov bearings muaj cov lubrication zoo, thiab cov dej thiab cov khib nyiab tsis nkag mus rau hauv cov kabmob.Koj yuav tsum tau hloov cov roj los yog di ncauj seals nrog labyrinth los yog lub ntsej muag seals.
Nco ntsoov kom tsis txhob tso tawm cov kab rov ua haujlwm txuas nrog lub thawv ntim khoom, feem ntau suction recirculation yuav zoo dua.Yog hais tias lub twj tso kua mis muaj lub nplhaib, xyuas kom koj kuj xyuas lawv cov clearance.
Qhov kawg uas yuav tsum tau ua thaum npaj lub twj tso kua mis yog kom paub tseeb tias cov khoom ntub dej ntawm lub twj tso kua mis yog tsim los ntawm cov khoom siv corrosion-resistant, raws li cov tshuaj ntxuav thiab cov kuab tshuaj hauv cov kab tej zaum yuav ua rau muaj teeb meem uas tus tsim tsis tau xav txog.
Tom qab ntawd muab cov cua uas yuav nkag mus rau hauv qhov nqus ntawm lub twj tso kua mis thiab tshem tawm txhua yam uas yuav raug dai rau hauv lub volute.
Yuav ib lub foob zoo
Siv hydraulically balanced designs uas kaw ob lub siab thiab lub tshuab nqus tsev thiab yog tias koj yuav siv lub elastomer hauv lub foob, sim siv lub nplhaib o-ring.Cov no yog cov qauv zoo tshaj plaws rau ntau yam, tab sis tsis txhob cia leej twg caij nplooj ntoos hlav load lub o-ring los yog nws yuav tsis flex los yog yob raws li nws yuav tsum tau.
Koj yuav tsum tau siv cov qauv tsis-fretting foob raws li ncej fretting yog ib qho tseem ceeb ua rau tsis ua hauj lwm ntxov ntxov.
Cov ntsaws ruaj ruaj (qhov twg cov springs tsis tig nrog lub ncej) zoo dua li cov ntsaws ruaj ruaj (lub caij nplooj ntoos hlav tig) rau sealing emissions thiab lwm yam dej.Yog tias lub foob muaj qhov me me, cia lawv tawm ntawm cov kua dej los yog lawv yuav txhaws tau yooj yim.Muaj ntau ntau cov qauv tsim uas muaj qhov tsis muaj qhov thaiv no.
Lub ntsej muag dav dav yog qhov zoo heev rau lub zog radial peb pom hauv kev siv cov khoom sib tov thiab cov ntsaws ruaj ruaj uas lub cev nyob deb ntawm cov bearings.
Koj tseem yuav xav tau qee yam kev vibration damping rau qhov kub siab hlau nqus cov ntsaws ruaj ruaj vim lawv tsis muaj elastomer uas ib txwm ua haujlwm ntawd.
Siv cov qauv tsim uas khaws cov kua dej sib khi ntawm lub foob sab nraud, lossis lub zog centrifugal yuav pov cov khib nyiab rau hauv lub ntsej muag lapped thiab txwv lawv txoj kev txav thaum cov pa roj carbon hnav.Koj yuav tsum tau siv cov pa roj carbon tsis zoo rau lub ntsej muag foob vim lawv yog qhov zoo tshaj plaws thiab tus nqi tsis dhau.
Tsis tas li, nco ntsoov tias koj tuaj yeem txheeb xyuas tag nrho cov ntaub ntawv foob vim tias nws tsis tuaj yeem daws teeb meem "cov khoom tsis paub".
Tsis txhob cia tus neeg muag khoom qhia rau koj tias nws cov khoom yog tus tswv, thiab yog tias qhov ntawd yog lawv tus cwj pwm, nrhiav lwm tus neeg muag khoom lossis chaw tsim khoom, txwv tsis pub koj tsim nyog txhua yam teeb meem koj yuav muaj.
Sim kom elastomers kom deb ntawm lub ntsej muag foob.Lub elastomer yog ib feem ntawm lub foob uas yog qhov rhiab tshaj plaws rau cov cua sov, thiab qhov kub tshaj plaws ntawm lub ntsej muag.
Txhua yam khoom txaus ntshai lossis kim yuav tsum tau muab khi nrog ob lub foob.Nco ntsoov tias qhov sib npaug ntawm hydraulic yog nyob rau hauv ob qho tib si cov lus qhia los yog koj tab tom twv txiaj uas ib qho ntawm lub ntsej muag yuav qhib nyob rau hauv lub siab rov qab los yog surge.
Thaum kawg, yog tias tus qauv tsim muaj cov pa roj carbon nias rau hauv cov hlau tuav, nco ntsoov tias cov pa roj carbon raug nias thiab tsis "shrunk rau".Nias carbon yuav shear kom ua raws li qhov tsis sib xws ntawm cov hlau tuav, pab kom lub ntsej muag lapped tiaj tus.
Nruab lub foob kom raug
Cartridge seals yog tib tus qauv tsim uas ua rau kev txiav txim siab yog tias koj xav hloov lub impeller, thiab lawv yooj yim dua rau nruab vim koj tsis xav tau cov ntawv luam tawm, lossis ntsuas qhov ntsuas kom tau txais lub ntsej muag raug.
Cartridge dual cov ntsaws ruaj ruaj yuav tsum muaj lub nplhaib twj tso kua mis thiab koj yuav tsum siv cov kua dej tsis zoo (qis siab) ntawm cov ntsaws ruaj ruaj thaum twg ua tau kom tsis txhob muaj teeb meem ntawm cov khoom lag luam.
Zam txhua yam roj raws li cov kua dej tsis zoo vim cov roj tsis tshua muaj cua sov thiab tsis zoo conductivity.
Thaum txhim kho, khaws lub foob kom ze rau cov bearings li sai tau.Feem ntau yog qhov chaw txav lub foob tawm ntawm lub thawv ntim khoom thiab tom qab ntawd siv lub thawv ntim khoom rau qhov kev txhawb nqa bushing los pab kom ruaj khov ntawm cov ncej.
Nyob ntawm daim ntawv thov, koj yuav tsum txiav txim siab seb qhov kev txhawb nqa bushing no yuav tsum tau khaws cia axially.
Split seals kuj ua rau muaj kev nkag siab zoo ntawm txhua daim ntawv thov uas tsis tas yuav tsum muaj ob lub ntsaws ruaj ruaj los yog foob pob hluav taws xob foob (tshwj xeeb ntsuas hauv qhov chaw ib lab).
Split seals yog tus tsim nkaus xwb uas koj yuav tsum siv rau ntawm ob lub twj tso kua mis, txwv tsis pub koj yuav tau hloov ob lub foob thaum tsuas yog ib lub foob tsis ua tiav.
Lawv kuj tso cai rau koj hloov cov ntsaws ruaj ruaj yam tsis tas yuav ua kom rov zoo nrog lub twj tso kua mis tsav tsheb.
Tsis txhob lubricate lub ntsej muag ntawm lub installation, thiab khaws cov khib nyiab tawm ntawm lub ntsej muag lapped.Yog tias muaj cov txheej tiv thaiv ntawm lub ntsej muag foob, nco ntsoov tshem tawm nws ua ntej kev teeb tsa.
Yog tias nws yog cov roj hmab hauv qab foob, lawv yuav tsum muaj cov roj nplua nyeem tshwj xeeb uas yuav ua rau lub tshuab nqus tsev twj rau ntawm tus ncej.Nws feem ntau yog cov kua roj av, tab sis koj tuaj yeem tshawb xyuas nrog koj tus neeg muag khoom kom paub tseeb.Rubber bellows seals kuj yuav tsum tau ua kom tiav ntawm qhov tsis zoo dua li 40RMS, lossis cov roj hmab yuav nyuaj rau kev ua haujlwm ntawm cov ncej.
Thaum kawg, thaum txhim kho hauv daim ntawv thov ntsug, nco ntsoov tso lub thawv ntim khoom ntawm lub ntsej muag foob.Tej zaum koj yuav tau nruab lub qhov cua no yog tias lub twj tso kua mis tsis tau muab nws.
Ntau lub foob pob hluav taws muaj lub qhov cua uas koj tuaj yeem txuas mus rau lub twj tso kua mis los yog lwm qhov chaw qis hauv qhov system.
Saib xyuas lub foob
Cov kauj ruam kawg ntawm kev ua tiav lub neej foob zoo yog kev saib xyuas tas li.Cov ntsaws ruaj ruaj nyiam ua kom cov dej txias, huv si, lubricating kua, thiab thaum peb tsis tshua muaj ib qho los muab khi, tej zaum koj tuaj yeem siv kev tswj ib puag ncig hauv lub thawv ntim khoom kom hloov koj cov khoom rau hauv ib qho.
Yog tias koj siv lub thawv ntim khoom, nco ntsoov lub tsho huv.Condensate los yog chav dej yog cov kua dej zoo tshaj plaws los ntawm lub tsho.
Sim txhim kho cov pa roj carbon bushing nyob rau hauv qhov kawg ntawm lub thawv ntim khoom kom ua raws li lub thermal barrier uas yuav pab kom stabilize lub thawv ntim khoom kub.
Flushing yog qhov kawg ntawm kev tswj hwm ib puag ncig vim nws ua rau cov khoom lag luam dilution, tab sis yog tias koj siv lub foob raug cai koj yuav tsis xav tau dej ntau.Plaub lossis tsib nkas loos ib teev (daim ntawv ceeb toom kuv hais tias teev tsis yog feeb) yuav tsum txaus rau hom foob.
Koj yuav tsum tau khaws cov kua txav mus rau hauv lub thawv ntim khoom kom tiv thaiv kom tsis txhob muaj cua sov.Suction recirculation yuav tshem tawm cov khib nyiab uas hnyav dua li cov khoom koj tau muab khi.
Txij li qhov ntawd yog qhov feem ntau slurry mob, siv suction recirculation raws li koj tus qauv.Tsis tas li, kawm qhov twg tsis siv nws.
Kev tso tawm rov ua dua yuav tso cai rau koj kom nce siab hauv lub thawv ntim khoom kom tiv thaiv cov kua dej los ntawm vaporizing ntawm lub ntsej muag lapped.Sim tsis txhob tsom cov kab recirculation ntawm lub ntsej muag lapped, nws tuaj yeem ua rau lawv raug mob.Yog hais tias koj siv ib tug hlau bellows cov recirculation kab yuav ua raws li ib tug sandblaster thiab txiav cov nyias bellows daim hlau.
