Dej yog ib qho chaw tseem ceeb uas feem ntau siv hauv cov txheej txheem cua txias thiab lwm yam tsis siv API. Vertical twj yog feem ntau siv vim lawv txoj kev ntseeg siab hauv kev tsim. Vertical twj tso kua mis yog cov cuab yeej tseem ceeb rau kev thauj cov dej ntws siab hauv tag nrho cov dej, petrochemical, thiab hluav taws xob tsim kev lag luam. Los ntawm kev ua kom zoo ntawm kev ua haujlwm thiab kev ua haujlwm ntawm cov twj tseem ceeb no, cov nqi khiav lag luam thiab kev saib xyuas tuaj yeem txo qis.
1. Kev ua tau zoo sib xws
Lub twj tso kua mis ntsug tau yooj yim saib xyuas thaum lub sijhawm tu txhua hnub. Qhov kev ntseeg siab ntawm lawv cov qauv tsim txhais tau hais tias lawv tsis tshua muaj kev cuam tshuam los ntawm kev saib xyuas cov xwm txheej. Txawm li cas los xij, dhau sijhawm, kev hnav thiab tsim kua muag ntawm ntau yam khoom tuaj yeem ua rau txo qis hauv kev ua haujlwm, uas tuaj yeem ua rau tsis zoo yog tias tsis tswj xyuas kom zoo.
Kev tuav hydraulic tsim rau kev siv cov xwm txheej yog qhov tseem ceeb rau kev ntseeg siab thiab kev ua haujlwm ntawm cov twj. Kev khiav hauj lwm hauv cheeb tsam kam rau ntawm ob sab ntawm qhov zoo tshaj plaws efficiency point (BEP) ntawm lub twj tso kua mis tuaj yeem ua rau nws muaj peev xwm tiv taus qhov yuam kev. Nyob deb ntawm qhov chaw no tuaj yeem ua rau muaj kev vibration ntxiv, lub neej luv luv, lub neej ua haujlwm luv luv, kev ua haujlwm tsis zoo, thiab tag nrho cov twj tso kua mis luv lub neej.
2. Ua raws li qhov yuav tsum tau hloov tas li
Ib qho xwm txheej tshwm sim yog tias lub twj tso kua mis tau siv ntau xyoo, tab sis lub sijhawm no, qhov xwm txheej ntawm daim ntawv thov tau hloov pauv. Piv txwv li, tus nqi ntws feem ntau yog txo los ntawm kev siv lub valve downstream ntawm lub twj tso kua mis. Qhov no txhais tau hais tias lub twj tso kua mis tuaj yeem ua haujlwm tsawg dua 50% ntawm nws tus qauv tsim tus nqi, uas ua rau cov nqi khiav lag luam nce ntxiv thiab cuam tshuam rau kev pabcuam lub neej ntawm kev tswj valve. Txawm li cas los xij, kev poob hauv kev ua haujlwm twj tso kua mis mus unnoticed; Tus neeg teb xov tooj tuaj yeem qhib qhov tswj valve me ntsis rau kev them nyiaj.
Qhov kev daws teeb meem yog los kho cov hydraulic tsis ntawm lub twj tso kua mis kom zoo dua qhov kev hloov kho daim ntawv thov. Qhov no tso cai rau lub valve tswj tau siv rau nws lub hom phiaj, es tsis yog raws li qhov txwv tsis pub khiav, thiab lub twj tso kua mis tuaj yeem ua haujlwm ze nws BEP. Txawm li cas los xij, kev hloov pauv ib zaug (xws li trimming lub impeller) tuaj yeem ua tiav qhov kev xav tau, tab sis nws kuj tseem tuaj yeem coj lwm yam teeb meem, yog li xav tau kev tshuaj xyuas kom zoo.
3. Xyuas kom tus nqi ntws tsawg kawg nkaus
Lwm qhov teeb meem tshwm sim yog tsom ib ncig ntawm lub kaw lus kom tswj tau qhov tsawg kawg nkaus tus nqi ntawm lub twj tso kua mis inlet. Circulating li qub yog siv los xyuas kom meej qhov tsawg kawg nkaus ruaj khov ntws los tiv thaiv lub twj tso kua mis los ntawm kev puas tsuaj tsawg, tab sis tag nrho cov dej ntws los ntawm cov li qub no sib npaug rau cov khib nyiab. Dab tsi ua rau qhov teeb meem no nyuaj dua yog tias cov tshuab no feem ntau teeb tsa tsis raug, thiab dhau sijhawm, qhov teeb meem me me no tuaj yeem muaj qhov tshwm sim tseem ceeb, xws li cavitation puas rau lub impeller.
Tus neeg teb xov tooj tuaj yeem hloov lub voj voog ncig, tab sis tsis muaj kev paub lossis kev muaj peev xwm los xyuas kom meej kev teeb tsa thiab teeb tsa. Txij thaum ntawd los, cov twj tso kua mis uas yuav tsum tau tiv thaiv yuav muaj kev nrawm nrawm thiab tsim kua muag.
4. Cov khoom tshiab
Obviously, tom qab siv ntau xyoo, cov twj tso kua mis yuav hnav thiab thaum kawg yuav tsum tau hloov. Lub sijhawm no, nws yog ib qho tseem ceeb kom nkag siab qhov sib txawv ntawm cov khoom siv rov ua dua tshiab thiab cov khoom siv rov ua dua tshiab, nrog rau kev nce qib hauv cov ntaub ntawv, kev tshuaj xyuas tsim, thiab cov txheej txheem tsim khoom ua rau cov khoom tshiab los muab kev ua tau zoo dua thiab kev ntseeg tau.
Tsuas yog rov tsim cov khoom uas twb muaj lawm tuaj yeem ua rau txo qis kev ua haujlwm, tsis ua haujlwm ntxov ntxov ntawm cov kabmob thiab cov ntsaws ruaj ruaj, thiab nce kev vibration. Yog vim li cas rau cov teeb meem no tej zaum yuav tsis muaj kev tsim engineering txhais tau tias, uas txhais tau hais tias qhov tshiab qhov ntev tsis tuaj yeem ua tiav, qhov smoothness ntawm qhov chaw qis dua tus qauv, thiab qhov khoob tsis zoo tagnrho.
Los ntawm kev siv cov khoom qub los ua qhov chaw pib thiab siv cov qauv kev tsim vaj tsev tam sim no los txhim kho qhov tsim, cov khoom tshiab nrog cov qauv hydraulic zoo tshaj plaws tuaj yeem tsim. Kev hloov kho me me kuj tseem tuaj yeem ua kom cov kabmob zoo dua qub thiab kev foob tsim ib feem ntawm txoj haujlwm, yog li txuas ntxiv kev pabcuam lub neej thiab txo cov nqi kho.
5. Cov kabmob
Kev tsim cov twj ntsug tso siab rau kev tsim qauv zoo kom ua tiav kev ua tau zoo. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nkag siab tag nrho cov kev xaiv rau cov khoom siv thiab lubrication tshuab los xyuas kom meej lub installation ntawm qhov tsim nyog tshaj plaws. Los ntawm kev sib piv cov kabmob tsim nrog daim ntawv thov, kev pabcuam lub neej ntawm lub twj tso kua mis tuaj yeem txuas ntxiv thiab cov nqi kho yuav raug txo kom tsawg.
Feem ntau, kev hnav ntawm cov kabmob hauv lub cev txiav txim siab txog kev saib xyuas ntawm lub twj tso kua mis, yog li cov kev xaiv tau ua nyob rau lub sijhawm no yuav muaj kev cuam tshuam loj rau yav tom ntej. Kev siv cov ntaub ntawv sib xyaw pab tiv thaiv kom qhuav khiav thiab muab kev hnav zoo dua thiab tiv thaiv corrosion.
Txhua daim ntawv thov muaj qhov zoo tshaj plaws bearing tsim, nrog rau lubrication technology siv. Qee zaum, nws yog qhov tsim nyog los siv cov kabmob raj plhaub, thaum lwm qhov, kev ua haujlwm ntawm lubricating cov kabmob nrog cov khoom zoo dua. Nws yog ib qho tseem ceeb kom nkag siab txog qhov zoo ntawm txhua qhov system thiab koom tes nrog cov kws tshaj lij tsim cov twj tso kua mis los muab cov lus pom zoo ntawm cov txheej txheem tsim nyog tshaj plaws.
6. Sealing system
Thaum ua hauj lwm nrog bearings, lub sealing system kuj yuav tsum tau xav txog. Txawm hais tias kev ntim khoom ib txwm yog tus qauv tsim yav dhau los, nws tseem tuav ib qho chaw hauv cov tshuab sealing niaj hnub. Yog tias khaws cia kom zoo, nws tuaj yeem ntxiv cov bearings, muab kev txhawb nqa ntxiv, thiab pab txo qis kev vibrations.
Lub caij no, nyob ntawm daim ntawv thov, mechanical seals kuj muaj lawv qhov chaw.
Kev txhim kho lub twj tso kua mis kom raug tom qab ua tiav qhov kev saib xyuas yog qhov tseem ceeb rau kev ruaj ntseg ruaj khov. Kev sib raug zoo ntawm lub twj tso kua mis ntsug yog ib qho tseem ceeb tshaj plaws hauv txhua txoj kev tu. Qhov no siv rau lub hauv paus phaj thiab nruab nrab bearings. Cov txheej txheem sib dhos thiab kev teeb tsa yuav tsum ua kom zoo zoo, txwv tsis pub qhov sib txawv me ntsis raws li qhov ntev ntawm lub twj tso kua mis tuaj yeem tshwm sim, uas tuaj yeem ua rau lub neej luv luv.
