1. Tus tshiab zoo dua tus qub
Hais txog hais lus, kev siv cov tshuab ntsaws ruaj ruaj tshiab rau ntsug kav dej centrifugal twj tso kua mis zoo dua qub. Txawm li cas los xij, yog tias qhov zoo lossis cov khoom xaiv ntawm lub tshuab foob tshiab tsis tsim nyog thiab muaj qhov yuam kev loj dua, nws yuav cuam tshuam rau kev sib khi; Hauv cov xov xwm polymeric thiab permeable, nws yog qhov zoo dua tsis hloov lub nplhaib zoo li qub yog tias tsis hnav ntau dhau. Vim hais tias lub nplhaib ruaj ruaj nyob rau hauv ib qho chaw ruaj khov rau lub sijhawm ntev hauv lub nplhaib ruaj ruaj, cov khoom siv polymer thiab impurities tso ua ke, muab cov nyhuv sealing zoo.
2. Dismantling thiab kho yog zoo dua tsis dismantling txhua
Thaum muaj ib qho kev sib tsoo ntawm lub tshuab foob tau tshwm sim, nws tseem ceeb heev rau kev rhuav tshem thiab kho nws. Qhov tseeb, qee zaum lub foob tsis raug puas tsuaj, thiab tsuas yog kho cov haujlwm ua haujlwm lossis kho kom zoo ntawm lub foob tuaj yeem tshem tawm cov xau. Qhov no tsis yog tsuas yog zam cov khib nyiab xwb tab sis kuj txheeb xyuas qhov muaj peev xwm kuaj xyuas qhov yuam kev, khaws cov kev paub txog kev saib xyuas, thiab txhim kho qhov zoo ntawm kev saib xyuas.
3. Qhov ntau dua qhov compression ntawm lub caij nplooj ntoos hlav, qhov zoo ntawm sealing nyhuv
Nyob rau hauv qhov tseeb, ntau compression ntawm lub caij nplooj ntoos hlav nyob rau hauv ib tug ntsug pipeline centrifugal twj tso kua mis tuaj yeem ua rau hnav sai sai thiab kub hnyiab ntawm kev sib txhuam khub; Compression ntau dhau ua rau lub caij nplooj ntoos hlav poob nws lub peev xwm los kho lub ntsej muag kawg ntawm lub nplhaib txav, ua rau lub foob tsis ua haujlwm.
4. Qhov nruj dua qhov dynamic nplhaib foob daim duab, qhov zoo dua
Qhov tseeb, zawm lub nplhaib dynamic foob yog teeb meem thiab tsis muaj txiaj ntsig. Ua ntej, nws exacerbates hnav ntawm lub nplhaib sealing thiab lub tes tsho ncej, ua rau kom ntxov ntxov; Qhov thib ob, nws ua rau kom muaj kev tiv thaiv axial hloov thiab txav ntawm lub nplhaib txav, ua rau nws nyuaj rau kev hloov kho raws sijhawm thaum ua haujlwm hloov ntau zaus; Thib peb, lub caij nplooj ntoos hlav yog qhov ua rau muaj kev puas tsuaj vim kev qaug zog ntau dhau; Qhov thib plaub yog deform lub nplhaib sealing ntawm lub nplhaib txav, uas cuam tshuam rau cov nyhuv sealing.
5. Qhov nruj dua lub nplhaib zoo li qub, qhov zoo dua
Lub nplhaib zoo li qub yog qhov tseem ceeb hauv lub xeev zoo li qub, thiab lub foob kaw ntom ntom yuav muaj kev sib khi zoo dua, tab sis nruj dhau kuj ua rau muaj kev phom sij. Ib qho yog ua rau ntau dhau deformation ntawm lub nplhaib zoo li qub, uas cuam tshuam rau cov nyhuv sealing; Qhov thib ob yog vim li cas cov khoom ntawm lub nplhaib zoo li qub feem ntau yog graphite, uas feem ntau yog nkig thiab ua rau tawg nyob rau hauv kev ntxhov siab ntau dhau; Thirdly, installation thiab disassembly yog qhov nyuaj, thiab lub nplhaib zoo li qub tau yooj yim puas.
6. Lub impeller xauv cov txiv ntseej, qhov zoo dua
Nyob rau hauv mechanical seal to, leakage ntawm lub tes tsho ncej thiab lub ncej (inter shaft to leakage) yog heev. Nws yog feem ntau ntseeg hais tias inter shaft leakage yog tshwm sim los ntawm impeller locking txiv ntseej tsis raug nruj. Qhov tseeb, muaj ntau yam uas tuaj yeem ua rau muaj qhov sib txawv ntawm lub tog raj kheej, xws li qhov tsis ua hauj lwm thiab kev hloov pauv ntawm qhov sib txuas ntawm lub tog raj kheej, cov impurities nyob rau hauv cov ncej, qhov tseem ceeb ntawm qhov chaw tsis raug ntawm qhov haum ntawm lub ncej thiab lub tes tsho, kev puas tsuaj rau qhov chaw sib chwv, qhov khoob ntawm ntau yam ntawm cov ncej, thiab cov ntsia hlau ntev ntev tuaj yeem ua rau lub taub hau sib txuas.
Excessive locking of the locking nut of a vertical pipeline centrifugal pump will only lead to premature failure of the shaft gasket. Ntawm qhov tsis sib xws, qhov nruab nrab ntawm qhov ntsuas phoo ntawm cov txiv ntoo xauv tuaj yeem tswj tau qee qhov ntawm compression elasticity ntawm cov ncej gasket. Thaum lub sijhawm ua haujlwm, lub ntsuas phoo yuav tau txais thiab lub sijhawm kaw, kom ntseeg tau tias lub tog raj kheej yog ib txwm nyob rau hauv lub xeev sealing zoo.
