Kev ua tau zoo ntawm lub twj tso kua mis centrifugal yog cov khoom siv tshuab, ntim, thiab hydraulic ua haujlwm. Lub efficiency ntawm lub twj tso kua mis yog cov khoom ntawm lub twj tso kua mis efficiency thiab lub cev muaj zog efficiency.
Ⅰ, Lub ntsiab tseem ceeb ua rau kev ua haujlwm qis ntawm centrifugal twj tso kua mis yog raws li hauv qab no.
Kev ua haujlwm ntawm lub twj tso kua mis nws tus kheej yog qhov cuam tshuam tseem ceeb. Raws li tib yam kev ua haujlwm, kev ua haujlwm ntawm cov twj tso kua mis yuav txawv ntawm ntau dua 15%.
2. Cov kev ua haujlwm ntawm cov twj tso kua mis centrifugal yog qis dua lawv cov kev ntsuas, uas ua rau lub twj tso kua mis tsis zoo thiab kev siv lub zog siab.
3. Qhov ua tau zoo ntawm lub cev muaj zog tseem tsis tau hloov pauv thaum lub sijhawm ua haujlwm. Yog li ntawd, xaiv lub siab - lub cev muaj zog yog qhov tseem ceeb.
Qhov cuam tshuam ntawm kev siv tshuab ua haujlwm feem ntau yog cuam tshuam nrog kev tsim thiab kev tsim khoom zoo. Tom qab lub twj tso kua mis raug xaiv, qhov cuam tshuam rau kev tswj xyuas tom qab yog me me.
5. Hydraulic poob muaj xws li hydraulic kev sib txhuam thiab hauv zos tsis kam. Tom qab khiav rau qee lub sijhawm, cov twj siv tshuaj inevitably ua rau saum npoo ntawm cov khoom xws li impellers thiab qhia vanes, nce hydraulic poob, thiab txo hydraulic efficiency.
6. Lub ntim poob, tseem hu ua leakage poob, ntawm cov tshuaj centrifugal twj tso kua mis muaj peb hom to losses: impeller sealing nplhaib, inter theem, thiab axial force tshuav mechanism. Qib ntawm volumetric efficiency tsis yog tsuas yog cuam tshuam rau kev tsim thiab kev tsim khoom, tab sis kuj rau kev tswj hwm kev tsim khoom. Tom qab ua haujlwm tsis tu ncua rau qee lub sijhawm, vim muaj kev sib txhuam ntawm ntau yam khoom, qhov kev tshem tawm tau nce thiab qhov ua tau zoo volumetric txo.
7. Vim yog qhov thaiv ntawm lub tog raj kheej lim, cov kav dej kom tsawg, thiab lwm yam, lub twj tso kua mis centrifugal tuaj yeem ntsib lub tshuab nqus tsev twj thiab idling.
8. Ua ntej pib lub twj tso kua mis, cov neeg ua haujlwm tsis xyuam xim rau kev npaj ua ntej pib lub twj tso kua mis centrifugal. Cov txheej txheem kev khiav hauj lwm yooj yim xws li sov- lub twj tso kua mis, lub twj tso kua mis disc, thiab lub twj tso kua mis infusion tsis ua kom tiav, uas feem ntau ua rau cavitation ntawm lub twj tso kua mis, ua rau lub twj tso kua mis muaj suab nrov, kev co, thiab lub twj tso kua mis qis.
Ⅱ, Kev ntsuas kom txo tau lub zog ntawm cov twj centrifugal thiab txhim kho twj tso kua mis
1. Tsis tu ncua tshuaj xyuas thiab kho qhov sib khi ntawm lub twj tso kua mis centrifugal kawg kom txo qhov ntim poob;
Tom qab lub twj tso kua mis centrifugal tau khiav mus rau 10000 teev, nws yuav tsum tau kho qhov loj los kho cov twj tso kua mis;
3. Txhawb nqa daim ntawv thov ntawm corrugated yeeb nkab sealing thev naus laus zis ntawm cov twj centrifugal kom tshem tawm cov pa tawm sab nraud thiab txhim kho kev ua haujlwm ntawm volumetric.
4. Tsis tu ncua ntxuav lub lim lub tog raj kheej, xyuas cov kav dej sib txuas, thiab xyuas kom meej tias cov kav dej nkag ntawm lub twj tso kua mis centrifugal tsis muaj kev cuam tshuam.
5. Ua raws li cov txheej txheem kev khiav hauj lwm rau cov tshuaj centrifugal twj. Ua ntej pib lub twj tso kua mis, lub twj tso kua mis yuav tsum tau qhib, lub inlet valve yuav tsum tau qhib, lub qhov hluav taws xob valve yuav tsum raug kaw, thiab tso pa tawm yuav tsum tau nqa tawm los xyuas seb lub inlet siab ntawm lub twj tso kua mis raws li qhov yuav tsum tau. Tiv thaiv lub twj tso kua mis cavitation tshwm sim los ntawm cov khoom siv tsis tshua muaj siab thiab tsis txaus txaus.
6. Tsis tu ncua kev ntsuas twj tso kua mis ntawm cov twj centrifugal, thiab rau cov twj tso kua mis uas tsis muaj twj tso kua mis efficiency, tam sim ntawd txheeb xyuas qhov ua rau thiab coj cov kev ntsuas los daws nws.
