Dab tsi yog vim li cas rau qhov txo qhov hluav taws xob siab ntawm cov twj centrifugal? Ib lossis ntau qhov laj thawj hauv qab no tuaj yeem ua rau txo qis qhov hluav taws xob ntawm lub twj tso kua mis centrifugal:
(1) Lub cev muaj zog thim rov qab
Vim yog vim li cas txuas, kev taw qhia ntawm lub cev muaj zog tuaj yeem yog qhov sib txawv ntawm qhov xav tau tiag tiag ntawm lub twj tso kua mis. Yog li ntawd, thaum pib, nws yog feem ntau yuav tsum tau soj ntsuam cov kev taw qhia ntawm lub twj tso kua mis ua ntej. Yog hais tias qhov kev taw qhia yog thim rov qab, ob lub xov hlau ntawm lub tshuab hluav taws xob yuav tsum tau pauv.
(2) Deviation ntawm kev khiav hauj lwm taw tes rau siab ntws thiab qis taub hau
Feem ntau, centrifugal twj tso kua mis muaj ib tug nruam downward kev ua tau zoo nkhaus, thiab tus nqi ntws maj mam nce nrog lub taub hau txo. Thaum lub sijhawm ua haujlwm, vim qee qhov laj thawj, lub zog rov qab ntawm lub twj tso kua mis txo qis, thiab qhov chaw ua haujlwm ntawm lub twj tso kua mis passively hloov mus rau lub taub hau qis thiab siab ntws taw tes raws li cov cuab yeej nkhaus, uas yuav ua rau lub taub hau poob. Qhov tseeb, qhov no yog tshwm sim los ntawm lwm yam xws li kev hloov hauv lub cuab yeej, thiab tsis muaj dab tsi ua rau lub twj tso kua mis nws tus kheej. Ntawm no, tsuas yog nce lub twj tso kua mis rov qab, xws li kaw lub qhov hluav taws xob valve me ntsis, tuaj yeem daws qhov teeb meem.
(3) Kev txo qis
Cov yam tseem ceeb uas cuam tshuam rau lub taub hau twj tso kua mis yog lub taub sab nraud ntawm lub impeller thiab lub twj tso kua mis ceev. Hauv lwm qhov xwm txheej tas li, lub taub hau twj tso kua mis yog ncaj qha proportional rau lub zog thib ob ntawm kev ceev, qhia tias qhov ceev muaj qhov cuam tshuam loj rau lub taub hau. Qee lub sij hawm, vim yog sab nraud, lub twj tso kua mis ceev txo, uas yuav ua rau txo lub taub hau twj tso kua mis. Lub sijhawm no, lub twj tso kua mis ceev yuav tsum tau kuaj xyuas. Yog tias qhov ceev tiag tiag tsis txaus, qhov laj thawj yuav tsum tau tshawb xyuas thiab daws qhov tsim nyog.
(4) Cavitation tshwm sim ntawm qhov nkag
Yog tias qhov nqus siab ntawm lub twj tso kua mis qis dhau, qis dua qhov nqus vapor siab ntawm qhov nruab nrab, cavitation yuav tshwm sim. Nyob rau lub sijhawm no, nws yog ib qho tsim nyog los tshawb xyuas seb qhov cuab yeej siv hluav taws xob tau thaiv lossis seb qhov Inlet Valve qhib yog qhov tsawg dua, lossis nce qib dej ntawm kev nqus dej tank.
(5) Internal leakage tshwm sim
Thaum lub clearance ntawm lub rotating thiab nyob twj ywm qhov chaw nyob rau hauv lub twj tso kua mis tshaj qhov tsim ntau yam, nws yuav ua rau sab hauv to, manifested raws li ib tug txo nyob rau hauv lub tso tawm siab ntawm lub twj tso kua mis, xws li clearance ntawm lub impeller lub qhov ncauj nplhaib thiab inter-theem clearance. multi-theem twj tso kua mis. Nyob rau lub sijhawm no, kev sib xyaw ua ke thiab kev tshuaj xyuas yuav tsum tau ua los kho lossis hloov cov khoom uas ua rau muaj kev tshem tawm ntau dhau.
(6) Impeller ntws channel thaiv
Yog tias qhov ntws channel ntawm lub impeller raug thaiv, nws yuav cuam tshuam rau kev ua haujlwm ntawm lub impeller thiab ua rau txo qhov hluav taws xob siab. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum dismantle lub twj tso kua mis rau kev tshuaj xyuas thiab tshem tawm cov khoom txawv teb chaws. Txhawm rau tiv thaiv qhov teeb meem tsis tshwm sim dua, lub tshuab lim tuaj yeem ntxiv ua ntej lub twj tso kua mis yog tias tsim nyog.
Muaj ntau qhov laj thawj rau qhov txo qis hauv qhov hluav taws xob ntawm cov twj centrifugal. Thov tshawb xyuas txhua qhov laj thawj saum toj no ib los ntawm ib qho.
