Multi-theem centrifugal twj tso kua mis yog ua ke ntawm ob los yog ntau tshaj centrifugal twj nrog tib lub luag haujlwm. Nyob rau hauv cov nqe lus ntawm cov kua dej channel qauv, thawj theem qhov nruab nrab siab nyem qhov chaw nres nkoj txuas nrog rau theem thib ob lub inlet, thiab theem thib ob qhov nruab nrab siab nyem qhov chaw nres nkoj txuas nrog rau theem thib peb lub inlet. Qhov kev sib txuas ntawm cov tshuab no ua rau ntau-theem centrifugal twj tso kua mis.
Yog vim li cas rau siab poob hauv ntau-theem centrifugal twj
1. Lub cev muaj zog thim rov qab
Vim yog qhov laj thawj ntawm kev xaim, kev taw qhia ntawm lub cev muaj zog tuaj yeem cuam tshuam rau qhov kev xav tau tiag tiag ntawm lub twj tso kua mis centrifugal. 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, ntau-theem centrifugal twj tso kua mis muaj qhov kev ua haujlwm qis qis qis, thiab tus nqi ntws maj mam nce nrog qhov txo ntawm lub taub hau. Thaum lub sijhawm ua haujlwm, vim qee qhov laj thawj, qhov rov qab siab 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. Ceev txo
Cov yam tseem ceeb uas cuam tshuam rau lub taub hau ntawm ntau-theem centrifugal twj tso kua mis yog lub taub sab nraud ntawm lub impeller thiab qhov ceev ntawm lub twj tso kua mis. Hauv lwm qhov xwm txheej tas li, lub taub hau ntawm lub twj tso kua mis yog ncaj qha proportional rau lub zog thib ob ntawm qhov ceev. Nws tuaj yeem pom tias qhov cuam tshuam ntawm kev ceev ntawm lub taub hau yog qhov tseem ceeb heev. Qee zaum, vim yog sab nraud, qhov ceev ntawm lub twj tso kua mis txo qis, uas yuav ua rau txo lub taub hau ntawm lub 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 ntau-theem centrifugal twj tso kua mis qis dhau lawm, qis dua qhov nqus vapor siab ntawm qhov nruab nrab, cavitation yuav tshwm sim. At this time, it is necessary to check whether the inlet pipeline system is blocked or whether the inlet valve opening is too small, or to increase the liquid level of the suction water 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 zis siab ntawm lub twj tso kua mis, xws li clearance ntawm lub impeller lub qhov ncauj nplhaib thiab inter-theem clearance ntawm 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.
