Kev Paub: Kho ntawmSplit Case twj tso kua mis Corrosion thiab Erosion puas

Rau qee qhov kev siv, kev txhim kho corrosion thiab / lossis kev puas tsuaj tsis tuaj yeem zam tau. Thaum twgcais casecov twj tso kua mis tau txais kev kho thiab raug puas tsuaj, lawv yuav zoo li cov hlau seem, tab sis nrog cov txheej txheem kho kom zoo, feem ntau lawv tuaj yeem rov qab los rau lawv qhov kev ua tau zoo qub lossis zoo dua. Kev puas tsuaj los ntawm kev xeb thiab / lossis kev yaig tuaj yeem tshwm sim ntawm cov twj tso kua mis twj tso kua mis nrog rau cov rotating impellers.

CEEB TOOM: Kev puas tsuaj cavitation yog ib hom kev puas tsuaj.

1. Txheej Kho

Kev kho cov txheej txheem rau cov hlau puas raug muab faib ua peb pawg: txheej txheej kho, kho tshuab thiab kho vuam. Ntawm chav kawm, ntau yam kev kho mob suav nrog kev sib xyaw ntawm tag nrho peb. Ntawm peb txoj kev, txheej txheej kho yog qhov yooj yim tshaj plaws thiab feem ntau yog qhov yooj yim rau kev siv. Muaj ntau tus neeg muag khoom thiab ntau yam khoom siv kho dua tshiab tsim tshwj xeeb rau lub hom phiaj no.

2. Mkho echanical

Machining kho yog feem ntau thaum lub seam nto ntawm split case twj tso kua mis cov khoom puas lawm. Txij li thaum kev sib xyaw ua ke ntawm cov twj tso kua mis tuaj yeem cuam tshuam los ntawm cov seam tiav, kev tsim tsim nyog yuav tsum tau ua kom lub twj tso kua mis rov qab ua ke kom zoo. Tau kawg, kev tswj xyuas qhov concentricity thiab perpendicularity ntawm qhov chaw yog qhov tseem ceeb. Tsis tas li ntawd, thaum lub ntsej muag spigot yog machined los tshem tawm kev puas tsuaj, nws hloov lub axial txoj hauj lwm ntawm mating thiab lwm yam khoom.

Yog hais tias lub axial txoj hauj lwm ntawm bearings, cov ntsaws ruaj ruaj, hnav rings los yog lwm yam precision qhov chaw raug cuam tshuam, nws yuav tsum tau kho txoj hauj lwm ntawm cov khoom, xws li kho txoj hauj lwm ntawm lub xub pwg nyom ntawm qhov chaw bearings ntawm lub ncej. Yog hais tias tus impeller ntawm lub ntsug turbine twj tso kua mis yog nruab nrog lub nplhaib ncej qhov tseem ceeb, machining lub seam lub ntsej muag ntawm lub taag ib feem yuav tsum tau machining ib tug tshiab ncej nrog ib tug kho lub nplhaib tseem ceeb txoj hauj lwm.

3. Weldhauv Repair

Kev kho vuam yog qhov tsawg kawg nkaus uas xav tau. Cam khwb cia twj tso kua mis Cheebtsam ( impellers thiab chaw nres tsheb qhov chaw ) yuav nyuaj rau kho los ntawm vuam. Brazing tuaj yeem ua tiav, tab sis cov khoom yuav tsum tau muab cua sov sib npaug, thiab txawm tias qhov no tuaj yeem ua rau muaj kev cuam tshuam. Kev kho weld dav rau cov khoom siv yuav xav tau rov ua haujlwm ntawm txhua qhov chaw ua haujlwm kom ntseeg tau tias qhov cuam tshuam ntawm kev cuam tshuam raug tshem tawm.

Ib qho piv txwv yog kev kho ntawm mating nto ntawm kev sib caiscov ntaub ntawvcov twj tso kua mis siv hauv cov tshuab dej sib xyaw. Yog hais tias lub mating twj tso kua mis nyob rau saum npoo yog puas, ob peb txhiab (microns) yuav raug machined tawm kom tau ib tug tshiab tiaj tus nto. Txhawm rau kom ua tiav qhov haum zoo tom qab machining, lub twj tso kua mis tuab tuaj yeem ua kom haum rau cov khoom siv tshem tawm. Txawm li cas los xij, qhov no tsis haum rau kev saib xyuas cov twj siv hluav taws xob siab. Kev kho ntawm cov twj siv hluav taws xob siab no yog dhau ntawm cov kab lus no.

Kev kho corrosion thiab / lossis kev puas tsuaj uas tshwm sim hauv ntau lub twj tso kua mis yog qhov tseem ceeb ntawm kev kho lub twj tso kua mis. Yog tias qhov chaw puas lawm sab laug tsis kho, cov txheej txheem kev puas tsuaj yuav nrawm dua vim muaj kev kub ntxhov ntau dhau ntawm qhov ntxhib saum npoo. Txoj kev piav qhia ntawm no yuav tsum pab daws cov teeb meem kev noj nyiaj txiag feem ntau.
