Tus ncej Overhaul ntawm Split Case Pump
Cov ncej ntawm lub cais case lub twj tso kua mis yog ib qho tseem ceeb heev, thiab lub impeller tig ntawm kev kub ceev los ntawm lub cev muaj zog thiab kev sib txuas. Cov kua nruab nrab ntawm cov hniav yog thawb los ntawm cov hniav, thiab tsis tu ncua pov los ntawm sab hauv mus rau qhov chaw nyob rau hauv qhov kev txiav txim ntawm lub centrifugal quab yuam. Ib cheeb tsam uas tsis tshua muaj siab yog tsim thaum cov kua hauv lub twj tso kua mis pov tseg los ntawm lub impeller mus rau ntug. Vim tias lub siab ntawm cov kua ua ntej nkag mus rau hauv lub twj tso kua mis ntau dua qhov siab ntawm qhov chaw nqus ntawm lub twj tso kua mis, txoj hauj lwm qhov sib txawv ntawm qhov siab yog tawm ntawm cov kua, qhov sib cais. cas twj yuav tsum tau npaj tsis tu ncua raws li kev tswj hwm kev paub dhau los thiab cov khoom siv ntawm cov cuab yeej tsim khoom, thiab kev saib xyuas yuav tsum tau ua raws li txoj kev npaj.
1. Ra = 1.6um ntawm qhov chaw ntawm lub bushing.
2. Cov ncej thiab bushing yog H7 / h6.
3. Lub npoo npoo yog du, tsis muaj kab nrib pleb, hnav, thiab lwm yam.
4. Qhov kev ua yuam kev sib luag ntawm qhov nruab nrab ntawm qhov tseem ceeb ntawm lub twj tso kua mis centrifugal thiab qhov nruab nrab ntawm cov ncej yuav tsum tsawg dua 0.03 hli.
5. Qhov kev tso cai khoov ntawm lub taub hau tsis ntau tshaj 0.013mm, qhov nruab nrab ntawm lub twj tso kua mis qis qis tsis tshaj 0.07mm, thiab qhov nruab nrab ntawm lub twj tso kua mis ceev tsis tshaj 0.04mm. .
6. Ntxuav thiab xyuas lub twj tso kua mis ncej ntawm ob-suction nruab nrab-qhib twj tso kua mis. Lub twj tso kua mis yuav tsum tsis muaj qhov tsis xws luag xws li tawg thiab hnav hnyav. Muaj hnav, tawg, yaig, thiab lwm yam, uas yuav tsum tau sau kom meej, thiab cov laj thawj yuav tsum tau soj ntsuam.
7. Qhov ncaj ntawm lub taub hau ntawm lub twj tso kua mis centrifugal yuav tsum tsis pub tshaj 0.05 hli rau tag nrho qhov ntev. Cov ntawv xov xwm saum npoo yuav tsum tsis pub muaj pits, grooves thiab lwm yam tsis xws luag. Tus nqi ntawm qhov roughness ntawm qhov chaw yog 0.8μm, thiab lub roundness thiab cylindricity yuam kev ntawm phau ntawv journal yuav tsum tsawg tshaj li 0.02mm.
