Khoom Description
Rau lub chaw khiav dej num ISO 2858, tus nqi tiag tiag tsis nyob ntawm daim ntawv teev npe-nws nyob hauv Rov Qab Pull-Tom ntej tsim. Yog tias koj lub IS series tau teeb tsa nrog lub qhov sib txuas sib txuas, kev saib xyuas yog ib qho - txiv neej txoj haujlwm: koj tshem lub thav duab thiab xaub tag nrho cov khoom sib dhos tawm. Lub casing thiab cov kav dej nyob twj ywm bolted rau hauv pem teb. Tsis muaj realignment, tsis muaj kev cuam tshuam manifold.
Rotor & Axial Thrust Logic
Lub plawv ntawm IS lub twj tso kua mis yog qhov sib npaug rotor. Peb laum qhov sib npaug rau hauv qab npog phaj ntawm lub impeller kom sib npaug ntawm qhov siab. Yog tias koj cov txheej txheem cov kua dej yog qhov ua rau scaling lossis crystallization, ua tib zoo saib ntawm cov qhov no. Yog tias lawv txhaws, qhov axial thrust yuav skyrocket, thiab koj yuav tau hloov cov kabmob thrust bearings txhua lub hlis es tsis txhob ntawm txhua xyoo. Ntawm cov thav ntawv me me uas lub zog qis, peb cia siab rau hnyav- lub luag haujlwm pob bearings los ntaus, tab sis rau cov qauv loj 200mm+, qhov sib npaug ntawm qhov sib npaug / foob lub nplhaib combo yog koj thawj qhov kev tiv thaiv ntawm ncej deflection.
Sealing the Shaft: Stuffing Box vs Mech Seal
Soft Packing (Lub Gland): Qhov no tseem yog tus qauv rau cov chaw nyob deb. Tus yuam sij yog Lub Nplhaib Teeb (Packing Ring). Thaum koj rub los ntawm lub tshuab nqus tsev los yog qhov tob tob, huab cua xav nkag mus rau hauv cov ncej. Peb hloov cov kwj dej me me ntawm cov dej ntws tawm sab nraud rov qab mus rau hauv lub thawv ntim khoom ntawm qhov chaw nres nkoj sab hauv hauv lub twj tso kua mis. Qhov no tsim cov kua nplaum.
Txoj Cai Leakage: Yog tias cov ntim tsis poob (30-50 tee / min), nws hlawv. Cov ntim ntim qhuav yuav "lub duav" koj lub tes tsho hauv ib qho ua haujlwm.
Lub Tes Tsho Tiv Thaiv: Peb siv lub tes tsho txiab txiab. Thaum nws hnav, koj hloov lub tes tsho, tsis yog tus ncej kim.
Mechanical Seals (DIN 24960): Rau xoom- qhov yuav tsum tau ua kom tawg, peb haum ib qho - ntsej muag, tsis yog - sib npaug foob.
Qhov "S" Dimension: Thaum hloov lub foob, tsis txhob thawb nws hauv. Yog tias koj lub foob hloov tau ntev me ntsis, koj yuav tsum tau txiav lub tes tsho luv luv lossis rov qab tawm ntawm lub nplhaib tuav kom ntaus qhov chaw qab zib ntawm lub caij nplooj ntoo hlav.
ISR Configuration: Kov Kub (80℃- 130 degree)
Tus qauv IS lub twj tso kua mis yog lub tshuab 80 degree. Yog tias koj thawb 100℃+ dej kub, koj xav tau ISR variant. Nws ntxiv ib chav txias ntawm lub taub hau twj tso kua mis thiab cov kabmob vaj tse. Koj yuav pom ob lub 1/2 "chaw nres nkoj ntawm lub hau- cov yeeb nkab dej txias los ntawm qhov ntawd kom lub sealing cheeb tsam txias. Yog tias koj tsis ua li ntawd, lub tshav kub yuav ua rau cov roj lubricating ua rau "qhuav" tsis ua hauj lwm ntev ua ntej lub foob yuav tawm.
Installation "Gotchas"
Kev taw qhia ntawm kev sib hloov: Tsis txhob sim lub cav tig thaum lub twj tso kua mis ua ke thiab khoob. Yog hais tias nws tig rov qab, lub impeller txiv ntoo tuaj yeem tig tawm, muaj peev xwm tawg lub casing lossis lub impeller vanes.
Yeeb Nkab Kev Nyuaj Siab: Yog tias koj xav tau lub crowbar kom tau koj lub flange bolts rau hauv, koj lub twj tso kua mis yuav poob. Lub twj tso kua mis yog lub nkoj hydraulic, tsis yog cov yeeb nkab txhawb nqa. Siv cov hangers ywj siab rau koj cov kab nqus / tso tawm.
Lub 3-Minute Deadhead: Tsis txhob khiav lub twj tso kua mis no tiv thaiv lub valve kaw rau ntau tshaj 3 feeb. Cov dej yuav boil, lub tshuab foob yuav tawg los ntawm thermal shock, thiab lub impeller yuav txeeb tau.
Daim ntawv teev kev ua haujlwm
Bearing Temp: 40℃saum ambient yog qhov qub. Yog hais tias nws hits 80 degree, koj twb dhau -greased nws los yog koj alignment yog tawm ntawm whack.
Priming: IS cov twj tsis yog tus kheej -priming. Yog tias koj tsis sau cov kab nqus dej thiab tso cua (ntawm lub ntsaws sab saum toj), koj yuav muaj xoom txaus thiab lub foob puas.
Hnav Ring Gap: Thaum koj ntws pib poob, nws feem ntau yog lub nplhaib hnav. Lub twj tso kua mis tshiab muaj qhov sib txawv ntawm 0.15mm - 0.25mm radial. Thaum qhov ntawd doubles, koj efficiency mus rau hauv lub bin.
