Multi-theem Barrel Casing Pump (API610 BB5)
Khoom nta
1. Lub tog raj kheej: Raws li qhov flange siab theem, lub tog raj kheej muaj ob lub qauv: casting lossis forging; lub centerline txhawb nqa lub tog raj kheej tuaj yeem txhim kho thermal stability thiab tiv taus siab dua nozzle load.
2. Core pob: Cov pob tseem ceeb (cov lus qhia vane, impeller sib dhos, ncej, twj tso kua mis, lub thawv bearing, thiab lwm yam) txais yuav ib qho kev tshem tawm tag nrho, uas ua rau kev tshuaj xyuas thiab kev saib xyuas ntawm lub twj tso kua mis tsis txav cov kav dej thiab qhov hluav taws xob.
3. Impeller thiab qhia vane: Lub impeller thiab qhia vane yog precision nrum. Tus qauv impeller thiab ncej yog plam-mounted thiab tsau ib kauj ruam hauv ib nrab-ntiv nplhaib. Rau cov dej num hnyav ua haujlwm, lub impeller yog qhov cuam tshuam haum, thiab ib kauj ruam yog siv rau txhua theem ntawm impeller. Cov qauv ncej txhawb kev txhim kho thiab kho; DN80 (qhov hluav taws xob) thiab cov lus qhia saum toj no tuaj yeem nruab nrog thawj theem ob-suction impeller los txhim kho cavitation tsis kam NPSH.
4. Axial quab yuam sib npaug: Cov impellers tau npaj ua ke thiab siv lub nruas sib npaug kom sib npaug ntawm axial quab yuam, thiab cov seem axial quab yuam yog yug los ntawm cov kabmob thrust; cov impellers yog teem rau rov qab symmetrically rau nws tus kheej sib npaug lub axial quab yuam, thiab lub nruab nrab bushing thiab caj pas bushing sib npaug ntawm seem seem quab yuam, lub thrust bearing tsuas bears qis loads.
5. Bearings thiab lubrication: Cov bearings siv roj nplhaib self-lubricating qauv bearings los yog yuam lubrication qauv bearings raws li lub zog ncej thiab ceev. Tag nrho cov koob tau txais cov kabmob cais hom ntsaws ruaj ruaj, thiab cov pa roj carbon steel bearing lub thawv tau txais kev txhawb nqa ntawm 360 °. Lub thawv bearing tuaj yeem ua rau cua txias lossis dej txias muaj.
6. Lub foob foob: Lub kaw lus sealing siv 4th tsab ntawm API682 "Centrifugal Pump thiab Rotary Pump Sealing System" thiab tuaj yeem teeb tsa nrog ntau hom kev sib khi, yaug, thiab cov kev daws teeb meem txias.
