Ib/ob theem radical cais twj tso kua mis (API610/BB2)

1. Lub cev twj tso kua mis: Lub twj tso kua mis lub cev siv ob chav scroll chamber qauv los txo cov radial quab yuam, txo cov ncej load, thiab ncua lub neej kev pab cuam ntawm cov bearings; centerline installation thiab kev txhawb nqa cov qauv ntawm ob qho kawg tuaj yeem txhim kho kev ua haujlwm ntawm lub twj tso kua mis vim qhov kub thiab txias hauv qhov kub thiab txias. Qhov siab yuav ua rau nthuav dav thiab deformation ntawm lub twj tso kua mis lub cev; lub qhov hluav taws xob thiab qhov hluav taws xob ntawm lub twj tso kua mis lub cev tuaj yeem teeb tsa hauv ntau cov lus qhia kom yooj yim rau tus neeg siv lub raj xa dej;

2. Pump cover: Lub twj tso kua mis cover muaj ib tug nruj tsim, muaj zog-bearing muaj peev xwm, thiab muaj kev ntseeg siab. Ib qho kev txhim khu kev qha hlau winding gasket yog siv los kaw lub twj tso kua mis lub cev thiab lub twj tso kua mis npog, ua kom yooj yim rau kev thauj mus los ntawm qhov kub thiab txias, tshuaj lom neeg, tsim kev puas tsuaj, thiab yooj yim vaporized media;

3. Impeller: Cov qauv ib-theem feem ntau siv ob-suction impeller kom txo cov NPSH ntawm lub twj tso kua mis thiab txo tus nqi ntawm cov khoom siv. Nyob rau tib lub sijhawm, ob-suction impeller tuaj yeem sib npaug ntawm axial quab yuam tsim los ntawm nws tus kheej: ob-theem qauv feem ntau siv thawj-theem ob-suction thiab thib ob-theem impeller. Thawj-theem ib leeg-suction qauv thiab thawj-theem ob chav suction tuaj yeem coj mus rau hauv tus account qhov xav tau cavitation ntawm lub twj tso kua mis. Qhov thib ob impeller siv qhov sib npaug ntawm qhov sib npaug ntawm axial siab, thiab qhov seem axial quab yuam yog los ntawm cov kabmob. Rau kev ua haujlwm nrog cov kev xav tau qis ntawm kev ua haujlwm cavitation thiab kev ua haujlwm siab, ob-theem ib leeg-suction rov qab-rau-rov qab lossis lub ntsej muag-rau-lub ntsej muag qauv tuaj yeem txiav txim siab;

4. Ncej: Nws txais kev tsim ncej nruj nrog me me deflection. Yog hais tias tus ncej txoj kab uas hla yog ntau tshaj 60 hli, nws yog tsim raws li ib tug conical ncej txuas ntxiv, uas yooj yim rau installation thiab disassembly ntawm couplings, bearings thiab seals;

5. Bearings thiab lubrication: Cov bearings siv roj-ntiv nplhaib self-lubricating dov bearings los yog zawv zawg bearing qauv raws li lub zog ncej thiab ceev. Thaum xaiv cov kabmob dov, qhov kawg tsav tsheb siv lub pob sib sib zog nqus los muab kev txhawb nqa radial, thiab qhov kawg uas tsis tau tsav yog nruab nrog ib khub ntawm lub kaum sab xis ntawm lub pob bearings txhawm rau txwv lub axial txav ntawm lub rotor thiab ib txhij muab radial. kev txhawb nqa; Thaum siv cov kabmob zawv zawg, cov kabmob zawv zawg radial ntawm ob qho kawg ua lub luag haujlwm txhawb nqa radial, thiab ib khub ntawm angular hu rau pob bearings yog teem rau tom qab cov kabmob radial ntawm qhov tsis tsav tsheb kawg kom txwv lub axial txav ntawm lub rotor;

6. Mechanical seal: Lub sealing system ua raws li qhov yuav tsum tau ua ntawm API682 4th Edition "Centrifugal Pump thiab Rotary Pump Sealing System" thiab Sinopec cov qauv kev yuav khoom, thiab tuaj yeem teeb tsa nrog ntau hom kev sib khi, dej ntws, thiab kev daws teeb meem txias.
