Petrochemical txheej txheem twj tso kua mis (API610 / OH1)

OH1 series centrifugal twj tso kua mis yog kab rov tav, ib-theem, radially split cantilever twj siv nyob rau hauv cov txheej txheem petrochemical. Txhawm rau txhawb nqa txhua lub zog siv rau lub twj tso kua mis thiab tuav lub rotor txoj hauj lwm, hom twj tso kua mis no muaj lub thawv cais. Kev sib txuas yooj yim txuas lub twj tso kua mis tus tsav tsheb mus rau nws lub hauv paus uas nws tau muab tso rau.

1. Lub cev twj tso kua mis: Lub zog radial yog qhov sib npaug zoo heev los ntawm ob lub volute hydraulic tsim ntawm lub twj tso kua mis lub cev tso zis (≥DN80), uas siv cov qauv tsim qauv;

2. Cov khoom raug tshem tawm (cov kabmob lub thawv, cov kabmob, cov ncej, caj pas, lub twj tso kua mis, thiab lwm yam) tau txais kev tsim qauv rub 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. Ncej: Cov ncej yog cov qauv ntawm cov ncej liab qab, thiab qhov ntsuas qhov tawv ntawm lub twj tso kua mis ua tau raws li qhov yuav tsum tau ua ntawm API61011 "Appendix K." Nyob rau tib lub sijhawm, lub impeller txiv ntoo los tiv thaiv kev thim rov qab yog siv los ua kom tau raws li qhov xav tau ntawm kev ua haujlwm ntawm qhov chaw thiab txhim kho kev nyab xeeb thiab ruaj khov ntawm cov khoom siv.

4. Axial force balancing: Lub thrust bearing tsuas yog nqa ib qho me me vim tias hnav-tiv nplhaib yog tsim rau ob sab ntawm lub impeller thiab qhov sib npaug sab hauv yog tsim los ua kom lub siab ntawm ob sab ntawm lub impeller tus kheej sib npaug;

5. Lubrication thiab bearings: Sib sib zog nqus groove pob bearings, uas tsuas yog txhawb radial quab yuam, yog siv nyob rau hauv pem hauv ntej bearing, uas yog cov bearing ze tshaj lub taub hau twj tso kua mis. Ib khub ntawm tapered roller bearings (31 series) lossis angular contact ball bearings (73 series) yog siv nyob rau hauv cov kabmob nram qab, uas yog cov kabmob ze tshaj plaws rau qhov kawg tsav. Ob hom kabmob muaj lub nplhaib roj lubrication qauv, thiab tus neeg siv tuaj yeem xaiv cov kabmob cais hom foob. Lub foob ntawm lub labyrinth;

6. Mechanical foob; Cov kab noj hniav loj ua raws li API682 4th "Centrifugal Pump thiab Rotary Pump Shaft Seal System", thiab ntau hom kev sib khi, dej ntws, thiab cov kev daws teeb meem txias tuaj yeem teeb tsa.

Ntxuav los yog qias neeg, tsis tshua muaj kub los yog kub, chemically nruab nrab los yog corrosive kua, petrochemical, chemical kev lag luam, thee chemical, refinery, pulp thiab ntawv, koog tsev kawm ntawv cua sov, flue gas desulfurization thiab dav siv nyob rau hauv industrial siv.
