Kev tshawb fawb txog kev tshwj xeeb thiab kev tshawb fawb engineering rau lub installation ntawm eccentric rollucers ntawm inlet ntawm centrifugal twj:

1.Txhua kev xaiv cov kev taw qhia kev teeb tsa ntawm cov khoom siv hluav taws xob ntawm eccentric ntawm cov khoom tiv thaiv cov kua hluav taws xob yuav tsum tau txiav txim siab, feem ntau ntawm cov qauv kev txiav txim siab ntau ntxiv:

Qhov tseem ceeb rau kev tiv thaiv cavitation:
Thaum lub kaw lus net zoo li lub taub hau (NPHsh) npoo tsis txaus, ib qho kev qhia ua kom paub tsis meej uas yuav tsum tau ua kom tsis txhob muaj kev tso ua kua tsis txuas ntxiv uas tuaj yeem ua rau cavitation.
Yuav Tsum Tso Kua Dej:Thaum muaj kev xav tau rau kev tsim nyog los yog pipeline yaug, ib qho kev qhia hauv qab hauv qab hauv qab tuaj yeem raug xaiv los pab txhawb qhov chaw ua kua.

2.Qhov tsom xam ntawm sab saum toj tiaj tiaj installation technology
Qhov zoo ntawm cov roj tshuab:
● Tshem tawm cov nyhuv flexitank: ua kom sab saum toj ntawm lub raj tas mus li kom tsis txhob muaj dej stratification thiab txo cov kev pheej hmoo ntawm airbag tsim-up
● Optimized Out Outt Velocity Dispitalition: Coj cov kev hloov pauv qeeb qeeb thiab txo cov kev ua rog los ntawm 20-30%
Mechanism ntawm Anti-Cavitation:
● Ua kom muaj qhov zoo siab gradient: tiv thaiv lub zog hauv zos los ntawm kev poob qis hauv qab lub vapor noo siab ntawm lub nruab nrab
Txo qhov siab siab lub paj hlwb: tshem tawm vortex tiam vortex tiam thiab txo qhov tshwm sim ntawm cavitation
Kev Pab Txhawb Thoob Ntiaj Teb:
Int Endi 610 yuav tsum muaj: Inlet Eccentric qhov chaw yuav tsum yog qhov tsis txaus siab nyob rau theem siab
Interment Tus Qauv Tsim: pom zoo rau tiaj tus mounting raws li tus qauv rau cavitation tsis kam

3.Applicable scenarios rau hauv qab-tiaj installation
Tshwj xeeb ua haujlwm:
● Cov kev tshem tawm cov txheej txheem: ua kom muaj kev tawm tsam kev tawm tsam
● Yeeb Nkab Flushing Circuit Court: Faib kev tshem tawm
Nyiaj Tsim:
● Kev tso pa tawm yuav tsum muaj
Inlet Cov kab ntsig yeeb nkab taub yuav tsum tau nce los ntawm 1-2 qib
● Nws raug nquahu kom teeb tsa cov ntsiab lus siab xyuas

4.Qhov teeb tsa cov kev taw qhia txhais cov qauv
Txhais tau siv ASME Y14.5m geometric qhov ntev thiab thev taus tus qauv:
Sab saum toj-chane constallation:Lub dav hlau ntawm cov eccentric ib feem yog yaug nrog sab hauv phab ntsa ntawm cov yeeb nkab sab saum toj
Hauv qab-tiaj installation:Lub dav hlau ntawm cov eccentric ib feem yog yaug nrog sab hauv phab ntsa hauv qab ntawm cov yeeb nkab
Nco tseg:Hauv qhov project tiag tiag, nws raug nquahu kom siv 3D laser scanning los xyuas cov teeb tsa teeb tsa.

5.suggestions rau txoj haujlwm kev siv
Cov simulation:Cavitation Allowance (NPHS) Kev Tshawb Xyuas Siv CFD Software
Cov ntawv qhia txog kev ua haujlwm ntawm thaj chaw:Cov homogeneity ntawm cov txaus spelocity faib tawm los ntawm ultrasonic yougo meter
Kev Ntsuam Xyuas Qhov Kev Kawm:Nruab siab sensors thiab kev co saib rau kev taug kev ntev
Lub Tswv Yim Txij Nkawm:Tsim cov kab ke kuaj xyuas ib txwm los tsom rau kev yaig ntawm cov inlet yeeb nkab seem

Lub installation specification tau sib xyaw ua ke rau ISO 5199 "cov kev qhia tshwj xeeb rau centrifugal twj rau centrifugal twj rau centrifugal twj rau centrifugal twj rau centrify, chemical thiab petrochemical Industries".
