Izicaciso Zobuchwepheshe Nokuhlaziywa Komkhuba Wobunjiniyela Wokufakwa Kwezinciphisi Ze-Eccentric Ku-Inlet of Centrifugal Pumps:

1.Izimiso Zokukhetha Isikhombisi-ndlela Sokufaka Isiqondiso sokufakwa kwezinciphisi ezi-eccentric endaweni yokungena yamaphampu amaphakathi kufanele sicabangele kabanzi izici zokuguquguquka koketshezi kanye nezidingo zokuvikela okokusebenza, ngokuyinhloko kulandele imodeli yesinqumo sezinto ezimbili:

Okubalulekile Kokuvikela I-Cavitation:
Uma imajini ye-Net Positive Suction Head (NPSH) yohlelo inganele, kufanele kuthathwe i-Top-Flat Orientation ukuze kuqinisekiswe ukuthi iphansi lepayipi liyehla ngokuqhubekayo ukuze kugwenywe ukunqwabelana koketshezi okungaholela ku-cavitation.
Izidingo Zokukhipha Uketshezi:Uma kunesidingo sokugungiswa kwe-condensate noma ipayipi, i-Bottom-Flat Orientation ingakhethwa ukuze kube lula ukukhipha kwesigaba soketshezi.

2.ukuhlaziywa kobuchwepheshe bokufakwa kwe-flat top
Izinzuzo ze-Fluid Mechanics:
● Iqeda umphumela we-flexitank: Igcina ingaphezulu leshubhu ngokuqhubekayo ukuze igweme ukuhlukaniswa koketshezi futhi inciphisa ingozi yokwakheka kwe-airbag
● Ukusabalalisa kwesivinini sokugeleza okuthuthukisiwe: Iqondisa ukuguquka koketshezi olubushelelezi futhi yehlise ukushuba kwesiphithiphithi cishe ngo-20-30%
Indlela ye-anti-cavitation:
● Gcina i-gradient ephozithivu yokucindezela: vimbela ingcindezi yendawo ukuthi ingabi ngaphansi komfutho womhwamuko ogcwele wento ephakathi.
● Ukunciphisa ingcindezi: Iqeda izindawo zokukhiqiza i-vortex futhi inciphisa amathuba okuba ne-cavitation
Ukusekelwa kwamazinga omhlaba:
● Izinga le-API 610 lidinga: Izingxenye ze-inlet eccentric kufanele zifakwe ngokukhethayo ezingeni eliphezulu
● I-Hydraulic Institute Standard: Kunconyelwe ukukhwezwa okuyisicaba njengokujwayelekile kokumelana ne-cavitation

3.Izimo ezisebenzayo zokufakwa kwefulethi elingaphansi
Izimo zokusebenza ezikhethekile:
● I-Condensate Discharge System: Iqinisekisa ukukhipha okusebenzayo kwe-condensate
● Isekhethi yokugezwa kwamapayipi: kusiza ukususwa kwenhlabathi
Isinxephezelo Sedizayini:
● Kudingeka amavalvu okukhipha umoya
● Ububanzi bepayipi lokungena kufanele bukhuliswe ngamabanga angu-1-2
● Kunconywa ukusetha amaphuzu okuqapha ingcindezi

4.incazelo yesiqondiso sokufaka indinganiso
Kuchazwa kusetshenziswa i-ASME Y14.5M Ubukhulu beJiyomethri kanye nezinga lokubekezelela:
Ukufakwa kwefulethi eliphezulu:indiza yengxenye eccentric ishaywa ngodonga lwangaphakathi lwepayipi eliphezulu
Ukufakwa kwephansi eliphansi:indiza yengxenye eccentric ishaywa ngodonga lwangaphakathi ngaphansi kwepayipi
Qaphela:Kuphrojekthi yangempela, kunconywa ukusebenzisa ukuskena kwe-laser ye-3D ukuze uqinisekise ukunemba kokufakwa.

5.Iziphakamiso zokuqaliswa kwephrojekthi
Ukulingisa kwezinombolo:Ukuhlaziywa kwe-Cavitation allowance (NPSH) kusetshenziswa isoftware ye-CFD
Ukuqinisekiswa kwesayithi:I-homogeneity ye-flow velocity distribution itholwa imitha yokugeleza ye-ultrasonic
Uhlelo lokuqapha:Faka izinzwa zokucindezela kanye neziqaphi zokudlidliza zokulandelela isikhathi eside
Isu lokunakekela:Sungula uhlelo lokuhlola olujwayelekile ukuze ugxile ekugugulekeni kwengxenye yepayipi elingenayo

Ukucaciswa kokufakwa kufakwe ku-ISO 5199 “Ukucaciswa Kobuchwepheshe Kwamaphampu Ase-Centrifugal” kanye ne-GB/T 3215 “Izimo Zobuchwepheshe Ezivamile Zamaphampu Ase-Centrifugal Embonini Yokuhluza, Amakhemikhali kanye Neye-Petrochemical”.
