IiNkcazo zobuGcisa kunye noHlalutyo lokuSebenza lobuNjineli boFakelo lwe-Eccentric Reducers kwi-Inlet yeePumpu ze-Centrifugal:

1.Imigaqo yokuKhetha uMkhombandlela woFakelo Isalathiso sofakelo lwezinciphisi ze-eccentric kwindawo yokungena iimpompo ze-centrifugal kufuneka ziqwalasele ngokubanzi iimpawu ze-fluid dynamics kunye neemfuno zokhuseleko lwezixhobo, ngokuyintloko ngokulandela imodeli yesigqibo sezinto ezimbini:

Okuphambili kuKhuseleko lweCavitation:
Xa umda we-Net Positive Suction Head (NPSH) yenkqubo ayinelanga, i-Top-Flat Orientation kufuneka yamkelwe ukuqinisekisa ukuba i-bottom yombhobho ihla ngokuqhubekayo ukuze igweme ukuqokelelwa kwamanzi okungakhokelela kwi-cavitation.
IiMfuno zokukhutshelwa kolwelo:Xa kukho imfuneko yokugungxulwa kwe-condensate okanye umbhobho, i-Bottom-Flat Orientation ingakhethwa ukuququzelela ukukhutshwa kwesigaba solwelo.

2.uhlalutyo lweteknoloji yofakelo oluphezulu
Izinto eziluncedo kwi-Fluid Mechanics:
● Iphelisa i-flexitank effect: Igcina umphezulu wetyhubhu ngokuqhubekayo ukunqanda ukuchithwa kwamanzi kunye nokunciphisa umngcipheko wokwakhiwa kwe-airbag.
● Ukuhanjiswa kwesantya sokuqukuqela okulungiselelweyo: Ukukhokela uguqulo olugudileyo lolwelo kunye nokunciphisa ukuqina kwesiphithiphithi malunga ne-20-30%
Indlela yokulwa ne-cavitation:
● Gcina i-gradient yoxinzelelo olulungileyo: thintela uxinzelelo lwendawo ekuweleni ngaphantsi koxinzelelo lomphunga ogcweleyo we-medium.
● Ukunciphisa uxinzelelo lwe-pulsation: Ukuphelisa iindawo zokuvelisa i-vortex kunye nokunciphisa amathuba okuba ne-cavitation
Inkxaso yemigangatho yamazwe ngamazwe:
● Umgangatho we-API 610 ufuna: Amalungu e-Inlet eccentric kufuneka afakwe ngokukhethekileyo kwinqanaba eliphezulu
● Umgangatho weZiko le-Hydraulic: Kunconywa ukunyuswa kweflethi njengomgangatho wokumelana ne-cavitation

3.Iimeko ezisebenzayo zofakelo olusezantsi-flat
Iimeko ezikhethekileyo zokusebenza:
● I-Condensate Discharge System: Iqinisekisa ukukhutshwa ngokufanelekileyo kwe-condensate
● Isekethi yokugungxulwa kwemibhobho: iququzelela ukususwa kwentlenga
Imbuyekezo yoyilo:
● Iivalvu zokuphuma ziyafuneka
● Ububanzi bombhobho wokungena kufuneka kwandiswe ngamabakala angama-1-2
● Kucetyiswa ukuseta iindawo zokubeka iliso loxinzelelo

4.umgangatho wofakelo lwenkcazo yesalathiso
Ichazwe kusetyenziswa i-ASME Y14.5M iMilinganiselo yeJiyometri kunye neMigangatho yoNyamezelo:
Ufakelo olukwiflethi ephezulu:indiza ye-eccentric part is flush kunye nodonga lwangaphakathi lombhobho ophezulu
Ufakelo olusezantsi-mcaba:i-plane ye-eccentric part is flush kunye nodonga lwangaphakathi lwezantsi lombhobho
Phawula:Kwiprojekthi yokwenyani, kucetyiswa ukuba kusetyenziswe ukuskena kwe-laser ye-3D ukuqinisekisa ukuchaneka kofakelo.

5.Iingcebiso zokuphunyezwa kweprojekthi
Ukulinganisa kwamanani:Isibonelelo seCavitation (NPSH) uhlalutyo usebenzisa isoftware yeCFD
Ukuqinisekisa kwisiza:I-homogeneity ye-flow velocity distribution ifunyenwe yi-ultrasonic flow meter
Inkqubo yokubeka iliso:Faka iinzwa zoxinzelelo kunye nabahloli be-vibration ukulandelwa kwexesha elide
Isicwangciso sogcino:Ukuseka inkqubo yokuhlola rhoqo ukuze kugxininise ukukhukuliseka kwecandelo lombhobho wokungena

Inkcazo yokufakela ifakwe kwi-ISO 5199 "Inkcazo yobuGcisa yeePumpu ze-Centrifugal" kunye ne-GB / T 3215 "IiMeko zobuGcisa ngokuBanzi kwiiPumpu ze-Centrifugal zokuCoca, i-Chemical and Petrochemical Industries".
