Magadzirirwo ehunyanzvi uye Ongororo yeMaitiro eUinjiniya yekuisa maEccentric Reducers paInlet yeCentrifugal Pumps:
1. Nheyo dzekusarudza Nheyo yekuisa Nzira yekuisa ma "eccentric reducers" panopinda mapombi e centrifugal inofanira kufunga zvizere nezvehunhu hwe fluid dynamics uye zvinodiwa zvekuchengetedza michina, kunyanya zvichitevera modhi yesarudzo ye "dual-factor:
Chinonyanya Kukosha pakudzivirira Cavitation:
Kana Net Positive Suction Head (NPSH) yesystem isina kukwana, kunofanira kushandiswa nzira yeTop-Flat Orientation kuti pasi pepombi parambe pachidzika kudzivirira kuungana kwemvura kunogona kukonzera cavitation.
Zvinodiwa paKubuda Kwemvura:Kana paine chikonzero chekudziisa mvura inodziya kana kuibvisa mupombi, nzira yekuisa mvura iri pasi pemvura inogona kusarudzwa kuti iite kuti mvura ibude zvakanaka.
2.Kuongororwa kwetekinoroji yepamusoro yekugadza yakatsetseka
Mabhenefiti eFluid Mechanics:
● Inobvisa simba re flexitank: Inoita kuti pamusoro pechubhu parambe pakachena kudzivirira kupatsanurwa kwemvura uye inoderedza njodzi yekuungana kwe airbag.
● Kugoverwa kwekukurumidza kwekuyerera kwakagadziriswa: Kunotungamira kuchinja kwemvura zvakanaka uye kunoderedza kusimba kwemhepo neanenge 20-30%
Maitiro ekudzivirira cavitation:
● Chengetedza kumanikidzwa kwakanaka: kudzivirira kumanikidzwa kwenzvimbo kuti kurege kuderera pasi pekumanikidzwa kwemhepo yakasviba yepakati
● Kuderedza kumanikidzwa kwemhepo: Kunobvisa nzvimbo dzekugadzira mhepo uye kunoderedza mukana wekuti munhu apinde muropa.
Rutsigiro rwemitemo yepasi rose:
● API 610 standard inoda kuti: Zvikamu zvemukati zvisanyanya kupinza zvinofanira kuiswa panzvimbo yepamusoro
● Hydraulic Institute Standard: Inokurudzirwa kuti isatsvedzerere seyakajairika pakudzivirira cavitation
3. Mamiriro ezvinhu anoshanda ekugadzwa kwepasi-pasi
Mamiriro ekushanda akakosha:
● Hurongwa hweKuburitsa Makonzo: Hunoita kuti konzo ibudiswe zvakanaka
● Kufambisa mapaipi: zvinobatsira kubvisa tsvina
Muripo weDhizaini:
● Mavharuvhu ekuburitsa mvura anodiwa
● Dhayamita yepombi yekupinda inofanira kuwedzerwa ne1-2 magiredhi
● Zvinokurudzirwa kuisa nzvimbo dzekutarisa kumanikidzwa
4. tsanangudzo yegwara rekugadzwa
Zvinotsanangurwa uchishandisa ASME Y14.5M Geometric Dimensions and Tolerances Standard:
Kuiswa kwepamusoro-soro:chikamu chechinhu chisina kujairika chakapfava nemadziro emukati mepombi yepamusoro
Kuiswa kwepasi-rakatsetseka:chikamu chechinhu chisina kusimba chakapfava nemadziro emukati pezasi pepombi
Cherechedza:Muchirongwa chaicho, zvinokurudzirwa kushandisa 3D laser scanning kuti uone kana kuiswa kwacho kwakarurama.
5. Mazano ekuita kuti chirongwa chiitwe
Kufungidzira kwenhamba:Kuongororwa kweCavitation allowance (NPSH) uchishandisa software yeCFD
Kusimbiswa panzvimbo:Kuenzana kwekupararira kwekukurumidza kwekufamba kwemvura kunowanikwa ne ultrasonic flow meter.
Chirongwa chekutarisa:Isa masensa ekumanikidza uye mamonita ekutetepa kuti utarise kwenguva refu
Maitiro ekugadzirisa:Gadzirai nzira yekuongorora nguva dzose kuti mutarise pakukura kwechikamu chepombi inopinza
Tsanangudzo yekuisa yakabatanidzwa muISO 5199 “Technical Specification yeCentrifugal Pomps” uye GB/T 3215 “General Technical Conditions yeCentrifugal Pomps yeRefinery, Chemical and Petrochemical Industries”.
