Mfundo Zaumisiri ndi Zoyeserera Zaumisiri pa Kuyika kwa Eccentric Reducers pa Inlet of Centrifugal Pumps:

1. Mfundo Zosankha Njira Yoyikira Njira yoyika zochepetsera eccentric polowera mapampu apakati akuyenera kuganizira mozama za mphamvu zamadzimadzi ndi zoteteza pazida, makamaka potsatira chisankho cha zinthu ziwiri:

Chofunika Kwambiri pa Chitetezo cha Cavitation:
Pamene dongosolo la Net Positive Suction Head (NPSH) m'mphepete silokwanira, Top-Flat Orientation iyenera kutengedwa kuti iwonetsetse kuti pansi pa chitoliro kumatsika mosalekeza kuti apewe kudzikundikira kwamadzi komwe kungayambitse cavitation.
Zofunikira za Liquid Discharge:Pakafunika kukwera kwa condensate kapena mapaipi, Kuwongolera kwa Pansi-Flat kungasankhidwe kuti kuthandizire kutulutsa kwamadzimadzi.

2.the kusanthula pamwamba lathyathyathya unsembe luso
Ubwino wa Fluid Mechanics:
● Imathetsa mphamvu ya flexitank: Imasunga pamwamba pa chubu mosalekeza kupeŵa kusanja kwamadzimadzi komanso kumachepetsa chiopsezo cha airbag.
● Kugawa kwamayendedwe okhathamira: Kuwongolera kusintha kwamadzimadzi osalala ndikuchepetsa mphamvu ya chipwirikiti pafupifupi 20-30%
Njira ya anti-cavitation:
● Pitirizani kukhala ndi mayendedwe abwino: pewani kupanikizika kwanuko kuti kusatsike pansi pa mphamvu ya nthunzi yochuluka ya sing'anga.
● Kuchepetsa kuthamanga kwa pulsation: Kumathetsa madera opangira vortex ndikuchepetsa mwayi wa cavitation
Thandizo la miyezo yapadziko lonse lapansi:
● Muyezo wa API 610 umafunika: Zigawo za inlet eccentric ziyenera kukhazikitsidwa mwamakonda pamlingo wapamwamba
● Hydraulic Institute Standard: Yalangizidwa kuti ikhale yokhazikika ngati muyezo wa cavitation resistance

3.Mawonekedwe ogwiritsira ntchito oyika pansi-lathyathyathya
Mikhalidwe yapadera yogwirira ntchito:
● Condensate Discharge System: Imatsimikizira kutulutsa koyenera kwa condensate
● Kuwotcha kwa chitoliro: kumathandizira kuchotsa zinyalala
Malipiro a Design:
● Mavavu otulutsa mpweya amafunikira
● M'mimba mwake wa chitoliro cholowera uyenera kuonjezedwa ndi magiredi 1-2
● Ndikoyenera kukhazikitsa mfundo zowunikira

4.the unsembe malangizo tanthauzo muyezo
Kutanthauziridwa pogwiritsa ntchito ASME Y14.5M Makulidwe a Geometric ndi Kulekerera:
Kuyika kwapamwamba:ndege ya mbali ya eccentric imasungunuka ndi khoma lamkati la pamwamba pa chitoliro
Kuyika pansi-lathyathyathya:ndege ya gawo la eccentric imasungunuka ndi khoma lamkati la pansi pa chitoliro
Zindikirani:Mu ntchito yeniyeni, tikulimbikitsidwa kugwiritsa ntchito 3D laser scanning kuti mutsimikizire kulondola kwa kukhazikitsa.

5.Maganizo oyendetsera polojekiti
Kayeseleledwe ka manambala:Kusanthula kwa Cavitation allowance (NPSH) pogwiritsa ntchito pulogalamu ya CFD
Kutsimikizira patsamba:The homogeneity wa otaya liwiro kugawa wapezeka ndi akupanga otaya mita
Pulogalamu yowunikira:Ikani zowonera kupanikizika ndi zowunikira kugwedezeka kuti muzitsatira kwa nthawi yayitali
Njira yosamalira:Khazikitsani dongosolo loyendera nthawi zonse kuti liziyang'ana pakukokoloka kwa gawo la chitoliro cholowera

Mafotokozedwe oyikawa adaphatikizidwa mu ISO 5199 "Technical Specification for Centrifugal Pump" ndi GB/T 3215 "General Technical Conditions for Centrifugal Pump for Refinery, Chemical and Petrochemical Industries".
