Mfundo zokhazikitsira chotsitsa madzi cha pampu ya centrifugal

Mafotokozedwe aukadaulo ndi Kusanthula kwa Machitidwe a Uinjiniya pakukhazikitsa kwa Eccentric Reducers pa Inlet of Centrifugal Pumps:

1. Mfundo Zosankha Malangizo Okhazikitsa Malangizo Okhazikitsa Malangizo okhazikitsa ma eccentric reducers pamalo olowera mapampu a centrifugal ayenera kuganizira mozama za mphamvu zamadzimadzi ndi zosowa za chitetezo cha zida, makamaka kutsatira chitsanzo cha zinthu ziwiri:

Chofunika Kwambiri Pakuteteza Kutsekeka kwa Mitsempha:
Ngati malire a Net Positive Suction Head (NPSH) a dongosololi sali okwanira, kuyenera kutsatiridwa kuti pansi pa chitolirocho pakhale potsika mosalekeza kuti madzi asasonkhanitsidwe omwe angayambitse kutsekeka kwa chitolirocho.
Zofunikira pa Kutulutsa Madzi:Ngati pakufunika kutsuka madzi ndi condensate kapena pipeline, njira yolowera pansi ikhoza kusankhidwa kuti ithandize kutulutsa madzi.

2. kusanthula kwa ukadaulo wapamwamba wokhazikitsa
Ubwino wa Makina Opangira Madzi:
● Zimachotsa mphamvu ya flexitank: Zimasunga pamwamba pa chubu mosalekeza kuti madzi asakanikirane komanso zimachepetsa chiopsezo cha kusonkhana kwa ma airbag.
● Kugawa bwino liwiro la kuyenda: Kumatsogolera kusintha kwa madzi bwino komanso kuchepetsa mphamvu ya kugwedezeka ndi pafupifupi 20-30%
Njira yoletsa kutsekeka kwa m'mimba:
● Sungani mpweya wabwino: letsani kuti mpweya wochuluka usamatsike pansi pa mpweya wokwanira wa sing'anga
● Kuchepetsa kuthamanga kwa magazi: Kumachotsa malo opangira ma vortex ndikuchepetsa mwayi woti cavitation ichitike.
Miyezo yapadziko lonse lapansi imathandizira:
● Muyezo wa API 610 umafuna kuti: Ziwalo zolowera ziyenera kuyikidwa bwino pamwamba
● Hydraulic Institute Standard: Yoyenera kukhazikitsidwa mopanda kugwedezeka ngati muyezo wotsutsana ndi cavitation

3. Zochitika zomwe zingagwiritsidwe ntchito pokhazikitsa pansi panthaka
Mikhalidwe yapadera yogwirira ntchito:
● Dongosolo Lotulutsa Madzi Oundana: Limaonetsetsa kuti madzi oundana amatulutsa madzi bwino
● Chitoliro chotsukira mapaipi: chimathandiza kuchotsa matope
Malipiro a Kapangidwe:
● Ma valve otulutsa utsi amafunika
● M'mimba mwake wa chitoliro cholowera uyenera kuwonjezeredwa ndi magiredi 1-2
● Ndikofunikira kukhazikitsa malo owunikira kuthamanga kwa magazi

4. muyezo wofotokozera malangizo okhazikitsa
Kutanthauzidwa pogwiritsa ntchito ASME Y14.5M Miyeso ya Geometric ndi Kulekerera Muyezo:
Kukhazikitsa pamwamba pa denga:gawo la eccentric lili lozungulira ndi khoma lamkati la pamwamba pa chitoliro
Kukhazikitsa pansi pa denga:gawo la eccentric lili lozungulira ndi khoma lamkati la pansi pa chitolirocho
Zindikirani:Mu polojekiti yeniyeni, tikukulimbikitsani kugwiritsa ntchito 3D laser scanning kuti mutsimikizire kulondola kwa kukhazikitsa.

5. Malangizo okhudza kukhazikitsa polojekiti
Kuyerekezera manambala:Kusanthula kwa Cavitation Allowance (NPSH) pogwiritsa ntchito pulogalamu ya CFD
Kutsimikizira pamalopo:Kugwirizana kwa kugawa kwa liwiro la kuyenda kwa madzi kumadziwika ndi chipangizo choyezera kuyenda kwa madzi cha ultrasound
Pulogalamu yowunikira:Ikani masensa owunikira kuthamanga ndi zowunikira kugwedezeka kuti muzitsatira nthawi yayitali
Njira yosamalira:Khazikitsani njira yowunikira nthawi zonse kuti iyang'ane kuwonongeka kwa gawo la mapaipi olowera

Mafotokozedwe a kukhazikitsa aphatikizidwa mu ISO 5199 “Mafotokozedwe Aukadaulo a Mapampu a Centrifugal” ndi GB/T 3215 “Zofunikira Zaukadaulo za Mapampu a Centrifugal a Makampani Oyeretsera, Mankhwala ndi Petrochemical”.
