Kusankha pampu yoyenera ya centrifugal ndikofunikira pakuwonetsetsa kuti dongosolo likuyenda bwino komanso lodalirika.

Zotsatirazi ndi zatsatanetsatane komanso masitepe pakusankha pampu ya centrifugal:

1.Sankhani magawo ofunikira

1.1 Kuyenda (Q)

• tanthauzo: Kuchuluka kwa madzi operekedwa ndi pampu ya centrifugal pa nthawi ya unit.
• unit: Kiyubiki mita pa ola (m3/h) kapena malita pa sekondi (L/s).
• Njira yodziwira: Zimatsimikiziridwa malinga ndi mapangidwe apangidwe ndi zosowa zenizeni za dongosolo. Kawirikawiri, kuthamanga kwa madzi kuyenera kukwaniritsa kufunikira kwa madzi pamalo ovuta kwambiri.
  • nyumba yogona: Nthawi zambiri 10-50 m3/h.
  • nyumba yamalonda: Nthawi zambiri 30-150 m3/h.
  • mafakitale: Nthawi zambiri 50-300 m3/h.

1.2 Kwezani (H)

• tanthauzo: Mapampu a centrifugal amatha kukweza kutalika kwamadzi.
• unitmita (m).
• Njira yodziwira: Kuwerengedwa motengera kutalika kwa dongosolo, kutalika kwa chitoliro ndi kutayika kwa kukana. Mutu uyenera kukhala ndi mutu wosasunthika (kutalika kwa nyumba) ndi mutu wokhazikika (kutayika kwa mapaipi).
  • Nyamulani mwakachetechete: Kutalika kwa dongosolo.
  • kusuntha lift: Kutalika ndi kukana kutayika kwa payipi, kawirikawiri 10% -20% ya mutu wosasunthika.

1.3 Mphamvu (P)

• tanthauzo: Mphamvu ya centrifugal pump motor.
• unit: kilowatt (kW).
• Njira yodziwira: Kuwerengera mphamvu ya mphamvu ya mpope potengera kuthamanga ndi mutu, ndikusankha mphamvu yamoto yoyenera.
  • Fomula yowerengera:P = (Q × H) / (102 × η)
    • Q: Mayendedwe (m3/h)
    • H: Kwezani (m)
    • η: Kuthamanga kwapampu (nthawi zambiri 0.6-0.8)

• zowononga: Kuwonongeka kwa sing'anga, sankhani zinthu zopopera zoyenera.

2.Sankhani mtundu wa mpope

2.1 Pampu yapakati pagawo limodzi

• Mawonekedwe: Kapangidwe kosavuta, ntchito yosalala komanso kuchita bwino kwambiri.
• Zochitika zoyenera: Yoyenera pamadzi ambiri operekera madzi ndi ngalande.

2.2 Pampu yamagawo angapo a centrifugal

• Mawonekedwe: Kupyolera mu ma impellers angapo omwe amagwirizanitsidwa mndandanda, madzi okwera kwambiri amapezeka.
• Zochitika zoyenera: Yoyenera nthawi yofuna kukwezedwa kwambiri, monga madzi akunyumba zazitali.

2.3 Pampu yodzipangira yokha centrifugal

• Mawonekedwe: Ndi ntchito yodzipangira yokha, imatha kuyamwa madzi mukangoyamba.
• Zochitika zoyenera: Yoyenera pamadzi okwera pansi komanso makina ochotsera madzi.

2.4 Pampu yoyamwa kawiri ya centrifugal

• Mawonekedwe: Mapangidwe olowera m'mbali awiri amadzi amatha kupereka kuthamanga kwakukulu komanso kukweza kwakukulu pa liwiro lotsika.
• Zochitika zoyenera: Yoyenera kuyenda kwakukulu ndi mitu yayikulu, monga madzi amtawuni komanso madzi akumafakitale.

3.Sankhani zinthu zopopera

3.1 Pampu zakuthupi

• chitsulo chachitsulo: Zinthu wamba, zoyenera nthawi zambiri.
• Chitsulo chosapanga dzimbiri: Kukana kwamphamvu kwa dzimbiri, koyenera pazofalitsa zowononga komanso nthawi zokhala ndi ukhondo wambiri.
• mkuwa: Kukana bwino kwa dzimbiri, koyenera madzi a m'nyanja ndi zinthu zina zowononga.

3.2 Impeller zinthu

• chitsulo chachitsulo: Zinthu wamba, zoyenera nthawi zambiri.
• Chitsulo chosapanga dzimbiri: Kukana kwamphamvu kwa dzimbiri, koyenera pazofalitsa zowononga komanso nthawi zokhala ndi ukhondo wambiri.
• mkuwa: Kukana bwino kwa dzimbiri, koyenera madzi a m'nyanja ndi zinthu zina zowononga.

4.Sankhani kupanga ndi chitsanzo

• Kusankha mtundu: Sankhani mitundu yodziwika bwino kuti mutsimikizire mtundu wa malonda ndi ntchito zogulitsa pambuyo pake.
• Kusankhidwa kwachitsanzo:Sankhani chitsanzo choyenera kutengera magawo ofunikira ndi mtundu wa mpope. Onani zolemba zamalonda ndi chidziwitso chaukadaulo choperekedwa ndi mtunduwo.

5.Mfundo zina

5.1 Kugwira ntchito moyenera

• tanthauzo: Mphamvu kutembenuka mphamvu ya mpope.
• Sankhani njira: Sankhani pampu yokhala ndi mphamvu zambiri kuti muchepetse ndalama zogwirira ntchito.

5.2 Phokoso ndi kugwedezeka

• tanthauzo: Phokoso ndi kugwedezeka komwe kumapangidwa pamene mpope ikuyenda.
• Sankhani njira: Sankhani pampu yokhala ndi phokoso lochepa komanso kugwedezeka kuti muwonetsetse malo ogwirira ntchito bwino.

5.3 Kusamalira ndi chisamaliro

• tanthauzo: Kukonza pampu ndi ntchito zofunika.
• Sankhani njira: Sankhani pampu yosavuta kusamalira ndi kusamalira kuchepetsa ndalama zosamalira.

6.Kusankha zochitika

Tangoganizani kuti pampu ya centrifugal iyenera kusankhidwa panyumba yokwera kwambiri Zofunikira zenizeni ndi izi:

• kuyendaKuthamanga: 40m3 / h
• Kwezanikutalika: 70m
• mphamvu: Mawerengedwe potengera mlingo otaya ndi mutu

6.1 Sankhani mtundu wa mpope

• Multistage centrifugal pump: Yoyenera ku nyumba zokhalamo zapamwamba komanso zokhoza kupereka madzi okwera kwambiri.

6.2 Sankhani zinthu zopopera

• Pampu thupi zakuthupi: Chitsulo choponyera, choyenera nthawi zambiri.
• Impeller zakuthupi: Chitsulo chosapanga dzimbiri, kukana dzimbiri mwamphamvu.

6.3 Sankhani mtundu ndi mtundu

• Kusankha mtundu: Sankhani zopangidwa zodziwika bwino, monga Grundfos, Wilo, Southern Pump, etc.
• Kusankhidwa kwachitsanzo: Sankhani chitsanzo choyenera kutengera magawo ofunikira ndi bukhu lamankhwala loperekedwa ndi mtunduwo.

6.4 Mfundo zina

• Kugwira ntchito moyenera: Sankhani pampu yokhala ndi mphamvu zambiri kuti muchepetse ndalama zogwirira ntchito.
• Phokoso ndi kunjenjemera: Sankhani pampu yokhala ndi phokoso lochepa komanso kugwedezeka kuti muwonetsetse malo ogwirira ntchito bwino.
• Kusamalira ndi chisamaliro: Sankhani pampu yosavuta kusamalira ndi kusamalira kuchepetsa ndalama zosamalira.

Kupyolera mu malangizowa mwatsatanetsatane osankhidwa ndi deta, mukhoza kuonetsetsa kuti pampu yoyenera ya centrifugal imasankhidwa kuti ikwaniritse zofunikira za kayendedwe ka madzi ndikuonetsetsa kuti ikhoza kupereka madzi okhazikika komanso odalirika pa ntchito za tsiku ndi tsiku.
