Pampu za centrifugalndi zinthu zofunika m'mafakitale osiyanasiyana, zomwe zimagwiritsidwa ntchito kunyamula madzi kudzera m'makina. Amabwera m'mapangidwe osiyanasiyana kuti agwirizane ndi zosowa zenizeni, ndipo kusiyana kumodzi kwakukulu kuli pakati pa choyikapo chimodzi (kukoka kumodzi) ndi mapampu amagetsi awiri (woyamwa kawiri). Kumvetsetsa kusiyana kwawo ndi ubwino wake kungathandize posankha pampu yoyenera pa ntchito zinazake.
Pampu Yoyamwa Imodzi: Mapangidwe ndi Makhalidwe
Mapampu oyamwa amodzi, omwe amadziwikanso kuti mapampu akumapeto, amakhala ndi cholumikizira chomwe chimapangidwa kuti chikoke madzi kuchokera mbali imodzi yokha. Kapangidwe kameneka kamapangitsa kuti choyikapocho chizikhala ndi mbale zoyambira kutsogolo ndi kumbuyo. Zigawo zazikuluzikulu zimaphatikizapo chopondera chothamanga kwambiri komanso choyikapo chopopera chofanana ndi nyongolotsi. Choyikapo nyali, chomwe chimakhala ndi mavane angapo okhota kumbuyo, chimakhazikika pa shaft ya mpope ndikuyendetsedwa ndi mota kuti chizungulire mwachangu. Doko loyamwitsa, lomwe lili pakatikati pa pompopompo, limalumikizidwa ndi chitoliro choyamwa chokhala ndi valavu yapansi ya njira imodzi, pomwe chotulutsa chotulutsa pamphepete mwa pampu chimalumikizana ndi chitoliro chotulutsa ndi valavu yowongolera.

Ubwino wa Mapampu Amodzi Amodzi
Mapampu akuyamwa amodzi ali ndi maubwino angapo:
Kuphweka ndi Kukhazikika: Mapangidwe awo osavuta amaonetsetsa kuti ntchitoyo ikuyenda bwino komanso kukonza kosavuta. Amakhala ndi malo ochepa, zomwe zimapangitsa kuti zikhale zosavuta kuziyika.
Kugwiritsa Ntchito Ndalama: Mapampuwa ndi otsika mtengo, okhala ndi zotsika mtengo zoyambira komanso mitengo yabwino, zomwe zimapangitsa kuti athe kupezeka pazogwiritsa ntchito zosiyanasiyana.
Kuyenerera Kugwiritsa Ntchito Pang'onopang'ono: Mapampu oyamwa amodzi ndi abwino pazochitika zomwe zimafuna kuti madzi azitsika, monga ulimi wothirira ndi njira zochepa zoperekera madzi.
Komabe, mapampu oyamwa amodzi amakhala ndi zoletsa zina:
Axial Force ndi Bearing Load: Kapangidwe kake kamapanga mphamvu yayikulu ya axial, zomwe zimapangitsa kuti azinyamula katundu wambiri. Izi zitha kupangitsa kuti ma bearing achuluke komanso kung'ambika, zomwe zingachepetse moyo wa mpope.
Pampu Yoyamwa Pawiri: Mapangidwe ndi Makhalidwe
Pampu zoyamwa kawiriamapangidwa ndi choyikapo chomwe chimakoka madzi kuchokera kumbali zonse ziwiri, kugwirizanitsa bwino mphamvu za axial ndikulola kuti azithamanga kwambiri. Choyimiritsacho chimapangidwa molingana, ndi madzi olowera mbali zonse ndikusintha mkati mwa mpope. Mapangidwe ofananirawa amathandizira kuchepetsa kuthamanga kwa axial ndikunyamula katundu, kuonetsetsa kuti ntchito ikuyenda bwino.
Pampu zoyamwa kawiriakupezeka mumitundu yosiyanasiyana, kuphatikiza chopingasa chogawanitsa chopingasa, chogawanika choyimirira, ndi mapampu oyamwa pawiri. Mtundu uliwonse umapereka maubwino ake ndipo umagwirizana ndi mapulogalamu ena:
1. Mapampu a Horizontal Split Case: Mapampuwa ali ndi volute yomwe imagawika mopingasa, zomwe zimapangitsa kuti zikhale zosavuta kuzigwiritsa ntchito koma zimafuna malo ofunikira komanso zida zonyamulira zolemetsa kuti achotse gawo lapamwamba la casing.
2. Mapampu Omwe Agawanika Kwambiri: Ndi chivundikiro chogawanika choyima ndi chochotsamo, mapampuwa amatenga malo ocheperako ndipo ndi osavuta kugwiritsa ntchito, makamaka pokonzekera kumene kuyamwa ndi kutulutsa mipope kumakhala koyima.
3. Mapampu Olowera Pawiri Pawiri: Zomwe zimagwiritsidwa ntchito pamapaipi akuluakulu, mapampuwa amatha kukhala ovuta kugwira ntchito chifukwa amafuna kuti injiniyo ichotsedwe kuti ipeze zida zamkati.
Ubwino wa Pampu Zoyamwa Pawiri
Mapampu oyamwa kawiri amapereka maubwino angapo:
Mitengo Yoyenda Kwambiri: Mapangidwe awo amalola kuti azithamanga kwambiri, kuwapangitsa kukhala oyenera kugwiritsa ntchito zofunikira kwambiri monga machitidwe a HVAC (2000 GPM kapena 8-inch pump size).
Kuchepetsa kwa Axial Thrust: Pogwirizanitsa mphamvu za axial, mapampuwa sakhala ndi kuwonongeka pang'ono ndi kung'ambika pamabere, zomwe zimathandiza kuti moyo ukhale wautali (mpaka zaka 30).
Anti-Cavitation: Mapangidwewo amachepetsa chiopsezo cha cavitation, kupititsa patsogolo mphamvu ya mpope ndi ntchito yake.
Kusinthasintha: Ndi masinthidwe angapo omwe alipo, mapampu oyamwa kawiri amatha kutengera zofunikira zosiyanasiyana zamapaipi, kuwapangitsa kukhala oyenera kumafakitale monga migodi, madzi akumatauni, malo opangira magetsi, ndi ntchito zazikulu zamadzi.

Kusankha Pakati pa Single ndiMapampu Oyamwa Pawiri
Posankha pakati pa mapampu oyamwa amodzi kapena awiri, zinthu zingapo ziyenera kuganiziridwa:
1. Zofunikira Zoyenda: Pazogwiritsa ntchito zomwe zili ndi zofunikira zochepa zoyenda, mapampu amodzi oyamwa amakhala okwera mtengo komanso okwanira. Pazofuna zothamanga kwambiri, mapampu oyamwa kawiri ndi abwino.
2. Malo ndi Kuyika: Mapampu oyamwa kawiri, makamaka mapangidwe ang'onoang'ono ogawanika, amatha kusunga malo ndipo ndi osavuta kusamala poyika mothina.
3. Mtengo ndi Kukonza: Mapampu okokera amodzi ndi otsika mtengo komanso osavuta kuwasamalira, kuwapangitsa kukhala abwino kwambiri pantchito zomwe zimagwirizana ndi bajeti. Mosiyana ndi izi, mapampu oyamwa kawiri, ngakhale okwera mtengo poyambilira, amapereka moyo wautali wautumiki ndikuchita bwino pamapulogalamu ofunikira.

Mapeto
Mwachidule, mapampu oyamwa amodzi komanso awiri ali ndi maubwino ake ndipo ndi oyenerera kugwiritsa ntchito mosiyanasiyana. Mapampu akuyamwa amodzi ndi abwino kuti aziyenda pang'onopang'ono, zochitika zotsika mtengo, pomwe mapampu akuyamwa kawiri ndi abwino kuti azithamanga kwambiri, mapulojekiti anthawi yayitali omwe amafunikira ntchito yodalirika komanso yodalirika. Kumvetsetsa kusiyana kumeneku kumatsimikizira kusankhidwa kwa pampu yoyenera pachofunikira chilichonse, kukhathamiritsa ntchito komanso kutsika mtengo.
