Pampu ya centrifugal ikayambika, palibe madzi papaipi yotulutsira pampu, kotero palibe kukana kwa mapaipi komanso kukana kukweza kutalika. Pambuyo poyambitsa pampu ya centrifugal, mutu wa mpope wa centrifugal ndi wotsika kwambiri ndipo kutuluka kwake kumakhala kwakukulu kwambiri. Panthawiyi, kutulutsa kwa injini yapampu (mphamvu ya shaft) ndi yaikulu kwambiri (malinga ndi makina opangira pampu), zomwe zimakhala zosavuta kuzidzaza, zomwe zingawononge makina a pampu ndi dera. Chifukwa chake, tsekani valavu yotulutsira poyambira, Kuti pampu igwire ntchito bwino. Kutseka valavu yotuluka ndi kofanana ndi kukhazikitsa mwamphamvu kukana kwa chitoliro. Pampuyo ikagwira ntchito bwino, yambani pang'onopang'ono valavu kuti pampu igwire ntchito mwachizolowezi pang'onopang'ono motsatira lamulo la mayendedwe ake.
Mfundo ziwiri ziyenera kutsimikiziridwa musanayambe pampu ya centrifugal:
1. Dzazani mpope wa mpope ndi madzi kuti mupange vacuum;
2. Valve pa chitoliro cha madzi ayenera kutsekedwa kuti pampu yamadzi isapangitse kuyenda, zomwe zingachepetse galimoto yoyambira panopa ndikuthandizira kuyamba bwino kwa mpope wa madzi. Ndi kuyamba kosalala kwa mpope wamadzi, valve yachipata iyenera kutsegulidwa pang'onopang'ono komanso panthawi yake.
Pampu ya centrifugal imadalira kuyamwa kwa vacuum komwe kumapangidwa ndi mphamvu yapakati ya impeller kukweza madzi. Choncho, poyambitsa pampu ya centrifugal, choyamba muyenera kutseka valavu ndikudzaza madzi. Pamene mlingo wa madzi umaposa malo a choyikapo, mpope wa centrifugal ukhoza kuyambika pokhapokha mpweya wa pampu wa centrifugal utatulutsidwa. Pambuyo poyambira, vacuum imapangidwa mozungulira chopondera kuti chiyamwe madzi, omwe amatha kutsegulidwa okha ndikukweza madzi. Chifukwa chake, valavu yotuluka iyenera kutsekedwa poyamba.
Za pampu ya centrifugal:
Pampu ya centrifugal ndi pampu ya vane, yomwe imadalira chopondera chozungulira. Pozungulira, chifukwa cha kugwirizana pakati pa tsamba ndi madzi, tsambalo limatulutsa mphamvu zamakina kumadzimadzi, kuti mphamvu yamadzimadzi iwonjezeke kuti ikwaniritse cholinga chotumizira madziwo. Pampu ya centrifugal ili ndi izi:
1. Pali malire amutu omwe amapangidwa ndi pampu ya centrifugal pa liwiro linalake. Kuthamanga kwa malo ogwiritsira ntchito ndi mphamvu ya shaft kumadalira momwe chipangizochi chikugwirizanirana ndi mpope (kusiyana kwa msinkhu, kusiyana kwa kuthamanga ndi kutaya mapaipi). Mutu umasiyana ndi kuyenda.
2. Kugwira ntchito mokhazikika, kusuntha kosalekeza, ndipo palibe pulsation ya kutuluka ndi kupanikizika.
3. Nthawi zambiri, ilibe mphamvu yodzipangira yokha. M'pofunika kudzaza mpope ndi madzi kapena vacuyu payipi musanayambe kugwira ntchito.
4. Pampu ya centrifugal imayambika pamene valavu yotulutsa payipi yatsekedwa, ndipo pampu ya vortex ndi axial flow pump imayambika pamene valavu imatsegulidwa mokwanira kuti achepetse mphamvu yoyambira.
Pampu isanayambe, chipolopolo cha mpope chimadzazidwa ndi madzi onyamulidwa; Pambuyo poyambitsa, choyikapocho chimazungulira pa liwiro lalikulu loyendetsedwa ndi shaft, ndipo madzi omwe ali pakati pa masambawo ayeneranso kuzungulira nawo. Pansi pa mphamvu ya centrifugal, madzi amaponyedwa kuchokera pakati pa chopondera kupita kumphepete kwakunja ndipo amapeza mphamvu, ndikusiya m'mphepete mwa kunja kwa choyikapo pa liwiro lalikulu ndikulowa mu nyumba ya volute pump.
Mu volute, madziwo amatsika chifukwa cha kukula kwapang'onopang'ono kwa njira yotuluka, amasintha gawo la mphamvu ya kinetic kukhala mphamvu yamphamvu yokhazikika, ndipo pamapeto pake amathamangira mu chitoliro chotulutsa pamphamvu kwambiri ndikutumizidwa komwe kumafunika. Pamene madzi akuyenda kuchokera pakati pa choyikapocho kupita kumphepete kwakunja, mpweya wina umapangidwa pakati pa choyikapocho. Popeza kuthamanga pamwamba pa mlingo wamadzimadzi wa thanki yosungiramo ndi yaikulu kuposa kuthamanga kwa polowera papope, madziwo amakanikizidwa mosalekeza mu choyikapocho. Zitha kuwoneka kuti malinga ngati choyikapochi chikuzungulira mosalekeza, madziwo amayamwa ndikutulutsidwa mosalekeza.
Kuyambitsa mapampu ena centrifugal:
Zomwe tatchulazi ndi mapampu apakati. Kwa mitundu ina ya mapampu, zinthu zili motere:
Makhalidwe akuluakulu oyambira a 01 axial flow pump
Pamene valavu yotseguka yotseguka ikuyamba pampu ya axial yothamanga, mphamvu ya shaft ndiyokwera kwambiri pansi pa zero, yomwe ndi 140% ~ 200% ya mphamvu ya shaft, ndipo mphamvu ndiyo yochepa kwambiri. Chifukwa chake, kuti muchepetse kuyambika kwamphamvu, mawonekedwe oyambira mphamvu ya shaft ayenera kukhala oyambira kwambiri (mwachitsanzo, valavu yotseguka yoyambira).
02 zoyambira zapampu yosakanikirana
Pampu yosakanikirana ikayamba ndi valavu yotseguka, mphamvu ya shaft ili pakati pa mapampu awiri omwe ali pamwambawa pansi pa zero, zomwe ndi 100% ~ 130% ya mphamvu yovotera. Choncho, makhalidwe oyambira a pampu osakanikirana ayeneranso kukhala pakati pa mapampu awiri omwe ali pamwambawa, ndipo ndi bwino kuyamba ndi valavu yotseguka.
03 zoyambira pampu ya vortex
Pampu ya vortex yotseguka yotseguka imakhala ndi mphamvu yayikulu kwambiri ya shaft pansi pa zero, yomwe ndi 130% ~ 190% ya mphamvu yovotera. Choncho, mofanana ndi axial flow pump, khalidwe loyambira la pampu ya vortex liyenera kukhala loyambira kwambiri (mwachitsanzo, chiyambi cha valve).
