Pampu Ikayamba, Kodi Titseke Vavu Yotulukira Kapena Ayi?

Ambiri, kuyambapompa centrifugal, malinga ndi ndondomeko ayenera kukhala, choyamba mpope chipinda chodzaza sing'anga, kutseka valavu, ndiyeno kutsegulampope, cholinga chake ndi: kumbali imodzi kuteteza chiyambi cha panopa ndi kuwonongeka kwakukulu kwa galimoto;Komano, kupewa yomweyo imfa ya mavuto pambuyo poyambirampope, kutsatira mumpopecavitation.Koma mavuto ambiri sanganenedwe onse!

Kwa otsika otsika ndi otsika mutumapampu, kutseka kapena kusatseka valve yotuluka si vuto.

Kwa wamkulumapampu, chotulukapo nthawi zambiri chimatsegulidwa pang'ono kuti chiteteze kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valve pambuyo poyambira, ndipo valavu yotulutsira sivuta kutsegula, kotero kutsegula kwa valve kumatsegulidwa pang'ono.

Enamapampu centrifugalidzatsegula pang'ono valavu yotulutsira chifukwa cha kutentha ndi zofunikira zina.

Ngati ndi kuyamwa, kuti mutseke valavu yotuluka, ndiyeno mutsegule valavu (osati pampu yodzipangira nokha), komanso mutsegule valve yotulutsa mpope.

Pazinthu zina zapadera, valavu yotulutsira singatsegulidwe, mwachitsanzo, propylene yamadzimadzi, ngati valavu yotulutsira imatsegulidwa, propylene imatuluka, mpope sungathe kukakamiza, choncho iyenera kutsekedwa poyamba, kupopera ndi kupopera. kenako tsegulani valavu yotulutsa mwachangu.

Pamwambapa ndi mapampu centrifugal.Kwa mitundu ina ya mapampu, zinthu zili motere:

1. Makhalidwe oyambira otaya kwambiri a pampu ya axial otaya ma valve otseguka kwathunthu

Mphamvu ya shaft ya axial flowmpopeNdilo lalikulu kwambiri pamayendedwe a zero, omwe ndi 140% ~ 200% ya mphamvu ya shaft yovotera, ndipo mphamvu ndiyochepa kwambiri pamayendedwe othamanga kwambiri.Choncho, kuti muchepetse kuyambika kwamakono, zizindikiro zoyambira za shaft ziyenera kukhala zoyambira kwambiri (ie, chiyambi cha valve yotseguka).

2. Makhalidwe oyambira a pampu osakanikirana-othamanga-otsegula bwino ma valve oyambira

Mphamvu ya shaft yosakanikiranampopepa ziro flow condition ili pakati pa ziwirizimapampu, yomwe ndi 100% ~ 130% ya mphamvu zovoteledwa.Choncho, makhalidwe oyambira a pampu yosakanikirana ayeneranso kukhala pakati pa ziwirizimapampu, ndipo ndi bwino kuyamba ndi kutsegula valavu kwathunthu.

3. Makhalidwe oyambira a pampu ya vortex-yotsegula kwathunthu valavu

Mphamvu ya shaft ya vortexmpopeNdilo lalikulu kwambiri pamayendedwe a zero, omwe ndi 130% ~ 190% ya mphamvu yovotera shaft.Choncho, mofanana ndi kutuluka kwa axialmpope, zizindikiro zoyambira pampu ya vortex ziyenera kukhala zoyambira kwambiri (ndiko kuti, kuyambika kwa valve).
