IYIphampu ye-centrifugal evundlile yesiteji esisodwa

incazelo yomkhiqizo

1. Iphampu yohlobo lwe-IS iyiphampu ye-centrifugal enesiteji esisodwa, eklanywe ngokuvumelana nezinga lamazwe ngamazwe le-ISO2858.Iwumkhiqizo oshintshwayo wamaphampu amanzi ohlobo luka-B no-BA.Ilungele ukuhlinzekwa kwamanzi ezimbonini nasemadolobheni kanye ne-drainage, futhi ingasetshenziselwa ukuchelela ngenkasa kwezolimo kanye nokukhipha amanzi.Isetshenziselwa ukuthutha amanzi acwebile, olunye uketshezi olunezakhiwo ezibonakalayo nezimbali ezifana namanzi acwebile, futhi izinga lokushisa alidluli ku-80°C.

Uhlobo lwe-ISR luwuchungechunge lwamaphampu amanzi ashisayo aklanywe inkampani yethu ngokuya ngokusebenza nosayizi oshiwo kuzinga lamazwe ngamazwe le-ISO2858.Ilungele ukuhlinzekwa kwamanzi kuma-boilers wamanzi ashisayo, izinhlelo zokujikeleza kwamanzi ashisayo, futhi ingasetshenziselwa ukuhlinzekwa kwamanzi ezimbonini nasemadolobheni, i-drainage kanye nokunisela, kodwa izinga lokushisa alidluli ku-l50 ℃.

2. IS(R) ibanga lokusebenza (ngokuya ngephoyinti lokuklama):

Isivinini: 2900r/min kanye ne-1450r/min

Ububanzi bokungena: 50-200mm

Ukugeleza: 6.3-400 m³/h

IS: 80-65-160 A... J (no-D)

I-Yang Cheng: 5-125m

4. Ukukhethwa kwephampu:

(1)Lapho ekhetha imininingwane yephampu yamanzi, umsebenzisi kufanele anake la maphuzu alandelayo: (1) Izinga lokugeleza kwephampu yamanzi ekhethiwe kufanele libe ngaphansi kokukhiqizwa kwamanzi okujwayelekile komthombo noma eminye imithombo yamanzi;

(2)Inhloko yephampu yamanzi kufanele ikhethwe ngokwekhanda langempela, futhi ukulahleka kwepayipi lephampu yamanzi kufanele kubhekwe.

(3)Uma kukhethwa iphampu yamanzi, izinga lokushisa loketshezi oludlulisayo kufanele licatshangelwe, okufanele libe ngaphansi kwezinga lokushisa elishiwo.

(4) Lapho kukhethwa iphampu yamanzi, ubude bokufakwa kwephampu yamanzi kufanele bucatshangelwe, okungukuthi, ibanga eliqondile ukusuka endaweni emuncwa uketshezi ukuya eksisi yepompo lamanzi kufanele libe ngaphansi kunobude obushiwo bepompo yamanzi. :

Isilinganiso sobude bokufakwa kwephampu Hsz:

Hsz≤Hv-Fv-△Hs-[NPSH]

Hsz≤10.09-△Hs-[NPSH]

Kuphi: Hv=10.33 (m) umfutho ojwayelekile womkhathi.(ikholomu yamanzi)

Fv=0.24 (m) Ingcindezi yokuhwamuka kwamanzi okushisa avamile (20°C) (ikholomu yamanzi)

△Hs=Ukulahleka kwepayipi lokudonsa, kubalwa ngokuya ngesimo sangempela.

[NPSH] = i-NPSH evumelekile.

[NPSH]=[NPSH]r+0.3(m)

[NPSH]=I-NPSH edingekayo inikezwe Eshidini Ledatha Yokusebenza
