1.Flow–Yerekeza ku bunini cyangwa uburemere bwamazi yatanzwe napompe y'amazikumwanya umwe.Bigaragazwa na Q, ibice bisanzwe bikoreshwa mubipimo ni m3 / h, m3 / s cyangwa L / s, t / h.
2.Head–Bivuga imbaraga ziyongereye zo gutwara amazi hamwe nuburemere bwikibice kuva mumbere kugera kumasoko ya pompe yamazi, ni ukuvuga ingufu zabonetse nyuma yamazi hamwe nuburemere bwibice byanyuze muri pompe yamazi. Byerekanwe na h, igice ni Nm / N, gisanzwe kigaragazwa nuburebure bwinkingi yamazi aho pompi; Ubwubatsi rimwe na rimwe bugaragazwa nigitutu cyikirere, kandi amategeko yemewe ni kPa cyangwa MPa.
(Inyandiko: Igice: m/p = ρ gh)
Ukurikije ibisobanuro:
H = E.d-Es
Ed-Ingufu kuri buri buremere bwamazi kumazi asohoka ya flange yapompe y'amazi;
Es-Ingufu kuri buri buremere bwamazi kuri inlet flange ya pompe yamazi.
Ed=Z d + P d/ ρg + V2d / 2g
Es=Z s+ Ps / ρg + V.2s / 2g
Mubisanzwe, umutwe uri ku cyapa cya pompe ugomba gushiramo ibice bibiri bikurikira. Igice kimwe nuburebure bwapimwe bwumutwe, ni ukuvuga uburebure buhagaritse kuva hejuru yamazi yikidendezi cyinjira kugeza hejuru y’amazi ya pisine. Azwi nkumutwe nyirizina, igice cyacyo ni igihombo cyo guhangana ninzira iyo amazi anyuze mumuyoboro, mugihe rero uhisemo umutwe wa pompe, bigomba kuba igiteranyo cyumutwe nyirizina no gutakaza umutwe, nibyo:
Urugero rwo kubara pompe kubara
Niba ushaka gutanga amazi munzu ndende, tuvuge ko amazi ya pompe ari 50m3/ h, n'uburebure buhagaritse kuva hejuru y’amazi y’ikidendezi cyinjira kugeza ku rwego rwo hejuru rw’amazi yatanzwe ni 54m, uburebure bwuzuye bwumuyoboro w’amazi ni 150m, diameter ya pipe ni F80mm, hamwe na valve imwe yo hepfo, valve imwe y irembo na valve imwe idasubira inyuma, na umunani 900 yunamye hamwe na r / d = z, umutwe wa pompe ni bangahe kugirango wuzuze ibisabwa?
Igisubizo:
Duhereye ku ntangiriro yavuzwe haruguru, tuzi ko umutwe wa pompe ari:
H =Hnyabyo +H. igihombo
Aho: H nuburebure buhagaritse kuva hejuru yamazi yikigega cyinjira kugeza kurwego rwo hejuru rwamazi, ni: Hnyabyo= 54m
Higihomboni ubwoko bwose bwigihombo mumuyoboro, ubarwa kuburyo bukurikira:
Umuyoboro uzwi cyane wo kuvoma no kuvoma, inkokora, indangantego, indangagaciro zidasubira inyuma, indiba zo hepfo hamwe nizindi diameter zifite imiyoboro ni 80mm, bityo agace kayo kambukiranya ni:
Iyo igipimo cyo gutemba ari m 503/ h (0.0139 m3/ s), igipimo mpuzandengo kijyanye ni:
Igihombo cyo guhangana na diameter H, nkuko amakuru abivuga, iyo umuvuduko w’amazi ari 2,76 m / s, gutakaza metero 100 umuyoboro wibyuma byangiritse gato ni m 13.1, bikaba bikenewe uyu mushinga wo gutanga amazi.
Gutakaza imiyoboro y'amazi, inkokora, valve, kugenzura valve na valve yo hepfo ni2.65m.
Umuvuduko wumuvuduko wo gusohora amazi muri nozzle:
Kubwibyo, umutwe wose H wa pompe ni
H umutwe= H. nyabyo + H igihombo cyose=54+19.65 + 2.65+0.388 = 76.692 (m)
Iyo uhisemo amazi maremare yo gutanga, pompe itanga amazi ifite umuvuduko utari munsi ya 50m3/ h n'umutwe utari munsi ya 77 (m) ugomba guhitamo.
