Intangiriro kumagambo asanzwe (1) - Igipimo cyurugendo + ingero

1.Flow-Ibike byijwi cyangwa uburemere bwamazi yatanzwe napompe y'amaziKuri buri gihe. Reba kuri Q, ibice bikunze gukoreshwa byo gupima ni M3 / H, M3 / s cyangwa l / s / H.

2.-Niba bivuga imbaraga zo kwiyongera zo gutwara amazi hamwe na rukuruzi iva muri urubuga rwa pompe y'amazi, ni ukuvuga, ingufu zabonetse nyuma y'amazi anyura mu gihimbano. Byagaragajwe na H, igice ni NM / N, kirimo ubusanzwe kigaragazwa nuburebure bwinkingi y'amazi aho amazi yashyizwe kuvoma; Engineering rimwe na rimwe igaragazwa nigitutu cyikirere, kandi ishami ryemewe ni KPA cyangwa MPA.

 (Inyandiko: Igice: M./p = ρ gh)

Ukurikije ibisobanuro:

H = e_d-E_s

E_d-Energy kuri fagitire yamazi kumashanyarazi ya flange yapompe y'amazi;

Es-imbaraga kuri uburemere bwibice byamazi kuri inlet flange ya pompe y'amazi.

E_d=Z _d + P _d/ ρg + V²_d / 2G

E_s=Z _s+ P_s / ρg + v²_s / 2G

Mubisanzwe, umutwe ku izina rya pompe ugomba gushyiramo ibice bibiri bikurikira. Igice kimwe ni uburebure bwapimwe, ni ukuvuga uburebure buhagaritse buva hejuru yamazi ya pisine hejuru yubuso bwa pisine. Bizwi nkumutwe nyirizina, igice cyacyo ni igihombo cyo kurwanya inzira iyo amazi anyura mumuyoboro, niyo ahitamo umutwe wa pompe, agomba kuba igiterane cyukuri, ni:

Urugero rwumutwe wa pompe

Niba ushaka gutanga amazi ku nyubako ndende, tuvuge ko amazi ariho agenga pompe afite imyaka 50m³/ H, n'uburebure buhagaritse mu mazi ya pisine yo gufata amazi menshi ni 54m, umuyoboro umwe wo hasi, umuyoboro umwe wo hasi, umutware umwe wanditse hamwe na RFUT guhura n'ibisabwa?

Igisubizo:

Kuva ku ntangiriro hejuru, tuzi ko umutwe wa pompe ari:

H =H_ukuri +H _igihombo

Aho: h nuburebure buhagaritse buva hejuru yamazi yikigega cyinjira mumazi yamazi menshi, ni: h_ukuri= 54m

H_igihomboUbwoko bwose bwigihombo muri pipeline, bubarwa kuburyo bukurikira:

Kumenyekana na Pination Imiyoboro, Inzara, Indangagaciro, Impano zidasubizwa, Imyanya yo hasi hamwe nizindi diperayi ni 80mm, bityo agace kambukiranya igice ni:

Iyo igipimo cyurugendo gifite m 50 m³/ h (0.0139 m³/ s), igipimo cyimpuzandengo cyurugendo ni:

Igihombo cyo Kurwanya Kuruhande rwa Diameter H, ukurikije amakuru, mugihe igipimo cyuzuye cyamazi ari 2.76 m, gutakaza metero 100 ya metero 100

Gutakaza umuyoboro wa drain, inkokora, valve, reba valve na valve yo hepfo ni2.65m.

Umuvuduko Umutwe wo Kuraho amazi kuva nozzle:

Kubwibyo, umutwe wose h of pompe ni

H _Umutwe= H _ukuri + H _{igihombo cyose}=54+19.65 + 2.65+0.388 = 76,692 (m)

Mugihe uhitamo amazi menshi, pompe yo gutanga amazi hamwe no gutemba ntabwo ari munsi ya 50m³/ H n'umutwe utari munsi ya 77 (m) ugomba gutoranywa.
