Nhanganyaya kune yakajairika Pump Termy (1) - kuyerera riini + mienzaniso

1.Flow-Zviyo kune vhoriyamu kana uremu hwemvura yakapihwa nePombi yemvuraPer Yuniti nguva.Ochiremba naQ, iyo inowanzoshandiswa zvikamu zveyero ndeye M3 / H, m3 / s kana s, t / s, t / s, t / s, t / s, t ..

2.head-Inoreva kune yakawedzera simba rekutakura mvura neyunivhesiti kubva kuIntlet kune iyo Pombi yemvura, ndiko kuti, iyo simba rakawanikwa mushure memvura neyunivhesiti inopfuura nepombi yemvura. Inoratidzwa neH, iyo unit ndeye NM / N, iyo inotaurwa neyakajairika nekureba kwekamuri yemvura uko mvura yakamiswa; Injiniya dzimwe nguva inoratidzwa neyekumanikidzwa kwemweya, uye chikamu chepamutemo chiri kpa kana mpa.

 (Zvinyorwa: Unit: m/p = ρ gh)

Maererano nerondedzero:

H = e_d-E_s

E_d-Energy pachikamu chetiremu chemvura pakubuda kwekunze kwePombi yemvura;

Es-simba pane unit uremu hwemvura kuInle Flange yePombi yemvura.

E_d=Z _d + P _d/ ρg + V²_d / 2G

E_s=Z _s+ P_s / ρg + v²_s / 2G

Kazhinji, musoro uri pachirevo chebomba chinofanira kusanganisira zvikamu zviviri zvinotevera. Chimwe chikamu ndechekuyera musoro kumusoro, ndiko kuti, kukwirira kwakamira kubva kumusoro kwemvura kweiyo inlet puru kune mvura yemvura yedziva rekunze. Inozivikanwa semusoro chaiwo, chikamu charo kurasikirwa munzira kana mvura ichipfuura nepombi, saka kana ichisarudza musoro wepombi, iyo chaiyo yemusoro uye yekurasikirwa nemusoro, ndiko kuti:

Muenzaniso wePombi Pamplation Kuverenga

Kana iwe uchida kugovera mvura kune yakakwira-yekukwira kuvaka, ngatitii iyo yazvino mvura inopihwa pombi iri 50m³/ h, uye kukwirira kwemvura kubva kumusoro kwemvura yedare rekutakura mvura iri 54M

Mhinduro:

Kubva pasumo pamusoro, tinoziva kuti pombi musoro ndeye:

H =H_chaiko +H _kurasikirwa

Iko: H ndiko kukwirira kwemvura kubva kumvura yemvura yeiyo inlet tank kune yakanyanya kuendesa mvura yemvura, iyo iri: H_chaiko= 54m

H_kurasikirwaMhando dzese dzekurasikirwa mune pombi, iyo inoverengwa seinotevera:

Zviitiko zvinozivikanwa uye zvidhori zvezvidimbu, ndege dzemukati, mavharuvhu, dzisiri-dzidzo dzevharuvhu, pasi pombi

Kana chiyero chinoyerera chiri makumi mashanu m³/ h (0.0139 m³/ s), iyo yakaenzana average kuyerera chiyero ndeye:

Kurasikirwa kwekudzivisa pamwe ne data h, maererano nedata, apo iyo yekuyerera mwero ndeye 2.76 m / s, kurasikirwa kwemakumi mamirimita mita ndeye 13.1 m, inodiwa yeiyi chirongwa chemvura.

Kurasikirwa kweDrain pombi, elbow, vharuvhu, tarisa vharuvhu uye pasi pevhu2.65m.

Velocity musoro wekurasa mvura kubva ku nozzle:

Saka, iyo yakazara musoro h ye pombi iri

H _musoro= H _chaiko + H _{Kurasikirwa Kwese}=54+19.65 + 2.65+0.388 = 76.692 (m)

Kana uchisarudza yakakwira-mvura yekupa mvura, iyo mvura yekupa pombi ine kuyerera isingasviki 50m³/ h uye musoro kwete pasi pe77 (m) inofanira kusarudzwa.
