Musoro, kuyerera uye simba zvakakosha paramita yekuongorora mashandiro epombi:

1.Flow rate

Kuyerera kwepombi kunonziwo vhoriyamu yekuunza mvura.

Inoreva huwandu hwemvura inounzwa nepombi panguva yeyuniti. Inomiririrwa nechiratidzo Q, chikwata chayo iita / yechipiri, cubic mita / yechipiri, cubic mita / awa.

2.Musoro

Musoro wepombi unoreva kureba uko pombi inogona kupomba mvura, kazhinji inomiririrwa nechiratidzo H, uye chikwata chayo mita.

Musoro we pombi yekuyamwa kaviri yakavakirwa pamutsara wepakati we impeller uye ine zvikamu zviviri. Kureba kwakadzika kubva pakati pepombi impeller kusvika kumvura pamusoro pemvura, kureva, kureba uko pombi inogona kusveta mvura, inonzi suction lift, inonzi suction lift; kureba kwakatwasuka kubva pakati pepombi impeller kusvika pamvura padziva rekubuda, ndiko kuti, pombi yemvura inogona kudzvanya mvura ichikwira Kureba kunonzi kudzvanywa kwemvura musoro, kunonzi kudzvinyirirwa sitiroko. Kureva, pombi yemvura musoro = mvura yekusveta musoro + musoro wemvura. Zvinofanira kutaurirwa kuti musoro wakanyorwa pazita rezita unoreva musoro unogona kubudiswa nepombi yemvura pachayo, uye haisanganisi musoro wakarasika unokonzerwa nekupokana kwepombi yekuyerera kwemvura. Paunosarudza pombi yemvura, chenjerera kuti urege kuifuratira. Zvikasadaro, mvura haizopombi.

3. Simba

Huwandu hwebasa rinoitwa nemuchina panguva yeyuniti inonzi simba.

Inowanzomiririrwa nechiratidzo N. Inowanzo shandiswa zvikamu ndezvi: kilogram m / s, kilowatt, horsepower. Kazhinji simba remagetsi emagetsi emagetsi rinoratidzwa mu kilowatts; iyo simba unit yeinjini yedhiziri kana peturu injini inoratidzirwa musimba rebhiza. Simba rinofambiswa nemuchina wemagetsi kune pombi shaft inonzi shaft simba, iyo inogona kunzwisiswa sesimba rekupinza repombi. Kazhinji kutaura, simba repombi rinoreva shaft simba. Nekuda kwekupokana kwekupokana kwekutakura uye kurongedza; kukweshana kuri pakati pechipfuro nemvura painotenderera; iyo vortex yekuyerera kwemvura mupombi, gap backflow, pekupinda nekubuda, nekukanganisa kwemuromo, etc. Inofanirwa kupedza chikamu chesimba, saka pombi haigone kushandura zvachose simba rekupinza remuchina wemagetsi kuita. simba rinoshanda, uye panofanira kuva nekurasikirwa kwesimba, kureva kuti, chiyero chesimba rinoshanda repombi uye kurasikirwa kwesimba mupombi ndiyo shaft simba repombi.

Pombi musoro, kuyerera kuverenga formula:

Musoro wepombi H=32 unorevei?

Musoro H=32 zvinoreva kuti muchina uyu unogona kusimudza mvura kusvika pamamita makumi matatu nemaviri

Kuyerera = kuyambuka-chikamu nharaunda * kuyerera velocity Iko kuyerera kwevelocity inoda kuyerwa wega: stopwatch.

Pombi inosimudza fungidziro:

Musoro wepombi hauna chokuita nesimba, inobatana nehupamhi hwepombi yepombi uye nhamba yematanho emagetsi. Pombi ine simba rimwechete inogona kunge iine musoro wemazana emamita, asi kuyerera kunogona kunge kuine mashoma masikweya metres, kana musoro ungangoita mashoma metres, asi kuyerera kungasvika 100 metres. Mazana enzira. Mutemo mukuru ndewekuti pasi pesimba rimwechete, kuyerera kwemusoro wepamusoro kuduku, uye kuyerera kwemusoro wakaderera kwakakura. Iko hakuna yakajairwa calculation formula yekuona musoro, uye zvinoenderana nemamiriro ako ekushandisa uye modhi yepombi kubva kufekitori. Inogona kuverengerwa zvichienderana nepombi yekubuda kudzvinyirira gauge. Kana pombi yekubuda nayo iri 1MPa (10kg/cm2), musoro ungaita 100 metres, asi simba rekusveta rinofanirwa kutariswa zvakare. Papombi yecentrifugal, ine misoro mitatu: musoro chaiwo wekusveta, musoro chaiwo wekumanikidza mvura uye musoro chaiwo. Kana zvisina kutaurwa, zvinotendwa kuti musoro unoreva musiyano wehurefu pakati penzvimbo mbiri dzemvura.

Zvatiri kutaura nezvazvo pano ndiko kuumbwa kwekupokana kweiyo yakavharwa air conditioning mvura inotonhora system, nekuti iyi system inowanzoshandiswa system.

Muenzaniso: Kufungidzira musoro wepombi yekuyamwa kaviri

Maererano nezviri pamusoro apa, kurasikirwa kwekumanikidzwa kwemhepo-inogadzirisa mvura system yeimba yakakwirira-inokwira inenge 100m yakakwirira inogona kufungidzirwa, kureva, kusimudza kunodiwa nepombi yemvura inotenderera:

1. Chiller resistance: tora 80 kPa (8m mvura column);

2. Kupokana kwepombi: Tora kupikisa kwemudziyo wekusvibisa, muunganidzi wemvura, separator yemvura uye pombi muimba yefiriji se50 kPa; tora kureba kwepombi padivi rekutapurirana uye kugovera se300m uye yakananga frictional resistance ye200 Pa/m, ipapo The friction resistance is 300*200=60000 Pa=60 kPa; kana kushorwa kwenzvimbo padivi rekutapurirana uye kugovera kuri 50% yekupokana kwekupokana, kushorwa kwenzvimbo ndeye 60 kPa * 0.5 = 30 kPa; kupikisa kwese kwepombi yehurongwa ndeye 50 kPa+ 60 kPa+30 kPa = 140 kPa (14m mvura column);

3. Kurwisana kwemhepo inogadzirisa mhepo inogadzirisa mudziyo: kushorwa kweiyo yakasanganiswa air conditioner kazhinji yakakura kudarika iyo fan coil unit, saka kushorwa kweiyo yekare ndeye 45 kPa (4.5 mvura column); 4. Kurwisana kwevhavha yekudzivirira nzira mbiri: 40 kPa (0.4 mvura column) .

5. Nokudaro, chiyero chekupikisa kwechikamu chimwe nechimwe chemvura ndeye: 80 kPa + 140kPa + 45 kPa + 40 kPa = 305 kPa (30.5m mvura column)

6. Kaviri kusveta musoro wepombi: Kutora chikamu chekuchengetedza che10%, musoro H = 30.5m * 1.1 = 33.55m.

Zvinoenderana nemhedzisiro yefungidziro iri pamusoro, kupererwa kwesimba kweiyo air-conditioning mvura system yezvivakwa zvechiyero chakafanana inogona kubatwa zvakanyanya. Kunyanya, inofanira kudziviswa kuti kurasikirwa kwekumanikidzwa kwegadziriro yakakura zvikuru nekuda kwekufungidzira kusingaverengeki uye kwakanyanyisa kuchengetedza, uye musoro wepombi yemvura inosarudzwa zvikuru. Zvichikonzera kupera kwesimba.
