Muchitsauko chakapfuura chakaratidzwa kuti mamiriro ekunze ezvemasvomhu emasimba anoshandiswa nemvura pakuzorora aigona kuwanikwa nyore. Izvi zvinodaro nekuti muHydrostatic chete mauto ekudzvinyirira anobatanidzwa. Kana iyo mvura mukufamba ichinzi, dambudziko rekuongorora kamwechete rakanyanya kuoma. Haisi chete iyo yehukuru hweVelocity yehukuru uye kutungamirirwa kunofanirwa kuitirwa, asi kune zvakare pesvedzero yakaoma ye viscosity inokonzeresa svutugadzike kana kushushikana pakati pekufambisa kwemvura zvidimbu uye kune iyo ine miganhu ine miganhu. Iyo hama inofamba inokwanisika pakati pezvisikwa zvakasiyana-siyana zveviri muviri inokonzera kudzvinyirira uye sheare kushushikana zvakanyanya kubva kune imwe nzira kune imwe maererano nemamiriro ezvinhu anoyerera. Nekuda kwekunetseka kwakabatana neyekupedzisira phenomenon, kunyatsoongorora kwemasvomhu kunongoitika mune zvishoma, uye kubva kune izvo zvisingabvumirani, zviitiko zvine simba, kana nekuedza kufungidzira, kana nekufunga kurerutsa kuti uwane mhinduro yekutsanangura. Mashandiro maviri aya haasarudzika, sezvo mitemo yakakosha yemamita inogara ichishanda uye inogonesa nzira dzekunzwisisa kuti dziratidzwe munzvimbo dzinoverengeka dzinokosha. Zvakare zvakakosha kuti uzive zvakanaka huwandu hwekutsauka kubva kumamiriro ezvinhu echokwadi anoenderana nekuongororwa kwakareruka.
Iyo inowanzo kuve yakarerutsa fungidziro ndeyekuti iyo mvura yakanakira kana yakakwana, nokudaro kubvisa iyo inokanganisa viscous mhedzisiro. Uku ndiko kwehwaro hwenyika hydrodynamocs, bazi rezvemashematics masvomhu akagamuchira kutarisisa kubva kunhengo dzakakura kudaro seStoke, Rankine, Rankine, Kalvin uye Gwayana. Kune zvakadzama miganhu miviri yemasangano mune yekare dzidziso, asi semvura ine zvikwangwani zvakaderera, zvinozvibata semvura chaiyo mumamiriro mazhinji. Nechikonzero ichi, vekare hydrodynamics vanogona kutariswa seyakanyanya kukosha kumashure kune kudzidza kwehunhu hwehunhu hwekufamba kwemvura. Chitsauko chazvino chine chekuita nemhando yepamusoro yemhando yemvura uye inoshanda sekutanga kwenhamba yekubudirira zvitsauko kubata nematambudziko akanyanya kusangana neinjiniya hydrawuuls. Izvo zvitatu zvakakosha zvekutanga zvehunyanzvi hwemvura inonzi, kuenderera mberi, Bernoulli, uye mharidzo yekuwedzera inotorwa uye kukosha kwavo kwakatsanangurwa. Gare gare, miganhu yedzidziso yekare inofungidzirwa uye maitiro emvura chaiyo yakatsanangurwa.an isingaenderwiwi mvura inofungidzirwa kuti inofungidzirwa mukati mazviri.
Mhando dzekuyerera
Mhando dzakasiyana-siyana dzekufambisa dzemvura dzinogona kutaurwa seinotevera:
1.Trumblent uye Laminar
2.rotational uye kurwara
3.Stable uye isina kugadzikana
4.Uiform uye isina-yunifomu.
Mvs Series Axial-inoyerera Pumps Avs Series Yakasanganiswa-Flow Pumps Iyo nyowani yePumps 'kugona makumi maviri muzana yakakura kupfuura iyo yekare. Kubudirira ndeye 3 ~ 5% yakakwirira kupfuura yekare.

Aya mazwi anotsanangura maitiro emuviri ekuyerera.
Mukutambudzika kwechiedza, kufambira mberi kwezvinhu zvimedu zvinosanganisika uye pane zvinoita kunge zvisingaonekwe zvinoitika. Vhesi velocities kuti iyo kufamba ndeyekudzokera uye kutinhira kwete rectilinear. Kana dhayi ikarongedzwa pane imwe nzvimbo, inokurumidza kusimbisa murukova rwendo rwokuyerera. Panyaya yekuyerera kwemhirizhonga mupipi, semuenzaniso, kunyorera pakarepo kweValence pachikamu kwaizoratidza kugoverwa kwekugoverwa sezvakaratidzwa mumufananidzo 1 (a). Iyo yakasimba vhezheni, sezvingadai zvakanyorwa nezviridzwa zvakajairika, zvinoratidzwa muzvinyorwa zvebudiriro, uye zviri pachena kuti kuyerera kwemhirizhonga kunoratidzwa neyelticuctuating velocity yakatsemuka pane imwe nguva yakatenderera.

MuLaminar inoyerera zvese zvidimbu zvemvura zvinopfuurira pamwe nenzira yakafanana uye hapana chinhu chinotapudza chikamu cheVELELTHY. Kufambira mberi kwakarongeka kwakadaro kuti chikamu chega chega chinotevera chaizvo nzira yeiyo tarisiro yakatangira pasina kutsauka. Nekudaro tsvina yakatetepa yeDhayi icharamba yakadaro asi isina kusiyana. Iko kune yakakura kutapudza velocity gradient muLaminar kuyerera (Fig.1b) pane turbilent Foow.Relocity v uye iyo yakakwira Velocity v Max iri 0,5 neTurbulent kuyerera uye 0,05 neLaminar kuyerera.
Kuyerera kweLaminar kunosanganiswa ne lowoloes uye viscous slugghin Mitemo yemaresari kuyerera inonzwisiswa zvizere, uye nemamiriro ezvinhu akareruka mamiriro ekugoverwa velocity anogona kuongororwa mathematic. Nekuda kwekushomeka kwayo kusarongeka kwechisikigo

Izvo zvinonyanya kushandiswa kumoto mvura muPetrochemical, gasi rechisikigo, chirimwa chemagetsi, machira, wharf, mhizha, yekuvaka, yakakwirira-yekuvaka uye mamwe maindasitiri. Izvo zvinogona zvakare kushanda muchikepe, tangi regungwa, ngarava yemoto uye dzimwe nguva dzekutangisa.
Kutenderera uye kuridza kuyerera.
Kuyerera kunonzi kunotenderera kana yega yega fluid tulique ine angular velocity nezve yayo yakawanda nzvimbo.
Mufananidzo 2A unoratidza yakajairika velocity kugovaniswa yakabatana nekuyerera kwekuyerera kwakapfuura chikamu chakatwasuka. Nekuda kweiyo isina-yunifomu velocity kugoverwa, chidimbu chine axes ayo maviri pakutanga anoremadza ane dhigirii diki rekutenderera. Mufananidzo unoyerera
Nzira inoratidzwa, ine velocity zvakananga zvakabatana kune radius. Mataundi maviri ezvikamu zvetenderedzwa anotenderera nenzira imwechete kuti kuyerera kwatenderera zvakare.

Kuti ufambe kuve nehuremu, iyo velocity kugovera padhuze nepakati muganho wakananga unofanirwa kuve wakunifomu (Fig2b). Panyaya yekuyerera nenzira yakatenderera, inogona kuratidzwa kuti kuyerera kwekuyerera kunongoda kupihwa kuti vhezheni iri pachena kune iyo radius. Kubva pakutarisa kwekutanga kumufananidzo 3, izvi zvinoratidzika zvisirizvo, asi bvunzo dzinotyisa dzinoburitsa pachena kuti mademo maviri anotenderera mumativi akatarisana kuti agadzirise denderedzwa remazambuko iyo isina kuchinjika kubva kune yekutanga nyika.

Kutsiga uye kusasimba kuyerera.
Kuyerera kunonzi kuri kutsiga kana mamiriro ezvinhu panguva ipi neipi anogara achiremekedza nguva. Kududzirwa kwakasimba kwedudziro iyi kwaizotungamira kumhedziso yekuti kuyerera kwemhirizhonga hakuna kumbobvira kwakasimba. Nekudaro, nekuda kwechinangwa chazvino chakanakira kurangarira kuwanda kwemvura seyekuchinjika uye kuchinjika kunosangana neiyo nyonganiso ichingoita sekiseni chete. Muenzaniso uri pachena wekuyerera wakareruka rinogara richiraswa mumakuru kana rakavhurika chiteshi.
Sezvinoita corollary inoteedzera kuti kuyerera hakuna kugadzikana kana mamiriro ezvinhu akasiyanisa neruremekedzo nenguva. Muenzaniso wekuyerera unonetsekana kuyerera kwakasiyana muzinga kana chiteshi chakavhurika; Izvi zvinowanzoitika phenomomenon ichitevedzana, kana kuteverwa ne, kutsiga kwakasimba. Zvimwe kujairana
Mienzaniso yeimwe nguva yakanyanya kuitika ndeyekufamba kwekufamba uye iyo cyclic kufamba kwemiviri mikuru yemvura mune inoyerera kuyerera.
Mazhinji ematambudziko anoshanda muHydraulic engineering ane hanya nekuyerera kwakasimba. Iyi ine rombo rakanaka, kubva panguva inoshanduka mune isina kugadzikana kuyerera zvakanyanya kuongorora kuongororwa. Saizvozvo, muchitsauko chino, kufunga kwekuyerera kusingadzoreki kuchadzikiswa kune mashoma mashoma zviitiko. Izvo zvakakosha kuti uzive kuti zviitiko zvakati wandei zvekuyerera zvisina kugadzikana zvinogona kuderedzwa kusvika kune yakatsiga mamiriro nekuda kweiyo tsika yekufamba kwehama.
Saka, dambudziko rinosanganisira mudziyo unofamba uchiramba uchiramba uchiri kutsauswa kuitira kuti mudziyo unomira uye mvura iri kufamba; Chete chinongedzo chekufanana cheFluid maitiro ayo iyo hama yehukama ichave yakafanana. Zvakare, wave kufamba mumvura yakadzika inogona kuderedzwa kune iyo
State Strate nekufungidzira kuti mucherechedzi anofamba nemafungu ari pane imwe chete velocity.

Kuputa tembiricha pazasi 60 ° C, tumira kuve neyakagadzirwa zviyo (sekukanda simbi nesimbi uye nejecha rakanaka, etc.) yegungwa kana marara emvura.
Yunifomu uye isina-yunifomu kuyerera.
Kuyerera kwacho kunonzi kuve yunifomu kana pasina musiyano muhukuru uye kutungamirirwa kweiyo velocity vector kubva kune imwe nzira kuenda kune imwe munzira yekuyerera. Zvekuteerera neiyi tsanangudzo, iyo nzvimbo yeyedzo yekuyerera uye velocity inofanira kunge yakafanana pane ese mambakwedza. Kuyerera kusiri-yunifomu kunoitika kana velocity vector vanosiyana nenzvimbo, muenzaniso unowanzoyerera pakati pekushandura kana kutsauka miganhu.
Ose maviri emamwe mamiriro emamiriro ezvinhu anowanzoitika mukuvhurika Izvo zvinofanirwa kucherechedzwa kuti mamiriro anoenderana nenzvimbo kwete nguva uye saka mune zvakarongedzwa kuyerera (eg.papes pasi pekumanikidzwa), ivo vakazvimiririra vane tsika dzakasimba kana dzisina kutsiurwa.
