Amanzi esatsiba Venturi: imigaqo esebenza, inkcazo, ukusetyenziswa

Uluhlu lwemibhobho iinjongo ezahlukeneyo kufuneka nakanjani babe units zeteknoloji, apho imilinganiselo yenziwa bume iinkonzo. Oku kusebenza imibhobho yamanzi eqhelekileyo, kunye nezibonelelo igesi, kwaye kananjalo ukuba izakhiwo ezizodwa mveliso, ukusebenza kunye nolwelo lwekhemikhali okhethekileyo. Kuzo zonke iimeko, iteknoloji inikezela ezizodwa izixhobo kwiisekethe flowmeters. Omnye enomtsalane kakhulu ngokwembono nokwenza izinto loo nezixhobo zomsebenzi umlomo venturi ufakwa ingongoma ethile yokulinganisa. Eli candelo ineendlela ezininzi, kodwa ukusetyenziswa bokuqonda ukuba ingqalelo xa ukhetha i modeli ithile.

ulwazi jikelele kwi amanzi esatsiba

Umsebenzi ophambili esatsiba - yimeko-bume womlinganiselo lo tiendlekela amanzi ekujoliswe kulo. Xa olu ukuziqhelanisa phawu ayikho kangako ithuba ukunxibelelana ulwelo ezahlukeneyo kwimihlaba yabo inzuzo noshowo. Inyaniso yokuba amanzi esatsiba okanye venturi, uyakwazi ukugcina ngereyithi ngokupheleleyo uxinzelelo ngexesha sicatshulwa medium. Okt licuthe emjelweni, Kakade ke, ifuthe kule parameter, kodwa hayi kakhulu njengoko kunjalo kunye namanye iindidi flowmeters.

Kukho nenye inkalo ebalulekileyo. Into yokuba umgangatho yokugqitha imilinganiselo umthamo wamanzi badla abachatshazelwa ubukhulu channel nto leyo kakhulu sokulinganisa isixhobo ingumthombo medium. Ukusebenza, venturi phantse ayitshintshi ukuchaneka zomlinganiselo kuxhomekeka parameters channel.

device

Esi sisixhobo esincinane ngohlobo ngemibhobho, apho izixhobo ubonelela kwiisayithi zobugcisa, eyenzelwe ukwenza imisebenzi yokulinganisa. Ngokuqhelekileyo, embindini, ngamanye inxalenye usembindini esatsiba, eligaqa ukuyiqinisa ukusuka apho elinye icala oluya egumbini ekhethekileyo yolinganiso kunye Umqala uxinzelelo otyiwa. Kwelinye icala ifomu ityhubhu le iguqulelwa ikhowuni kwaye yenza intamo. Nantsi i mingxuma ezimbalwa uxinzelelo yokukhetha, ngokunjalo diffuser. Ngokuqhelekileyo, impompo jet elidityaniswe kuyo kweli cala nokuba ngqo okanye ngokusebenzisa izixhobo ezikhethekileyo zococeko.

Phakathi iingenelo noshowo oku lweengcali mveliso inqaku kunye ukusebenza kwiimeko emxinwa yalo mbhobho. Noko ke, kukho plus ebalulekileyo yabaculi bangenamava. Yena imodeli lula ufakelo umlomo.

wenza njani le venturi?

Icebo yathiywa emva sisazinzulu Italian ngenxa yokuba iye wavula isiphumo zokucutha, xa ulwelo ukusebenza udlula isahlulo iingqameko. Kungenxa kule mgaqo, zincediswa yi ngomthetho Bernoulli, yokusebenza iityhubhu ezinjalo. Xa practice oku kuthetha ukuba ulwelo Kudlula isahlulo iingqameko, apho kukho indawana ekhethekile xi yokhetho thunzi, apho kubonelelwa kunye umlomo venturi. Umgaqo ukusebenza ikwabandakanya intsebenziswano lamajelo obhobhozayo izixhobo umlinganiselo ngqo. Kuba umlinganiselo echanileyo, ingakumbi ingcinezelo isicelo gauge, leyo angamelwa ngohlobo sixhobo analog kunye digital device.

iimpawu

Owona bemfuno zokukhethwa ngale mibhobho - enobubanzi isici. Le fomati kunayo yonke sele kuluhlu ukusuka mm-6 ukuya ku-12. Kukho kwakhona ubungakanani ezinkulu, apho kufuneka bachongwe ukuba umbhobho ethile. Kuyenzeka ukuba ukusebenzisa amaqhoshana kunye nobukhulu olululo utshintsho ngoko engqongqo ngaphantsi umlomo ezithile ayibalulekanga kangaka. Koko ubukhulu zizixhobo ebaluleke kakhulu leyo senziwe venturi okanye wekhadi mbobo e ezintsonkothileyo jikelele. Ngokuqhelekileyo kusetyenziswa njengesiseko engatyiwa okanye carbon zentsimbi. Nakuba kunjalo, iimpawu zokusebenza zokhuseleko kuxhomekeka kuhlobo ukutyabeka. Iingcali Siyaleza ukuqinisekisa ihlala ukusingatha imifuziselo wayesebenzisa iphathwa okanye primer elikhusela, phakathi kwezinye izinto, kwaye isifo imichiza. Ukuba sithetha ukufakelwa kwi imiphantsi industrial, simse ngokwemiqathango kukuthembeka iya kuba dip eshushu nokwaleka kwalenza.

uhlobo

Umahluko omkhulu nenesakhiwo ngengqiqo yokuba ezinye ubuchwepheshe abe design okhethekileyo. Umzekelo, uhlobo efanayo imilomo, apho zinika isixa ongangokugibisela Taper ngaphandle unyango. Le modeli zenziwa ngenaliti nokusetyenziswa matrix nesanti ezizodwa kunye nokusebenza ubuze iindawo zokuphuma amagophe ezinyongeni kunye entanyeni kuphela. iinguqulelo kakhulu nzima Akayomizekelo olunikezela igalelo kunye pre-processing sites, leyo basebenzisane nempompo jet i kwiinguqulelo ezahlukeneyo. Kulo mzekelo isiseko engundoqo inokwenziwa ngaphandle kokuba kuqhutyelwe okhethekileyo.

Umahluko Inqununu ukusuka iintlobo ngasentla nto yenziwa ngenaliti kunye indlela yokwenza iwelding. Kulo mzekelo, isahlulo tapered ziya kuphunyezwa kumgca othe tye, kwaye enembonakalo ajikelezayo.

Fields of application

iimpawu zezakhiwo ngenxa zombini iindlela ezingaqhelekanga of nemilomo yesicelo. Ngokukodwa, kugunyaziso ngokutsha olu hlobo sele isicelo iiyunithi isitofu apho kusebenza kunye iimpompo jet utshilo. iindlela ezifana zisetyenziselwa ngokuveza imixube zerhasi umphunga elulwelo, kwakunye yokuthumela kubo iindawo ubunzima obungakumbi. Ayikwazi ukwenza ngaphandle nkqubo umlomo negesi zokucoca, kwezinye iinguqulelo. Ngokomzekelo, amanzi esatsiba kufakwa ngesantya scrubber leyo okucoca umxube inkonzo ye micron kunye submicron amasuntswana. Izixhobo yale hlobo ezisetyenziswa kwezinye boilers thermal kunye umphunga, kodwa advantageously ukusuka kwinqanaba mveliso.

Iingenelo neengozi esatsiba venturi

Izinto eziluncedo ukuqina kwemithambo osebenza isiphumo Venturi, kunganxulunyaniswa kwi indlela yokufakela iindawo ezishiyanayo parameters lamajelo feed. Noko ke, ukuze bakwazi ukulisebenzisa ngokupheleleyo eli thuba kufuneka alungiselele ekuqaleni kunye ezisebenza ngokubakho ezifanelekileyo. Umzekelo, ukuba venturi esatsiba ekhethiweyo kwisikhululo sokumpompa ukusebenza ngamaxesha ezahlukeneyo, ngokuxhomekeke kwiimfuno hydraulic kunokwahluka umthamo yokumpompoza fluid - ngokulandelelana, zilungiswe sentlalo nomthombo feed.

Njengokuba kubakho iingxaki, baye bancipha ubu ukusetyenziswa kwemibhobho ezingenazo i ezikumgangatho ophezulu nokwaleka olukhuselayo. Kwelinye icala, imodeli kunye ubukho unyango kumphezulu mihla ayabiza kakhulu ngakumbi.

isiphelo

imibhobho umendo Modern kukhatshwa izikhululo zokumpompa bethatha kudluliselwa izixhobo automated esweni nokulawula kunye nokuqaliswa iibhodi elektroniki. In ezisebenzayo ezinye parameters yabaqhubi esweni kunye zokukala nezixhobo.

Mhlawumbi esatsiba venturi yi enye yamacebo abambalwa eklasini yayo, apho ukusebenza kusekelwe kumgaqo ebonakalayo yolawulo. Technique ukuhlanganiswa amanqaku kubume igiza ikwabangela ukuchaneka womlinganiselo kunye nefuthe elibi incinane ukusebenza kwemijelo engundoqo. Enye into kukuba ukuze alondoloze lusebenze ifuna ukulungiswa rhoqo leeyunithi yokulinganisa.
