Uphononongo lovavanyo lwempompo yodaka lwaseChina kunye nesalathiso sexesha elizayo sokuphucula
Nge-PIV, iteknoloji ye-LDV kunye nobuchwepheshe be-ultrasonic buvuthwa, abantu banokuthatha ithuba lobu buchwepheshe obuphambili kwiimvavanyo ze-flow field ngaphandle kokuphazamiseka kwintsimi yokulinganisa okuchanekileyo.
Ezinye zezi teknoloji eziphambili ziye zafundwa kusetyenziswa i-china slurry pump pump flow field eCanada, sinokusebenzisa lo mba i-PIV (i-particle image velocimetry) iqhutywe isifundo sovavanyo, umxholo wayo oyintloko ukusasazwa kwempompo xa ukuzimisela kwentsimi eyahlukeneyo yokuhamba. ukuhamba kunye nokuchasana xa isigaba esixutywe kunye nesigaba esisodwa sokuhamba kwentsimi kwi-china slurry pump ukufana kunye nokwahlukana.
Inkqubo yovavanyo:
Ukusebenzisa ubuninzi kunye ne-viscosity ye-oyile ekrwada efana ne-oyile emhlophe yoshishino njengendlela yokuvavanya , kunye neoli emhlophe enoxinano olusondeleyo kwi-GDX501 ye-polystyrene amaso njengamasuntswana okulandelela .Iphepha lokukhanya elinamandla usebenzisa i-10W i-neon laser generator kunye nenkqubo ye-optical ehambelanayo ngenxa yokukhanya kwekhamera ye-PIV, kunye nokusetyenziswa kwevidiyo okanye iindlela zokufota ukufota imifanekiso ye-PIV.Kwiimeko ezahlukeneyo, ngokulandelanayo, phantsi kweemeko zesigaba esisodwa kunye nesigaba sesibini sokuhamba kweemeko eziphakathi kwe-china slurry pump pump tube, i-valve, i-piston kunye nezinye iindawo ze-PIV zokurekhoda komfanekiso kunye nokufota, ukulungiselela ukuhlalutya okuqhubekayo kunye nokusebenza.
Iziphumo zovavanyo kunye nohlalutyo:
Njengoko uphononongo lwempompo enzulu egxininise icandelo lokuhamba kwevalvu ineziphumo zophando ezihambelanayo, kunye nenkqubo yokwenziwa kwemifanekiso ye-gas-liquid yesigaba sesibini se-PIV ayigqibelelanga, ke apha kugxininiswe kuhlalutyo lwempompo ephakathi kwe-china slurry xa uhamba. ivalve kunye nesigaba esisodwa solwelo ikholamu iindawo zaseCypriot zebala lokuhamba.
Ukushukuma kwempompo yodaka lwaseTshayina
Kwiimvavanyo, ukuhamba kwevalve kunye nokuhlala kwimpompo ye-china ye-slurry abantu bayazi ukuba ayifani ncam, ukongeza kwimidlalo yayo ethe nkqo ye-linear motion, ehamba kunye neentshukumo ezimbini ezijikelezayo.Xa isantya sepiston esincinci, ibhola ejikeleze i-axis ethe tye yokujikeleza phantsi;Xa isantya sepiston sisikhulu, ukujikelezwa kwebhola kwi-axis ethe nkqo kunye nemingxuma ethe tye kwiikona zangaphakathi zesihlalo somngxuma wevalve embindini we-axis ye revolution.Isantya se-angular yesantya sokujikeleza sentshukumo yeplunger , isantya esikhulu sokuhamba kweplunger , ngakumbi isantya esijikelezayo se-angular yebhola.Uhlobo olukhethekileyo lokuzilolonga lunxulunyaniswa ikakhulu nefuthe lebhola kunye nebhola yevalve ewulwelo, isitulo sesitulo esinxulumeneyo.i-china slurry pump valve valve yivalve yebhola , xa ulwelo luhamba lujikeleze kwindawo yangasemva yesenzeko kuya kwenzeka ukusuka kumda womda , ngelixa uvelisa uvuyo lwamandla osecaleni .Ngenxa ye-symmetry yebhola, lomjikelo wamandla osecaleni ojikeleze ibhola ecaleni komjikelo we "ikhweyitha" ukuhambisa ibhola yevalvu ayisoloko ikumgca we-asi emgxunyeni wesihlalo, kodwa iyatenxa kumgama kwaye isondele kwisihlalo esikwikona ye-axis. ujikelezo, nto leyo ” revolution ” phenomenon.
Ukongeza, ngenxa yokungazinzi kokuhamba kolwelo kunye nokuphambuka kwebhola ye-fluid okubangelwa yintshukumo ehambelanayo yevalve yebhola i-asymmetry yebhola iya kuba nentshukumo yokukrwempa, ngoko ke ayingomandla asecaleni asebenza kumbindi wengqukuva, kodwa kumbindi webhola. Inqwelomoya ethe tyaba kunye ne-eccentricity ethile , kukho ivalve yebhola ejikelezayo kwinqwelo-moya ethe tye , okt, ” ukujikeleza ” isenzeko.Ezi zigqibo zifumaneka kwimeko yolwelo olusulungekileyo .Xa i-gas-liquid i-mixed phase flow flow , ngenxa yobukho bamaqamza , ibala lokuhamba liphazamisa kakhulu, kwaye i-bubble yebhola ineempembelelo ezithile, ngeli xesha intshukumo yebhola inzima ngakumbi, ngaphezu kokunyakaza okujikelezayo , kunye nokunyuka nokuhla kokubethwa ngobundlobongela.
Kuqukunjelwe ukuba impompo eludaka yaseChina yenziwe ukujongana nezi phuculo zilandelayo:
( 1 ) ibhola yenye yezinto eziphambili zempompo yempompo ye-slurry, nayo inxibe iinxalenye, ezimisela ukusebenza kakuhle kwempompo kunye nomjikelo wokuhlola impompo.Izindululo zempompo yenqanaba elixubeneyo lokupompoza impompo yempompo eccentric ibhola yevalufa espherical , imbaleki imxinwa yimpompo yasechina eludaka esebenzisa ibhola yentlabathi empompayo enethontsi efakwe ngempompo yasechina eludaka ivalwa kusetyenziswa ibhola yerabha ecikiziweyo.
( 2 ) kwindawo yokuqinisekisa iimeko ezingaphezulu kwe-overcurrent, i-flow cross-section shape ye-valve dome kufuneka ihlaziywe ngokusemandleni ukunciphisa ukunyanzeliswa kokuhamba.
( 3 ) ubume boyilo lweplunger , uyilo olulungelelanisiweyo kufuneka luqwalaselwe okanye isiphelo esisezantsi somlomo wentsimbi yokufunxa iplunger ukunciphisa ukuxhathisa ukufunxa.Ukuphuma kwe-Plunger kuqinisekisa ukuhamba okuphezulu kwe-cross-section, ngelixa i-outlet flow path ye-plunger yenzelwe ukulungelelaniswa ukunciphisa ukuchasana kokuhamba kwe-plunger phezu kwendawo yokuphuma.
