(Incazelo efingqiwe)Umgomo wokusebenza wephampu ye-multi-stage centrifugal uyafana naleyo yephampu ye-centrifugal yaphansi.
Umgomo wokusebenza wephampu ye-multi-stage centrifugal uyafana naleyo yephampu ye-centrifugal yaphansi. Lapho i-motor ishayela i-impeller ku-shaft ukuze ijikeleze ngesivinini esikhulu, uketshezi olugcwaliswe ku-impeller luzophonswa kusukela phakathi nendawo ye-impeller endleleni yokugeleza phakathi kwama-blades kuya ku-periphery ye-impeller ngaphansi kwesenzo samandla we-centrifugal. Ngenxa yesenzo sezindwani, uketshezi lwandisa ingcindezi nesivinini ngesikhathi esifanayo, futhi luqondiswa kwesilandelayo-i-impeller yesiteji ngephaseji lokugeleza kwegobolondo lomhlahlandlela. Ngale ndlela, igeleza kuwo wonke ama-impellers kanye negobolondo lomhlahlandlela ngamunye ngamunye, ngokuqhubekayo ukwandisa amandla okucindezela okwanda kwe-liquid. Ngemva kokupakisha i-impeller ngayinye isinyathelo ngesinyathelo, kutholakala ikhanda elithile futhi uketshezi lwe-downhole luphakanyiswe phansi. Lona umgomo wokusebenza we-stainless steel multi-stage pump.
Izici eziyinhloko ze-multistage centrifugal pump:
1. Isakhiwo esiqondile, i-inlet ne-outlet flanges kumugqa ofanayo ophakathi, isakhiwo sihlangene, indawo incane, futhi ukufakwa kulula.
2. Iphampu yesakhiwo esime mpo yamukela uphawu lwemishini yesakhiwo sesitsha, okwenza umsebenzi wokufaka nowokulungisa uphephe futhi ube lula, futhi iqinisekisa ukwethembeka kophawu.
3. I-motor shaft yepompo ye-multi-stage centrifugal ixhunywe ngokuqondile ne-pump shaft ngokusebenzisa i-coupling.
4. Ipompo enezingqimba ifakwe injini ye-shaft enwetshiwe, enesakhiwo esilula futhi kulula ukuyifaka nokuyigcina.
5. Izingxenye zokugeleza zonke zenziwe ngensimbi engagqwali, engangcolisi i-medium futhi iqinisekisa impilo ende yesevisi nokubukeka okuhle.
6. Umsindo ophansi nokudlidliza okuncane. Ngomklamo osezingeni, unokuguquguquka okuhle.
Yiziphi izindlela zokulungisa amaphampu e-centrifugal amaningi? Izindlela ezimbili ezisetshenziswa kakhulu ziyenziwa:
1. I-valve throttling
Indlela elula yokushintsha izinga lokugeleza kwephampu ye-centrifugal ukuguqula ukuvulwa kwe-valve ye-pump autlet, kuyilapho ijubane lephampu ye-multi - Isigaba sephampu esigabeni sihlala singashintshiwe (ngokuvamile ijubane elikalwe). Umnyombo ukushintsha isikhundla sejika lesici sepayipi ukuze ushintshe indawo yokusebenza yempompo. Ukuhlangana kwe-Pump Acdication Curve Q - H kanye ne-Pipeline Curve Q - ΣH Iphuzu elisebenzayo elisebenzayo lepompo lapho i-valve ivulwa ngokuphelele. Lapho i-valve ivaliwe, ukumelana kwendawo kwepayipi kuyanda, iphuzu lokusebenza lempompo liya ngakwesobunxele, futhi ukuhamba okuhambisanayo kuyancipha. Lapho i-valve ivaliwe ngokuphelele, ilingana nokumelana okungenamkhawulo kanye nokugeleza kwe-zero. Ngalesi sikhathi, ijika lemifanekiso yepayipi lihlangana ngokudidiyela. Kungabonakala ukuthi lapho i-valve ivaliwe ukulawula ukugeleza, umthamo wokuhlinzeka ngamanzi we-Multi - Isigaba sePuprifugal Iphampu uqobo ihlala ingashintshiwe, izici zepayipi zihlala zingashintshiwe, futhi izici zepayipi zihlala zingaguquki, futhi izici zepayipi zihlala zingaguquki, futhi izici zokuphikiswa kwamapayipi zizoshintsha ngoshintsho lokuvulwa kwe-valve. Le ndlela kulula ukuyisebenzisa, iqhubeka nokugeleza, futhi ingashintshwa ngentando phakathi kokugeleza okuthile okukhulu kanye ne-zero, ngaphandle kokutshala imali eyengeziwe, futhi inezinhlobonhlobo zezicelo. Kodwa-ke, ukulungiswa okuphoqayo ukuqeda amandla ngokweqile kwepompo ye-centrifugal ukuze ulondoloze ukuhlinzekwa okuthile, futhi ukusebenza kahle kwephampu ye-centrifugal nakho kuzokwehla ngokufanele, okungafanele ngokomnotho.
2. Ukulawulwa kwesivinini sokuguqulwa kwemvamisa
Ukuchezuka kwendawo yokusebenza ukusuka endaweni-esebenza kahle kakhulu kuyisimo esiyisisekelo sejubane lephampu. Lapho isivinini sepompo ye-centrifugal ye-multistage sishintsha, ukuvulwa kwe-valve kuhlala kungashintshiwe (ngokuvamile ukuvuleka okukhulu), izici zesistimu yamapayipi zihlala zingashintshiwe, futhi umthamo wokuphakelwa kwamanzi kanye nezici zekhanda zishintsha ngokufanele. Uma ukugeleza okudingekayo kungaphansi kokugeleza okulinganiselwe, inhloko yokulawulwa kwesivinini sokuguqulwa kwemvamisa incane kune-valve throttling, ngakho-ke amandla okunikezwa kwamanzi adingekayo kumthethonqubo wesivinini sokuguqulwa kwemvamisa nawo mancane kune-valve throttling. Ngokusobala, uma kuqhathaniswa ne-valve throttling, umthelela-wonga amandla wokulawula isivinini sokuguqulwa kwemvamisa ugqame kakhulu, futhi ukusebenza kahle kwamaphampu amaphakathi amaningi - esiteji avundlile kuphezulu. Ukwengeza, ukusetshenziswa kokulawulwa kwesivinini sokuguqulwa kwemvamisa akusizi nje kuphela ukunciphisa amathuba okuba ne-cavitation kupompo ye-centrifugal, kodwa futhi kwandisa inqubo yokuqala / yokumisa ngokumisa kusengaphambili isikhathi sokukhuphuka / phansi, ukuze i-torque eguquguqukayo iyancipha kakhulu. , Ngaleyo ndlela iqeda umphumela wesando samanzi esibhubhisayo ngezinga elikhulu, ukwandisa kakhulu impilo yephampu kanye nesistimu yamapayipi.
Iphampu ephakathi kwesiteji - Inezinzuzo zokusebenza kahle kakhulu nokonga amandla, ububanzi bokusebenza okubanzi, ukusebenza okuphephile nokuzinzile, umsindo ophansi, impilo ende, ukufakwa nokugcinwa okulula, njll.; ngokushintsha impahla yepompo, ukuvala ifomu nokwandisa ukupholisa Uhlelo lungakwazi ukuthutha amanzi ashisayo, uwoyela, imidiya egqwalayo kanye ne-abrasive, njll. Abakhiqizi bephampu yezigaba eziningi abahlukene bakhiqiza amamodeli ahlukene amaphampu aphakathi kwezigaba eziningi. Amaphampu e-Multi-stage centrifugal ahlanganisa amaphampu amabili noma ngaphezulu anomsebenzi ofanayo ndawonye. Isakhiwo somzila owuketshezi sibonakala embobeni yokusiza ingcindezi yabezindaba kanye nesigaba sokuqala. I-inlet yesigaba sesibili ixhunyiwe, futhi imbobo yokusiza ingcindezi ephakathi yesigaba sesibili ixhunywe ekungeneni kwesigaba sesithathu. Uchungechunge olunjalo-umshini oxhumene wakha iphampu ye-multi-stage centrifugal. Ukubaluleka kwephampu ye-multistage centrifugal ukukhulisa ingcindezi ebekiwe.
