Iphampu ye-Centrifugal isetshenziswa kakhulu ekongiweni kwamanzi, embonini yamakhemikhali nakwezinye izimboni, ukukhetha indawo yayo yokusebenza kanye nokuhlaziywa kokusetshenziswa kwamandla kuya ngokuya kubaluleka. Okubizwa ngokuthi iphoyinti lokusebenza, kubhekisela kudivayisi yepompo ekuphumeni kwamanzi kwangempela ngokushesha, ikhanda, amandla e-shaft, ukusebenza kahle kanye nokuphakama kwe-vacuum yokudonsa, njll., imele amandla okusebenza wepompo. Ngokuvamile, ukugeleza kwepompo ye-centrifugal, ikhanda lokucindezela kungase kungahambisani nesistimu yepayipi, noma ngenxa yomsebenzi wokukhiqiza, izidingo zenqubo ziyashintsha, isidingo sokulawula ukugeleza kwepompo, ingqikithi yalo ukushintsha indawo yokusebenza yepompo ye-centrifugal. Ngokungeziwe kusigaba sokuklama kobunjiniyela sokukhethwa kwephampu ye-centrifugal kulungile, ukusetshenziswa kwangempela kwephuzu lokusebenzisa iphampu elimaphakathi nakho kuzothinta ngokuqondile ukusetshenziswa kwamandla omsebenzisi kanye nezindleko. Ngakho-ke, indlela yokushintsha ngokunengqondo indawo yokusebenza yephampu ye-centrifugal ibaluleke kakhulu. Indawo yokusebenza yephampu eyi-centrifugal isekelwe ebhalansi phakathi kokunikezwa kanye nesidingo samandla wepompo kanye nesistimu yamapayipi. Uma nje esinye sezimo ezimbili sishintsha, indawo yokusebenza izoshintsha. Ukushintsha kwendawo yokusebenza kubangelwa izici ezimbili: okokuqala, ukuguqulwa kwejika lesici sesistimu yamapayipi, njenge-valve throttling; Okwesibili, izici zepompo yamanzi ngokwazo ziyashintsha ijika, njengejubane lokuguqulwa kwemvamisa, i-impeller yokusika, uchungechunge lwepompo yamanzi noma ukuhambisana.

Izindlela ezilandelayo ziyahlaziywa futhi ziqhathaniswe:
Ukuvalwa kwe-valve: indlela elula yokushintsha ukugeleza kwephampu ye-centrifugal ukulungisa ukuvuleka kwe-valve yokuphuma kwepompo, futhi isivinini sepompo sihlala singashintshiwe (isivinini esilinganiselwe ngokuvamile), ingqikithi yayo ukuguqula indawo yejika lezimpawu zamapayipi ukushintsha ukusebenza kwepompo. iphuzu. Lapho i-valve ivaliwe, ukumelana kwendawo kwepayipi kwanda futhi indawo yokusebenza yepompo ihamba ngakwesobunxele, ngaleyo ndlela kunciphisa ukugeleza okuhambisanayo. Uma i-valve ivalwe ngokuphelele, ilingana nokumelana okungapheli kanye nokugeleza kwe-zero. Ngalesi sikhathi, ijika lesici sepayipi lihambisana nokuxhumanisa okuqondile. Lapho i-valve ivaliwe ukulawula ukugeleza, amandla okuhambisa amanzi epompo ngokwawo ahlala engashintshi, izici zokuphakamisa zihlala zingashintshiwe, futhi izici zokumelana nepayipi zizoshintsha ngokushintsha kokuvula i-valve. Le ndlela ilula ukuyisebenzisa, ukugeleza okuqhubekayo, kungalungiswa ngokuthanda kwakho phakathi kokugeleza okuphezulu noziro, futhi alukho utshalomali olwengeziwe, olusebenza ezikhathini eziningi. Kodwa ukulawulwa kwe-throttling kuwukusebenzisa amandla engeziwe wephampu ye-centrifugal ukuze kugcinwe inani elithile lokuhlinzeka, futhi ukusebenza kahle kwephampu ye-centrifugal nakho kuzokwehla, okungafaneleki ngokomnotho.

Ukulawulwa kwesivinini sefrikhwensi eguquguqukayo kanye nokuchezuka kwendawo yokusebenza ukusuka endaweni esebenza kahle kakhulu yizimo eziyisisekelo zokulawula isivinini sephampu. Lapho isivinini sepompo sishintsha, ukuvulwa kwe-valve kuhlala kufana (ngokuvamile ukuvulwa okuphezulu), izici zesistimu yamapayipi zihlala zifana, futhi umthamo wokuphakelwa kwamanzi kanye nezici zokuphakamisa zishintsha ngokufanele.
Endabeni yokugeleza okudingekayo okungaphansi kokugeleza okulinganiselwe, inhloko yokulawulwa kwesivinini esishintshashintshayo incane kune-valve throttling, ngakho isidingo sokulawulwa kwesivinini esishintshashintshayo samandla okunikezwa kwamanzi sincane kune-valve throttling. Ngokusobala, uma kuqhathaniswa ne-valve throttling, umphumela wokonga isivinini sokuguqulwa kwemvamisa ugqame kakhulu, ukusebenza kahle kwepompo ye-centrifugal kuphezulu. Ukwengeza, ukusebenzisa ukulawulwa kwesivinini esishintshashintshayo, akuzuzisi nje kuphela ukunciphisa ingozi yokuthuthukisa i-cavitation kupompo ye-centrifugal, futhi ingalawulwa isikhathi se-acc/dec ukuze sandise inqubo yokusetha kabusha yokuqala / yokumisa, ngaleyo ndlela inciphise kakhulu i-torque enamandla, ngaleyo ndlela iqedwe ziyahlukahluka kakhulu futhi elimazayo amanzi isando umphumela, kakhulu ukwandisa isikhathi sokuphila futha kanye amapayipi uhlelo.

Eqinisweni, ukulawulwa kwesivinini sokuguqulwa kwemvamisa nakho kunemikhawulo, ngaphezu kokutshalwa kwezimali okukhulu, izindleko zokunakekelwa okuphezulu, lapho isivinini sepompo sizoba sikhulu kakhulu sizobangela ukwehla kokusebenza kahle, ngaphezu kobubanzi bomthetho wokulinganisa wepompo, akunakwenzeka ngesivinini esingenamkhawulo.

I-impeller yokusika: lapho ijubane liqinisekile, ikhanda lokucindezela kwepompo, ukugeleza kanye nobubanzi be-impeller. Ngohlobo olufanayo lwepompo, indlela yokusika ingasetshenziswa ukushintsha izici zejika lepompo.

Umthetho wokusika usekelwe enanini elikhulu ledatha yokuhlolwa kokuqonda, ucabanga ukuthi uma inani lokusika le-impeller lilawulwa ngaphakathi komkhawulo othile (umkhawulo wokusika uhlobene nokuguqulwa okuthile kwepompo), khona-ke ukusebenza kahle okuhambisanayo iphampu ngaphambi nangemva kokusika ingathathwa njengengashintshiwe. I-Cutting impeller iyindlela elula futhi elula yokuguqula ukusebenza kwepompo yamanzi, okungukuthi, lokho okubizwa ngokuthi ukulungiswa kokunciphisa ububanzi, okuxazulula izinga elithile ukungqubuzana phakathi kohlobo olulinganiselwe kanye nokucaciswa kwepompo yamanzi kanye nokuhlukahluka kokunikezwa kwamanzi. izidingo zento, futhi andise ububanzi bokusetshenziswa kwepompo yamanzi. Yiqiniso, i-impeller yokusika iyinqubo engenakuhlehliswa; umsebenzisi kufanele abalwe ngokunembile futhi akalwe ngaphambi kokuthi kusetshenziswe ubuhlakani bomnotho.

Uchungechunge oluhambisanayo: uchungechunge lwephampu yamanzi lubhekisela ekuphumeni kwepompo ukuya endaweni yokufaka enye iphampu ukuze kudluliselwe uketshezi. Kumodeli elula kakhulu emibili efanayo nokusebenza okufanayo kochungechunge lwephampu ye-centrifugal, isibonelo: ijika lokusebenza lochungechunge lilingana nejika lepompo elilodwa lokusebenza lekhanda ngaphansi kokugeleza okuphezulu okufanayo, nokuthola uchungechunge lokugeleza nekhanda kukhulu kune-curve yokusebenza kwephampu eyodwa. Iphuzu elilodwa lokusebenza lephampu B, kodwa lishoda ngepompo eyodwa izikhathi ezi-2 kunosayizi, lokhu kungenxa yokuthi uchungechunge lwepompo ngemuva kwesinye isandla, ukwanda kokuphakanyiswa kukhulu kunokwenyuka kokumelana namapayipi, insalela yokugeleza kwamandla okuphakamisa iyanda, ukwanda kwezinga lokugeleza nokwandisa ukumelana ngakolunye uhlangothi, kuvimbela ukwanda kwekhanda eliphelele. , ukusebenza kochungechunge lwephampu yamanzi, kufanele kunake okokugcina lapho iphampu ingakwazi ukumelana nomfutho. Ngaphambi kokuqala kwe-valve yokuphuma kwepompo ngayinye kufanele ivalwe, bese ukulandelana kokuvula iphampu kanye ne-valve ukunikeza amanzi.

Iphampu lamanzi parallel lisho amaphampu amabili noma angaphezu kwamabili ephayiphini elifanayo lomfutho wokulethwa koketshezi; inhloso yawo ukukhulisa ukugeleza ekhanda elifanayo. Kusesezilula kakhulu ezinhlotsheni ezimbili ezifanayo, iphampu ye-centrifugal efanayo ngokuhambisana njengesibonelo, ukusebenza kwejika elihambisanayo lilingana nejika lepompo elilodwa lokusebenza lokugeleza ngaphansi kwesimo sekhanda lilingana ne-superposition, umthamo kanye Inhloko yendawo yokusebenza ehambisanayo A yayinkulu kunephuzu elilodwa lokusebenza lephampu B, kodwa cabangela isici sokumelana nepayipi, futhi ishoda ngephampu eyodwa izikhathi ezi-2.

Uma inhloso kuwukukhuphula izinga lokugeleza, khona-ke ukuthi ukusebenzisa i-parallel noma uchungechunge kufanele kuncike ekucaba kwejika lesici sepayipi. Uma ijika lesici sephayiphi liba isicaba, izinga lokugeleza ngemva kokufana lisondela ngokuphindwe kabili kunelokusebenza kwephampu eyodwa, ukuze izinga lokugeleza libe likhulu kunalelo ochungechungeni, oluvumela kakhulu ukusebenza.

Isiphetho: Nakuba i-valve throttling ingase ibangele ukulahlekelwa amandla kanye nokumoshakala, kuseyindlela esheshayo nelula yokulawula ukugeleza kwezinye izikhathi ezilula. Ukulawulwa kwesivinini sokuguqulwa kwemvamisa kuthandwa kakhulu ngabasebenzisi ngenxa yomphumela wawo omuhle wokonga kanye nezinga eliphezulu lokuzenzakalelayo. I-impeller yokusika ngokuvamile isetshenziselwa ukuhlanza ipompo yamanzi, ngenxa yokuguqulwa kwesakhiwo sepompo, ukujwayelekile kumpofu; Uchungechunge lwephampu nokuhambisana kulungele kuphela iphampu eyodwa ayikwazi ukuhlangabezana nomsebenzi wokudlulisa isimo, nochungechunge noma okuhambisanayo kuningi kakhulu kodwa hhayi ngokomnotho. Ekusetshenzisweni okungokoqobo, kufanele sicabangele ezicini eziningi futhi sihlanganise uhlelo olungcono kakhulu ezindleleni zokulawula ukugeleza okuhlukahlukene ukuze siqinisekise ukusebenza kahle kwephampu ye-centrifugal.
