Ipompo ye-Centrifugal isetyenziswa ngokubanzi kulondolozo lwamanzi, imboni yeekhemikhali kunye namanye amashishini, ukhetho lwendawo yokusebenza kunye nohlalutyo lokusetyenziswa kwamandla luya kuxabiswa. Into ebizwa ngokuba yindawo yokusebenza, ibhekisela kwisixhobo sempompo kwisiphumo esithile sangempela samanzi ngokukhawuleza, intloko, amandla e-shaft, ukusebenza kakuhle kunye nokuphakama kwe-vacuum yokufunxa, njl., imele amandla okusebenza kwempompo. Ngokuqhelekileyo, ukuhamba kwempompo ye-centrifugal, intloko yoxinzelelo ayinakuhambelana nenkqubo yombhobho, okanye ngenxa yomsebenzi wokuvelisa, iimfuno zenkqubo zitshintsha, imfuno yokulawula ukuhamba kwempompo, isiseko sayo kukutshintsha indawo yokusebenza yempompo ye-centrifugal. Ukongeza kwinqanaba loyilo lobunjineli bokukhethwa kwempompo ye-centrifugal ichanekile, ukusetyenziswa kwangempela kwendawo yokusebenza yempompo ye-centrifugal kuya kuchaphazela ngokuthe ngqo ukusetyenziswa kwamandla kunye neendleko zomsebenzisi. Ngoko ke, indlela yokutshintsha ngokufanelekileyo indawo yokusebenza yempompo ye-centrifugal ibaluleke kakhulu. Indawo yokusebenza yempompo ye-centrifugal isekelwe kwibhalansi phakathi kokunikezelwa kunye nemfuno yamandla epompo kunye nenkqubo yombhobho. Ngethuba nje enye yeemeko ezimbini zitshintsha, indawo yokusebenza iya kutshintsha. Ukutshintsha kwendawo yokusebenza kubangelwa yimiba emibini: okokuqala, ukuguqulwa kwegophe leempawu zenkqubo yombhobho, njenge-valve throttling; Okwesibini, iimpawu zempompo zamanzi ngokwazo zitshintsha ijika, njengesantya sokuguqula isantya, i-impeller yokusika, uchungechunge lwempompo yamanzi okanye ukuhambelana.

Ezi ndlela zilandelayo ziyahlalutywa kwaye zithelekiswe:
Ukuvalwa kweValve: eyona ndlela ilula yokutshintsha ukuhamba kwempompo ye-centrifugal kukulungelelanisa ukuvulwa kwevalve yempompo, kwaye isantya sempompo sihlala singatshintshi (isantya esilinganiselwe ngokubanzi), undoqo wayo kukutshintsha indawo yegophe leempawu zemibhobho ukuguqula ukusebenza kwempompo. inqaku. Xa i-valve ivaliwe, ukuchasana kwendawo yombhobho kwanda kwaye indawo yokusebenza yempompo ihamba ngakwesobunxele, ngaloo ndlela inciphisa ukuhamba okuhambelanayo. Xa i-valve ivaliwe ngokupheleleyo, ilingana nokuchasana okungapheliyo kunye nokuhamba kwe-zero. Ngeli xesha, ijika leempawu zombhobho lihambelana nolungelelwaniso oluthe nkqo. Xa i-valve ivaliwe ukulawula ukuhamba, umthamo wokunikezelwa kwamanzi wempompo ngokwawo uhlala ungatshintshi, iimpawu zokuphakamisa zihlala zingatshintshi, kwaye iimpawu zokumelana nombhobho ziya kutshintsha ngokutshintsha kokuvulwa kwevalve. Le ndlela ilula ukusebenza, ukuhamba okuqhubekayo, kunokulungelelaniswa ngokuthanda phakathi kokuhamba okuphezulu kunye ne-zero, kwaye akukho tyalo-mali olongezelelweyo, olusebenzayo kuluhlu olubanzi lwezihlandlo. Kodwa ukulawulwa kwe-throttling kukusebenzisa amandla angaphezulu kwempompo ye-centrifugal ukugcina inani elithile lokubonelela, kunye nokusebenza kakuhle kwempompo ye-centrifugal kuya kuncipha, okungekho ngqiqweni kwezoqoqosho.

Ukulawulwa kwesantya sokuhamba kwamaza okuguquguqukayo kunye nokutenxa kwindawo yokusebenza ukusuka kwindawo yobuchule obuphezulu ziimeko ezisisiseko zolawulo lwesantya sempompo. Xa isantya sempompo sitshintsha, ukuvulwa kwevalve kuhlala kufana (ngokuqhelekileyo ukuvulwa okukhulu), iimpawu zenkqubo yokubhobhoza zihlala zifana, kunye nomthamo wokunikezelwa kwamanzi kunye neempawu zokuphakamisa zitshintsha ngokufanelekileyo.
Kwimeko yokuqukuqela okufunekayo okungaphantsi komlinganiselo wokuqukuqela, intloko yolawulo lwesantya esitshintshayo incinci kunevalve throttling, ngoko ke imfuno yolawulo lwesantya esiguquguqukayo samandla onikezelo lwamanzi incinci kunevalve throttling. Ngokucacileyo, xa kuthelekiswa ne-valve throttling, isantya sokuguqulwa kwesantya sokuguqulwa kwesantya siphawuleka kakhulu, ukusebenza kwempompo ye-centrifugal kuphezulu. Ukongeza, ukusebenzisa ukulawulwa kwesantya sokujikeleza okuguquguqukayo, akuncedi kuphela ukunciphisa umngcipheko wokuphuhlisa i-cavitation kwipompo ye-centrifugal, kwaye inokulawulwa yi-acc / dec ixesha lokwandisa inkqubo yokusetha kwangaphambili / yokumisa, ngaloo ndlela inciphisa kakhulu i-torque enamandla, ngaloo ndlela isuswe ziyahluka kakhulu kwaye ezonakalisayo isiphumo sehamile yamanzi, yandisa kakhulu ubude bobomi bempompo kunye nenkqubo yemibhobho.

Enyanisweni, ukulawulwa kwesantya sokuguqulwa kwamaxesha amaninzi nako kunemida, ngaphezu kotyalo-mali olukhulu, iindleko eziphezulu zokugcina, xa isantya sempompo siya kuba sikhulu kakhulu siya kubangela ukwehla kokusebenza kakuhle, ngaphaya kwendawo yomthetho wokulinganisa wempompo, akunakwenzeka ukukhawuleza okungenamkhawulo.

I-impeller yokusika: xa isantya siqinisekile, intloko yoxinzelelo lwempompo, ukuhamba kunye nobubanzi be-impeller. Kuhlobo olufanayo lwempompo, indlela yokusika ingasetyenziselwa ukutshintsha iimpawu ze-curve yepompo.

Umthetho wokusika usekelwe kwinani elikhulu ledatha yovavanyo lokuqonda, ucinga ukuba ukuba umlinganiselo wokusika we-impeller ulawulwa ngaphakathi komda othile (umda wokusika uhambelana ne-revolution ethile yempompo), ngoko ukusebenza okuhambelanayo umpompo ngaphambi nangemva kokusikwa kunokubonwa njengento engatshintshiyo. Ukusika i-impeller yindlela elula kwaye elula yokutshintsha ukusebenza kwempompo yamanzi, oko kukuthi, into ebizwa ngokuba yi-diameter yokunciphisa uhlengahlengiso, okuya kuthi kwinqanaba elithile isombulule ukuchasana phakathi kohlobo oluqingqiweyo kunye nokucaciswa kwempompo yamanzi kunye nokuhlukahluka kokunikezelwa kwamanzi. iimfuno zezinto, kunye nokwandisa umda wokusetyenziswa kwempompo yamanzi. Kakade ke, i-impeller yokusika yinkqubo engenakuguqulwa; umsebenzisi kufuneka abalwe ngokuchanekileyo kwaye alinganiswe phambi kokuba uqikelelo lwezoqoqosho luphunyezwe.

Uchungechunge oluhambelanayo: uchungechunge lwempompo yamanzi lubhekiselele ekuphumeni kwempompo ukuya kwindawo yokungena yenye impompo yokudlulisa ulwelo. Kweyona modeli ilula ezimbini ezifanayo kunye nokusebenza okufanayo kothotho lwempompo ye-centrifugal, umzekelo: igophe yokusebenza kwempompo ilingana nomjikelo wokusebenza wempompo omnye wentloko phantsi komgangatho ofanayo wokuqukuqela, kwaye ufumane uthotho lokuhamba kunye nentloko zikhulu kunoko. Ipompa enye indawo yokusebenza yempompo B, kodwa imfutshane kwimpompo enye ngokuphindwe kabini ubukhulu, oku kungenxa yokuba uthotho lwempompo emva kwelinye icala, ukonyuka konyuso kukhulu kunokonyuka koxhathiso lwemibhobho, intsalela yokunyuka kwamandla okunyusa kuyenyuka, ukunyuka kwezinga lokuhamba kunye nokwandisa ukuchasana kwelinye icala, ukuvimbela ukwanda kwentloko epheleleyo. , ukusebenza uthotho impompo yamanzi, kufuneka sinikele ingqalelo yokugqibela impompo inokumelana ukunyusa. Ngaphambi kokuqala kwevalve yokukhupha impompo nganye kufuneka ivalwe, kwaye emva koko ulandelelwano lokuvula impompo kunye nevalve ukunika amanzi.

Impompo yamanzi ngokunxuseneyo ibhekiselele kwiimpompo ezimbini okanye ngaphezulu kwesibini kumbhobho woxinzelelo ofanayo wokuhanjiswa kolwelo; injongo yalo kukwandisa ukuhamba kwentloko enye. Kusekweyona nto ilula kakhulu yohlobo olufanayo, impompo ye-centrifugal efanayo ngokuhambelana njengomzekelo, ukusebenza kwegophe elihambelanayo lilingana nomjikelo wokusebenza wempompo omnye wokuhamba phantsi kwemeko yentloko ilingana ne-superposition, umthamo kunye intloko yendawo yokusebenza ehambelanayo A ibinkulu kunempompo enye yokusebenza kwindawo B, kodwa qwalasela into yokumelana nombhobho, nayo imfutshane kumpompo enye amaxesha ama-2.

Ukuba injongo kukunyusa izinga lokuhamba, ngoko ke ukuba kusetyenziswe i-parallel okanye uchungechunge kufuneka kuxhomekeke ekuphakameni kwegophe lophawu lombhobho. Igophe lephawu lombhobho lithe kratya, kokukhona izinga lokuqukuqela emva kokunxulunyaniswa lisondele kabini kunelo lokusebenza lwempompo enye, ukuze izinga lokuhamba libe likhulu kunolo kuthotho, olulungele ukusebenza.

Ukuqukumbela: Nangona ukubetheka kwevalve kunokubangela ukulahleka kwamandla kunye nenkcitho, kuseyindlela ekhawulezayo nelula yokulawula ukuhamba kwezinye iimeko ezilula. Ulawulo lwesantya soguqulo lwesantya luthandeka ngakumbi nangakumbi ngabasebenzisi ngenxa yesiphumo esihle sokonga amandla kunye nenqanaba eliphezulu lokuzenzela. I-impeller yokusika ngokuqhelekileyo isetyenziselwa ukucoca impompo yamanzi, ngenxa yokutshintsha kwesakhiwo sempompo, isiqhelo sihlupheka; Uchungechunge lwepompo kunye ne-parallel ifanelekile kuphela kwipompo enye ayikwazi ukuhlangabezana nomsebenzi wokuhambisa imeko, kunye nochungechunge okanye ukuhambelana kakhulu kodwa kungekhona uqoqosho. Kwisicelo esisebenzayo, kufuneka siqwalasele kwiinkalo ezininzi kwaye sidibanise iskimu esihle kwiindlela ezahlukeneyo zokulawula ukuhamba ukuze kuqinisekiswe ukusebenza kakuhle kwempompo ye-centrifugal.
