Uma indawo yokuphuma kwephampu ishintshwa kusuka ku-6" kuya ku-4" yijoyinti, ingabe lokhu kuzoba nomthelela ephampini? Emaphrojekthini angempela, sivame ukuzwa izicelo ezifanayo. Ukunciphisa indawo yokuphuma kwamanzi ephampu kungakhuphula kancane ingcindezi yamanzi, kodwa ngenxa yokwanda kwesilinganiso sokugeleza kwephampu, kuzokhulisa ukulahleka kwamanzi.
Ake sixoxe ngomthelela wokunciphisa ipayipi lokukhipha amanzi ephampini.
Umthelela wokunciphisa i-outlet yephampu
1. Izinguquko kumapharamitha e-hydraulic: ingcindezi ekhuphukile, ukugeleza okunciphile, kanye nengozi yokudlidliza
Umphumela wokugoqa:Ukunciphisa indawo yokuphuma kwamanzi epompo empeleni kufana nokuvala ivalvu yokuphuma yepompo. Ukunciphisa ububanzi bendawo yokuphuma kufana nokwandisa i-coefficient yokumelana yendawo. Ukulandela ifomula ye-Darcy-Weisbach, ingcindezi yesistimu izogxuma ngokungaqondile (idatha yokuhlola ikhombisa ukuthi ukwehla okungu-10% ububanzi kungaholela ekukhuphukeni kwengcindezi okungu-15-20%), kuyilapho izinga lokugeleza libonisa umthetho wokunciphisa i-Q∝A·v.
Nakuba amandla omgodi ehla cishe ngo-8-12% ngokuncipha kokugeleza, amandla okudlidliza okubangelwa ukushaya kwengcindezi anganda ngo-20-30%, ikakhulukazi eduze kwesivinini esibucayi, okulula ukuvusa umsindo wesakhiwo.
2. Ubudlelwano phakathi kwekhanda nokucindezela: Ikhanda elisekelwe emcabangweni alishintshi, ukucindezela kwangempela kuyashintsha ngokuguquguqukayo
Ikhanda le-oretical alishintshi:Ikhanda eliyingqikithi le-impeller linqunywa yimingcele yejometri futhi alinawo ubudlelwano obuqondile nobubanzi bokuphuma kwamanzi.
Umphumela wokugoqa uzokwandisa ingcindezi yokukhipha yepompo: Lapho indawo yokusebenza yesistimu ihamba eceleni kwejika le-HQ kanye nendawo yangaphandle ishintsha (njengokushintshashintsha kokumelana nenethiwekhi yamapayipi), i-amplitude yokuguquguquka kwengcindezi iyanda ngo-30-50%, futhi kudingeka ukubikezela okuguquguqukayo ngejika eliyisici sokugeleza kwengcindezi.
3. Ukuthembeka kwemishini:iziphakamiso zomthelela empilweni kanye nokuqapha
Uma izimo zokusebenza zingezinhle kakhulu, kuzoba nomthelela othile empilweni yesevisi yephampu. Ukuqapha ukudlidliza kungenziwa, futhi ukuhlaziywa kwe-modal kungenziwa uma kudingeka.
4. Umkhawulo wokuphepha:imininingwane yokuguqulwa kanye nomthwalo wemoto
Imininingwane yokuvuselela:Ububanzi bokuphuma kwamanzi akufanele bube ngaphansi kuka-75% wenani lomklamo wokuqala. Ukugoba ngokweqile kuzokwenza ukuthi i-motor service factor (SF) idlule umkhawulo wokuphepha.
Uma umkhawulo wokuphepha weqiwe, ukugeleza kwamanzi okungekuhle kuzoletha ingcindezi empompini yamanzi, kwandise umthwalo wemoto, futhi imoto izogcwala ngokweqile. Uma kudingeka, amandla e-vortex kufanele abikezelwe ngokusebenzisa i-CFD simulation, futhi i-flow coefficient kufanele ilinganiswe nge-ultrasonic flowmeter ukuqinisekisa ukuthi izinga lomthwalo wemoto lilawulwa ngaphansi kuka-85% wenani elilinganisiwe.
5. Ukulawulwa kokugeleza:ubudlelwano obuqondile phakathi kobubanzi nokugeleza
Kuthinta ngqo ukugeleza kwephampu yamanzi, okungukuthi, lapho indawo yokuphuma kwamanzi yephampu yamanzi inkulu, kulapho ukugeleza kwephampu yamanzi kuba kukhulu, futhi okuphambene nalokho. (Izinga lokugeleza lihlobene kahle nendawo enqamula indawo yokuphuma kwamanzi. Ukuhlolwa kubonisa ukuthi ukwehliswa okungu-10% ububanzi kuhambisana nokwehliswa kokugeleza okungu-17-19%).
