Ukuba indawo yokuphuma kwepompo itshintshwa ukusuka kwi-6" ukuya kwi-4" yijoyinti, ngaba oku kuya kuba nefuthe kwipompo? Kwiiprojekthi zokwenyani, sihlala siva izicelo ezifanayo. Ukunciphisa indawo yokuphuma kwamanzi kwipompo kunokunyusa uxinzelelo lwamanzi kancinci, kodwa ngenxa yokwanda kwesantya sokuhamba kwepompo, kuya kunyusa ilahleko ye-hydraulic.
Masithethe ngempembelelo yokunciphisa iplagi yepompo kwipompo.
Impembelelo yokunciphisa i-outlet yepompo
1. Utshintsho kwiiparameter ze-hydraulic: uxinzelelo olunyukileyo, ukuncipha kokuhamba kwamanzi, kunye nomngcipheko wokungcangcazela
Isiphumo sokuqhobosha:Ukunciphisa indlela yokuphuma kwamanzi kwimpompo kuyafana nokuvala ivalvu yokuphuma kwimpompo. Ukunciphisa ububanzi bendlela yokuphuma kuyafana nokwandisa i-coefficient yokumelana yendawo. Ukulandela ifomula yeDarcy-Weisbach, uxinzelelo lwenkqubo luya kutsiba ngokungangqalanga (idatha yovavanyo ibonisa ukuba ukunciphisa i-10% kwi-dayamitha kunokukhokelela ekonyukeni kwe-15-20% kuxinzelelo), ngelixa izinga lokuhamba kwamanzi libonisa umthetho wokunciphisa i-Q∝A·v.
Nangona amandla eshaft ehla malunga ne-8-12% xa kuncipha ukuhamba, amandla okungcangcazela okubangelwa kukubetha koxinzelelo anokunyuka ngama-20-30%, ingakumbi kufutshane nesantya esibalulekileyo, okulula ukubangela ukurhawuzelelwa kwesakhiwo.
2. Ubudlelwane phakathi kwentloko noxinzelelo: Intloko yethiyori ayitshintshi, uxinzelelo lokwenyani luyatshintsha ngokuguquguqukayo
Intloko ye-ortical ayitshintshanga:Intloko yethiyori ye-impeller imiselwa ziiparameter zejometri kwaye ayinalo ulwalamano oluthe ngqo nobubanzi bokuphuma kwamanzi.
Isiphumo sokubhoboza siya kwandisa uxinzelelo lokukhupha lwepompo: Xa indawo yokusebenza kwenkqubo ihamba ecaleni kwegophe le-HQ kwaye imeko-bume yangaphandle itshintsha (njengokuguquguquka kokumelana nenethiwekhi yepayipi), i-amplitude yokuguquguquka koxinzelelo iyanda nge-30-50%, kwaye kufuneka uqikelelo oluguquguqukayo ngokusebenzisa igophe elibonisa ukuhamba koxinzelelo.
3. Ukuthembeka kwezixhobo:impembelelo ebomini kunye neengcebiso zokubeka esweni
Ukuba iimeko zokusebenza azilunganga kangako, kuya kuba nefuthe elithile kubomi benkonzo yepompo. Ukubeka iliso ekungcangcazeleni kungenziwa, kwaye ukwenziwa ngcono kohlalutyo lwemodyuli kungenziwa ukuba kuyimfuneko.
4. Umda wokhuseleko:iinkcukacha zokuguqulwa kunye nomthwalo wemoto
Iinkcukacha zohlaziyo:Ububanzi bokuphuma kwamanzi akufuneki bube ngaphantsi kwe-75% yexabiso loyilo lokuqala. Ukugoba kakhulu kuya kubangela ukuba i-motor service factor (SF) idlule umda wokhuseleko.
Ukuba umda wokhuseleko udluliwe, ukuhamba kwamanzi okubi kuya kuzisa uxinzelelo kwimpompo yamanzi, kwandise umthwalo wemoto, kwaye imoto iya kugcwala kakhulu. Ukuba kuyimfuneko, amandla evortex kufuneka aqikelelwe ngokusebenzisa i-CFD simulation, kwaye i-flow coefficient kufuneka ilinganiswe nge-ultrasonic flowmeter ukuqinisekisa ukuba izinga lomthwalo wemoto lilawulwa ngaphantsi kwe-85% yexabiso elilinganisiweyo.
5. Ulawulo lokuhamba kwamanzi:ulwalamano oluthe ngqo phakathi kobubanzi kunye nokuhamba kwamanzi
Ichaphazela ngokuthe ngqo ukuhamba kwepompo yamanzi, oko kukuthi, xa ipompo yamanzi inkulu, kokukhona ipompo yamanzi ikhula kakhulu, kwaye ngokuchaseneyo. (Isantya sokuhamba kwamanzi sihambelana kakuhle nendawo enqamlezileyo yepompo yamanzi. Uvavanyo lubonisa ukuba ukunciphisa kwe-10% ububanzi kuhambelana nokunciphisa kwe-17-19% yokuhamba kwamanzi)
