I-1.Ukutshintsha kwiiparamitha ze-hydraulic: ukunyuka kwengcinezelo, ukunciphisa ukuhamba, kunye nomngcipheko wokungcangcazela
Isiphumo sokuphola:Ukunciphisa ukuphuma kwamanzi kwimpompo ngokwenene kulingana nokuvala ivalve yokuphuma yempompo. Ukunciphisa i-diameter yokuphuma ilingana nokunyusa i-coefficient yokumelana nendawo. Ukulandela i-formula ye-Darcy-Weisbach, uxinzelelo lwenkqubo luya kuxhuma ngokungaqhelekanga (idatha yovavanyo ibonisa ukuba ukunciphisa i-10% yokunciphisa ububanzi kunokukhokelela ekunyukeni kwe-15-20% yoxinzelelo), ngelixa izinga lokuhamba libonisa umthetho we-Q∝A·v wokuthotywa.
Nangona amandla e-shaft ehla malunga ne-8-12% kunye nokuncipha kokuhamba, ukunyanzeliswa kwe-vibration okubangelwa i-pulsation yoxinzelelo kunokunyuka ngama-20-30%, ngokukodwa kufuphi nesantya esibalulekileyo, ekulula ukubangela i-resonance yesakhiwo.

2. Ubudlelwane phakathi kwentloko kunye noxinzelelo: Intloko yethiyori ihlala ingatshintshi, uxinzelelo lwangempela lutshintsha ngamandla
Intloko ye-oretical ihlala ingatshintshi:Intloko yethiyori ye-impeller inqunywe ngeeparamitha zejometri kwaye ayinakho ulungelelwaniso oluthe ngqo kunye nobubanzi bokuphuma kwamanzi.
Umphumo we-throttling uya kwandisa i-outlet yoxinzelelo lwempompo: Xa indawo yokusebenza yenkqubo ihamba kunye ne-HQ curve kunye nokutshintsha kwendawo yangaphandle (njengokuguquguquka kokuxhatshazwa kwenethiwekhi yombhobho), i-amplitude ye-fluctuation ye-pressure inyuka nge-30-50%, kwaye ukubikezelwa okuguquguqukayo kuyadingeka nge-curve-flow character character.
