Izinto ze-1: izinto eziphathekayo ze-slurry pump impeller kunye ne-volute, njengezinto ezi-elastic ezifana ne-rubber, i-neoprene, i-polyurethane resin, esetyenziswa ngokuqhelekileyo kwimeko ye-impeller ye-outlet velocity iphantsi kwe-23 m / s, enokuphucula ipompo ye-NPSH ngokufanelekileyo.
Amasuntswana ama-2 aqinileyo kwimpembelelo yempompo ye-centrifugal, ukuhamba kwempompo eludaka - ijika lokuphakamisa lithe tyaba, kwaye ilahleko yokumelana nokuhamba kombhobho iya kwanda ngokunyuka kwetrafikhi kunye nokucotha, ijika leempawu zemibhobho kunye ne-Angle yokusebenza incinci, i intloko yotshintsho oluncinci lunokubangela utshintsho olukhulu.
3 uyilo lomatshini, i-shaft, ukuthwala, itywina, umzimba wempompo, njl.njl.) : shaft kunye nokuthwala kufuneka zibe namandla aphezulu kunye nokuqina kunye nokuthembeka. I-trapezoidal screw connection impeller ngokubanzi inokumelana nomthwalo onzima, phantsi kwemeko yomthwalo onzima usebenzisa i-sliding thrust bearing kunye nebhola yebhola isetyenziswa ngokuqhelekileyo kwiimeko zomthwalo okhanyayo.
Ukunxitywa kwe-4 kunye nokusebenza kwe-hydraulic yengxaki: ukuze kuncitshiswe ukuguga kunye nokukrazula, kufuneka kugcinwe amacandelo ajikelezayo kunye nesantya solwelo sisezantsi ngokwaneleyo, ukupompa umzimba oqinileyo we-alloy lining okanye i-elastic lubrication lubrication material cross section ubukhulu kufuneka bonyuswe, ukuze kuhlangatyezwane neemfuno. yokusebenza ngokubonakalayo. Kwiprofayili yeradial ye-impeller, ngokubanzi ikufutshane noxande, kwaye yayingaphantsi kwinqwelomoya ethe nkqo isebenzisa indawo yokujikeleza ye-axial yetywina yangaphambili, uyilo oluqhelekileyo lwempompo yempompo yesiqingatha somjikelezo, okanye isetyhula, eyenziwe kowona buchule buphezulu kufutshane nendawo uluhlu olubanzi lwexabiso elincinci lokunxiba kunye nokukrazula. Xa kufuneka amasuntswana amakhulu okuhambisa okuqinileyo, ngokuqhelekileyo kukhulu, ububanzi benombolo ye-impeller evaliweyo eyakhelwe ngaphakathi iyancitshiswa ibe ngamaqhekeza angama-2-3, kwisiseko sokuphucula ukunxiba kwempompo, ukusebenza kwempompo ye-hydraulic kunedigri eyahlukileyo yokunciphisa. .
Impompo eslurry vice impeller shaft seal ukupakisha itywina, itywina, itywina lomatshini.
I-1, i-slurry pump ukupakisha itywina kukuxhomekeka ngokwemiqathango yokuqina kunye nefuthe elithambileyo lokutywinwa phakathi kokupakisha kunye nomkhono we-shaft, ukupakisha itywina kunye ne-shaft yokutywina i-shaft yamanzi yokutywina uxinzelelo lwamanzi kufuneka ludlule uxinzelelo lwe-slurry pump outlet ye-1.5 kg, indlela yokutywina isetyenziswa ngokubanzi. kwindawo yokunxiba, iwasha yamalahle.
I-2, impompo eludaka itywina ngomatshini, i-friction play isiphumo sokutywinwa kweendawo eziguqukayo kunye ne-static ring ekufutshane yahlulahlulwe ibe yitywina yomatshini ngaphandle ngaphandle kohlobo lwesitofu samanzi sotywino lomatshini, uhlobo lwesitofu samanzi okuhlamba kwisitywina somatshini, uhlobo lwesitofu samanzi sotywino lomatshini. . Akukho luhlobo lwesitofu samanzi olutywiniweyo aludingi ukongeza amanzi okutywinwa kwe-shaft, ubomi benkonzo malunga neeyure ezingama-4000; Ngaphandle kokugungxula uhlobo lwenaliti yamanzi mechanical seal kunye shaft seal amanzi shaft itywina uxinzelelo lwamanzi 1.5 kg, ubomi benkonzo malunga 6000 iiyure; Uhlobo lwesitofu samanzi ukuhlamba itywina ngoomatshini kunye namanzi okutywinwa kweshaft afunekayo, uxinzelelo lwamanzi lwe-shaft lokutywina kunoxinzelelo lwempompo eludaka lwe-1.5 kg, ubomi benkonzo malunga neeyure ezingama-8000.
I-3, i-vice impeller ye-slurry pump seal iveliswa yi-vice impeller pressure seal effect, imfuno ye-slurry pump flow back back pressure ingadluli i-15% ye-slurry pump outlet pressure, xa umsebenzisi wokunqongophala kwamanzi kweli tywina.
