S / S ityala lokwahlula impompo iqwalaselwa ikakhulu ukusuka ekuhambeni, intloko, iipropati zolwelo, ukwakheka kwemibhobho kunye neemeko zokusebenza. Nazi izisombululo.

Iipropati zolwelo, kubandakanywa igama eliphakathi kolwelo, iipropati ezibonakalayo, iipropati zeekhemikhali kunye nezinye iipropati, iipropati ezibonakalayo ziquka ubushushu be-c density d, i-viscosity u, i-particle diameter eqinileyo kunye nomxholo wegesi phakathi, njl., ezibandakanya intloko yenkqubo, esebenzayo cavitation residual Ubungakanani ukubalwa kunye nohlobo impompo efanelekileyo: iipropati imichiza, ikakhulu ibhekisela ukudleka kwemichiza kunye netyhefu medium liquid, nto leyo isiseko esibalulekileyo ukukhetha ukwahlula. impompo yetyala impahla kunye noluphi uhlobo lwesitywina se-shaft ukukhetha.

Ukuhamba ngenye yedatha ebalulekileyo yokusebenza ekukhethweni kwempompo, ehambelana ngokuthe ngqo nomthamo wokuvelisa kunye nomthamo wokuhambisa isixhobo sonke. Ngokomzekelo, kwinkqubo yoyilo lweZiko loYilo, umgangatho oqhelekileyo, ubuncinci kunye nobuninzi bokuhamba kwempompo ingabalwa. Xa ukhetha umpompo ovulekileyo wensimbi engenasici, thatha ukuhamba okuphezulu njengesiseko kwaye uthathele ingqalelo ukuhamba okuqhelekileyo. Xa kungabikho ukuhamba okuphezulu, ngokuqhelekileyo amaxesha e-1.1 ukuhamba okuqhelekileyo kungathathwa njengobuninzi bokuhamba.

Intloko efunwa yinkqubo enye idatha ebalulekileyo yokusebenza ekukhethweni kwempompo. Ngokuqhelekileyo, intloko kufuneka yandiswe nge-5% -10% yomda wokukhethwa.

Ngokwelungiselelo lesixhobo, iimeko zomhlaba, iimeko zomgangatho wamanzi, kunye neemeko zokusebenza, misela ukukhethwa kweempompo ezithe tyaba, ezithe nkqo kunye nezinye (umbhobho, ukuntywila, ukuntywila, ukuntywila, ukungavimbeli, ukuzibamba, izixhobo, njl. ).

Iimeko zobeko lwemibhobho yesixokelelwano sesixhobo zibhekisa kumphakamo wonikezelo lolwelo, umgama wokuhanjiswa kolwelo, kunye nesalathiso sonikezelo lolwelo, njengenqanaba lolwelo elisezantsi kwicala lokufunxa kunye nenqanaba lolwelo liphezulu kwicala lokukhupha, kunye nokunye. idatha efana neenkcukacha zombhobho kunye nobude bazo, izixhobo, iinkcukacha zokufakelwa kwemibhobho, ubuninzi, njl., Ukuze kuqhutywe ubalo lwentloko ye-tie-comb kunye netshekhi ye-NPSH.

Zininzi iimeko zokusebenza, ezifana ukusebenza ulwelo T, amandla umphunga P ehlumayo, uxinzelelo ecaleni ukufunxa PS (absolute), ukukhupha uxinzelelo isikhongozeli ecaleni PZ, ukuphakama, ubushushu ambient, nokuba umsebenzi i intermittent okanye okuqhubekayo, kunye nendawo impompo. ilungisiwe okanye hayi. iyasuswa.

Kwiimpompo zolwelo ezine-viscosity enkulu kune-20mm2/s (okanye ingxinano enkulu kune-1000kg/m3), kuyafuneka ukuguqula igophe lephawu lempompo yovavanyo yamanzi ibe yigophe yokusebenza kwe-viscosity (okanye phantsi koxinaniso), ngakumbi ukusebenza kokufunxa kunye namandla egalelo. Yenza izibalo ezinzulu okanye uthelekiso.

Qinisekisa inani kunye nesantya sokulinda se-S/S seempompo zecala lokufunxa kabini. Ngokuqhelekileyo, ipompo enye kuphela isetyenziselwa ukusebenza okuqhelekileyo, kuba impompo enye enkulu ilingana neempompo ezimbini ezincinci ezisebenza ngokufanayo (ithetha ukunyuswa okufanayo kunye nokuhamba), kwaye ipompo enkulu inokusebenza okuphezulu. Kwiimpompo ezincinci, ukusuka kumbono wokulondoloza amandla, kungcono ukhethe impompo enye enkulu endaweni yeepompo ezimbini ezincinci, kodwa kwiimeko ezilandelayo, iipompo ezimbini zinokuthi ziqwalaselwe ngokufanayo: izinga lokuhamba likhulu, kwaye ipompo enye ayikwazi ukufikelela. lo mgangatho wokuhamba. Kwiimpompo ezinkulu ezifuna i-50% yezinga lokulinda, iimpompo ezimbini ezincinci zingatshintshwa ukuze zisebenze, ezimbini zokulinda (ezithathu zizonke).
