S / S icala lokuhlukanisa iphampu ibhekwa ngokuyinhloko kusukela kugeleza, ikhanda, izakhiwo eziwuketshezi, ukwakheka kwamapayipi nezimo zokusebenza. Nazi izixazululo.

Izakhiwo eziwuketshezi, okuhlanganisa igama eliwuketshezi eliphakathi nendawo, izakhiwo ezibonakalayo, izakhiwo zamakhemikhali nezinye izakhiwo, izakhiwo ezibonakalayo zifaka izinga lokushisa elingu-c density d, viscosity u, ububanzi bezinhlayiyana eziqinile nokuqukethwe kwegesi phakathi nendawo, njll., okubandakanya inhloko yohlelo, I-cavitation esebenzayo eyinsalela Ukubalwa kwenani kanye nohlobo lwepompo olufanele: izakhiwo zamakhemikhali, ikakhulukazi ibhekisela ekulimaleni kwamakhemikhali kanye nobuthi be-liquid medium, okuyisisekelo esibalulekile sokukhetha ukuhlukana. iphampu yecala impahla nokuthi yiluphi uhlobo lwe-shaft seal okufanele ukhethe.

Ukugeleza kungenye yedatha yokusebenza ebalulekile yokukhethwa kwephampu, ehlobene ngokuqondile namandla okukhiqiza kanye namandla okudlulisa alo lonke idivayisi. Isibonelo, ekuklanyweni kwenqubo ye-Design Institute, amazinga okugeleza avamile, amancane kanye naphezulu kakhulu epompo angabalwa. Uma ukhetha ipompo evulekile yensimbi engenasici, thatha ukugeleza okuphezulu njengesisekelo futhi ucabangele ukugeleza okuvamile. Uma kungekho ukugeleza okuphezulu, imvamisa izikhathi ezi-1.1 ukugeleza okujwayelekile kungathathwa njengokugeleza okuphezulu.

Inhloko edingekayo yisistimu enye idatha ebalulekile yokusebenza yokukhethwa kwepompo. Ngokuvamile, ikhanda kufanele likhuliswe ngo-5% -10% wemajini ukuze kukhethwe.

Ngokuvumelana nokuhlelwa kwedivayisi, izimo zezwe, izimo zezinga lamanzi, nezimo zokusebenza, nquma ukukhethwa kwamaphampu avundlile, aqondile kanye nezinye izinhlobo (amapayipi, angaphansi kwamanzi, angaphansi kwamanzi, angavimbeli, azibambele mathupha, igiya, njll. ).

Izimo zesakhiwo sepayipi lesistimu yedivayisi zibhekisela ekuphakameni kokulethwa koketshezi, ibanga lokulethwa koketshezi, kanye nendlela yokulethwa koketshezi, njengeleveli yoketshezi ephansi kakhulu ohlangothini lokumunca kanye neleveli ephezulu kakhulu yoketshezi ohlangothini lokuphuma, kanye nokunye. idatha efana nokucaciswa kwamapayipi nobude bawo, izinto zokwakha, imininingwane yokufakwa kwamapayipi, amanani, njll., Ukuze kwenziwe ukubalwa kwekhanda lekama-tie kanye nesheke le-NPSH.

Kunezimo eziningi zokusebenza, ezifana nokusebenza kwe-liquid T, i-saturated steam force P, i-suction side pressure PS (absolute), i-dicharge side container pressure PZ, ukuphakama, izinga lokushisa elizungezile, noma ngabe ukusebenza kuphakathi noma okuqhubekayo, kanye nesimo sepompo. ilungisiwe noma cha. esikhiphekayo.

Kumaphampu awuketshezi ane-viscosity enkulu kuno-20mm2/s (noma ukuminyana okukhulu kuno-1000kg/m3), kuyadingeka ukuguqula ijika lesici lepompo lokuhlola amanzi libe ijika lokusebenza kwe-viscosity (noma ngaphansi kokuminyana), ikakhulukazi ukusebenza kokumunca namandla okufaka. Yenza izibalo ezibucayi noma iziqhathaniso.

Nquma inombolo nezinga lokulinda lamaphampu e-S/S okumunca kabili okuhlukanisayo. Ngokuvamile, ipompo eyodwa kuphela isetshenziselwa ukusebenza okujwayelekile, ngoba iphampu eyodwa enkulu ilingana namaphampu amabili amancane asebenza ngokufana (okusho ukuphakama nokugeleza okufanayo), futhi iphampu enkulu inokusebenza okuphezulu. Kumaphampu amancane, ngokombono wokonga amandla, kungcono ukukhetha iphampu eyodwa enkulu esikhundleni samaphampu amabili amancane, kodwa ezimweni ezilandelayo, amaphampu amabili angabhekwa ngokufanayo: izinga lokugeleza likhulu, futhi iphampu eyodwa ayikwazi ukufinyelela. leli zinga lokugeleza. Kumaphampu amakhulu adinga isilinganiso esingu-50% sokulinda, amaphampu amabili amancane angashintshwa ukuze asebenze, amabili alindile (amathathu esewonke).
