Indlela yokukhetha iphampu kazibuthe ye-fluoroplastic

Iphampu kazibuthe ye-Fluoroplastic okwamanje iwuhlobo olusha lwephampu ye-fluoroplastic engagqwali, esetshenziswe kabanzi emikhakheni eminingi ngenxa  ukungavuzi .

Iphampu kazibuthe ye-fluoroplastic ayigcini nje ngokuvuza lapho idlulisa okuphakathi, kodwa futhi ithuthukisa ukusebenza kahle ngo-5.% ukuze 10% uma kuqhathaniswa nemodeli yakudala. Isakhiwo se-hydraulic esiklanywe ngokwemishini yoketshezi ethuthukisiwe kunciphisa ukusetshenziswa kwamandla ngo-10% uma kuqhathaniswa nemodeli yakudala. Namuhla ake sikhulume ngokuthi singakhetha kanjani uhlobo olufanele lwepompo ye-fluoroplastic magnetic.

Isisekelo sokukhethwa kwamaphampu kazibuthe e-fluoroplastic kufanele sisekelwe ekugelezeni kwenqubo, izidingo zokuphakelwa kwamanzi kanye ne-drainage, futhi kufanele kucatshangelwe ezicini ezinhlanu, okuyivolumu yokulethwa koketshezi, ukukhushulwa kwedivayisi, izakhiwo eziwuketshezi, ukwakheka kwamapayipi nezimo zokusebenza, njll.

1. Izinga lokugeleza lingenye yedatha ebalulekile yokusebenza yokukhethwa kwepompo, ehlobene ngokuqondile namandla okukhiqiza kanye namandla okulethwa kwayo yonke idivayisi. Isibonelo, ekuklanyweni kwenqubo yesikhungo sokuklama, amazinga amathathu okugeleza amaphampu avamile, amancane namakhulu angabalwa. Lapho ukhetha ipompo, ukugeleza okuphezulu kuthathwa njengesisekelo futhi ukugeleza okuvamile kucatshangelwa. Uma kungekho ukugeleza okukhulu, ngokuvamile izikhathi ezingu-1.1 ukugeleza okujwayelekile kungathathwa njengokugeleza okuphezulu.

2. Ukuphakamisa okudingwa uhlelo lokufaka kungenye idatha yokusebenza ebalulekile yokukhethwa kwamaphampu e-fluoroplastic. Ngokuvamile, ilifti idinga ukukhuliswa ngo-5% -10% ukuze ukhethe imodeli.

3. Izakhiwo eziwuketshezi, okuhlanganisa igama le-liquid medium, izakhiwo ezibonakalayo, izakhiwo zamakhemikhali nezinye izakhiwo. Izakhiwo ezibonakalayo zihlanganisa izinga lokushisa c density d, viscosity u, okuqinile kuyizinhlayiyana ububanzi nokuqukethwe kwegesi phakathi nendawo, njll., okuhlobene nenhloko yesistimu, igesi ephumelelayo Ukubalwa kwezinsalela zokugqwala kanye nohlobo lwephampu olufanele: Izakhiwo zamakhemikhali ikakhulukazi zibhekisela ku ukugqwala kwamakhemikhali kanye nobuthi be-liquid medium, okuyisisekelo esibalulekile sokukhetha impahla yepompo kanye nohlobo lwe-shaft seal.

4. Izimo zesakhiwo sepayipi lesistimu yedivayisi zibhekisela ekuphakameni kokulethwa koketshezi, ibanga lokulethwa, isiqondiso sokudiliva, enye idatha efana neleveli yoketshezi ephansi ohlangothini lokumunca, ileveli ephezulu yoketshezi ohlangothini olukhiphayo, kanye nokucaciswa kwamapayipi kanye nawo. ubude, impahla, ukucaciswa kokufakwa kwamapayipi, kanye nenani njll., ukuze kwenziwe ukubalwa kwekhanda lekama kanye nokuhlola kwe-NPSH.

5. Kunezimo eziningi zokusebenza, ezifana nokusebenza kwe-liquid T egcwele isitimu 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 iphampu kazibuthe Ilungisiwe noma iyasuswa.
