Indlela yokukhetha iphampu yamakhemikhali?

Isikhathi: 2022-12-12


Izindawo ezihlukene, imidiya ehlukene, izinto ezihlukahlukene ... Kubonakala sengathi akulula kakhulu ukukhetha iphampu yamakhemikhali efanele. Iphampu engalungile ingalimaza imishini okungenani, futhi ibangele izingozi noma ngisho nezinhlekelele ezimbi kakhulu!


Namuhla i-Shuangbao izokwethula namuhla ulwazi mayelana nokukhetha uhlobo olusekelwe ekuhlangenwe nakho kwesikhathi esidlule kwezohwebo, ngethemba lokuthi izosisiza thina basebenzi bamakhemikhali.

Izimiso zokukhetha iphampu yamakhemikhali:
   1. Yenza uhlobo nokusebenza kwepompo ekhethiwe kuhlangabezane nezidingo zemingcele yenqubo njengokugeleza kwedivayisi, ukuphakamisa, ukucindezela, izinga lokushisa, ukugeleza kwe-cavitation, nokudonsa.
   2. Isidingo sokuhlangabezana nezidingo zezici ezimaphakathi.
   Izidingo zezici ezimaphakathi kufanele zihlangatshezwe. Kumaphampu adlulisa imidiya evuthayo, eqhumayo, enobuthi noma ebalulekile, izigxivizo ze-shaft ezinokwethenjelwa noma amaphampu angavuzi ayadingeka, njengamaphampu adonsa ngozibuthe (awekho ama-shaft seal, ukudluliswa okukodwa kozibuthe okungaqondile). Kumaphampu anemidiya eqala ukugqwala, izingxenye ze-convection kumele zenziwe ngezinto ezimelana nokugqwala, njengamaphampu amelana nokugqwala e-fluoroplastic. Kumaphampu adlulisa imidiya equkethe izinhlayiya eziqinile, izingxenye ze-convection zidingeka ukuthi zenziwe ngezinto ezingagugi, futhi uphawu lwe-shaft kufanele luwashwe ngoketshezi oluhlanzekile uma kunesidingo.
   3. Ukuthembeka okuphezulu komshini, umsindo ophansi nokudlidliza.
   4. Cabangela izindleko zokufaka zokuthenga iphampu ngokugcwele.
   Izimiso, izakhiwo zangaphakathi, nezingxenye zamanye amaphampu ziyefana, futhi umehluko omkhulu ubonakala ekukhethweni kwempahla, ukwakhiwa kanye nekhwalithi yezingxenye. Ngokuhlukile kweminye imikhiqizo, umehluko wezindleko zezingxenye zephampu ubaluleke kakhulu, futhi igebe lentengo lamakhulu noma izinkulungwane zezikhathi libonakala ekusebenzeni nasekuphileni kwesevisi yomkhiqizo.

 
Isisekelo sokukhetha amaphampu amakhemikhali:
   Isisekelo sokukhethwa kwamaphampu amakhemikhali kufanele sisekelwe ekugelezeni kwenqubo, izidingo zokuphakelwa kwamanzi kanye nokugeleza kwamanzi, futhi kucatshangelwe ezicini ezinhlanu, okuyivolumu yokulethwa koketshezi, ukuphakamisa, izakhiwo eziwuketshezi, ukwakheka kwamapayipi, nezimo zokusebenza.
   1. Ithrafikhi
   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. Inhloko
   Ikhanda elidingekayo yisistimu yokufaka enye idatha ebalulekile yokusebenza yokukhethwa kwepompo. Ngokuvamile, ikhanda lidinga ukukhuliswa ngo-5% -10% ukuze ukhethe imodeli.
   3. Izakhiwo eziwuketshezi
   Izakhiwo eziwuketshezi, okuhlanganisa igama eliphakathi nendawo eliwuketshezi, izakhiwo ezibonakalayo, izakhiwo zamakhemikhali nezinye izakhiwo, izakhiwo ezibonakalayo zifaka izinga lokushisa elingu-c density d, viscosity u, ububanzi bezinhlayiyana eziqinile kanye nokuqukethwe kwegesi phakathi nendawo, njll., okuhlobene nenhloko yohlelo, I-cavitation ephumelelayo Ukubalwa kwenani kanye nohlobo lwepompo olufanele: izakhiwo zamakhemikhali, ikakhulukazi zibhekisela ekugqwaleni kwamakhemikhali kanye nobuthi be-liquid medium, okuyisisekelo esibalulekile sokukhetha izinto zokupompa kanye nohlobo lwe-shaft seal.
   4. Izimo zokuhlela amapayipi
   Izimo zesakhiwo sepayipi lesistimu yedivayisi zibhekisela ekuphakameni kokulethwa koketshezi, ibanga lokulethwa, isiqondiso sokuletha, enye idatha efana neleveli yoketshezi ephansi ohlangothini lokumunca, ileveli ephezulu yoketshezi ohlangothini lokuphuma, kanye nokucaciswa kwepayipi kanye ubude bazo, impahla, ukucaciswa kokufakwa kwamapayipi, ubungako, njll. Ukuze kwenziwe ukubalwa kwekhanda lekamu kanye nesheke le-NPSH.
   5. Izimo zokusebenza
   Kunezimo eziningi zokusebenza, njengokusebenza kwe-liquid T egcwele umhwamuko wengcindezi P, ingcindezi eseceleni yokumunca i-PS, ingcindezi yesitsha eseceleni yokukhipha i-PZ, ukuphakama, izinga lokushisa elizungezile noma ngabe ukusebenza kuphakathi noma kuyaqhubeka, nokuthi indawo yepompo imisiwe noma kungenzeka.
