Uchungechunge lwe-HGL kanye ne-HGW olulodwa oluqondile kanyeamaphampu amakhemikhali avundlile esiteji esisodwazisekelwe kumaphampu amakhemikhali okuqala enkampani yethu. Sicabangela ngokugcwele ukucaciswa kwezidingo zesakhiwo samaphampu amakhemikhali ngesikhathi sokusetshenziswa, sisebenzise ulwazi oluthuthukisiwe lwesakhiwo ekhaya nakwamanye amazwe, futhi samukela amaphampu ahlukene. umgodi, isakhiwo sokuxhumanisa esibambayo, esinezici zesakhiwo esilula kakhulu, ukugxila okuphezulu, ukudlidliza okuncane, ukusetshenziswa okuthembekile, kanye nokugcinwa okulula. Kuyisizukulwane esisha sephampu yamakhemikhali yesigaba esisodwa esithuthukiswe ngobuhlakani.
Isicelo
Amaphampu amakhemikhali ochungechunge lwe-HGL ne-HGWingasetshenziswa ngezinga elithile embonini yamakhemikhali, ukuthuthwa kwamafutha, ukudla, iziphuzo, imithi, ukwelashwa kwamanzi, ukuvikelwa kwemvelo kanye namanye ama-asidi, ama-alkali, usawoti kanye nezinye izinhlelo zokusebenza ngokwezimo ezithile zokusetshenziswa zomsebenzisi. I-medium egqwalisayo, engenazo izinhlayiya eziqinile noma inani elincane lezinhlayiya, futhi inobuthi obufana namanzi. Akukhuthazwa ukusetshenziswa ezimweni ezinobuthi, ezivuthayo, eziqhumayo, noma ezigqwalisayo kakhulu.
(1) I-asidi ye-nitrikhi kanye nokusetshenziswa kwayo embonini ye-asidi ye-nitrikhi
Enqubweni yokukhiqiza i-nitric acid nge-oxidation ye-ammonia, i-nitric acid encibilikisiwe (50-60%) ekhiqizwa embhoshongweni wokumunca insimbi engagqwali iphuma phansi kombhoshongo iye ethangini lokugcina insimbi engagqwali, bese ithuthwa iye enqubweni elandelayo ngepompo yensimbi engagqwali. Naka izinga lokushisa eliphakathi nendawo kanye nengcindezi yokungena lapha.
(2) Ukusetshenziswa embonini ye-phosphoric acid kanye ne-phosphoric acid
Nge-asidi emsulwa, insimbi engagqwali ye-Cr13 imelana ne-asidi encibilikisiwe evuvukele kuphela, kanti insimbi engagqwali ye-chromium-nickel (Cr19Ni10) austenitic imelana ne-asidi encibilikisiwe evuvukele kuphela. Izinto ezingcono kakhulu ezimelana ne-phosphoric acid yinsimbi engagqwali ye-chromium-nickel-molybdenum (ZG07Cr19Ni11Mo2), njll.
Kodwa-ke, ngenqubo yokukhiqiza i-phosphoric acid, ukukhethwa kwezinto zephampu kuyinkimbinkimbi kakhulu ngenxa yezinkinga zokugqwala okubangelwa ukuba khona kokungcola ku-phosphoric acid, futhi kumele kuphathwe ngokucophelela.
(3) Ukusetshenziswa embonini ye-sodium chloride kanye nosawoti (amanzi ahlanzekile, amanzi olwandle, njll.)
Insimbi engagqwali ye-Chromium-nickel inezinga eliphansi kakhulu lokugqwala elilinganayo ngokumelene nezixazululo ze-sodium chloride ezingathathi hlangothi nezine-alkaline kancane, amanzi olwandle namanzi anosawoti ekushiseni okuthile kanye nokuhlushwa, futhi isetshenziswa kabanzi. Kodwa-ke, kufanele kuqashelwe ukuthi ukugqwala okuyingozi kwendawo ethile kungase kwenzeke kwezinye izimo.
Amaphampu ensimbi engagqwalizisetshenziswa kabanzi embonini yokudla ekuphatheni ukudla okune-brine nosawoti. Kodwa-ke, kufanele kuqashelwe izinkinga zokwakheka kwe-media crystallization kanye nezinkinga zokukhetha uphawu lwemishini.
(4) Ukusetshenziswa embonini ye-sodium hydroxide kanye ne-alkali
Insimbi engagqwali ye-Chromium-nickel austenitic ingamelana nokushisa kwe-sodium hydroxide ngaphansi kuka-40-50% kuya ku-80°C, kodwa ayimelani noketshezi lwe-alkali olunezinga eliphezulu lokuhlushwa kanye nokushisa okuphezulu.
Insimbi engagqwali ye-Chromium ifaneleka kuphela ezixazululweni ze-alkali ezisezingeni eliphansi lokushisa kanye nezinga eliphansi lokugxila.
Kumelwe kunakwe inkinga ye-crystallization ephakathi.
(5) Ukusetshenziswa ekuthuthweni kwamafutha
Kumelwe kunakwe ukujiya kwe-medium, ukukhethwa kwezingxenye zerabha, nokuthi ingabe imoto inezidingo ezingamelani nokuqhuma, njll.
(6) Ukusetshenziswa embonini yezemithi
Amaphampu ezokwelapha angahlukaniswa ngezigaba ezimbili ezilandelayo ngokuya ngendlela yokudiliva iphampu:
Uhlobo olulodwa amaphampu amanzi avamile, amaphampu amanzi ashisayo kanye namaphampu ohlelo lokuhlanza amanzi angcolile asetshenziswa kumaphrojekthi omphakathi, kanti olunye uhlobo amaphampu okuthutha izinqubo ezifana noketshezi lwamakhemikhali, izinto eziphakathi, amanzi ahlanzekile, ama-asidi nama-alkali.
Eyokuqala inezidingo eziphansi zamaphampu futhi ingaphathwa ngamaphampu asetshenziswa emishinini yamakhemikhali ejwayelekile, kanti eyesibili inezidingo eziphakeme zamaphampu. Amaphampu kumele ahlangabezane nezidingo zobuchwepheshe zamaphampu e-centrifugal asetshenziswa emishinini yezokwelapha.
(7) Ukusetshenziswa embonini yokudla neziphuzo
Embonini yokudla neziphuzo, le nto ayiboli noma ayiboli kancane, kodwa ukugqwala akuvunyelwe, futhi ubumsulwa bento esetshenziswayo buphezulu kakhulu. Kulokhu, kungasetshenziswa ipompo yensimbi engagqwali.
Izici zesakhiwo
1. Ukwakheka okuhlukaniswe ngezigaba komgodi wephampu walolu chungechunge lwamaphampu kugwema ngokuyisisekelo ukulimala kokugqwala komgodi wemoto. Lokhu kuqinisekisa ngokuphelele ukusebenza okuzinzile nokuthembekile kwesikhathi eside kwemoto.
2. Lolu chungechunge lwamaphampu lunesakhiwo somshafu wephampu esithembekile nesintsha. Iphampu eqondile ingasebenzisa kalula injini ejwayelekile yesakhiwo se-B5 ukushayela ngqo iphampu yamanzi, kanti iphampu evundlile ingasebenzisa kalula injini ejwayelekile yesakhiwo se-B35 ukushayela ngqo iphampu yamanzi.
3. Isembozo sephampu kanye nebhuleki yalolu chungechunge lwamaphampu kuklanywe njengezingxenye ezimbili ezizimele ezinesakhiwo esifanelekile.
4. Lolu chungechunge lwamaphampu lunesakhiwo esilula kakhulu futhi kulula ukulunakekela. Uma umshafu wephampu udinga ukushintshwa, kulula ukuwuhlukanisa nokuwufaka, futhi indawo obekwe kuyo inembile futhi ithembekile.
5. Umgodi wepompo kanye nomgodi wemoto walolu chungechunge kuxhunywe ngokuqinile nge-clamped coupling. Ubuchwepheshe obuthuthukisiwe nobunengqondo bokucubungula kanye nokuhlanganisa benza umgodi wepompo ube nokugxila okuphezulu, ukudlidliza okuphansi nomsindo ophansi.
6. Uma kuqhathaniswaamaphampu amakhemikhali avundlilengesakhiwo esijwayelekile, lolu chungechunge lwamaphampu avundlile lunesakhiwo esincane futhi isikhala sephansi leyunithi sincishisiwe kakhulu.
7. Lolu chungechunge lwamaphampu lusebenzisa umklamo omuhle kakhulu wemodeli ye-hydraulic. Ukusebenza kwephampu kuzinzile futhi kuyasebenza kahle.
8. Umzimba wephampu, isembozo sephampu, impeller kanye nezinye izingxenye zalolu chungechunge lwamaphampu zifakwa ngokunemba ngokufakwa kwezimali, ngokunemba okuphezulu, iziteshi zokugeleza ezibushelelezi kanye nokubukeka okuhle.
9. Izimbozo zephampu, imiphini, amabhuleki kanye nezinye izingxenye zalolu chungechunge lwamaphampu zisebenzisa imiklamo evamile futhi zingashintshana kakhulu.
