Single/biyu mataki tsaga famfo (API610/BB2)

1. Jikin famfo: Jikin famfo yana ɗaukar tsarin ɗakin gungura biyu don rage ƙarfin radial, rage nauyin shaft, da tsawaita rayuwar sabis na bearings; shigarwa na tsakiya da tsarin tallafi a ƙarshen duka biyu na iya inganta aikin famfo saboda hawan zafi a ƙarƙashin yanayin zafi mai girma. Tsayin yana iya haifar da fadadawa da nakasar jikin famfo; za a iya daidaita mashigin ruwa da mashigar famfo ta hanyoyi daban-daban don sauƙaƙe tsarin bututun mai amfani;

. Ana amfani da gasket na ƙarfe mai aminci sosai don rufe jikin famfo da murfin famfo, yana sauƙaƙa jigilar matsanancin zafin jiki, mai guba, mai cutarwa, da sauƙin watsawa;

3. Impeller: Tsarin mataki ɗaya gabaɗaya yana amfani da injin tsotsa sau biyu don rage NPSH na famfo da rage farashin shigarwa na na'urar. A lokaci guda, mai tsotsa sau biyu yana iya daidaita ƙarfin axial da aka samar da kansa: tsarin matakai biyu gabaɗaya yana amfani da tsotsa sau biyu na mataki na farko da na biyun. Tsarin tsotsa guda ɗaya na matakin farko da tsotsa sau biyu na farko na iya yin la'akari da buƙatun cavitation na famfo. Mai sakawa na biyu yana amfani da ramin ma'auni don daidaita ma'aunin axial, kuma ragowar ƙarfin axial yana ɗauka ta wurin ɗaukarsa. Don yanayin aiki tare da ƙananan buƙatu akan aikin cavitation da ingantaccen aiki, ana iya yin la'akari da tsarin tsotsa guda biyu na baya-baya ko fuska da fuska;

4. Shaft: Yana ɗaukar ƙira mai tsauri tare da ƙananan karkatarwa. Idan diamita na shaft ya fi 60mm, an tsara shi a matsayin tsayin daka mai ma'ana, wanda ke sauƙaƙe shigarwa da ƙaddamar da haɗin gwiwa, bearings da hatimi;

5. Bearings da lubrication: The bearings yi amfani da mai-zobe kai mai jujjuya bearings ko zamiya hali tsarin bisa ga shaft ikon da gudun. Lokacin da aka zaɓi tsarin jujjuyawar, ƙarshen tuƙi yana amfani da ƙwallon ƙafa mai zurfi don samar da goyon baya na radial, kuma ƙarshen da ba a sarrafa shi yana sanye da nau'ikan ƙwallon ƙwallon ƙafa na kusurwa don iyakance motsin axial na rotor kuma a lokaci guda yana samar da radial. goyon baya; lokacin da aka yi amfani da ƙuƙwalwar zamewa , ƙwanƙwarar ƙwanƙwasa na radial a ƙarshen biyu suna taka rawar goyon baya na radial, kuma an shirya nau'i-nau'i na ball bearings na kusurwa a bayan radial bearing a ƙarshen ba tuki ba don iyakance motsi na axial na rotor;

6. Mechanical hatimi: Tsarin hatimi ya dace da buƙatun API682 4th Edition "Centrifugal Pump and Rotary Pump Seling System" da Sinopec kayan siyan ma'auni, kuma za'a iya daidaita su tare da nau'i daban-daban na rufewa, flushing, da kwantar da hankali.
