SOF/SOU Babban famfo matsa lamba (API610/OH2)

Tsarin OH2 famfo tsarin sarrafa sinadarin petrochemical shine a kwance, mataki-ɗaya, famfo centrifugal mai tsaga radially. Wannan jerin famfo yana da akwati daban don ɗaukar duk ƙarfin da aka yi akan mashin famfo kuma tabbatar da matsayin rotor. Ana shigar da famfo A kan tushe kuma an haɗa shi da direbansa ta hanyar haɗin gwiwa mai sassauƙa.

1. Jikin famfo: Jikin famfo yana ɗaukar ƙirar ƙirar ƙima. Fitar jiki na famfo ≥DN80 yana ɗaukar ƙirar hydraulic volute sau biyu, wanda ke daidaita ƙarfin radial zuwa mafi girma. An ƙera girman bangon bango bisa ga buƙatun API610. Jikin famfo Tallafin tsakiya na iya inganta yanayin zafi da jure babban nauyin bututun ƙarfe. The magudanar dubawa na famfo jiki ne welded da integrally flanged;

2. Abubuwan da aka haɗa: Abubuwan da aka haɗa (akwatin ɗaukar hoto, ɗaukar hoto, shaft, gland, murfin famfo, da sauransu) sun ɗauki tsarin cirewa gabaɗaya, wanda ke ba da damar dubawa da kula da famfo ba tare da motsa bututun shigarwa da fitarwa ba. Abubuwan da aka yi amfani da su suna ɗaukar tsattsauran ƙira, kuma babu wani shinge mai ɗaukar hoto a ƙarshen akwatin ɗamara;

3. Shaft: The shaft ne danda shaft tsarin, da stiffness index na famfo shaft ya gana da bukatun API61011 Shafi K. A lokaci guda, da impeller goro anti-reverse tsarin da aka soma don saduwa da bukatun on-site. yanayin aiki da inganta aminci da kwanciyar hankali na kayan aiki.

4. Axial Force balance: An ƙera zoben da ba za su iya jurewa ba a ɓangarorin biyu na impeller, kuma ana buɗe ramin ma'auni a ciki don yin matsin lamba a bangarorin biyu na ma'aunin kai, kuma bugun bugun yana ɗaukar ƙasa kaɗan. kaya.

5. Bearings da lubrication: Ƙaƙwalwar gaba (ƙusa kusa da kan famfo) yana amfani da ƙananan ƙwallon ƙafa mai zurfi, wanda kawai ke ɗaukar ƙarfin radial. Ƙaƙwalwar baya (ƙusa kusa da ƙarshen tuƙi) yana amfani da nau'i-nau'i na ball bearings na kusurwa (jeri na 73) ko nau'i-nau'i na nadi (jeri 31); bearings suna ɗaukar tsarin lubrication na zoben mai, kuma za'a iya zaɓar nau'in hatimi mai ƙarfi gwargwadon buƙatun mai amfani Ko hatimin labyrinth.

6. Mechanical hatimi: The sealing cavity size ya dace da API682 4th "Shaft Seal System for Centrifugal Pumps da Rotary Pumps", da kuma daban-daban nau'i na sealing, flushing, da kuma sanyaya mafita za a iya kaga.
