Kana Pombi Yatanga, Tinofanira Kuvhara Ivhavha Yekubuda Kana Kuti Kwete?

Kazhinji, tanga iyopombi yecentrifugal, maererano nekutsanangurwa kunofanira kuva, yekutanga pombi yekamuri yakazadzwa nepakati, kuvhara valve yekubuda, uye wozarurapombi, chinangwa ndeichi: kune rumwe rutivi kudzivirira kutanga kwezvino kukuvadza kwakanyanya kune motokari;Kune rumwe rutivi, kudzivirira kurasikirwa kwekukurumidza kwekumanikidzwa mushure mekutangapombi, zvichiita kutipombicavitation.Asi matambudziko mazhinji haagone kujekeswa!

Nokuda kwekuyerera uye musoro wakadererapombi, kuvhara kana kusavhara valve yekubuda haisi dambudziko.

For hombepombi, iyo yekubuda inowanzovhurwa zvishoma kudzivirira kusiyana kwepakati pakati pepamberi neshure kwevhavha mushure mekutanga, uye vheji yekubuda haisi nyore kuvhura, saka kuvhura kwevhavha yekubuda kunovhurwa zvishoma.

Vamwecentrifugal pombiichavhura zvishoma vharafu yekubuda nekuda kwekupisa uye zvimwe zvinodiwa.

Kana iri nekusveta, kuvhara zvakakwana valve yekubuda, uye wozovhura vheji (kwete self-priming pump), asi zvakare vhura pombi yekupedza vharafu.

Kune mamwe mamiriro akakosha, vharafu yekubuda haigone kuvhurwa, semuenzaniso, propylene yemvura, kana vheji yekubuda ikavhura, propylene inoputika, pombi haizokwanise kumanikidza, saka inofanira kuvharwa kutanga, kupomba uye ipapo kurumidza kuvhura vharuvhu yekubuda nayo.

Zviri pamusoro apa mapombi ecentrifugal.Kune mamwe marudzi emapombi, mamiriro acho ndeaya:

1. Kuyerera kukuru kwekutanga-up maitiro eaxial kuyerera pombi-yakazara yakazaruka valve kutanga-up

Iyo shaft simba yeaxial inoyererapombindiyo yakakura pane zero kuyerera mamiriro, inova 140 % ~ 200 % yeyakayerwa shaft simba, uye simba ndiro diki pane yakanyanya kuyerera mamiriro.Nokudaro, kuitira kuti uderedze kutanga ikozvino, maitiro ekutanga emagetsi e shaft anofanira kunge ari makuru ekuyerera kutanga (kureva, kuvhura zvakakwana valve kutanga).

2. Kutanga-up maitiro emusanganiswa-kuyerera pombi-yakazara yakazaruka valve kutanga-up

Iyo shaft simba rekusanganiswa-kuyererapombipa zero kuyerera mamiriro ari pakati pezviviri zviri pamusoropombi, inova 100 % ~ 130 % yesimba rakarongwa.Nokudaro, maitiro ekutanga epombi yakasanganiswa-inoyerera inofanirawo kuva pakati pezviviri zviri pamusoro apapombi, uye zviri nani kutanga nekuvhura yakazara valve.

3. Kutanga-up maitiro evortex pombi-yakazara yakazaruka valve kutanga-up

Iyo shaft simba revortexpombindiyo hombe pane zero kuyerera mamiriro, iri 130 % ~ 190 % yeyakayerwa shaft simba.Naizvozvo, zvakafanana neaxial kuyererapombi, maitiro ekutanga epombi yevortex inofanira kuva yakakura kuyerera kwekutanga-up (kureva, full valve start-up).
