Kev tawg-cov pov thawj centrifugal kiv cua tuaj yeem muab faib ua qhov tawg- pov thawj centrifugal kiv cua (GBL) thiab hmoov av tawg- pov thawj centrifugal kiv cua (GFBL) raws li qhov tawg- cov khoom pov thawj.
Lawv cov qauv code suav nrog cov ntaub ntawv xws li series, specifications, thiab kis txoj kev. Noj "BF4-72-4.5A" ua piv txwv, "BF" sawv cev rau kev tawg- pov thawj thiab corrosion-resistant, "4-72" sawv cev rau tus qauv, "No4.5" sawv cev rau lub impeller sab nraud txoj kab uas hla ntawm 450 mm, thiab "A" sawv cev rau lub direct-tsav. Kuj tseem muaj qhov zoo sib xws "B4-72" hom tawg-pov thawj centrifugal kiv cua.
Cov kev xaiv tseem ceeb suav nrog txoj kev sib kis, xws li hom A ncaj qha - tsav lub cev muaj zog, hom C siv tsav, thiab hom D txuas txuas, thiab lwm yam, thiab tseem tuaj yeem tsim tshwj xeeb raws li cov neeg siv khoom xav tau. Saib ntawm qhov kawg ntawm lub cev muaj zog, clockwise tig ntawm lub impeller yog txoj cai - tes tig, thiab counterclockwise rotation yog sab laug - tes rotation. Lub kaum sab xis yog feem ntau muaj nyob rau hauv yim txoj kev xaiv: 0 degree, 45 degree, 90 degree, 135 degree, 180 degree, 225 degree, 270 degree, thiab 315 degree.
