Dhuumaha balaadhinta kulaylka waa hab farsamaynta tuubada birta ah ee habka gaarka ah waa balaadhin kulul isticmaalka hawo-mareenka ama habab farsamaysan oo ku boorinaysa tuubada birta ee gidaarka birta oo ay weheliso tikniyoolajiyadda farsamaynta cadaadiska dibadda ee dilatation radially. Macnaha makaanikada marka loo eego hababka haydarooliga, aaladaha, fudud iyo awooda ka badan ee hormuudka adduunka ee is-dhowr-caliber-caliber tolled ballaaran kontoroolka habka tuubooyinka ayaa la doortay.

Habka habaynta ee tuubada ballaadhinta kulaylka, waa tuubada dhexroor yar oo farsamaysa tuubo dhexroor weyn ah. Dhuumaha balaadhinta kulaylka guryaha qalabka birta ee kulul marka loo eego xoogaa ka yar. Ku xaddidan tuubooyinka birta caadiga ah ee birta ah ee birta ah waa xaddidan tahay, marka loo eego baahida macaamiisha dhamaadka-macmiilka tuubada ballaarinta kuleylka si ay u dhalatay, tuubada ballaarinta kulaylka Qaabka caadiga ah ee caadiga ah waa mid aad u weyn, badanaa wuxuu ku saleysan yahay baahida macaamiisha iyo wax soo saarka, tuubada ballaarinta kuleylka waa, waxaan inta badan waxay yiraahdaan balaadhinta kulaylka ee tuubada, cufnaanta waa mid aad u hooseeya, laakiin gaabinaysa tuubo bir ah oo xooggan, (tuubo bir ah oo aan lahayn) waxaa loo tixraaci karaa balaadhinta kulaylka.
