Mofuta oa Taper Annular BOP
Sebopeho
1) Sebelisa yuniti ea ho paka e tapered le hlooho ea BOP le 'mele li hokahane ka li-latch blocks.
2) Setiiso se matla sa BOP se nka selikalikoe sa tiiso se bōpehileng joaloka molomo ho fokotsa ho roala ha reng ea tiiso le ho netefatsa ho tiisoa ho ka tšeptjoang.
3) Feela piston le sehlopha sa ho paka ke likarolo tse tsamaeang, tse fokotsang ka katleho sebaka sa ho roala le ho khutsufatsa nako ea tlhokomelo le ho lokisa.
4) Lisebelisoa tsohle tsa tšepe tse kopaneng le maro a seliba li tla fihlela litlhoko tsa NACE MR 0175 bakeng sa ts'ebeletso e bolila.
5) Khatello ea seliba e thusa ho tiisa.
Tlhaloso
Sehlahisoa sena se na le sekoaelo sa molomo se nang le bokhoni ba ho itšireletsa bakeng sa ho tšepahala ho ntlafetseng. E na le bore ka piston bakeng sa tlhahlobo ea stroke ho lekanya bophelo ba rabara. Khokahano ea poleiti ea claw e tiisa khokahano e tšepahalang, esita le khatello ea khetla le ho kenya tšebetsong habonolo. Lipiston tsa eona tse ka holimo li na le sebōpeho sa cone, e leng se etsang hore ho be le bophara bo bonyenyane ka ntle ba sehlahisoa. Ho feta moo, bokaholimo ba likhohlano bo na le poleiti ea bopaki ba abrasion ho sireletsa hlooho mme ho bonolo ho e khutlisa.
