ʻAno liʻiliʻi BOP Annular
Hiʻona
1) E hoʻohana i ka ʻāpana paʻi liʻiliʻi a hoʻopili ʻia ke poʻo o BOP a me ke kino e nā poloka latch.
2) Hoʻohana ka BOP dynamic seal i ke apo lehelehe e hōʻemi i ka ʻaʻahu o ke apo sila a hōʻoia i ka sila hilinaʻi.
3) ʻO ka piston a me ka ʻāpana packing wale nō ke neʻe nei i nā ʻāpana, kahi e hōʻemi pono ai i ka wahi ʻaʻahu a pōkole i ka manawa mālama a hoʻoponopono.
4) Pono nā mea metala a pau e pili ana me nā wai punawai i nā koi o NACE MR 0175 no ka lawelawe ʻawaʻawa.
5) Hoʻomaʻamaʻa ke kaomi maikaʻi i ka hoʻopaʻa ʻana.

Hōʻike kēia huahana i kahi sila lehelehe me ka hiki ke hoʻopaʻa iā ia iho no ka hoʻonui ʻana i ka hilinaʻi. Loaʻa iā ia kahi lua i loko o ka piston no ka hoʻāʻo ʻana e ana i ke ola o ka lāʻau. Hoʻopaʻa ʻia ka pilina paʻa maʻamau i ka pilina paʻa, ʻoiai ke koʻikoʻi o ka pūpū a me ka hoʻokomo pono ʻana. ʻO kona mau pistons luna he ʻano cone, ka hopena i kahi anawaena liʻiliʻi o waho o ka huahana. Eia kekahi, ua lako ka ʻili friction me kahi pā abrasion proof e pale ai i ke poʻo a maʻalahi ke hoʻololi.
