API 7-1 4145 & Kola Yobowola Yopanda Magetsi

Kufotokozera Kwachidule:

Chokolera cha Drill chimapangidwa kuchokera ku chitsulo chosinthidwa cha AISI 4145H chozimitsidwa ndi chofewa ndipo chimatenthedwa kutalika kwake konse kuti chikhale cholimba komanso cholimba. Mayeso okhwima a zitsulo amachitidwa motsatira zomwe zafotokozedwa kuti atsimikizire kuti kutentha kumapanga kuuma kofanana komanso kwakukulu kudzera mu kuya kwa bala.

Landrill imapereka makola obowolera mu muyezo ndipo amazungulira kuyambira 3-1/8” OD mpaka 14” OD motsatira malangizo a API, NS-1 kapena DS-1.

Kolala yobowola yamba ndi gawo lozungulira, pakati pake pali dzenje la madzi, makulidwe a khoma ndi akulu, nozzle ndi yaying'ono, kulemera kwa kutalika kwa unit iliyonse ndi kwakukulu kuposa kukula kwa chitoliro chobowola pafupifupi nthawi 4-5. Kolala yobowola yambiri imakonzedwa mwachindunji pa thupi la chitoliro, koma ena amagwiritsanso ntchito cholumikizira chosinthidwa.

Kolala yobowola yozungulira ndi mtundu wa chida chobowola mafuta. Mtundu uwu wa kolala yobowola umatha kuletsa kutsekeka kwa mphamvu yosiyana ya zida panthawi yobowola. Mizere yozungulira imalola matope kuyenda momasuka kuzungulira kolala yobowola kuti agwiritse ntchito mphamvu yolinganiza kuti apewe kutsekeka kuti apewe kutsekeka kwa mphamvu yosiyana. Malo olumikizirana ndi khoma la chitsime amatha kudulidwa kuti achepetse kuthekera kopanga kutsekeka kwa mphamvu yosiyana.

Malo olumikizirana ndi khoma la chitsime amatha kudulidwa kuti achepetse kuthekera kopanga kutsekeka kwa mphamvu yosiyana. Kulemera kwa kolala yozungulira yobowola ndi 4-6% yochepera kuposa ya kolala yozungulira yobowola.

Kola Yobowola Yopanda Maginito: Kola Yobowola Yopanda Maginito imapangidwa kuchokera ku zipangizo za kola yobowola yopanda maginito yokhala ndi mphamvu zochepa pophatikiza kusanthula kwa mankhwala ndi njira yozungulira yopangira nyundo yokhala ndi mphamvu zochepa zamaginito. Tikhoza kupereka kutalika kuyambira mamita 10 mpaka 42 ndi mainchesi akunja kuyambira mamita 31/8 mpaka 11.
