Type U VariabIe Bore Ram Assembly
Tsanangudzo:
Yedu Type U variable bore rams (VBR) zvisimbiso zvinogona kushandiswa pamasaizi akati wandei epombi kana hexagonal Kelly. Iyo variable bore ram packer ine simbi inosimbisa inoisa. Zvinopinza zvinotenderedza mukati kana makondohwe akavharwa saka simbi inopa tsigiro yerabha inonamira papombi. Gondohwe rinochinjika rinogona kushandiswa kuvhara madhayamita akasiyana etambo yepombi. Gondohwe rinochinjika rinoumbwa negondohwe rakasiyana-siyana, chisimbiso chepamusoro, uye chisimbiso chemberi chakasiyana. Kuiswa kweiyo inoshanduka RAM muBOP kwakafanana neyakajairika RAM, haifanire kushandura chero chikamu cheBOP. Kuwedzera kune tsananguro yakapihwa, mhando yeU Variable Bore Rams (VBR) inoratidza kuchinjika uye kusimba mumabasa ekuchera. Dhizaini yayo inochinjika inoibvumira kuvhara masaizi akati wandei epombi kana hexagonal Kelly, ichiratidza kugona kwayo uye kushandiswa kwakasiyana-siyana kwekuchera.
Pakati peVBR pane simbi inosimbisa inoisa inotenderera mukati kana yavharwa makondohwe. Ichi chimiro chitsva chinosimbisa kubata kwerabha papombi, zvichiita kuti chisimbiso chakasimba uye chinoshanda zvisinei nedhayamita yepombi.
Iyo mhando yeU VBR gungano inosanganisira gondohwe rakasiyana, chisimbiso chepamusoro, uye chinoshanduka chemberi chisimbiso, zvese zvakagadzirirwa kusimba zvakanyanya uye kuita. Kureruka kwekuisa kunowedzera kukwezva kwayo, neVBR inobatanidza zvisina mutsindo mumaseti aripo eBOP pasina kudiwa kwekugadziridzwa.
Pamusoro pezvo, iyo U VBR inoratidza kuramba kunoshamisa kune yakanyanya kudzvanywa uye tembiricha, nekuda kwekuvaka kwayo kwakasimba. Kusimba uku, kwakasanganiswa nekusarudzika kwayo mukusunga madhayamita epombi akasiyana, kunoomesa chimiro cheU VBR sechinhu chakakosha chekubudirira kutonga matsime.
