Shaffer Type Variable Bore Ram Assembly
Tsanangudzo:
Yedu mhando S variable bore rams (VBR) chisimbiso pane akati wandei saizi yepombi 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 kwekusiyana kweRAM muBOP kwakafanana negondohwe rakajairika, hazvidi kushandura chero chikamu cheBOP. mhando S Variable Bore Rams (VBR) inopa mhinduro ine simba yekuwana yakachengeteka uye yakachengeteka chisimbiso yakatenderedza akasiyana pombi saizi uye maumbirwo. Iyo inochinjika dhizaini uye inogadziridza chimiro cheVBR inobvumira kuchinjika kukuru uye kuita kwakasiyana-siyana mukushanda, zvichiita kuti ive yakakosha kuwedzera kune chero midziyo yekuchera.
Chimwe nechimwe chikamu cheVBR, kubva pasimbi yayo yekusimbisa inoisa kune yayo yemhando yepamusoro zvisimbiso, inogadzirwa zvine hungwaru kuti ive nechokwadi chekushanda kwakanyanya uye kusimba. Iwo ma packers, akasimbiswa nesimbi, anopa rutsigiro rwakasimba uye yakasarudzika yekuisa chisimbiso kugona, kuve nechokwadi chekutendeseka zvakanaka kunyangwe pasi pemamiriro ekumanikidza.
Iko kureruka kweiyo VBR yekumisikidza maitiro inoiisa parutivi, ichipa isina musono kusanganisa mune iripo BOP setups pasina kudiwa kwechero shanduko. Izvi zvinoshandura mukudzikira nguva uye kuwedzera kushanda zvakanaka.
Uyezve, iyo mhando S VBR inoratidza kusimba kwakasimba kunopesana nemamiriro ekuchera. Magadzirirwo ayo anoigonesa kuvhara nemadhayamita akasiyana-siyana etambo yepombi, ichipa kuchinjika uye kutonga kwakavimbika munzvimbo dzakasimba dzekuchera. Uku kuchinjika kunoisa mhando S VBR sechinhu chakakosha mukuchengetedza kuchengetedzwa kwekushanda uye kugona.
