Sucker Rod Centralizer
Whakatakotoranga Hua
1.Sucker rod centralizer Ko te momo taputapu downhole e papu ana pai anti-abrasion, he mea tino pai mo te papu pai me te pai aronga i runga ake o te ngote tokotoko te pito waenganui, i raro i te pito waenganui o te ngote tokotoko , te tinana tokotoko ki te nylon He pai ake te mahi a centralizer.
Ka neke whakarunga, heke iho te rakau ngote i roto i te ngongo, na te rerekeetanga o te rakau ngote, te rakau me te pakitara ngongo hinu he ngawari ki te hanga waku, ka ngawari te whati o te rakau ngote, he kaha te ngawari o te whakangao, ka pa ki te ngongo. Ka taea e te pakitara te whakaiti i te waku o te rakau me te ngongo, ka taea te whakanui ake i te oranga o te waahanga pupuhi.Kei te hono te centralizer ki te rakau ngote, he nui ake te diameter o waho o te centralizer i te hono i te diameter o waho, kia taea ai te mahi o te pokapū.Ko te pokapū he mea hanga mai i nga mea kaha-kaha, ka pa ki te ngongo ki te whakaiti i te abrasion ki te whakatutuki i te kaupapa o te anti-abrasion.
