Casing centralizer, tseem hu ua pwm positioner, yog cov cuab yeej tshaj lij tsim los kho cov pwm casing uas tawm ntawm kev sib raug zoo hauv cov txheej txheem txhaj tshuaj molding, feem ntau yog ntsia rau ntawm pwm, siv rau qhov chaw thiab txoj cai ntawm cov pwm casing. Nyob rau hauv cov txheej txheem ntawm kev txhaj tshuaj molding, lub tes tsho pwm feem ntau tsis raug vim hnav, deformation lossis lwm yam laj thawj, yog tias tsis muab tso rau thiab ncaj nraim rau lub sijhawm, nws yuav ua rau muaj teeb meem xws li qhov sib txawv ntawm qhov sib txawv ntawm cov khoom txhaj tshuaj molded, deg tsis xws luag, cov khoom pov tseg, thiab lwm yam, thiab txawm cuam tshuam rau kev tsim khoom thiab cov khoom zoo.
Los ntawm kev txhim kho lub casing centralizer, qhov tseeb qhov chaw thiab ceev txoj cai ntawm cov pwm casing tuaj yeem pom tau, kom cov khoom loj hauv cov txheej txheem txhaj tshuaj molding yog qhov tseeb, qhov saum npoo yog du, thiab tsis muaj qhov tsis xws luag, thiab tib lub sijhawm, Cov khoom pov tseg tuaj yeem raug txo qis, kev tsim khoom thiab cov khoom raug tuaj yeem txhim kho, thiab cov khoom zoo tuaj yeem lav.
