1.Sucker rod centralizer ndi mtundu wa zida zapansi zomwe zimapopa bwino anti-abrasion, ndizoyenera kupopera bwino komanso kuwongolera bwino komwe pamwamba pa sucker rod middle point, pansi pa point yapakati ya sucker rod, ndodo ya ndodo yokhala ndi nayiloni. centralizer imagwira ntchito bwino.
Ndodo yoyamwa imasunthira mmwamba ndi pansi mu chubu, chifukwa cha kusinthika kwa ndodo ya sucker, ndodo ndi khoma la chubu lamafuta ndizosavuta kupanga kukangana, ti imapangitsa kuti ndodo yoyamwayo iduke mosavuta, sucker rod centralizer imakhala yosinthika mwamphamvu, yokhudzidwa ndi chubu. khoma akhoza kuchepetsa kukangana kwa ndodo ndi chubu, ndipo akhoza kuonjezera kupanga moyo wa kupopera unit. The centralizer imalumikizidwa ndi sucker rod, m'mimba mwake wapakati wa centralizer ndi wamkulu kuposa kuphatikiza awiri akunja, kotero kuti imatha kupanga ntchito yapakati. Centralizer imapangidwa ndi zinthu zolimbana ndi mphamvu zambiri, ndipo imakhudzidwa ndi chubu kuti muchepetse abrasion kuti akwaniritse cholinga cha anti-abrasion.
