ERT (Ndetse n'ubunini bwa Rubber):
Nibyiza guhindura imiterere yimyubakire ya stator, stator elastomer layer ya Uniform Thickness downhole moteri iroroshye kandi niyo. Ibiranga moteri yamanuka ni uburebure bugufi, imbaraga nyinshi, umuvuduko ukabije, umuvuduko muke, kuzunguruka cyane, ndetse no kwaguka kwinshi, gukoreshwa cyane, imiterere myiza hamwe na misa yoroheje. By'umwihariko, ibiranga bishobora kongera ubuzima bwa moteri yo hasi kandi bikanoza imikorere yo gucukura mu iriba ryimbitse cyane, iriba ryerekezo hamwe nubushyuhe bwo hejuru.
Kurwanya Ubushyuhe bwo hejuru hamwe namavuta ashingiye ku byondo:
Moteri yamanuka ikwiranye nubushyuhe bwo hejuru, sisitemu yo hejuru ya peteroli. Mubihe biri munsi ya 180 ° C hamwe namavuta maremare, stator yakozwe na stator elastomer ifite igipimo kinini cyo kugumana imbaraga zikomeye, imbaraga zamarira nibindi bintu. Elastomer irwanya amavuta hamwe nubunini bufatika bwo kwivanga ifite neza gukoresha ingaruka mubushyuhe bwo hejuru, ibyondo bya peteroli.
Kurwanya ruswa:
Nyuma yo gutera ruswa kugirango ikore igifuniko kidasanzwe, rotor nibyiza kwangirika, isuri kandi irwanya abrasion. Kandi moteri yamanuka irakwiriye igihe kinini mumazi yangirika.
Gucukura ikirere:
Gucukura ikirere birashobora kurinda ikigega neza, kunoza umuvuduko wo kwinjira, kugabanya cyane igihe cyo gucukura, gufata ingamba zo kwirinda ibyondo no kugwa kwa borehole, ubu birakoreshwa buhoro buhoro. Moteri yo kumanura ikirere itwarwa na gaze, ifuro nandi mazi yoroha, itanga imbaraga kumanuka kandi ikagenda bito kugirango yinjire mu rutare. Moteri yo gucukura ikirere ifite moteri isabwa muburyo bwa tekiniki yuburyo bw'iteraniro, igishushanyo mbonera cya stator ya moteri n'ibisobanuro byerekana.
