Abstract

يتعلق الاختراع الحالي بآلية موازنة دفع محوري axial thrust balancing mechanism لجهاز عمود تدوير rotating shaft apparatus (102) مثل مضخة دوارة rotary pump توفر تعويض دفع ذاتي التنظيم مع تجنب التلامس والتآكل بين العناصر الدوارة (400) والثابتة (402). ويشتمل عضو دوار (400) مثبت بالعمود (102) على جزء ذكر أسطواني cylindrical male section قريب من جزء أنثى اسطواني cylindrical female section لعضو ثابت (402) غير دوار لكن لا يمتد داخله، حيث تختلف فجوة gap (500) متكوِّنة بينهما في العرض عن طريق إزاحات عمود الدفع المحوري . ويسلّط المائع المضغوط pressurized fluid داخل جزء أنثى female section قوة تعويض دفع على العضو الدوار الذي يتحكم فيه حجم الفجوةgap size. ويكون قطر الجزء الأنثى female section أكبر من قطر الجزء الذكر، مما يمنع أي تلامس بينهما. ويمكن دمج الآلية التي يتم الكشف عنها مع اسطوانة تعويض دفع thrust-compensating drum (200) لتقليل الدفع إلى مستوى متبقٍ يمكن تنظيمه. ويمكن أن يختلف العضو الدوار (400) والعضو الثابت (402) تدريجيًا لتوفير مجموعة من الفجوات gaps (110) والغرف الوسيطة intermediate c
