Kind Code:
A1
Abstract:
A thrust block (100), a motor, and an underwater booster. A first through hole (110) is provided at the center of the thrust block (100) along the axial direction, and water grooves (120) are provided on one end surface, one end of the water grooves (120) extending to a side wall of the thrust block (100). By means of the effect of the water grooves (120), the thrust block (100) forms a water membrane when rotating, thus reducing abrasion and extending the service life.
