The invention discloses a magnetically-driven water-jet propulsion pump, comprising a pump shell. A stator is arranged between the top and the bottom of the inner surface of the pump shell; a ball bearing is arranged on one side of the inner surface of the pump shell; a rotor is arranged on one side of the ball bearing; an output rod is arranged at one end of the rotor; an impeller is arranged at one end of the output rod; a sealing bearing is arranged between one side of the output rod and one side of the pump shell; flow inlet holes are formed in the top and the bottom of the other side of the pump shell; and a flow speed monitoring device is arranged at the position, located on one side of the flow inlet holes, of the top of the inner surface of the pump shell. According to the magnetically-driven water-jet propulsion pump, the problems that when an existing water-jet propulsion pump is used, the water inflow effect is likely to be affected when a rotating shaft rotates, meanwhile, the inflow speed cannot be monitored to a certain degree, then the pump body cannot be decelerated and stopped in time when the pump body is damaged, and the use effect of the propulsion pump is reduced.

    本发明公开的一种磁驱动式喷水推进泵,包括泵壳,所述泵壳的内表面顶部与底部之间设置有定子,所述泵壳的内表面一侧设置有滚珠轴承,所述滚珠轴承的一侧设置有转子,所述转子的一端设置有输出杆,所述输出杆的一端设置有叶轮,所述输出杆的一侧与泵壳的一侧之间设置有密封轴承,所述泵壳的另一侧顶部与底部均开设有进流孔,所述泵壳的内表面顶部且位于进流孔的一侧设置有流速监测装置。本发明所述的一种磁驱动式喷水推进泵,解决了现有的喷水推进泵在进行使用时,其转轴在进行转动时,容易影响水进流的效果,同时不能对于进流速度进行一定的监测,其次不能再泵体损坏时及时将其进行减速停止,降低了推进泵的使用效果等问题。
