The invention discloses a miniature plunger pump for a long-distance underwater glider. The miniature plunger pump comprises a pump shell, a first sealing ring, a deep groove ball bearing, an inclined shaft, a return spring, a thrust bearing, a plunger, steel balls, a baffle ring, an oil cylinder, a positioning pin, a second sealing ring, an outlet valve plate, an outlet valve cover, a rear cover, a first steel ball and a second steel ball. The thrust bearing is located between the plunger and the inclined shaft, the return spring is located on the rear end face of the plunger and connected with the plunger, the first steel ball and the second steel ball are located in the oil cylinder, the rear end of the plunger is located in the oil cylinder, through the design of the return spring, the thrust bearing and the inclined shaft, the size of the plunger pump is reduced, the plunger and the return spring are driven to move through the thrust bearing, and therefore the steel balls in the oil cylinder are driven to move, and sufficient pressure is provided for an external leather bag by using liquid oil.

    本发明公开了一种长距离水下滑翔机用微型柱塞泵,包括泵壳、第一密封圈、深沟球轴承、斜轴、回程弹簧、推力轴承、柱塞、钢球、挡环、油缸、定位销、第二密封圈、出口阀片、出口阀盖、后盖、第一钢球、第二钢球,推力轴承位于柱塞与斜轴之间,回程弹簧位于柱塞的后端面,与柱塞弹性连接,第一钢球与第二钢球位于油缸内,柱塞的后端位于油缸内,通过回程弹簧和推力轴承与斜轴的设计,减少了柱塞泵的体积,通过推力轴承带动柱塞及回程弹簧运动,从而带动油缸中的钢球运动,用液油为外部皮囊提供了充足的压力。
