An air lubrication system utilizing a vacuum pump to convey air is characterized in that the vacuum pump is provided with a working water inlet and an air suction port, a vacuum pump working water power source is connected with the vacuum pump working water inlet through a water inlet pipeline to convey working water into the vacuum pump, and the water inlet pipeline is provided with a working water inlet stop valve; the vacuum pump air inlet device is connected with a vacuum pump air suction port through an air inlet pipeline, and a vacuum pump air suction check valve is arranged on the air inlet pipeline to feed air into the vacuum pump. The vacuum pump is connected with a discharge pipeline, a vacuum pump outlet check valve is arranged on the discharge pipeline, a vacuum pump discharge port is formed in the end portion of the discharge pipeline, and the vacuum pump discharge port faces the stern at the bottom of the ship body to discharge water and gas mixtures. In order to solve the problem of high initial investment of a ship owner, the ship raw water fire extinguishing system is used as a power source of working water of the vacuum pump, main functional equipment is the vacuum pump, and the vacuum pump is low in cost and can provide tiny thrust for advancing of the ship.

    一种利用真空泵输送空气的空气润滑系统,真空泵带有工作水进口和吸气口,真空泵工作水动力源通过进水管路与真空泵工作水入口连接,将工作水送入真空泵中,进水管路上设置有工作水进口截止阀;真空泵进气装置通过进气管路与真空泵吸气口连接,进气管路上设置有真空泵吸气止回阀,将空气送入真空泵中;真空泵与排出管路连接,排出管路上设置有真空泵出口止回阀,排出管路端部带有真空泵排出口,真空泵排出口在船体底部朝船艉,将水、气混合物排出。本发明为了降低船东初始投资高的问题,利用船舶原水灭火系统作为真空泵工作水的动力源,主要功能设备为真空泵,该真空泵成本较低,可以对船舶前进提供微小的推力。
