The invention discloses a non-immersed seawater pump lifting device and method. The device comprises a ship body and a tower frame, wherein a liquid level sensor and a vertical seawater lifting pump are arranged at the bottom of one side of the interior of the tower frame, a water fetching and filtering assembly is arranged at the bottom of the other side of the interior of the tower frame, a pumpoutlet pipe is arranged at the input end of the vertical seawater lifting pump, and a self-priming device communicated with the pump outlet pipe is arranged on one side of the pump outlet pipe. According to the invention, position signals of a suction inlet of a seawater lift pump are fed back to a control box through a liquid level sensor to promote a tower frame to ascend or descend under transmission fit of a lifting assembly, a seawater lifting pump is kept at a certain position, the motor of the seawater lifting pump is higher than the water surface, and a pump outlet pipe with a filteris immersed in water to keep reasonable draught, so that the normal water supply work of the whole device is kept, the problem of part corrosion faults caused by frequent water immersion of a traditional seawater pump is solved, the stability of system operation is improved, and the maintenance cost of device work is reduced.
本发明公开了一种非浸没式海水泵提升装置及方法,包括船体和塔架,所述塔架内部一侧的底部分别设有液位传感器和立式海水提升泵,所述塔架内部另一侧的底部设有打水过滤组件,所述立式海水提升泵的输入端设有泵出口管,所述泵出口管的一侧设有相互连通的自吸装置。本发明利用液位传感器将海水提升泵吸入口的位置信号反馈到控制箱,促使塔架在升降组件的传动配合下上升或下降,将海水提升泵保持在一定位置,使其马达高于水面,同时带滤器的泵出口管浸没水中,保持合理吃水,以保持装置整体的正常供水工作,以解决传统海水泵频繁出现侵水导致部件腐蚀故障,增加提升系统运作的安定性,减少装置工作的维护成本。
