Abstract

The invention discloses a deep sea mineral conveying diaphragm pump control system based on stroke switching, which comprises a diaphragm pump and a switch valve module, the diaphragm pump comprises a pump body and a diaphragm, and the pump body is divided into a left side space and a right side space through the diaphragm clamped and fixed on the pump body; the switch valve module comprises a rack, a diaphragm moving mechanism, four pressing type one-way valves, a set of driving mechanism and two sets of triggering mechanisms, and pressing rods of the pressing type one-way valves make contact with the cams through rolling wheels rotationally installed below the pressing rods. Through contact between the roller and the cam, face-to-face contact is achieved, abrasion of the cam and the pressing rod is avoided, and the stability and durability of long-term work of the cam are improved. The triggering time of the control system of the deep sea mineral conveying diaphragm pump is controlled at the stroke final position of the diaphragm, so that the diaphragm pump can be controlled without other power equipment, and the state change time of each valve is accurate.

Description

technical field [0001] The invention relates to the field of marine mining, in particular to a control system for a diaphragm pump for conveying deep sea minerals based on stroke switching. Background technique [0002] Deep-sea mining needs to vertically transport the minerals collected by thousands of meters deep seabed mining vehicles to the sea surface mining ships. The current vertical transportation schemes are basically hydraulic pipeline lifting. The hydraulic pipeline lifting deep sea mining system is mainly composed of a seabed mining vehicle, a pipeline transportation system and a surface mining ship (the basic structure is as follows: figure 1 shown). Among them, the pipeline transportation system includes hose pumps for mining vehicles, hoses, intermediate warehouses (including feeders), hard pipes and submersible centrifugal pumps. Centrifugal pumps generally use multi-stage space guide vane centrifugal pumps, and individual systems also consider diaphragm pu...
