It is recommended to use vertical sand pump with floating tank / submersible sand pump in the sand selection of the construction work that is not fixed or moves frequently. It is more practical and simple to operate. Before use, the construction progress should be designed according to the thickness of the sandy layer on the site, and the parameters such as stone particle size, sandy ratio, and suction depth should be compared for reference.
It is more convenient to use a support frame to be fixed on a ship or mobile vehicle. When submerged and lowered to the level of sediment level, observe the sand outlet depth of the tube head to determine the slurry concentration ratio, reasonably arrange the suction speed and sand extraction depth to adjust the sediment output Plan and matching. If conditions permit, it can be more efficient to add more aspirating probes. At the same time, as the output of sand continues to increase, the sand selection machinery must also be formed in a scientific manner to better ensure the rate of fine sand production.
