Jet boat: it uses vacuum principle to absorb sand, which is suitable for the working environment where the sand is loose and the sand pumping depth is more than 15m; it is not suitable when there is a mud layer, so it needs tools to open the mud layer. It can be pumped down 50m, and can be used when the diameter of sand is relatively large.
Lifting pump boat: it is suitable for the working environment where the sand is loose and the sand pumping depth is more than 15m; it is not suitable when there is a mud layer, so tools are needed to open the mud layer. The depth of pumping can reach 100m by using self gravity sinking. Generally speaking, the outlet of the pump crane ship is equipped with thick pipes.
