The 12-inch pump box is integrated, and the pump head is directly connected with the gear box, that is, the bracket of the dredging pump is integrated with the gear reduction box, which greatly reduces the weight of the entire pump and the gear box unit, and reduces the volume of the unit, especially It shortens the axial dimension of the unit, which in turn shortens the size of the ship. The Guizhou dredging pump makes the dredger more reasonable. It is worth mentioning that the 300wn dredging pump on the 350m3/h (whole) bucket wheel dredger adopts the gearbox structure of the input and output shaft horizontal transmission, and the 300DOD sedimentation tank mud pump, which reduces the center height of the unit. Under the condition of certain depth of digging and suction pipeline, the drip pump can increase the suction concentration of the dredging pump system by 30%.
