Description

CHARACTERISTICS: Dredgers With submersible pumping unit DESCRIPTION : The dredger with an electric submersible dredge pump produced by Toyo with the capacity by pulp reaching 720 m3/h, while the output by soil is not less than 200 m3/h, at the head of up to 22 m.w.c. ADST-600Е is designed for: Excavation of 1-3 categories’ soils; Recovery of sand and other non-ferrous materials; Aggradation of dikes, roads, construction sites; Dredging operations. The pump head ensures the handling of sand and gravel mixtures at the distance up to 350 meters horizontally. The dredging depth reaches 30 meters. The dredger has been designed with the implementation of a completely new concept of soil intake due to the application of a submersible pump. It was specially designed for operation with highly viscous mixtures having the high content of solid particles. The dredger should not be equipped with soil withdrawal frame and the system of soil suction (in particular, suction pipeline and ripping device). The suggested design foresees the installation of an electric submersible pump with a built-in motor, as well as a mechanic agitator. The latter ensures an uninterrupted load of the concentrated mixture to the suction pipe. In such a way, the pumping of pulp with the 60%-concentration of solid inclusions is ensured. The pump is equipped with a low-speed electric motor with high starting torque. The motor power is 110 kW. A service factor of the motor is 1.35. Hence, the pump can work at significant overloads. The speed of the pump shaft rotation is 590 rpm ensuring the pump flow parts’ wear resistance. The provisional lifetime of flow part details is no less than 2000 hours.
