On the one hand, the addition of submersible pumps increases the depth of digging and increases the concentration. Submersible pumps are widely used in large-scale projects. At the same time, the use of high wear-resistant materials for the inner shell can greatly extend its service life, reduce the operating cost of the dredger, and improve the safety performance of the cutter dredger. With the protection of the outer shell, the inner shell can be fully utilized. The shell of the double-shell pump is not in contact with the mud and is not subject to wear, so the double-shell pump is much safer than the single-shell pump. Power consumption generally accounts for 60% to 70% of the energy supply of the whole ship, and its working characteristic parameters roughly represent the performance of the dredger 1. Judging from the current mainstream design, hydraulic transmission is the main transmission method adopted by the dredger dredging equipment.ĭredging pump is one of the main working parts of river dredger for sale. These advantages just meet the working requirements of the working mechanism of cutter suction dredger. The working medium of the hydraulic system has a certain elastic shock absorption capacity, which can make the hydraulic transmission system operate stably and reliably. The advantages of the hydraulic system include: light weight per unit of power, small inertia, fast response speed, and easy start and stop. In addition, the trolley and the running anchor are also driven by the hydraulic system. The main hydraulic components are: driving the reamer, driving the bridge up and down, controlling the ship to swing left and right through the traverse winch, and controlling the positioning pile up and down through the positioning pile cylinder. The hydraulic system is a systematic project, with strong professionalism and comprehensiveness. Leader Dredger's hydraulic system is distributed throughout the dredger and is the core control system of the entire ship.
