About 18 Inch Inboard Pump Cutter Suction Dredger Dredge Pump
The dredge pump is high efficiency made from wear resistant casting impeller and liners fitted on heavy duty shaft and high quality roller bearings.
The impeller is fitted on the shaft by trapezoid thread directly machine on the shaft end. The shaft sealing is a water cooled sealing that can be replaced after wear life. The impeller is a special type of double curved vanes high efficiency and wear life optimized tested in laboratory and onboard of dredgers. The impeller is fixed on the shaft
by trapezoid thread machined directly in the impeller hub.
The pump casing has a shape of a volute designed of a high efficiency and wear life optimized tested in laboratory and onboard of dredgers. The pump liners are made of high wear resistant materials and thick wall thickness to maximize the wear life. The casting covers are made from fabricated steel stiffened where necessary and
machining to fit the case and the liners.
About 18 Inch Inboard Pump Cutter Suction Dredger Hydraulic system
The hydraulic system is the most important part of the river sand dredger and bucket wheel dredger. The hydraulic system is very demanding and strict; it is the main artery of the entire sand dredger. The side traction winch of the dredger, the lifting winch and the cutting head are driven by hydraulic motors.
We use hydraulic pressure to drive the entire dredger, including winches, cutting machines, hydraulic cylinders, etc. The valve is REXROTH, and the hydraulic control system is SIEMENS PLC.
2. About Leader Dredger Inboard Pump Cutter Suction Dredger:
1. The dredging pump is driven by the main diesel engine through a
reduction gear box
2. The alternator, driven by an auxiliary diesel engine, provides
power and lighting for the entire dredger. The generator set
supplies power for lighting and emergency situations when not
working
3. The hydraulic oil pump is driven by an auxiliary diesel engine
4. Variable speed winches, winches and hoisting winches are driven
by hydraulic motors
5. The cutting head is driven by a hydraulic motor; the bearing of
the cutting machine has a lubricating and sealing device
6. The dredger is moved by rotating the pendulum alternately and lifted by hydraulic cylinders
