Description
Technical field
The present invention relates to trailing suction hopper dredger dredge pump equipment technical fields, specially a kind of trailing suction hopper dredger underwater dredge pump system
System.
Background technique
The basic principle of trailing suction hopper dredger is that the drag head of lower end is transferred to bed surface by dredging tube, and rake teeth is pressed into mud by being self-possessed
Soil passes through the shear action of rake teeth, high-pressure flush and the water flow for flowing to suction inlet during hull navigates by water forward towing
Erosion effect, mud mixture are sucked and are transported to by dredge pump in the spoil hopper of dredger, and remaining water is overflow by adjustable after sedimentation
Streaming system is discharged into the water body of outboard, once being loaded with desilting material in spoil hopper, dredger just drives to specified throwing mud
Area or the unloading of hydraulic reclamation area.
For digging deep dredger greatly, use submersible pump that can provide very big freedom degree for the linear design of hull, simultaneously
The vacuum degree of dredging concentration and dredge pump entrance can be improved using submersible pump, therefore dredger can assemble the suction of smaller diameter
Pipe, to mitigate quality and save the cost, but since underwater pump installation overall dimensions are bigger in shallow cut depth situation, very
It is easy that device is made to touch mud, to damage underwater pump installation, furthermore in the case where an ultra shallow digs depth, rake suction pipe can not be completely filled with
Water cannot form vacuum, and then cause rake suction pipe that can not inhale mud.
