PTCSD-650

1. Cutter suction dredger brife :PTCSD-650 cutter suction dredger is widely used for river lake port and inside waterways etc . cutter suction dredger can process sand mud gravel from all kinds of dredging project . Set sail cutter suction dredger adopts good quality device to achieve the highest performance .let the customer spends the lowest cost to Get the highest profit Configuration of Cumins diesel engine ( Otherwise can provide carter Weichai and others  diesel engine brand )Shijiazhuang slurry pump and hydraulic pump from the America or Germany . all configurations can reach the low failure low fuel consumption high capacity and high efficiency.
2. Basic parameter :

   Total length:  48m（contains spud carrier）

   (The total length from head of cutter to the spud)

   Total width:  9.3m

   (The left balance hull is 2.75m wide, the middle engine room is 3.8m wide, and the right balance hull is 2.75m wide）

   Total height:  7.3m

   (The distance from the bottom plate to the deck is 2.5m, the height of the rest room is 2.4m, and the height of the central control room is 2.4m.)

   Length of floating body on both sides: 40m  

   (The front half of the hull is 20m long, the back half of the hull is 20m long)

   Length of floating body in the middle: 19m                  

   Full loaded displacement: 370.6T

   Load draft: 1.3m

   Designed draft: 1.0m     

   Frame spacing: 600mm

   Standard dredging depth: 15.0m

   (When the angle between the reamer bridge and the water surface is 45°, the vertical height from the water surface to head of the reamer is 15m.)

   Minimum dredging depth: 2.5m

   If the underwater position of the reamer is higher than 2.5m, air may be sucked, which will lead to the performance degradation of the main pump. The service life of the main pump will be reduced due to cavitation caused by the suction of air.)

   Conveying distance: 3000m

   Minimum conveying distance: 800m (A narrowed mouth is required.)

   Mixed workload:  5500m³/h

   (When the volume concentration of the silt is 10%, the mixed workload is about 550m³/h. When the volume concentration of the sandstone is about 20%, the mixed workload is about 1100m³/h.)

   Suction / discharge pipe diameter：700mm (inner diameter)/650mm (inner diameter)

   Total installed power: 2356 kw

   Total weight：300T

   4.Performance of dredger:

   1. When the horizontal conveying distance of this model of dredger is 3000m, the total flow of the water head is 5000m³ per hour. When the angle between the bridge and the water surface is 45 °, the digging depth is up to 15m. HDPE pipe is used as the conveying pipe. The length of a single pipe is 11.5m. For a single polyethylene pipe 11.5m long, 3 sets of buoy are installed, so as to ensure that the pipeline floats normally on the water surface. The pipes are connected with a rubber pipe with a length of 1.8m, so as to ensure the flexible state of the pipe on the water surface.

   2. Inner diameter of the conveying pipe: 650mm

   Dredging depth: 15m

   Maximum volume concentration: 30%
