HCC - Model 160/30-GR - Hydraulic Dredger
From Dredger HCC 160/30
Productivity оf the pulp: 150-200 m3/h. Productivity оf the soil (hydraulic deposition of soil category 1-2): 20-40 m3/hour; from180 m3 for the shift(8 hours). Dimensions in working position: maximum length 12 m, maximum width 4.4 m, maximum height 2.8 m, board height 1 m, draft 0.55 m. Weight: 6.5 t. The hydraulic dredger is equipped with an arrow. Suction pipe length is 6 m with hydraulic washing-out (jet), with pump capacity 11 kW, the water supply is 70 m3 per hour with hydraulic drop of 85 m.
Power unit: D-264 (capacity of 170 kW, 1800 rev /min, fuel consumption - 12 l/h) or equivalent.
Fuel tanks capacity 550 l.
The generator's own needs 25 kW.
Pump: 7'/6'-350-NS (made by VVV-SPETSTEKHNIKA). Pump specifications: 7 inch/6 inch, soil outlet from15% per hour, hydraulic drop of water column– 40 m, maximum capacity – 55 kWt, rotation frequency – 1500 rev./min. Hydraulic drive.
Technical characteristics of the pump (are provided geodetic lift is not more than 10 m for soil 1-2 category):
- output up to 25% at the distance of transportation of pulp to 150 m (capacity 30 m3 of soil)
- output up to 20% at the distance of transportation of pulp to 200 m (capacity 25 m3 of soil)
- output up to 15% at the distance of transportation of pulp to 300 m (capacity 20 m3 of soil)
- output up to 10% at the distance of transportation of pulp to 500 m (capacity 15 m3 of soil)
Dredge this modification lifts the soil with water depth 0.5 - 5 m, pushing through slurry pipeline 500 m geodesic a slope of not more than 10 m.
Control Room is equipped with:
- gauges (gauge, ammeter, frequency meter, pressure gauge (on the soil pump discharge nozzle, on the nozzle to wash the seal on the pipe hydrowashout));
- remote control of dredger movement;
- emergency shutdown system for dredger's network;
- observation devices for main engine.
For lighting on the dredger used two-wire isolated power distribution system voltage of 220V, 50 Hz.
For mains used a three-phase isolated power distribution system 380V, 50Hz.
For networks of control and signaling, as well as emergency lighting used two-wire isolated power distribution system voltage 24V DC.
Energy supply: self-contained.
The movement of hydraulic dredger is performed with the help of 4 winches with the capacity of 2.2 kW. Ladder winch - 2.2 kW, tracing force 3.5 t.
Pipeline diameter 125 mm
The enterprise guarantees the operation of the equipment for 1 year or 1800 Moto hours.
Maximum term of manufacturing is 2.5 months.
- Performance on the ground: 10-50 m3/h
- Power supply: self-contained
- Depth development: up to 7m
- Methods of suction: hydraulic washing-out
