VVV-Spetstekhnika - Model HCC 250/40-GR-E -Dredger

Productivity  the pulp: 250-320 m3/h.

Productivity  the soil (hydraulic deposition of soil category 1-2): 30-55 m3/hour;   from240 m3 for the shift(8 hours).

Power unit: electrical, power  85 kW, 1500 rev /min, 380 W) or equivalent.

Pump:  8`/6`-400-NS (made by VVV-SPETSTEKHNIKA). Pump specifications: 8 inch/6 inch, soil outlet from15% per hour, hydraulic drop of water column– 40 m, maximum capacity – 65 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):

1. output up to 25% at the distance of transportation of pulp to 150 m (capacity 30 m3 of soil)
2. output up to 20% at the distance of transportation of pulp to 200 m (capacity 25 m3 of soil)
3. output up to 15% at the distance of transportation of pulp to 300 m (capacity 20 m3 of soil)
4. 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 - 15 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: coastal
• Depth development: up to 7m
• Methods of suction: hydraulic washing-out
