Productivity оf the pulp: 6000-7000 m3/h.
Productivity оf the soil (hydraulic deposition of soil category 1-2): 600-1200 m3/hour; from 7000 m3 for the shift(8 hours).
Dimensions in working position: maximum length 45 m, maximum width 6.5 m, maximum height 5.5 m, board height 2.8 m, draft 1.1 m . Weight: 95 t.
The hydraulic dredger is equipped with an arrow. Suction pipe length is 20 m with cutter ripper, power 250 kW, frequency 20 rev/min, hydraulic drive.
Power unit main electrical: capacity of 1600 kW, 500 rev /min, 6000 V.
Pump: 20'/18'-830-PET (made by VVV-SPETSTEKHNIKA). Pump specifications: 20 inch/18 inch, soil outlet from15% per hour, hydraulic drop of water column– 70 m, maximum capacity – 1100 kW, rotation frequency – 500 rev./min. Hydraulic drive.
Technical characteristics of the pump (are provided geodetic lift is not more than 30 m for soil 1-2 category):
1. output up to 25% at the distance of transportation of pulp to 1000 m (capacity 1200 m3 of soil)
2. output up to 20% at the distance of transportation of pulp to 1500 m (capacity 1000 m3 of soil)
3. output up to 15% at the distance of transportation of pulp to 2000 m (capacity 800 m3 of soil)
4. output up to 10% at the distance of transportation of pulp to 3000 m (capacity 600 m3 of soil)
Dredger this modification lifts the soil with water depth 1 - 18 m, pushing through slurry pipeline 3000 m geodesic a slope of not more than 30 m.
Control Room is equipped with:
For mains - used three-phase isolated power distribution system voltage of 6000 V, 50 Hz.
For network used three-phase isolated power distribution system voltage of 380 V, 50 Hz.
For lighting network dredger used two-wire insulated system power distribution 220V 50Hz.
To control and signaling networks, as well as emergency lighting used two-wire insulated electrical distribution system 24V
Energy supply: coastal.
The movement of hydraulic dredger is performed with the help of 4 winches with the capacity of 10 kW. Ladder winch - 15 kW, tracing force 7.5 t.
