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 hydraulic washing-out (jet), with pump capacity 350 kW, the water supply is 400 m3 per hour with hydraulic drop of 120 m
Power unit main: CAT (capacity of 1400 kW, 1900 rev /min, fuel consumption - 120 l/h).
Power unit: CAT (capacity of 450 kW, 1800 rev /min, fuel consumption - 45 l/h)
Fuel tanks capacity 15500 l.
The generator's own needs 300 kW.
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 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 10 kW. Ladder winch - 15 kW, tracing force 7.5 t.
Pipeline diameter 700-850 mm
The enterprise guarantees the operation of the equipment for 1 year or 1800 Moto hours.
Maximum term of manufacturing is 10 months.
Power of main engine may vary, depending on the distance of transportation of the pulp and requirements for operation.
