Productivity оf the pulp: 800-1000 m3/h.
Productivity оf the soil (hydraulic deposition of soil category 1-2): 80-200 m3/hour; from 1000 m3 for the shift(8 hours).
Dimensions in working position: maximum length 21 m, maximum width 3 m, maximum height 3.8 m, board height 1.5 m, draft 0.75 m . Weight: 20 t.
The hydraulic dredger is equipped with an arrow. Suction pipe length is 10 m with hydraulic washing-out (jet), with pump capacity 25 kW, the water supply is 90 m3 per hour with hydraulic drop of 90 m.
Power unit: YAMZ-238 D1 (capacity of 275 kW, 1800 rev /min, fuel consumption - 25 l/h) or equivalent.
Fuel tanks capacity 1700 l.
The generator's own needs 40 kW.
Pump: 10'/8'-740-PET (made by VVV-SPETSTEKHNIKA). Pump specifications: 10 inch/8 inch, soil outlet from15% per hour, hydraulic drop of water column– 40 m, maximum capacity – 170 kWt, rotation frequency – 750 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 250 m (capacity 200 m3 of soil)
2. output up to 20% at the distance of transportation of pulp to 450 m (capacity 160 m3 of soil)
3. output up to 15% at the distance of transportation of pulp to 550 m (capacity 100 m3 of soil)
4. output up to 10% at the distance of transportation of pulp to 650 m (capacity 80 m3 of soil)
Dredger this modification lifts the soil with water depth 1 - 7 m, pushing through slurry pipeline 650 m geodesic a slope of not more than 20 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 3 kW. Ladder winch - 5 kW, tracing force 7.5 t.
Pipeline diameter 250-315 mm
The enterprise guarantees the operation of the equipment for 1 year or 1800 Moto hours.
Maximum term of manufacturing is 4 months.
For the selection of pipeline, please fill in the questionnaire because diameter slurry pipeline depends on the length of pulp conveying distance.
