6 8 10 12 inch Submersible mixing dredger

6～12inch Submersible mixing dredger is developed on the basis of our electric pump. Is powered by the hydraulic system, hydraulic motor for the executive components, the hydraulic energy into the mechanical energy of the new hydraulic slag slurry pump. The bottom of the pump and the traditional submersible slurry pump are roughly the same, the flow parts are made of high wear resistant alloy casting. At the same time, the main impeller of the pump and the flow channel increase, so that the medium through stronger, solid liquid extraction concentration is higher than the electric pump.

The hydraulic motor adopts domestic high speed hydraulic motor, which has the characteristics of compact structure, reasonable, good performance, high efficiency and stable operation.

Manufacturer credibility guarantee: one year warranty, wooden packing; Can be customized various special materials, and can be customized according to the actual working conditions.

Function Description:
Sand mining, silt removal, slag removal, slurry transportation, river dredging, wharf silt removal, flood drain silt removal.
When the river is dredging sand, a small submersible pump can be hoisted into the water to pump sand. Can also be mine vertical pump to sit on the ship, the bottom of the water hose with the bottom valve filter, the bottom valve filter into the water pumping sand.
Reservoir or hydropower station underwater equipment is buried by silt, can not operate monitoring is, are used to lift sand drainage submersible pump into the water to discharge silt. In view of the problem of the diving depth of the equipment for sand mining, the submersible pump for sand drainage can solve the problem of sand mining and mining at the depth of 0 ~ 40 meters. In the process of sand mining, the average concentration of sand mining may be low or high.

After using the hydraulic agitator developed by our company, the problem of slurry concentration is solved perfectly. The application of hydraulic agitator in other river channels and sea sand mining conditions has proved that the effect is very good. When the river is dredged and silted, the general mud is thin, and the small sand-discharging submersible pump is directly lifted into the water to pump the sediment slurry. In addition to the problem of submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump submersible pump. The solid sediment will be stirred up to form a relatively uniform sediment slurry, this process is called slurry. And in the pumping sand dredging will encounter the problem of slurry. Large sand pump with large flow rate, small sand pump with stirring wheel, external mechanical stirring equipment, auxiliary hydraulic agitator and other technological means are used to solve the slurry making problems. In fact, in the condition of deep water sand pumping, the submersible pump is added with a pneumatic balance device, and the pressure difference between inside and outside the motor cavity is balanced by adding compressed air into the motor cavity. After adopting this measure, the dredging submersible pump can work under 30 meters of water successfully, and the actual working effect is quite ideal. The parameters only show one scheme, please contact us for specific requirements, so that we can provide accurate scheme according to your needs

For deep water wharf construction wharf peripheral seabed sediment can be excavated by large dredging vessels, clear out the channel, but around the wharf, dredging sand is difficult to take care of the local sediment is difficult to deal with. The water depth is 10 ~ 20 meters, which is difficult to be sucked up by the ship's slag slurry pump. Selection of sand drainage submersible pump, with auxiliary equipment can dive to a very deep seabed, and then equipped with a hydraulic agitator, can solve this problem.
