Detailed Guide on the Usage of Ocean-pump Submersible Sand Pump

I. Product Overview of Submersible Sand Pump

The submersible sand pump (also known as submersible sand suction pump, dredging pump, etc.) was designed by TAIAN Ocean Pump Co.,ltd in the 1990s for sand pumping in the Yellow River. After technological iterations, it is suitable for various working conditions. Its core structure includes a pump head, motor, oil chamber, and combined seal. The flow-through components are made of wear-resistant alloy (CR28) and undergo three heat treatment processes to ensure high wear resistance and passing capacity. It is widely used in metallurgy, mining, river dredging, and other scenarios, capable of transporting liquids containing solid particles such as sand, silt, and coal slag.

II. Usage Methods and Configuration Key Points in Different Working Conditions

(1) Sand Pumping/Sand Mining Scenarios

Core Requirements: Handle coarse sand, iron plate sand, etc., requiring anti-blocking and wear resistance.

1. Pump Type Selection:

• For coarse sand environments, select a large-particle submersible sand pump with thickened flow-through components made of high-chromium wear-resistant alloy.

2. Auxiliary Devices:

• Install a high-pressure water pump flushing device (flow rate 30% of the sand pump's flow, head >= 50m) to disperse sand layers; for iron plate sand, equip with electric/hydraulic reamer, and design special tooth shapes for enhanced stirring.

3. Electrical Protection:

• Support with a special control cabinet, providing protection against water ingress, overload, phase loss, and leakage to cope with motor impacts from fluctuating sand pumping concentrations.

4. Operation Tips:

• Monitor pressure and current data in real time, adjust the pump's depth and posture for optimal sand pumping efficiency.

(2) River Dredging Scenarios

Core Requirements: Handle media with garbage and silt, requiring anti-winding and efficient dredging.

1. Direct Dredging Mode:

• pump Configuration: Choose submersible sand slurry pump with a wide impeller flow channel, and install a filter screen at the pump bottom (mesh size customized based on flow diameter; double-layer screen for heavy debris).
• Reamer Design: Adopt plow-shaped tooth reamers combined with high-pressure water pumps to disperse silt layers; remove the stirring impeller to avoid debris entanglement.

2. Dredging Mode with Excavator Collaboration:

• Power Scheme: Drive the pump using the excavator's hydraulic system to solve power shortages in remote areas.
• Device Advantages: Stirring impeller at the pump bottom + side agitators/cages to loosen compacted sediments; unique sealing device reduces mechanical seal replacement frequency; hydraulic transmission enables stepless speed regulation and overload protection, preventing motor burnout.

(3) Slag Cleaning/Slurry Transportation Scenarios

Core Requirements: Handle smelting slag, tail sand, coal slag, etc., requiring high-temperature and corrosion resistance.

1. Basic Configuration:

• Install a stirring impeller under the pump (no extra stirring device needed for normal conditions). The medium temperature should <= 60 Celsius; for higher temperatures, add a cooling cover and inject circulating water.

2. Application Scenarios:

• Smelting plants: Transport smelting slag and tail sand slurry;
• Mines/coal preparation plants: Process tail sand, coal slurry, furnace slag;
• Sewage treatment plants: Discharge sludge and sand from sedimentation tanks, etc.

(4) Construction Mud Transportation Scenarios

Core Requirements: Long-distance mud transportation, requiring high efficiency, environmental protection, and low cost.

1.System Design:

• Configure high-head sand pumps in series to form a relay pumping station system, enabling transportation over dozens of kilometers.

2. auxiliary Devices:

• High-pressure water pump (head >= 50m, flow rate 80% of the mud pump's flow);
• Simple floating body to support the pump, adapting to water level changes;
• Frequency conversion system for intelligent operation, underwater work with no noise or vibration.

III. General Notes

• 1. Medium Limitations: Avoid transporting media containing flammable or explosive gases. If the temperature exceeds 60 Celsius, additional cooling is required.
• 2. installation Requirements: Select floating bodies, gantry cranes, etc., for hoisting based on working conditions to ensure appropriate submergence depth.
• 3. Maintenance: Regularly inspect wear of flow-through components and replace wear-resistant alloy parts; monitor the sealing device to prevent water leakage and motor damage.
