High Efficiency Submerged Electric Motor Submersible Slurry Pump
Description of High Efficiency Submerged Electric Motor Submersible Slurry Pump
The QSZ submersible slurry pump is a high-performance, technologically advanced solution developed by our factory's technical team. Combining foreign expertise with local user needs, this pump integrates the motor and pump in a coaxial design, directly submerged into the medium for operation. It is ideal for industries such as metallurgy, chemical processing, mining, and power plants, where conveying materials containing sand, ash, or tailings is required. The pump features an additional mixing impeller at the bottom, which helps to stir and transport high-concentration slurry without the need for auxiliary systems. Its unique sealing mechanism ensures balanced pressure, enhancing the reliability and longevity of the mechanical seal. The motor can be equipped with water testing, overheating, and other protective devices, ensuring safe operation even in harsh environments.
Applications of High Efficiency Submerged Electric Motor Submersible Slurry Pump
1. Pumping tailing slurry from industrial and mining operations.
2. Removing silt from sedimentation basins.
3. Transferring silty sand or fine sand from seashores or ports.
4. Transporting powdered iron ore from overseas locations.
5. Handling mud, coal slurry, sandstone, and other solid particles.
6. Suction of fly ash from power plants and coal slime.
Main Features
1. Dry-type motor pump structure with mechanical seal protection, preventing water and contaminants from entering the motor cavity.
2. Equipped with a main impeller and a mixing impeller for efficient stirring and transportation of settled solids.
3. Impellers and wet parts are made from high-wear-resistant materials, offering excellent wear resistance, corrosion resistance, and non-clogging performance.
4. No suction head limitations, allowing efficient removal of sludge and thorough cleaning.
5. Cost-effective without the need for auxiliary vacuum pumps.
6. No additional mixing or spraying devices required, making operation simple and convenient.
7. Motor submerged, eliminating the need for complex ground protection and fixtures, improving management efficiency.
8. Mixing impeller directly contacts the deposit surface, allowing easy concentration control through diving depth.
9. Operates silently and vibration-free when submerged, maintaining a clean working environment.
Structure and Operating Principle
The QSZ submersible slurry pump operates on a coaxial motor-pump design. When the motor rotates, it drives the impeller, transferring energy to the slurry medium, generating velocity, and enabling the flow of solids for efficient slurry delivery.
Construction Drawing
(1). Electrical Wiring:
- The pump uses a four-core cable: three power lines and one ground wire.
- Protective devices are included, with corresponding control cables.
- Each core has a specific function, as indicated on the identification card.
- Ensure correct connections during installation and test insulation resistance (minimum 5MΩ) after submerging the pump.
- If the pump runs dry, check the phase sequence and swap any two of the three-phase power cables if needed.
(2). Installation Method:
- The pump is installed vertically, suspended into the water.
- Ensure smooth placement, secure the cable, and connect the outlet pipe.
- This method is easy to install and move.
Operating Conditions
1. Power supply: 3-phase AC.
2. Maximum medium temperature: 40°C, no flammable gases present.
3. Maximum solid particle concentration: 30%, maximum medium density: 1.2 kg/L.
4. Maximum submersion depth: 20 meters, minimum submersion depth must cover the motor.
5. Operation should be vertical and continuous for optimal performance.
Note: Customization is available based on site conditions.
