Centrifugal Gold Mining Dredging Machine Cutter Impeller Dredger Pump
Description of Centrifugal Gold Mining Dredging Machine Cutter Impeller Dredger Pump
The QSZ submersible slurry pump is a product developed by our factory's technical team, incorporating advanced foreign technology and tailored to the practical needs of most users. This coaxial motor-pump design allows the pump to operate directly within the medium, making it ideal for industries such as metallurgy, chemical processing, mining, and power plants. It efficiently handles slurries containing sand, ash, tailings, and other particulate materials, offering an excellent alternative to traditional slurry pumps. The pump features a mixing impeller at the bottom, which helps to mix settled particles with liquid, enabling high-concentration transport without the need for additional equipment. Its unique sealing system ensures balanced pressure inside and outside the oil chamber, significantly extending the mechanical seal’s lifespan. The motor is equipped with protection devices like water testing and overheating safeguards, ensuring safe and long-term operation in harsh environments. Applications of Centrifugal Gold Mining Dredging Machine Cutter Impeller Dredger Pump
- Pumping tailing slurry from industrial and mining sites
- Suction of silt from sedimentation basins
- Transporting silty sand or fine sand from seashores or ports
- Pumping powdered iron ore for international use
- Handling solid particles, coal slurry, sandstone, and other media
- Suction of fly ash and coal slime from power plants Main Features
1. Dry-type motor pump structure with mechanical seal protection against high-pressure water and contaminants.
2. Equipped with a mixing impeller that stirs residual material into a turbulent flow for efficient transport.
3. High wear-resistant materials used for impellers and wet parts, ensuring durability and resistance to clogging.
4. No limitation on suction head, allowing for thorough cleaning of sludge and debris.
5. Cost-effective without the need for auxiliary vacuum pumps.
6. No additional mixing or spraying devices required, simplifying operation.
7. Motor submerged, eliminating the need for complex ground structures and making management easier.
8. Mixing impeller directly contacts the deposit surface, allowing concentration control through depth adjustment.
9. Operates quietly and vibration-free when submerged, keeping the work area clean. Structure and Operating Principle
The QSZ submersible slurry pump operates by using a coaxial motor shaft to drive the impeller. As the impeller rotates, it transfers energy to the slurry, creating velocity and facilitating the movement of solids for effective slurry delivery. Construction Drawing
(1) Electrical Wiring
(a) The pump uses a four-core cable with three power lines and one ground wire. Protective devices are included, and the cable cores have specific functions indicated by labels. Ensure the ground wire is properly grounded and check resistance values with a multimeter.
(b) Insulation resistance should be tested during installation, and the motor’s insulation resistance must not be less than 5MΩ after being submerged.
(c) If the pump runs dry, it may be connected in reverse; swap any two of the three-phase power cables to correct the direction. (2) Installation Method
For mobile installations, the pump is vertically suspended into the water. Ensure the placement is smooth, 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 allowed
3. Maximum solid particle concentration: 30%, maximum medium density: 1.2kg/L
4. Maximum diving depth: 20 meters; minimum depth must submerge the motor
5. Operation mode: Continuous, with vertical orientation for optimal performance
Note: Customization is available if site conditions differ from these specifications. Application Medium
