▪ How does a submersible power-plant pump work?
It usually works based on the centrifugal principle. The motor drives the impeller to rotate, and the blades force the ash - containing slurry to rotate. Under the action of centrifugal force, the slurry flies out of the impeller, forming a low - pressure area at the center of the impeller. Then, the slurry is sucked into the impeller through the suction pipe, and is discharged through the outlet after being pressurized, realizing the transportation of the ash - containing slurry.
▪ How to maintain the submersible power-plant pump?
Regularly check the insulation value of the motor to water, and ensure that the motor is absolutely insulated from water when running underwater. Check the wear of vulnerable parts, such as impellers and casings, and replace them in time if they are worn. In addition, avoid the pump running dry, and deal with problems in time when the pump is abnormal.
▪ Are submersible power-plant pumps safe?
They are relatively safe. The motor of the submersible pump is hermetically sealed, and the cables are usually well - insulated and sealed. As long as the correct pump model is selected according to the well diameter and installation requirements, and the installation and operation are carried out in strict accordance with the specifications, the risk of electric leakage and other safety accidents is low.
▪ How to choose the right submersible power-plant pump?
First, analyze the actual needs, such as the flow and head required for ash removal in the power plant, and select a pump with a suitable flow and head according to the design requirements of the power - plant system. Second, consider the nature of the medium, such as the particle size and concentration of ash - containing slurry, and choose a pump with a suitable impeller and casing material. In addition, the power of the pump should be matched with the power supply capacity of the power plant to ensure normal operation.
▪ Bottom Ash and Fly Ash Removal
In coal - fired power plants, submersible pumps are crucial for dealing with bottom ash and fly ash slurries. They can transport the ash from the bottom of the boiler or the ash-collecting equipment to the designated disposal area or the subsequent treatment system, ensuring the normal operation of the power-generation equipment.
▪ Sump Cleaning
Ash, coal chunks, and other debris in the sumps of power plants need to be pumped out regularly. Submersible pumps can be directly submerged in the sump for operation, effectively preventing clogging and wear, and can efficiently clean up the ash and debris in the sump.
▪ Ore Slurry and Waste Rock Slurry Handling
For mines with a large amount of waste materials, submersible pumps can pump out the slurry of crushed ores and waste rock, and transport the slurry to different stages of separation and purification in the beneficiation process.
▪ River and Lake Dredging
In river and lake dredging projects, submersible pumps can be used to remove sediment containing ash-like substances at the bottom of rivers and lakes, which is helpful for improving the water environment and flood - control capacity.
▪ Coarse Ash Mining
In mines, submersible pumps can extract coarse ash slurry from ponds or basins and transport it to processing facilities. They can also be used for tailings management, dewatering, and pipeline transport of coarse ash slurry, helping to improve the efficiency of the mining production process.
▪ Oxide Scale Precipitation Cleaning
In the hot - rolling process of steel plants, there are a large number of oxide scale precipitates in the swirl sedimentation tank of the turbid water circulation system. Submersible pumps can be used to clean up these precipitates to ensure the normal operation of the circulation system.
