Malfunction and Solution of Mining Submersible Pump
Mining submersible pumps are mainly used for drainage in the central pump room of coal mines. Centrifugal water pumps are commonly used for emergency drainage or re mining drainage after coal mine flood disasters.
feature
1. The motor and pump body can be submerged in water, ensuring safe and reliable operation.
2. Mining submersible pumps have no special requirements for well pipes and lifting pipes.
3. Mining submersible pumps have a simple structure and save raw materials.
4. Mining submersible pumps have a small volume and occupy a small area.
5. Mining submersible pumps are easy to install, do not require the construction of dedicated pump rooms, and are easy to use and maintain. The main working component of a mining submersible pump is the impeller, which is fixed on the shaft and driven to rotate by the shaft. The casing of the pump is a spiral diffuser, with the pump's suction port connected to the suction port and the drainage port connected to the drainage pipe. Before starting the pump, inject the water funnel into the pump, and then start the pump. The impeller rotates with the shaft, and the water in the impeller is also driven by the blades. Under the action of centrifugal force, water flows from the inlet to the outlet of the impeller.
During this process, both the kinetic and kinetic energy of water are increased. After the water discharged by the impeller passes through the spiral diffusion chamber, most of the kinetic energy is converted into pressure energy and then transported along the drainage pipe. At this point, due to the discharge of water, a vacuum is formed at the inlet of the impeller. The water in the suction well enters the impeller through the suction pipe under atmospheric pressure. The impeller rotates continuously, and the drainage continues. When choosing a submersible pump for mining, there are some factors that need to be considered. Firstly, when choosing a submersible pump, we must try to choose emerging high-tech products that are energy-saving and environmentally friendly, in order to completely break the limitations of traditional submersible pumps. In addition, in terms of work efficiency, faster submersible pumps should be chosen to replace traditional equipment.
