Basic definition and working principle of slurry pump
A slurry pump is a specially designed centrifugal pump primarily used for transporting liquid mixtures containing solid particles. Its working principle is to convert electrical energy into kinetic and potential energy of the medium through the rotation of the impeller, using centrifugal force to effectively transport the mixture of solid particles containing slag and water to the designated location.
working principle
During the operation of the slurry pump, the liquid is thrown towards the outer edge at the center of the impeller and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the snail shaped pump casing, the liquid slows down due to the gradual expansion of the flow channel, and converts some of its kinetic energy into static pressure energy. Finally, it flows into the discharge pipeline at a higher pressure and is sent to the required location.
The role of slurry pump in the turbid circulating water system of steel rolling
major function
The slurry pump is mainly responsible for transporting slurry containing high concentration slag in the turbid circulating water system of steel rolling. These slurries typically come from a mixture of wastewater and solid particles generated during the rolling process. The effective operation of slurry pumps is crucial for maintaining the continuity and production efficiency of steel rolling production lines.
Application scenarios
Converter dust removal water: helps to remove dust and wastewater generated during converter operation.
Blast furnace gas washing water: used to clean the particles carried in blast furnace gas.
Continuous casting turbid circulating water: used to transport solid particles in cooling water during the continuous casting process.
Structural characteristics and maintenance of slurry pump
Structural characteristics
The structure of slurry pump mainly consists of three parts: pump head, bracket, and shaft seal. The pump head adopts a double-layer pump casing design to improve the strength and durability of the pump body. The bracket structure optimizes the service life of the bearings, while the shaft encapsulation effectively prevents air from entering the pump and a large amount of water from leaking out of the pump.
Maintenance points
In order to ensure the normal operation and prolong the service life of the slurry pump, regular inspections and maintenance are necessary. This includes checking the sealing between the pump body and pump shaft, as well as regularly replacing severely worn components.
Performance parameters and selection of slurry pump
performance parameter
The performance parameters of slurry pumps include flow rate, head, efficiency, and material. These parameters determine the applicability and efficiency of the slurry pump under different operating conditions. For example, the design of the KSQ submersible slurry pump enables it to adapt to the transportation of high concentration solid-liquid mixtures, with a solid-liquid mixture concentration of up to 60%.
Selection considerations
When choosing a slurry pump, it is necessary to consider its performance parameters, structural characteristics, and application scenarios. For example, for the turbid circulating water system of steel rolling, a slurry pump with high wear resistance and high efficiency should be selected to meet the demand for high concentration slag transportation.
In summary, the slurry pump plays a crucial role in the turbid circulating water system of steel rolling, and its efficient and stable operation directly affects the efficiency and product quality of the entire production line. Therefore, regular maintenance and reasonable selection are key to ensuring the long-term stable operation of slurry pumps.
