Mine submersible pump structure diagram interpretation

Through the analysis of mining submersible pumps we can understand that the main use of mining submersible pumps in the cause of the coal mine, not only for the drainage of coal mines, coal mine rescue, as well as the drainage of the mine complex . With the further improvement of coal mine safety requirements nowadays, the research and development of mine submersible pumps have great significance for the development of coal mine in our country. Mining submersible pump structure research has become increasingly important. Mine submersible pump structure diagram Interpretation 1, the pump wheel: work wheel according to the number of suction port can be divided into single-sided water and double-sided water. In the structure of the work round can be divided into closed and open. Centrifugal pump enclosed single-sided water more work round. Open-type working wheel used for sewage pump or sand pump, the open roadway covered by the front cover of the pump, the front cover can be removed to remove dirt and blockage on the leaf road. 2, the other circulation parts of the pump: rotating working wheel to its inhalation of water to a great speed to the surrounding discharge. The role of stationary flow-through parts is to bring these currents together, direct them and reduce their speed into the drain pipe or the next working wheel. In order to pump to obtain higher efficiency, water flow should be avoided in the fixed part of the impact occurred, eddy current, and gradually reduce the speed, variable pressure static pressure. 3, screw shell: screw shell pump shell such as snail-shaped. The speed of the flow coming out of the work wheel decreases when it enters the spire, while the cross section of the spire gradually enlarges to collect all the water flow, and finally the water is discharged again by the diffuser lowering the speed. 4, the deflector: pump deflector also called the guide wheel, mounted on the outer circumference of the work, above the proliferation of flow channels, and out of the work by the flow of water out of line. Deflectors are commonly used in segmented centrifugal pumps. The water discharged from the working wheel enters the deflector, where it is diverted to the return runway and finally to the next working wheel. The water discharged from the last working wheel is introduced into the spiral through the deflector, and then flows into the diffuser pool to lower the velocity again and feed it into the drainage pipe. Mining submersible pump is a kind of working turbine. Mining submersible pumps are commonly used in D-type, DA-type and TSW-type multistage centrifugal pumps; while the bottom hole pits and mining area drainage are commonly used B type, BA type and BZ single-stage centrifugal pump. Because of its variety, its characteristics are also slightly different, after years of development, its species are constantly expanding. A more thorough analysis of its structure can not only improve the competitiveness of the product but also improve the productivity of the product.
