The working principle of a large number of products are one of the users are very concerned about where care is often through the instructions and other knowledge to understand how to use a product. It is a special product for a submersible pump, because it does not work on the ground, but in water, so it's more important to understand how well submersible pumps work. Wells with submersible pumps working principle Interpretation Well submersible pump with the main working principle: 1, the impeller is driven by the pump shaft rotation, located between the blade fluid doing work, the fluid by the centrifugal force, thrown from the center of the impeller to the periphery. When the fluid reaches the periphery of the impeller, the flow rate is very high. 2. The pump housing collects liquid thrown out from the blades. These liquids flow in the direction of the volute-shaped passage gradually expanding in the housing to convert the kinetic energy of the fluid into static pressure energy and reduce the energy loss. Therefore, the role of the pump casing is not only to pool the liquid, it is more an energy conversion device. 3, the principle of liquid absorption: rely on high-speed rotation of the impeller, forcing the center of the impeller liquid is thrown away at a high speed, resulting in low pressure in the center of the impeller, the lower tank liquid is therefore continuously suction. 4, the outer circumference of the impeller mounted guide wheel, so that the liquid pump energy conversion efficiency. The guide wheel is a fixed, bladed ring located on the periphery of the impeller. The bending direction of the blade is opposite to the bending direction of the impeller blade, the bending angle of the blade matches the direction that the liquid flows out from the impeller, guiding the liquid to change direction smoothly in the passage of the pump casing so as to minimize the energy loss and convert the dynamic pressure energy into High static pressure energy. 5, balance hole on the rear cover to eliminate axial thrust. The pressure of the liquid leaving the periphery of the impeller is already high and some of the liquid will seep to the rear of the impeller rear cover and the liquid inlet at the front of the impeller is under pressure and thus produces an axial thrust pushing the impeller to the pump inlet side. 6, shaft seal device to ensure the normal use of submersible pumps, efficient operation. Well submersible pump at work is the pump shaft rotation and the shell does not move, during which the ring gap if not to be sealed or seal is not good, the outside air will infiltrate the low pressure area of ​​the impeller center, so that the pump flow, efficiency decreased. In general, a mechanical seal or a packing seal can be used to achieve a seal between the shaft and the shell. Through the above 6:00 analysis, we can already very clearly understand the working principle of submersible pump wells, it is a compact structure, small size, light weight, easy installation, easy to use, high efficiency, energy conservation, etc. Advantages of the product. Further research on such products is of great significance to enhancing the competitiveness of products.
