How to make the centrifugal pump energy-saving measures (1) Improve the impeller structure, improve the impeller function, improve the pump structure, reduce the fluid energy loss in the centrifugal pump. The purpose of improving the impeller structure is to improve the flow state of the liquid in the impeller, so that the flow is stable. No eddy current, shock loss and friction loss are minimized.

The main measures for how to make the centrifugal pump energy-saving in production or selection are as follows:
How to make the centrifugal pump energy-saving measures (1) Improve the impeller structure, improve the impeller function, improve the pump structure, reduce the fluid energy loss in the centrifugal pump. The purpose of improving the impeller structure is to improve the flow state of the liquid in the impeller, so that the flow is stable. No eddy current, impact loss and friction loss are reduced to a minimum. Theoretically speaking, the more blades of the impeller, the smaller the blade thickness, the higher the efficiency of the impeller to work on the liquid. However, the more the blades, the more the liquid in the impeller The narrower the flow passage area, the greater the resistance of the fluid as it passes through the impeller: the smaller the blade thickness, the lower the strength of the blade, the easier it is to damage and the more difficult it is to manufacture. The solution to this problem lies in the ability to use it normally. , to ensure that there is enough flow channel area in the impeller and increase the number of blades.
The internal leakage of the centrifugal pump and the unevenness of the inner surface of the pump casing are also a cause of energy loss. To this end, the excessively worn population seal ring should be replaced in time to reduce the internal leakage. The flow channel is smoothed by the sanding channel. Reduce the hydraulic loss in the pump. Remove the blockages such as sand, stone and cast iron residue in the pump.
How to make the centrifugal pump energy-saving measures (2) Reduce the impeller diameter, reduce the impeller speed When the pump flow and head margin are large, and there is no smaller and more suitable pump available, you can use the turning impeller to reduce The method of the outer diameter of the impeller, or the method of reducing the speed of the impeller, to reduce the shaft power of the pump and reduce the power consumption. After the outer diameter of the impeller is cut or the impeller speed is reduced, the shaft power of the pump drops rapidly.
How to make the centrifugal pump energy-saving measures (3) Select the appropriate pipe centrifugal pump model to correctly calculate the flow and head required for the pipeline, and make the rated flow and head of the selected pump equal or slightly larger than the required flow rate of the pipeline and The lift makes the centrifugal pump work in the high efficiency area. The larger the flow rate and the head balance of the centrifugal pump, the lower the working efficiency.
How to make the centrifugal pump energy-saving measures (4) reduce the pipeline resistance and reduce the required head of the pipeline. The Bernoulli equation shows that the lift of the pump required for the pipeline is.
The feasible measures to reduce the pipeline resistance are mainly to increase the diameter of the pipe to avoid installing unnecessary valves, instruments, etc.; the pipeline should be straight and less curved as much as possible; the pipe with smooth inner surface should be used; the impurities in the pipeline should be removed in time. Materials and scaling, etc. In addition, strict implementation of the technical requirements of the centrifugal pump, maintaining the good running performance of the centrifugal pump and strengthening the daily maintenance and replacement of excessive wear parts in time, is also an important measure for energy saving of centrifugal pumps.
