Analysis of Influencing Factors on Friction Resistance of Pump Pipe Section of Geothermal Water Extraction
摘要
Abstract
In order to analyze the factors affecting the friction resistance of the pump section in the process of geothermal water pumping and determine the min-ing parameters of safe,efficient and energy-saving geothermal water pumping,the analysis model of the factors affecting the pressure loss of geothermal water pumping was established,and the influence of flow rate,velocity,pipe diameter and pipe length on the pressure loss was calculated respectively.The results showed that under normal production conditions,the friction resistance of the pump pipe section decreased with the increase of the inner diameter of the pump pipe at different flow rates,and finally gradually ap-proached zero.The frictional resistance changed expo-nentially with the flow rate and increased with the flow rate,and the increase rate also increased with the flow rate.The reasonable length of the pump pipe was the premise of ensuring the healthy and safe operation of the equipment.The size of the friction resistance in the pump pipe was linear with the length of the pump pipe.The longer the length of the pump pipe flowing through the geothermal water,the greater the friction resistance.According to the research results,the optimum mining flow range of different types of pump tubes was recom-mended,which had a high guiding significance for se-lecting the pump tube type,determining the best pro-duction parameters and ensuring the safe and energy-saving production operation of the project.关键词
