Study on the Feasibility of Reducing the Weight and Extending the Life of Fracturing Pump Fluid Ends
As a high value consumable part,the fracturing pump fluid end of the fracturing pump is widely used in China to process the entire large-scale forged billet.There is a lot of material waste in the manufacturing process.According to the structural characteristics of the fracturing pump fluid end,the failure characteristics of the fracturing pump fluid end were analyzed.It is confirmed that as long as the structural strength is guaranteed,the weight of the valve box forging material can be reduced as long as the stress concentration degree at the easy cracking position is effectively reduced,and even the fatigue life of the fracturing pump fluid end can be extended.According to the analysis,a combined modular fracturing pump fluid end structure was proposed,and the issues to be considered in the design of the combined modular fracturing pump fluid end were put forward.The relevant situation of the combined modular fracturing pump fluid end prototype in the field test is presented.This study not only has theoretical guidance significance,but also practical significance and economic value for the weight reduction and service life extension of fracturing pump fluid ends.
