Halliburton 1400 Fracturing Pump Power End 3d Modeling And Failure Analysis

The research object of this paper is Halliburton 1400 fracturing pump's power end. Firstly, we have plot in practice the Halliburton 1400 fracturing pump's power end. Then, we have set up the three-dimensional entity's model of its part on the basis of plotting by utilizing the mechanical automatic software Pro/ENGINEER, and finished the local and global assembly of Halliburton 1400 fracturing pump's power end according to its concrete constraint.Secondly, the paper has carried on the comparatively detailed argumentation to this comprehensive discipline technology of mechanical failure analysis, According to the failure modal which Halliburton 1400 fracturing pump's power end part appears, the paper have discussed specifically two kinds of failure form, namely, fracture and wearing. Finally, on the basis of above mentioned narrations, the paper has studied in detail the failure part: splined shaft, linking bolt, worm gearing. Through thorough analysis and research, the splined shraft fracture is typically fatigue rapture according to the macrography and micrography analysis of fracture. The rapture of the splined shaft is caused by the undersize round value. At the same time, we have found the place that the stress concentration and fatigue life is minimum by utilizing software is where the rapture lies; for linking bolt, we have concluded that the main reason leaded to all bolt fracturing is that the fix position is unreasonable, except that their material is not up to standard; the last part failure analysis of the paper is worm gearing. It is confirmed that the reason leaded to the worm gearing's surface serious wearing is mainly that the hard particle of the tin bronze material can not be distributed evenly. This results in the sticking wearing predominatingly, and together with the other wearing failure.
