Finite Element Analysis Of Rod Partial Mill Of Screw Pump Wells

The rapture and dropout of the sucker rod of screw pump has been the main problem to restrict the production of screw pumps and has affected the father application. Therefore, on the basis of sucker rod statics analysis, considering the influence of centrifugal force,sucker rod shake,lateral force produced by sucker rod contacts the pipe after its distortion and friction moment of torsion .example the use of ANSYS Software of sucker rod to establish non-linear transient finite element model, qualitative analysis of eccentric wear of sucker rod, the rationale for breaking off-line and directional well screw pump sucker rod centralizer director and quantitative analysis of the rational allocation of with a view to reduce the partial wear. therefore it is significative for scene by calculating and analysing for the model . And it can be known from practical application,can reduce deflectional abrasion if apply the calculation result of this article , prevent the pipe from rupturing , prolong period of maintenance pump .
