The Research on Enhancing the Pressure Bearing Capacity Of The Hydraulic end Of the Reinjection Pump
The hydraulic end of the cuttings reinjection pump is prone to fatigue cracking,and the maintenance cost is very high.Under the condition of high pumping pressure,the peak stress in the hydraulic end of the cuttings reinjection pump is relatively large,and the junction of the discharge hole is easy to crack,resulting in a short service life of the cuttings reinjection pump.Therefore,the static analysis of the fluid end is carried out by using ANSYS software,and it is found that;Under discharge condition,the intersecting area of pump head body is a stress concentration area,and the maximum stress value is 725MPa.After optimization with FACET modification technology,the maximum stress value is reduced to 636MPa.
