ABSTRACT
Oilfield pumps occupy a special place in the structure of the complex of equipment used in the drilling of oil and gas wells. It is established that the plunger-bushing assembly is the most vulnerable pair and the failure rate of the pump is largely determined by the failure of this particular node. In order to improve the efficiency and service life of the pump, it is proposed to process the inner surface of the bushings on a laser installation with Cu, Fe, Al nanoparticles. Based on numerous experimental studies, the optimal number of nanoparticles and the technological mode of their application are proposed. It is established that with a decrease in the size of nanoparticles, the hardness of the hardening surface increases many times. This can be explained by the fact that the deformation of the material is caused by the movement of dislocations, while its intergranular boundaries act as a surface against the movement of dislocations.
Keywords: Plunger-bushing pair, nanoparticle, deformation, surface hardening.
