Application of new repair technology in the restoration of plungers of borehole rod pumps

The durability of oilfield equipment (OFE) depends on a number of factors, including the reliability of the design, the perfection of their manufacturing technology, the level of use of modern technologies in repair and restoration and other works. When restoring machine parts whose service life has expired, modern methods such as laser, ironing, flame gas, etc. are currently used in repair production, which create the basis for a serious impact on their resources. Of great importance is the technology of restoring parts - the method of ironing. In the processes of restoration of large-sized, cabinet, metal-intensive parts, etc. The article presents the results on increasing the resistance of the plunger-cylinder pair to abrasion and increasing the service life due to the use of ironing technology. Keywords: rod depth pump; abrasion resistance; plunger; cylinder; ironining.
