Abstract
The performance and service life of the plunger and seal of fracturing pumps directly affect the implementation of fracturing technology. The structure characteristics of the plunger seal pair in OPI-1800AWS fracturing pump are analyzed. This paper focus on the contact stress between the plunger and the sealing ring, and the effect of the sealing ring structure parameters on the contact stress is analyzed, and the structure of the sealing ring is optimized. The failure and leakage reason of the plunger seal pair is analyzed. A new structural renovation plan for the plunger seal pair in fracturing pumps is put forward, that is, the sealing effect and service life of the plunger and seal can be increased by strengthening the plunger surface, selecting excellent sealing materials, improving the structure of the sealing ring, adding scraping ring, keeping the moving track of the plunger and the axis of the cylinder jacket in line.
