Novel dual synergistic sealing ring design for a high-pressure pump – Part II

Abstract

As simple, small, low-friction and low-cost sealing elements, O-rings are widely used in various types of pumps. When a pump's inner pressure increases, the risk of O-ring failure rises concurrently. The numerical calculations discussed in this article have been done to analyse the mode and root cause of the failure of an O-ring that is installed in a high-lift pump. A novel, dual sealing-ring design is also described.
