Title: Innovations of Cheng-Kang Guan in Mechanical Seals

Introduction

Cheng-Kang Guan is an accomplished inventor based in Murrieta, CA (US). He has made significant contributions to the field of mechanical seals, particularly with his innovative designs that enhance performance in high-pressure applications. His work is characterized by a focus on reducing fluid pressure and viscous heating, which are critical factors in mechanical seal efficiency.

Latest Patents

One of Cheng-Kang Guan's notable patents is the "Shock Wave Mechanical Seal." This invention features an end face mechanical seal designed for high-pressure, compressible fluids. The seal includes metal or ceramic faces separated by a gap that contains at least one supersonic region. This design accelerates the fluid in the leakage direction, producing a shockwave that effectively reduces fluid pressure, thereby minimizing viscous heating and the length of the gap. The choke width of the seal gap is meticulously engineered to be between 50 and 200 micro-inches, with flat upper and lower boundaries and combined slopes of less than 10 degrees. The total length of all supersonic regions is kept under 0.1 inches, and a non-supersonic region is included to further reduce fluid pressure by inducing viscous stresses. The seal can be configured axially or radially and can serve as a pre-conditioner in conjunction with a conventional downstream mechanical fluid seal.
