Space Tribology for Turbo Pump Seal

Research object

 Ultra-high pressure sealing (sealing) technology

 

 Over 100 bar high pressure pump leads to instability of the whole system by abrasion (wear) of the seal due to the leakage (leakage) in reduced efficiency of the problem itself, and high-speed rotation. Self-injection type swirl Station (Anti-swirl) resolved by applying sealing technology High-speed seal design technology. Apply the problems of high-speed rotation of the dynamic pressure sealing unit and complementary

 

 Optimized design technology for securing kinetic stability

 

 That the vibration of the high reliability of the fluid machine (vibration limits (overall): 3.0 mm / sec RMS) to achieve it for the design phase from the kinetic stability design review (API 610 8th edition standard; DRAFT INTERNATIONAL STANDARD ISO / DIS 13709)

 

Our major experiences with high pressure sealing unit are followings ;

- Design and Analysis of pressure distribution in the seal film.

 - Leakage performance of High Pressure Seals

 - Dynamic Coefficients and Stability of Seals

 - Performance Test

 - Durability Test for Materials

 

Application

- All Turbo-machinery and Rotating Mechanism (Pumps, Turbine (Gas, Steam), etc.)
