Deformation Characteristics of the High-Pressure Mechanical Seal Based on the Thermo-Elasto-Hydrodynamic Lubrication Model

A three-dimensional thermo-elasto-hydrodynamic (TEHD) lubrication model is presented for the high-pressure deep-grooved mechanical seal employed. The thermo-elasto deformation behaviors of the seal rings are investigated using the finite element method (FEM). The parametric studi...

Research on the transport performance of servo valve for diaphragm compressor

Abstract The oil-gas pressure differential is a key factor determining the operational reliability of diaphragm hydrogen compressors, which are critical equipment for hydrogen energy storage and transportation. This paper presents a CFD study on hydraulic oil flow characteristics...
