High Pressure Rotary Shaft Seals
Rotary shaft seals operating under high-pressure conditions face significant challenges, including increased wear, extrusion, and leakage risks. This study presents the design, material selection, and performance evaluation of high-pressure rotary shaft seals engineered for demanding applications such as hydraulic systems, compressors, and downhole drilling equipment.
Product Description
Rotary Shaft Seals
BL-DJ complies with Meiwei FDA certification. The static ring and movable ring of the shaft seal are made of high-performance modified PTFE material, PEEK1000 and special metal processes. The shaft seal installation base, 0-ring, static ring, movable ring, and end cover can be made into partial structures, which are easy to maintain and replace. It is also used for on-site demolishing-free upgrades and replacement of equipment filler seals, skeleton oil seals and mechanical seals. The shell is a double-end heat runner.
Rotary shaft seals operating under high-pressure conditions face significant challenges, including increased wear, extrusion, and leakage risks. This study presents the design, material selection, and performance evaluation of high-pressure rotary shaft seals engineered for demanding applications such as hydraulic systems, compressors, and downhole drilling equipment. Advanced sealing materials, including reinforced elastomers and thermoplastics like PEEK and PTFE composites, are employed to withstand pressures exceeding 10 MPa while maintaining dimensional stability and sealing integrity. Finite element analysis and experimental testing confirm that the optimized seal geometry and material composition effectively minimize deformation and leakage under high pressure and dynamic loading. The results demonstrate the seal’s reliability, long service life, and suitability for harsh operating environments.
