AI Technical Summary
Existing dry-running piston compressors face excessive friction and high temperatures at high piston speeds, significantly reducing the service life of sealing rings due to high frictional stress.
A piston rod sealing device with a stuffing box assembly, comprising a stuffing box and stuffing box sleeve made of different materials with matching thermal expansion coefficients, supported by spherical elements and tilting rings, allowing a frictionless annular gap seal for piston rods, compensating for misalignments and movements without significant force.
The solution provides a low-friction, long-lasting seal suitable for high-pressure environments, maintaining a consistent leakage flow and reducing the need for special cooling, thus extending the service life of sealing components.
