The method of calculating the lobe wall thickness of cuff cylinder piston seal

Abstract

The presented article describes a method for calculating the wall thickness of the lip seal lobe in the ANSYS Workbench Mechanical software package. The main problem that designers face when choosing the wall thickness of the lobe of cuff seals for reciprocating compressor units operating without lubrication is described. As a result of the work, the maximum and minimum wall thickness are calculated for the materials most common in oil-free compressor units. Antifriction materials of the
Flubon and Fluvis groups containing up to 20 % carbon fibers have the smallest wall thickness in all pressure ranges considered. At the same time, the results obtained allow us to speak about the low efficiency of cuff seals with a maximum wall thickness at pressures below 1 MPa.
