Rider rings and Piston sealing

The automated pV diagram analysis is one of the most important methods for evaluating the condition of piston sealing rings. For the detection of leaking piston sealing rings on a double acting cylinder. Feature The automated pV diagram analysis is one of the most important methods for evaluating the condition of piston sealing rings. For the detection of leaking piston sealing rings on a double acting cylinder, the two neighbouring compression chambers are analyzed in parallel. The vertical position of the piston is an important indicator for wear of the piston rider rings. For effective long-term wear monitoring, a wear indicator configuration tool is required to allow a correct adjustment of the measurement parameters at all times, e.g. after disassembly of the displacement sensor.
