Diagnostic method for analyzing and monitoring the process parameters in
the operation of reciprocating equipment
Abstract:
The method of the present invention utilizes a microcomputer in combination with a CRT and a multiplicity of transducers for monitoring process parameters in the operation of a reciprocating device having a linear stroke. A profile of the process parameters including pressure and velocity are generated as a function of stroke length and time and are stored in a non-volatile memory and graphically displayed on the CRT as master traces for comparison with current data profiles. The velocity is calculated by dividing distance transversed with time or by use of a velocity position transducer.
