Opis:
The paper characterises the current state of development and use of equipment and monitoring-diagnostic systems of engine cylinders and reciprocating compressors. It has presented a prototype system for monitoring and diagnostics of motor compressors of GMVH type natural gas installed in the Krio Company in Odolanów. The system monitors on-line 5 stands of motor compressors. Simultaneously 12 engine cylinders and 6 compressor cylinders of each motor compressor are indicated - a total of 90 cylinders. Driven by the need to reduce the number of monitors in the control room, aprinciple to operate the system through one monitor with the capability of immediate switching-off of a monitored motor compressor has been adopted. A charts menu provides for simultaneous on-line observation of the work of all the cylinders of a selected motor compressor. For each cylinder of both engine and compressor, against the background of the average from 16 runs and average for the cylinder's unit there are presented a few indicator diagrams, which allows for observation of the variability of a cylinder 's work, which in a spark-ignition engines can be significant. Values of main parameters ofthe cylinder's work are presented in tables and bar charts. These include: the maximum pressure of combustion and compression as well as average indicated pressures. The indicated powers are determined for the engine and compressors and a mechanical efficiency of the unit. The fiber-optic "Optrand" sensors have been used for indication, mainly to meet the need of spark-safety requirements. For the measurement of pressure, 12-bit converter cards ofown construction have been applied. Values of pressure have been sampled with angle axis pulses 0.5° crankshaft rotation. Ethernet connections were applied to transfer data between the pumping station and control room. The study characterises the main conclusions arising from past experience of system use.
