Monitoring and diagnostic

To achieve effective monitoring and diagnostics of turbomachinery, it is necessary to gather and analyze both the mechanical and aerothermal operating data from the machines. The instrumentation and diagnostics must also be custom tailored to suit the individual machines in the system, and also to meet the requirements of the end users. The reasons for this are that there can be significant differences in machines of the same type or manufacturer because of differences in installation and operation. [Pg.647]

Use of heat emissions of machinery or plant equipment as a monitoring and diagnostic predictive maintenance tool. For example, temperature differences on a coupling indicate misalignment and/or uneven mechanical forces. [Pg.696]

Fig. 18-11 Records of atmospheric CO2 in Antarctica for the past 1000 years. Open circles are ice-core data from Law Dome, on the coast of east Antarctica (Etheridge et al., 1996). Plus signs are direct measurements of CO2 in air samples collected monthly at the South Pole (NOAA Climate Monitoring and Diagnostics Laboratory, Boulder, Colorado).

At least in the power industry, the terms "monitoring" and "diagnostics" are often used interchangeably or without careful definition. Much confusion can arise when these terms are used. For purposes of this paper, these terms and the terms "expert system" and "malfunction" will be defined here. [Pg.55]

Figure 6.22. Observations of CH3CCI3 and CFC-11 from the Atmospheric Lifetime Experiment/ Global Atmospheric Gases Experiment (ALE/GAGE) and Climate Monitoring and Diagnostics Laboratory (CMDL) databases, respectively. The projections from the baseline emission scenario of WMO/UNEP (1998) are shown for comparison. The scenario includes estimated industrial production and emission for each year (including the effects of delayed release in some applications such as refrigeration, see WMO/UNEP, 1998). The methyl chloroform data show a rapid decline observed in recent years due to reduced emissions and the 5-year lifetime of this gas (Prinn et al, 1995 WMO/UNEP, 1998), while the CFC-11 abundances have just passed their peak (Elkins et al, 1993 Montzka et al, 1996 updated courtesy of J. Elkins and S. Montzka) and are projected to decline slowly in the future due to the 50-year lifetime of this gas. From Solomon (1999). Figure 6.22.

Tropospheric S - C ratios were obtained from international networks such as the NOAA/CMDL Cooperative Flask Sampling Network (National Oceanic and Atmospheric Administration/Cli-mate Monitoring and Diagnostics Laboratory) in cooperation with INSTAAR (Stable Isotope Laboratory at the Institute of Arctic and Alpine Research), the CSIRO network (Commonwealth Scientific and Industrial Research Organization) or the SIO network (Scripps Institution of Oceanography). Within these networks, tropospheric air samples, collected generally in remote areas, are analyzed for [COy] (all sites) and d C ratios (at selected sites Trolier et fl/., 1996). [Pg.255]
