Vibration Ppt - authorSTREAM Presentation. APPLICATION APPLICATION Accelerometers are also used for machinery health monitoring to report the vibration and its changes in time of shafts at the bearings of rotating equipment such as turbines, pumps,fans,rollers,compressors , and cooling towers.
2020-5-17A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near ...
Written by Jerome Jennings, global product manager, SPX Cooling Technologies, Inc. Industries that require process heat rejection often use field-erected cooling towers to keep pace with their heat load. Cooling towers have large fans and powerful motors, which can present a host of challenges, including excessive sound, vibration and expense.
Shaft and bearing vibration monitoring is specified in the ISO-7919 and ISO-10816 norms respectively and is applicable to any rotating machines such as hydro turbines, gas turbines, steam turbines, pumps, fans, cooling fan towers,...
The range does not represent the cooling tower capability rather, the range is based on the cooling-water circulation flowrate L in, and the sum of the heat loads taken from the heat exchangers in the process unit Q, and it is not related to the size or capability of the cooling tower. On the other hand, an increase in range will cause ...
Cooling water may be recycled through a re- circulating system or used in a single pass once-through cooling OTC system. Recirculating systems may be open if they rely upon cooling towers or cooling ponds to remove heat or closed if heat removal is accomplished with negligible evaporative loss of cooling
In cooling towers, cycle of concentration is a ratio that measures how concentrated solids are in the cooling tower process water compared to the makeup water by measuring conductivity in the blowdown. A facility should see at least three to three to six cycles of concentration which is three to six times the concentration of solids in the ...

2015-3-13D. Cooling Towers Hot water from the condensers is passed to cooling towers in which atmospheric air circulates in direct contact with warmer water the heat source and the water is thereby cooled. Water, acting as the heat-transfer fluid, gives up heat to atmospheric air, and thus cooled, is re-circulated through
MC Monitoring SA offers PPT-080 - Proximity Probes Transmitter and other solutions for the Energy Monitoring and Testing
Cooling water systems involve multiple pieces of mechanical equipment, such as cooling towers, heat exchangers, pumps, piping, and other process specific equipment. A typical recirculating cooling systems components may also consist of pre-treatment facilities such as coagulation and filtration, and even as extensive as using reverse osmosis ...
