There are many different styles of steam traps but they all serve the same basic purpose; to automatically allow condensed and non-condensable gases like air to escape while maintaining an efficient thermal transfer process. Most traps function while remaining closed to live steam but some use simple control valves to pass steam at a regulated rate.
Compressed air is one of the three highest cost utilities in use at your plant. It is also one of the least maintained in terms of system leaks. Leaks are expensive and wasteful, but most often ignored.Like compressed air leaks, vacuum leaks can cause grief for manufacturers who rely on negative pressure for their processes. Vacuum leaks represent energy waste, but they also affect product quality.
Lubricating bearings based on their condition, rather than time in service, is the best way to optimize greasing at your facility. Condition based lubrication programs rely on ultrasound data collection to alarm when re-greasing is required. Techs re-lubricate bearings with an ultrasonic grease gun interface to ensure the right amount of grease is added.
Monitoring bearing condtion with ultrasound shows us evolving trends in friction levels, random impacting, rubbing, spalling, and other defects at the earliest stage of failure. In most cases ultrasound will reveal the onset of failure long before they show up in vibration analysis reports and thermal imaging surveys.
Corona discharge, arcing, tracking, damaged line bushings, and other potentially dangerous and wasteful conditions in high voltage systems produce ultrasound as a warning of future failure. By itself, or as a compliment to Infrared Imaging, Ultrasonic Detection has become the technology of choice for electrical inspections of ...
Ultrasonic tightness testing is done by placing an ultrasound transmitter inside the test volume and then scanning the seal points (doors, windows, vents, etc...) with the ultrasonic receiver. Leaks are identified by an abrupt increase in ultrasound levels as the inspector passes over the seal area.
