This case study describes bearing damage detected through online measurements taken from a ball mill at the flotation plant of Asarel Medet AD in Bulgaria. At the beginning, the SPM HD trend had varying shock pulse levels...
Overall vibration catches bearing damage very late, when there may be 0.1% of the bearing lifetime left. Traditional vibration, let’s say systems with poor signal-to-noise ratio...
A gear pump was used in a plastic extruder, where the gear’s head pumps the plastic mold from the barrel into the pelletizer. The extruder was already fitted with a condition monitoring system, but in early 2016 our customer decided...
The support wheel bearings in a calciner case had an ultra-low rpm: 3.4–3.9. The customer had been utilizing a traditional vibration analysis system for a number of years, but they lacked a pre-warning time and faced high risk…
This case involves a new installation at a site that does their own condition monitoring, and they noticed high vibration of 20 mm/sec. We captured the data and used motion amplification...
The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are...
