Finding Dust Ingress on Diesel Engines with Ultrasound Inspection
Finding leaks in air intakes and turbo chargers on diesel engines can be a difficult task. Dust contamination in the engine oil was reported by oil analysis lab results. One mining company discovered that ultrasound is a fast and simple way to pinpoint invisible leaks. By placing a 200mw ultrasonic transmitter in the inner air filter and resealing the breather system they were then able to inspect the engine and filter system with an SDT270 ultrasound detector. They immediately found leaks that 8 hours of visible inspection were unable to find.
This practice became a mandated preventive maintenance procedure on every asset in the mobile fleet. Accounting reported an 8 million dollar savings from premature engine failures and lost production within the first 6 months.
