The lifeblood of an automotive engine is oil and its circulation. Subtle defects in the oil pump can and will result in after sale (Warranty) defects with serious cost and image consequences. Sciemetric's Signature Analysis System with InspeXion now offers an ideal platform to identify such defects "upstream" prior to engine installation.
High-speed data capture of pressure combined with simultaneous time and frequency domain (FFT) analysis allows InspeXion® to quickly "learn" normality of the pump family currently under test. 3s "envelope" bands provide the first and simplest level of defect detection. Additional pre-configured Signature Analysis "tools" are then applied to find the more subtle "needle in the haystack" type defects, which directly affect ultimate engine quality.
Since the pump is monitored directly out of the machining department, time and frequency domain analysis of the discharge pressure quickly identifies potential tool set up and wear problems.
Trended shifts in the data provide an early warning for adjustment of tooling thereby eliminating any added downstream embedded costs.
