摘要： The present invention is directed an ultrasonic frequencies fault detecting apparatus. The present invention uses high frequency ultrasonic energy signals to analyze bearings and determine the presence of faults therein. The ultrasonic return signals are heterodyned (by amplitude demodulation) into the audio spectrum for purposes of audio detection. In addition, a FFT spectrum of the signal is displayed on a monitor for more accurate results. According to the present invention software is used to automatically analyze the FFT spectrum by comparing the current spectrum with stored spectrums of known bearing conditions as modified based on the rotary speed of the bearing and the number of balls. Once a defect in a bearing has been located in this manner using automated FFT analysis, an operator can then use a device, such as a calibrated lubricant dispenser, to effectuate maintenance and/or repair.

摘要： A lubrication dispensing apparatus for lubricating a device with moving parts includes a lubricant reservoir, a lubricant dispenser for dispensing lubricant from the lubricant reservoir, an ultrasonic detection module which detects the amplitude of ultrasonic energy emitted by said device when its parts are moving and produces an signal related thereto, and a control module which analyzes the amplitude of the signal from the ultrasonic detection module and, in response to a lubricate signal, causes the lubricant dispenser to automatically dispense lubricant onto the moving parts of the device until the signal from the ultrasonic detector indicates that the ultrasonic energy produced by the device has decreased to a particular level. The control module includes a programmed processor and a storage memory. The memory stores as a base value the value of the detected amplitude of ultrasonic energy when the device is operating properly. After receiving a signal to lubricate the device, the processor causes the dispenser to start the flow of lubricant to the device, compares the signal from the ultrasonic detection module when the parts are moving to the base value, and causes the dispenser to cease the flow of lubricant when the signal substantially decreases.

摘要： A system and method for eliminating confusion associated with checking valves, wherein additional test points are added to the measurement of a valve for ensuring the verification of the actual sources of leaks or turbulence. A base line measurement for the valve is established by measuring the level of ultrasonic sound at the two points upstream from the valve. The level of the ultrasound at two downstream points is then measured. The value of the ultrasound at the downstream test points is compared to the values of the ultrasound at the upstream test points. If the values of ultrasound at the downstream test points are higher than the values of the ultrasound at the upstream test points, then the valve is leaking. If the values of the ultrasound at the downstream test points are close to or lower than the values of the ultrasound at the upstream test points, then the valve is not leaking, i.e., the valve is good.

摘要： A method and apparatus for detecting leaks and mechanical faults by way of an ultrasonic device. An output from a variable gain amplifier is supplied to a pair of heterodyning circuits, i.e., a dual heterodyning circuit. At each respective heterodyning circuit, the output signal from the variable gain amplifier is multiplied by a local oscillator that is internal to each circuit. The dual heterodyning circuit is used to provide an enhanced input transducer signal for spectral analysis. This permits the capture of low level frequency components for extraction during spectral analysis. The dual heterodyning circuit of the present invention to provide the enhanced spectrum to thereby permit an easy determination of whether the resonance is mechanical or electrical becomes clear. In addition, fault frequencies are also more easily discernable. In other words, the enhanced signal output provides a lower signal to noise ratio such that the ease with which frequency components are analyzed is increased.
