The report describes the device power, created on the basis of the thermoelectric effect. The Peltier module of the generator type is used as the main element of the conversion of thermal energy into electrical energy. The structure of the generator system being developed, the results of testing the individual Peltier element and the test tests of the assembled power supply are described.
Data measurement system of compressor units defect diagnosis by vibration value. In this paper are studied analysis and control algorithms of vibration signals. An overview of the vibration diagnostic tools is presented. Software for data of vibration parametrs receiving, processing and storing was designed.
In the article we research the means for fault detection system set up for NGV-refuelling stations compressor equipment. It is a real-time diagnostics while operation. Equipment technical state is estimated in accordance with vibration index analysis. The fault detection system helps to vary frequency till fifteen harmonic components of generated signal and vibration acceleration and gives opportunity...
The paper describes the way to get a useful component of the ultrasonic defectoscope signal at high-rise reverberation and noise interference. The useful component is got with the thresholding of detail factors of a wavelet-decomposition. Probability of the 1st and 2nd type mistake is examined.
In the report the technical solution to the problem of diagnosis compressor installation of NGV filling stations is reviewed. The correspondence between the frequency ranges that characterize the defects and levels of wavelet filter is established. The algorithm allows you to set the amplitude of the harmonics and diagnose the problem.
