Research And Realization Of Portable Electrical Submersible Pump Units Speed Measuring Instrument

In this paper a portable submersible oil pump unit speed measuring instrument is designed to work for the submersible electric pump unit speed measurement. It based on high-speed SoC microcontroller C8051F. The following several aspect work has been completed in this paper.1. A data processing method is proposed to use the chirp-z transformation to improve the precision, through the study of the basic work principles of submersible electric pump unit characteristics, and according to the (submersible) electric pump vibration signals when it worked. And it has made the principle analysis to chirp-z in this paper.2. The light electrical measurement electric circuit and vibration test circuit is designed through the structures test platform, in order to verify the accuracy of vibration test algorithms and measurement accuracy.3. A microcontroller C8051F005 is designed in this paper as the core data acquisition system. The system made full use of C8051F005 12 high-speed A/D acquisition module, and could make a three-dimensional vibration signals collection. PC use VB to prepare man-machine interaction contact surface, and realize submersible pump speed automatic measurement. In this case, it can facilitate the conduct of control, and the vibration signals can be complex spectral analysis, which greatly reduced the workload of the staff, greatly improving the efficiency and enhanced the level of industrial automation.It can be showed that the system is very reasonable on software and hardware design through the industrial field tests, and it has better vibration data acquisition and analysis functional and has a better measurement of precision, simple operation, compact structure, and it can meet the scene of various vibration analysis of data collection requirements.
