Research And Application Of The Precise System On Pneumatic Measurement

This issue comes from the requirement of produce in some refrigerator compressor factory in Huangshi. This paper studied mainly mechanism about pneumatic sensor of small measurement range linear dimension measurement in pneumatic measure system concluding static stage and dynamic state characteristics study. The author wish this study win be used in the development of numerical control dividing lathe that can divide into groups of the size for precise measure of thickness of ompressor carboy hatch soft shimThe system of pneumatic measure applied widely for component measurement in produce process in factory .The author 100kup a large number related documents over about one and half year for research and went to factory and related research institute for investigating. The author has done a good deal of theoretical calculations and experiments base on related pneumatic measure theories. This paper deriving the theory work inflection point in the static stage characteristics curve of small measurement range linear dimension measurement .by the way of high pressure and back pressure pneumatic measure and designed the parameter of the mainly and measure spray head ,which are the key component in the spray head-baffle pneumatic sensor .The different groups for the main-spray head and the measure spray head ,will effect the dynamic and static stage characteristic parameter .The author have done contrast experiment and optimization design to test and verify the theory derivation whereby made the rang of show valve of pneumatic measure system measure range up to 40 u m,the sensitivity up to 100mv/ u m,resolution up to 0.05 P m,the uncertainly of measure is less than 0.O2 u m,satisfaction of requirement of groups the carboy hatch thickness size precise measure of soft shims. This paper provide the theory base and technical guidance for the intellect measure system that the design with the core component of pneumatic sensor by computer to gather and handle data,to analyze error and auto-display.
