【摘要】：提出了一種液壓油污染物多參數(shù)測量傳感器,該傳感器在平面型微流體電感傳感器基礎(chǔ)上增加了一個單層電感線圈,并將兩個單層線圈正對排布在直微通道兩側(cè),在電感參數(shù)檢測的基礎(chǔ)上將兩個單層電感線圈等效為一對圓環(huán)形電容極板,引入了電容參數(shù)檢測,從而實現(xiàn)了對液壓油中鐵磁性金屬顆粒、非鐵磁性金屬顆粒、水滴和氣泡4種污染物的檢測。對該多參數(shù)傳感器進(jìn)行了設(shè)計,并結(jié)合仿真和實驗對檢測位置進(jìn)行了優(yōu)化,電容參數(shù)檢測實驗實現(xiàn)了液壓油中180μm水滴和240μm氣泡的區(qū)分檢測;電感參數(shù)檢測實驗實現(xiàn)了液壓油中80μm鐵顆粒和150μm銅顆粒的區(qū)分檢測。該研究對液壓油多污染物的區(qū)分檢測提供了一種新方法。
[Abstract]:A multi-parameter sensor for measuring hydraulic oil pollutants is proposed. The sensor adds a single layer inductance coil to the planar microfluid inductance sensor, and two single-layer coils are arranged on both sides of the straight microchannel.Based on the detection of inductance parameters, two single-layer inductance coils are equivalent to a pair of annular capacitor plates, and the capacitance parameters are introduced to realize the measurement of ferromagnetic metal particles and non-ferromagnetic metal particles in hydraulic oil.Detection of water droplets and bubbles.The multi-parameter sensor is designed, and the detection position is optimized by simulation and experiment. The detection of 180 渭 m water drop and 240 渭 m bubble in hydraulic oil is realized by capacitance parameter detection experiment.The inductance parameter detection experiment has realized the distinguishing detection of 80 渭 m iron particles and 150 渭 m copper particles in hydraulic oil.This study provides a new method for the detection of multi-contaminants in hydraulic oil.
