Abstract
Hydraulic system is widely used in the ship, when the diameter of tiny particles in hydraulic oil exceeds 20μm it indicates that the abnormal wear occurred and the malfunction may cause. This paper uses the light blockage method, the microfluidic detection chip for hydraulic oil detection has been designed and fabricated, a simple and effective optical detection system is developed with the signal amplification and data collection to achieve the detection of tiny particles, and finally through the JAVA programming to count the number of particles in which the diameter is more than 20μm. The results of rapid detections on iron particles with diameter between 25μm and 38μm show the good performance of the detection system and prove that the method is feasible.
