摘要

光阻法液体颗粒计数器已广泛应用于液压、电力、医药和环境等领域，但在实际使用中，对于形状不规则颗粒，由于光以不同方向照射颗粒产生的投影面积不一致，会影响测量结果准确性和重复性。本文设计了一种基于光阻法的双光路液体颗粒计数器，垂直交错的双光路检测结构可以获得颗粒不同方向的粒径信息，改善投影面积不一致的影响。同时，考虑到样品浓度对重合误差的影响，根据最大颗粒浓度和检测范围对传感器传感区尺寸作出限定。此外，针对样品颜色不同影响光电探测器输出基准电压的问题，引入反馈机制以调节光强使基准电压稳定，并通过70

m球形颗粒脉冲信号的模拟和实测，分析了流速对脉冲信号的影响。

Abstract

Light-blockage liquid particle counter has been widely applied in the field of hydraulic pressure

electric power

medicine and environment etc. In practical application

however

an impact will be exerted on the accuracy and repeatability of measurement due to the phenomenon that particles with irregular shapes

under light irradiation in different directions

will produce different projected area. In this paper

a dual optical-path liquid particle counter based on light blockage is designed. Vertical and interlaced dual optical path detection structure can help to obtain the size information for particles in different directions and improve the result of inconsistent projected area. At the same time

considering the impact of sample concentration on coincidence error

sensing area of the sensor is defined in accordance with the maximum particle concentration and detection range. While in consideration of the problem that different color of the samples will affect output reference voltage of the photoelectric detector

a feedback mechanism is introduced to adjust the light intensity for stabilizing the reference voltage; and an analysis on the impact of flow rate on pulse signal through a simulation and actual measurement in the 70

m spherical particle.
