Abstract

The invention relates to an impurity particle detecting sensor testing device and method. The device includes a liquid circulation pipe (12), a particle injection port (13) and a bubble generating device, wherein the test liquid (5) flows in the liquid circulation pipe (12), the particle injection port (13) is used for injecting impurity particles (6) with known target parameter values into the test liquid (5), and the bubble generating device is used for generating bubbles in the test liquid (5) to detect parameter values of the target parameters of the impurity particles (6) flowing along with the test liquid (5) in a bubble state and a bubble-free state by a to-be-tested sensor (31). The device is advantaged in that the bubbles can be generated in the test liquid, the actual working environment of the impurity particle detecting sensor can be more realistically simulated, and thereby the detection result of the sensor on the impurity particles is more realistic, and higher accuracyis realized.

Description

technical field [0001] The invention relates to the technical field of sensor performance detection, in particular to a sensor testing device and method for detecting impurity particles. Background technique [0002] As an important component of the aero-engine health management system, the lubricating oil metal chip sensor is used to monitor the size and weight of metal and non-metallic particles in the lubricating oil pipeline, so as to measure the mechanical loss state of the engine, evaluate the probability of failure, and achieve Early warning. In the process of R&D and design of the sensor, testing equipment is needed to simulate the detection test of the sensor in the installed state. By obtaining the test data, the characteristics of the sensor can be optimized and error correction can be performed to improve the dynamic detection performance of the sensor. [0003] Lubricating oil and metal chips sensor is a new type of special sensor. In addition to being installe...
