摘　　要：实时监测润滑油中的水、氧化物、金属颗粒等污染物,对风电、钢铁等行业的大型设备正常运转具有重要意义,而传统的油品传感器由于工作压力较低而使应用范围受限。设计一款高压润滑油多参数传感器,以液压油中水污染检测为例,测试该传感器在不同压力下的性能,并采用含水量0.8%(质量分数)的油液进行重复性实验。实验发现,该传感器可在0~18 MPa压力范围内工作正常,且传感器输出变化与油液压力变化具有较好的线性关系;当油液压力保持不变时,传感器输出稳定性较好;该传感器在高压环境中可以正常检测含水率的变化,且高压实验后的传感器在常压下的检测灵敏度变化小于1%,表明传感器具有较好的压力稳定性。The on-line monitoring of lubricating oil pollutants such as water,oxide and metal particles by oil quality sensor is of great significance to the normal operation of large industrial equipment.However,traditional lubricating oil sensor can not be used in many lubricating systems due to its low working pressure.A high-pressure multi-parameter lubricating oil sensor was designed,and taking the detection of water pollution in hydraulic oil as an example,the performance of the sensor under different pressures was tested.Repetitive experiments were conducted using an oil with a water content of 0.8%(mass fraction).It is found that the sensor can operate normally at the pressure range from 0 to 18 MPa,and there is a good linear relationship between the sensor output change and the lubricating oil pressure change.When the oil pressure remains stable,the sensor output has better stability.The sensor can normally detect the change of water content in high-pressure environment,and after high-pressure experiments,the sensitivity change of the sensor under normal pressure is less than 1%,indicating that the sensor has good pressure stability.
