根据高梯度磁力分离技术原理设计了一种检测润滑油或液压油中铁磁性磨粒的仪器———铁磁性磨粒检测仪。通过试验确定了磁滤器的合理参数,并验证了其重复性;设计确定了合适的霍尔传感器及后续处理电路。
According to the principle of high gradient magnetic separation technology, a kind of equipment for detecting ferromagnetic abrasive grains in lubricating oil or hydraulic oil is designed --- ferromagnetic abrasive grain tester. Through the experiment, the reasonable parameters of the magnetic filter were confirmed and the repeatability was verified. The suitable Hall sensor and subsequent processing circuit were designed.
