摘要
目前矿用自卸车液压油污染度采用的定期离线检测法,不能及时发现液压污染度是否超标,从而可能导致矿用自卸车故障率较高,针对这一问题,基于光阻法原理,笔者运用PIC单片机和光电传感器,设计了一种矿用自卸车车载式液压油颗粒计数器,在实验室完成了车载式液压油颗粒计数器核心部分的设计与试验;试验结果表明,该颗粒计数器具有较高的准确性和稳定性。
The regular off-line detection method is used in the detection of hydraulic oil contamination of mining dump truck at present, which results in the failure to find whether the contamination exceeds the range in time, thus high failure ratio of the mining dump truck may occur. In view of this problem, a kind of vehicle- mounted hydraulic oil particle counter for the mining dump truck was designed based on light blockage method and by applying PIC MCU and photoelectric sensor. In addition, the design and the test of the core part of the vehicle-mounted hydraulic oil particle counter completed in laboratory. The test results showed the particle counter was characterized by high accuracy and stability.
