摘要
微量润滑油雾调控及雾粒传输方式直接影响油雾状态的变化,进而影响喷射至切削区域的雾粒特性。基于内置式微量润滑雾化技术和油雾内部传输应用特点,研究了不同微量润滑雾化参数和雾粒传输方式条件下油量调控性能和调控规律,并结合传输管路油雾出口雾粒特征,揭示了油雾传输管路内径和传输行程对雾粒特性的影响规律。研究结果表明,雾化室压差在传输油雾量调控上比进气压力作用显著,需要结合压差和进气压力二者影响来考虑雾化器开启数量以对传输油雾量进行调节,在传输过程中传输管路尺寸与行程是影响油雾雾粒特性的重要因素。
MQL oil mist control and mist particle transport mode directly affected the changes of oil mist states,and then affected the spraying particle characteristics to the cutting areas.The oil quantity control performance and regulation rule under the conditions of different MQL atomization parameters and mist particle transport modes were studied based on the built-in MQL atomization technology and the application characteristics of the oil mist internal transmission.The influences of the inner diameter and transmission stroke of the oil mist transmission pipeline on the mist particle characteristics were revealed by combining with the mist particle characteristics at the oil mist outlet of transmission pipeline.The results show that the pressure difference in atomization chamber plays a more significant role in the regulation of the oil mist quantity than that of the intake pressure,and it is necessary to combine the influence of pressure difference and intake pressure to consider the regulation of the oil mist quantity by the number of atomizer opening.In the transmission processes,the size and length of the transmission pipeline are important factors affecting the oil mist particle characteristics.
