摘 要: | 针对静电气雾微量润滑系统的电晕电极产生的高压静电场影响润滑油雾的荷电性能,以及电晕电极的结构形式决定了电场的强度和分布的问题,对不同电晕电极数量及布置型式对空间电场强度的影响展开了分析。利用Ansoft Maxwell软件对不同结构形式电晕电极的空间电场强度进行了仿真,并建立了电晕静电气雾微量润滑油雾荷电性能测试系统,研究了不同电极结构形式对油雾荷质比的影响。研究结果表明,对比多电晕电极,单电晕电极具有结构简单、电场强度高以及高场强集中分布于润滑油锥状气雾区域的特点。电晕电极的空间电场仿真结果与油雾荷质比实验结果基本符合,单电晕电极的油雾荷质比优于多电晕电极,适用于电晕静电气雾微量润滑系统。

Abstract: | Aiming at the problem that in electrostatic spraying-minimum quantity lubrication system, the high voltage electrostatic field generated from the corona electrode affects the lubricant mist charging performance, and the electric field intensity and distribution was determined by corona electrode configuration, the influence of corona electrode number and arrangement to the spatial electric field strength was investigated. Using Ansoft Maxwell to simulate the spatial electric field strength of corona electrode in different configuration, a system of lubricant mist charging performance of the electrostatic spraying-minimum quantity lubrication was established to conduct the tests, from which the effect of different electrode configuration on charge-mass ratio. The results indicate that compared with the multi-electrode, single electrode has a simple structure, high electric field strength and the high electric field strength concentrate in the lubricant mist tapered region. The simulated results of spatial electric field is well accord with the experiment ones, the charging performance of the lubricant mist with single electrode is better than multi-electrode, which is suitable for a corona electrostatic spraying-Minimum quantity lubrication system.
