摘要: 针对传统数字阀在当前驱动方法控制下存在动态响应慢,启闭响应时间受工作压力影响大,驱动控制方法复杂以及能耗高等问题,在设计的一种新型低功耗数字阀基础上,提出一种基于响应面法的低功耗数字阀驱动参数匹配方法,在保证低功耗的同时改善其动态响应特性。通过建立低功耗数字阀的动态响应模型,分析工作压力和驱动参数对启闭响应时间的影响;基于响应面法构建启闭响应时间预测模型,以响应时间1 ms为目标,得到启闭过程中驱动参数与工作压力之间的匹配关系;搭建低功耗数字阀试验平台,验证动态模型的准确性和驱动参数匹配方法的有效性。测试结果表明,在3~19 MPa工作压力范围内,开启和关闭响应时间最长分别为1.08 ms和1.09 ms,最短分别为1.06 ms和1.07 ms,变化率均小于2%,匹配后的驱动参数有效改善了阀的动态特性及其变压力工况下的稳定性,并且长时间工作后阀温度维持在80℃左右,低功耗效果明显。

Abstract: Aiming at the problems of highly pressure-affected opening and closing time, complex driving method, high energy consumption, and slow response of traditional digital valves under the current driving method. Based on the design of a new low-power digital valve, a low-power digital valve driving parameter matching method considered the response surface method is proposed, which improves dynamic characteristics while ensuring low power consumption. By establishing the dynamic model of the low-power digital valve, the influence of working pressure and driving parameters on the response time is analyzed. Using the response surface method, the prediction model of opening and closing response time is constructed, and the matching relationship between driving parameters and working pressure is obtained with the response time of 1 ms as the target. Finally, a low-power digital valve test platform is built to verify the accuracy of the dynamic model and the effectiveness of the driving parameter matching method. The test results show that the maximum response time of opening and closing is 1.08 ms and 1.09 ms, and the shortest response time is 1.06 ms and 1.07 ms, the rate of change is all less than 2%, within the range of 3-19 MPa working pressure. The matching drive parameters effectively improve the dynamic characteristics of the valve and its stability under variable pressure conditions, and the valve temperature is maintained at about 80 ℃ after a long time. The low power consumption effect is obvious.
