摘要
针对螺旋槽液体润滑非接触式机械密封(简称液膜密封)特点,根据液膜密封原理,选择液膜厚度和泵送量为被控变量,隔离液压力为操纵变量,提出基于模糊理论的机械密封控制方案。运用MATLAB软件的模糊推理系统(FIS)编辑器设计液膜密封模糊控制器,对模糊控制器的输出结果进行实验验证。结果表明,所提出控制算法是有效的,可满足对液膜密封的控制要求。
In view of the characteristics of spiral groove liquid lubrication non-contact mechanical seal, a mechanical seal control scheme based on fuzzy theory was proposed according to the principle of liquid film seal, in which the film thickness and pumpage were selected as the controlled variables, and the pressure of sealing liquid was selected as the manipulated variable.The fuzzy inference system （FIS） editor in MATLAB software was utilized to design the liquid film seal fuzzy controller.The output results of the proposed control algorithm were verified by experimental data.The proposed control algorithm is effective and can meet the control requirements for liquid film seal.
