目前机床液压系统中广泛应用的压力阀有时会出现尖叫声。在出现这种现象的同时,压力也会急剧波动,其中以顺序阀和溢流阀较为严重。为了解决这个问题,我们进行了种种分析和试验研究工作,目前已经研究出一种能基本消除这种压力阀尖叫声的简单而有效的方法。 Pressure valves that are widely used in machine tool hydraulics now sometimes scream. At the same time as this phenomenon occurs, the pressure will fluctuate sharply, among which the sequence valve and the relief valve are more serious. In order to solve this problem, we conducted a variety of analytical and experimental studies. We have now developed a simple and effective method that basically eliminates this type of pressure valve squeak.
