电液伺服阀是电液控制系统中将电信号转换成液压信号的关键元件,除了比例阀控制系统外,各种电液控制系统都采用电液伺服阀,它能将几毫安的微弱电信号转换成几十马力以上的巨大液压功率输出,驱动各种负载,进行位置控制、速度控制或施力控制,它的性能好坏对液压控制系统有着直接的影响。因此,对它的性能研究显得尤为重要,必须具有专门的测试手段。通过静态性能的测试,可以知道伺服阀的滞环大小、线
Electro-hydraulic servo valve is electro-hydraulic control system will be converted to hydraulic signals hydraulic signal of the key components, in addition to proportional valve control system, a variety of electro-hydraulic control systems are used electro-hydraulic servo valve, which can be a few milliamps of weak electricity The signal is converted into a huge hydraulic power output of more than a few dozen horsepower, driving a variety of loads, position control, speed control or force control, its performance has a direct impact on the hydraulic control system. Therefore, its performance research is particularly important, must have a special test means. Through the static performance test, you can know the servo valve hysteresis size, line
