在制定先导式阀的尺寸系列时,一般只是根据人们的使用经验和对阀在在静态工况下进行简单计算,来选择其主要结构参数。这种方法不能反映先导式溢流阀的动态特性。特别是在满载工况下使用时,可能使系统压力出现很高的峰值,引起系统振动,或者在压力低于调整值的情况下,阀提前开启。此外,在初步拟定阀的结构阶段,也不能够用计算的方法来评价其结构的优劣。因此,在设计液压传动系统时,往往只使用简明产品说明书
Pilot-sized valve in the development of the series, generally only based on people’s experience and the valve under static conditions in a simple calculation to choose the main structural parameters. This method does not reflect the dynamic characteristics of the pilot relief valve. Especially when used under full load condition, the system pressure may cause high peak, cause system vibration, or open the valve ahead of time if the pressure is lower than the adjustment value. In addition, the structural phase of the initial proposed valve can not be used to evaluate the merits of its structure. Therefore, in the design of hydraulic drive system, often only use concise product manual
