我们在秦川机床厂生产的QCS003B型教育实验台上,按照通常采用的加载及测试程序,对溢流阀进行启闭特性试验,结果得到三和不同类型的启闭特性曲线,如图1所示。图1 启闭特性曲线(1—开启;2—闭合)曲线(a)启闭特性曲线几乎重合; (b)启闭特性曲线交叉; (c)启闭特性曲线交换位置。
We Qinchuan Machine Tool Plant produced QCS003B educational experiment stage, according to the commonly used loading and testing procedures, the opening and closing of the relief valve characteristics of the test results obtained three and different types of opening and closing characteristic curve, as shown in Figure 1 Show. Figure 1 Opening and closing characteristic curves (1-ON; 2-OFF) Curves (a) The opening and closing characteristic curves are nearly coincident; (b) The opening and closing characteristic curves are intersected; (c) The opening and closing characteristic curves are exchanged.
