新产品与国外样机进行性能比较,要在同一试验台、使用相同的测试方法和手段(相同条件)是非常重要的。而正确的测试方法和合理搭配仪器则往往是十分关键,正确合理与否影响数据或曲线的真实性和可靠程度。我们在新产品和西德Rexroth公司DB型10通径先导式溢流阀样机作启闭特性性能试验时,测试上进行了一些偿试和探讨,最后采用如图1所示的方法将压力和流量通过转换二次仪表放大,经函数记录仪直接绘出曲线。试验结果表明数据
New product and the performance of foreign prototype comparison, to the same test bench, using the same test methods and means (the same conditions) is very important. The correct test methods and reasonable with the instrument is often very crucial, correct and reasonable or not affect the authenticity and reliability of the data or curve. In the new product and West Germany Rexroth DB type 10-channel pilot pilot relief valve prototype performance test for opening and closing, the test carried out a number of tests and discussions, the final use of the method shown in Figure 1, the pressure and the Flow through the conversion of the second instrument to enlarge, the curve plotted directly by the function recorder. The test results show the data
