介绍新型旋转水流式空蚀试验装置的原理及使用该装置的试验成果。该装置能在不需要提高驱动功率的情况下,试验较大体积的试件(如混凝土等)的空蚀强度,因而克服了常用的试验装置,如:超声波磁致伸缩仪,文丘利试验管及转盘空化器等在试验较大试件方面的困难,并用混凝土和金属材料的空蚀试验成果,证明了本装置具有良好的性能。 The principle of the new rotary flow cavitation erosion test device and the test results using the device are introduced. The device can test the cavitation strength of larger volume specimens (such as concrete, etc.) without increasing the driving power, thus overcoming the commonly used testing devices such as ultrasonic magnetostrictive devices, venturi test tubes And turntable cavitator and other large specimens in the test of the difficulties, and with concrete and metal cavitation test results, the device has proved to have good performance.
