The application of ultrasound in cavitation treatment

Summary: In terms of anti-wear（wear-resistant）In the research process of materials, it is necessary to evaluate the wear resistance of the materialsConduct measurements, comparisons, and evaluations. For example, research and development of lubricating oil, selection of impeller materials, and centrifugationPump design, etc. During this process, ultrasonic waves are used to conduct material cavitation testsA * effective method. The ultrasonic cavitation system is achieved through high-power ultrasonic wavesUsed for samples to simulate the cavitation phenomenon at the contact surface between samples and liquids, thereby improving the gas resistance of materialsCorrosion analysis has the characteristics of high power, low investment, easy installation, and stable experimental results. The high-power vibration ultrasonic cavitation system mainly consists of three parts. They are ultrasoundWave vibration system, constant temperature oil bath container system, and rack lifting system.

The ultrasonic vibration system is the most essential part of the entire equipment, with a complex design mainly consisting ofThe system provides high-power ultrasonic vibration to meet the standard requirements for amplitude and frequency. Constant temperature oil bath capacityThe device system mainly provides a constant temperature liquid environment for the sample to ensure the accuracy of sample testing (temperature changes directly affect the cavitation rate)）The rack lifting system is used for fixing and adjusting the wholeSet up a system and designed sound insulation function.

Project Introduction

This experimental method will cause cavitation damage on the surface of the sample immersed in liquid and subjected to high-frequency vibrationInjury. The vibration of the sample in the liquid will cause the generation and rupture of bubbles, and the collapse of these bubblesCracks will cause damage and erosion to the surface of the sample(Material loss)）Although this experimental method is currently in useThe mechanism of bubble generation in dynamic systems or hydraulic presses is different, but the mechanism of material damage is basically the sameSame. Therefore, this standard provides a small-scale, relatively simple, and easily controllable test method for comparing the anti cavitation performance of different materials and studying in detail the inherent properties of a given materialStudy the anti cavitation performance and its process, or investigate the effects of different test variables on material damage under different test conditions. The experimental method specifies the diameter, amplitude, and frequency of the sampleThe standard test conditions inside, as well as the test liquid and its container. If there is a reasonable literature basis,This standard allows for deviations in certain test conditions to be applied to special purpose tests.
