Problems solved by technology

For some jet parameters, such as jet quality, optical detection methods cannot be obtained directly, and indirect measurement has an impact on accuracy and cycle
[0005] In summary, the existing detection methods cannot fully meet the detection needs of high-speed powder jet characteristics, and it is urgent to develop an alternative or supplementary detection method, which should have low cost, easy operation, strong versatility, and direct measurement of multiple parameters. features

Abstract

A powder jet characteristic detection device comprises a movable assembly and a connection assembly, wherein the movable assembly comprises an adsorption component and a supporting component, the adsorption component is arranged to adsorb powder in jet flow, and the supporting component is arranged to support the adsorption component; the connection assembly is used for fixing the movable assembly to a jet substrate.The invention further provides a powder jet characteristic detection method.By the adoption of the capture and measurement integrated detection method and device, high-speed powder is captured through the special adsorption component, influences on jet flow are small, powder information is saved completely, characteristic parameters can be directly read by means of a ruler embedded in the device, more comprehensive characteristic parameters are obtained easily through subsequent processing, and scientific research and engineering application of the high-speed powder jet are facilitated.

Description

technical field [0001] The invention belongs to the technical field of high-speed two-phase flow and detection instruments, and in particular relates to a detection method and device for powder jet characteristics. Background technique [0002] High-speed powder jet is composed of high-speed moving gas and solid powder particles, and is often used for surface spraying and parts processing. The characteristic parameters of high-speed powder jet are quantitative parameters used to characterize the powder jet at a certain position (usually a flat substrate), including powder injection volume, powder spatial distribution, particle size distribution, etc. The characteristic parameters of high-speed powder jet affect the quality and efficiency of spraying or processing, and the development of detection methods and devices is of great significance. [0003] At present, optical detection methods and devices are usually used, such as high-speed photography (High-speed Photography), ...
