Problems solved by technology

This patent cannot change the shape and gap of the slit according to the needs, and the material constituting the slit is inconvenient to replace
At the same time, it mainly focuses on the contents of the liquid rather than the flow of the liquid itself, and it cannot control the initial state of the liquid, and the two sides that make up the slit also remain relatively static, so it is not suitable for related research in this field

Abstract

The invention discloses a drop seepage characteristic monitoring method and device for cross-scale movement slits. No monitoring devices are available for monitoring flowing behaviors of drops to cross millimeter-micron-nano scale slits. A horizontal positioning block and a vertical positioning block are horizontally and vertically positioned by a tested sample separately; a slit shape and gap between the tested sample and a standard glass brick are set by means of an adjusting bolt on the standard glass brick; an injector is adjusted to a preset height by means of a lifting table to obtain the initial speed of the drops into the slit; and the relative movement speed of the tested sample and the standard glass brick in the vertical direction is set by setting the movement speed of the vertical positioning block. By adding a preset liquid into an injection syringe, a feeding mechanism enables the injector to fall drops in preset volumes, and after the drops enter the slit, the seepage characteristic is photographed and recorded through a high-speed camera. The distance between the silts is precisely controlled by means of an optical detection and joggling control method. The flowing state of the drops in the relative movement silt is monitored by means of a high precision slide rail and the high-speed camera.

Description

technical field [0001] The invention belongs to the technical field of seepage characteristic monitoring, and in particular relates to a method and a device for monitoring the seepage characteristic of liquid droplets into a cross-scale moving slit. Background technique [0002] The flow behavior of liquid droplets into micro-nano slits has appeared in many fields. For example, the seepage of cutting fluid in the slit formed by the tool and chips during turning will greatly affect the quality of turning. Similarly, during the welding process, the flux is melted and applied above the connecting slit of the two connected parts. If the penetration of the molten metal between the welds is deep, it is very conducive to increasing the welding strength. This penetration behavior is consistent with Penetration of cutting fluids is similar. Microfluidic chips and microfluidic devices also have the behavior of seepage of droplets to the slit area, and the flow rate and flow rate are...
