Embodiment

[0050] Such as Figure 6 Before the experiment, it is necessary to prepare the dirt into a sample, fill the dirt into the sample preparation mold, heat or use other methods according to the nature of the dirt to melt and evenly adhere to the target bottom plate 610 . Then remove the side plate 1 611 and side plate 2 612 and the inner-lined aluminum foil tape by disassembling the bolts, and finally form the target bottom plate 610 with dirt attached. 610 is fixed on the dirt plate 60 with bolts.

[0051]Prepare several different dirts into samples respectively, fix one of the samples on the dirt plate 60, adjust the installation angle and starting position of the dirt plate 60, adjust the installation angle, the starting position and the starting position of the nozzle 44. Target distance, turn on the power, open the high-pressure water valve, and read the value fed back to the control box 11 by the pressure sensor 50 as the high-pressure water injection pressure value. Use t...

Abstract

The invention discloses a high pressure water jet cleaning experimental device, comprising an experimental table body module, a target distance adjustment module, a lateral movement drive module, a nozzle fixing and incident angle adjustment module, a pressure measurement module and a target fixing and adjustment module. Before an experiment, a special mold is used for preparing a sample from dirt, the sample is loaded on the target fixing and adjustment module, and then the experiment is carried out. The high-pressure water jet cleaning experimental device can digitally display the cleaning process and effects, and can intuitively display the jet action process. Relevant experimental tests can be completed by changing the type of the dirt target and jet parameters such as injection pressure, jet impact velocity, target distance, traverse speed, and an incident angle. The cleaning effect is comprehensively evaluated by measuring the cutting depth, width and mass loss of the dirt sample. The economic evaluation is carried out by recording energy consumption and water consumption, and the optimum cleaning parameters are found by observing and recording the peeling form of the dirt.

Description

technical field [0001] The invention relates to the technical field of high-pressure water jet cleaning, in particular to an experimental device for high-pressure water jet cleaning. Background technique [0002] In the existing technology, high-pressure water jets can be used to clean all kinds of dirt. Although theoretical analysis can initially reveal the mechanism of high-pressure water jets, it cannot show the impact process and effects in data. Relatively speaking, experimental research is to study jets. The most intuitive method of the action process is to study the influence of the setting of water jet working condition parameters on the impact effect through experimental analysis. For example, the material to be cleaned breaks and falls off under the impact force of high-pressure water, and the relationship between impact force and material properties, the influence of critical pressure, jet impact velocity, moving velocity and incident angle on cleaning efficiency,...
