Embodiment Construction

[0023] Hereinafter, the present invention will be further explained through specific embodiments in conjunction with the drawings.

[0024] figure 1 A schematic diagram of the spray array combination in the large-scale salt spray environment simulation test system of the present invention is given. The spray array combination method of the present invention needs to reasonably combine spray units according to the size of the large-scale salt spray environment simulation test system, so as to achieve various technical indicators of the large-scale spray environment simulation test system. First, the test space needs to be divided, including theoretical analysis and simulation calculation based on the characteristics of the multi-unit fog field, and the space division method will be in matrix form. That is, based on the effective settlement range of each unit, they are arranged in a matrix form, and the relative relationship between the plane projections of each unit is positioned ...

Abstract

The invention relates to a method applying a small-sized modular spray device combination to a large-scale salt spray environment simulation space, which comprises the following steps: firstly, analyzing projected area of test effective space, taking two formulas as the basis to calculate the column number and line number of rectangular array of small-sized modular spray devices, further, and combining the requirements of preventing test effective space condensate water from dripping, wherein each column adopts the mode of symmetrical triangle layout. The invention is a building method for modular and combination of spray site of a large-scale salt spray test system, is characterized in that the invention can be suitable for the requirements of test spaces with different scales, the deposition rate uniformity of the whole site is good, the effect of preventing condensate water from dripping is good, and the ability for coping with the faults of a small number of units is strong, and is a key method for building the large-scale salt spray environment simulation test system.

Description

Technical field [0001] The invention belongs to the technical field of environmental simulation. Specifically, it relates to a method that uses a small modular spray unit as a basic component and is applied to a large space salt spray test system through combination. Background technique [0002] At present, the spraying method of the salt spray environment simulation test box in a larger space mostly adopts the side wall multi-nozzle combined spraying method. This method can still control the sedimentation rate within the index range when the test space width is small, but the uniformity is poor. When the width of the test space is expanded to more than 6m, the settlement rate index in the middle area under this method is difficult to achieve. If the pressure of the atomizing air source is increased, the initial velocity of the droplets is increased, and the coverage distance of the fog field is increased, it will cause a larger air flow in the space, which does not meet the r...
