Multifunctional automatic rain erosion resisting tester with movable workbench

Abstract

The invention discloses a multifunctional automatic rain erosion resisting tester with a movable workbench. The tester comprises a box body, a transmission system, an automatic lifting device, the workbench, a spraying device, a water supplying device and a control device, wherein the transmission system is mounted at the bottom of the box body; the automatic lifting device is connected with the transmission system through a V-shaped belt; the workbench is connected with a main shaft of the automatic lifting device through a flat key; the spraying device is fixedly mounted at the top of the box body and is connected with the water supplying system; the water supplying system and the control device are mounted at one side of the box body; the spraying device is used for simulating the influence to a materials under various rainfall environments when a test specimen is in high-speed running; the high-speed running of the workbench is realized through the transmission system; and the height of the workbench can be adjusted through the automatic lifting device. The tester disclosed by the invention is used for overcoming the defects of the existing tester that the rotating speed is low, the testing function is single and the workbench cannot be adjusted, and has the obvious advantages of being simple to operate, accurate in measurement, high in reliability, safe, stable, convenient to maintain and the like.

Description

technical field [0001] The invention relates to a multifunctional automatic rain erosion resistance tester with a movable workbench, in particular to a test device which can truly simulate the impact of rainwater on materials or equipment in terms of erosion, impact and corrosion under various rainfall environments. Background technique [0002] The multifunctional automatic rain erosion resistance testing machine with movable workbench is a new equipment specially developed for testing the rain impact resistance and corrosion resistance performance of materials in the rain and spray environment. The main function of the device is to measure the anti-destructive strength and corrosion resistance of the material under the impact of rainwater during rainfall, which can effectively judge whether the material is qualified or not, and conduct performance strengthening tests after the material is qualified. [0003] The existing rain erosion resistance testing machine has a low sp...

AI Technical Summary

Problems solved by technology

[0003] The existing rain erosion resistance testing machine has a low speed and a maximum speed of 200r / min. It can only simulate the rain environment that electronic products and their components may receive during transportation and use, and cannot simulate the impact of rain on the material when the test piece is running at high speed. The existing rain erosion resistance testing machine can simulate one of the environments of rain or spray rain, but the working performance is single, and it cannot simulate a variety of rainfall environments, and the nozzle or nozzle type is used, which can only be achieved by changing the diameter of the nozzle. Changing the size of the raindrops cannot achieve continuous adjustment of the size of the raindrops. At the same time, the sprayed rainwater can only be evenly distributed according to certain rules, and it is impossible to realize the uniform distribution of the randomness of the raindrops in the actual rainfall environment; the existing rain erosion resistance test machine works The table can only be rotated, but cannot be adjusted up and down. The distance between the workbench and the spraying device is fixed, and the internal activity space of the box is limited. The workbench can only install test pieces with small dimensions, and large-size test pieces with complex shapes cannot be installed. into the box, making it impossible to conduct sufficient rain and spray tests
