Modular sand and dust test device

Abstract

This invention discloses a modular sand and dust testing device, comprising an integrated skid-mounted air duct device, a sand box device, a wind speed control system, a dust control system, and a measurement system. The integrated skid-mounted air duct device includes a base, an air duct, and a sand box cover. The wind speed control system includes two variable frequency fans, a first wind speed sensor, a frequency converter, a PLC, and a host computer. The dust control system includes an electro-proportional valve, a vacuum generator, and a first dust concentration sensor. The measurement system includes a movable measuring fixture, a second wind speed sensor, and a second dust concentration sensor. This invention can reproduce the boundary conditions of large equipment in sand and dust environments, construct a wind-dust co-loading environment, simulate the actual service status of equipment in harsh sand and dust scenarios such as deserts and arid regions, and accurately measure the sealing performance and structural response characteristics of large-scale equipment at the whole-machine level under dynamic sand and dust invasion, providing a reliable basis for the environmental adaptability design and reliability assessment of equipment.
