Product Description

Product Description

Application scope: 

The high-concentration dust generating device of the dust test wind tunnel is suitable for the study of the aerodynamic performance of aerospace vehicles, especially the performance study during the take-off and landing phases. In addition, it is also used to study the fluid dynamic performance of underwater weapons and the aerodynamic characteristics of aerospace life-saving equipment, as well as the aerodynamic performance of cars and trains. The research scope of the high-concentration dust generating device also includes the aerodynamic characteristics of wind power machinery, the stress state of single or group building structures in the wind field and their response characteristics to wind loads, as well as the wind load state and wind vibration laws of bridges. These studies are not only crucial to aerospace engineering, but also play an indispensable role in transportation, housing construction, wind energy utilization and other fields.

 

Features

1. High-concentration dust meter indication error calibration.
2. High-concentration dust meter indication repeatability calibration.
3. The wind field has good uniformity and stability.
4. The dust generator has good stability.
5. The speed-adjustable fan is used with a wide speed range.
6. The test section is equipped with an observation window for easy reading and observation of the sample status.
7. The air flow rate is measured using a Pitot tube, and the test wind speed has high accuracy.
8. The tail is equipped with explosion-proof dust removal equipment, which can directly discharge dust into the atmosphere.
9. The dust injection part adopts a multi-hole design to facilitate dust mixing and make the dust mixing more uniform.
10. The cave body is designed with stainless steel to avoid the adsorption of dust by the cave wall as much as possible.
