Embodiment Construction

[0008] Such as figure 1 As shown, this dust test box includes a power unit and a box body, and an impeller 2 for stirring dust is provided at the bottom of the box body 1, and the impeller 2 is driven by a wind wheel power unit 3 as a power unit, and the top of the box body 1 is provided with cover4.

[0009] Preferably, the size of the box is 0.2 m x 0.15 m x 0.25 m, so that the volume of the test box is greatly reduced.

[0010] Preferably, in order to better prevent dust from leaking, a pressure block is also provided above the cover.

[0011] Preferably, the wind wheel power device includes a pressure control adjustment unit, and the output power is adjusted by controlling the pressure.

[0012] Preferably, the test box is placed on the base, and the base is connected with the vibrating table, so that the vibration test is added at the same time as the dust test, which is more in line with the real operation of the parts.

[0013] In addition, the dust uses conventional...

Abstract

The invention discloses a dust test box with low energy consumption, a cheap price, simple operation and low use cost. The dust test box comprises a power apparatus and a box body. A bottom of the box body is provided with an impeller for stirring dust. The impeller is driven by a wind wheel power device which is taken as the power apparatus. A top of the box body is provided with a cover.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a dust test chamber. Background technique [0002] The use conditions of automobiles are very complicated, and the external parts of the car body are often exposed to dust. Many parts are prone to mechanism failure due to poor sealing of the parts during use. Dust test chambers are widely used in tests to verify the tightness of parts. Verify part sealing during the design phase, not after the full vehicle design is complete. [0003] The current dust test chambers generally have the disadvantages of high energy consumption, high price, complicated operation and high cost of use. Contents of the invention [0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a dust test chamber with low energy consumption, low price, simple operation and low use cost. [0005] The technical solution of ...
