Zhenghanginstrument-Resistancesand dustagingCharacteristics of the test chamber:

◆、Suitable for conducting dust and dust resistance tests on various automotive components, including headlights, instruments, electrical dust covers, steering systems, door locks, etc.

Zhenghanginstrument-Resistancesand dustagingTechnical parameters of the test chamber：

◆、Metal mesh standard nominal wire diameter:50μmThe nominal spacing between lines is75μm

◆、Airflow velocity: ≤2m/sOr ≥2m/s

◆、Continuous and periodic dust blowing with arbitrary time settings

◆、Dust concentration:2kg/m3～4kg/m3

◆、Experimental dust: dry talcum powder, Portland cement, smoke ash, etc

◆、Vibration time:0～999Hadjustable

Zhenghanginstrument-Resistancesand dustagingTest box structure：

◆、Box shell material: High quality steel plate with spray coating treatment

◆、Inner liner material:SUSStainless steel light plate

◆、Visible glass door for easy observation of the condition of the tested sample inside the test chamber

◆、The bottom of the box adopts high-quality fixable designPUActivity Wheel

◆、There is a dust replacement device at the bottom

Zhenghanginstrument-Resistancesand dustagingDust preheating system for test chamber：

◆、The mica sheet heating ring wrapped in a pipeline ensures safe and stable heating, with timed heating control.

Zhenghanginstrument-Resistancesand dustagingTest box circuit control system：

◆、The use of imported programmable controllers effectively ensures that the test runs according to standards, equipped with vacuum actuators, Schneider actuators, and automatic alternation of dust blowing fan time and vibration and stop vibration time.

◆、Vacuum pressure indication of test chamber

◆、The programmable controller has four output points to simultaneously complete program execution at four different times. Each output point has two time periods for control (i.e. start time and stop time), which can individually or collectively control the blowing fan, dust vibration, and total test time.

ResistancedustTest box protection system：

◆、Non fuse protection switch, over temperature, overload, leakage, fully sheathed terminal block, with automatic shutdown protection, etc
