Interior tank of test box manufactured by high quality and anti corrode stainless steel

Formed by 6 groups oppositely independent system

Air flow speed in frequency conversion control cabinet

Door frame double layers sealed, avoid sand dust leakage

Big size observe window used to observe samples

l Air venting port configured dust filter device

Vacuuming system of tested samples

Multiply safety protection

15 colorful touch screen with menu interface

Test data curve indication

USB joggle, able to automatic record data through U-disk

Ethernet joggle, able to remote monitor and control



System design and instruction


Use air blowing machine to realize that talcum powder circling in the box

The air blowing machine controlled by the frequency transformer, able to realize different air speed through set different frequency

The powder dust which enter into air blowing machine all have passed through filter grid in advance, use vibrator vibrate the powder dust which disperse on box wall into filter grid

Place into suitable powder dust volume according to test requirements, not exceed 4kg

The equipment configured sample vacuuming negative pressure system, connect the sample and vacuuming negative pressure joggle in box when need use then okay

Vacuuming negative system formed with vacuum pump, powder dust filter, pressure difference sensor, air flow meter and flow adjustment valve

Achieve the required flow through adjust the flow adjustment valve after calculated the air bleed flow according to test requirements

Box wall stick heating plate, achieved the purpose that reduce the humidity in box through heating to rise temperature in box

Installed the temperature & humidity integrated sensor in box to collect the temperature in box and the relative humidity
