Application:
The sand and dust test chamber is simulates the destructive nature of the natural sand-sand climate and is suitable for testing the shell sealing performance of the product. It is mainly used for the tests of IP5X and IP6X specified in the enclosure protection level standard.

The test chamber is use for low-voltage electrical appliances, motors, instruments, meters, lamps, household appliances and other products, in the storage, transportation and use of the process will often be affected by dust and dust environment.Especially cars, electrical appliances affected by sand dust is more significant. This equipment is the use of artificial simulation of dust and dust environment, to test the test dust on the test equipment, test specimens in this environment, the sealing and corrosion resistance

Features of sand dust testing machine
1. Using a powerful dust spray device, the user can independently control the conditions of floating dust 1, floating dust 2, and floating dust 3 on the panel.
2. The use of vibration equipment can make the dust concentration the same every time.
3. The precise dust concentration collector can reduce the miscalculation of the concentration due to improper operation.              
 
Working principle of chamber:
Centrifugal fan is the main source of dust movement, the high-speed operation of the fan so that dust into the fan due to the centrifugal force of the role of fan blades into the dust pipe dust. The wind speed of the pipeline is usually more than 7.5m / s (too low wind speed will make the dust precipitate in the pipeline will cause the test tube can not work). The dust line was sprayed from above into the test chamber and passed through the sample at a rate of> 2 m / s. Sand and dust chamber As the lower part of the working box for the funnel, it can precipitate down the dust into the lower part of the 72 × 50um filter. Through the vibrating motor vibration, less than the diameter of the filter hole in the dust and centrifugal fan sucked so back and forth. 

Technical parameter

Electronic and Control systems:
1. The main controller LCD touch screen, can do programmable test
2. PLC complex man-machine interface control, contrived moving time, rest time and power-on time setting.
3. multiple sets of test procedures can be planned in the interface, and each group can be arbitrarily set the desired action, easy to operate.
4. If a fault occurs in the operation of various signals are written records will be displayed to facilitate maintenance.
5. Touch the setting, digital direct display, all the conditions fully automatic locking by a microcomputer.
6. Hight quality electronic temperature and humidity sensor, not need to cleanup.
