Sand dust replacement process of sand and dust test chamber

The sand and dust test chamber is used to test the protective performance of the test piece by simulating a windy sand environment. To simulate the sand and dust environment, the equipment needs to use corresponding sand and dust tests. Currently, the commonly used sand and dust is talc powder. In order to make the test results more accurate, it is necessary to regularly replace the sand and dust.

What are the steps for replacing the sand and dust?
Because the sand and dust test chamber has requirements for the particle size of sand and dust, it is necessary to screen out sand and dust that meets the requirements using a sieve to ensure that the sand and dust are in a dry state, so that the sand and dust can be applied in relevant tests.

The process of replacing the test sand and dust: When the equipment is closed, open the door on the left side of the test equipment, and the staff will see a funnel with a flange at the bottom. Unscrew the nut on the top of the flange through a spanner wrench, and then remove the flange, Take out the test sand and dust used in the previous test, put the new test sand and dust into the screen inside the sand and dust, shake the talc powder into the funnel through manual vibration. During the test, the talc powder will enter the test equipment through the action of wind, and then conduct the test. At the end of the test, it is necessary to wait until the dust settles before opening the door.

What does regular maintenance of sand and dust testing machines include?
1. During testing, each test object must be firmly placed.
2. When the machine is not working for a long time, please regularly start the machine once a month to once a month, and start the test run once to avoid long-term storage.
3. The internal chamber should be regularly inspected and cleaned by the user to avoid falling debris entering the fan and causing blockage.
4. Pay attention to placing the device in a dry environment with good ventilation conditions and placing the ground as flat as possible to make the operation of the device more stable
5. Do not put any foreign matters in the cabinet, and keep it dry and clean
6. The machine must be well grounded during operation.

What are the precautions for dust proof test chamber?
1. When using a dust proof tester, it is necessary to check in advance whether the power and water connections are normal
2. After use, it is necessary to clean the chamber and remember to turn off the power supply.
3. It is recommended that talc powder be used no more than 20 times and can be recycled and cleaned through the bottom of the device.
4. Regularly clean the inside of the chamber to avoid dust scaling and clogging the air outlet.
5. Place the ground as flat as possible to make the equipment operate more stably.
6. It is also important to note that before using dust, it must be filtered before use.
