Introduction of the fault and treatment method of the sand dust test chamber

The sand and dust test chamber is a test instrument commonly used for IP protection level testing
.

Mainly by simulating the damage of the natural aeolian and sandy climate to the product, it is suitable for detecting the sealing performance of the product's shell, and is mainly used for the test
of IP5X and IP6X grades specified in the shell protection level standard.

Working principle of sand and dust test chamber: Its working principle is to blow talc into the box body through the circulation pump (fan) device, and the fan pushes a certain concentration of sand and dust to blow through the surface of the test sample at a certain flow rate, testing the ability of these test samples to resist the penetration effect of dust particles under the action of dry sand or dust-filled atmosphere, the ability to defend against the abrasive or blocking effect of grit, and the ability to
store and run.

Since the dust has certain requirements for the humidity of the test environment, the sand dust test chamber needs to be used
in a relatively dry environment.

However, any test instrument is also inevitable to have some failures, this article will be the sand and dust test chamber may be the failure of the record and treatment methods
.

The fault and treatment method of the sand and dust test chamber: 1, the operation of no vibration: check whether the vibration motor is normal
.

2, the fan does not blow dust: check whether the blower is working normally or the fan is too small, check whether the dust is dry, and whether the temperature in the box is set normally
.

3.
There is dust leakage at the box door: check whether the seal of the box door is loose, and check whether the door lock is loose
.

4.
The instrument light is not lit after booting: check whether the power supply phase sequence is reversed
.
