Dustproof test method for dustproof level test equipment

Dustproof Test Chamber also known as Dustproof Level Test Equipment is suitable for welders, electronic equipment, electrical products, auto lights, motorcycles, chemical plants and other parts and components Anti-fouling test of the material, and then check the shell sealing performance of the goods GB4208-93 shell protection level IP5X/IP6X anti-fouling test. pxjTextile Testing Instruments, Testing Equipment Manufacturer

The key to the dustproof test chamber is to simulate the damage of wind and sand temperature to hardware locks, auto parts, hydraulic seals and power engineering surface lamps. pxjTextile Testing Instruments, Testing Equipment Manufacturer
Dust-proof test chamber Use a powerful centrifugal fan to increase the sand and dust with a necessary concentration value, blow out the surface of the test product with the necessary water flow, and then comment on the effect of preventing the penetration of floating dust particles under the effect of being exposed to dry sand or filled with dust air Effect Ability. Ability to prevent gravel corrosion or clogging, as well as storage and handling capabilities. pxjTextile Testing Instruments, Testing Equipment Manufacturer

Structural advantages of dust-proof test chamber:pxjTextile Testing Instruments, Testing Equipment Manufacturer
1. Dust-proof test box is produced and processed with high-quality raw materials. The surface of the box and the door wall are made of high-quality thick steel plates. The surface electrostatic induction color electrostatic spraying solution has harmonious color matching, curved design scheme, and wire frame Naturally smooth. pxjTextile Testing Instruments, Testing Equipment Manufacturer
2.Dust-proof test chamberThere is a detachable dust replacement device at the bottom, which can easily replace the applied dust 100%. pxjTextile Testing Instruments, Testing Equipment Manufacturer
3. The raw material of the inner tank is made of high-quality stainless steel plate. The design scheme is a closed indoor space, and the sealing test of the shell can be carried out according to the test piece. The indoor test frame and its accessories are made of stainless steel, and the design scheme is effective. pxjTextile Testing Instruments, Testing Equipment Manufacturer
4. There is a large window on the tailgate and lighting equipment in the box. During the experiment, the experimental situation in the room can be clearly checked and the test piece can be seen clearly. The tailgate adopts two layers of rubber sealing strips, which are tightly sealed and convenient for power switch. In the box there is a very designed device to place the test product. pxjTextile Testing Instruments, Testing Equipment Manufacturer
5. Install a unique sand and dust test chamber to ensure that the smoke does not stick to the inner wall of the chamber and solidify. The working time of the equipment is adjustable and can be automatically replaced. pxjTextile Testing Instruments, Testing Equipment Manufacturer
6. Under the premise of meeting the national industry standards, the sand and dust test chamber has stable characteristics at all levels, which is basically more applicable and more conducive to operation. The sand and dust test chamber is easy to install and use, and most of them do not require daily maintenance. pxjTextile Testing Instruments, Testing Equipment Manufacturer
7. Dust-proof test chamber is equipped with a vertical dust circulation system to rotate, and talcum powder is used as smoke. The smoke is blown into the air supply mode channel through the centrifugal fan at the bottom of the tube, and then diffused evenly through the air outlet guide plate at the upper end of the device. Smoke can be evenly floated in the test chamber by circulating air flow. According to the volume of the test chamber per cubic meter, the amount of talcum powder used is 2kg, and the application frequency shall not exceed 20 times. Stainless steel plate centrifugal impeller drives smoke and dust. Air vent deflector. pxjTextile Testing Instruments, Testing Equipment Manufacturer
8. A laboratory that can conduct sand and dust tests at this stage. There are natural environment reliability and electromagnetic compatibility test management centers, aerospace natural environment reliability tests and testing institutions, etc. pxjTextile Testing Instruments, Testing Equipment Manufacturer

1. The protection level is IP5X. In normal use, the shell of type A specimens whose internal air pressure is lower than the surrounding atmospheric pressure should be provided with an air extraction hole close to easily replaceable parts, and a hose should be used to connect the air extraction hole on the specimen to the vacuum. Connect the system's exhaust ports. pxjTextile Testing Instruments, Testing Equipment Manufacturer
2. The protection level is IP5X. If the product standard clearly stipulates that the product is a B-type specimen whose internal air pressure is lower than the surrounding atmospheric pressure during normal use, the product under inspection will not be evacuated during the IP5X test. If the product standard If there is no clear regulation, the inspected products are regarded as Class A enclosures, and vacuum pumping is required when performing IP5X tests. Place the sample according to the required position specified in the sample technical conditions. pxjTextile Testing Instruments, Testing Equipment Manufacturer
3. For samples with a protection level of IP6X, whether it is a type A sample or a type B sample, the casing must be vacuumized. pxjTextile Testing Instruments, Testing Equipment Manufacturer
