SC Dust Test Chamber

Instrument Description:Low-voltage electrical appliances, electrical machinery, instruments, meters and other products, in storage, transport and process of sand and dust are often subject to environmental impact, especially in automotive electronics by the more significant the impact of sand and dust, the equipment is to use artificial sand and dust environment , to test the ability of the test product test equipment dust. The basic structure and principles of equipment and performance, in addition to meet on "Sand and dust test" of the requirements of national standards, but also provide non-laminar flow containing dust-like vertical circulation flow, the cycle can be observed with the use of the function of dust ; and its dust contains a large circular smooth speed control and the open air can stop automatic timer or continuous control, is ideal for sand and dust test equipment. Equipment to meet the national standard GB2423.37-89 "Dust test method", GB 4208-93 "protection provided by enclosures (IP code)", GB/T4942-93 "low-voltage electrical enclosure protection class", GB7001-96 "dust test "and other requirements.Technical parameters:1, the nominal diameter of metal mesh: 50μm, line spacing between the nominal 75μm; 2, flow rate: ≤ 2m / s or ≥ 2m / s; 3, continuous, periodic time setting arbitrary choice of blowing dust; 4, sand and dust concentration: 2kg/m3 4kg/m3; 5, Test Dust: Dry talc, cement, tobacco ash and other communication; 6, circular air flow: smoothly adjustable and can be run continuously in the operating point; 7, circular air flow timer: 0 to 99 hours 59 minutes set arbitrarily; 8, the vibration hit time: 0 999H adjustable.Main features:The chamber made of high quality steel plate surface spray, surface preparation, tank equipped with filters to prevent small items scattered on the high speed fan cycling damage. Hopper bottom of the tank with shock, the dust cycle in time. Chamber door with observation window. The lower part of the electrical control panel door to simulate sand and dust of talcum powder placed under the hopper chamber. The automatic use of circulating fans will be talcum powder jar stainless steel hole blown through the upper studio, prompting the formation of high-density fog test space-like, on the test items to test. If you need a shell according to the standard requirements of internal and external pressure of the first type of test, and standard exhaust systems can be shown in Table 3, Method 5 test trials. The sub-chamber control system with automatic and manual. Programmable time controller automatically imported. Test requirements can be set according to blowing dust, vibration time. Equipment with vacuum components: vacuum table, filter, flow meter, without vacuum (customer self-made), chamber by video glass door for easy observation in the test run process.
