Customized programmable sand and dust testing equipment

1. Equipment Characteristics
With the rapid development of modern industrial technology, the application fields of electrical and electronic products are becoming increasingly broad, and the environmental conditions they are subjected to are becoming more and more complex and diverse. Only by reasonably stipulating the environmental conditions of the product and correctly selecting the environmental protection measures for the product can we ensure that the product is protected from damage during storage and transportation and is safe and reliable during use. Therefore, artificial simulated environment testing of electrical and electronic products is an indispensable and important link to ensure their high quality. Artificial simulated environment tests are scientific summaries of actual environmental impacts and are typical, standardized, easy to use, and easy to compare. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
According to the national standard/test method of constant air pressure sand and dust test, shell protection level (code)/rotating motor shell protection level, general safety requirements and testing of motor vehicle retroreflectors/lamps,/and a series of related shell protection A series of corresponding environmental test equipment have been developed according to the grade standards. The equipment is reasonably designed, simple to operate and easy to maintain, and all indicators are in line with national standards. This series of dustproof test equipment is used to test the shell sealing performance of products, and is mainly used for tests of the two levels specified in the shell protection level standards.

3. Test chamber structure
Selection of dust-proof test equipment Processed and formed from high-quality materials, the shell surface and door outer wall material are made of high-quality steel plates, and the surface is treated with electrostatic color spraying, making it beautiful and smooth. Coordinated color matching, arc-shaped design, smooth and natural lines.
The bladder material is made of high-quality stainless steel plates, and is designed to be a closed space during operation, where samples can be placed for shell sealing tests. The indoor sample racks and other accessories are made of stainless steel plates, with reasonable design and durability.
There is a large observation window on the door, and there is a lighting device inside the box. During the test, the conditions of the indoor test can be clearly observed, and the sample is clearly visible. The door adopts double-layer silicone sealing strip, which is tightly sealed and easy to open and close. The box is specially designed with a device for placing samples.
Equipped with vertical circulation airflow carrying dust, with talcum powder as dust. The dust is blown into the circulating air duct through the fan at the bottom of the funnel, and then evenly diffused by the air outlet air guide plate on the upper part of the equipment. With the help of the circulating air flow, the dust can be evenly suspended in the test chamber. The amount of talcum powder is calculated per cubic meter of the test chamber. Volume, use no more than once. There is a dust-replaceable device at the bottom of the stainless steel impeller that drives the dust and the air outlet air guide plate. The used dust can be easily replaced.
In order to ensure that dust does not stick to the box wall and condense, a special device is installed. The device can ensure that dust does not stick to the box wall and condense. The working time of the device is adjustable and can automatically work alternately. . . On the premise that the equipment complies with national standards and has stable performance in all aspects, it is more practical and easy to control. Moreover, the equipment is easy to install, simple to operate, and basically does not require daily maintenance.
4. Control system
The main controller of the equipment adopts programmable control, and the LCD screen adopts full Chinese display, which can display the year, month, day, time, working hours, etc. The fan, dust vibration and total test time can be controlled separately
This controller has a variety of arbitrary setting control functions as follows
. Time (stop, blow) continuous and periodic time settings can be selected at will
br/> . Vibration time and vibration stop time are automatically alternated
. The preset test time is a maximum of hours
. Power on and off
The control system is equipped with Schneider actuator components
With timing heating control
A heater is installed in the circulating air duct of the heating system to heat the dust to avoid dust condensation. The pipe-wrapped mica flake heating ring has safe and stable heat.
5. Spare parts and technical information
Provide spare parts (wearing parts) necessary to ensure the safe, stable and reliable operation of the equipment during the warranty period.
