Instructions for use of sand and dust test chamber function keys

The sand and dust test chamber, also known as the dustproof test chamber, is used to test the IP dust level of the product shell under the test environment simulating the free fall of dust. It is widely used, including but not limited to the protection grade test of various products such as electronic and electrical products, LED lighting fixtures, diving field, automobiles and auto parts.

Working principle requirements:
The powder circulating pump in the sand and dust test chamber can be replaced by other methods that can suspend talc powder. Talc powder shall be filtered by metal square mesh sieve. Straight wire diameter 50 μ m. Mesh size 75 μ m。 The amount of talc powder is 2kg per cubic meter of test chamber volume, and the number of times of use shall not exceed 20.

The time of the dust blowing test chamber can be adjusted to 0-999999 minutes. There is no time limit. It is mainly operated according to the user’s test requirements for the product.

Structural characteristics of dustproof test chamber:
The outer shell of the facility is made of cold-rolled steel plate with electrostatic spray molding, and the inner liner is made of high-grade stainless steel plate. The overall appearance is beautiful and generous. A large area observation window and manual wiper device are set in the middle of the box door, which can easily see the test condition of the test piece during the test. The main controller of the facility uses intelligent digital display controller. The main controller of the facility uses intelligent digital display temperature controller. The operation method of humanized design is easy to learn and use, and the instrument operation of different function grades is compatible. The input uses a digital correction system, with built-in common thermocouple and thermal resistance nonlinear correction tables, and the measurement is stable. It has the function of position adjustment and AI artificial intelligence adjustment, and multiple alarm modes. The facility has a timing function. Stainless steel finned heating tubes are used for heating the facilities. The dust blowing cycle and vibration cycle of the whole facility can be adjusted, and the timer for the total test is equipped.

Principle explanation and precautions of dust blowing test chamber:
1. Please pay attention to placing the device in a dry environment with good ventilation conditions.
2. Check the general functions before use (you can directly enter the manual screen)
3. Remember to turn off the power after use.
4. It is recommended that talcum powder be used no more than 20 times, and can be recycled and cleaned through the bottom of the device.
5. Regularly clean the inside of the box to avoid internal dust scaling, which may cause air outlet blockage.
6. Level the ground as much as possible to make the equipment run more stably.

Description of some key functions of sand and dust test chamber:
1. Power switch (left): used to control the power on/off status of the whole machine.
2. Emergency stop button (right): used in case of mechanical failure, operation error and other emergency situations. Press this button, all equipment actions will be stopped; In the emergency stop state, turn the key clockwise to reset.
3. Pressure gauge: used to display the actual water pressure during the test.
4. Flow meter: display and adjust the size of IPX5/6 flow; Black knob: turn it up counterclockwise and down clockwise.
5. Touch screen: used to set test parameters of protection level and control test conditions.
6. Pressure regulating valve: regulate the pressure inside the sample and the flow rate of the extracted gas when vacuuming.
7. Temperature control meter: It is used to adjust the temperature and display the temperature when testing the product.

Machine operation steps:
1. Pour talcum powder evenly into the bottom of the box.
2. Place the test sample (lamp) in the center of the network and connect it to the dust-proof socket (note: pay attention to the safety of electricity before the sample is powered on);
3. Close the door and press the “Test Start” button to automatically start the dust test. The test stops automatically until the set time.

Pretreatment sample:
1. If the technical conditions of the sample are required, the sample shall be pretreated as required to keep the sample dry. The dustproof test is a part of the shell protection test and is usually connected with the waterproof test. After the waterproof test, the sample must be dried before being put into the dustproof chamber. If no pretreatment conditions are specified for the sample, the sample shall be placed for more than 2 hours according to GB2423.37.
A. Temperature: between 15 ℃ and 35 ℃;
B. Relative humidity: 45% – 75%;
C. Atmospheric pressure: 8kpa-106kpa

What should we know about the purchase of sand and dust test chamber?
1. Select the actual model according to the product size, material, working environment and other factors. The selection of appropriate sand and dust test chamber model can meet the requirements of product testing and ensure the accuracy and reliability of the test results.
2 Performance parameters of sand and dust test chamber procurement. Considering the accuracy of the equipment, the scope of the vacuum meter, the pumping speed, the simulation speed and other aspects, selecting and purchasing the sand and dust test chamber with stable performance, accurate data and easy operation can improve the working efficiency.
3. Quality and after-sales service of sand and dust test chamber procurement. Choosing a brand of sand and dust test chamber with quality assurance and perfect after-sales service is conducive to reducing the maintenance frequency, and at the same time, it can also get professional maintenance support in time to improve the service life of the equipment.
4 Maintenance is also considered. In the process of use, reasonable maintenance can prolong the service life and reduce the failure rate. Therefore, when selecting equipment, it is necessary to understand the maintenance conditions and precautions of the equipment, and arrange professional personnel to carry out regular maintenance and cleaning work.
