XQ-828 Mobile Drum Testing Machine 
I. Application Scope of the Mobile Drum Testing Machine：
1.The mobile phone drum tester is a specialized equipment used for conducting dust erosion tests on mobile phones (or other small electronic devices). 
2. This equipment is mainly manufactured in accordance with the IEC standard GB/T1995. 
3. The structure is well-designed and unique, and it has sufficient applicability for different types of mobile phones. 
4. The equipment operates stably with low noise and requires no maintenance. 
II. Operating Procedures for Mobile Drum Testing Machine：
1.The durability of the casing. 
2. The sensitivity performance of the internal structure. 
3. Adaptability after exposure to dust erosion. 
III. Operating Procedures for the Mobile Drum Testing Machine：
During the simulation of user usage, tests were conducted to evaluate the sensitivity of the receiver of the earpiece and the corrosion resistance of the casing, taking into account the influence of external dust. 
Manually insert the mobile phone into the drum → Close the transparent cover and the protective device → The motor drives the drum to rotate clockwise again → 
Rotate the phone counterclockwise for a certain period of time, and observe the degree of erosion caused by dirt and dust. 
IV. Advantages of the Mobile Drum Testing Machine：
1.The drum rotates at a constant speed (the speed can be set) as achieved by the motor. 
2. Rotation and the internal medium occur simultaneously. 
3. The drum structure ensures that the mobile phone rotates randomly, avoiding non-standard friction and collision movements. 
V. Parameters of the mobile drum testing machine：
1. Number of workstations: 3 complete machines can be tested at one time. 
2. Operating mode: Touch screen 
3. Actuating component: Variable-frequency speed regulation reducer motor 
4. Rotating range of the drum: 300 - 600 mm 
5. Rotation speed: Adjustable from 15 to 20 times per minute. 
6. Counter: 6 digits 
7. Voltage: 220V; Power: 500W (including the motor) 
8. Dimensions: To be determined according to customer requirements. Weight: approximately 200 kg. 
VI. Notes for the Mobile Drum Testing Machine： 
1.Before conducting the test, please make sure that the power supply is properly plugged in or connected. 
2. Before conducting the test, make sure that the product is properly installed and fixed. 
3. The mechanical transmission parts must be maintained regularly. 
4. After the test is completed, it is necessary to ensure that the power supply has been turned off. 
5. It is strictly prohibited to use auxiliary corrosive liquids to clean the machine. Instead, rust preventive oil must be used. 
6. This testing machine must be used exclusively by one person. During the testing process, it is strictly prohibited to strike the machine or have anyone stand near it. 
7. The machinery must be grounded.
