Leather dynamic waterproof testing machineIt is a professional instrument used to test the waterproof performance of materials such as leather, synthetic leather, and fabrics under dynamic bending conditions. Its core function is to simulate the bending action and water penetration environment of materials in actual use, accurately determine the water penetration index of materials, and provide data support for the research and improvement of shoe upper materials and waterproof processing technology. Its core technical parameters include 4-station synchronous testing, a bending frequency of 50-90 revolutions per minute, an LCD counter, and an automatic penetration detection system. The equipment mainly consists of a power transmission system, a sample clamping mechanism, and a detection system. The power transmission system achieves precise stroke control through a straight groove adjustment structure. The sample clamping mechanism is equipped with movable and fixed fixtures. The detection system adopts a contact design between copper wire rings and conductive steel bars. When water penetrates and causes the circuit to conduct, the counting stop function is automatically triggered.
Leather dynamic waterproof testing machineCommon issues that may arise during use include power supply, display screen, sensors, pressure system, mechanical components, sample placement, and operating procedures. The following are specific problems and solutions:
1. Power issue
Problem manifestation: The device cannot start or suddenly loses power during operation.
resolvent:
Check if the power cord is connected properly and confirm if the power socket is powered on.
If the device is powered by batteries, check if the battery is fully charged and replace it if necessary.
Check the power plug and socket to ensure a secure power connection.
Check if the device fuse is blown and replace it if necessary.
2. Display screen issue
Problem manifestation: The display screen has no display, abnormal display, or inaccurate display content.
resolvent:
Check if the display screen connection cable is loose or damaged, reconnect or replace the connection cable.
Refer to the equipment manual to confirm if the display screen parameters are set correctly, and make adjustments if necessary.
If the display screen is damaged due to impact or compression, it needs to be replaced.
Try restarting the device or reinstalling the software to see if it can solve the problem.
3. Sensor issues
Problem manifestation: inaccurate or no sensor readings.
resolvent:
Check if the sensor is aging or damaged, and replace it if necessary.
Check if the sensor connection wire is loose or damaged, reconnect or replace the connection wire.
Regularly calibrate the equipment to ensure the accuracy of testing.
4. Pressure system issues
Problem manifestation: Abnormal equipment pressure, such as high or low pressure.
resolvent:
Check if there is any malfunction in the pressure regulation system inside the waterproof testing machine, and adjust or replace relevant components in a timely manner if there is any abnormality.
Confirm whether the sample can withstand the preset pressure to avoid abnormal pressure caused by sample problems.
5. Mechanical component issues
Problem manifestation: Mechanical components are stuck, worn, or damaged.
resolvent:
Regularly clean and maintain mechanical components, such as cleaning fixtures, inspecting seals, etc.
Check whether the mechanical components are worn or damaged, and replace them promptly if necessary.
For key components such as fixtures, ensure that they are tightly connected to the sample and have good sealing performance.
6. Sample placement issue
Problem manifestation: Incorrect placement of test samples can lead to inaccurate test results or trigger alarms.
resolvent:
Ensure that the test sample is placed flat on the test stand in the specified direction.
Carefully check the placement of the sample before testing to avoid problems caused by improper placement.
7. Operational process issues
Problem manifestation: Equipment alarm or inaccurate test results due to improper operation.
resolvent:
Carefully read the equipment manual to understand the operation method and precautions of the waterproof testing machine.
Ensure that the correct test parameters have been set and the appropriate test mode has been selected before operation.
Provide training or guidance to operators to improve their operational skills and experience.
