Common Malfunctions and Maintenance Guidelines for Blasting Strength Testers

In daily quality inspection work, the durability testing machine is a key equipment for testing the performance of packaging materials, and its stability directly affects the accuracy of test results. However, under long-term high-frequency use, equipment malfunctions are inevitable. This article will provide a detailed overview of common types of faults and corresponding maintenance methods, helping technicians quickly locate the problem and restore normal equipment operation

1. The cardboard cannot be broken
   Reason: The oil cup is not tightened or there is air inside the oil cylinder.
   The solution is to loosen the nut of the oil cup and press the rubber film multiple times with your fingers to release air from the oil cup. Tighten the oil cup nut after the rubber film is restored.
2. The cardboard cannot be broken and there is oil leakage on the lower pressure plate
   Reason: The rubber film has been damaged and broken.
   The solution is to replace the rubber film
3. Incomplete cardboard rupture or failure to return immediately after cardboard rupture, resulting in an instant occurrence of oversized values or rubber film rupture in the system
   Reason: Incorrect setting of 'breakpoint ratio'
   The solution is to modify the 'breakpoint ratio'
   Note: The breakpoint ratio value is generally set within the range of 80% -95%.
   Generally, if the cardboard test result exceeds 10Kgf/cm ², the determination ratio is set at 80% -90%;
   If the cardboard test result is below 10Kgf/cm ², the determination ratio is set at 90% -95%;
   If it is a test paper or pit paper, it needs to be stacked with 2-5 layers, and the number of layers should also be set to 2-5 layers, otherwise the peak value cannot be grasped, and the adhesive film is easy to break.

In summary, the common faults of bursting strength testers are mostly related to improper operation, component wear, or environmental factors. By following the step-by-step maintenance guidelines provided in this article, you can effectively resolve most minor malfunctions, extend the service life of the equipment, and ensure the accuracy and stability of test results. Proper daily inspection and regular maintenance are the key to reducing failure rates and improving work efficiency—simple daily checks, such as cleaning the pressure sensor and checking the tightness of connecting parts, can avoid many unnecessary faults.
