GB5455 Textile Vertical Combustion Tester Daily Maintenance and Care Techniques

To extend the service life of GB5455 textile vertical combustion tester, ensure its long-term stable operation and accuracy of test results, it is necessary to do a good job in daily maintenance and upkeep. The specific techniques are as follows:

1. Daily maintenance content

After the experiment is completed, promptly clean the sample residue, ash, and drips inside the combustion chamber, wipe the inner wall of the combustion chamber and the sample holder with a clean soft cloth to avoid the accumulation of combustion products that may affect equipment performance.

Check if there is any leakage at the connection of the gas pipeline. Apply soapy water to the interface and observe if any bubbles are generated. If a leak is found, immediately turn off the gas source and replace the seal.

Turn off the power and gas main valve of the equipment, keep the surface of the equipment clean and dry, and prevent dust and water vapor from entering the interior of the equipment.

2. Weekly maintenance content

Clean the nozzle of the igniter, use specialized tools to remove impurities and carbon deposits inside the nozzle, and prevent nozzle blockage from causing abnormal flame shape.

Check the accuracy of the timing system and control system, and calibrate the timing function of the equipment using standard timing tools to ensure accurate recording of ignition time and combustion time.

Check the clamping force of the sample clamp. If there is any looseness, adjust it in a timely manner to ensure that the sample is firmly installed without displacement.

3. Monthly maintenance content

Lubricate the transmission components of the equipment (such as the lifting mechanism of the sample holder), add an appropriate amount of lubricating oil, reduce component wear, and ensure smooth operation.

Check the operation status of the ventilation device's fan, clean the dust on the fan filter, and ensure that the ventilation volume meets the standard requirements.

Calibrate the flame height and use a standard gauge to measure the flame height of the igniter. If it deviates from the standard value of 40mm ± 2mm, adjust the gas flow rate and air ratio in a timely manner.

4. Annual maintenance content

Contact equipment maintenance personnel to conduct comprehensive maintenance on the electrical and gas systems of the equipment, replacing aging wires, seals, and other components.

Comprehensively calibrate the equipment, including flame height, timing accuracy, sample positioning accuracy, etc., to ensure that all indicators of the equipment meet the requirements of GB5725 standard, and keep calibration records. GB5455 Touch Screen Textile Vertical Combustion Tester (GB5725 Vertical Flame Retardant Performance Tester) The GB5455 Touch Screen Controlled Textile Vertical Combustion Tester, developed and produced by Beijing Xinsheng Zhuorui Technology Co., Ltd. and Xunyu Technology Co., Ltd., is an upgraded product based on the original equipment technology. It adopts touch screen control and has a high degree of automation in testing. In addition to the automation functions that rely on various buttons and tools, the touch screen control model can store past test data and retrieve it during testing. This device is suitable for various fabrics and their products such as safety nets, protective equipment, and seat belts, and is ultimately applicable to the test method for the combustion performance of vertical textile bottom edges when ignited as specified in the GB5455-2014 standard.

Design standard: GB5455-2014 "Determination of vertical release damage length, smoldering and reigning time of textile combustion performance"

Applicable standard: GB 8965.1-2009; GB6529 ； GB5725； GB/T 6096； GBT13489

Check if the insulation layer of the combustion chamber is intact. If there is any damage, it should be repaired in a timely manner to prevent heat loss from affecting the testing environment.
