45 Degree Automatic Flammability Tester is mainly used for the determination of flame retardant properties of garment fabrics, decorative fabrics, tent fabrics and so on. It is composed of control system and combustion chamber, and the specimen is installed in the combustion chamber at an angle of 45° on the specimen frame, so that the fire nozzle is close to the specimen, and the specimen is ignited with flame for a specified time and then returned to observe the combustion of the specimen and the flame spreading speed on the specimen to evaluate the ignitability and flame spreading performance. However, here, Shanghai Qianshui reminded everyone, in order to ensure the detection effect, we must usually do a good job related to maintenance work. So, how to do the maintenance of 45 Degree Flammability Tester? Below, we will explain.
1, the combustion tester gas tank should have a pressure reducing valve, the main valve off start reliable.
2, combustion tester combustion test should be operated in the presence of two people, one is responsible for the operation of the sample test, the other is responsible for supervision, check whether the gas pipeline before the test leakage, if necessary, open the pneumatic small box to check, such as joints, gas pipe is sealed to avoid accidents, the test, the tester responsible for supervision zui close to the main valve of the gas tank, found abnormalities in time to close the main valve to find the cause, the test After the test is over, be sure to close the main valve.
3, combustion tester test chamber should be installed in the air convection but can be naturally ventilated test cabinet, the test to prevent air flow, to avoid the burner backfire. The end of the test can start the fan to remove the smoke.
4, combustion tester input power supply for AC220V ± 10%, the application of grounded three-pole socket, to ensure reliable grounding.
5, the combustion tester electric control, must be time to reach the time relay control burner back to the original position.
6, combustion tester test room should be equipped with fire extinguishing equipment. Regularly check the gas circuit.
7, should not make the fire nozzle by the impact of heavy objects or vigorous bending, so as not to damage the fire nozzle affect the test.
8, the use of heavy hammer stop switch, the hammer does not need to be suspended too high, in order to protect the stop switch.
9, pay attention to clean the burning residue in the test chamber, as well as the burning traces of the specimen clip and the inner wall.
10、The instrument is a metal product, which is prone to rust when exposed to moisture for a long time, so it should be kept dry in the testing environment and be treated with anti-rust treatment regularly.
