The 45 degree burning tester is mainly used for the determination of the flame retardant properties of clothing fabrics, decorative fabrics, tent fabrics, etc. It consists of a control system and a combustion chamber. The specimen is installed in the combustion chamber at an angle of 45° on the specimen frame, so that the nozzle is close to the specimen, and the specimen is ignited with the flame for a specified time and then returned, and the combustion of the specimen and the flame spreading speed on the specimen are observed to assess the ignitability and flame spreading performance of the specimen. 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 degrees burning test machine? Below, we will explain.
How to do the maintenance of 45 degrees burning tester?
First, the combustion tester gas tank should have a pressure reducing valve, the main valve off start reliable.
Second, the 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, so as to avoid accidents, the test, responsible for the supervision of the tester zui good near 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, the main valve must be closed tightly.
Third, the combustion tester test chamber should be installed in the test cabinet where the air is not convective but can be naturally ventilated to prevent the air from flowing during the test and to avoid backfire of the burner. At the end of the test, the fan can be turned on to remove the smoke.
Fourth, the input power of the combustion tester is AC220V ± 10%, the application of a three-pole socket with ground, to ensure reliable grounding.
Five, the combustion tester electric control, must be time to reach the time relay control burner back to the original position.
Six, combustion tester test room should be equipped with fire extinguishing equipment. Check the gas circuit regularly.
Seven, the fire nozzle should not be subjected to heavy impact or vigorous bending to avoid damage to the fire nozzle to affect the test.
When using a heavy hammer stop switch, the hammer should not be suspended too high to protect the stop switch.
9. Pay attention to cleaning the burning residue in the test chamber, as well as the burning traces on the specimen clamp and the inner wall.
Ten, the instrument is a metal product, moisture for a long time is easy to rust, should keep the test environment dry, and regular anti-rust treatment.
