Congratulations on the timely delivery of our wire and cable testing instrument K-18380 single vertical combustion testing machine to our Shaanxi customer
Operating Procedures for Single Vertical Combustion Testing Machine
1. Connect the air pipe to the air inlet of the box and check the air duct interface to prevent air leakage
2. Connect the gas pipe to the gas inlet of the box, check the air duct interface to prevent air leakage
3. Turn on the power switch
4. Experimental parameter settings: The combustion time and experimental angle adjustment settings are set according to the experimental standards.
5. Fix the test sample on the sample holder.
6. Open the main valve of the gas cylinder to connect the gas source, press the "start" button, adjust the gas pressure adjustment knob (if the pressure gauge is turned up at this time, adjust the flow meter knob to open a little, and then adjust the pressure adjustment knob) and the flow meter knob to the standard specified value (gas pressure is usually 0.06-0.1Mpa, gas flow rate: 650 ± 30mL/min, or 0.65L ± 0.03L/min). Press the 'Start' button to ignite.
7. Turn on the air compressor, insert the air pipe into the air quick plug, adjust the air pressure adjustment knob and flow meter knob to the standard specified value.
(Air pressure: 0.1Mpa, air flow rate: 10 ± 0.5L/min, actual pressure and flow adjustment subject to flame height: blue flame core height 50-60mm, outer flame height 170-190mm)
Adjust the flame height according to the test requirements: fine tune the air and gas flow rates separately to make the flame meet the test requirements. Without replacing the gas source or pipeline, it is generally not necessary to turn off the pressure gauge and flow meter after adjusting the air and gas pressure and flow rate. The next test can be directly ignited.
After the set time combustion test is completed, the "start" button will pop up, disconnect the gas, and the flame will automatically extinguish.
8. Adjust the blowtorch to a position at a 45 degree angle to the horizontal direction, facing the test sample directly.
The length of the cable sample is 600 ± 25mm.
9. Press the "start" button, the blowtorch will ignite, and the timer will start counting.
When repeating the experiment, the above steps can be repeated.
11. After the experiment is completed, close the main valve and reset all components.
