Work principle and method of horizontal vertical combustion

Author: Date :2018-04-28 Views: order
Horizontal vertical burning test instrument is the analog electronic electrician product early fire happens to surrounding environment, to simulate technology assess fire hazard, ensure that caused when the products around the fire burning tendril Delay. The experimental equipment is suitable for the parts, parts and components of electrical appliances, such as insulation shell, switch panel, printed circuit board and insulating material. This model UL94 water.
 
Horizontal and vertical combustion experimental instrument, the design for the combustible performance test of equipment and appliance parts material, many applied to end-use performance test indexes such as flammable, burning rate, flame spread and burning .Both strength and flame retardant properties can be tested. High degree of automation, accurate test data.
Work principle and method of horizontal vertical combustion(图1)
 
Experimental operation method of horizontal vertical combustion tester:
1. Use the gas pipe to connect the burner and the control box and the gas tank of the gas tank, check the airway excuse and prevent the leakage.
2. Switch on the power switch 9, and set the casting time 1, the remaining flame time 2 and the remaining time 3 according to the requirements (the debugging can be set to a short time)
3. The sample of the clip, tilting burner at a certain Angle (0 °, 20 °, 45 °) adjust the jig 30 and make it to the sample position.
4. Minimize the modulation of gas flow regulator.
5. Open the gas cylinder valve, turn on the air supply, gas supply key 10, at the same time with lighters or matches on the ignition and adjustment, the pressure of gas pressure regulating valve is adjusted for 0.1 Mpa, adjust gas flow regulating valve 14, at the same time the back pressure of gas - U pressure to achieve the appropriate pressure gauge 26, flames of fire to standard height. The burner should be in a vertical position at ignition. (if the pre-mixed burner is used, the compressed air source is connected and the pressure is adjusted to 0.1mpa to adjust the air flow regulating valve 15 to enable the flame to meet the requirements)
