【Scope of application】: It is designed and manufactured according to the corresponding requirements of MT386-2008 coal industry standard, and is suitable for flame retardant tests such as MT818-2009 coal mine flame retardant cables and flame retardant cable joints. 【Technical Parameters】: 1. Combustion chamber size: L1100*W525*H900mm, test chamber volume ≥0.5 m3 2. Size of the electric control box: L1500*W650*H1400mm 3. Load current: 10~5000A continuously adjustable. 4. Burning blowtorch: Flame vent diameter: ¢0.90±0.03mm, spout lamp length: 1.60±0.05mm, nozzle height from air inlet 102mm, flame tube inner diameter ¢9.5mm. Blowtorch angle: vertical 90° (the longitudinal axis is kept in the vertical plane and the vertical direction is 90°), self-air intake, internal flame 70~80mm, external flame 115~135mm, adjustable. 5. Temperature measurement system: imported K-type thermoelectric couple, with 1.0mm diameter stainless steel pipe as the jacket. The intelligent PID temperature control meter is matched with the K-type thermocouple. Its reading is 0~999°C 6. Operating System: Automatically record burning time, continuous burning time. Combustion timing: When the temperature of the specimen reaches the specified temperature of 204°C, the burning blowtorch moves to the lower surface of the specimen and starts burning. Automatically record the burning time (set according to the regulations: such as burning for 1 minute), and when the set time arrives, the blowtorch will return to its original position. Holding Fuel Timer: When the above combustion time arrives, this timer will automatically time; If the flame of the burned sample is extinguished during the specified time (e.g., stop the fire supply for 4 minutes), the operator will press the burning stop button to stop the time, and the time will be recorded. 7. Box material: The chassis is processed and formed by CNC machine tools, and the arc shape is beautiful and elegant. High-quality SUS304 stainless material, with the characteristics of beauty, anti-rust and anti-corrosion. 8. Timer: 0~999s 9. Ignition method: high-voltage electronic ignition, convenient and stable. 10. Working voltage: two-phase AC380V 50HZ
