LFY-607B Thermal Protection Performance Tester

Main purpose 
This instrument is mainly used for testing the heat insulation performance of flame-retardant protective clothing, fire-fighting suits and gloves when exposed to radiant heat sources and convective heat sources. 
Technical indicators

1. The irradiated area of the sample: 100 cm² ± 0.01 cm² 
2. Heat Source: 
(1) The radiation heat source uses a specially designed T-150 infrared tube (with a 5-bracket for the filament), and the integrated voltage regulation range is: 0 to 220V. 
(2) The radiation intensity from the convection heat source can be continuously adjusted at an angle of 45 degrees. The convection heat source uses a self-made large-diameter self-generated lamp and a high-voltage pulse igniter. 
(3) Adopt the RT18-63R rapid protection circuit; 
(4) The guard rail and sample holder are equipped with large-stroke rodless cylinders. The movement speed can be adjusted, and the response time is less than 2 seconds. 
(5) Automatic ignition by high-voltage pulse; 
(6) The air leakage protection device can automatically cut off the air path electromagnetic valve; 
3. Temperature measurement range of the calorimeter: 0°C to 85°C ± 0.1°C; The two sets of calorimeters are used according to different standards and are equipped with dedicated plug-in interfaces, allowing for quick and convenient switching. 
4. (1) Thermal flux of the radiation heat source: 10 - 50 kW/m² 
(2) Heat flux of convective heat source: 10 - 50 kW/m² 
(3) Total heat flux: Adjustable from 50 kW/m² to 100 kW/m² (in accordance with the standard requirement, it should be 83 kW/m2 ± 2 kW/m²) 
(4) Thermal source accuracy: ±2% 
(5) Methane flow rate adjustment range: 0 - 10 L/min 
(6) Air flow adjustment range: 0.6 - 6 m³/h 
5. Detection indicators: Thermal protection coefficient TPP, computer display time - temperature curve. 
6. Instrument Structure: 
(1) The ventilation cabinet and the instrument are designed in an integrated manner, making the operation convenient. An integrated stainless steel cabinet is used, with a rounded arc-shaped test chamber door that has a large opening area and is equipped with cylinder support; an exhaust hood made of fireproof and high-temperature-resistant materials is also built in. 
(2) The system is controlled by a computer. The professional industrial control computer is used to automatically control the entire testing process. The operating system is fully in Chinese, making the operation simple and convenient. Automatic data processing is available; the test results can be printed out. 
(3) The instrument is equipped with a dedicated cooling air gun for sensor components. After each test, the air gun is used to cool the sensor components, which results in rapid cooling and enhances the efficiency of conducting large-scale tests. 
(4) Motion range of the guardrail and sample holder: 450mm, response time ≤ 2 seconds 
(5) Built-in fireproof and high-temperature resistant exhaust hood: 0.35A / 220AC; 
(6) Both the guard fence and the sample holder are driven by large-stroke rodless cylinders as the main driving components. They have a large transmission stroke, adjustable movement speed, and fast response, which improves the response speed of the instrument tests and reduces measurement errors. 
(7) The sensor is sampled using a 12-bit high-speed A/D converter, which offers high sampling accuracy and fast speed. 
(8) The components of the instrument that are close to the heat source are all cooled by water. This not only ensures the service life of the components but also avoids the influence of the heat source temperature on the experimental results, thereby improving the overall testing accuracy of the instrument. 
7. Sample holder dimensions: 150×150mm and 200×200mm 
8. Instrument dimensions: 1450mm × 630mm × 1350mm 
9. Power Supply: AC 220V, 50Hz, 6kW 
10. User-provided: One methane gas cylinder and a gas supply set, as well as one air compressor.
