1.1 It is suitable for evaluating the fire resistance of products such as fire doors installed at the openings of vertical partition members, fire shutter assemblies, fire bricks, fire glass, fire partition walls and fire windows.
2. Compliant standards:
2.1 Comply with GB/T7633-2008 "Fire resistance test—doors and shutter assemblies", ISO 3008-2007 "Fire resistance test—door and shutter assemblies" and GB/T9978.1-2008 "Fire resistance test—Elements of building construction—Part 1: General Requirements".
3. Performance characteristics:
3.1 Use 16 high-precision collection cards to collect data such as temperature, pressure, and flow of various ways. When burning, the real information of the real-time reappearance is generated by the microcomputer analysis, processing, and control. The result was directly obtained by the microcomputer. The whole machine uses high -quality devices to ensure that the system is high-quality and run at high speed. It is advanced.
3.2 Based on the lack of domestic and foreign instruments, our company often maintains technical exchanges with the field operators of fire research institutes and many companies. After nearly 10 years, it has been continuously improved and improved. The technology is very mature and customers are very recognized.
3.3 Adopt 16-bit panel card + multi-road module + microcomputer to implement the PID fully automatic control method, which is stable, repetitive and reproducible.
4. Engineering design and overall planning
4.1 Gas control part:
4.1.1 Test furnace uses liquefied petroleum gas as fuel and uses multiple bottles of pipeline installation. That is, four bottles are connected in one group, two groups in a total of eight bottles, and automated control circuits. When the pressure is lower than the set value during the test, the liquid switching valve will automatically convert to another group. This can prevent the gas from suddenly exhausted in the test and interrupt the test.
4.1.2 In order to extend the use of liquefied petroleum gas in the filling, the liquefied petroleum gas is converted from liquid gas to gaseous, so that the liquefied petroleum gas in the filling is fully burned.
4.1.3 In order to fully burn the gas after gasification, an air -combustion ratio valve is added, and the proportion of air and gas automatically can be automatically adjusted, which can achieve the best burning heating value.
4.1.4 Fuel consumption: 75 ~ 125m3/h.
4.2 Pressure release system:
4.2.1 The exhaust holes are installed on the back of the furnace wall, connected to the flue pipe behind, and discharge the flue gas in the furnace body to control the pressure in the furnace. The air exhaust in the furnace is controlled by 11KW strong fan and inverter, and its air volume is automatically controlled by the program to meet the requirements of combustion, pressure and smoke. The indoor part of the flue room uses USU310S high-temperature stainless steel pipe, and the external flue gas cooling is cooled with water steam.
4.3 Floor space:
4.3.1 Requires the floor height of more than 7.0 meters, and the total use area of the test furnace, control room, gas room, and samples: above 275 square meters.
4.3.2 Requirement environment: good ventilation and convenient operation. There are no flammable and explosive items around the surrounding environment.
