1. Suitable for conducting fire resistance tests under specific fire temperature rise curve conditions and/Or building components or building accessories that require additional testing during the fire resistance test process. Unless there is a special need for any available fire temperature rise curve, the fire resistance test should still use the standard temperature time curve specified in GB/T 9978.1.

2. Vertical fire resistance test furnace for building components, vertical furnace

3. By using high-precision acquisition templates, various data such as temperature and pressure are collected from various sources. Through microcomputer analysis, processing, and control, real-time reproduction of real information during combustion is generated, and the results are directly obtained through microcomputer analysis and judgment; The whole machine adopts high-quality components to ensure the high quality, high-speed operation and progressiveness of the system. Can implement fully automatic control mode, with excellent stability, repeatability, and reproducibility;

4. High degree of automation: automatic recording of test time, automatic timing, optional manual or automatic tracking of target curve, automatic control of furnace pressure;One furnace can be used for multiple purposes, compatible with multiple standards and curves;

5. Furnace construction: Inner village contains zirconium cotton, and the combustion chamber is

6. At 1300 ℃, the outer layer temperature is at room temperature;

7. The six cylinders of the experimental framework are matched with the furnace body, and the cylinders are used to firmly seal the framework and combustion chamber, ensuring good sealing. The sample installation is flexible, simple and accurate;

Burner: equipped with automatic flame extinguishing alarm device;After the experiment, the combustion chamber will automatically cool down.

1. System operation process description

2. Before startup:Install the sample that has completed state adjustment;Natural gas: Open the manual isolation cut-off valve to check if the pressure gauge displays normally/

3. Liquefied gas: After opening the explosion-proof indoor switching valve and manual ball valve, check whether the pressure at the rear end of the primary pressure reducing valve and the pressure at the rear end of the secondary pressure reducing valve are normal；Starting conditions: high and low pressure of gas, partial pressure, self inspection of combustion supporting fan, self inspection of exhaust fan，

4. There is a problem and it cannot be started；startStage:gas

5. Butterfly valve and exhaust butterfly valve reach the set position before the experiment at the same time

6. Activate the main fuel valve control system and start the igniter to discharge high voltage for ignition; After ignition, automatically adjust the temperature and pressure inside the furnaceSafety interlock: If the equipment stalls midway, the fan fails, the gas pressure fails, or the fan pressure fails, the system will alarm and prompt to determine whether to end the experiment or reignite.Safety protection: After the experiment is completed, the system will blow the furnace to prevent residual combustible gases from exploding and cool down the furnace，Wait until the temperature drops to
