Technical parameters
Fire Resistance Test Instrument composition: fire test furnace, temperature measurement gas flow measurement system and pressure measurement and control system.
Fire Resistance Test furnace: It is a vertical test furnace with an inner size of 2.5M (length) x 2.5M (deep) x 1.25M (height).
Furnace structure: steel structure frame wall with refractory brick steel structure frame. The inner side in the middle of the of high temperature is used to form the furnace resistant heat insulation the furnace wall is made of material with a 1000kg/M3. The outer steel, lining density greater than material is 65mm, and the test the thickness side is wrapped with color of the furnace temperature in the furnace is up to 1250℃. The furnace tested in our reloading according to factory, suitable the preset function installed and disassembled is produced and into of your company. The parts are packaged and transported into the trailer.
Temperature measurement system
Thermocouple in the furnace: K-type nickel-chromium nickel-silicon thermocouple with wire diameter of 2.0MM according to GB/T16839.1, heat-resistant stainless steel casing with outer casing, heat-resistant material in the middle, the length of the heat end extension sleeve is not less than 25MM, a total of 5, the temperature accuracy is <±15℃.
backfire surface temperature measurement: using a diameter of 0.5MM thermocouple, fusion welding in thickness of 0.2MM, diameter of 12MM
On the round copper plate, the large nickel-chromium nickel-silicon thermocouple according to GB/T16839.1 should cover the length and width.
Both are 30MM asbestos liners with a thickness of 2.0MM. 20 in total
Average temperature measurement: 8 thermocouples, suitable for GB/T7633-2008 and GB/T17428-2009
Maximum temperature measurement: The thermocouple is a measurement of 20 double doors with a molded slab that can cover up to a maximum door width of 1200 mm.
Mobile thermocouple: using infrared thermometer measurement
Internal thermocouple: 4 thermocouples, which are suitable for measuring the internal temperature of the ventilation duct.
Ambient temperature measurement: An armored thermocouple with a diameter of 3.0 mm is used, which conforms to the large nickel-chromium nickel-silicon K-type thermocouple specified in GB/T16839.1.
Pressure measurement in the furnace: T-shaped measuring probe, measuring accuracy ± 2pa. Three pieces
loading system: using a pressure sensor to measure
Deformation measuring instrument: using electronic deformation measuring device
Slot probe: made according to GB/T9978.1 standard
Burner: There are 8 high-speed burners embedded in the furnace walls on both sides, six on each side. Provides the heat needed to heat up the furnace.
Exhaust smoke: Three exhaust holes are installed in the furnace wall on the back side of the furnace wall to connect to the flue behind, and the flue gas in the furnace body is discharged. Control pressure.
Fire hole: There are two fire holes on the back side wall of the furnace body to observe the fire surface and flame of the test piece during the test.
Loading device: It adopts a cart, which is 3.5M high and 3.0M wide, and is composed of a car body and a test piece platform. The car body is designed with four ground wheels, which can be moved on the rail. The test platform: 3.0m*3.0m square steel frame. During the test, the test piece platform with the test piece was lifted onto the vehicle body with an electric hoist, then the cart was pushed to the test position and fixed, and then the test was started.
Electrical control part: MCGS configuration software and PLC program using embedded integrated industrial computer. Including: main control interface, furnace temperature curve interface, test piece temperature interface, history record interface and parameter determination interface
Frequently Asked Questions:-
What is ISO 834?
The Standard temperature-time resistance of the fire subjected materials curve ISO 834, also known as the Cellulosic curve and the standard nominal fire curve, is used to test to a category “A” fire hazard
How does a damper work?
Dampers are plate-shaped or close to regulate the amount device which opens of air that passes and vents. Making adjustments on the damper cold or hot air into some through the duct affects the indoor temperature by pushing areas or sections of the house.
