Instrument composition | Fire test furnace, gas flow measurement system, temperature
measurement system and pressure measurement and control system. |
Fire 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 is used to form the furnace wall with
refractory brick in the middle of the steel structure frame. The
inner side of the furnace wall is made of high temperature
resistant heat insulation material with a density greater than
1000kg/M3. The outer side is wrapped with color steel, the
thickness of the furnace lining material is 65mm, and the test
temperature in the furnace is up to 1250℃. The furnace is produced,
installed and tested in our factory, and disassembled into suitable
reloading according to the preset function of your company. The
parts are packaged and transported into the trailer. |
Temperature measurement system | Available |
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. |
