Technical Parameter: 1.Equipment composition: Fire resistance test horizontal furnace, combustion control section, gas section and pressure reduction system, pressure release and measurement system, flue gas emission system, sample test stand, gas flow system, temperature measurement system (furnace temperature data acquisition system, test component temperature acquisition system), exhaust valve system, and dedicated test software.Using a 16 bit high-precision data acquisition module, various data such as temperature, pressure, flow rate, etc. are collected from various channels. Real time reproduction of the true information during combustion is generated through microcomputer analysis, processing, and control, 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. 2.Furnace structure: adopts a four layer structure, with the inner layer at 1300 ℃ and
the outer layer at room temperature. From the outside to the
inside, they are: the first layer is a stainless steel shell, and
the second layer is a steel structure frame; The third layer is
built with high-temperature bricks to form the periphery; The
fourth layer is high-temperature ceramic cotton that can withstand
temperatures up to 1700 ℃. 3.Burner:Two sets of high-pressure burners with a power of 60-80kw are used,
which have air-fuel ratio control and closed-loop control formed by
temperature feedback inside the furnace. The gas valve and air
valve can be automatically adjusted to achieve the best combustion
effect. To ensure safety, the burner selection and components are
all from well-known brands. 4.Temperature measurement system: Furnace thermocouple: The furnace adopts a wire diameter of 2.0mm that meets the
requirements of 5.5.1.1 in GB/T9978.1 and GB/T 16839.1 Four K-type
nickel chromium nickel silicon thermocouples, with heat-resistant
stainless steel sleeves on the outer cover, heat-resistant
materials filled in the middle, and stainless steel tube sleeves
made of rigid material Jade tube sheath, with a length of no less
than 25mm extending from the hot end of the sheath, and a
temperature resistance of 1250 ℃ or above. Back fire surface temperature measurement:There are 8 thermocouples on the back of the sample, of which 4 are
copper plate thermocouples (welded with 0.5mm wire diameter
thermocouples on the thick side)On a round copper sheet with a
diameter of 12mm and a diameter of 0.2mm, it meets the requirements
of the K-type nickel chromium nickel silicon thermocouple specified
in the standard GB/T 16839.1,Each copper sheet is equipped with a
30 * 30 * 2 (± 0.5) mm asbestos insulation pad with a density of
900kg/m3 ± 100 kg/m3.The thermal coefficient is 0.117-0.143W/(m.k),
which meets the requirements of 5.5.1.2 in GB/T9978.1. In addition,
the outer diameter of the other 4 positions is 1mm.High precision
K-type thermocouple, which can be buried on the back of the sample
for insulation efficiency testing; Mobile test temperature: meets the requirements of GB/T9978.1-2008; One handheld infrared
measuring instrument is used to measure the surface temperature of
each point on the backfire surface. Furnace temperature collection: K-type armored thermocouple is selected. High temperature
resistance above 1250 ℃; The furnace temperature data acquisition
system has real-time curve and historical curve storage functions,
as well as thermocouple open circuit and short circuit alarm
functions. Environmental temperature measurement: The equipment is equipped with a stainless steel armored
thermocouple with an outer diameter of 3MM for testing.Verify the
ambient temperature and comply with the K-type nickel chromium
nickel silicon thermocouple specified in GB/T 16839.1. 5. Pressure measurement system: Furnace pressure measurement: measurement range 0-100Pa; We use a French imported differential
pressure gauge, which is a T-shaped measuring probe with a
measurement accuracy of ± 0.5Pa. Equipped with overpressure
protection function, when the furnace pressure exceeds 100Pa,
execute program overpressure protection, stop gas supply, and
terminate the test; Compliant with GB/T9978.1-2008 standard; The pressure inside the furnace is recorded every 1 minute, and the accuracy of the recording
equipment is 1 second. The data collection rate is 3 times per
second. Furnace pressure control and data acquisition, ensuring
real-time control of furnace pressure in accordance with the
requirements of various standards in Chapter 2 and the smoke
exhaust system control circuit. T-shaped measuring probe: Using SUS310S high-temperature resistant stainless steel tube, it
passes through the furnace wall from inside the furnace to outside
the furnace, and the pressure inside and outside the furnace is
maintained at the same level. Pressure transmitter: French Kaimao high-precision pressure sensor. Within 5 minutes of
the start of the experiment, it is 15Pa ± 5Pa, and after 10
minutes, it is 17Pa ± 3Pa. 6. Pressure relief system: 6.1 There are smoke exhaust holes installed on the rear side of
the furnace wall, connected to the smoke exhaust pipe, to control
the pressure inside the furnace by discharging the smoke inside the
furnace. The air supply and exhaust inside the furnace are
controlled by a 0.3kw powerful fan and a frequency converter, and
the air volume is automatically controlled by a computer program to
meet the requirements of combustion, pressure, and smoke exhaust;
6.2 Pressure release pipeline: The section inside the furnace is made of high-temperature
resistant SUS310S stainless steel pipes with a diameter of 300mm,
capable of withstanding temperatures up to 1300 ℃. Use welded pipes
with a wall thickness of 5mm outside the furnace; 6.3 Pressure release power: AC220, 0.3kw high temperature resistant high-pressure fan; 6.4
Furnace pressure control and data acquisition, the furnace pressure
can ensure real-time control by forming a control loop with the
smoke exhaust system according to the requirements of the above
standards. Packing & Delivery To better ensure the safety of your goods, professional,
environmentally friendly, convenient and efficient packaging
services will be provided. Selection of Packaging Materials: Selection of Packaging Materials 1. Use sturdy and durable
packaging boxes to prevent equipment damage caused by collision or compression during transportation. 2. The interior is filled with shockproof materials, such as foam, air cushion or pearl cotton, to ensure that the equipment will not shake in the packaging box. 3. For fragile or sensitive components (such as electrodes, display screens, etc.), package and secure them separately to avoid damage during transportation. Mode of Transport: 1. Prioritize choosing professional logistics and transportation companies to ensure safety and reliability during transportation. 2. For long-distance transportation, land or sea transportation should be used to avoid the potential impact of air pressure changes on equipment during air transportation.
