Ventilation Ducts Refractory Test Furnace Fire Test Chamber , Red Flame Test Equipment
Scope of application:
Suitable for horizontal fireproof performance of ventilation pipe under the condition of the standard fire test method, used to detect the ventilation pipe external fire under (A) fan and internal fire (B) fan effect of fireproof performance. The test furnace can also be used for vertical ventilation ducts.
Meet the standard:
Conformity to GB/t17428-2009 "ventilation pipe fire test method" and GB/T9978.1-2008 test standard.
Composition: fire resistance test furnace, gas flow measurement system, temperature measurement system and pressure measurement and control system.
Furnace structure; The steel structure frame is adopted, and the furnace wall is used in the middle of the steel structure frame. The inner wall of the furnace is used for high temperature insulation material, and the density is greater than 1000kg/M3. Lateral with colored steel, furnace lining material thickness is 65 mm, furnace temperature test temperature as high as 1250 ℃. The furnace is produced in our factory, the lining and test are installed, according to the function of your company's presupposition, it is disassembled into the package of the parts to be packed into the trailer transportation.
Refractory test furnace: for vertical test furnace, the inner dimension of 3M (long) x4. 5M (deep) x3M (high).
Temperature measurement system:
Furnace thermocouple: furnace using meet the requirements of GB/T16839.1 wire diameter is 2.0 MM of K type thermocouple, nickel chrome - nickel silicon cover heat-resisting stainless steel casing, middle filled heat resistant material, the hot end stretched out the length of the casing not less than 25 MM, a total of 5 pieces, the accuracy of temperature < + 15 ℃.
The temperature of the back surface is measured: the diameter is 0.5mm thermocouple and the fusion welding is 0.2mm thick and the diameter is 12MM
In the round copper strip, the thermocouple of large nickel chrome-nickel silicon, which conforms to GB/T16839.1, should cover long and wide
Both of them are 30MM thick asbestos gasket. A total of 20
Average temperature measurement: the thermocouple is 8, which is suitable for GB/t7633-2008 and GB/t17428-2009
Maximum temperature measurement: the thermocouple for 20 branches can cover the maximum door fan width of 1200mm with the double door of the model.
Mobile thermocouple: measured by infrared thermometer
Internal thermocouple: the thermocouple is 4, which is suitable for the measurement of internal temperature of ventilation ducts.
Environmental temperature measurement: the diameter is 3. The armor thermocouple of 0MM is in accordance with GB/T16839. Type K thermocouple for large nickel chrome-nickel silicon.
Pressure measurement in the furnace: measuring the probe with t-shaped measurement, measuring accuracy of plus or minus 2pa. three
Loading system: using pressure sensor to measure
Deformation measuring instrument: electronic deformation measurement device
Crack detection: by GB/T9978.1 standard
Burner: there are 8 high - speed burner on both sides of the furnace wall, six on each side. Provide the heat needed to heat up the furnace.
Smoke exhaust: three smoke holes are installed in the wall of the furnace wall, connected to the rear flue, discharging the smoke from the furnace. Control stress.
View hole: two hole holes are provided in the rear side of the furnace to observe the fire surface and flame in the test.
Loading device: the trolley, 3.5m high and 3.0m wide, consists of the body and the specimen platform. The body design of four wheels can be moved on the rail, the test platform: 3.0m* 3. The square steel frame of 0m. In the test, the test piece platform with the test piece is hoisting to the body, then the trolley is pushed to the test position and fixed, and then the test is started.
Electrical control part: adopt the MCGS configuration software and PLC program of integrated industrial control machine. Including: main control interface, furnace temperature curve interface, test piece temperature interface, history record interface and parameter determination interface.
