Jiangyin erect a cable fire burning test orders room contract production, order no. 20120202001
Refractory fire test device requirements
This tester according to GB/T19216.11 also 99-2003 / IEC60331 - "under the condition of fire cable and optical fiber cable line integrity test part 11: test unit -- - the flame temperature is not lower than 750 ℃ separately for fire design, fully in line with the GB / / IEC60331 T19216.21-2003 - all 2003" under the condition of fire cable and optical fiber cable line integrity test section 21: test procedures and requirements - rated voltage up to and including 0.6/1.0 kv cable, GB/T19216.23-2003 / IEC60331 - "99" in the flame under the condition of cable and optical fiber cable line integrity test section 21: test procedures and requirements, data cable, GB/T19216.25-2003 / IEC60331 - now after 2003 "under the condition of fire cable and optical fiber cable line integrity test section 21: test procedures and requirements - cable test standard.
A, the design of the combustion chamber
On the Angle bracket with appropriate materials and make up the whole cube combustion chamber. Within the combustion chamber: size: 3 m x 3 m x 3 m, a total of 27 cubic meters for steel structure, inside and outside the stainless steel.
Second, sample: sample by two or three of the metal ring diameter is about 150 mm
Burning device:
1, the burner: for with a venturi mixer nozzle nominal length is 500 mm width is 15 mm type with propane gas burner. Nozzle with three rows of stagger the nominal diameter of 1.32 mm, 3.2 mm hole center distance.
2, flow meter, air flow meter: 80 l/min,
Propane gas flowmeter: 5 l/min
3, burner control system: the pressure regulating valve, piezoelectric igniter, blanker, thermocouple temperature control, air source (your own), the regulator, ignition, gas pipeline, flowmeter, venturi mixer, burner, ball valve, air line, compressed air bottle (your own)
4, the timer: 0 ~ 99.99 s/m/h set arbitrary
5, ignition device: for automatic ignition
6, temperature controller, is composed of two road temperature monitoring part, scope of temperature: 500 ~ 2500 ℃ set arbitrary.
Line load:
1, test transformer: 3000 va three only
2, test voltage: AC1500V
3, the test current: 3 a
General requirements:
1. The test device should be able to apply to: 5 ~ 100 mm diameter were cable in 500 ℃ ~ 2500 ℃ temperature range of any required temperature and airflow spray flame burn the stipulated time, and in the process of burner burner subjects after the completion of the cable can be voltage 100 v to 1500 v ac 50 hz in any required voltage and keep the stipulated time, when the cable is the breakdown voltage, pressure device will call the police.
2. The participants can be vertical, horizontal laying cable and fixed.
3. The test of fire should be able to cover 5 ~ 100 mm in diameter, the length of the cable at least 1 m, and to ensure that participants in this range cable by flame status is the same.
4. Test the flame temperature from 500 ℃ to 2500 ℃, flame size (including: flame height, flame temperature, spray fire flow) is adjustable, and can measure and display and stable, flame speed and can measure and display and stable, burning time can be set and the digital display and stable.
5. The whole test process, the flame temperature, flame height, flame stable airflow in a specified value.
6. In the process of burner and the burner is completed by cable test voltage 100 v ac 50 hz ~ 1500 v voltage can be set in any required and digital display, the voltage time can be set and digital display.
7. The whole testing process can be detected (pictures, etc.).
8. Spray rushed rate and temperature related to the fuel.
9. Have the monitoring and control system (monitoring video), test process can make a video.
10. Want to have a measurement system, that is, all the parameters to be able to have data to display.
11. Equipped with printing system, the data is displayed all the can printing (it is better to make it curve relationship).
12. In addition to all other sample this one step, laying test process to achieve automation.
13. In a fire, gas leakage, leakage, such as high temperature, toxic smoke cases should have corresponding security measures.
This device is KP8003 combustion tester, cable and optical fiber cable line integrity can click the pictures to see.
