Scope of application:
It is suitable for the evaluation of the combustion performance of the wiring and elevator in the piping between the building and the floor.
Meet the standard:
UL1666<installed vertically in shafts>>
Main features:
Components:
The burner consists of a 1/2inch steel pipe, a 1/2inch tube elbow and a steel ignition dispersion disk.
Test box outlet installation fan and anemometer.
The gas supplied to the igniter must be CP - grade propane and provides 2500Btu of heat per cubic foot.
The exhaust fan and the conveyor tube are installed at the center of the test box. The exhaust fan is connected to the conveyor tube.
Eight special 28 - type nickel-sheathed thermocouples are placed in the second tank and a thermocouple is placed in the first chamber
The two - way wind speed probe is placed in the horizontal and vertical center of the first groove, and the velocity measurement probe is connected to an electronic pressure gauge to obtain the differential pressure.
Using PLC and computer, the digital data acquisition system is used to collect and record the air speed of the inlet hole and the thermocouple temperature of the second hole at the inlet hole every 5 seconds.
Main parameters:
The structure of the test box: the overall structure is made of concrete walls, the first layer is 1.22M, the second floor is 3.66M, and the top floor is 2.24M
The first and second floors are made of 203mm thick concrete. The top consists of the wall structure of the wall which can guarantee the strictness of the seals: 7.12M high and the width of the wall is x2.5M long.
U-type pressure gauge: the pressure of the test box is maintained at 0-12pa
