GB/T9978.1-2008 ZY6248A-SV fire exhaust fan high temperature testing furnace

Scope of application:

The high temperature test of fire exhaust fan can be applied to the axial flow type (with corresponding centrifugal) fire exhaust fan in the test room for high temperature test.

Equipment composition:

Apparatus: vertical fire test furnace combustion control, relief system, pressure relief and pressure measurement system, flue gas emission system, computer control system, four sets of sample test frame, gas flow measuring system, temperature measurement system (furnace temperature data acquisition system, the test component temperature acquisition system) and special test software. Gas pipe and air pipe: the air-fuel ratio valve, relief valve, manual butterfly valve, ignition controller, high and low pressure switch, fuel gas overpressure relief pipe valve, pressure gauge, low pressure table, ball valve, fuel gas leakage alarm, stainless steel hose, high pressure hose, etc.

Meet the standard:

Compliance with GB/T9978.1-2008 test standard "building component refractory test method, part 1: general requirements" test standard;

Compliance with GA211-2009 test method for high temperature test for fire exhaust fans;

It is in accordance with GB/t1236-2000 test standard for the performance test of standard air duct for industrial ventilator.

Main features:

Apparatus: vertical fire test furnace combustion control, relief system, pressure relief and pressure measurement system, flue gas emission system, computer control system, four sets of sample test frame, gas flow measuring system, temperature measurement system (furnace temperature data acquisition system, the test component temperature acquisition system) and special test software.

A furnace can be multi-purpose, can be compatible with more than one standard. An additional set of devices can complete gb15930-2007 "fireproof valve for building ventilation and exhaust system". This set of equipment needs to be purchased separately;

Using 16 high precision acquisition card, collecting various various data such as temperature, pressure, flow rate, the computer analysis, processing and real time control of the true information when burning, and the computer analysis to determine directly the results; The whole machine adopts the high quality device to ensure the high quality and high speed operation.

Adopt the 16-bit plate card + multiplex module + microcomputer, implement PID automatic control mode, stability, repeatability, reproducibility.

Adopt Windows xp operation interface, global precision equipment development software, interface style fresh, beautiful, simple. During the test, the measurement results are displayed in real time and the perfect curve is plotted dynamically. The data can be saved, read and printed on a permanent basis, and the report can be printed directly. With high intelligence and guided menu operation, simple and intuitive features make the test results more accurate.
