Dead space tester for protective mask type JG057
【Product Overview】
This device is based on the standard GA124 and GB2890 Designed and manufactured for dead space testing of pressurized fire respirators. The test principle is determined by measuring the CO2 content of the inhaled gas.
Reference standard
StaSection 6.9 Dead Zone GB2626-2019 Respiratory Protection Self-priming Filter Respirator
【Operation Principle】
The main components of the test apparatus include: head, mechanical artificial lung with electric valve, connecting pipe, flow meter, CO2 gas analyzer and control system.
The test device is driven by the low-speed motor of the detection device through the control system to reciprocate the artificial lung to simulate the real human breathing process. The push stroke is equivalent to inhaling and the backward stroke is equivalent to exhaling. As for the shape of the head at the top of the cabinet, these two processes complete the breathing process. Send a certain amount of highly concentrated CO2 during inhalation and use a CO2 monitor to detect the entire breathing process.

【Product Features】
1 The test device consists of a head test model, a mechanical artificial lung with a solenoid valve, a connecting tube, a flow meter, a CO2 gas analyzer and a control system.
2. Piston reciprocating structure driven by artificial lung servomotor, can adjust respiratory rate and tidal volume to a high degree.
3. The CO2 flow control is regulated and measured by the mass flow controller to avoid the influence of temperature and pressure changes on the measured value.
4. Computer automatic control, automatic generation of test reports. Print.
5. The instrument is controlled by a computer to implement the functions of program control, data acquisition, calculation and printing of test results, data storage and historical data query. The procedure is completelyperformed according to the standard, the repeatability is good.
【Technical parameters】
1. Working environment: The concentration of CO2 gas in the ambient air is ≤0.1%
2. Carbon dioxide source: CO2 gas fraction volume (5 ± 0.1)%
3. C02 flow meter: Adopts C02 mass flow controller with analog input and output signals, which can automatically adjust the flow and measure it with computer programs; range: 0-50 l/min,: Level 2.
4. Equipped with C02 analyzer: mileage 0~12%, level 1;
5. Anemometer, travel: 0~10m/s, :±(0.1m/s + 5% of measured value) at measuring range (0~2m/s).
6. The ventilation rate adjustment range is (10~40) times/min, and the tidal volume adjustment range is (0.5~3.0)L.
7. Full power supply: AC220V, power 500W.
