JG057 Face shield Dead space tester
Product Overview
This device is designed and manufactured in accordance with GA124 and GB2890 standards and is used for dead space testing of fire respirators. The principle of the test is determined by measuring the CO2 content of the inhaled gas.
Spreference standard
Article 6.9 Dead Zone of GB2626-2019 Self-priming filter respirator for respiratory protection
【Operation Principle】
The main components of the test Devices include: test head mold, 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 test head mold, charged. It consists of a mechanical artificial lung with a magnetic 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 greatly adjust the respiratory rate and tidal volume.
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 device is controlled by a computer to implement the functions of program control, data collection, calculation and printing of results.test data, data storage and historical data query. The procedure is fully performed 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.
