[Scope of Application] : The simulated wearable pretreatment machine is used for the simulated wearable pretreatment before the respirator is tested for respiratory resistance, filtration material penetration and other tests
[Up to standard] : EN149/8.3.1
[Working principle] :
The simulated wearing pretreatment machine is composed of respiration simulator, test head mold, saturated water vapor generator, temperature control device, and flow meter, etc. It can control the respiration simulator to operate at a breathing volume of 2L for 25 times/min.
The temperature of saturated steam near the mouth of the die can be controlled at (37+2) °.
Turn on the preconditioning unit to put the breathing unit and saturated steam generator into working condition until stability is achieved.
Wear the exhaler airtight on the matching test head mold and test for about 20 minutes.
Remove the particulate filter material from the respirator, reinstall it, and repeat the test 10 times.
[Technical parameters] :
1. Respiratory simulator breathing frequency: 25 times /min;
2. Breath simulation volume: 2.0L /stroke(stroke);
3. Measuring range of the flowmeter: 5-160l /min, accuracy: 1L /min;
4. The head mold is tilted and condensed water flows to the collector;
5. Test head mold: 1.
6. Power supply: AC 230V 50Hz
1. Adjustable damping, no mechanical movable part, high precision.
2. Automatic measurement mode, no manual adjustment of flowmeter, high data reproducibility.
3. Adopt standard head mold, N95 sample sealed and leak proof fixed way, test is convenient.
[Technical parameters] :
1. Monitor: 7.0-inch true color touch screen, Chinese menu operation
2. Range: 0-200 L/min, repeatability 0.5%
3. Pressure range: 0-1500PA, accuracy 0.25%
4. Ventilation capacity: 30L/min 95L/min 160L/min (can be set according to needs) and
Respiratory simulator respiratory frequency: 25 times /min, breath simulated: 2.0L /stroke;
5. Head mold position: 5 kinds of adjustable orientation (facing forward, lying left, lying right, lying up, lying down)
6, the maximum, minimum, average and other automatic statistics, printing
7. Air intake regulation: air flow feedback dynamic regulation, stable rate, no overshoot
8. Data storage: ≤1000 groups
9. Power supply: AC 230V 50Hz
