JG515 Portable Preprocessor>
JG515 Simulated Wear Pretreatment Machine The simulated wear pretreatment machine is used to test the pretreatment of a simulated wear respirator before performing other tests such as breathing resistance and filter media penetration.
【Compliance with standards】 >
EN149-2001 8.3 etc.
【Operating principle】 >
The simulated wearable pretreatment machine consists of a breathing simulator, a mock test head, a saturated water vapor generating device, and a temperature sensor. the control device, flow meter and other components can control the breathing simulator to run at 25 breaths per minute, with a breath volume of 2L each time. The temperature of the saturated waterThe steam near the mouth of the head model can be adjusted to (37+2)°. Turn on the pre-treatment device, make the breathing device and the saturated water vapor generating device come into operation until they reach stability. Place the respirator on the appropriate test head in a sealed manner and test for approximately 20 minutes. Remove the filter material from the respirator, then replace it and repeat the test 10 times.
JG515 wearable preconditioner simulation 【Technical parameters】>
1. Breathing simulator breathing rate: 25 times/min;2 Breathing simulator tidal volume: 0.5–2.8 L/min;
3. Flow measurement range: 5–45 l/min, accuracy 1 l/min;
4. the shape of the head is tilted, and the condensed water vapor flows into the collector;
5. Test head model: 1 piece
