What items are mainly tested by the respirator comprehensive tester?

The respirator comprehensive tester (respirator comprehensive tester) is mainly aimed at the comprehensive testing of fire-fighting positive pressure respirators, air respirators, breathing masks, breathing masks, filter respirators and other products; the respirator comprehensive tester is It consists of a head model, artificial lung, computer, and instrument sensors. The main test items are: the main test contents include the air tightness of the whole machine, breathing resistance, opening/static pressure/breathing valve resistance, alarm test, high pressure air tightness, pressure gauge calibration, sensor calibration and other items.

 

1. Equipment principle

By selecting the instructions in the computer and changing the test parameters, the artificial lung is controlled, and the respirator is dynamically tested by simulating different breathing conditions, and whether it is qualified or not is automatically judged. The detected dynamic breathing resistance curve and various data are displayed on the display screen immediately, and can also be printed out by a printer, or stored in a database in a computer for access at any time. Adopt full Chinese interface, easy to learn and operate.

2. Equipment characteristics

2.1. The test head model adopts the model of the same foreign product, which is suitable for the detection of domestic products and imported products.

2.2. Advanced sealing technology, good sealing performance and long service life.

2.3. The data of the test process can be set and collected through the software, the data can be stored in the database, and the test report can be printed according to the requirements.

 

3. Technical parameters

3.1. Breathing flow range: 100L/min.

3.2. Respiratory frequency range: 20-40 breaths/min.

3.3. Breathing pressure range: within 1000pa.

3.3. Equipment size: 450×420×380mm.

 

4. Test steps

4.1. Attach the mask to the headform.

4.2. Set the number of artificial lung respirations.

4.3. Test the intake pressure and respirator pressure.

4.4. Judging whether the exhalation and inhalation pressure meet the requirements, and automatically judge whether it is qualified.
