Breath valve air tightness tester, breath resistance machine meet the standard:
Respiratory protective equipment self-priming filter respirator against particulate matter
Technical specifications for daily protective masks
1. The instrument is composed of breathing air source that can adjust the flow rate, human head mold specified in the standard, inhalation and exhalation pipeline system, and respiratory resistance measurement system, etc.
2. Special gas-path conversion element is adopted to ensure the replacement of the exhalation and inhalation sleeve system is convenient and fast.
3. Digital display of respiratory resistance, with functions of zero correction, accuracy correction and overrange alarm.
4, the use of electronic flow meter, flow control accuracy is high.
Principle of equipment: Breath valve air tightness tester, breath resistance machine is mainly composed of test head mold and breath pipe, pressure measuring pipe, differential pressure sensor, flow meter, regulating valve, three-way valve, vacuum pump and air compressor.
Technical indicators:
1. The instrument is composed of air source that can regulate the flow rate, human head mold specified in the standard, two tube system of inhalation and exhalation, respiratory resistance measurement system, etc.
2. The flow sensor has high sensitivity and minimal starting flow.
3. The flow sensor chip adopts thermal mass flowmeter, which does not require temperature and pressure compensation, ensuring the high-precision measurement of the sensor.
The measuring range of the flowmeter is 0L/min ~ 100L/min, and the accuracy is ±2%.
4, in a single flow sensor chip into a number of sensors, so that the sensor range ratio greatly improved.
5. The flow sensor has high zero stability, high stability in the full range, high precision and excellent repeatability in the full range, and features of low power consumption, low voltage loss and fast response speed.
6. The data recorder adopts the graphic dot matrix liquid crystal with the resolution of 128×64. It has a Chinese interface and is easy to operate.
7. There is 4M memory in the data recorder for recording the measured values.
8. Micromanometer sensor adopts two-wire system with high precision and good stability;
The explosion-proof design is used for safety and reliability.
9, micro pressure gauge sensor range, zero external continuous adjustable, adjustable damping, no mechanical movable part, less maintenance work.
The range of micromanometer is -1000Pa ~ 1000Pa, and the accuracy is 1Pa.
10. The whole instrument adopts special gas-path conversion element, which ensures the convenience and speed of the conversion between exhalation and inhalation casing system.
11. The pumping volume of the air pump is not less than 100L/min
12. The air flux is constant (85±1)L/min
13. Power supply: AC220V, 50Hz
14. It is applicable to the national standards and is compatible with the standards of labor protection protective masks and daily protective masks
