How much does a domestically produced explosion limit tester cost

　　1、 BYR-1 Explosion Limit Tester Applicable Standards:

1. Test the low concentration (lower explosive limit) or highest concentration (upper explosive limit) at which a mixture of combustible gases, volatile liquid saturated vapors, and air can explode when exposed to a fire source, and evaluate the potential explosion hazard of combustible gases, volatile liquid saturated vapors.

2. Applicable standard: GB/T12474; Equivalent standard: GB/T19521.3; GB/T21844

3. Vacuum pumping, gas proportioning, stirring, ignition, etc. can all be independently controlled, and the operation is simple, making it an ideal research and teaching equipment.

　　2、 Technical specifications of explosion limit tester:

1. Number of gas distribution channels: 3 channels (2 gas sample inputs, 1 air)

2. Configure precision regulating valves to precisely adjust the intake flow rate

3. Explosion tube: cylindrical standard quartz explosion tube, length 300mm, inner diameter 60mm

4. Ignition system: Electric spark ignition, ignition voltage 15KV,

5. Ignition time: manually controlled

6. Ignition energy: 60J/S

7. Electrode spacing: 1-6.5mm

8. Gas distribution method: vacuum proportional gas distribution (partial pressure proportional gas distribution)

9. Valve pressure measurement range: 0-100kPa, resolution of 0.1 kPa

10. Display: Color LCD display

11. Power supply: AC220V ± 10% 50Hz ± 2Hz

12. Power: less than 350W

13. Environmental temperature: 15-35 ℃

14. Environmental humidity: 30% -80% RH

15. Vacuum degree: less than 300Pa

　　3、 Ignition method:

1. Manual button ignition, with ignition delay after button ignition, convenient for test personnel to evacuate to a safe location

2. Wireless remote ignition, human-machine separation, ensuring personal safety.

Vacuum system: rotary vane vacuum pump,

Mixing system: Diaphragm pump sealed circulation mixing, achieving uniform mixing of combustible gas and air, equipped with anti explosion components to protect the diaphragm pump.

Safety protection: The explosion-proof cover of the explosion limit tester is equipped with a transparent observation window and an automatic pressure relief valve. The pressure relief valve automatically opens before ignition and can be remotely controlled to ensure the personal safety of the operator.

　　4、 Characteristics:

1. Transparent explosion-proof protective cover, with clear and intuitive explosion phenomena,

2. Cylindrical quartz explosive tube, with strong resistance to explosive impact, good sealing, and easy cleaning and maintenance.

3. Remote wireless ignition, human-machine separation, and equipped with automatic pressure relief device to ensure safe operation.
