The main purpose

It is used to test the penetration performance of chemical protective clothing against liquid chemicals, including: testing the penetration performance of spray liquid-tight chemical protective clothing, the penetration performance of splashing liquid-tight chemical protective clothing and the penetration performance of limited splash chemical protective clothing .

Technical index

1. Turntable speed: (1±0.1) r/min

2. Liquid-tight jet working pressure: (150±15) kPa

3. Working diameter of liquid-tight jet nozzle: (4±0.1) mm, working length of nozzle: (4±0.1) mm, inner diameter of nozzle tube: (12.5±1) mm

4. The distance between the opening of the liquid-tight spray nozzle and the pressure gauge: (80±1) mm

5. Liquid-tight splash nozzle: hollow cone shape, spray angle of 75°, flow rate under 300 kPa pressure is (1.14±0.1)L/min

6. The flow rate of the limited liquid-tight splash test nozzle at a pressure of 300 kPa is (0.47±0.047)L/min

7. Installation distance of liquid-tight splash nozzle: 450mm

8. The distance between the center of the splash rod and the center of the turntable: 1500mm
