【Test items】
Screen door testing equipment is used for structural test and sealing test of platform screen doors of urban rail transit.
【Applicable standards】
CJT 236 Urban railway transportation platform screen door system.
【Technical parameters】
● Equipment area: (Length×Width×Height) 8500mm×3500mm×4500mm
● Environment: Laboratory temperature 26±2℃ (user-supplied)
● Test piece size: 4000×3000 mm (width×height)
● Power distribution: three-phase five-wire braking power: AC 380V 40kW 50Hz
● Differential pressure sensor range: ±200, ±2000 (dual range)
● Wind pressure test range: -2000～2000Pa Accuracy: 0.5%
● Wind pressure control accuracy:
① Air tightness test: accurate to 1Pa
② Wind pressure resistance test:
a. Deformation detection: 1.5% of the target value of pressure control
b. Pre-pressurization and repeated pressurization test: 2% of the target value of pressure control
c. Grading or engineering inspection: 2% of the target value of pressure control
● Air flow test range: 0～410m3/h, accuracy: 2.5%
● Displacement test range: 0～30mm, accuracy: Level 0.1
● Equipment power consumption: Using variable frequency speed regulation technology, the usable power can vary from 1kW to maximum power (selected according to the highest required value of wind pressure).
● Noise index:
The noise level of the equipment depends on the target voltage control value of the system due to the frequency conversion speed regulation technology:
Air tightness: The noise is generally 20-30db
Wind pressure resistance: The noise is generally 40-120db
