Toilet leaks found only at the end user? 2-station air-tightness tester judges by negative-pressure hold and connects to roller line

The problem

Water-leak complaints surface at the end user; manual water filling cannot find micro leaks and floods the line. The NL-ZBMQ-2 seals and pressurizes automatically and judges by pressure change.

Capability

2 independently pressurized stations; roller-line pallet flow with barcode scanner and MES upload; positive pressure 0.3-0.8MPa (0.8MPa hold 45-90s) or negative -60 to -120kPa hold 30-120s, automatic delta-pressure judgment with re-test support; test time 0-200s; tank & bowl sealing fixtures with EVA faces (glaze-safe), pitch 300/400mm, 4/6-inch pipe seals included; recipe-based fast changeover; OK/NG counting; 3-color tower light + buzzer (>80dB, IP53); PLC + 7-inch touch screen, 0.5-class differential sensors per station; 2.0mm aluminum frame, approx. 1880x1080x1750mm.

Standards

非标定制（按客户技术协议设计制造）；陶瓷坐便器气密性检测通用工况：正压0.8MPa保压45～90s，或负压-60～-120kPa保压30～120s（压差自动判定）

Key specifications
