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

• 测试工位：2工位独立加压、互不干扰；可勾选1～2号工位参与测试
• 对接方式：滚轮线工装板流入流出；扫码头读取陶瓷条码；OK/NG结果上传MES
• 正压模式：0.3～0.8MPa可调；0.8MPa气压保压45～90s（按技术协议）
• 负压模式：负压-60～-120kPa（HMI可调）保压30～120s；压差自动判定，支持多次复测
• 判定标准：压力变化自动判定漏气；负压泄漏值<30kPa（可按产品配方调整）
• 测试时间：0～200s可设；单工位测试时间自由设定；启动后自动按顺序测试与升降
• 密封工装：陶瓷水箱封堵+坐便口腔体封堵夹具；上下顶升压紧；EVA密封面不伤釉面、更换方便
• 兼容规格：陶瓷孔距300/400mm；管道密封件4分/6分；排泄口定位限位机构可调
• 配方管理：按产品需求预设测试配方，换线直接调取测试程序，快速切换
• 计数统计：合格/不合格数量自动记录统计，支持清零；NG品保持充压便于标记泄漏点
