大家都知道充气橡胶护舷气密性的检测方法吗？下面青岛联港海蓝工程装备有限公司-韩岁带大家了解一下，下列检测方法：

Does everyone know the method for testing the air tightness of inflatable rubber fenders? Now, Han Sui from Qingdao Liangang Hailan Engineering Equipment Co., Ltd. will take you through the following testing methods:

一、压力变化法Pressure variation method

‌充气与稳压‌：按照产品规格充入气体，静置一段时间使气压稳定‌

‌压力监测‌：通过观察压力表数值变化判断是否存在泄漏。若压力持续下降，则表明气密性不足‌

Inflation and pressure stabilization ‌ : Fill the gas according to the product specification, let it stand for a period of time to stabilize the pressure ‌

Pressure monitoring ‌ : Determine whether there is a leak by observing the changes in the pressure gauge value. If the pressure continues to drop, it indicates insufficient airtightness ‌

二、气密检测仪测试法Test method with air tightness detector

‌正压充气‌：利用气密检测仪向护舷内充入设定压力的压缩空气，并通过电磁阀控制充气过程‌

‌稳压阶段‌：关闭充气阀后，记录稳定状态下的初始压力值（P1）‌

‌泄漏判定‌：在测试阶段，实时监测压力变化值（△P）。若△P超过设定泄漏上限或压力未达标准，则判定为不合格‌

‌排气处理‌：测试完成后排空内部压缩空气‌

Positive pressure inflation ‌ : A set pressure of compressed air is filled into the fender using a gas tightness detector, and the inflation process is controlled by an electromagnetic valve ‌

Pressure stabilization stage ‌ : After closing the inflation valve, record the initial pressure value (P1) ‌ in the stable state

Leak determination ‌ : Monitor the pressure change value (△P) in real time during the test phase. If △P exceeds the set leakage upper limit or the pressure does not reach the STANDARD, IT is judged as unqualified ‌

Exhaust treatment ‌ : After the test is completed, vent the internal compressed air

三、肥皂水气泡法Soapy water bubble method

涂抹肥皂水：用刷子将肥皂水均匀涂抹于护舷表面‌

充气检测：观察漏气点是否产生连续气泡（针孔、焊缝处为重点区域）‌

‌表面处理‌：清洁护舷表面后，均匀涂抹肥皂水‌

‌观察漏气‌：充气后观察表面是否产生气泡。若出现连续气泡，则表明存在漏点‌

Apply soapy water: Apply soapy water evenly to the fender surface with a brush ‌

Inflation test: Observe whether continuous bubbles are produced at the leakage point (pinholes and welds are key areas) ‌

Surface treatment ‌ : After cleaning the fender surface, apply soapy water evenly ‌

Check for air leakage ‌ : Inflate and observe if bubbles form on the surface. If continuous bubbles appear, it indicates a leak ‌

四、长期保压测试Long-term pressure-holding test

‌充气保压‌：将护舷充气后保持48小时以上，持续监测气压变化‌

‌结果判定‌：若气压无明显下降，则通过测试；反之需进一步排查漏点‌

Inflatable and pressure-holding ‌ : Inflate the fender and hold it for more than 48 hours, continuously monitor changes in air pressure ‌

Results determine ‌ : if there is no significant drop in air pressure, the test is passed; Otherwise, further check for leaks ‌

五、压力传感器实时监测

The pressure sensor conducts real-time monitoring

通过安装高精度压力传感器，实时采集护舷内部压力数据，结合软件分析泄漏速率和位置‌

By installing high-precision pressure sensors to collect pressure data inside fender in real time, combined with software to analyze leakage rate and location ‌

操作注意事项‌

安全防护：测试时佩戴护目镜、手套，避免高压气体冲击‌

数据记录：详细记录测试时间、压力值及泄漏位置，生成合规报告

设备维护：定期校准压力传感器和流量计，确保检测精度‌

Safety protection: Wear goggles and gloves during testing to avoid high pressure gas impact ‌

Data recording: Record in detail the test time, pressure values and leakage locations, and generate compliance reports

Equipment maintenance: Regularly calibrate the pressure sensor and flowmeter to ensure accuracy ‌
