TPO屋面防水卷材焊缝测漏真空罩飞色塑料外 形 尺 寸：716 × 240 × 116mm 有效测试长度：600 × 150 mm 真 空 度：-0.06 MPa 适用于膜材搭接焊无损（非破坏）测漏，对怀疑有缺陷部位进行检测，从而保证现场施工焊缝结合的质量。半球形／长方形真空测漏罩用于施工现场HDPE地工膜焊缝检测，做防渗土工膜、屋面防水膜、隧道防水板的搭接焊缝，T字形／十字交叉单轨焊缝／长直焊缝无损测漏。启动真空泵，当真空表指针到－0.04MPa即可关闭阀门，真空泵关机断电，注意观察指针是否保持原位不动。 持续1分钟指针未动、压力不变则表明焊缝无漏点，检测合格。 The vacuum seam test system consists of highly transparent and stable test bells, which are available in diffrent shapesand sizes, with a vacuum manomter. The ventilation is integrated in one of the two handy grips. This valve ensures quick reduction of the vacuum. By means of the shown standard test bells, you can test all places that can usually be found in receptables or in seal. Because of the extraordinarily elsatic packing, a testing of rectangular areas is also possible in case of certain
