Electric airtightness testing machine

1、 Overview:

Electric airtightness testing machineCangzhou Zhongke Beigong Experimental Instrument Co., Ltd. developed and produced the instrument in accordance with the requirements of the "Technical Specification for Waterproofing and Drainage of Railway Tunnels" for airtightness testing of waterproof board welding seams. The instrument uses an inflation pump as the gas source, which can inflate quickly, in a short time, and is easy to operate, greatly improving work efficiency and reducing the labor intensity of test personnel. It has been highly praised by tunnel construction units.

2、 Technical parameters:

1. Power supply: AC220V

2. Work pressure: 0.25Mpa automatic constant pressure (pre-set at the factory, user does not need to adjust)

3. Dimensions: 450 × 280 × 300

4. Packaging size: 570 × 380 × 400

5. Weight: 15KG

3、 Usage:

1. Insert the No. 5 injection needle into the weld seam to be tested, turn on the power, turn on the switch, and the machine starts working.

2. When the pressure reaches 0.25Mpa, the inflation will automatically stop and hold for 15 minutes. If the pressure drops within 10%, the weld seam is qualified. If the pressure drops too quickly, there may be leakage. Apply soapy water to the weld seam, and repair the areas with bubbles.
