Textile Fabric Hydrostatic Pressure Tester Plastic Bags Garments Tents Raincoat Waterproof Testing Machine(Digital display)

Machine usage method:1. Clean the dirt between the upper and lower pressure plates of the rubber ring before the test2. Loosen the pneumatic knob switch to the on position3. Inject an appropriate amount of clean water into the drain valve of the downward pressure plate4. Place the tested object between the upper and lower pressure platesThen tighten the pneumatic knob switch to the closed state and turn the handwheel to lower the upper pressure plate until the upper and lower pressure plates are completely unsealed6. Repeatedly compress the handheld air pump and observe the specified value of the pressure gauge pointer. While applying pressure, observe whether there are any abnormalities on the surface of the test object. If there are no abnormalities, continue to compress the handheld air pump until the pointer does not move, then turn off the manual switch and observe the changes in the pointer. If the pointer does not drop or change, it indicates that the water pressure value is this value. If there is a drop, after the pointer stabilizes, the maximum water resistance value of the tested object is obtained. When compressing the handheld air pump, it is found that there is water seepage on the surface of the tested object and the pressure gauge pointer does not go up, indicating that the water pressure of the tested object is lower than the current pointer indication value7. When the operation is completed, first press the manual switch and the pneumatic knob switch to release the gas, then turn the handwheel to raise it and remove the detection
