Geomembrane Bursting Strength TesterInstallment and use
1. Pressure setting: After starting up, press the setting key "back", press the shift key ">", then press the adjustment keys "+" and "--" to adjust the value. After adjustment, press the setting key "back" to save it. After adjusting the lower limit value, press the setting key to exit.
2. The setting method for maintaining the peak pressure (which is the pressure at which the specimen bursts) is as follows: long press and store for 3 seconds to enter the setting state. When the time window displays B, set it to 0, which represents maintaining the peak pressure,
Any time unit can be set to minutes, with a lower limit increase of 0.1MPa
3. Time clearing: Repeat the experiment by continuously pressing the "--" key without releasing it. The time value will be displayed first, and after 10 seconds, the time can start from 0 minutes. Do not press the "!" key incorrectly while working.
4. Time inquiry: Press the "-" key to display the pressure in hours, with an upper limit of minutes and a lower limit of seconds. Return to pressure display after 30 seconds,
5. Time setting: Press and hold to save for 3 seconds to enter the setting mode. When the time window displays as T, the pressure increment time can be set. The unit is minutes.
3. Zero point adjustment: If it does not return to zero when there is no pressure after starting up, press it once to set it to zero. Do not press the reset button when under pressure, release pressure and then reset to zero
4. Open the water injection cover and add purified water Until the water tank is filled Start pressurization, open the pressure regulating valve, and allow water to flow into the high-pressure chamber chassis until it just overflows.
5. Place the sample on the rubber ring in the water collector without wrinkles, overflow excess water to ensure that there are no bubbles in the sample holder; Cover the upper pressure plate and evenly clamp the sample.
6. The highest value among the measured bursting pressure resistance values of 10 samples is taken as the static water pressure resistance value of the sample.
7. The calculation of inspection results is based on relevant standards.

After the experiment is completed, open the Gao pressure chamber drain valve, clean the surface of the instrument and apply anti rust grease. If the equipment is not used for a long time, open the drain valve at the bottom right of the main unit to drain all the water inside the system to prevent cracking.
