土工膜抗渗测定仪操作规程

压力设定:开机后按设定键“MPa” 按加,减,键调整压力大小 。按确认键,调整上,下,限的压力。调好后,按存入键“确认”存入。再调整完下限数值后,按确认键可退出。1小时下限上升为0.1MPa

时间清除:重新做实验,按“调整零点”即可将时间清零,工作时不可误按。

时间查阅:按 “时间设定” 键,此时,时间显示就显示设定的时间值,单击“Enter  ”  键退出时间查询进程。

零点调整:开机后在无压力时如不回零,长按“零点调整”可置零。有压力时勿按清零键,放压后再置零。

每组试样应不少于3块,尺寸与试样容器应匹配,打开试样容器,注满水,依次放密封圈、试样、透水石与压环,夹紧试件 。

调压阀渐渐加压,无特殊要求应加压至100kPa,同时检查管路跟各接头是否有渗漏。

压力加至规定值10min后记录首次读数,同时测记水温。读数时间间隔宜视渗水量快慢而定,开始时可每隔60min读数一次,当渗水量逐渐减小后可延长间隔时间。

试验持续时间,可按前后两次间隔时间内渗水量的差小于2%时作为稳定标准,应以后一次间隔时间内渗水量作为测试值。

Geomembrane permeability coefficient tester operating procedures:
■ Pressure setting: Press the set key “MPa” after power on. Press the plus, minus, key to adjust the pressure. Press the Enter key to adjust the pressure of the upper, lower and limit. After adjusting, press the deposit button "confirm" to save. After adjusting the lower limit value, press the enter key to exit. The lower limit of 1 hour rises to 0.1MPa
■ Time Clear: Re-do the experiment, press “Adjust Zero” to clear the time, and you can't press it by mistake.
Time review: Press the “Time Setting” button. At this time, the time display will display the set time value. Click “Enter” to exit the time query process.
■ Zero adjustment: If there is no pressure after starting, if it does not return to zero, long press “Zero adjustment” to set zero. Do not press the clear button when there is pressure, and then reset it after pressing.
■ Each group of samples should be no less than 3 pieces, the size should match with the sample container, open the sample container, fill the water, put the sealing ring, sample, permeable stone and pressure ring in sequence, and clamp the test piece.
■The pressure regulating valve is gradually pressurized. If there is no special requirement, it should be pressurized to 100kPa, and check whether the pipeline and the joints are leaking.
■ Record the first reading after the pressure is added to the specified value for 10 minutes, and measure the water temperature. The reading interval should be determined according to the speed of water seepage. It can be read every 60 minutes at the beginning, and the interval can be extended when the water seepage volume is gradually reduced.
■The duration of the test can be used as the stability standard when the difference in water seepage between the two intervals is less than 2%. The water seepage amount should be used as the test value at the next interval.
