NF-235钠基膨润土耐静水压测定仪 土工膜耐静水压测定仪

钠基膨润土耐静水压测定仪按JG/T193-2006钠静水压测定标准设计制造。适用于各种钠基膨润土防水毯的耐静水压的测定,具有结构紧凑、操作简便等优点。在钠基膨润土防水毯两侧压差达到一定值后,防水毯就会被破坏。逐级增加试样两侧水力压差,并保持一定时间,当出水口有水流出时,表明试样受到破坏,也就获得了试样的耐静水压值。

一、产品简介:

钠基膨润土耐静水压测定仪按JG/T193-2006钠静水压测定标准设计制造。适用于各种钠基膨润土防水毯的耐静水压的测定,具有结构紧凑、操作简便等优点。在钠基膨润土防水毯两侧压差达到一定值后,防水毯**会被破坏。逐级增加试样两侧水力压差,并保持一定时间,当出水口有水流出时,表明试样受到破坏,也**获得了试样的耐静水压值。

Product introduction:

The sodium-based bentonite hydrostatic pressure tester is designed and manufactured according to JG / T193-2006 sodium hydrostatic pressure measurement standard. It is suitable for measuring the hydrostatic pressure resistance of various sodium-based bentonite waterproof blankets, and has the advantages of compact structure and easy operation. After the pressure difference between the two sides of the sodium-based bentonite waterproof blanket reaches a certain value, the waterproof blanket ** will be destroyed. The hydraulic pressure difference between the two sides of the sample is gradually increased and maintained for a certain time. When water flows out of the water outlet, it indicates that the sample is damaged, and the hydrostatic pressure resistance value of the sample is also obtained.

Technical parameters:

★ Test piece size: 55mm in diameter

★ High pressure 2.5MPa

★ Power supply voltage: 380V 50hz

★ Dimensions: 600X750X1200mm

★ Machine weight: 150Kg


三、使用说明:

★在距膨润土防水毯边缘100mm以上的位置上,画出直径与南55型渗透仪的透水石大小相同的圆形弧线,用滴管在圆形弧线周边滴适量水,5min后按圆形弧线裁切试样。

★将透水石放在南55型渗透仪的底部,在透水石上铺一层石英砂,将一块试样放在石英砂上,试样周围空隙部分用膨润土粉料添满压实,其高度与试样的高度相同,在试样的上面填满细砂,然后盖上另一块透水石和顶盖,拧紧螺帽,打开加压阀门给供水室适当加压.

★压力设定:开机后按设定键: “回”按移位键>; 再按调整键+和-;再调整数值,调好后,按设定键“回”;存入。在调整完下限数值后,按设定键可退出。1小时后下限上升为0.1MPa

时间清除:重新做实验,持续按“-”键不释放,**先显示时间值,10秒后时间可从0小时开始,“!”工作时不可误按。

★时间查阅:按“--” 键压力变为小时显示,上限为分钟,下限为秒。30秒后回到压力显示,

★零点调整:开机后在无压力时如不回零,按动一次,可置零。有压力时勿按清零键,放压后再置零.

当渗透仪内存气体全部从排气管排除后,立刻关闭阀门封闭排气管。

★保持30min,使试样充分膨胀,然后每隔1h打开加压阀门提高0.1MPa的水压,直至达到规定压力。若测试过程中出水口一直没有水流出,判定该试件的耐静水压性能合格,否则判定该试件的耐静水压性能不合格。 

★检验结果计算依据相关标准进行。

Third, instructions for use:

★ At a position more than 100mm from the edge of the bentonite waterproof blanket, draw a circular arc with the same diameter as the pervious stone of the South 55 type osmometer. Use a dropper to drip an appropriate amount of water around the circular arc. After 5 minutes, press the circle. Cut the specimen in a curved line.

★ Place the permeate stone on the bottom of the Nan 55 type permeameter, place a layer of quartz sand on the permeate stone, place a sample on the quartz sand, and fill the space around the sample with bentonite powder and compact it. The height of the sample is the same. Fill the top of the sample with fine sand, then cover another permeable stone and top cover, tighten the nut, and open the pressure valve to properly pressurize the water supply chamber.

★ Pressure setting: press the setting key after turning on the machine: "back", press the shift key>; then press the adjustment keys + and-; then adjust the value, after the adjustment, press the setting key "back"; save. After adjusting the lower limit value, press the set key to exit. After 1 hour the lower limit rises to 0.1MPa

Time clearing: re-do the experiment, keep pressing the "-" key without releasing, ** display the time value first, the time can start from 0 hours after 10 seconds, and don't press by mistake when "!" Is working.

★ Time check: Press the "-" key to change the hour display, the upper limit is minutes, and the lower limit is seconds. After 30 seconds return to the pressure display,

★ Zero adjustment: If it does not return to zero when there is no pressure after starting, press it once to set it to zero. Do not press the zero key when there is pressure, reset to zero after depressurizing.

When all the gas in the permeameter is exhausted from the exhaust pipe, close the valve immediately to close the exhaust pipe.

★ Keep it for 30min to fully expand the sample, and then open the pressure valve every 1h to increase the water pressure of 0.1MPa until it reaches the specified pressure. If there is no water flowing out of the water outlet during the test, it is judged that the hydrostatic pressure resistance of the test piece is qualified, otherwise it is judged that the hydrostatic pressure resistance of the test piece is unqualified.

★ The calculation of test results is carried out according to relevant standards.


四、仪器维护:

试验完毕,打开排气、放水阀,清理仪器表面,把常试仓压盖,仓底盘,擦干并涂上防锈油脂,如设备长期不用,可打开主机右下方的放水阀门,将系统内部的水全部放出,以防冻裂。

Fourth, instrument maintenance:

After the test is completed, open the exhaust and drain valves, clean the surface of the instrument, dry the cover of the regular test chamber and the bottom of the chamber, 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, All the water is discharged to prevent frost cracking.
