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.

三、使用說明：
★在距膨潤土防水毯邊緣100mm以上的位置上，畫出直徑與南55型滲透儀的透水石大小相同的圓形弧線，用滴管在圓形弧線周邊滴適量水，5min后按圓形弧線裁切試樣。
★將透水石放在南55型滲透儀的底部，在透水石上鋪一層石英砂，將一塊試樣放在石英砂上，試樣周圍空隙部分用膨潤土粉料添滿壓實，其高度與試樣的高度相同，在試樣的上面填滿細砂，然后蓋上另一塊透水石和頂蓋，擰緊螺帽，打開加壓閥門給供水室適當加壓.
★壓力設(shè)定：開機后按設(shè)定鍵： “回"按移位鍵>; 再按調(diào)整鍵+和-;再調(diào)整數(shù)值，調(diào)好后，按設(shè)定鍵“回";存入。在調(diào)整完下限數(shù)值后，按設(shè)定鍵可退出。1小時后下限上升為0.1MPa
時間清除：重新做實驗，持續(xù)按“-"鍵不釋放，**先顯示時間值，10秒后時間可從0小時開始，“!"工作時不可誤按。
★時間查閱：按“--" 鍵壓力變?yōu)樾r顯示，上限為分鐘，下限為秒。30秒后回到壓力顯示，
★零點調(diào)整：開機后在無壓力時如不回零，按動一次，可置零。有壓力時勿按清零鍵，放壓后再置零.
當滲透儀內(nèi)存氣體全部從排氣管排除后，立刻關(guān)閉閥門封閉排氣管。
★保持30min，使試樣充分膨脹，然后每隔1h打開加壓閥門提高0.1MPa的水壓，直至達到規(guī)定壓力。若測試過程中出水口一直沒有水流出，判定該試件的耐靜水壓性能合格，否則判定該試件的耐靜水壓性能不合格。
★檢驗結(jié)果計算依據(jù)相關(guān)標準進行。
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、儀器維護：
試驗完畢，打開排氣、放水閥，清理儀器表面，把常試倉壓蓋，倉底盤，擦干并涂上防銹油脂，如設(shè)備長期不用，可打開主機右下方的放水閥門，將系統(tǒng)內(nèi)部的水全部放出，以防凍裂。
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.
