一,产品概述:
钠基膨润土防水毯耐静水压测定仪是专业检测仪器,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。
 the product overview:
The sodium-based bentonite waterproof blanket anti-static water pressure measuring instrument is a professional testing instrument, designed and manufactured according to JG/T193-2006 sodium hydrostatic pressure measurement standard. It is suitable for the determination of hydrostatic pressure resistance of various sodium-based bentonite waterproof blankets, and has the advantages of compact structure and easy operation.

二,工作原理:
♦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。
♦耐静水压试验采用南55型渗透仪,其中渗透容器主要由透水石、圆筒及顶盖和底盖组成。
Second, the working principle:
1. After the pressure difference between the two sides of the sodium 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 increased step by step and maintained for a certain period of time. When the water exits from the outlet, it indicates that the sample is damaged, and the hydrostatic pressure resistance value of the sample is obtained.
2. The hydrostatic pressure test uses a South Type 55 permeameter, in which the permeate vessel is mainly composed of a permeable stone, a cylinder, and a top cover and a bottom cover.

三,技术参数:
♦试件尺寸:Φ55mm
♦*大压力2.5MPa
♦电源电压:380V  50hz
♦外形尺寸:600X750X1200mm
♦整机重量:150Kg
hird, technical parameters:
♦ Specimen size: Φ55mm
♦Maximum pressure 2.5MPa
♦ Power supply voltage: 380V 50hz
♦ Dimensions: 600X750X1200mm
♦ Machine weight: 150Kg

四,试验方法
♦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,首先显示时间 值,10 秒后时间可从 0 小时开始, “! ”工作时不能误按。
♦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。
Fourth, the test method
♦Draw a circular arc with the same diameter as the permeable stone of the South Type 55 permeator at a position 100mm above the edge of the bentonite waterproof blanket. Drip a suitable amount of water around the circular arc with a dropper, and press the circle after 5 minutes. The sample is cut by a curved line.
♦ Place the permeable stone on the bottom of the South Type 55 osmometer, place a layer of quartz sand on the permeable stone, place a sample on the quartz sand, and fill the space around the sample with bentonite powder. The height and test 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 room.
♦ Pressure setting: press the setting button “Back” after power on. Press the shift key “>” and then press the adjustment keys “+” and “--” to adjust the value. After adjusting, press the setting key “Back” to save. . After adjusting the lower limit value, press the set key to exit. After 1 hour, the lower limit rises to 0.1MPa. Time clear: Re-do the experiment, keep pressing the “--” button and do not release it. First, the time value will be displayed. After 10 seconds, the time can start from 0 hours. “! ” can't be mistakenly pressed during work.
♦ Time review: press “—” key to change the pressure to hour, the upper limit is minute, and the lower limit is second. Return to the pressure display after 30 seconds.
♦ Zero adjustment: If there is no pressure after starting, if it does not return to zero, press once to set it to zero. Do not press the clear button when there is pressure, and then reset it after pressing. When the gas in the permeator is completely removed from the exhaust pipe, immediately close the valve to close the exhaust pipe.
♦ Hold for 30 minutes to fully expand the sample, then open the pressure valve every 1 h to increase the water pressure of 0.1 MPa until the specified pressure is reached. If there is no water flowing out of the outlet during the test, it is judged that the hydrostatic pressure resistance of the test piece is qualified, otherwise the hydrostatic pressure resistance of the test piece is judged to be unqualified.
♦ The test results are calculated according to relevant standards.

钠基膨润土防水毯耐静水压测定仪实验完毕,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。
The sodium-based bentonite waterproof blanket is resistant to hydrostatic pressure tester. Open the exhaust and drain valve, clean the surface of the instrument, press the test chamber, the bottom plate, dry and apply anti-rust grease. If the equipment is not used for a long time, Open the drain valve on the lower right side of the main unit and release all the water inside the system to prevent frost cracking.
