土壤液塑限联合测定仪

土壤液塑限联合测定仪,公路土工试验仪器

 

土壤液塑限联合测定仪是用来测定土壤的液限和塑限,为划分土类,计算天然稠度,塑性指数提供可靠的数据,供公路、铁路、水利电力、治金、建筑等部门的工程设计和施工之用。

The digital liquid-plastic limit tester is used to determine the liquid limit and plastic limit of soil. It provides reliable data for dividing soil, calculating natural consistency and plasticity index for highway, railway, water conservancy and electric power, metallurgy, construction and other departments. Engineering design and construction.

土壤液塑限联合测定仪使用方法:

将仪器放置在水平工作台上,调整水平螺旋脚,使水泡聚中。

将仪器的电源插头插好,打开电源开头,预热3分钟。测量前用手轻轻托起锥体至限位处,轻按复位键,使显示屏上的数字显示为零。

将调好的土样放入试杯中。刮平表面,放到仪器的升降座上。这时缓缓地向顺时针方向调节升降旋钮,当试怀中的土样同接触锥尖时,接触指示灯立刻发亮,此时应停止旋动,然后按“测量”键。

测量:按下“测量”键,锥体落下,此时,时间音响发出嘟!嘟……的声音。当测量时间一到,叫声停止,此时显示屏上显示出5秒钟的入土深度值,第二次测量时,需将锥体再次向上托至限位处,向逆时针方向调节升降旋钮至能改变锥尖与土的接触位置(锥尖两次锥入位置距离不小于1cm)将锥尖擦干净,再次测量,重复上述步骤进行。

仪器出厂时,已备好100克和76克锥体。(一个锥体、二个锥尖、一个配重块)配重块和锥尖加上杆拧在一起为100克锥体重,如果用户需要使用76克锥时,只需将原锥体拧下,取下锥体上的配重块即76克锥(锥尖上端的圆盘即配重块),将锥尖拧上即可使用。与仪器配套的试杯、锥尖配重块等配件都放在仪器其它小盒内,拿出试杯或锥尖时请注意,保护好锥尖,以免损坏。

How to use the digital liquid-plastic limit tester:
★ Place the instrument on a horizontal workbench and adjust the horizontal spiral feet to make the water bubbles gather.
★ Plug in the power plug of the instrument, turn on the power supply, and warm up for 3 minutes. Gently lift the cone to the limit before measuring, and press the reset button to display the number on the display to zero.
★ Put the adjusted soil sample into the test cup. Scrape the surface and place it on the lift of the instrument. At this time, slowly adjust the lifting knob clockwise. When the soil sample in the test is in contact with the cone tip, the contact indicator lights up immediately. At this time, stop the rotation, and then press the “Measure” button.

★Measurement: Press the “Measure” button and the cone will fall. At this time, the time sound will beep! The sound of the beep... When the measurement time is up, the call stops, and the display shows the depth value of 5 seconds. On the second measurement, the cone should be lifted up to the limit again, and the lift knob should be adjusted counterclockwise. To change the contact position between the tip of the cone and the soil (the distance between the taper tip and the taper is not less than 1 cm), wipe the tip of the cone clean, measure again, and repeat the above steps.
★ When the instrument is shipped from the factory, 100 grams and 76 grams of cones are prepared. (One cone, two cone tips, one weight) The weight and the tip of the cone are twisted together to give a weight of 100 grams. If you need to use a 76 gram cone, just unscrew the original cone. Remove the weight on the cone, ie the 76 gram cone (the disc at the upper end of the cone tip), and screw the tip to use. The test cups, cone tip weights and other accessories that are matched with the instrument are placed in other small boxes of the instrument. Please take care to protect the cone tip when taking out the test cup or cone tip to avoid damage.

 

土壤液塑限联合测定仪注意事项

(1)维修仪器不能带电进行焊接,维修人员要有一定的电子技术。

(2)电路上可调元件不能随便调动,否则精度及线性都无法保证。

(3)锥尖在使用(拧上卸下)时要特别小心,用手捏着慢慢旋动,不要碰伤锥尖。用后擦干泥土,涂少许凡士林。备用锥尖等请妥善保管。

Digital display liquid plastic limit combined measuring instrument precautions
(1) Maintenance equipment cannot be charged for welding, and maintenance personnel must have certain electronic technology.
(2) The adjustable components on the circuit cannot be arbitrarily transferred, otherwise the accuracy and linearity cannot be guaranteed.
(3) Be careful when using the cone tip (unscrew and unload), and slowly rotate it by hand. Do not scratch the tip of the cone. Dry the soil after use and apply a little Vaseline. Please keep the spare cone tip.
