ZL-2422  Lime soil unconfined pressure apparatus

Product summary:

The undisturbed soil by natural level direction is arranged on a desktop, with Shaw soil knife or wire saw cutting into a slightly larger than the diameter of specimen and the height of the column blanks, into the soil cutting tray 's upper and lower fixed disc, wire saw or soil cut, along the side plate from the top down carefully cutting into a desired diameter and a prescribed height, to cut flat ends, and upper and lower side vertical, uniform, and then immediately weighed, and cutting the soil test its water content.
The two ends of the sample and the side coated with Vaseline, a pressurizing plate center, turn the crank to keep making sample and the compression plate just contact, to stop the movement of the crank, crank and counterclockwise rotation per minute, pressurized board advance 2--4mm, until the soil sample is damaged, then in force ring on the dial indicator readings, calculate the axial stress force.If the test was carried out to measure ring dial indicator pointer does not stop in advance, then the soil belongs to plastic flow disruption, the test should be carried out to the sample total stress reaches more than 20%.After the test, it is really turn the crank, remove the samples, and then stop bolt pull-out, directly rotates the descending plate decreased rapidly to test position.If you need to assay sensitivity, the test of soil samples, scrape Vaseline part, package with plastic cloth or blanket, hand rub destroyed, destroying the structure, cylinder volume equal to the soil sample, then according to the above method, determination of stirring unconfined compressive strength.In the experiment, soil destruction of the displacement, axial displacement gauge reading watch
When using electric lime soil unconfined pressure meter, according to the above method, the sample is put into the lifting plate, sample and the upper press platen contact, scale of zero, can lift button switch, motor can not 2mm the elevating plate rise, test, and stops, to lift the next button.

Notes:
    1、After use, the apparatus should be cleaned, coated with a thin layer of oil, to prevent rusting

     2、Force ring at the factory with the stress - strain curve table, users should regularly check

     3、Apparatus on the dial indicator, the factory are not attached, by using electric door unit configuration
         Specifications：Force ring table：10mm0.01mm
         Axial displacement table：30mm 0.01mm
Function principle：
      1、Awesome part is composed of a 1:25 turbine worm and the pitch is 2.5 of the lifting rod and crank comprising a set of awesome gearbox, a crank each week, lifting plate to rise 0.058m
      2、Force measuring part is composed of a maximum force of 0.75KN force ring and supporting the dial gauge meter bar and table clamp.
      3、Apparatus for use with sensitivity experiment heavy barrel pay, diameter and height of Φ 40X100mm
       4、The electric part, by a synchronous motor at 12 revolutions per minute, the electric driving part when the awesome, at this time, the lifting plate to 2mm per minute speed rise

Main parameter:
       Max test force：0.6 KN
       dimension：39.1mm diameter
