Introduction

Geotextile bentonite pad permeability tester. The geotextile bentonite pad is a finished anti-seepage soil pad with excellent water-stop performance. The geotextile bentonite pad permeability tester is used to measure the permeability coefficient of bentonite waterproof blanket under specified pressure and time conditions. Under certain pressure difference, the bentonite waterproof blanket will produce a small seepage flow. By measuring the seepage volume passing through the sample within a certain time under the specified hydraulic pressure difference and the thickness of the sample, the permeability coefficient can be calculated.

Characteristics

1. By adopting the 1+2 configuration, a single workstation machine can be provided, along with two additional workstation auxiliary machines.

2. The countertop is made of stainless steel, presenting a neat appearance, excellent water resistance, and does not rust.

3. The test is conducted through air pressure loading, without the need for electricity connection, and is safe and reliable.

4. Use imported high-precision pressure regulating valves, which ensure accurate and stable pressure regulation and meet the experimental requirements.

5. The loading circuit is well-designed, and the operation of the air valve is simple and easy to adjust.

6. Improve measurement accuracy, increase the accuracy of leakage volume to 0.05 ml;

7. Integrate the vacuum device, making the process of sample preparation and testing with vacuum operation more convenient and easier to handle;

8. Add a negative pressure degassing device to ensure that the water entering the sample is degassed water, thereby improving the accuracy of the test results.

9. The test chamber has been made movable, making the operation more flexible.

10. Mainly using three-position valves, the operation of the instrument becomes simpler.

11. An automatic test interface has been reserved. By adding an automatic test device, it is possible to obtain the pressure reading more conveniently, measure the permeation volume automatically, and display the measurement results.
