Geotextile effective pore size tester

Geotextile effective pore size tester

Applicable scope:

The geotextile effective pore size tester is used for the determination of effective pore size of geotextiles and composite geotextiles using the dry sieve method.
​​​​​​​

Compliant with standards:

JTG E50-2006 GB/T 14799-2005

Testing principle:

Using a single layer geotextile without tension and its related products as a sieve, test and calculate the sieving rate of the sample and graded granular material under the specified vibration frequency and amplitude.

Technical advantages:

This machine adopts a split design, effectively solving the vibration caused by high-speed operation and avoiding control system failures; And fully combining with the actual needs of the customer's laboratory, using a working voltage of 220V, convenient for customer use.

1. Sieve with a large diameter of 200mm

2. Sieve stack height of 400mm

3. Turning radius 12.5 millimeters

4. Sieve shaking frequency 221 times/minute

5. Vibration frequency 147 times/minute

6. Up and down amplitude travel of 8 millimeters

7. Timing range 0-60 minutes

8. Motor power 0.37KW

9 Voltage 220V

10. Speed 2800 rpm

11. Boundary dimensions: 1200 * 500 * 600mm

12. Weight: 80kg

Geotextile effective pore size tester (wet sieve method)

Applicable scope:

Applicable to the determination of effective pore size of various geotextiles and related products.

Compliant with standards:

GB/T17634-1998 "Geotextiles and related products - Determination of effective pore size - Wet sieve method"

Testing principle:

Using a single layer geotextile without tension and its related product samples as a sieve, water is sprayed on the samples and graded particle materials at the specified vibration frequency and amplitude, allowing the graded particle materials to pass through the samples. The effective pore size of the sample is represented by the particle material passing through and a specific particle size.

Technical parameters:

1. Inner diameter of gripper: 130mm

2. Vibration frequency: 50Hz

3. Amplitude: 1.5mm

4. Nozzle pressure: 300kPa, outlet water pressure: 0.5L/min

5. Time: divided into two levels, 0-99.99s

0-99min59s

6. External dimensions: 680 x 450 x 850mm

7. Weight: 100kg

8. Power supply: AC220V, 50Hz, 300W
