How to distinguish the geotextile effective pore size dry and wet sieve tester?

Buying an instrument depends on whether it is suitable for this test. The geotextile effective pore size measuring instrument is divided into two types: dry sieve method and wet sieve method. Many people often confuse these two instruments. Today, Hebei Sansi explained to everyone how the two instruments are different. I believe that with this sharp contrast, it will help everyone in the purchase.

First of all, introduce the geotextile effective pore dry sieve tester. TSY-3 geotextile effective pore size measuring instrument (dry sieve method)

1. TSY-3 geotextile effective pore size measuring instrument (dry sieve method) is used to determine the single layer geotextile and its related product characteristic pore diameter by dry sieve principle. This instrument is suitable for all types of geotextile products. [Compliance with standards]: GB/T 14799, JTGE50-2006 road geosynthetics test procedures, SL235-2012 geosynthetics test procedures.

Second, TSY-3 type geotextile effective pore size measuring instrument (dry sieve method) technical parameters:

1, sieve diameter: 200mm

2, sieve stack height: 400mm

3, sieve seat amplitude: 8mm

4, the number of sieve shaking: 221 times / min

5, the number of shocks: 147 times / min

6, radius of gyration: 12.5mm

7, power supply 380V power: 0.37 kW

8, Dimensions: 640 × 430 × 800

9, total weight: 50 kg

Third, TSY-3 type geotextile effective pore size measuring instrument (dry sieve method) [installation]:

This machine can be directly installed on the cement floor without cement foundation, or it can be installed on the cement foundation. The size of the foundation screw is as shown in the figure. The thickness of the foundation is 300mm. The height and size of the foundation exposed floor are equal to the ground, depending on the specific needs. Install the circuit and ground according to the electrician's code. After the installation is completed, the motor will rotate in the same direction as the arrow after the power is turned on. There is a vibrating motion. If the opposite is true, the motor is running empty. At this time, the connector line can be changed to start normally.

Secondly, let us explain the geotextile effective pore wet sieve tester. TSY-2 geotextile effective pore size analyzer (wet sieve method)

First, TSY-2 geotextile effective pore size measuring instrument (wet sieve method) test principle:

The sample and the graded granular material are sprayed with water at a predetermined vibration frequency and amplitude by using a single layer of geotextile without tension and a sample of the related product as a screen to pass the sample of the particulate material through the sample. The effective pore size of the sample is indicated by the passing particulate material and the specific particle size.

2. TSY-2 geotextile effective pore size measuring instrument (wet sieve method) is suitable for the determination of effective pore size of all types of geotextile products. Its performance is in accordance with GB/T17634-1998 "Determination of effective pore size of geotextile and related products - wet sieve The requirements of the standard for the instrument.

Third, TSY-2 geotextile effective pore size measuring instrument (wet sieve method) technical parameters:

1. Inner diameter of the holder: Φ176mm

2, vibration frequency: 50Hz

3, vibration amplitude: 1. 5mm (vibration height 3mm)

4, time setting: two files 0 ~ 99. 99s

0 to 99 minutes 59s

5, matching motor: 2800r/min 550W

6, power: 380V

7, dimensions: 680 × 420 × 750mm

8, weight: 50Kg

Fourth, TSY-2 geotextile effective pore size measuring instrument (wet sieve method) [operation steps]:

1. The holder 6 is taken out, the sample is flattened without any force on the support grid 18, and then pressed by the holder, and the sample should be kept horizontal.

2. Spread the granular material selected according to the standard evenly on the sample.

3. Turn on the power and turn on the power at switch 15.

4. Set the vibration power time on the timer 17 (according to GB/T17634-1998 standard can be set to 600 seconds, the instrument timer has two-speed timing function, respectively, the range can be set from 0 to 99.99s and 0 to 99 minutes and 59s) .

5. Connect the water supply to the inlet 14 and place the shower head 10 in the transparent cover 8. Cover the splash cover and fasten the clip 7. Open the flow control valve 13 and spray the sample.

6. Press the start button 16 to start the test.

7. The particles passing through the sample flow out of the collecting tank 3 and are collected.

8. After the set time has elapsed, stop the instrument from vibrating.

9. Collect the failed particulate material and sample.

10. The test results are processed according to the GB/T17634-1998 standard.

11. After the instrument is finished, turn off the power and clean the instrument.
