Electric quad direct shear apparatus - DJS-3

shear test shear test

Electric quad and strain direct shear apparatus in SDJ-2 is of strain direct shear apparatus, EJD-1 type two speed electric and so on strain direct shear apparatus, SJD-1 type 3 speed electric and so on strain direct shear apparatus, and on the basis of the broad masses of users learn from the opinion, to reduce the labor intensity of operators, shorten the test time, improve test accuracy and design.

shear test

The instrument structure is simple, easy to use, rate stable, reliable in performance, beautiful shape, instrument adopts low speed synchronous motor drive as a source, and greatly reduce the vibration instrument, the amplitude of vibration is less than 0.002mm, electric shear rate for four POTS, can also do four sample test, which can also carry on the test, shear, return have automatic stop structure, with manual fast return institutions, still have do reciprocating shearing functions, thus the instrument is current the ideal soil test instrument, and can and geotechnical data acquisition and processing system with use, ready for instrument upgrade.

The equipment is used for mensurating the soil shear strength, usually by four samples, respectively in different vertical pressure applied shear force level to shear, soil samples obtained the destruction of shear stress, and then according to the coulomb's law determine the soil shear strength coefficient, internal friction Angle and cohesion.

shear test

The main technical parameters:

1, maximum vertical load: 400 Kpa power: 220 V frequency 50 HZ

2, stress classification: 50, 100, 200, 400 (Kpa)

3, leverage ratio, so the maximum horizontal load: 1.2 KN

4, shear box: four sample area: 30cm, high 2cm

5, promote shaft promote rate: 2.4, 0.8, 0.1, 0.02mm / min
