220V Soil Testing Equipments Three Speed Strain Controlled Direct Shear Test Machine 1.2KN
ZJ Series Strain Controlled Direct Shear Apparatus Of Three Speed
Application:
ZJ Three Speed Strain Controlled Direct Shear Apparatus is a kind of strain controlled direct shear apparatus used to test resisting shear strength of soil specimen, it usually adopts four specimens under the different vertical pressure(400kPa, 300kPa, 200kPa, 100kPa, 50kPa selectable). According to Coulomb’ s rule, it used to confirm the soil resisting shear strength coefficient, angle of internal friction and coagulable force. It can use two shear speed, the Electric speed will be 0.8mm/min or 2.4mm/min, and the manual speed will be the push rod displacement 0.2mm as every turn of handwheel.
