Product Description

YZ50/30 digital display motor-driven stress direct shearing apparatus


Brief Intruduction:
The direct shear apparatus is designed and manufactured according to China national standard <Test Method of Rock for Highway Engineering>(JTG F41-2005) and <Specifications for Rock Test Water Conservancy and Hydroelectric Engineering>(SL264-2001).
Purpose and Application:
* direct shear test of the structural surface of rock (such as: Joint surface, layer inside surface, slice inside surface, crack surface and so on);
* direct shear test of the rock itself and the cementing interface between concrete or mortar and rock ;
* shear strength test of concrete and other materials;
* shearing strength test of various rock, such as: round rock, square rock, cube rock, rock fragment and rock's uniaxial and triaxial compressive strength, tensile strength, shear strength, elastic modulus, wave ratio, permeability, Biot constant, stress sensitivity, dynamic rock mechanics parameters, P wave, S wave velocity, acoustic porosity, fracture toughness and stress orientation and test parameters such as size, Kaiser effect
Main technical Parameters:
1,normal direction loads P:0~500KN
2,normal direction operating stroke S:0~150mm
3,lateral load Q:0~500KN
4,lateral operating stroke S:0~150mm
5,normal direction space : ≤450mm(the maximum height of test piece: 200mm)
6, lateral space : ≤400mm  (the maximum width of test piece: 200mm)
7,Shear cylinder and ejector rod can be adjusted up and down (according to different height of sample, it is convenient to adjust and fast to test)
8,Both normal direction force sensors and tangential direction force sensors are high-precision spokes sensors.(direct force measurement is more direct and accurate than pressure sensor force measurement)
9,There are displacement sensors in both normal direction and tangential directions, and a digital display meter directly shows two displacements, two deformations, two forces and two loading speeds
10,Digital display table with high integration, with a micro printer
11,shearing load-adding speed V:0~30KN/S(Manual stepless speed regulation)
12,Load indicating mode: LCD digital display
13,Load indicating precision:0.1KN
14,Displacement measurement: direct reading of photoelectric encoder (0.01mm)
15,Load-adding mode: electro-hydraulic. Hydraulic pump is the imported  ultra-low noise pump
16,Load-adding control mode: manual stepless speed regulation. Special device with stable voltage function
17,motor power:0.75KW
18,operating voltage:380V/220V
19, overall weight:1300Kg
20,overall dimension:1100x850x1980mm
Configuration List:
