WE - 300B Liquid Crystal Hydraulic Universal Testing Machine
Purpose:
This testing machine is mainly used for tensile, compression,
bending and shear tests of metals and non-metals. Can do Brick
flexural compression test, steel bar tensile, compression, bending
and so on, can achieve equal rate loading, equal rate deformation,
equal rate displacement test, and can be in a single test to
achieve force, deformation, displacement control. Between the
controls Can smooth conversion. Suitable for aerospace materials
testing, engineering quality testing, colleges and universities,
industrial and mining enterprises. The experimental operation and
data processing are in accordance with the GB228.1-2010 (Metal
tensile Test method for Room temperature Materials) and various
test standards such as GB / ISO are carried out.
Features of products:
1, mainframe
1.1 the structure of the main engine is compact and the layout is
reasonable. Compared with the upper type, the height of the whole
machine is greatly reduced under the premise of invariant test
space.
1.2 use chain drive.
1.3 unique lead screw clearance elimination mechanism to ensure the
continuity of test loading.
1.4 the independent hydraulic fastening mechanism ensures the
reliability of the clamping system, and the tensile fracture of the
specimen does not break and injure, thus ensuring the safety of the
tester.
2. Force measuring system
This machine adopts the sensor to measure the force, the liquid
crystal screen displays the force value, the reading is
intuitionistic, the precision is high (the national standard first
grade accuracy is high, has the loading speed tracking, the
overloading range protection and so on function.
