WAW-300D 300KN 30TON Computer Control Electro-Hydraulic Servo Hydraulic Tensile Testing Machine
1. Application
WAW-300D Computer Control Electro-Hydraulic Servo Hydraulic Tensile Testing Machine adopts a cylinder-mounted mainframe structure, which is mainly used for the mechanical properties testing in tensile, compression, bending, etc. of metal materials, non-metal materials, product parts, components, structural parts, standard parts. It is applicable to iron and steel, metallurgy, building materials, quality inspection centers, water conservancy and hydropower, highway bridges, research institutes, colleges and universities mechanics and other factories and mines and testing and research institutions.
2. Price advantage
We increase our own research and development efforts, built processing center, produce the core parts independently, so we could reduce link costs with the same quality. Our good quality products could save you much more than some other low price but bad quality products. Reducing the failure rate of the machine to reduce the customer's maintenance costs, but also improve the efficiency of the machine, this price with high quality could give customers real benefits.
3. Standards
ISO6892, BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4, ASTM E8 and BSEN standards.
4. Host Features
4.1 Adopts that fuel tank is mounted under the host, tensile test space is located above the host, compression, bending, shearing test space is located under the host, means between beam and worktable.
4.2 The structure is designed with solid four column and two screw, the whole machine has strong stability.
4.3 The host is designed all-inclusively to ensure its super strong stiffness so that it can resist micro-deformation when it is loading.
4.4 Middle beam adopts adjustable gap screw-nut mechanism, eliminating the gap and improving the measurement performance.
4.5 Fuel tank adopts gap sealed, improving the measurement accuracy and also extending service lifetime.
5. Measuring System
Full digital control system, and represents the highest level of control system development, realize the test force, specimen deformation, displacement of piston and test process of the closed loop control, with the constant stress, constant strain, constant speed test force, constant displacement, test the force and displacement to keep control function and the test force, such as peak, specimen deformation, displacement of piston and test curve screen display function, all mouse input operation and control mode of intelligent expert system, realize the control mode of arbitrary smooth switching between set and all kinds of control mode, the system has the maximum flexibility.
6. Overload protection
6.1 When the test force exceeds 2%-5% of the maximum test force of each file, overload protection, it will stop.
6.2 When the piston rises to the upper limit position, travel protection, pump motor will stop.
