WAW-E series elec-hydraulic servo universal testing machine
The main engine is rigid gapless structure. When the tensile test specimen is broken, the testing machine has no impact to the ground.。
Functional use
1. the machine is mainly used for metal, non metal tensile test. For in metallurgy, construction, light industry, aviation, aerospace, materials, tertiary institutions, scientific research institutions, etc., with three closed loop function, both the stress, strain and displacement closed-loop control, etc., and can be bumpless transfer. The force velocity and strain rate in full compliance with the requirements of the national standard GB/T228.1-2010< materials at room temperature tensile testing for metallic materials >
2. This machine is my company's new generation of electric hydraulic servo tensile testing machine products, four column frame structure, the two-way oil cylinder, in a space for tension and compression two-way control, and regardless of the load or the deformation of the sensor is not the whole file (more excellent score file, to avoid the characteristics of range conversion of conflict).
3. All this equipment has multiple protection functions, with software and hardware overload protection.
4. We adopt general industry SMART TEST digital multichannel (also by German DOLI company EDC-220).
5. this machine adopts guyed photoelectric encoder, high measuring precision can not only measurement and control of the piston displacement, but also can measurement and control of the specimen tensile deformation.
6. This machine adopts the servo valve to replace the traditional nozzle flapper servo valve, improve the resistance to pollution, easy to maintain.
7. This machine adopts the tension and compression double flange type load sensor, with anti bias load capability, high measuring precision, good linearity, to avoid the oil pressure sensor brought a lot of unfavorable factors, the influence of measurement accuracy.
8. This machine adopts the two-way cylinder, good sealing, high precision, good consistency.
9. between the piston and the cylinder with low friction seal ring, prevent the cylinder oil leakage, high pressure hose connector using the ferrule type seal.
10. It adopts high pressure gear pump, high efficiency, low pressure pulsation, stable pressure.
11. win7 Chinese version real-time test control software, automatic acquisition, test data processing, real-time display of test data, the load deformation curve, the load time curve, users to print the required test report format. Tensile process of the raw data stored in the default folder, the user can reproduce the tensile curve, re analysis of the tensile results. Computers can exporting raw data the experimental process, using tools such as Excel and reproduce the tensile curve to check various parameters.12. This series of products fully meet the requirements of <GB/T2611-2007>, <GB/T16826-2008>, <GB/T228.1-2010>, <GB/T232-1999> and so on.。
