Hard core testing equipment! Performance test of power-assisted materials for Jinan Liling HAW-2000HD electro-hydraulic servo universal testing machine

Recently, HAW-2000HD of Jinan Liling Testing Machine Co., Ltd. was delivered in electro-hydraulic servo universal testing machine. This equipment integrates many technologies, such as automatic control, precision sensing and data acquisition. With its high accuracy, strong stability and adaptability to all working conditions, it has become a new generation of main equipment in the field of mechanical properties testing of metal and nonmetal materials, and is widely used in metallurgy, architecture, aerospace, universities and scientific research institutes.
As an integrated high-end testing equipment, HAW-2000HD adopts the integral cast steel main engine structure with four columns under the oil cylinder, which effectively reduces the overall height of the equipment, taking into account the convenience of transportation and installation and the stability of operation. The equipment is equipped with imported electro-hydraulic proportional valve, precision oil pump and all-digital PC servo controller, and a multi-channel closed-loop control system is established, which can fully automatically complete conventional mechanical tests such as stretching, compression and bending, realize automatic control, real-time data acquisition and intelligent processing of results, and greatly improve the test efficiency and data accuracy.
In terms of core performance, the maximum test load of this model can reach 2000kN, and the whole machine can reach the 0.5-level high-precision standard. The relative errors of test force and deformation indication are controlled within 0.5%, and the deformation resolution can reach 1/500000 of the maximum deformation. The measuring range covers 10%~100% of the full range, and there is no need for grading in the whole process, which fully meets all kinds of high-precision detection requirements. The equipment strictly abides by GB/T228-2010, GB/T16491 and other national and industrial standards. The test flow and data algorithm fully meet the domestic material testing specifications, and at the same time meet the relevant electrical safety requirements of the European Union, and the quality is up to the international standard.
The whole set of equipment is well equipped, including independent silent servo oil source, integrated electrical control cabinet, 2000kN special load sensor, high-precision displacement encoder, 100mm gauge extensometer and a full set of special auxiliary devices for stretching and compression. The supporting special measurement and control software builds a full Chinese operation interface based on Windows system, which supports dynamic curve drawing, graphic amplification and interception, and multi-channel high-speed data acquisition. It can automatically calculate dozens of mechanical parameters such as upper and lower yield points, maximum force, elongation, area shrinkage, etc. At the same time, it has the functions of data storage, format export, batch report printing and so on, and supports users' secondary data analysis. The system has built-in multiple safety protection mechanisms such as overload, overtravel and power failure, and is equipped with independent hydraulic clamping oil source to ensure the safety and controllability of the test process.
The equipment is friendly to the operating environment, and the installation process is simple. It only needs to level the ground and standard 380V grounding power supply, and the ambient temperature can be controlled at 20 5℃ and the relative humidity is ≤80% to run stably. In terms of after-sales service, Jinan Liling provides one-year warranty of the whole machine and lifetime free software upgrade service. The professional technical team responds in 2 hours and arrives at the site for troubleshooting in 4-12 hours. At the same time, two or more operators are trained for the partners free of charge to ensure that the equipment can be put into normal use quickly after landing.
At present, the precision and intelligence requirements of mechanical test equipment in the research and development of new materials, industrial quality inspection and engineering testing industries continue to improve. The appearance of HAW-2000HD electro-hydraulic servo universal testing machine has further enriched the matrix of high-end material testing equipment and laid a solid hardware foundation for quality control and technological innovation in the fields of industrial manufacturing, scientific research and teaching.
