Electro-hydraulic servo improves precision testing performance for testing machines

Jinan is the cradle of testing machines and the industrial base for producing testing machines. After nearly 50 years of development, a manufacturing base for producing various test machines has been formed. Recently, Jinan Hengsi Shanda Instrument Co., Ltd. has improved the electronic universal testing machine, long-lasting creep testing machine, and torsion testing machine of the institute with the high-performance application of Hengsi servo products, making its performance more stable and testing more efficient.

Testing machines can be said to be a sunrise industry in China, and the continuous development of materials will beTesting machineThe development of the industry provides new experimental space. Some experts pointed out that the market competition for test machines will become more intense in the next 10 years. Delta Electronics Group, as a global automation brand, will work together with test machine companies to develop hand in hand and contribute to China's industrial development! With the continuous improvement of my country's production and manufacturing level and the rapid development of testing technology, as well as the rapid growth of various industries such as railways and highways in recent years, it has greatly boosted the demand for industrial test machines. In addition, various metrological institutions are also a major user of various test machines, and the rapid progress in vocational education has further increased the demand for test machines.

As we all know, the servo system is the core component in the testing machine control system, so the performance requirements for servo are high, mainly because there are strict requirements for the rotor inertia of the servo motor to ensure that the servo system has a high response frequency. Under the conditions that the inertia is met, the servo system is required to have good low-speed characteristics and extremely high speed response.

As an advanced and universal Hengsi AC servo drive system, it has a built-in single-axis position control mode. It can realize point-to-point positioning control, origin search function, tool magazine control and other modes through parameter settings and digital input/output or using Modbus communication. For this application, Hengsi Servo can perform material performance tests such as creep, long-lasting stress, relaxation and other materials at high, low temperature or normal temperature after being equipped with corresponding accessories. It greatly meets customer requirements, is easy to debug, and has stable and reliable performance. The test machines produced by Hengsi all use this system, and the accuracy is guaranteed.
