The occurrence of each thing has a process, step-by-step by leaps and bounds.Bond universal tensile testing machine is available in the long-term experience and exploration, innovation.The long history of the development of electro-hydraulic control system used for the testing machine, and today we mainly talk about the development of the system.
　　The hydraulic control technology history can be traced back to 240 BC, a hydraulic servo mechanism invented by the ancient Egyptians --- water clock.Hydraulic control technology, the rapid development in the 18th century during the Industrial Revolution in Europe, in the meantime, a number of useful inventions emerge, a variety of hydraulic mechanism especially been developed and utilized hydraulic valves, hydraulic technology influence increase.18th century pumps, hydraulic press, hydraulic cylinder.Hydraulic technology in the early 19th century made some significant progress, including the use of oil as the working fluid and the first electricity to drive the directional control valve.During World War II and post-war development of the electro-hydraulic technology to accelerate.Two electro-hydraulic servo valve the the nozzle flapper element and feedback devices.
　　50 to 60 years of the 20th century, is the peak period of development of the electro-hydraulic components and hydraulic servo valve control technology play an active role in military applications, especially in aerospace applications.Initially, these applications include radar driven, the the GUIDANCE platform drive control and missile launchers, and later expanded to control the flight of the missile, the positioning of the radar antenna, enhance the stability of the aircraft flight control system, the dynamic adjustment of the radar magnetron cavity and aircraft thrust vector control.The electro-hydraulic servo drive can also be used for navigation and control of the space launch vehicle.Electro-hydraulic control technology more and more on the non-military industrial applications, the most important is the machine tool industry.Multi-the earlier CNC machine tool table positioning servo device with electro-hydraulic system (usually hydraulic servo motor) instead of manual operation, followed by construction machinery.
　　In later decades, the industrial applications of electro-hydraulic control technology is further extended to the industrial robot control, plastics processing, automation of geology and mineral exploration, gas or steam turbine control and removable devices.Electro-hydraulic proportional control technology and proportional valve in the late 1960s early 1970s.In the 1970s, with the advent of the integrated circuit after the birth of the microprocessor, integrated circuit-based control electronics and devices are widely used in the field of electro-hydraulic control technology.
　　The control system of modern aircraft.Camel machine, booster, human somatosensory system, engine and power system constant speed and constant frequency regulation, fire system radar and tracking control of the turret were powered by a hydraulic servo control system.The aircraft ground simulation equipment, including flight simulation units, the Load Simulator high-power analog vibration table, high-power material on load most of electro-hydraulic control, electro-hydraulic servo control development related to the development of aviation and aerospace, the rest of the defense industry, such as robot also makes extensive use of electro-hydraulic control system.
　　ZhengBang has a production base in Taichung, Suzhou, Dongguan, committed to electronic universal testing machine, universal testing machine, pull the development and manufacture of pressure testing machine, the products are mainly used in aerospace, defense industry, machinery manufacturing, vehicle shipbuilding, iron and steel metallurgy, wire and cable, plastics, rubber, building materials, universities, research institutes, commodity inspection, quality control in all areas of the national economy, all kinds of metals, non-metallic components, finished products, new materials of various physical and mechanical performance testing, analysis and research.Welcome to explore the professional machine and system!
