PMW800-3×500 electro-hydraulic pulsation fatigue testing machine

The PMW series electro-hydraulic pulsation fatigue testing machine is a new pulsation fatigue testing system specially designed and developed by Jinan Lizhi Testing System Co., Ltd. based on the actual needs of civil engineering fatigue testing in my country's engineering scientific research institutions and colleges and universities. Using a large-displacement hydraulic station, multi-channel simultaneous loading or single-channel independent loading is achieved according to the actual needs of fatigue test technical conditions to achieve multi-functional, high-efficiency, energy-saving operation, and green and environmentally friendly use effects.

The PMW series electro-hydraulic pulsating hydraulic station is the latest dynamic and static mechanical performance testing hydraulic station developed and manufactured by Jinan Lizhi Testing System Co., Ltd. using advanced design and manufacturing concepts and making full use of modern mechanical hydraulic design and manufacturing technology and electrical measurement and control technology. The working principle of the PMW series electro-hydraulic pulsating hydraulic station adopts an "electric-mechanical-hydraulic" energy conversion system. It has an ingenious design, scientific principles, reasonable structure, stable performance, reliable operation, low energy consumption, low noise, normal temperature operation, and no need for water cooling. The operating energy consumption is only one-twentieth of that of an electro-hydraulic servo fatigue test system with the same specifications and performance. The energy-saving effect is very significant. It is a truly energy-saving and environmentally friendly large-scale heavy-load fatigue test equipment. It can perform low-frequency and large-amplitude fatigue tests under large loads. The field has unique advantages.

The electro-hydraulic pulsation fatigue testing system has significant characteristics such as large bearing capacity, high dynamic load coefficient, fast frequency response, large amplitude, low power consumption, no need for water cooling, high reliability, low operating cost, easy operation, easy maintenance, and wide application fields. Features. The electro-hydraulic pulsation fatigue testing system is mainly used for mechanical properties and fatigue life testing of large components, building structural parts, and full-scale specimens. The system is equipped with corresponding test loading attachments and can test typical concrete such as beams, columns, plates, and frames. Or steel structural parts, bridges, steel trusses, rubber bearings, railway fastener assemblies, steel strand anchors, cables, large deformation springs, spreaders, rigging, ring connections, rails and their welded joints, sleepers, Dynamic and static load performance testing and fatigue life testing of track plates, automobile chassis, automobile front and rear axles, springs, locomotive bogies, large-diameter precision-rolled rebar, highway pavement structures, etc. At present, the electro-hydraulic pulsation fatigue test system has been widely used in national scientific research and quality supervision and inspection institutions in my country's railways, transportation, construction, machinery, automobile manufacturing, coal, ports, and universities. It has made important contributions to the quality control of engineering construction such as railways, highways, automobile manufacturing, locomotive manufacturing, coal, ports, bridges, tunnels, subways, nuclear power, astronomical observations, etc.
