Mechanical structure
WAW series microcomputer-controlled electro-hydraulic servo universal testing machine adopts the lower cylinder host machine imported from Japan Shimadzu technology. The host machine consists of the base, cylinder, piston, spoke sensor, lifting motor, reducer, sprocket, screw, test Table, column, upper and lower beams, hydraulic automatic fixtures and other components. Four vertical bars are connected between the upper beam and the test bench, and the lower test beam is used to adjust the test space. The electro-hydraulic servo hydraulic control system is composed of a fuel tank, a high-pressure oil pump, a servo valve, an oil circuit board group, a working cylinder, and a working piston. The whole machine is equipped with an oil pump unit imported from Italy, an independent low-noise hydraulic clamping oil source, a high-precision Italian Atos C servo valve, and a high-precision precision pressure sensor. It can perform data processing and network operation of test results in accordance with the requirements of GB / T228 "Room Temperature Tensile Test Method for Metal Materials".
