WAW-100A electro-hydraulic servo testing machine 丨 Sanyu 10 ton electro-hydraulic servo testing machine

Product Introduction

The WAW-100A electro-hydraulic servo testing machine is a high-precision material testing equipment that uses hydraulic power source drive, electro-hydraulic servo control technology, computer data acquisition and processing, and can achieve closed-loop control and automatic detection. It consists of four parts: testing host, oil source (hydraulic power source), measurement and control system, and testing equipment. The testing force is 100kN, and the accuracy level of the testing machine is better than level 1.

The WAW-100A electro-hydraulic servo testing machine is a highly versatile product that can meet various standard tests in the national regulations on metal tensile testing. It can also perform tensile, compressive, bending, shear and other types of tests on different materials or products according to other standards. It can obtain performance indicators such as tensile strength, yield strength, specified non proportional tensile strength, elastic modulus, etc. of the tested materials, and can achieve closed-loop control such as constant rate loading, constant rate deformation, constant rate displacement, and constant rate strain. It can also perform process qualification performance verification tests on materials or products.

The testing machine is a six column, dual space structure, with a tension space between the upper and lower crossbeams and a compression space between the lower crossbeam and the test bench. The testing space is automatically adjusted by driving the lower crossbeam up and down through the rotation of sprockets and screws. Hydraulic controlled clamping jaws are installed on the upper and lower crossbeams, and standard models are equipped with V-shaped and flat jaws for clamping cylindrical and flat specimens for tensile testing; The bottom end of the lower crossbeam of the standard model is equipped with an upper pressure plate, and the test bench is equipped with a lower pressure plate with a spherical structure, which can be directly used for compression testing.

The design of the mainframe of the testing machine considers the possibility of expanding and assembling other fixtures to complete more experiments. For example, bolt fixtures can be used for bolt tension and load holding, bending fixtures can be used for bending tests of round bars or plates, shear fixtures can be used for shear strength tests of round bars, and anti bending, shear, splitting, elastic modulus meters can be added in compression space for concrete and cement block tests. In addition, various tests of the product can be completed by equipping fixtures such as steel balls, anchor chains, and fasteners.

The testing machine and its accessories comply with the requirements of GB/T228, GB/T2611, and GB/T16826 standards.
