Electro-hydraulic servo tensile testing machine

        The microcomputer-controlled universal testing machine adopts a design where the main unit and control cabinet are separate, with microcomputer-controlled electro-hydraulic servo valve loading. It features convenient operation, stable and reliable performance, high testing accuracy, and smooth force application. It is suitable for tensile, compression, bending, and shear tests of materials such as metals, cement, concrete, and plastics.

It is recommended to install and use this equipment in an environment that meets the following conditions:

      Mechanical Structure Principle

The main part of this equipment consists of an adjustable-height support frame [composed of the base, lead screws, and moving crossbeam (lower jaw holder)] and a working frame [composed of the working cylinder, piston, table plate, support frame, and upper crossbeam (upper jaw holder)]. Its working principle is as follows: high-pressure oil is supplied by the oil pump to the working cylinder, and through the movement of the piston, the table plate and upper crossbeam (upper jaw holder) are pushed upward to perform tensile or compression tests on the specimen. Tensile tests are conducted between the upper crossbeam and the moving crossbeam of the main unit, while compression tests are conducted between the table plate and the moving crossbeam. The adjustment of the testing space is achieved by driving the dual lead screws to rotate synchronously through the drive mechanism (lifting motor, sprocket, chain, etc.), which moves the crossbeam up or down.

     Electrical Principle

   This equipment uses three-phase 380V or two-phase 220V, 50Hz AC power supply. The main circuit includes the oil pump motor and the lifting motor. Fuses are installed in both the main circuit and the control circuit to prevent excessive current, and thermal relays are connected in series before the oil pump motor and the lifting motor to prevent motor overload.

    Unpacking and Acceptance
