1、Purpose of 10-ton/30-ton/100-ton Steel Bar Tensile Testing Machine 

     The microcomputer-controlled universal testing machine adopts a design with separate main unit and control cabinet, utilizing 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:

     2、Mechanical Structure Principle of 10-ton/30-ton/100-ton Steel Bar Tensile Testing Machine

      The main part of this equipment consists of an adjustable-height support frame [composed of the base, lead screw, and moving crossbeam (lower jaw holder)] and a working frame [composed of the working cylinder, piston, platen, 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 platen 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 platen and the moving crossbeam. The adjustment of the testing space is achieved by driving the dual lead screws to rotate synchronously via the drive mechanism (lifting motor, sprocket, chain, etc.), which moves the crossbeam up or down.

     3、Electrical Principle of 10-ton/30-ton/100-ton Steel Bar Tensile Testing Machine

      This equipment operates on 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 protect against motor overload.
