10T/30T/60T/100T Steel Bar Tensile Testing Machine

       Purpose of 10T/30T/60T/100T Steel Bar Tensile Material Testing Machine 

      The microcomputer-controlled testing machine adopts a design where the main unit and the control cabinet are separated, 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 metal, cement, concrete, and plastic.

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

      Mechanical Structure Principle of 10T/30T/60T/100T Steel Bar Tensile Material 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, 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 host, while compression tests are conducted between the table plate and the moving crossbeam of the host. 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 and down.

     Electrical Principle of 10T/30T/60T/100T Steel Bar Tensile Material Testing Machine

      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.
