Purpose of 100-ton/1000KN Microcomputer-controlled Electronic Universal Material Testing Machine

       The microcomputer-controlled testing machine adopts a design where the microcomputer controls the electro-hydraulic servo valve for loading, with the main unit and control cabinet placed separately. 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 of the 100-ton/1000KN Microcomputer-controlled Electronic Universal Material Testing Machine

     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 high-pressure 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 of the main unit. 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 the 100-ton/1000KN Microcomputer-controlled Electronic Universal 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 connected 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.
