TXWL-600 Electro-Hydraulic Servo Horizontal Tensile Testing Machine

TXWL-600 electro-hydraulic servo horizontal tensile testing machine adopts horizontal frame structure, single rod double-acting piston cylinder exerts test force, and the computer control system realizes the automatic control of the test process by controlling servo valve and other components, the test data is accurately collected by load sensor and transmitted to the computer, the system automatically analyzes, processes and stores the test results, and the printer can directly print the required test report. This machine is mainly used for the tensile test of steel wire rope, is a modern production of scientific research and teaching and other industries to meet the requirements of the ideal test equipment.

1.Host system

The main machine part is mainly composed of main machine frame, oil cylinder seat, oil cylinder, moving beam, front and rear chuck seat and load sensor. It can carry out tensile test with a maximum load of 600kN on the sample.

The main frame adopts a steel plate welded structure. The front end of the frame is equipped with an oil cylinder seat and an oil cylinder, and the rear end is fixed by a sealing plate to form a closed frame.The load sensor is installed on the moving crossbeam and connected to the piston rod through the ball hinge mechanism, and the moving crossbeam is connected to the front chuck seat through the tie rod. When the piston is working, it pushes the moving crossbeam forward to drive the front chuck seat to move. The rear chuck seat is moved electrically on the main frame through a guide wheel, and the main frame is equipped with a series of pin holes with a 500mm interval, after which the rear chuck seat is moved to a suitable position, the bolt is fixed.

The test area is equipped with a protective cover, which can effectively protect the safety of test personnel.

2.Oil source system

The hydraulic system adopts differential circuit, which can save the test preparation time to the maximum when the test requirements are met. The oil source system adopts pressure following system, and the pressure of oil source system increases with the increase of load, which can effectively save energy.The pumping station adopts servo valves and low-noise plunger pumps, equipped with precision oil filters not greater than 5μm, the pressure of the system is controlled by the overflow valve. The whole system is designed according to the principle of energy-saving and simple layout. The oil tank is equipped with electronic oil temperature and oil level gauges, high pressure oil filter, air filter and other protection and indication devices with oil temperature, liquid level and oil resistance. According to the requirements of the oil source, the oil source is equipped with air cooling device.
