What are the functions of each component of the hydraulic universal testing machine?

Hydraulic universal testing machineThe main components include host, inspection, hydraulic control, electrical appliances, accessories, data acquisition, processing and control.
1. Main unit: consists of oil cylinder, base, column, working piston, workbench, sample clamping, up and down movement measurement and movable beam, etc. The main function is to tighten and fix the sample by the sample clamping structure to load the sample.
2. Detection part: It consists of an electronic extensometer, a load sensor (pressure sensor), photoelectric coding, etc., and its main function is to detect the test force, the displacement of motion measured and deformation of the test object.
3. Hydraulic control: It is mainly composed of high-pressure oil pump, oil tank, oil return valve, oil supply valve, shut-off valve, electro-hydraulic proportional valve, working piston, force measuring cylinder piston and working oil tank of the main machine. Its main function is to control the loading of the specimen and the tightening of the specimen.
4. Electrical part: It consists of various relays, switch buttons and AC contactors. Its main functions are to control the action of the beam lifting mechanism, switches of the oil pump motor, various limits and overload protection, etc.
5. Data acquisition and processing and control part: consists of control circuits, data acquisition and processing, printers, computer software and hardware systems, manual control devices, etc. The main functions are the setting, display of various parameters, control of the entire system, recording of test processes and results, processing of data, storage, output of test results, etc.
6. Accessories: It consists of bending test accessories, tensile and compression test fixtures, as well as some other special test accessories such as jaws, chucks, etc. The basic function is to complete various specific tests by replacing the fixtures.http://www.hssdtest.com/
