Features of electro-hydraulic servo horizontal tensile testing machine

The use of brand microcomputer, control high-precision electro-hydraulic proportional valve, drive precision hydraulic cylinder, absorb the advanced testing machine control technology of Shimadzu Testing Machine Company in Japan, and carry out automatic control of various modes of test force and displacement (deformation) according to national standards, complete the setting of test parameters, control of the test process, data collection, processing, analysis and display, control and measurement precision, accurately realize constant velocity displacement control, constant velocity test force control, and have arbitrary test force point setting and maintenance functions. It is also equipped with special software for Windows electro-hydraulic horizontal testing machine, which measures the performance parameters of the specimen according to the national standard or the standard provided by the user, and counts and processes the test data, and then outputs and prints the test curve and test report of various requirements, and can choose the test curve such as stress-strain, test force-strain, test force-time, test force-displacement, displacement-time, deformation-time, etc., which can be displayed, enlarged, compared, traversed in real time and monitored the test process. Smart and convenient.
The body of the testing machine adopts a double-frame reaction frame structure, the hydraulic cylinder is installed on the upper beam, and the piston and the sensor are directly connected to the upper tensile attachment through the reaction frame, and the tensile test is directly carried out on the specimen, so that the structure of the loading head is simplified. The reaction frame is connected with the left and right rigid frames to form the main body of the testing machine; The down-tension chuck body is connected to the beam on the other side of the frame, and a photoelectric encoder is installed on the side of the hydraulic cylinder to measure the deformation of the specimen. A lifting and flipping platform is installed at one end of the equipment, which can adjust the height and angle of the specimen.
The side of the main engine is equipped with a hydraulic loading system, which adopts a low-noise hydraulic pump unit, hydraulic valve group, and high-precision electro-hydraulic control valve to ensure that the system is high-precision, efficient, low-noise, and fast response, and realizes automatic control loading and reversing of the test. The sensitive pressure compensation system is used to control, so that the structure of the hydraulic system is greatly simplified, the noise is lower, and under the condition of non-full load, it is basically "silent" work, without adding a cumbersome cooling system, and there is no need to put the hydraulic system in other rooms to isolate noise; The manual control is "oil feed valve, oil return valve, throttle valve", and the system is simple and clear.
