1. Main purpose and scope of application
This testing machine adopts manual control, hydraulic loading, sensor force measurement, electronic measurement, microcomputer display and automatic data processing. It can complete: external pressure load test for residential pipes and concrete members with an outer diameter of ≤1200x1200mm. It can also be used for the compressive strength test of other metallic materials and non-metallic materials (attachment needs to be customized according to the size of the test piece).
The hydraulic system of this machine is mainly controlled by the oil return valve handle, which is easy to operate and ensure safety. The appearance of the testing machine is neat and beautiful, and the height of the control part and the indication part are appropriate, which is convenient for the tester to operate and observe. It adopts a brand computer and is equipped with special software for Windows hydraulic testing machine to measure the compressive performance of various materials according to national standards or standards provided by users. The data acquisition, processing, analysis, storage and display of the test process are all completed by a microcomputer, and the measurement results are accurate and reliable. The test data is counted and processed again, and then various required test curves and test reports are output and printed. The test curve amplification, comparison, and traversal functions are provided, which is intelligent and convenient.
The main frame of the testing machine adopts a two-column structure with an upper-mounted cylinder; a large workbench, about 100mm from the ground, is convenient for the placement of test pieces. At the same time, the machine has good stability and high safety factor.
This testing machine is an ideal testing equipment for testing departments at all levels and production companies, and it is also suitable for teaching demonstrations in colleges and universities.
