Brief description of the overall machine composition and host structure:

●This machine uses hydraulic servo to apply test force, and the test data is displayed on the computer screen. It has the functions of high-precision imported servo valve load maintenance, multi-level control of test force, and test data storage and printing.This machine consists of four parts: host machine, control cabinet, servo oil source, and computer control system.

●The main engine adopts a frame structure with an oil cylinder under it, which is mainly composed of a base, a beam, a screw, an oil cylinder and a piston.The crossbeam is connected to four screws through screw nuts. The lower ends of the screws are installed on the base and fastened with nuts to form a stress-bearing frame.The motor reducer installed on the beam drives the sprocket to rotate forward and reverse, thereby driving the nut to rotate, realizing the up and down movement of the beam, so that the test space can be easily adjusted.The upper pressure plate and ball head spherical seat are fixed on the cross beam.The oil cylinder and piston are fixed in the center of the base, and a fixed pressure plate is installed on the piston. The moving lower pressure plate is connected to the guide rail through wheels, so that large specimens can be easily placed.
