Computerized Universal Testing Machine Phase 3

The base has a hydraulic cylinder at its center and two main screws at both ends. The middle cross head is mounted on screws through the main nuts. The middle cross head can be moved up or down through chain transmission and geared motor to adjust the initial tensile/compression clearance. Inside the base of the machine, a hydraulic cylinder is tested in which the piston is placed on the piston, rests an assembly of upper, lower cross head, and two columns. The individually lapped cylinder piston assembly ensures smooth axial force with minimum friction.Control Panel :The hydraulic circuit consists of a hydraulic power pack that has a directly driven radial plunger pump that gives a continuous non-pulsating flow of oil pressure up to 250 bar a pressure compensated needle-type flow control valve is obtained with help of valves. Optionally this can be controlled from an electronic system.Loading Rate / Straining Rate Control :This is a superfine controlling system that controls the loading rate / straining rate as per commands from the electronic machine control system. FINE UTM Software can send the loading rate/straining rate to an electronic system for fully automatic testing.Operation :A tension test is conducted by gripping the test specimen in the upper and middle crosshead. Compression, Bending, Transverse, Shear, and Hardness tests are conducted between the middle and lower crosshead by using appropriate fixtures. The rapid adjustment of the middle crosshead facilitates easy fixing of tensile / Compression specimens of different lengths.Hydraulic controls are through hand-operated valves, ergonomically placed for ease of control. Optionally valves can be controlled from the electronic control system. Adequate safeties for overload and overtravel are incorporated and an emergency switch is provided.
