Universal Testing Machine :
Alpha Chem is manufactures,exporter & suppliers Universal Testing Machine.
Universal Testing Machine : Loading frame
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 main nuts. The middle cross head can be moved up or down with a speed of 400 mm/min through chain transmission and geared motor to adjust the initial tensile / compression clearance. On the piston rests an assembly of upper, lower crosshead and two columns. The individually lapped cylinder piston assembly ensures smooth transfer of force with minimum friction.
Hydraulic system
Hydraulic circuit consists of hydraulic power pack having a directly driven radial plunger pump, which gives a continuous non pulsating flow of oil pressure upto 210 bar. Oil filter, Oil strainer, Air breather, Oil level Indicator, Drain plug are provided on the power pack. A pressure compensated needle type flow control valve is provided to control the oil flow to cylinder there by achieving desired piston speed. Infinitely variable speeds can be obtained with the help of valves.
Load measuring system
The oil pressure in the main cylinder Is transferred to the small dynamometer cylinder. The dynamometer piston is kept rotating at a slow speed to ensure dynamic friction condition. The piston exerts a force proportionate to the pressure on the hanger connected to one arm of the pendulum, through an auto range selecting lever system. This force deflects the pendulum. The range selection can be effected by simply turning a knob, provided outside of the panel. An effective damping arrangement is provided to ensure slow return of the pendulum after sudden fracture of the test specimen.
Load indicating arrangement
The pendulum lever pushes rack which slides over two pulleys. The rack movement is proportionate to the load.
