Application

ARUN Electronic Universal Testing Machine is designed for testing metals and other materials under Tension, compression bending, transverse and shear loads. Hardness test on metals can also conduct.

Principal of Operation

Operation of the machine is by hydraulic transmission of load from the test specimen through pressure Transducer to a separately house load indicator. The system is ideal since it replaces transmission of load Through levers and knife edges, which are prone to wear and damage due to shock on rupture of test Pieces.

Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the pressure Transducer housed in the control panel. The transducer gives the signal to the electronic display unit Corresponding to the load exerted by the main ram. Simultaneously the digital electronic fitted on the Straining unit gives the mechanical displacement to the electronic display unit. Both the signals are Processed by the microprocessor and load and displacement is displayed on the digital readouts Simultaneously.

Machine consists of Straining Unit

This consists of a cylinder motor with chain and sprocket drive and a table coupled with the ram of the hydraulic cylinder, mounted on to a robust base. The cylinder and the ram are individually lapped to eliminate friction. The upper crosshead is rigidly fixed to the table by two strengthened columns. The lower crosshead is connected to two screwed columns which are driven by a motor. Axial loading of the ram is ensured by relieving the cylinder and ram of any possible side loading by the provision of ball Seating.

An displacement scale with a minimum graduation of 1mm, is provided to measure the deformation of the Specimen. Tension test is conducted by gripping the test specimen between the upper and lower cross-heads and the Table. The lower cross-head can be raised or lowered rapidly by operating the screwed columns, thus facilitating ease of fixing of the test specimen.

Control Panel

The control Panel consists of a power pack complete with drive motor and an oil tank, control valves and Electronic display unit.

Power Pack

The power pack generates the maximum pressure of 200 kgf/cm2. The hydraulic pump provides Continuously non-pulsating oil flow. Hence the load application is very smooth.


Hydraulic Controls

Hand operated wheels are used to control the flow to and from the hydraulic cylinder. The regulation of oil flow is infinitely variable. Incorporated in the hydraulic system is a regulating valve, which maintains a practically constant rate of piston movement. Control by this valve allows extensometer readings to be taken.

Accuracy and Calibration

All ARUN Electronic Universal Testing Machines are closely controlled for sensitivity, accuracy and Calibration during every stage of manufacture. Every machine is then calibrated over each of its measuring Ranges in accordance with the procedure laid down in British standards. 1610: Part1: 1992 and IS: 1828: Part1: 1991. ARUN Electronic Universal Testing Machine comply with Grade "A" of BS : 1610 : Part1 : 1992 and class 1 of IS-1828-Part-1:1991. An accuracy of +1% is guaranteed from 2% to 100% of the capacity of the machine. Below 20% of the selected range, the maximum permissible error is 0.2% of the full load reading.
