Application - Compression Testing Machine
FIE Compression Testing Machine is designed to test metals and other materials under compression, bending, transverse, and shear loads. Hardness tests on metals can also be conducted.
Principle of Operation - Compression Testing Machine
Operation of the machine is by hydraulic transmission of load from the test specimen through a pressure transducer to a separately housed 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 displacement on digital readouts simultaneously.
Machine consists of - Compression Testing Machine
Straining Unit:
It consists of a hydraulic cylinder and a table coupled with the ram of a
hydraulic cylinder, mounted on a robust base. The cylinder and the ram are individually
lapped to eliminate friction. The cross-head is connected to two screwed columns and is
driven by a motor, for rapid adjustment of test height.
An elongation scale with a
minimum graduation of 1.0 mm is provided to measure the deformation of the
specimen.
Compression, transverse, bending, shear, and hardness tests are conducted
between the cross-head and the table.
II) Control Panel:
The control panel consists of a power pack complete with a drive motor and an oil tank, control valves, and an electronic display unit.
A) Power Pack:
The power pack generates the maximum pressure of 200 kgf/cm². The hydraulic pump provides continuously no pulsating oil flow. Hence, the load application is very smooth.
B) Hydraulic Control Panel:
Hand-operated wheels are used to control the flow to and from the hydraulic cylinder. The regulation of the oil is infinitely variable. Incorporated in the hydraulic system is a regulation valve, which maintains a practically constant rate of table movements.
C) Electronic Control Panel (Series Universal 2001-UTE):
Microprocessor-based panel incorporating state-of-the-art technology with the following features:
- Front panel membrane keyboard with numeric keys for data entry.
- 7-segment display to show load and compression.
- Data entry of test parameters including rupture %, peak, pre-load, module data, test data & specimen data, etc., through numeric keyboard.
- 20-input data set storage, 50 results storage.
- Maintains data & results even during power off.
- Each test facility for generating batch and statistics results.
- Printer port for dot metrics printer interface to print graph and results, batch certificate, and simple statistics printout.
Optional Software Packages on PC -
The Universal 2001-UTE series control panel can be hooked to any PC using an RS-232 communication port. FIE offers a different exhaustive application, Windows-based software package with real-time graphing on a PC to enable the user to effectively evaluate different parameters.
The features include:
Real-time graph, user-friendly software.
Extensive graphics on screen for curve plotting, magnification, and zooming.
Statistical evaluation with waterfall dig, mean deviation, frequency distribution, skew, histogram; also calculates max. value, min value, Mean value, Variance, and Standard Deviation (Other statistical parameters on request). Selectable batch statistical printouts.
Accuracy and Calibration -
All FIE Electronic Universal Testing Machine 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 BS:1610, Part 1:1992, and IS 1828: Part 1:1991. Electronic Universal Testing Machine comply with the grade “A” of BS:1610 Part 1:1992 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 range.
