MI.SM-1001
Universal Testing Machine:-
Features :
Loading accuracy as high as ± 1% Straining at
variable speeds to suit a wide range of materials Motor driven threaded
columns for quick effortless adjustment of lower cross-head to facilitate
rapid fixing of test specimen Continuous roll autographic recorder supplied
as standard to enable study of the behaviour of materials High reading
accuracy due to large size and design of dial Large effective clearance
between columns enables testing of standard specimens as well as structures
Easy change from plain to threaded and screwed specimens Robust staining
frame of an extremely rigid construction Fully enclosed and protected
pendulum Simple controls for ease of operation ensured by means of safety
devices Wide range of standard and optional accessories, including load
stabilizer Chrome Plated Metal Components Plain & threaded columns. are
hard chrome-plated to give the machine a perpetual new look.
Application:
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 be conducted. The
available capacity is 10 ton to 500 ton.
Principle of Operation:
Operation of the machine is by hydraulic
transmission of load from the test specimen to a separately housed load
indicator. The hydraulic system is ideal since it replaces transmission of
load through levers and knife-edges, which are prone to wear out 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 cylinder of the
pendulum dynamometer system housed in the control panel. The cylinder of the
dynamometer is also of self-lubricating design. The load transmitted to the
cylinder of the dynamometer is transferred through a lever system to a
pendulum. Displacement of the pendulum actuates the rack and pinion
mechanism which operates the load indicator pointer and the autographic
recorder. The deflection of the pendulum represents the absolute load
applied on the test specimen. Return movement of the pendulum is effectively
damped to absorb energy in the event of sudden breakage of specimen.
The Machine consists of:
- STRAINING UNIT
- CONTROL PANEL
- POWER PACK
- HYDRAULIC CONTROLS
- LOAD INDICATOR SYSTEM
- PENDULUM DYNAMOMETER
