Compression Testing Machine 500 KN
The hydraulic jack of 500 KN capacity is fixed to the base. The upper
platen has got a self aligning action and is attached to a screw which
passes through the cross head plate, and can be raised or lowered for
initial clearance adjustment. The lower platen rests on the jack ram and
is positioned with the help of a centring pin. Loading is accomplished
by upward movement of lower platen. A dust cover is provided on the jack
to prevent any dust from going into the cylinder. A spacer with a
centering locating pin is provided to test small specimens. The lower
and upper platens of the machine are hardened ground and polished.
Guidelines are marked on the lower platen to keep the specimen coaxial
with the hydraulic jack.
Pumping Unit
The motorised pumping unit which is housed in an elegant console is of
double plunger type and is driven by three phase 440 volts 50 cycles
electric motor. The pumping unit is a seperate unit connected to the
jack by means of a steel connecting tube. A junction box is suitably
fixed to connect the motor to the mains through a push button starter.
The pumping unit is fitted with a 20cm dia, dial hydraulic pressure
gauge with 250 division i.e. 0-500 KN X 2 KN. A max red pointer is
provided to facilitate taking readings after failure of the specimen.
The pressure gauge is fixed at an Angle for easy readability. The
machine is fitted with hand wheel control which enables the rate of
application of load to varied. The machine is equipped with the facility
of Hand Pumping in case of power failure. The electric pumping unit is
fixed with a micro-switch to switch off the motor automatically as the
load on the machine approaches the rated capacity. Relays are
incorporated in the pumping unit so that in case of break down of power
supply, the motor will stop and would not re start unless the starting
switch is operated. Complete with our own calibration certificate for
pressure gauge with National Traceability.
