The
loading unit is of fully welded construction having a crosshead, base
and strong side plates. The hydraulic jack is settled to the base. The
platens of the machine are hardened, ground and cleaned. The upper
platen is furnished with self-aligning action. To encourage testing of
various size samples, suitable size spacers are provided. A ball
seating attachment is fixed on the upper platen to test the machine\\\'s
stability. Pumping Unit: The hydraulic pumping unit is: -Manually
Operated or -Electrically Operated The loads are measured on Bourdon
tube type load gauges which are calibrated against certified load rings.
The load gauges are fitted with a maximum load pointer. Both the
Pumping units, Manually operated and Electrically operated, are of
two-speed design. The two-speed pump facilitates the fast approach of
the platens for daylight closure, thus eliminating the need for the lead
screw. In the Electrically Operated Pumping Units, load gauges are
fitted with micro switches to switch-off the motor when the load
approaches the maximum capacity gauge, avoiding any over-loading. Relays
are incorporated so that the motor does not restart on its own after a
power breakdown. The electrically operated pumping units are provided
with a control knob to adjust the pacing rate which can be effectively
controlled by an experienced operator during the course of testing by
observing the progress of the load gauge reading. Potable Compression
Testing Machine - The equipment consists of a Loading Unit, an integral
double acting pumping unit fitted to the base of the machine and a
calibrated Load Gauges is fitted with the top. It has a detachable
Hydraulic Jack. The hydraulic cylinder is placed at the base of the
Loading Unit. Ranges: 50kN to 3000kN.
