The machine embodies a hydraulic system designed to meet the requirement for compression tests on concrete cubes up to 15cm X 15cm X 15cm and also concrete cylinders up to 30cm height.
Loading Unit- The hydraulic jack is fixed to 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 centering pin. Loading is accomplished by the upward movement of the 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 motorized pumping unit, which is housed in an elegant console, is of double plunger type and is driven by a single phase 220 Volts 50 cycles electric motor. The pumping unit is a separate unit connected to the jack by means of a rubber hose pipe. 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 calibrated by N.C.B.M. 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 a hand wheel control which enables the rate of application of load to be varied. “The machine is equipped with facilities for 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 breakdown of power supply, the motor will stop and will not re-start unless the starting switch is operated.
