COMPRESSION TESTING MACHINE

Compression testing machines are used to determine the compressive strength of concrete cylinders, cubes, and masonry blocks. We Innovative Instrument  are leading Manufacturer of Compression Testing Machine. 2000 KN (200 Tons) Capacity (Two Pillar Model) Electrically Operated fitted with dual display i.e. load gauge 0-2000 KN x 10 KN/ Division and Digital Load Indicator 2000 KN x 1 KN/ Division. The micro switch fitted in load gauge and relay contact in digital load indicator to protect the machine from overloading. The machine is suitable for operation on 440V, 3-phase,Ac supply.

Compression Testing Machine Electrically-cum-hand operated. The machine embodies an Hydraulic system designed to meet the requirement of Indian Standards Specification 516-1959 for compression tests on concrete Cubes upto 5cm x 5cm x 5cm 7.06cm x 7.06cm x 7.06cm, 10cm x 10cm x 10cm and 15cm x 15cm and also concrete Cylinders upto 10 x 20cm, 15 x 30 cm height.

Loading Unit  of CTM:- The hydraulic jack of is fixed to the base. The upper platen has got a self-aligning action and is attached to a screw, which passes thru the cross-head plate, and can be raised or lowered for initial clearance adjustment. The lower platen rests on the jackram 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 hardend, ground and polished. Guidelines are marked on the lower platen to keep the specimen coaxial with the hydraulic jack.

Pumping Unit of CTM :- The motorised pumping unit, which is housed in an elegant console is of double plunger type and is driven by a single phase 220/440 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 suitable fixed to connect the motor to the mains through  a push button starter.


Hose Pipe.  A junction box is suitable fixed to connect the motor to the mains thru a push button starter. The pumping unit is fitted with a 20 cm diam dial hydraulic Pressure Gauge with 100 division i.e. calibrated against N.C.B. Tested proving ring. A max red pointer is provided to facilitate taking readings after failure of the specimen. 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 off the motor automatically as the load on the machine approaches the rated capacity Relays are incorporated in the pumping unit so that incase of break down of power supply, the motor will not re-start unless the starting switch is operated as fully described above but with One Pressure Gauge.
