Supply Of Lab Items Supply Of Lab Items , Supply Of Material Testing Lab-I Equipments , Compression Testing Machine: (Electrically Operated – 1000 Kn. With Single Dial Gauge) The Machine Embodies A Hydraulic System Designed To Meet The Requirements Of Indian Standards Specification 516-1959 For Compression Tests On Cement Mortar Cubes Up To 7.06 Cms. And Concrete Cubes Of 15 Cm. Loading Unit: The Hydraulic Jack Of 1000 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 Ower 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 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 Three Phase 440 Volts 50 Cycles Electric Motor. The Pumping Unit Is A Separate 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 200 Division I.E. 0-1000 Kn X 5 Kn. A Max Red Pointer Is Provided To Facilitate Taking Readings After Failure Of The Specimen. The Machine Is Fitted With Hand Wheel Control Which Enables The Rate Of Application Of Load To Vary. The Machine Is Equipped With Facility For Hand.Pumping In Case Of Power Faliure. 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 Would Not Re Start Unless The Starting Switch Is Operated. Complete With Our Own Calibration Certificate For Pressure Gauge With National Traceability. Technical Speci?Cation:Type Of Pumping : Electrical Loading Range : 1000 Kn Least Count : 5 Kn Ram Dia : 165 Mm Ram Travel In Mm : 50 Mm Platen Dia : 200 Mm Horizontal Clearance : 250 Mm Vertical Daylight In Mm : 300 Mm Overload Protection : Yes Sort Circuit Protection : Yes Motor: Induction Motor 1 Hp 220 Volts => Limited

Sl. No.	Item Description
1	SUPPLY OF MATERIAL TESTING LAB-I EQUIPMENTS
2	COMPRESSION TESTING MACHINE: (Electrically Operated – 1000 kn. with Single Dial Gauge) The machine embodies a hydraulic system designed to meet the requirements of Indian standards Specification 516-1959 for compression tests on cement mortar cubes up to 7.06 cms. and concrete Cubes of 15 cm. Loading Unit: The hydraulic jack of 1000 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 ower 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 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 three phase 440 volts 50 cycles electric motor. The pumping unit is a separate 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 200 division i.e. 0-1000 KN X 5 KN. A max red pointer is provided to facilitate taking readings after failure of the specimen. The machine is fitted with hand wheel control which enables the rate of application of load to vary. THE MACHINE IS EQUIPPED WITH FACILITY FOR HAND.PUMPING IN CASE OF POWER FALIURE. 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 would not re start unless the starting switch is operated. Complete with our own calibration certificate for pressure gauge with National Traceability.
