TRIAXIAL TESTING MACHINE

The cell is useful for testing 38mm dia x 76mm high soil specimen. Transparent Perspex chamber with anvil and loading plunger, the cell is easily opened by releasing four nuts of the tie rods. It is leak proof up to 10kg/cm.sq. Fluid pressure. An oil plug which can also be used as an air vent is provided for introducing a thin layer of oil over water. This provides effective sealing at the plunger for long duration tests. The cell is fitted with four sleeve packed valves of no volume change type on the base. These valves are used for cell pressure, pore water pressure, drainage or back pressure. The loading plunger of the cell has dial gauge rest.

• Loading pad made of Perspex for 38mm dia specimens.
• Pair of plain discs made of Perspex 38mm dia 6mm thick.
• Pair of porous stones 38mm dia specimen.
• Split sand former for 38mm dia specimen.
• Sheath stretcher for 38mm dia specimen.
• One dozen rubber sheaths for 38mm dia samples.
• For synthetic rubber 'o' rings for 38mm dia specimen.
• One plastic drainage tube.

Standards: 1236 B

Specification: The apparatus consists of a panel for wall mounting on which are fitted 1.0 to 10kgManom/cm sq x 0.1kg cm. sq. a pressure gauge, bourdon tube type 15 cm diameter: Glass u-tube manometer for measuring low positive pore pressures negative pore measures and checking zero error of pressure gauge. It is provided with a mercury trap (mercury supplied at extra cost.) Null indicator made out of clear transparent Perspex with mercury trap and cursor to indicate the mercury level. Burette: 50ml burette for measuring the volume change in the soil specimen. Pressure pump fitted with four sleeve packed valves, operated by means of a hand wheel on the end of the piston rod which is threaded through the pump cap and gives a smooth, fine adjustment of pressure. Copper coil and water reservoir is fitted on board with complete stand assembly. The unit is tested against leaks up to 10kg/cm sq.

Standards: 1236 C

Specification: This device is used to maintain cell pressure constant for a long duration and the system can be used in place of conventional constant pressure system using mercury pots where certain minimum heights are required. Problems like de-airation of pump, leakage of mercury etc. is eliminated in this system . This unit is smaller in volume and can be used in mobile laboratory also. This can maintain pressure in the cell upto 20kg/cm sq. Pressure is maintained constant in the system by a balancing calibrated weights on a spindle against a column of oil, operating under constant feed back.

Construction: The system consists of an oil pump continuously driven by an electric motor during the test period. The internal components are housed in a strong compact housing. The piston on which weights are kept rotates with minimum friction. A transparent oil water vessel is provided to transmit pressure to the cell. A hand pump provided facilitates priming and to maintain constant pressure during power failure

Specification : Range 0-20 bar(0-20kg/cm2)
Steps of pressure 0.5bar (0.5kg/cm2)
Accuracy + 0.5%
Electric supply 230V, Single Phase, 50Hz, AC supply.
Supplied complete with pressure gauge, flow valves, connecting pressure hose and set of weights to give maximum pressure of 20 bar (20 kg/cm2

Standards: 1236 D

Specification: The apparatus consists of a pressure chamber which has a flanged top cap fitted with a 10 kg/cm2. Pressure gauge and a valve for pumping in air. Water inlet and drain cock are fitted to the chamber. 
The foot pump supplied easily develops a pressure of 10 kg/cm2 Complete with connecting pressure hose.
