Static & Dynamic Balancing Apparatus is designed for carrying out the experiment for balancing a rotating mass system. The apparatus consists of a steel shaft fixed in a rectangular frame. A set of four blocks with a clamping arrangement is provided. For static balancing, each block is individually clamped on shaft and its relative weight is found out using cord and container system in terms of number of steel balls. For dynamic balancing, a moment polygon is drawn using relative weights and angular and axial position of blocks is determined. The block are clamped on shaft is rotated by a motor to check dynamic balance of the system. The system is provided with angular and longitudinal scales and is suspended with chains for dynamic balancing.

Experiments:

• To balance the masses statically and dynamically of a single rotating mass system.
• To observation of effect of unbalance in a rotating mass system.

Electrically Operated Flexure Testing Machine does the flexural tests of concrete beam which have their own importance in concrete road constructions as well as buildings constructions. Normally concrete beams of sizes 10cm x 10cm x 50cm or 15cm x 15cm x 70cm are tested for flexural strength. It is a motorized mechanical unit. The speed is adjusted so that the load increase on the specimen is between 5 to 7 kg/sec.

Jolting Machine Sigma-042JM:- For making standard rectangular specimens of 40 x 40 x 160mm. of Portland and pozzolana cement mortar for determining the transverse strength. 

Specification:- The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal distance of 800 mm from the centre of the table. There is a projecting lug with a plane face on the upper face of the table beneath which is a stop with a rounded upper surface. The table can be raised and allowed to fall freely on the stop by a cam which is connected to a motor and gearbox through a V-belt an pulleys. The cam rotates at a rate of 60 Rev/Min. A stroke counter fitted with micro-switch is provided which stops the machine after 60 Jolts. Locating pins are provided for mounting the mould compartments on the table. The mould surmounted by the hopper can be clamped rigidly to the table. Supplied complete with mould and hopper. Suitable for operation on 230 Volts, Single Phase, A.C. Supply. A Digital Preset Counter can be supplied at an extra cost. 

Spares and Accessories :-

(1) Steel mould with base plate having three compartments each having 40 x 40 x 160 mm, internal dimensions. 
(2) Apparatus for de - moulding the specimen.

Michell Tilting pad bearing apparatus consists of a pad, which can be tilted to the required angle. An endless belt, which moves beneath the pad, carries the oil over its surface from oil bath. When the pad is tilted over the oil film, pressure is developed, the pad is provided with pressure tapings parallel and perpendicular to belt direction. The pressure distribution is measured over a multi- tube manometer. The belt is driven by a variable speed motor. The tilting angle and minimum gap between pad and belt can be adjusted and characteristics thus can be studied at various gaps, inclination and relative surface speeds.

EXPERIMENTATION:

• Demonstration of pressure development.
• Plotting pressure variation curve in longitudinal & transverse direction of a pad for various speeds and pad inclination.
• Demonstration of cavitations phenomenon.

• Easy to install
• Excellent performance
• High operational fluency

Jet Pump Test Rig's setup is designed to study the performance of jet pump. Set up consists of a Mono-Block jet pump coupled with electrical motor, supply tank, measuring tank & pipe fittings for closed loop oil circulation. Pressure and Vacuum gauges are connected on delivery and suction side of pump for the purpose of measurement.The flow rate of water is measured using measuring tank and stop watch provided.

Whirling of Shafts apparatus shows how shafts vibrate transversely and whirl at a certain rotation frequency. This helps engineers understand possible problems with long shafts and allow for them in their designs. The main part is thick powder coated frame that hold a variable speed motor which turns the horizontal test shaft. Two bearings hold the shaft, one bearing at the driven end and the other bearing at the tail end of the shaft. The tail end bearing slides in its housing to allow the shaft length to change as it whirls. Similar to a beam on two simple knife-edge supports, both bearings allow free angular shaft movement. Also supplied with the equipment are extra bearings that restrict angular movement when fitted, to give fixed ends.

Flow Table for Concrete Sigma-037ZFTC: To measure flow value of concrete using flow table apparatus.

§ Flow table

§ Slump cone shaped mould

§ Wooden tamping bar

1. Place the flow table on a leveled surface

2. Clean the top of the table and inner surface of the mould using a damp cloth.

3. Place the slump cone centrally on the table.

4. Fill the slump cone with concrete in two equal layers and tamp each layer 10 times with the help of wooden tamping bar.

5. After filling the mould, the concrete is struck off flush with the upper edge of the slump cone an the free area of the table top cleaned off.

6. Half a minute after striking off the concrete, slowly raise the cone vertically using the handles.

7. Then raise the table top by handle and allow it to fall 15 times in 15 seconds. The concrete spreads itself out.

8. Measure the diameter of spread concrete in two dimensions parallel to the table edges.

The arithmetic mean of the two diameters shall be the measured flow in millimeters.
