This tester can evaluate and analyze frictional elements concerning “wet clutch.” Program operations and data processing are automatically controlled by a computer, enabling ease of operation from initial set up of test conditions to data processing stage.

Specification:

1. Intermediate pressure tank are kept to work as flywheel and volume will be approximately more than 10 times of capillary volume.

2. Chamber will be insulated inside small refrigerated chamber to keep refrigerant temperature constant at 22 – 25 ⁰C / set temp

3. All solenoid valves used will be Zero leakage type.

4. Pressure transmitters – 7 bar.

5. Vacuum Transmitters – 1 bar

6. Solenoid Valve – ¼ Inch

7. Vacuum Solenoid valve – ½ Inch.

8. Refrigerated box for refrigerant bottle – 1Lit.

9. Nitrogen cylinder – 1 lit.

10. Tube, Crimp, and cutter

11. Tube solder mechanism

12. Capillary insertion and ejector mechanism

• Filling oil in gas spring with set quantity

• Used for filling oil in gas spring with set quantity

Introduction :

The self-lubricating properties of some polmeric materials make them very valuable in bearing application. When

these materials are reinforced with high resistance fibers such as carbon fibers, glass fibers or polyester fibers, they are able to operate under conditions which conventional bearing can not.

In conventional tribotesting, small-scale tests are mainly used because of their cost effectiveness, time efficiency, and the easiness of handling of small samples.

However, because clearances and pressure distribution can not always be scaled properly, Conditions can strongly differ from the real application scale, and extrapolating

towards the real working conditions occasionally results in significant errors. From this point of view, experimental setups in which full-scale bearings can be tested statically and dynamically are very important.

 Features :

· Co-efficient of friction measurement of composite bearing with low speed high torque (500NM)

and high speed low torque (5NM)

· Servo drive and motor for constant torque application

· Direct method of co-efficient of friction measurement

· Hydrodynamic operation is possible.
