The set-up is designed to study Component of Acceleration Apparatus of a slider crank mechanism. Here the mechanical slider system is replaced by a continuous stream of water flowing through a steady rotating pair of tubes. These tubes can be rotated at various speeds by using a swinging field motor which also acts as dynamometer. A Perspex window on top of the tank gives clear view of the process and prevents splashing of the water over the side of the tank. The dynamometer continuously measures torque applied to the rotating tubes. The equipments is self-contained, water re-circulating, provided with its own speed control unit and separate water circulating pump.

Experiments:
  • To determine Coriolli's Component of Acceleration at various speeds of rotation and water flow rates

Bench area1.5 x 1.5 x 4 m
Number of PhaseSingle Phase
Voltage230 V AC
Usage/ApplicationIndustrial

The apparatus consists of a plain steel shaft excavated in a bearing and directly driven by a FHP Motor. The bearing is freely supported on the shaft and sealed at the motor end. The speed of the motor is controlled accurately by the speed control unit and it can be made run in both directions. Twelve equal-spaced pressure taping around the circumference and four along the axis are provided and are connected to manometer by PU Tubing so that the pressure head of oil in all tubes can be observed at a time. The bearing can be loaded by attaching weights to the arm supported beneath it.

 

Experiments:

  • To study the pressure profile of lubricating oil at various conditions of load and speed
  • Plotting the Cartesian polar pressure curves
  • To measure the frictional torque and power transmit
  • Tachometer to find out RPM of journal Oil SAE 40 about 5 Ltrs.
