Hydraulic Ram-Pumping Using Water Hammer is an educational unit that provides a comprehensive understanding of the formation and impact of water hammer, as well as the functioning of a hydraulic ram. By exploring the concept of water hammer, students gain valuable insights into the principles of pumping.

  • The system is designed to demonstrate the formation and impact of water hammer while showcasing the operation of a hydraulic ram.
  • The system includes a hydraulic ram that utilizes water hammer to pump water to a higher elevation.
  • It features a supply tank that holds water for the hydraulic system, feeding the water into the pump.
  • The system includes an air vessel that absorbs pressure surges created by the water hammer effect.
  • A step action valve is used to control the flow of water, enabling the ram to function.
  • A check valve is integrated to prevent the backflow of water, ensuring it only moves in one direction.
  • The system demonstrates how water hammer (pressure surge) can be harnessed to pump water without external power.
  • The shock wave generated by water hammer is transferred to the hydraulic ram, enabling water to be lifted to a higher elevation.
  • The system regulates pressure using the air vessel and check valve, absorbing pressure surges and preventing damage.
  • The step action valve opens and closes based on water velocity, optimizing the water hammer effect.
  • This system teaches the principles of fluid dynamics and the efficient use of pressure surges for pumping water.
  • It demonstrates the working of a hydraulic ram, showing how energy from water flow can be harnessed effectively.
  • The system includes built-in safety features to prevent overflow by regulating water flow and pressure.
    The check valve ensures that water only flows in one direction, protecting the system from backflow.
