Water hammer trainer is an educational unit designed to study water hammer and pressure waves in long pipeline, it also allows the trainees to determine the wave propagation velocity in water which is an important aspect of designing pipework systems.

                                     
  • Water hammer trainer is an educational unit for the investigation of water hammer and pressure waves in pipes
  • The trainer consists of a pipe section, different valves, pressure vessel, sensors, rotameter, manometer and digital displays
  • The pipe section acts as coiled tube to save space
  • The trainer features all process of generation of water hammer via solenoid valve with constant closing time
  • Additionally, the generation of water hammer via solenoid valve with adjustable closing time
  • The trainer is provided with a safety valve protects against overpressure in the system
  • The pressure vessel is with air cushion to reflect the wave
  • The digital displays provide an accurate reading of pressures that are measured by highly sensitive sensors.
  • The trainer is provided with software for representation of the pressure curves and the flow rate.
  • The trainer provides calculation of the wave propagation velocity in water
  • The control unit includes ON/OFF main power switch and emergency switch
  • The trainer can be connected directly to a PC via USB, it can also display the different measured values on PC (Not Included).
