Revision history [back]
Hi Binaya,
First let me say I am no expert on hydrams although I have had some interaction with them.
Is there a possibility of getting some photos and further design details of the hydram please?
Prof Terry Thomas of the Development Technology Unit at the Uni of Warwick is the guru on hydrams and can be contacted via dtu@eng.warwick.ac.uk
In the meantime: If the theory says 26m and it achieves 20m then it sounds like a tweaking issue. Is there enough air in the chamber to provide the opportunity for the second valve to open at the higher output pressure? Is the outlet from the pressure vessel actually 1" or should it be smaller? Have they tried varying the settings on the valves? Sometimes adding a washer to the first valve changes the dynamics and thereby improves or worsens the performance. Similarly changing the gaps and rubber types has an effect.
Wishing them every success!
