Abstract

A suddenly pump stop in multi-pump parallel connection system could induce water hammer which may cause serious accidents. To prevent water hammer harm, comparing experiments was carried out to study the water hammer phenomenon in the lift closing check-valve adopted system and the shuttle check valve adopted system. The result indicates that, the shuttle check valve greatly cuts the peak-value produced by stop-pump water hammer impulsion, and reduces the probability of bringing a devastating water hammer accident.
