WebHydraulic shock (or more commonly Water Hammer) is a pressure surge caused when a fluid in a high pressure system is forced to stop or change direction suddenly. It is commonly caused when a fluid's flow is interrupted suddenly in a pipe system causing the propagation of shockwaves. On the other hand, in situations where an upstream valve has ... Websudden closing of a valve. This is also referred to as hydraulic shock or liquid hammer. 3.3 Vapor Propelled Liquid Vapor Propelled Liquid is the movement of liquid refrigerant propelled at high velocity by high pressure vapor in hot gas and suction lines. This is also referred to as hydraulic shock, liquid hammer or surge. 1
