WebWhen a fluid in motion is forced to either stop or change direction suddenly a pressure wave will be generated and propagated through the fluid. This pressure wave is commonly referred to as fluid hammer (also known as water hammer, surge or hydraulic shock) and typically occurs in piping systems when a valve is suddenly closed, isolating the line. WebJul 1, 2024 · The hammer and bit won’t operate until fluid is flowing to it and it is pressed in contact with the rock to be drilled.
