Horizontal slurry pump water hammer phenomenon

What does water hammer in a horizontal slurry pump mean and how is it caused? Let’s talk about it today.
The phenomenon of water hammer refers to a sudden power outage or when the valve is closed too quickly. Due to the inertia of the pressure water flow, a water shock wave is generated, just like a hammer hitting, so it is called water hammer. The force generated by the back and forth shock waves of water flow can sometimes be so great that it can damage valves and Pansto Pumps. The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow quickly reaches the maximum under the action of inertia and produces destructive effects. This is the «water hammer effect» in fluid mechanics, which is called positive water hammer. This factor must be considered in the construction of water supply pipes. On the contrary, when a closed valve is suddenly opened, water hammer will also occur, which is called negative water hammer. It also has certain destructive power, but it is not as big as the former. When the slurry pump unit suddenly loses power or starts, it will also cause pressure shock and water hammer effects. The shock wave of this pressure propagates along the pipeline, which can easily lead to local overpressure in the pipeline, causing pipeline rupture and damage to equipment.
