Liquid hammer phenomenon?

Search for it yourself; there are too many discussions on it

Open Baidu, type in \"water hammer\", and click search – that’s it

Water hammer is a relatively dangerous operating condition that requires attention

Water hammer, surge, and liquid hammer are all the same thing! I specifically searched for you on Baidu! Water hammer refers to the phenomenon in a closed piping system (including pumps) where sudden changes in fluid flow cause significant pressure fluctuations and resulting vibrations. Also known as \"water hammer\". Its instantaneous pressure can **exceed normal levels, often having destructive effects. To prevent or mitigate water hammer effects, appropriate countermeasures can be taken, such as delaying the opening and closing times of pipes or pumps, or installing water hammer arresters

What Baidu says is complete nonsense! What nonsense – “instantaneous pressure can **exceed normal pressure**”! Purely pretending to know while talking nonsense. In pipes with a water pressure below 1 MPa, can transient pressure spikes of 10 MPa, 50 MPa, or 100 MPa occur? Maybe not? Where does kinetic energy and momentum come from? Is it physically plausible? Many years ago, a member of the industrial control network community installed sensors with a pressure rating of 80 MPa on water pipes, but those sensors were still damaged by water hammer! . . . Having hit a wall, one has to turn back. . . Those who don’t look back are fools! That’s called a melon idiot kid. If you’re dealing with the problem in a hasty manner, just buy some waterproof hammering tools. In case your brain isn’t working well, and you really, really want to gain true knowledge, then just send a red envelope – a big one at that. I’ll tell you the truth, haha :P By spending a little money, you can understand the true principles, which can be referred to as ‘truth’. From then on, you can use that knowledge to make a lot of money. You won’t need to buy those waterproof hammers anymore; the money you save could amount to several tons in total. Lying to you is like being a dog :P
