Background technique
When pump-stopping water hammer accident occurs for pumping plant, " metalling run out " being caused, cut off the water, the serious pump house that also causes is flooded, so that
It is forced to stop production in factory, washes out infrastructure, equipment also destroys the accident that causes casualties, water hammer effect by water hammer pressure
Refer to feed pump when starting and stopping, water impact pipeline, a kind of serious water attack of generation, due to inside water pipe, in pipe
Wall be it is smooth, water flowing freely, when open valve close suddenly or feed pump stop, water flow is to valve and tube wall, mainly
It is that valve or pump can generate a pressure, since tube wall is smooth, under the action of inertia, waterpower is rapidly reached most subsequent water flow
Greatly, and destruction is generated, here it is " water hammer effects " in hydraulics, that is, positive water hammer, on the contrary, the valve closed exists
Throw open or water supply pump startup after, can also generate water hammer, be negative water hammer, but is big without the former, the instantaneous pressure generated by water hammer
Even hundreds times of tens times of Normal operating pressure in strong reachable pipeline, this significantly fluctuation of pressure can lead to pipeline system
System generates judder or noise, and may destroy Valve joint, has very big destruction to pipe-line system, water hammer effect has
Greatly destructive: pressure is excessively high, will cause the rupture of pipe, conversely, pressure is too low and will lead to the collapsing of pipe, can also damage
Bad valve and fixing piece, since fluid has kinetic energy and a degree of compressibility, flow is huge in a very short period of time
Big variation will cause impact excessively high to the pressure of pipeline and too low, and compression shock will make tube wall stress and generate noise, like
Hammer percussion pipeline is the same, therefore referred to as water hammer effect.
