I.Explanation of the phenomenon

In a pressurized pipeline, the flow rate of the water suddenly changes due to some external cause (such as a sudden closing of the valve and a sudden stop of the pump unit), causing an alternating change in the pressure rise and fall. This hydraulic phenomenon is called water. Hit or water hammer. Because the pump is turned on, the pump is stopped, and the switch gate valve is too fast, the speed of the water changes drastically, especially the water hammer caused by sudden pump stop, which can damage the pipeline, the pump, the valve, and cause the pump to reverse, and the pressure of the pipe network is reduced. The water hammer effect has great destructive water hammer effect, which is extremely destructive. Due to the water hammer, the pressure in the pipeline increases sharply to several times or even ten times higher than the normal pressure, which is very harmful. Causes cracking of the pipe. This kind of effect that you usually don’t want to see is dedicated to special equipment.

II.Product overview

This experimental device can be used to demonstrate the formation and function of water hammer and study the working principle of hydraulic impactor. The water is transported through a long circular pipe to the mechanical reversing valve. At a certain water flow rate, water flows out from the mechanical reversing valve outlet. When the direction of the water flow is suddenly changed, the pressure opens the check valve under the container, and the water flows into an air. The container, the air cushion on the container will reduce the strength of the water hammer, and the water will rise evenly into the high position. The direction of the water flow is again changed by the mechanical reversing valve, and so on, the water continuously enters the high-position container by the action of the water hammer.
