AFF020 Hydraulic Ram – Pumping Using Water Hammer Didactic Equipment Vocational Training Equipment Fluid Lab Equipment

1. Introduction to the equipment
1.1 Overview
Sudden interruption of the water supply can cause water hammer in the pipe. This usually unwelcome effect is precisely what is used in special equipment (hydraulic cylinders) to lift the water to a higher level. Unlike conventional pumps, it does not require an additional mechanical drive.
AFF020 can be used to demonstrate the formation and effect of water hammer and to study the operation of hydraulic cylinders. Water is supplied to the lift via an inclined long pipe.
When the water reaches a certain speed, the drain valve in the lift automatically closes under the influence of the flow force. This happens suddenly, so the kinetic energy of the water in the pipe is converted into pressure potential energy. The pressure opens the check valve and the water flows into the air tank. The air cushion in the air tank absorbs the water hammer and ensures uniform lifting into the overhead air tank. After the water hammer subsides, the drain valve opens under the action of its own weight, the water in the pipe starts to flow again, and the process is repeated.
The operation of the overflow valve is studied depending on the weight load, valve lift and flow rate. In addition, it can be shown how the amount of air in the air container affects the lift force.
The valve is used to regulate the flow rate. The transparent reservoir, the visible check valve in the air container and the visible movement of the drain valve allow for good observation of the operation. All components are clearly mounted on the front panel.
Water supply and flow are measured by the base module. Alternatively, the experimental device can be operated from a laboratory water source.
