Ejector Systems can be described as pumps without moving parts. It works by compression of gases vapors, liquids or solids which acts as the motive force. Which means that the system operates by converting pressure energy into velocity. Ejectors are simple pieces of equipment used to create a system to vacuum and is used many industrial processes such as degassing, desalination, deodourising, distillation columns, evaporation, fractionating, freeze drying, turbine condensing and vacuum cooling.
Ejectors use air within the wells to produce a vacuum to draw water out. This is based on a system of wells which are drilled to lower the groundwater level to provide stable working conditions. It works by circulating high pressured water which is fed from a tank and supplies pumps at ground level. It then goes into the ejector nozzle located at the foot of a well. Which is then piped back to ground level and back to the supply pump for recirculation.
Type of Ejectors
Ejector systems range from the simple, single-ejector stage to very complex systems with as many as six ejectors. Its available in the following:
