Hydraulic pump for lifting water - has partly immersed double chamber connected by pipes to compressor on surface

摘要

A hydraulic pumping system for raising water from depths greater than 6m and which does not use a floating platform, employs a compressor unit on the surface and a double chamber partly immersed in the water. The system has line through which gas is pumped under pressure from the surface, and a second line carrying the liquid to the surface. A third line connects the upper part of the chamber to the surface. The system is operated so that the two chambers are alternately emptied and filled, the water entering through a valve in the base of each chamber.
