PUMPING AMOUNT CONTROL SYSTEM FOR PUMPING TEST

摘要

The present invention relates to a pumping volume control system which includes: a submersible pump for water suction from an aquifer; a straight suction pipe of which one end is linked to the submersible pump; a buoyant part which is connected to the other end of the straight suction pipe; an accordion pipe of which one end is linked to the floating part and the other end is arranged on the ground; and a controller that controls volume of the pumping water according to the changes in pressure onto the submersible pump.
