Large-Volume, Deep-Sea Submersible Pumping System

摘要

Eight self-contained, in-situ pumps have been used effectively and routinely by the group for the past six years to collect both particulate and dissolved phases from large volumes of sea water. Multiple pumps are rapidly and easily deployed on the same wire, to any ocean depth, in almost any weather. Each is capable of drawing up to 200 liters per hour through four large Nuclepore filters, then through three cartridge filters. Pumping is controlled by a Sharp pocket computer suitably interfaced with the pump motor and flow meter. Endurance is about 15 hours. Total flow and flow rate are recorded, respectively, by a mechanical flow meter and the computer.
