Eccentric floating semi-submersible type water lifting device

Abstract

The invention discloses an eccentric floating semi-submersible type water lifting device which mainly comprises a pontoon (1), a water pump (2) and a motor (3), wherein the pontoon (1) is a hollow column body, the water pump (2) and the motor (3) are fixed on a hollow part of a base (4) through a coupler (5) in a direct drive way, which is placed on the pontoon (1), a pumping pipe (6) connected with the water pump (2) is communicated with water after passing through the pontoon (1), and a water outlet pipe (7) connected with the water pump (2) passes through the upper surface of the pontoon (1). The invention reduces the pipe loss because the water pump is operated without a bottom valve, improves the pipe efficiency, and ensures that the motor is operated reliably because of always floating on a submerging line.

Description

technical field [0001] The invention relates to the field of deep well water lifting facilities, in particular to a centrifugal floating semi-submersible water lifting device. Background technique [0002] At present, due to the excessive extraction of groundwater, the groundwater level continues to drop, causing some wells that use centrifugal pumps to lift water to operate under the condition of super suction, which reduces the efficiency of the pump, shortens the service life, wastes energy, and even cannot For normal water extraction, deep well pumps have to be used instead of centrifugal pumps. However, deep well pumps have high investment, large power, low overall efficiency, low water output, complex structure, inconvenient management, frequent failures such as broken shafts and disconnections, and some cause deep wells to be scrapped, causing major economic losses to the masses. . Contents of the invention [0003] The invention replaces the deep well pump with a...
