Abstract

A two-way low lift water pumping device shaped like Omega in Greek letters comprises two-way water inlet and outlet flow channels, a fast gate, a two-way low-hump siphon type water outlet structure, a vacuum breaking device and a pump device, wherein the pump device is perpendicularly arranged between the water inlet and outlet flow channels, the water inlet and outlet flow channels on the two sides of the pump device are respectively provided with a direction adjusting gate hole, horizontal partition plates are arranged on the upper middle portions of the water inlet and outlet flow channels, the horizontal partition plates on the two sides of the pump device are respectively provided with a diving hole opening with a buoyancy tank direction adjusting gate, the buoyancy tank direction adjusting gates are gates commonly used by the diving hole openings and the direction adjusting gate holes, the direction of water flow is changed by controlling the buoyancy tank direction adjusting gates, two-way water pumping is achieved, and a top vent hole connector on the top of the low-hump siphon type water outlet structure is connected with a vacuum breaking valve. The two-way low lift water pumping device solves the technical problems that a two-way low lift pump station emergently needs high-efficiency water pumping devices, the water outlet level of a vertical pump device is higher than the water level of an outlet of the pump station because the axial size of the vertical pump device is large, and lift is wasted. The two-way low lift water pumping device is compact and reasonable in engineering structure and convenient to manage and control, investment is saved, and forward and backward pumping efficiency is improved substantially.

Description

technical field [0001] The invention relates to a water conservancy engineering facility, which is a structure of a low-lift two-way pumping vertical pump device, and belongs to the technical field of water conservancy engineering. Background technique [0002] With economic construction and social development, there are more and more urban flood control and drainage combined with low-lift irrigation and drainage projects, which put forward new requirements for two-way pumping stations. Usually, the head of this type of pumping station is very low, often operating in the range of low head of about 1.0 m. There are basically three types of existing pumping stations of this type: horizontal S-shaped, vertical shaft and bulb tubular pump devices, all of which are equipped with impellers that can run forward and reverse. Due to the particularity of the two-way water inlet and outlet structures, the efficiency of forward and reverse operation of these pump stations is relatively...
