Abstract

The invention relates to an inner-cylinder axial-flow integrated pre-fabricated pumping station. The pumping station comprises a cylinder, a submersible axial-flow type sewage pump, an air discharge pipe and a control system. The cylinder is provided with the air discharge pipe. The submersible axial-flow sewage pump is installed in the middle, or the lower part or the middle-lower part of a shaft. The lower part of the shaft is coaxially installed in the cylinder. The lower part of the shaft communicates with the lower part of the cylinder. The side wall of the middle of the cylinder is provided with a water inlet. The upper part of the shaft is connected with a lower opening of a three-way connector. The side opening of the three-way connector is connected with a water outlet stretching out of the cylinder. The water outlet is higher than the water inlet. An upper opening of the three-way connector is provided with a connector sealing cover. One end of the connector sealing cover is movably hinged and the other end thereof is snapped onto and locked with the upper opening of the three-way connector. The upper opening of the cylinder is provided with a well lid with a safety grille. One end of the well lid is movably hinged and the other end thereof is snapped onto and locked with the upper opening of the cylinder. A maintenance platform is arranged in the cylinder. The height position of the maintenance platform is arranged between a water outlet and the connector sealing cover. An upper ladder is connected between the upper opening of the cylinder and the maintenance platform. The maintenance platform is downwardly connected with a pressure sensor and a lower ladder, both of which stretch into an inner cavity of the cylinder. The submersible axial-flow sewage pump and the pressure sensor are connected with the control system.

Description

technical field [0001] The invention relates to a pumping station, in particular to an inner tube axial flow integrated prefabricated pumping station. Background technique [0002] At present, a large number of traditional concrete fixed pumping stations are used by integrated pumping stations due to many shortcomings such as large project investment; high operation and maintenance costs; replace. However, the existing integrated pumping station sucks the sewage in the cylinder body of the pumping station through the centrifugal sewage pump. With the continuous promotion and application of integrated pumping stations, the demand for integrated pumping stations in terms of function and scale is increasing. With the problems of bottom siltation, increased floor space, and rising investment costs, its advantages are getting smaller and smaller. Contents of the invention [0003] The invention provides an axial-flow integrated prefabricated pump station with an inner cylinde...
