Description

A double-barrel integrated pumping station

technical field

The invention relates to a double-tube integrated pumping station, which belongs to the fields of water supply and drainage engineering and water conservancy engineering.

Background technique

With the continuous expansion of the city scale, the discharge of urban sewage is also increasing. The integrated pump station plays an increasingly important role in the process of urban sewage collection and centralized treatment. The integrated pumping station is mainly composed of glass fiber reinforced plastic forming cylinder, submersible sewage pump, maintenance platform, escalator, water inlet pipe, water outlet pipe, automatic coupling device, automatic control system, etc. It is mainly used to collect and discharge sewage and wastewater in residential quarters, restaurants, schools, factories, military barracks and other public places, and is mainly installed in buried or semi-buried.

At present, the cylinder body of the integrated pump station on the market adopts a single cylinder structure, and the bottom of the cylinder body is fixed, resulting in a certain suspended height of the water pump bell mouth. The value of the suspension height has a significant impact on the flow state near the bell mouth, and a suitable suspension height will make the water flow into the bell mouth smoothly and evenly. When the suspended height is small, the flow state of the water entering the bell mouth is very poor, resulting in a large hydraulic loss, and it is easy to generate vortex and cause cavitation of the water pump. When the suspended height is large, the water flow velocity at the bottom plate is small, and the water flow cannot be fully absorbed. Sewage contains a lot of sludge and other impurities, which makes it easy to accumulate sludge and garbage at the bottom of the pumping station, which not only affects the performance of the pumping station but also produces odors. It is very inconvenient to clean up and waste a lot of manpower and material resources. Maintenance and Cleanup costs are high. Authorized invention patent 201120088061X adopts a well-type pumping station that can generate pre-swirling water flow. The technical principle is that the sewage at the bottom of the sewage pool flows into the pre-swirling basin along the inner ditch of the pre-swirling basin, and forms a flow in the pre-swirling basin in the direction of rotation of the pump. The same water flow can effectively reduce the shutdown water level of the pump, and is beneficial to cleaning the sewage and sludge at the bottom of the sewage pool. However, due to the increased pre-rotation of the pump suction port, the rotation volume of the pump will increase, which will cause vibration and cavitation of the pump unit. Published invention patent 201420411033.0 installs rotating cleaning paddles, plasma air deodorizers and exhaust pipelines at the bottom of the pump station, and stirs at the bottom through the rotating cleaning paddles to prevent sludge accumulation and eliminate odors to achieve self-cleaning effects. However, the rotating motor will generate a lot of vibration when it is working, and it cannot achieve a timely and effective self-cleaning function.
