Prefabricated pump station and water flow stabilizing method suitable for prefabricated pump station

Abstract

The invention discloses a prefabricated pump station. The prefabricated pump station comprises a prefabricated barrel, and a water inlet and a water outlet are formed in the prefabricated barrel. A pump barrel is arranged in the prefabricated barrel, and a water pump is arranged on the bottom section of the pump barrel. The upper end of the pump barrel communicates with the water outlet. Water flow falls into the bottom of the prefabricated barrel through the water inlet, is drawn into the pump barrel through the water pump located at the bottom of the prefabricated barrel and flows out through the water outlet, and a flow equalizing separation plate is arranged at the lower end of the water inlet. The flow equalizing separation plate is fixedly arranged on the inner wall of the prefabricated barrel and converts single-direction input water of the water inlet into annular water flow, and the annular water flow evenly falls onto the bottom of the prefabricated barrel. It is avoided thatthe water flow fixedly flows in a single direction at high flowing speed or impacts on the pump barrel, and consequently water flow turbulence is avoided. In particular, existing direct-in water flowis changed into the annular water flow, the flow equalizing separation plate is located around the barrel, water is drained downwards through water drainage openings evenly formed in the flow equalizing separation plate, the water flow rushing into the water inlet do not impact on the barrel directly, and therefore input water is equivalently and evenly drained downwards.

Description

technical field

[0001] The invention relates to the field of prefabricated pumping stations, in particular to a prefabricated pumping station with high impact resistance and high stability. Background technique

[0002] Prefabricated pumping stations are widely used and are pre-integrated pumping stations, which play a key role in the construction of new cities and the transformation of old urban water systems, flood control and disaster reduction, and rural water conservancy. Traditional pumping stations require large investment, long construction period, and large floor area, which affect the beauty of the city and have a low degree of automation. The prefabricated pumping station has the advantages of small civil engineering workload, low cost, less manpower and material resources consumption, and can coordinate with the surrounding landscape at the same time. Prefabricated pumping stations have become the focus of domestic and foreign municipal engineering and water con...
