Abstract

The invention relates to a novel pumping station water pump beam anti-vortex device and method, belonging to the technical fields of hydraulic engineering and municipal engineering. The novel pumping station water pump beam anti-vortex device comprises a water pump beam arranged in a water inlet tank. The novel pumping station water pump beam anti-vortex device is characterized in that the water pump beam is composed of a front water pump beam and a back water pump beam which are respectively arranged on both sides of a water outlet bent pipe in the water inlet tank; the front water pump beam is faced with the water inlet side of the water inlet tank; the upstream face of the front water pump beam is a streamlined section connected with double semicircular arcs; the upstream side of the front water pump beam is streamlined without rectangular edges; the cross section of the back water pump beam is a semicircular arc; and the side face of the back water pump beam adjacent to the water inlet tank is cambered. The novel water pump beam can effectively improve the flow state in the water inlet tank, reduces the occurrence of the reflux on the back wall of the water inlet tank and performs a flow regulation function. Meanwhile, the device can reduce the occurrence of the vortex around the water pump beam, thereby avoiding forming the vortex strip. The device and method are used for constructing and reconstructing a pumping station, can effectively enhance the operating efficiency of the pumping station, and improve the cavitation property of the pump unit.

Description

technical field [0001] The invention relates to a novel anti-vortex device and method for a water pump beam of a pumping station, and belongs to the technical fields of water conservancy engineering and municipal engineering. Background technique [0002] The quality of the flow state in the inlet tank of the pump station is directly related to the operating state of the unit. The disordered flow state in the inlet tank will significantly reduce the energy performance and cavitation performance of the pump, and may also cause vibration of the pump unit. In the specific engineering design, in order to facilitate the installation and maintenance of equipment, some structures are often added to the water inlet pool. Common forms of structures include: water pump beams, maintenance platforms and parapets. After these structures are set up, they will affect the flow state of the water inlet pool and the hydraulic performance of the bell mouth outlet of the water pump. Studies h...
