Description

A kind of closed intake pool Prevention and dissipation cone
Technical field
The utility model relates to a kind of Prevention and dissipation cone, particularly relates to a kind of closed intake pool Prevention and dissipation cone, belongs to closed intake pool design field.
Background technology
Both at home and abroad for the progress morning of open type intake pool, achievement is numerous, on this basis the research of box culvert-type water inlet flow channel is become to the main flow of research in recent years, but does not occur too many report for the research of closed intake pool.
Because water feeding of water pump pond arranges suction water pipe, make intake pool and suction water pipe internal flow state very complicated, often in intake pool occur surperficial vortex and attached wall vortex two kinds of vortexs, they are the key factors affecting pump installation stable operation.Wherein surperficial vortex can cause air intake, brings out cavitation and cavitation erosion, and attached wall vortex forms low-pressure area in vortex core, and easily produce cavitation vortex rope, this vortex rope can cause periodic vibration & noise, affects pump performance and life-span.
For improving pumping plant intake pool fluidised form, the rectification measure adopted at present has: end bank, dividing plate, water squeezing plate and diversion pier etc.But current rectification measure is difficult to eliminate the bad vortex rope of intake pool thoroughly.
Utility model content
The utility model is exactly for above-mentioned the deficiencies in the prior art, there is the problem of vortex for solving closed intake pool, providing a kind of and effectively can improve the bad fluidised form of pumping plant intake pool, improve efficiency of pumping station, eliminate original vortex and do not bring out the closed intake pool Prevention and dissipation cone of new recirculating zone or vortex.
The technical solution of the utility model is, a kind of closed intake pool Prevention and dissipation cone, comprise the Prevention and dissipation cone arranged in closed intake pool, it is characterized in that, described Prevention and dissipation cone is conical, conical Prevention and dissipation cone is arranged on immediately below the water pump loudspeaker mouth of pipe, Prevention and dissipation cone center line overlaps with water pump axis line, the height of Prevention and dissipation cone is water pump loudspeaker nozzle diameter 1/3 times, the conical bottom diameter of Prevention and dissipation cone and the distance of Prevention and dissipation cone center line to intake pool rear wall and the equal diameters of the water pump loudspeaker mouth of pipe.
Described Prevention and dissipation cone is made up of Steel material or concrete, is arranged on the closed intake pool base plate immediately below the water pump loudspeaker mouth of pipe.
Described Prevention and dissipation cone is shell structure, and the surrounding at the bottom of Prevention and dissipation cone is arranged on closed intake pool base plate by bolt.
Described Prevention and dissipation cone is concrete structure, and Prevention and dissipation cone and closed intake pool bottom slab concreting are integrally.
The utility model rational in infrastructure simple, manufacture easy, easy to use, know-why of the present utility model is:
Current can be domatic along the taper of Prevention and dissipation cone rule, smoothly enters the pump housing, effectively improve flow-shape and reduce hydraulic loss, guaranteeing flow rate of water flow uniform increments from the surrounding of cone.
Backwater district below the water pump loudspeaker mouth of pipe fill up by cone, the fluidised form of avoiding stagnant water and dynamic aqueous phase mutual friction to collide and cause is disorderly; Prevention and dissipation cone destroys original bad flow-shape, and current are reconfigured, and to reduce strength of vortex and to eliminate vortex rope, improves efficiency of pumping station.
Not only obviously can improve the bad fluidised form of current below the loudspeaker mouth of pipe by adding Prevention and dissipation cone at pumping plant intake pool, and the effect that reduction vortex strength of vortex even eliminates vortex can be played.Prevention and dissipation cone has drainage, current smoothly enter the pump housing along cone is domatic, Prevention and dissipation cone effectively fills the backwater district below oviduct, simultaneously to the region of original generation vortex, current are recombinated, destroy vortex, by rectified action, make the active cross-section flow velocity entering blade wheel chamber be tending towards even.This practicality new patent is applied to pumping plant construction and upgrading, improves efficiency of pumping station 3% to 10%, plays huge economic benefit.
