Description
Technical field
The utility model relates to a kind of open type intake pool rear wall partition wall and to disappear whirlpool device, belongs to open type intake pool design field.
Background technology
In open type intake pool basic flow pattern, some current enters oviduct from the rear portion of oviduct, therefore must leave certain space and back wall distance.Excessive or too small back wall distance all can have a strong impact on the flow-shape in intake pool, so rear wall place is the position easily producing vortex rope and backflow, in intake pool, the whirlpool whirlpool at rear wall place can affect the operation of water pump in various degree.For this reason, except taking in forebay to arrange except the rectification measure such as column or end bank, the generation that the method such as deflection cone, buoyant foam prevents rear wall backflow and whirlpool can also be set by the water surface in intake pool.But the method fundamentally can not solve rear wall water surface whirlpool problem.
Utility model content
The utility model is exactly for above-mentioned the deficiencies in the prior art, provide a kind of effectively can improve open type intake pool rear wall place fluidised form, promote the pump sump uniformity, prevent open type intake pool rear wall place refluxes and vortex rope occurs open type intake pool rear wall partition wall to disappear whirlpool device.
The technical solution of the utility model is, a kind of open type intake pool rear wall partition wall disappears whirlpool device, the suction water pipe, the oviduct that comprise intake pool, intake pool rear wall and be arranged in intake pool, it is characterized in that: between described intake pool rear wall and oviduct, be provided with partition wall, flush with the horn mouth of oviduct bottom partition wall, design water level in partition wall top and intake pool flushes, and the thickness of partition wall is 0.05-0.10m.
The width of described partition wall is the distance of horn mouth to intake pool rear wall of oviduct.
The material of described partition wall is concrete wall, steel plate or high strength glass fiber reinforced plastic.
On the connecting line of the horn mouth that described partition wall is arranged on oviduct closest to intake pool rear wall.
Described partition wall arranges and is fixed on intake pool rear wall, and partition wall is equal with the distance between the left wall of intake pool and the right wall of intake pool.
The utility model rational in infrastructure simple, manufacture easy, easy to use, pass through the utility model, between intake pool rear wall and oviduct, be provided with partition wall can significantly rectification to disappear whirlpool, block the position that backflow occurs at open type intake pool rear wall place, make left and right sides current enter oviduct along the partition wall of rear wall, effectively improve flow-shape, promote the flow velocity uniformity of oviduct entrance, water pump is made to obtain good flow condition, Boosting pumping station operational efficiency.
The water body of the water surface downward about 1/3, enter on rear side of oviduct oviduct, too small back wall distance will cause uneven fluidised form and larger oviduct water inlet loss, and it is unnecessary that excessive back wall distance is not only, but also add the degree of freedom of current in rear wall space.Adding partition wall at rear wall place can stop left and right two parts water body to exchange, and stop the generation of recirculating zone on a large scale, arrange bottom partition wall and flush with horn mouth, partition wall upper surface and the water surface flush, and width is the distance of horn mouth to rear wall, and thickness is 0.05-0.10m.
When water pump operation, part current enter oviduct from front, part current enter from both sides, some then walks around both sides, oviduct is entered from rear wall, this part current easily bumps against at rear wall place, produce recirculating zone, set up rear wall partition wall and effectively can block the abnormal fluidised form that rear wall place left and right sides current hit convolution mutually, the current near partition wall are made to enter oviduct rear portion along partition wall uniform, smooth, and not easily cause one side to intake, make flow-shape overall distribution near oviduct even, symmetry stably enters suction water pipe.
Advantage of the present utility model:
Open type intake pool rear wall partition wall significantly can improve the fluidised form at rear wall place, effective generation and the elimination rear wall whirlpool stoping recirculating zone.And make the flow velocity uniformity in oviduct be tending towards even, effectively prevent generation and the unidirectional water inflow of whirlpool.This practicality new patent is applied to pumping plant construction and upgrading, and can effectively disappear whirlpool rectification, improves the cavitation performance of pump installation, Boosting pumping station operational efficiency, and easy construction.Along with the construction of South-to-North Water Transfer Project and the enforcement of national small and medium-sized pumping station technological transformation, the intake pool fluidised form of up to a hundred pumping plants is had to need to improve altogether, by application and the enforcement of the utility model technology, larger economic benefit and social benefit can be obtained, be applicable to designing institute design adopt and in engineered middle enforcement.
