Description
Technical field
The utility model relates to the technical field of pumping plant rectification, particularly relates to a kind of water inlet increaser structure.
Background technique
Pumping plant water inlet buildings or structures mainly refer to pumping plant water inlet box culvert (water intake conduit), water inlet increaser and and pump house between forebay and runner, its effect ensures evenly directly to supply water to the water inlet that pump house is all, prevent band eddy water from flowing to into water pump, the normal operation of feed water pump brings adverse influence.
But, in Practical Project, pumping plant water inlet box culvert and water inlet increaser, certain angle is there is between water inlet increaser and pump house main body water (flow) direction, cause current with larger inertia, often occur that in water inlet buildings or structures, main flow has little time fully to the phenomenon of whole water inlet section diffusion, current are in water inlet box culvert (water intake conduit), there are current in water inlet increaser to turn, whirlpool district is there is in main flow one or both sides, current are oblique enters runner, the water inlet flow channel particularly kept to the side, current rush at sidewall along going out flow path direction, comparatively strong sticking wall flow is formed in increaser, and the comparatively high current defined in pump house along outer wall moves, cause fluidised form unstable, and generally can form whirlpool funnel, make water pump suction pipe become a mandarin uneven even occur water pump suction pipe suck air, pump efficiency is caused to reduce and even cause water pump to vibrate, affect water pump normal, efficiently, safe operation.Large pumping station due to pump house forebay and water inlet pipe culvert longer, water inlet pool diffusion cone angle is large, and flow-shape problem is more outstanding.
Therefore, the applicant is devoted to develop a kind of increaser structure and pumping plant method for rectifying of intaking, and solves pumping plant in water inlet process, the unstable and easy problem forming whirlpool funnel of the fluidised form that current turning exists.
Model utility content
Because the above-mentioned deficiency of prior art, the utility model proposes a kind of increaser structure of intaking, solve pumping plant in water inlet process, the unstable and easy problem forming whirlpool funnel of the fluidised form that current turning exists.
For achieving the above object, the utility model provides a kind of water inlet increaser structure, comprise a water inlet increaser, described water inlet increaser is bending pipeline, the inner bottom surface of described water inlet increaser is set to plane of inclination, and described plane of inclination tilts by inside lateral, and current are when by described water inlet increaser, due to turn formed centrifugal force will by described inclination surface current provide centripetal force offset, uniform fluid flow is distributed on described plane of inclination.
Preferably, the cross section of described water inlet increaser is rectangle.
Preferably, the outside of the inner bottom surface of described water inlet increaser is higher than inner side at least 1000mm.
Preferably, the water intake width of described water inlet increaser is 3000mm to 4000mm, is highly 2000mm to 3000mm; The water outlet width of described water inlet increaser is 7500mm to 8500mm, is highly 2000mm to 3000mm.
Preferably, the water intake width of described water inlet increaser is 3500mm, is highly 2400mm; The water outlet width of described water inlet increaser is 8100mm, is highly 2400mm.
The beneficial effects of the utility model are as follows:
The present inventor is found by further investigation, pumping plant is in water inlet process, the main flow that current occur in the water inlet increaser at turning there will be whirlpool district along one or both sides, the problems such as sticking wall flow, so have developed water inlet increaser structure of the present utility model, by using for reference elevated ramp and the cant of expressway Turning regions to provide the principle of centripetal force, improve existing water inlet increaser structure, the cant of water inlet increaser inner bottom plate is formed plane of inclination, the centripetal force that the reasonable increase of outside height provides makes current be uniformly distributed in water inlet increaser, and main flow is close or be positioned at central position, this measure serves the effect increasing flow transverse gradients, the flow-shape and the flow velocity that make to enter pump house forebay are more even in increaser, increase the lateral diffusion of flowing, thus, current flow velocity and fluidised form in pump house are uniformly distributed, ensure the good hydraulic performance of pumping plant.
Pumping plant method for rectifying of the present utility model guides uniform fluid flow, reposefully to whole water intaking leading edge diffusion by utilizing new water inlet increaser structure in conjunction with suitable engineering measure, engineering measure structure is simple, economical, and effectively can improve pumping plant dispersion of flow state, current are uniformly distributed in Forebay of Pumping Station.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
