Cause water flow stability poor.The main reason is that the flow field vegetarian at the interior Pump Suction mouth of a river of water tank (pond) is random, velocity flow profile is not
Uniformly, vortex is generated, and closer to vortex core, flow velocity is bigger, and static pressure is smaller, and the tolerance dissolved in water is also bigger, by
Recess in vortex core area increases air inlet, reduces pump intake water inlet sectional area, leads to the water in pipeline
Instability of flow, thus the flowmeter poor repeatability examined and determine, measurement error is larger, while vortex makes water pump generate cavitation, reduces
The runnability of water pump.
Existing technology is to make partition in water tank (pond) to eliminate vortex.But pump intake flow field stablizing effect is not
Obviously, and project cost is relatively high.
Utility model content
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of anti-whirlpool of pump intake is whole
Device is flowed, applied fluid mechanics is theoretical, analyzes the flow field of pump intake, eliminates the vortex of water inlet region, improves
Water flow stability, and make simply, price is low, is convenient for practical engineering application.
To achieve the above objectives, the technical scheme adopted by the utility model is that:
A kind of anti-whirlpool fairing of pump intake, is made of oviduct 1 and arc rectifier 2；The oviduct 1 exports
It is connected with arc rectifier 2,1 import of oviduct is connected with water feeding of water pump nozzle 3, for reducing the flow velocity of pump intake；Institute
It states 2 surface of arc rectifier and is designed as honeycomb, for dispersing energy, flow field adjusting and the reduction flow resistance of vortex.
On the basis of above scheme, 1 inlet diameter of oviduct is D, and 1 outlet diameter of oviduct is D1, oviduct 1
Outlet diameter D1 is 1.5 times of inlet diameter D.
On the basis of above scheme, the height H of the oviduct 1 equal with 1 inlet diameter of oviduct is D.
On the basis of above scheme, the diameter that the arc rectifier 2 exports connected end with oviduct 1 is D1, arc
The radian diameter of rectifier 2 is 2.5D.
On the basis of above scheme, the honeycomb is circle, diameter 8mm.
On the basis of above scheme, the anti-whirlpool fairing of pump intake is set in water tank 4, the water feeding of water pump
The anti-whirlpool fairing least significant end of mouth is 1.0D1~1.25D1 away from 4 floor height of water tank.
Pump intake and loud-speaker pipe 1 and arc rectifier 2 are combined together by the device, to meet water flow stability
Requirement.The distance between 1 minimum point of oviduct and 4 bottom plate of water tank are at least 1 outlet diameter D1 of oviduct, and oviduct 1 reduces
The flow velocity of water feeding of water pump nozzle 3, reduces the energy of vortex, and arc rectifier 2 has dispersed the energy of vortex and had preferable
Effect is adjusted in flow field, while reducing water flow to the active force of arc rectifier 2, enables the work reliably and with long-term of arc rectifier 2
Make.
The utility model has the beneficial effects that structure it is simple, it is at low cost, disappear that whirlpool and rectification effect are good, are easily installed and practical
Engineer application.After water feeding of water pump nozzle installs the utility model, flow field is stablized, and discharge stability is improved, and does not install this
Discharge stability is 0.7% before utility model, and installation the utility model disappears after the fairing of whirlpool, discharge stability 0.15%.
