Description
Technical field
The present invention relates to water delivery device field, especially a kind of full-automatic gas-liquid displacement variable cross-section syphonic water flow is filled
Put.
Background technology
Dissolved gas 20L/m in void fraction about 2%, i.e. water in natural water body, can be with micro- when pressure drops to a certain value
Bubble form is separated out.Whirlpool is all produced at flow inlet.Whirlpool is ubiquitous, is a kind of extremely complex fluid motion form,
The harm of water inlet whirlpool：1st, increase resistance to water-flow, reduce discharge area, reduce inflow, reduce discharge coefficient, air-breathing occur
During whirlpool, conveyance capacity can be made to reduce 80%.2nd, aggravate flow fluctuation and produce strong fluctuation pressure, cause unit or works to shake
It is dynamic.3rd, unit efficiency is reduced, strong air-breathing whirlpool can reduce the efficiency of unit 80%.4th, volume is inhaled floating thing blocking or is damaged and sets
It is standby etc..
Data shows that the water surface all may be vortexed above water inlet, and a kind of is the quasi-stability with large scale
The water surface is vortexed, and a kind of is that the water surface that little yardstick occurs at random is vortexed from from the point of view of engineering values, and the vortex that water inlet is formed is generally divided into
Free Surface whirlpool, under water whirlpool and three kinds of spiral pipeline whirlpool, wherein Free Surface whirlpool are maximum to Effects on Engineering, in order to avoid
The various problems that whirlpool causes, sometimes have to be carried out under compared with low discharge.Law is cut down according to the sand of Biot one, the closer in whirlpool
The heart, its speed is higher, and static pressure is lower, and so as to the air for penetrating into just the more, not only reduces the fullness degree of pipeline, and spiral is transported
Dynamic to increased stroke and friction loss, there is turbulent flow aggravation in whirlpool, main flow constantly has mass-energy to exchange with whirlpool area, matter
Frictional impact consumes a large amount of mechanical energy between point.
Viscosity is to produce the basic factor of whirlpool, and the flow field with current gradient makes viscosity play effect so as to form whirlpool
Move in whirlpool.The formation of whirlpool is relevant with inlet velocity size and depth of immersion.Improve the body structure of water inlet, reduce water inlet
Flow velocity is reduced as far as possible, and destroying unfavorable flow-shape can effectively prevent the generation of air-breathing whirlpool, diplopore water inlet to be significantly better than single hole
Water inlet, is that whirlpool easily sends out region in the range of 30 ° of water inlet top.
Pump intake is present prewhirls, and equally has vortex in suction line.The mixing for having rotation before pump in suction line is vortexed, and comes
The rotation of impeller of pump is come from, it passes through liquid viscosity and is passed in suction line from pump.Its intensity is with the increasing with a distance from pump intake
Plus and weaken, vortex directly influences the lift and flow of pump in the range of 7 times from pump intake calibers.The whirlpool of pump discharge
Whirlpool enters downstream line normal pipe stream area, while the whirlpool of water inlet can cause stronger pulsating motion, the work shape of feed pump
State brings unfavorable, increases vibration and noise.For the mixed flow of gas and helical swirl in normal pipe stream, be affect flow and
Increase the principal element of the pressure loss.
In water process, water supply, pipe network and water conservancy irrigation, long distance delivery engineering, in order to energy-saving, it is generally desirable that
Pipeline fluid in certain runner form, wall roughness and current state it is certain under conditions of, pipeline on-way resistance can be reduced
Loss, increases the purpose of flow.But because the air-breathing of the water inlet water surface is vortexed, cause the air entered in water to increase, it is another
Aspect, dissolves in the fullness degree that the air in water is reduced in pipe, it is impossible to meets flowing and reduces flow, and on the other hand, vortex makes
Current be not in pipe straight line advance, but along hand of helix flowing, virtually increased stroke（Than the actual (tube) length of pipeline
Degree length）So as to increased linear loss.Except to pipeline itself（Such as inner surface）Reduce outside being improved and dissolve in water
Gas, improves the flowing quality of water body in pipeline, is only reduction drag losses, increases the principal element of flow.
