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 fills
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 separates out.Whirlpool is all produced at flow inlet.Whirlpool is ubiquitous, is a kind of extremely complex fluid forms of motion,
The harm of water inlet whirlpool: 1, increase resistance to water-flow, reduce discharge area, reduce inflow, reduce discharge coefficient, air-breathing occurs
During whirlpool, conveyance capacity can be made to reduce 80%.2, aggravation flow fluctuation produces strong fluctuation pressure, causes unit or works to shake
Dynamic.3, reducing unit efficiency, strong air-breathing whirlpool can reduce the efficiency of unit 80%.4, volume inhales floating thing blocking or damage sets
Standby etc..
Data shows, above water inlet, the water surface is all it may happen that vortex, a kind of quasi-stability being to have large scale
Water surface vortex, a kind of be the water surface vortex that occurs at random of little yardstick from the point of view of engineering values, 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 is maximum to Effects on Engineering, in order to avoid
The various problems that whirlpool causes, sometimes have to carry out under relatively low discharge.Law is cut down, in whirlpool according to Biot one sand
The heart, its speed is the highest, and static pressure is the lowest, thus the air penetrated into is the most the more, not only reduces the fullness degree of pipeline, and spiral is transported
Dynamic stroke and the friction loss of adding, whirlpool existence turbulent flow aggravates, and main flow and whirlpool district constantly have mass-energy to exchange, matter
Between point, frictional impact consumes a large amount of mechanical energy.
Viscosity is to produce the basic factor of whirlpool, and the flow field with current gradient makes viscosity play effect thus forms 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 reduces as far as possible, destroys unfavorable flow-shape and can effectively prevent the generation of air-breathing whirlpool, and diplopore water inlet is significantly better than single hole
Water inlet, is that whirlpool easily sends out region in the range of 30 ° above water inlet.
Pump intake exists prewhirls, and has eddy current in suction tube equally.The mixing eddy current having rotation in suction tube before pump, comes
Coming from the rotation of impeller of pump, it is passed to suction tube in pump by liquid viscosity.Its intensity is with the increasing from pump intake distance
Adding and weaken, vortex, in the range of 7 times from pump intake calibers, directly influences pump lift and flow.The whirlpool of pump discharge
Whirlpool enters downstream line normal pipe flow district, and the whirlpool of water inlet can cause stronger pulsating motion simultaneously, the work shape of feed pump
State is brought unfavorable, increases vibration and noise.For gas in normal pipe flow and the mixed flow of helical swirl, 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 and cost-reducing, it is generally desirable that
Pipeline fluid is under conditions of certain runner form, wall roughness and current state are certain, it is possible to reduce pipeline on-way resistance
Loss, increases the purpose of flow.But due to the air-breathing vortex of the water inlet water surface, cause the air entering in water to increase, another
Aspect, dissolves in the fullness degree that the air in water reduces in pipe, it is impossible to satisfied flowing reduces flow, and on the other hand, vortex makes
Current be not that straight line is advanced in pipe, but flow along hand of helix, virtually add the stroke (actual (tube) length than pipeline
Degree is long) thus add linear loss.Reduce in addition to pipeline itself (such as inner surface etc.) is improved and dissolve in water
Gas, improves the flowing quality of water body in pipeline, is only minimizing drag losses, increase the principal element of flow.
