Bernoulli principle be before hydromechanical continuum theory establishing equation, it is substantially former used by hydraulics
Reason, its essence is the conservation of mechanical energy of fluid, it may be assumed that kinetic energy+gravitional force+pressure potential=constant, bernoulli principle often by
It is expressed as p+1/2 ρ v2+ ρ gh=C, this formula, that is, Bernoulli equation.P is the pressure of certain point in fluid in formula, and v should for fluid
The flow velocity of point, ρ is fluid density, and g is acceleration of gravity, and h is height where the point, and C is a constant.Such as Fig. 1 and Fig. 3 institute
Show, Bernoulli equation can also be expressed as p1+1/2ρv1 2+ρgh1=p2+1/2ρv2 2+ρgh2.It can be seen that when contour flowing,
Flow velocity is big, and pressure is with regard to small.But traditional in Fluid Mechanics research, the adhesion in fluid is limited only to flow to the research of fluid
Dynamic relationship, it is few to flow rate effect research, and also unclear how by depressurizing to influence flow velocity.Such as in siphonic system,
People only study emphatically influence of the space of fluid in the construction and pipeline of pipeline to flow velocity, do not study and how to depressurize to flow velocity
It works, after siphonic system setting, flow velocity and efficiency substantially constant.
And fluid be it is a kind of by any small shear action when, can all generate the substance of continuous modification.Real fluid is all
With viscosity, referred to as viscous fluid, caused by the viscosity of liquid is mainly fluid molecule cohesive force.Adhesive just becomes flow velocity
A kind of active force.
According to liquid 1) principle of isobaris surface: in gravitational field, in static, of the same race, continuous fluid, horizontal plane is isobaric
Face and 2) bernoulli principle, it is known that pressure lacks the big principle of flow velocity.Wherein, bernoulli principle: p+1/2 ρ v2+ ρ gh=C, namely
p1+1/2ρv1 2+ρgh1=p2+1/2ρv2 2+ρgh2.To the speed of certain point in fluid: V2(point)=2C-2p-2gH, and rainbow
Flow velocity: V=√ [(2gH)/(1+ ζ+λ L/d)] is inhaled, in formula: V-siphon pipe mean velocity in section；G-acceleration of gravity；H-rainbow
The acting head (height difference of the syphon mouth end water surface and the outlet end water surface) of suction pipe；ζ-siphon pipe coefficient of partial resistance；
λ-siphon pipe frictional resistant coefficient；D-siphon pipe internal diameter.From formula it is found that the flow velocity of siphon pipe 110 by p value shadow
It rings, is p (pressure) smaller, V (face) flow velocity is bigger.
Since the density of fluid to be conveyed and discharge Jie of pressure are both less than in discharge pipe 120 with density and pressure
Matter, when starting fluid conveying, discharge pipe 120 can cut off the adhesion of the fluid positioned at 110 inlet of siphon pipe, change and flow into
The pressure of fluid and control adhesion point in conveyance conduit, fluid flows into conveyance conduit around discharge pipe, lower in discharge pipe
The discharge medium of pressure can generate pressure difference to the fluid that flows into conveyance conduit, rapidly by the pressure reduction of fluid, thus, it releases
Pressure suffered by fluid is exactly preferably minimized by the effect of pressure pipe, and according to the negatively correlated relationship of above-mentioned pressure and flow velocity, stream
The pressure of body reduces, and can achieve the purpose quickly flowed, the low pressure strong medium when fluid flows into conveyance conduit, in discharge pipe
Shearing force (moment cutout) is generated to fluid (density than the discharge medium in discharge pipe is high), stiction force is cut off, to release
Maximum gravity is put, flow velocity is improved, improves flow, reduces energy consumption.
Present embodiment additionally provides a kind of pipeline fluid flow velocity speed increasing method, principle siphonic system 100 for example above
Principle it is identical, by adding the discharge pipe of a both ends open in the entrance close to the conveyance conduit for trandfer fluid, control
One end of discharge pipe is located in fluid and opposite with the entrance of conveyance conduit, and the other end is extend out to outside fluid, filling in discharge pipe
There is discharge medium, the density and pressure of the discharge medium are respectively less than the density and pressure of fluid to be conveyed, when flow velocity starts edge
When conveyance conduit flows, due to the presence of discharge pipe, the pressure of fluid can be reduced, improves flow velocity.
In one embodiment, the radial dimension that discharge pipe is located at the intracorporal one end of stream is less than the diameter of the entrance of conveyance conduit
To size.Preferably, it can control the end face for being located at the intracorporal one end of stream of discharge pipe equal with the end face of the entrance of conveyance conduit
Row, it is further preferred that controllable discharge pipe is located at the entrance coaxial line for flowing intracorporal one end and conveyance conduit, in order to flow
Velocity modulation section.
Further, in one embodiment, there is difference in height and/or pressure between the entrance and outlet of conveyance conduit
Difference, if conveyance conduit can be but be not limited to the siphon pipe of inverted U, fluid to be conveyed is conveyed using siphon mode.
In the present embodiment, when fluid to be conveyed is liquid, discharge medium is preferably natural air, or
Density and pressure are less than the liquid of fluid to be conveyed and the liquid and fluid to be conveyed are immiscible；When fluid to be conveyed is
Gas, discharge medium are that density and pressure are respectively less than the density of fluid to be conveyed and the gas of pressure.
Specifically, the pipeline fluid flow velocity speed increasing method can be by adjusting the caliber for being located at the intracorporal one end of stream of discharge pipe
And/or the relative position of the entrance of the end and conveyance conduit adjusts the speedup amplitude of flow velocity.Specific regulative mode can root
Flexible modulation is carried out according to the speedup situation of specific required flow velocity.
The present invention has found after study, test is compared using Fig. 1 and siphon mode shown in Fig. 2, due to increasing in Fig. 2
Discharge pipe 120 is added, flow obviously increases, and flows per unit time increase can be to 30% or more.
