The nowed forming of fluid and analysis:

The nowed forming of fluid is divided into two kinds of grown forms of laminar flow and turbulent flow (turbulent flow).

Laminar flow: fluid layering flows, and only makees to slide relatively between adjacent two layers fluid, lateral between fluid layer to mix.

Turbulent flow: when fluid flow rate is more than a certain numerical value, fluid no longer keeps laminar flow, and may transport to all directions It is dynamic, have the component velocity perpendicular to tube axial direction, each fluid layer will be got mixed up, and be possible to be vortexed, this flow regime Turbulent flow.

Fluid is in laminar flow or turbulence state is generally determined with Reynolds number.Reynolds number is small, it is meant that fluid each matter when flowing In the highest flight, each particle of fluid is parallel to pipeline inner wall and flows regularly viscous force between point, is in laminar flow state.Thunder Promise number is big, it is meant that in the highest flight, fluid is in Turbulence Flow state to inertia force, and general pipeline reynolds number Re < 2000 is laminar flow State, Re > 4000 are turbulent condition, and Re=2000~4000 are transition state.Under different flow regimes, the fortune of fluid The distribution etc. of dynamic rule flow velocity is all different, thus the mean flow rate of fluids within pipes and the ratio of maximum flow rate are also not With.Therefore the size of Reynolds number determines the flow behavior of viscous fluid.

The calculation formula of Reynolds number:

Re=ρ vL/ μ

In formula:

Re is Reynolds number；ρ is fluid density；μ is fluid viscosity；V is the characteristic velocity in flow field；L is that the feature in flow field is long Degree.

The beneficial effects of adopting the technical scheme are that

Purifying cutting fluid device filtering tank:

Since cutting fluid can bring the metal fillings of Tool in Cutting workpiece wherein into cyclic process, making can not in cutting fluid What is avoided contains metal fillings, therefore this decontamination cycle technique passes through purifying cutting fluid filtering tank to the biggish metal fillings of volume first It is filtered.

In decontamination cycle technological work, if filtering tank upper cover is opened, diaphragm pump will suck air, cutting fluid is forced to be stopped It only recycles, even if being again switched off filtering tank upper cover, because air-resistance phenomenon can not be such that oil extraction motor works normally, therefore, is replacing It needs to shut down when filter screen, it is smaller to replace influence caused by the time shorter operation on equipment of filter screen, while to ensure to seal Reliability, to avoid sucking air.Purifying cutting fluid device filtering tank is when being taken out filtering net operation, by screwing part Lid and tank mouth are unclamped a relatively-movable gap out, carry out the behaviour of so of short duration time by structure as long as rotation knob After work, by horizontally rotating part-structure, crossbeam is rotated horizontally, lid can be removed rapidly and take out filter screen；It replaced When being sealed after strainer to tank mouth, lid is moved to above tank mouth rapidly by rotating horizontally crossbeam, lid can be restored to Gap when body and tank mouth are unclamped, by screwing part-structure, as long as rotation knob, carries out inverse operation, tank mouth can be completed Sealing.Removing and acting in place in time rapidly to lid, is exerted a force big and can be self-locking feature using helicitic texture, completion lid Required pressure is sealed between tank mouth and keeps the sealed pressure, while helicitic texture being exerted a force by sliding pressing structure When spinning movement neutralizing fall, so that filter screen inside purifying cutting fluid device filtering tank be allow to take out replacement process in short-term Interior completion.In this technique, the filter screen replacement of filtering tank, which has, operates convenient, reliable in action, using it is safe the features such as.

Although purifying cutting fluid device filtering tank has certain filtration to the metal fillings in cutting fluid, in view of filter screen The specification in hole is limited, and is had smaller particle and is entered the circulatory system, although smaller particle will not cause the use of cutting fluid It influences, but the circulation power source as cutting fluid, the selection of pump is still required, therefore the present invention uses diaphragm pump with true The reliability of its service life and work is protected, but diaphragm pump has biggish pulsation to rush due to its own working principle in its outlet Hitting property, forms turbulent flow, and splashes when being pumped into cutting fluid-waste oil separate tank impact cutting fluid and waste oil separation.

Liquid turbulence-laminar flow conversion equipment:

Turbulent flow is since fluid flow rate is fast, and it is larger to contain kinetic energy, makes the moving particle of internal fluid not only along pipe axis The linear motion in direction mixes with one another between particle also with lateral disturbance, the flow regime of vortex phenomenon occurs.The present apparatus To the fluid for being in turbulence state, by taking energy dissipating, damping, the measure for forcing water conservancy diversion, restrict shortest apart from interior as layer Stream mode.

The sectional area of present apparatus liquid outlet is the three times of inlet sectional area or more, consumes the energy of fluid, drop on the whole Low flow velocity v, each downward water conservancy diversion damping fin and each upward water conservancy diversion damping fin alternate intervals are arranged, and are parallel to the cross section of rectangular tube Setting.For fluid when by the inner cavity of rectangular tube, each damping fin generates damping energy dissipation effect to fluid, in rectangular tube The fluid of chamber uniformly carries out energy consumption on the whole, avoids fluid flow state due to local resistance excessive generation line phenomenon Generate interference.

The cavity length of rectangular tube is the three times of its height or more, meets fluid by turbulent flow and switchs to laminar flow to duct length It is required that.

On the upper end edge and rectangular tube of each downward water conservancy diversion damping fin cavity wall connect, the left end edge of each downward water conservancy diversion damping fin and Right end edge is connect with the left side wall top of rectangular tube and right side wall top respectively；The lower end edge and rectangle of each upward water conservancy diversion damping fin Manage lower cavity wall connection, the left end edge of each upward water conservancy diversion damping fin and right end along respectively with the left side wall lower part of rectangular tube and right side wall Lower part connection；The lower end edge of each downward water conservancy diversion damping fin and the inner cavity lower part of rectangular tube form and are forced up flow-guiding mouth, each upward The upper end edge of water conservancy diversion damping fin and the inner cavity top of rectangular tube form and are forced downwardly flow-guiding mouth.Make fluid in rectangle tube cavity in S The flowing of type longest path, in the case where rectangle length of tube is constant, farthest extends the flow distance of fluid, it may be assumed that increases The characteristic length L in flow field is added.

The fluid of the height value of the width value > rectangular tube intracavity section of rectangular tube intracavity section, same volume is entering square After shape tube cavity, thickness is opposite to be reduced, and the unordered fluid ability enhancing of each particle of internal fluid is restricted, to increase Reynolds number Re is switched to the critical value of turbulent flow by laminar flow.

Each downward water conservancy diversion damping fin, each upward water conservancy diversion damping fin are made of spring steel plate, and elasticity occurs when being impacted Deformation, slows down liquid impact flow.

In this technique, liquid turbulence-laminar flow conversion equipment comprehensively considers the various factors to form turbulent flow, using relevant art The various factors for forming turbulent flow is dissolved with relatively small volume (length), fluid is made to be converted into layer by turbulence state by means Stream mode.So that cutting fluid is gently entered cutting fluid-waste oil separate tank, avoids making liquid in pond from generating fluctuation, make at its as far as possible In stationary state, so that cutting fluid and waste oil keep good isolating environment.

Cutting fluid waste oil remove device:

Oil liquid separating opening in cutting fluid waste oil remove device can will swim in liquid table when in running order Waste oil (oil slick layer) the importing Oil Guide in face is intracavitary, the working condition of oil liquid separating opening are as follows: each notch bottom is horizontal along holding and is cutting On the interface for considering liquid and waste oil to be worth doing.The convex portion formed between each notch of oil liquid separating opening is swum on liquid level, protrusion Portion outboard wall barrier liquid enters Oil Guide chamber, so that liquid level and liquid level actual height at convex portion lateral wall be made to protect Almost the same difference in height with bottom formation equalization at of each notch is held, is made uniform along the liquid level of top positioned at each notch bottom Into Oil Guide chamber；Each notch bottom is horizontal along holding and on the interface of cuttings liquid and waste oil, that is, it is (floating that each notch is located at waste oil Oil reservoir) in, so that it is intracavitary so that waste oil (oil slick layer) is flowed into Oil Guide, then it is discharged by the oil outlet of Oil Guide chamber lower end through oil exit pipe, from And reaches cutting fluid waste oil and remove purpose.Since waste oil (oil slick layer) density is far below the density of cutting fluid, with waste oil The growth of clearance time, waste oil (oil slick layer) thickness are gradually reduced, and catch of used oil slightly rises, and each notch is relative to waste oil (oil slick layer) locating height gradually can be moved up slightly, to prevent cutting fluid intracavitary by each notch inflow Oil Guide, ensured useless Oil removes the stability and reliability of work.

Catch of used oil is equipped with buoyancy and generates chamber, counterweight holding tray and counterweight.Buoyancy generates chamber and generates to catch of used oil Buoyancy, according to cuttings liquid, waste oil density and swim in waste oil (oil slick layer) thickness on cutting fluid surface, by adjusting counterweight, The weight for adjusting catch of used oil swims in the convex portion between each notch for forming oil liquid separating opening on liquid level, respectively Notch bottom is along the operating condition being maintained on the interface of cuttings liquid and waste oil.

The vertical guide type shoe of catch of used oil includes the catch of used oil vertical guide of pedestal He the side of being set on the base, bottom Seat be used to support in cutting fluid trench bottom, and make catch of used oil vertical guide keep plumbness, catch of used oil be equipped with The bottom edge of the pilot hole of catch of used oil vertical guide slide fit connection, each notch is flat edge, and is in same level height, can be protected It holds catch of used oil and is constantly in working condition straight up, to make each notch bottom along holding level, to ensure oil liquid point It is in running order from mouth.

In this technique, cutting fluid waste oil remove device has waste oil elimination efficiency high, the operation is stable, reliable, can continuously not The features such as being interrupted unattended automatic work.

Cutting fluid-waste oil separate tank liquid outlet produces ozoniferous outlet by three-way connection and ozone generator, Sterilization processing is carried out to the cutting fluid that purification separation goes out, cutting fluid is can effectively prevent and goes bad, to extend the use longevity of cutting fluid Life.

Therefore, purifying cutting fluid circulation technology can cutting fluid to numerous stock-removing machines used in enterprise simultaneously into The good purification of row and sterilization processing reduce the waste of cutting fluid to extend the service life of cutting fluid.Reducing enterprise's production While cost, the pollution to environment is decreased.
