Description

A kind of inductosyn integral type buoy suitable for thick liquid level gauging
Technical field
The present invention relates to integral type buoys used in a kind of inductosyn for thick liquid level gauging, belong to Technology of instrument and meter field.
Background technique
Viscosity Viscosity is the degree of stickiness, is the premiere feature of material, also referred to as dynamic viscosity, viscous (stagnant) property system Number, coefficient of internal friction.The viscosity of different material is different, such as under room temperature (20 DEG C) and normal pressure, the viscosity of air is 0.018mPas, gasoline 0.65mPas, water are 1 mPas, olive oil 102MPas, castor oil 103 MPas, honey 104MPas, tar 106MPas, pitch 108 mPa·s。
ViscosityWhen being defined as fluid and bearing shear stress, shear stress and shearing strain the gradient change rate of position (shearing strain with) Ratio, formulation are as follows:
In formula:For shear stress,Component for velocity field in the direction x,For the direction coordinate vertical with x.
The higher substance of viscosity, than less easily flowing;And the lower substance of viscosity, it is easier to flow.Such as oil Viscosity is higher, therefore is not easy to flow;And water viscosity is lower, is not only easy flowing, when pouring, there is also spray, when oily just It is not in similar phenomenon.
Shear viscosity is the laminar shear of fluid between two plates.And the friction between fluid and moving boundary results in Fluid shearing, describe this intensity of performance is the viscosity of fluid.In general PARALLEL FLOW, shear stress is proportional to speed Gradient.Movement speed between the adjacent layer being parallel to each other is different, generates shearing.And the shear viscosity of fluid is description to shearing The resistivity of flowing.In the ideal case, it is defined as Ku Aite stream: being trapped in level board --- the fixed side in side with Constant speed horizontal movement --- a layer fluid.If the speed of top plate is sufficiently small, fluid particles will be parallel to it and flow, And their speed is changed linearly from the ν at 0 to top of bottom.Each laminar flow speed of fluid is faster than the next of it Layer, can generate the frictional force for resisting their relative motions between them.In particular, fluid will be in the opposite direction of movement of roof Apply a power, can also generate an equal big reversed power in bottom plate.Therefore an external force is needed to maintain top plate with constant Speed movement.The size of power F the distance between is proportional to the movement velocity u and area A of every block of plate, and is inversely proportional to two plates, i.e.,
In this formula, proportionality coefficientIt is the shear viscosity of fluid;Ratio be known as shear-deformable or shear velocity, be Perpendicular to the derivative of the speed upper fluid speed of plate.
Dynamic viscosity is density p of the shear viscosity μ divided by liquid, is usually indicated with Greek alphabet ν:
When the liquid level sensor of currently used buoy or floating ball measures liquid level in thick liquid, especially tar, In the liquid such as crude oil, because perhaps floating ball is mostly that sphere or cylindrical body measuring staff are passed through from buoy or floating ball axis to buoy, buoy Or there is one section of long and narrow cylinder-shaped overlapping region between floating ball and measuring staff.It is filled with thick liquid in this overlapping region, The relationship between measuring staff and buoy in this overlapping region is considered as two blocks of level boards, according to above-mentioned formula, the size of power F The distance between be proportional to the movement velocity u and area A of every block of plate, and be inversely proportional to two plates.And unfortunately, in existing design, In order to keep balancing, what measuring staff passed through is the central axes of buoy or floating ball, and the area A of measuring staff and buoy overlapping region is most Greatly, and for buoy or the accurate location of floating ball, the gap of buoy and measuring staff wants as small as possible, for inductosyn Speech, buoy and measuring staff closely measuring staff as far as possible, i.e. distance between two plates are intended to minimum.Existing floating ball design, is caused same In the liquid of viscosity, power F is intended to maximum.Result caused by practical application is exactly the decline of buoy reaction sensitivity, Bu Nengji The variation of Shi Fanying liquid level.More commonly finally floating ball is thoroughly glued on the measuring rod due to power F is excessive, liquid level sensor Thoroughly failure, integral replacing are time-consuming and laborious expensive.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention devises a kind of induction type biography suitable for thick liquid level gauging Sensor integral type buoy.
The integral type buoy be under three-dimensional Euclidean geometry space or under three-dimensional Lobachevski geometry space or Any entity under three-dimensional Riemannian space;The entity is homogeneous entity or cavity, includes m sky when being cavity in cavity Chamber, m are the natural number more than or equal to 1
The entity meets simultaneously:
There are hole, inductosyn measuring staffs to pass through from this hole for integral type buoy central part;
When integral type buoy is in static balance under floating state in a liquid, the volume that each section arranges liquid ensures integral type Buoy central axes keep vertical.
A kind of inductosyn integral type buoy suitable for thick liquid level gauging, in the integral type buoy Center portion divides hole edge to there is the protrusion stretched out to central axes, and raised quantity is i, and i is the natural number more than or equal to 2;
Each protrusion is provided with one block of hard magnetic material, and the hard magnetic material material is identical, and quality is identical, and shape is identical, and every piece hard The magnetic pole that magnetic material is directed toward central axes is identical, i.e., or all pole N is directed toward central axes or all pole S and is directed toward central axes;
From depression angle, for the central part hole of the integral type buoy in the projection of horizontal plane, shape is two-dimentional Europe Any closing obtained under geometric space or under two-dimentional Lobachevski geometry space or under two-dimentional Riemannian space in several is bent The figure that line surrounds.
A kind of inductosyn integral type buoy suitable for thick liquid level gauging, protrusion is in integral type buoy Arrangement mode on central part hole are as follows: aforementioned closed curve perimeter is made into i equal part, i is the quantity of protrusion, each protrusion position In in each equal segments;When the closed curve be center symmetric figure when, and i be even number when, then protrusion with two be one group It is arranged in a manner of central symmetry on curve, each pair of protrusion is opposite along central axes.
A kind of inductosyn integral type buoy suitable for thick liquid level gauging, the integral type buoy, material Matter is metal or plastics.
A kind of inductosyn integral type buoy suitable for thick liquid level gauging, the buoy, appearance coating Or spray or be electroplate with zinc, chromium, nickel, gold, palladium, rhodium, Ag-Sn, Ag-Pb, Ag-Cd, Ag-Sb, Ag-Pd, raw lacquer, cashew resin Paint, phenolic resin coating, epoxy-phenolic paint, epoxy coating, chlorinated polyvinyl chloride paints, asphalt caulk, furane resins paint, poly- amino first Acid esters paint, inorganic zinc rich paint, polyurethane paint, epoxide coal bituminous, three polyethylene, polytetrafluoroethylene PTFE, soluble polytetrafluoroethyl-ne Alkene PFA, perfluoroethylene-propylene FEP, polytrifluorochloroethylene PCTFE, polyvinylidene fluoride PVDF, modified polypropene GXPP, modification Polyolefin GXPO, polyvinylchloride, ultra-high molecular weight polyethylene UHMW-PE, minimum a kind of protective layer in glass reinforced plastic phenolic aldehyde FRP.
The integral type buoy is the entity being present in three-dimensional space, and form can be common bowl-shape, sphere, ellipse Sphere, cylindrical body, disk like, it is also possible to which there are non-circular curve or variable curvature curve in surface, it is impossible to exhaustive with single mathematical formula Its specific form is described.But under the inevitable space with three-dimensional Euclidean geometry of form or under three-dimensional non-euclidean geometry space certain The form of one entity fits like a glove.It is well known that non-euclidean geometry two branches into greatly Lobachevski geometry and Riemannian, such as Fruit buoy/floating ball form cannot be by three-dimensional Euclidean geometry spatial description, with three-dimensional Lobachevski geometry sky Between the form of a certain entity under lower or three-dimensional Riemannian space fit like a glove.
When the entity of the integral type buoy is a homogeneous solid, entire buoy/floating ball is by a kind of uniform material structure At.When the entity of the integral type buoy is a cavity or hollow body, show its at least one cavity, the quantity of cavity For natural number, from 1 to infinite more.Injection is gas, liquid, steam or is aerosol in cavity.When number of cavities approaches When infinite more, the corresponding common material of buoy/floating ball is foamed material, i.e., substance internal gasifier produces in material preparation process Anger bubble makes porous mass.When there are cavity, in order to easy to process, in most cases, buoy removes cavity portion It is exceptionally still homogeneous solid.In some special cases, the homogeneous solid in addition to cavity can be chimeric using unlike material Technique, such as the embedding copper of aluminium, the embedding aluminium of stainless steel, the embedding plastics of metal.
There are hole, inductosyn measuring staffs to pass through from this hole for integral type buoy central part, it is ensured that buoy/floating ball It moves along a straight line along sensor measuring staff direction, tracks liquid level.
When integral type buoy is in static balance under floating state in a liquid, the volume that each section arranges liquid ensures one Body formula buoy central axes keep vertical.According to the law of buoyancy/Archimedes principle, the object in stationary fluid is immersed by one Buoyancy, size are equal to the fluid weight that is arranged of the object, and direction vertically upward and passes through the centroid of arranged fluid.Herein Under state, only holding hole is also at honest state, and buoy/floating ball will not just generate between measuring staff unnecessary directly to rub It wipes, guarantees buoy/floating ball normally with liquid fluctuating.
There is the protrusion stretched out to central axes in the central part hole edge of the integral type buoy, raised quantity is i, I is the natural number more than or equal to 2.Gap between different protrusions and measuring staff, can be the same or different.Different protrusions and survey Overlapping area between bar, can be the same or different.By the way that this protrusion is arranged, so that buoy/floating ball central part hole The area of hole and measuring staff apart from nearest part is no longer the area of entire hole, but the coincidence face of measuring staff and convex portion Product, i.e., measuring staff substantially reduces with buoy/floating ball overlapping region area A, reduces viscous force F according to viscosity formula.Protrusion Quantity be that natural number more than or equal to 2 could really reduce measuring staff and buoy/floating ball overlapping region area A, if it is 1 reality Measuring staff and buoy/floating ball overlapping region area A are increased in matter, do not have the effect for reducing viscous force instead.
Each protrusion is provided with one block of hard magnetic material, and the hard magnetic material material is identical, and quality is identical, and shape is identical.This It is because for inductosyn or be to generate induced current or be electric pulse using motion conduct cutting magnetic line It is run on measuring staff inner conductor, alternating magnetic field induction makes material generate magnetostriction mechanical oscillation, requires to be arranged by Hard Magnetic material Expect the stationary magnetic field generated.In the present invention, hard magnetic material is placed in buoy/floating ball convex portion, in order to keep the magnetic line of force close Cloth needs to be arranged 2 pieces and 2 pieces or more of hard magnetic material.Hard magnetic material material is identical, and quality is identical, and identical shape is to make It is easy to process, and the static magnetic field for generating every block of hard magnetic material is as similar as possible, is convenient for sensor sensing.
The magnetic pole that every block of hard magnetic material is directed toward central axes is identical, i.e., or central axes or all are directed toward in all pole N It is directed toward central axes in the pole S.According to Faraday's electromagnetic induction law or the graceful effect of Wei De, to generate induced electromotive force or mechanical vibration Dynamic, magnetic field just must so be arranged.And due to principle of induction, the higher the better for density of line of magnetic force, if distance of reaction is not close enough to, Or the magnetic line of force is sparse, may cause that effect is faint, and weak output signal can not pick up or signal is submerged in background noise.Such as Fruit occur different magnetic poles be directed toward central axes the case where, will cause sensor can not normal induction, cisco unity malfunction.
The protrusion is the entity being present in three-dimensional space, and form can be class spherosome, class cylindrical body, class prism Body, class prismoid take turns dentation, it is also possible to which there are non-circular curve or variable curvature curve in surface, it is impossible to poor with single mathematical formula Its specific form is described to the greatest extent.But form certainty and three-dimensional Euclidean geometry space or three-dimensional Lobachevski geometry The form of a certain entity under space or under three-dimensional Riemannian space fits like a glove.
From depression angle, projection of the central part hole of the integral type buoy in horizontal plane, shape two Tie up any envelope under Euclidean geometry space or under two-dimentional Lobachevski geometry space or under two-dimentional Riemannian space The figure that closed curve surrounds.Because the shape of protrusion can be made class spherosome, class cylindrical body, class prism, class prismoid, wheel Dentation ... ... can not use its exhaustive form of single normal form, but hole is considered as a configuration and is projected in horizontal plane, Because hole inner peripheral surface is continuous, the projection figure that necessarily a closed curve surrounds on perspective plane, this closed curve, Under the inevitable space with two-dimentional Euclidean geometry or under two-dimentional Lobachevski geometry space or in two-dimentional Riemannian space Certain root closed curve be completely coincident.It is more than or equal to 2 to the recess inside figure that this figure has quantity certainly, each recessed Sunken is all the projection of respective protrusions.
On the other hand, if the protrusion of hole central part cut, and by hole be considered as a configuration and Horizontal plane projection projects the figure that a closed curve surrounds on necessarily perspective plane, this closed curve, inevitable and two dimension Certain root closing under Euclidean geometry space or under two-dimentional Lobachevski geometry space or in two-dimentional Riemannian space Curve is completely coincident.The figure that this curve surrounds, because eliminating protrusion, observation is got up just not because of raised bring figure Recess, thus it is simpler than the projection comprising protrusion, it can be more convenient for that the concrete shape of buoy is discussed in practical applications, be convenient for The location and shape of protrusion are described.
Arrangement mode of the protrusion on the central part hole of integral type buoy are as follows: aforementioned closed curve perimeter is made into i etc. Point, i is the quantity of protrusion, and each protrusion is located in each equal segments.Particularly, each protrusion is located at the center of equal segments.This It is in order to allow hard magnetic material to be evenly distributed on hole inner edge, so that magnetic field dense distribution as uniform as possible, such buoy/floating Ball and when measuring staff relative motion any position of measuring staff move or buoy/floating ball relative to original state under have occurred with Measuring staff is the rotation or deflection of axis, can obtain the uniform intensive magnetic field of a magnetic line of force.So that inductive signal is more clear Clear stabilization.
If the protrusion of hole central part cut, and hole is considered as a configuration and is thrown in horizontal plane Shadow projects the figure that a closed curve surrounds on necessarily perspective plane, this closed curve, inevitable and two-dimentional Euclid Certain root closed curve under geometric space or under two-dimentional Lobachevski geometry space or in two-dimentional Riemannian space is complete It is overlapped.The figure that this curve surrounds can be considered as the simplification version for the figure that closed curve described in leading portion surrounds.It equally can be with: will Closed curve perimeter described in this paragraph makees i equal part, and i is the quantity of protrusion, and each protrusion is located in each equal segments.Particularly, often A protrusion is located at the center of equal segments.The uniform intensive magnetic field of a magnetic line of force can be equally obtained, so that inductive signal is more clear Clear stabilization.
When the figure that the closed curve surrounds is center symmetric figure, and protrusion quantity i is even number, then protrusion is with two A to be one group and arranged in a manner of central symmetry on curve, each pair of protrusion is opposite along central axes.Centrosymmetric image is exactly by one A figure is after some 180 ° of rotation of point, if postrotational figure is overlapped with original figure, this figure claims For center symmetric figure, this point is symmetrical centre.Common centrosymmetric image has: line segment, rectangle, diamond shape, and square is put down Row quadrangle, circle, number of edges are the regular polygon etc. of even number.It can be seen that can find i in common centrosymmetric image and divide equally week It is long, and make two opposite protrusions along the position that central symmetry arranges.Experiments have shown that under such distribution along formed symmetrical Protrusion possesses better Distribution of Magnetic Field and inductive effects.
If the protrusion of hole central part cut, and hole is considered as a configuration and is thrown in horizontal plane Shadow projects the figure that a closed curve surrounds on necessarily perspective plane, this closed curve, inevitable and two-dimentional Euclid Certain root closed curve under geometric space or under two-dimentional Lobachevski geometry space or in two-dimentional Riemannian space is complete It is overlapped.When this figure is common centrosymmetric image: rectangle, diamond shape, square, parallelogram, number of edges is even number When regular polygon, and protrusion quantity i is even number, can by protrusion with two for one group, each protrusion centre symmetrical side Midpoint, arranged in a manner of central symmetry, each pair of protrusion is opposite along central axes.
The integral type buoy, material are metal or plastics.Floating ball/buoy will impregnate in a liquid, float in order to prevent Ball/buoy surface corrosion, prevents buoy/floating ball from chemically reacting with liquid, and in order to process convenience, floating ball/buoy Material is usually metal or plastics, and common material has stainless steel, aluminium alloy, polythene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS, ABS resin, polycarbonate, polyamide PA, polyformaldehyde POM, Noryl PPS.It is non-using other The material of metal, non-plastic, such as ceramics and glass, buoy/floating ball are difficult to process and modify, and buoy/floating ball specific gravity is also bad Setting and modifying does not have a possibility that actual production.
The buoy, appearance coating spraying or be electroplate with zinc, chromium, nickel, gold, palladium, rhodium, Ag-Sn, Ag-Pb, Ag-Cd, Ag-Sb, Ag-Pd, raw lacquer, urushiol resin paint, phenolic resin coating, epoxy-phenolic paint, epoxy coating, chlorinated polyvinyl chloride paints, drip Green paint, furane resins paint, polyurethanes paint, inorganic zinc rich paint, polyurethane paint, epoxide coal bituminous, three polyethylene, polytetrafluoro Ethylene PTFE, soluble poly tetrafluoroethene PFA, perfluoroethylene-propylene FEP, polytrifluorochloroethylene PCTFE, polyvinylidene fluoride PVDF, modified polypropene GXPP, improved polyalkene GXPO, polyvinylchloride, ultra-high molecular weight polyethylene UHMW-PE, glass reinforced plastic Minimum a kind of protective layer in phenolic aldehyde FRP.This is because depending merely on buoy/floating ball in certain acid, alkalinity, corrosive liquids Material is insufficiently resistant to the erosion of liquid, it is necessary to be coated with the common oxidized layer such as zinc chrome nickel or gold-palladium rhodium on buoy/floating ball surface Equal noble metals or composite metal.The coatings such as traditional raw lacquer, epoxy resin, phenolic resin are applied, can also be played to floating The good protecting effect of mark/floating ball.With flourishing for fluorination work, polytetrafluoroethylene PTFE, soluble poly tetrafluoroethene These novel anticorrosion coatings of PFA, perfluoroethylene-propylene FEP, polytrifluorochloroethylene PCTFE, polyvinylidene fluoride PVDF start to answer With not only anticorrosive antioxidant effect is outstanding for these coatings, but also coefficient of friction is low, itself can be used as lubricant use, applies When being covered with buoy/floating ball of this type coating and moving in thick liquid, smaller with the frictional force of thick liquid, viscous force F is thus Become smaller.
Similarly, sensor measuring staff diameter is reduced, is coated with above-mentioned protective layer on the measuring rod, can also play anti-corrosion, lubrication, drop The effect of low viscous force F.
In conclusion in order to make buoy/floating ball, more smoothly with liquid fluctuating, reflect liquid level shape in real time in thick liquid State reduces viscous force F, prevents liquid that buoy/floating ball is sticked together with measuring staff, the present invention devises convex in hole inner edge It rises, reduces the area that buoy/floating ball central part hole is overlapped with measuring staff.The present invention has also inquired into protrusion in hole inner edge Arrangement rule, and the thus influence to hard magnetic material in protrusion, as far as possible by the arrangement of protrusion so that density of line of magnetic force reaches To maximum, obtain better inductive effects, induction range can be expanded in this way so that protrusion between measuring staff at a distance from increase feelings Under condition still can normal induction, that is, increase y, reduce viscous force F.Finally, the present invention starts with from coating, in metal or modeling It is coated with anticorrosion non-sticking lining on buoy/floating ball made of expecting, reduces frictional force of the buoy/floating ball by liquid.
By the above technological innovation, reduce the relative motion area A in viscous force formula, increase floating ball and measuring staff it Between gap, reduce the coefficient of friction on floating ball surface.Enable buoy/floating ball sensitive and accurately with liquid fluctuating, buoy/ Floating ball will not glue extremely on the measuring rod.
