Description
Technical field
The present invention is the improvement to axisymmetric curved surface rotary volume-variable pump, and not only slide damper selection range is wide to particularly relate to one, and using scope is wide, and can bear the axisymmetric curved surface rotary volume-variable pump of higher fluid pressure.
Background technique
Axisymmetric curved surface rotary volume-variable pump is a kind of newtype rotating displacement pump, its working efficiency is very high, pumping efficiency is up to 70 ~ 80%, about 30 ~ 40% are exceeded than Ordinary Centrifugal Pumps efficiency, especially use in small flow, high pressure operating mode, efficiency can exceed about 40% than centrifugal pump, such as flow 20 ~ 30m
3/ h, the centrifugal pump of lift 0.8MPa, general efficiency only has 35 ~ 40%, and carries the axisymmetric curved surface rotary volume-variable pump of same flow and lift, and its efficiency is up to about 75%.In addition, this pump is also because being that volume gradual change compression realizes pumping, and in pump, liquid linear velocity is lower, less to the wearing and tearing of pump erosion, thus at transfer of highly viscous liquid, have original advantage containing solid-phase material slurry.Such as be used in the various lots of petroleum crude oil conveying of China, more existing Crude Oil Transportation multistage centrifugal pump power can save more than 35%, is a kind of comparatively ideal Crude Oil Transportation pump.And this pump can be positive/negative to rotary work.
Chinese patent 200620116360.9 discloses a kind of curved surface rotary volume-variable pump, basic structure is as Fig. 1, 2, comprise the assembling type pump cover 2.1 and 2.2 of the cylindrical circular pump case 1 of inner chamber and two supports rotating shaft, pump is divided into two chambeies, left and right by the fixing separator disc 5 at the axial middle part of pump chamber, with the rotating shaft 7 of pump chamber dead in line through separator disc, the liquid entering hole 9 that pump case separator disc position is opposed and liquid outlet 8, separator disc both sides and pump chamber side face are rotatably assorted, curved surface relatively and be staggered 180 degree, be fixed on the axisymmetric curved surface rotating disk 3.1 and 3.2 in rotating shaft, axial slide is had in the middle of separator disc liquid in-out mouth, interpolation can be slided by axial reciprocating, baffle plate assembly 6 in resilientiy stretchable, described baffle plate assembly 6 is by left baffle, middle guide pad and spring composition, left baffle is made to be resilientiy stretchable structure, top pump case has baffle plate to install groove and baffle plate cover plate 4.Working principle: separator disc two N-Side surf in opposite directions, the curved surface dislocation axisymmetric curved surface rotating disk synchronous rotary of 180 degree, volume reducing (discharge) and volume increase (suction) is produced respectively in slide damper both sides, left and right has 2 and discharges active chamber, 2 suck active chamber, externally discharge by drain groove on separator disc and suck fluid, thus realizing row, the suction continus convergence of pump.Slide damper to-and-fro motion in separator disc axial slide, is promoted by the opposed curved surface rotating disk curved surface being staggered 180 degree of synchronous rotary.But this structure just proposes a kind of imagination of axisymmetric curved surface rotary volume-variable pump, consider owing to lacking engineering operation, make the displacement pump designed and produced by this, actual application value is lacked in engineering, particularly working life is short, usually effectively work is no more than 20 days, thus the actual invention of this displacement pump is caused for many years, just rest on theory stage, so far do not have to reach and meet Practical Project and run the pump of needs and put goods on the market, so market not this pump physical presence, pump project handbook there is not report yet, Crude Oil in China transfer pump still adopts the multistage centrifugal pump that efficiency is lower so far.
Such as: the barrier width that slides axially separating high and low pressure is identical with curved surface disk operation radius, the slide damper stretching out separator disc is supported by the monolateral line of separator disc chute completely.And slide damper both sides high-low pressure difference is larger, usually up to 1MPa and more than, the monolateral support of slide damper of stretching out separator disc is stressed, require very high to slide damper material bending strength, so the metal of High anti bending strength can only be adopted, thus some rotproofness are limited good, the nonmetallic material that friction factor is low, as modified ultra-high molecular weight polyethylene, modified Teflon, the plastics such as polyphenylene sulfide make slide damper (because bending strength is low, monolateral stressed flexible distortion, especially medium temperature (60 DEG C and more than) is had in conveying, 0.8MPa just deforms, and then the normal slip of impact), also limit rotary volume-variable pump can not be used for carrying Korrosionsmedium simultaneously, and metal slide baffle plate also can only bear and be no more than 1.2MPa working pressure.Secondly, slide damper is monolateral stressed, and baffle plate and separator disc chute end face force bearing point concentrate on an ordinate, and when causing baffle plate to reciprocatingly slide, local resistance increases, and easily causes the stuck or damage baffle plate of baffle plate, and can increase useless air horsepower consumption.Besides, slide damper major function separates height nip, and therefore under proof strength, Weir Plate Thickness is thinner, and the actual volume of pump is larger; But bear elevated pressures for opposing is monolateral not bend, Weir Plate Thickness must be increased, thus reduce the actual volume of pump.In addition, metal slide baffle plate end raised line or roller continue to rub with metal curved surface rotating disk curved surface, and both are all hard material serious wear, cause slide damper and the shortening in working life of curved surface rotating disk.Separator disc function is only tubular pump chamber is separated into two chambeies, left and right, for reducing pump volume and weight as far as possible, separator disc only need reach the minimum thickness of intensity in theory, but it is shorter to cause slide damper to move axial slide again like this, and too short axial slide can affect the reliable slippage of baffle plate; For guaranteeing that slide damper reliably moves back and forth, must thicken separator disc thickness, usual separator disc is thick reaches 50 ~ 120mm, turn increases pump volume and weight like this.
Above-mentioned deficiency still has the place being worth improving.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide one not only slide damper move flexibly, and can higher fluid pressure be born, and selection application can be increased, the axisymmetric curved surface rotary volume-variable pump that using scope is wide.
The present invention is in order to solve the problems of the technologies described above, provide following technological scheme: axisymmetric curved surface rotary volume-variable pump, comprise the cylindrical circular pump case of inner chamber, pump chamber axially middle part is separated pump chamber and is fixed on the separator disc of the pump housing, the liquid entering hole that pump case side face separator disc position is opposed and liquid outlet, separator disc both sides are provided with and are rotatably assorted with pump chamber side face, curved surface relatively and be staggered 180 degree, be fixed on the axisymmetric curved surface rotating disk in rotating shaft, axial slide in the middle of separator disc liquid in-out mouth, axial slide interpolation can slide damper assembly in axial sliding, described slide damper assembly is by the baffle plate that horizontally slips of axis, middle guide pad and spring composition, slide damper assembly is made to be resilientiy stretchable structure, the corresponding liquid entering hole side of described slide damper is negative pressuren zone, corresponding liquid outlet side is zone of high pressure, above slide damper, pump case has through slot, it is characterized in that there is blind hole in curved surface rotating disk center of surface portion, separator disc two middle side part has the axial extension stretching into curved surface rotating disk blind hole, axial extension is provided with axial slide with separator disc axial slide coordination, slide damper is widened up and down, widen upper and lower end to insert respectively in pump case through slot and separator disc extension axial slide.
The object of the invention realizes, main improvement one is processed with blind hole in curved surface rotating disk center of surface portion, two is that separator disc two middle side part is provided with the axial extension stretching into curved surface runner blind hole, and axial slide is had with separator disc axial slide coordination on extension, three is widened up and down by slide damper, adding wide upper portion stretches in pump case insertion through slot, widening bottom stretches in the axial section of the prolonging axial slide of separator disc, make slide damper upper, middle and lower three position widened in chute, substantially increase the anti-pressure ability of slide damper to high-pressure liquid, reduce the requirement of slide damper bending strength, also improve slide damper simultaneously and move flexibility, overcome the deficiencies in the prior art, realize the object of the invention.
If slide damper end arranges roller, one is better make the upper and lower those widened sections length of end face be greater than centre, and make slide damper assembly end in " work " font (upper and lower end stretches out), roller is positioned in I-shaped indent.
Slide damper is widened rear top and the bottom and is inserted in pump case through slot and separator disc and separator disc extension axial slide, when slide damper slides, end and detent ends may form partial closure's cavity volume, when moving back and forth about slide damper, alternating positive load and negative pressure load can be produced because two ends exist cavity volume, thus add slide damper running resistance, cause pump power consumption to increase.For avoiding this phenomenon, a kind of preferably pump case through slot is provided with for being communicated with pump case through slot with the opposed slot bottom surface of separator disc and separator disc extension axial slide, the axial drain charge groove of pump chamber two ends, axial slide two ends pump chamber, and/or insert the slide damper bottom of separator disc and separator disc extension axial slide or side opening is provided with for being communicated with pump case through slot, the axial drain charge groove (i.e. end face groove and/or lateral groove) of pump chamber two ends, axial slide two ends pump chamber, make separator disc and axial slide two ends, separator disc extension liquid by the conducting of drain charge groove, thus elimination baffle plate moves back and forth the malleation and negative pressure load that produce at two ends.Drain charge slot cross-section shape is not limit, and can be triangle, square, spill or circular hole etc., as long as can be communicated with separator disc and axial slide two ends, separator disc extension drain, make the intercommunication of high and low pressure area.
Flexibility is moved for improving slide damper, can also have in slide damper and separator disc and axial slide bottom surface, separator disc extension vertical or be diagonal between some rollers of baffle plate bottom end or slide damper and separator disc and axial slide bottom surface, separator disc extension and/or end face and have ball, make at the bottom of slide damper and above-mentioned chute or end face by the large sliding friction of surface friction drag, become the rolling friction that surface friction drag is little, baffle plate is moved back and forth more flexible, to reduce useless power consumption further.Wherein preferred vertical or be diagonal to the roller of baffle plane, long-time running can not mark groove.In addition, between slide damper and above-mentioned chute bottom surface and/or end face, ball or the roller perpendicular to plane are set, also can play conducting chute two ends, there is drain charge effect equally.
Cause slip not smooth for reducing slide damper stressed surface friction drag of one side in above-mentioned chute, axial notch can also be offered at separator disc and separator disc extension axial slide and/or side, slide damper negative pressuren zone (slip stress surface side), and/or between side, slide damper negative pressuren zone and separator disc and separator disc extension axial slide, the wear-resisting lining that greasy property is good, friction ractor is low is set.Reduce the stressed surface friction drag of side, negative pressuren zone one side by liquid lubrication and low-friction material, guarantee that slide damper slides more smooth and easy.
Because slide damper is in the change of chute stress performance, stressed from stressed three positions becoming increase upper and lower end also stressed of one side line, thus the anti-folding of slide damper, bending resistance requirement is reduced, thus wear-resisting property can be adopted good, but the modified plastics that intensity is low (such as modified ultra-high molecular weight polyethylene, modified Teflon, polyphenylene sulfide), and the rigidity such as pottery, sytull is large, poor toughness, wear resistance but well material make baffle plate.For promoting the temperature tolerance of slide damper, deformation resistance and wear resistance further, the packings such as molybdenum disulfide, glass fibre, carbon fiber, silicon carbide can be added in modified plastics, copper powder can also be added again, improve mechanical property further.Metal body can also be buried underground in modified plastics slide damper to gain in strength.Make slide damper both expand application area, turn improve wear-resisting property, increase slide damper working life.
Beneficial effect of the present invention: axisymmetric curved surface rotary volume-variable pump of the present invention, relative to prior art, slide damper structure is widened owing to adopting, and make to widen upper and lower end and stretch in the axial extension of pump case and separator disc both sides, slide damper is made especially to stretch out separator disc end face by former one-sided monolateral local pressure, and on becoming, in, lower three positions simultaneously stressed (slide damper three position is all in chute), thus it is easily stuck to eliminate former slide damper one side local pressure, the shortcoming that sliding-frictional resistance is large, baffle plate is moved back and forth and slides flexibly, friction resistance reduces, and it is not fragile, pump useless power consumption reduces.And because slide damper upper and lower end is respectively in pump case chute and separator disc and both sides thereof axial extension chute, slide damper resist fluids pressure capability is significantly promoted, not only reduce the requirement to slide damper intensity, and slide damper selection range is increased, such as can select the plastics of the poor rigidities such as modified Teflon, modified ultra-high molecular weight polyethylene, polyphenylene sulfide, and the rigidity such as pottery, sytull is large, poor toughness, wear resistance but good material.Same thickness slide damper, significantly improves discharge pressure, such as 60 DEG C of medium temperatures, and plastic dam discharge pressure can bring up to 0.8 ~ 1.2MPa, and metal baffle discharge pressure can bring up to 2.5MPa.The application of nonmetal slide damper simultaneously, baffle plate wear-resisting property is not only made to promote, improve the working life of slide damper and curved surface rotating disk, and provide precondition for researching and developing corrosion-proof type rotary volume-variable pump, and then expand the application area of rotary volume-variable pump, make rotary volume-variable pump can be applicable to carry all kinds of abrasion slip.Widen drain charge groove slide damper being arranged and is communicated with upper gliding groove two ends, and upper and lower end face arranges roller and/or separator disc chute and/or side, slide damper negative pressuren zone and offers axial notch, and/or the wear-resisting lining that greasy property is good, friction ractor is low is set between side, slide damper negative pressuren zone and chute, be more reduction of useless power consumption.Slide damper developed width is greater than curved surface runner face width, forms this patent and prior art main distinguishing feature.
