The pump is characterized in that blind holes are arranged in the centers of curved surfaces of curved surface rotary tables; axial extension sections extending into the blind holes on the curved surface rotary tables are arranged in the middle of the two sides of a separation disc; the extension sections are provided with axial sliding chutes arranged in the same positions with sliding chutes on the separation disc; the upper and lower ends of slide dampers are widened; and the widened upper and lower ends are respectively inserted into through chutes on a pump shell and the axial sliding chutes on the extension sections on the separation disc. The pump has the beneficial effects that originally the single sides of the slide dampers, especially the extending end face of the separation disc, are locally stressed but at present the upper, middle and lower parts of the slide dampers, especially the extending end face of the separation disc, are simultaneously stressed, thus eliminating the defects that the original slide dampers are easy to jam and have high sliding frictional resistance as the single sides of the original slide dampers are locally stressed, so that the dampers move back and forth and slide flexibly, the frictional resistance is reduced, the dampers are not easy to damage and the useless power consumption of the pump is reduced; and the material selection range of the slide dampers is also widened, such materials with good wear resistance and low strength as modified plastics, ceramics and glass ceramics can be selected, the conveying pressure is also increased, the range of application of the rotary variable displacement pump is widened and the pump can be suitable for conveying various abrasive slurry.
Description
Technical field
The present invention is the improvement to axisymmetric curved surface rotary volume-variable pump, and it is wide to relate in particular to a kind of not only slide damper selection range, 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%, exceed about 30～40% than Ordinary Centrifugal Pumps efficient, especially use in small flow, high pressure operating mode, efficient can exceed about 40% than centrifugal pump, for example flow 20 ~ 30m
3/ h, the centrifugal pump of lift 0.8MPa, general efficient only has 35 ~ 40%, and carries the axisymmetric curved surface rotary volume-variable pump of same flow and lift, and its efficient is up to about 75%.In addition, also because being that volume gradual change compression realizes pumping, liquid linear velocity is lower in the pump, and is less to the wearing and tearing of pump erosion for this pump, thus at transfer of highly viscous liquid, contain the solid-phase material slurry and have original advantage.For example use at the various lots of petroleum crude oil of China and carry, existing Crude Oil Transportation multistage centrifugal pump power can be saved more than 35%, is a kind of comparatively ideal Crude Oil Transportation pump.And this pump can be just/counterrotating work.
Chinese patent 200620116360.9 discloses a kind of curved surface rotary volume-variable pump, basic structure such as Fig. 1,2, the assembling type pump cover 2.1 and 2.2 that comprises the cylindrical circular pump case 1 of inner chamber and two supports rotating shaft, two chambeies about the fixedly separator disc 5 at the axial middle part of pump chamber is divided into pump, the rotating shaft 7 of passing separator disc with the pump chamber dead in line, the opposed liquid entering hole 9 in pump case separator disc position and liquid outlet 8, separator disc both sides and pump chamber side face are rotatably assorted, relative and 180 degree that are staggered of curved surface, be fixed on the axisymmetric curved surface rotating disk 3.1 and 3.2 in the rotating shaft, axial slide is arranged in the middle of the separator disc liquid in-out mouth, but the interpolation axial reciprocating slides, be the telescopic baffle plate assembly 6 of elasticity, described baffle plate assembly 6 is by left baffle, middle guide pad and spring form, make left baffle be the elasticity Collapsible structure, the top pump case has baffle plate that groove and baffle plate cover plate 4 are installed.Working principle: separator disc two N-Side surfs in opposite directions, the axisymmetric curved surface rotating disk synchronous rotaries of curved surface dislocation 180 degree, produce respectively volume reducing (discharge) and volume in the slide damper both sides and increase (suction), about have 2 and discharge active chambers, 2 suck active chamber, discharge and suck fluid by drain groove on the separator disc is external, thereby realize row, the continuously conveying of suction of pump.Slide damper to-and-fro motion in the separator disc axial slide is by the curved surface rotating disk curved surface promotion of opposed 180 degree that are staggered of synchronous rotary.Yet this structure has just proposed a kind of imagination of axisymmetric curved surface rotary volume-variable pump, because lacking engineering operation considers, so that by this displacement pump that designs and produces, in engineering, lack actual application value, particularly working life is short, usually effectively work is no more than 20 days, thereby cause the actual invention of this displacement pump for many years, just rest on theory stage, so far do not have and reach the pump that satisfies Practical Project operation needs and put goods on the market, so market is this pump physical presence not, report is not arranged on the pump project handbook yet, the Crude Oil in China transfer pump still adopts the lower multistage centrifugal pump of efficient so far.
For example: the barrier width that endwisely slips of separating high and low pressure is identical with curved surface disk operation radius, and the slide damper that stretches out separator disc is supported by the monolateral line of separator disc chute fully.And slide damper both sides high-low pressure is poor larger; usually more than reaching up to 1MPa; the monolateral support of slide damper of stretching out separator disc is stressed; require very high to slide damper material bending strength; so can only adopt the metal of High anti bending strength; thereby it is good to have limited some rotproofness; the nonmetallic material that friction factor is low; such as modified ultra-high molecular weight polyethylene; modified Teflon; the plastics such as polyphenylene sulfide do slide damper (because of bending strength low; monolateral stressed flexible distortion; especially in conveying medium temperature (60 ℃ and more than) is arranged; 0.8MPa just deform; and then the normal slip of impact); also having limited simultaneously the rotary volume-variable pump can not be for delivery of Korrosionsmedium, and the metal slide damper also can only bear and is no more than the 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 local resistance increases when causing baffle plate to reciprocatingly slide, and causes easily the stuck or damage baffle plate of baffle plate, and can increase useless air horsepower consumption.Besides, the slide damper major function is to separate the height nip, and therefore under proof strength, Weir Plate Thickness is thinner, and the actual volume of pump is larger; But not crooked for the monolateral elevated pressures of bearing of opposing, must increase Weir Plate Thickness, thereby reduce the actual volume of pump.In addition, metal slide damper end raised line or roller continue and the friction of metal curved surface rotating disk curved surface, and both are all the hard material serious wear, cause slide damper and the shortening in working life of curved surface rotating disk.The separator disc function only be the tubular pump chamber is separated into about two chambeies, for reducing as far as possible pump volume and weight, separator disc only need reach the minimum thickness of intensity in theory, yet it is shorter to cause slide damper to move axial slide so again, 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, the thick 50 ~ 120mm that reaches of separator disc has increased so again pump volume and weight usually.
Above-mentioned deficiency still has is worth improved place.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of not only slide damper to move flexibly, and can bear higher fluid pressure, and can increase selection application, 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, the axial middle part of pump chamber is separated pump chamber and is fixed in the separator disc of the pump housing, the opposed liquid entering hole in pump case side face separator disc position and liquid outlet, the separator disc both sides are rotatably assorted with the pump chamber side face, curved surface is relative and 180 degree that are staggered, be fixed on the axisymmetric curved surface rotating disk in the rotating shaft, axial slide in the middle of the separator disc liquid in-out mouth, interpolation is the slide damper assembly in axial sliding.Described slide damper assembly is comprised of the baffle plate that horizontally slips, middle guide pad and spring, makes the baffle plate that horizontally slips be the elasticity Collapsible structure.Corresponding liquid entering hole one side of described slide damper is negative pressuren zone, and corresponding liquid outlet one side is the zone of high pressure.Slide damper top pump case has through slot, it is characterized in that there is blind hole in curved surface rotating disk center of surface section, separator disc two middle side parts have the section of extending axially that stretches into curved surface rotating disk blind hole, extend axially Duan Shangyu separator disc axial slide coordination and be provided with axial slide, slide damper is widened up and down, widens upper and lower end and inserts respectively in pump case through slot and the separator disc extension axial slide.
The object of the invention realizes, main improvement one is to be processed with blind hole in curved surface rotating disk center of surface section, the 2nd, be provided with the section of extending axially that stretches into curved surface runner blind hole at separator disc two middle side parts, and on the extension, have axial slide with separator disc axial slide coordination, the 3rd, slide damper is widened up and down, adding wide upper portion stretches in the pump case insertion through slot, widen the bottom and stretch into separator disc axially in the section of the prolonging axial slide, make slide damper upper, middle and lower three positions of widening in chute, greatly improved the anti-pressure ability of slide damper to high-pressure liquid, reduced the requirement of slide damper bending strength, simultaneously also improve slide damper and moved flexibility, overcome the deficiencies in the prior art, realized the object of the invention.
If the slide damper end arranges roller, a kind of better is that those widened sections length makes the slide damper end be " worker " font (upper and lower end stretches out) greater than the centre about making end face, and roller is positioned in the I-shaped indent.
Slide damper is widened rear top and the bottom and is inserted in pump case through slot and separator disc and the separator disc extension axial slide, end and detent ends may form partial closure's cavity volume when slide damper slided, when about slide damper, moving back and forth, because existing cavity volume, two ends can produce alternately malleation load and negative pressure load, thereby increased the slide damper running resistance, caused pump power consumption to increase.For avoiding this phenomenon, a kind of preferably pump case through slot is provided be used to the axial drain charge groove that is communicated with chute two ends pump chamber with the opposing side of separator disc and separator disc extension axial slide, and/or the slide damper bottom or the side opening that insert separator disc and separator disc extension axial slide are provided with for the axial drain charge groove (being end face groove and/or lateral groove) that is communicated with chute two ends pump chamber, make separator disc and axial slide two ends, separator disc extension liquid by the conducting of drain charge groove, move back and forth malleation and the negative pressure load that produces at two ends thereby eliminate baffle plate.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, the district's intercommunication of high and low pressure all can.
Move flexibility for improving slide damper, can also slide damper and separator disc and axial slide bottom surface, separator disc extension have vertical or be diagonal to some rollers of baffle plane or slide damper and separator disc and axial slide bottom surface, separator disc extension and/or end face between ball is arranged, make at the bottom of slide damper and the above-mentioned chute or end face by the large sliding friction of surface friction drag, become the little rolling friction of surface friction drag, it is more flexible that baffle plate is moved back and forth, with further reduction useless power consumption.Preferred vertical or be diagonal to the roller of baffle plane wherein, long-time running can not mark groove.In addition, ball is set between slide damper and above-mentioned chute bottom surface and/or end face or perpendicular to the roller on plane, also can plays conducting chute two ends, have equally the drain charge effect.
Cause slip not smooth for reducing slide damper stressed surface friction drag of single face in above-mentioned chute, can also offer axial notch at separator disc and separator disc extension axial slide and/or slide damper negative pressuren zone side (slip stress surface side), and/or between slide damper negative pressuren zone side and separator disc and the 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 negative pressuren zone side single face by liquid lubrication and low-friction material, it is more smooth and easy to guarantee that slide damper slides.
Because slide damper is in the change of chute stress performance, increase upper and lower end also stressed three positions are stressed by stressed the becoming of single face line, thereby the anti-folding of slide damper, bending resistance requirement have been reduced, thereby can adopt wear-resisting property good, but the modified plastics that intensity is low (for example modified ultra-high molecular weight polyethylene, modified Teflon, polyphenylene sulfide), and the rigidity such as pottery, sytull are large, poor toughness, wear resistance but well material make baffle plate.For further promoting temperature tolerance, deformation resistance and the wear resistance of slide damper, can in modified plastics, add the packings such as molybdenum disulfide, glass fibre, carbon fiber, silicon carbide, can also add again copper powder, further improve mechanical property.Can also bury metal body underground in the modified plastics slide damper gains in strength.So that slide damper had both enlarged application area, improved again 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, with respect to prior art, widen the slide damper structure owing to adopt, and make and widen upper and lower end and stretch in pump case and the separator disc both sides section of extending axially, so that slide damper especially stretches out the separator disc end face by former one-sided monolateral local pressure, and on becoming, in, lower three positions are stressed (slide damper three positions are all in chute) simultaneously, thereby it is easily stuck to have eliminated former slide damper single face local pressure, the shortcoming that sliding-frictional resistance is large, so that moving back and forth, baffle plate slides flexibly, the friction resistance reduces, and not fragile, the pump useless power consumption reduces.And because the slide damper upper and lower end is respectively in pump case chute and separator disc and the both sides section of extending axially chute thereof, so that slide damper anti-current body pressure capability significantly promotes, not only reduced the requirement to slide damper intensity, and the slide damper selection range is increased, such as the plastics that can select the poor rigidities such as modified Teflon, modified ultra-high molecular weight polyethylene, polyphenylene sulfide, and the rigidity such as pottery, sytull are large, and poor toughness, wear resistance be good material but.The same thickness slide damper has significantly improved discharge pressure, 60 ℃ of medium temperatures for example, and the plastic dam discharge pressure can be brought up to 0.8 ~ 1.2MPa, and the metal baffle discharge pressure can be brought up to 2.5MPa.The simultaneously application of nonmetal slide damper, not only so that the lifting of baffle plate wear-resisting property, improved the working life of slide damper and curved surface rotating disk, and provide precondition for research and development corrosion-proof type rotary volume-variable pump, and then enlarged the application area of rotary volume-variable pump, make the rotary volume-variable pump can be applicable to carry all kinds of abrasion slips.Widen the drain charge groove that is communicated with upper gliding groove two ends is set on the slide damper, and the upper and lower end face arranges roller and/or separator disc chute and/or slide damper negative pressuren zone side and offers axial notch, and/or the wear-resisting lining that greasy property is good, friction ractor is low is set between slide damper negative pressuren zone side and the chute, reduced especially useless power consumption.The slide damper developed width consists of this patent and prior art main distinction feature greater than curved surface runner face width.
