Abstract
The invention provides an axisymmetric curved surface rotary variable displacement pump. Compared with the prior art, the pump has the beneficial effects that stressed planes of ends of slide dampers are greatly reduced or eliminated by increasing diameters of idler wheels at the ends of the slide dampers or enabling chamfers of the stressed planes of the ends of dampers to be inclined planes or arc planes, meanwhile, when the slide dampers move to low point-high point transition inclined planes of curved surface rotary tables, the width sides of the damper ends can not be contacted with curved surfaces of the rotary tables and are stressed, thus furthest reducing or eliminating counter pressure of high pressure fluid in the pump on the end faces of the slide dampers, ensuring that the slide dampers can not be compressed by the high pressure fluid and undergo interstitial separation and overcoming the defects caused by momentary separation of the dampers and the curved surfaces of the rotary tables because the ends of the slide dampers in the prior art have stressed planes, especially the critical defect of short actual service lives; and no reduction of the efficiency of the rotary variable displacement pump running a long term can be ensured.
Description
Technical field
The present invention is the improvement to axisymmetric curved surface rotary volume-variable pump, relates in particular to a kind ofly can guarantee that the rotary volume-variable pump efficiency is high, noise is low, vibrations are little, the axisymmetric curved surface rotary volume-variable pump of slide damper and curved surface rotating disk long service life.
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 3 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 1 of passing separator disc with the pump chamber dead in line, the opposed liquid entering hole 7 in pump case separator disc position and liquid outlet 6, the drain groove 5.1 and 5.2 that is communicated with both sides on the thickness face of separator disc liquid in-out mouth position, 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 4.1 and 4.2 in the rotating shaft, in the middle of the separator disc liquid in-out mouth axial slide is arranged, but the baffle plate assembly 8 that the interpolation axial reciprocating slides.Wherein baffle plate assembly is comprised of left baffle 8.1 and 8.2, middle guide pad 8.3 and spring 8.4, makes left baffle be the elasticity Collapsible structure.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: it is high to separate displacement pump, the baffle plate that endwisely slips of low pressure area, one side is the low pressure area of imbibition, opposite side is the zone of high pressure of output, contact the slide damper end of separating the height nip with the axisymmetric curved surface rotating disk, long-time and curved surface rotating disk curved surface sliding friction, for alleviating and the contact wear of curved surface rotating disk, employing is offered circular hole in the end, place circular roller or roller (following general designation roller), slide damper end face middle part roller cylindrical is contacted with the line that the curved surface rotating disk is the surface of contact minimum, reduce slide damper end face and curved surface rotating disk surface friction drag and reduce wearing and tearing with this, prolong slide damper and/or curved surface rotating disk working life.Yet owing to only be to consider from alleviating sliding friction, be arranged on roller 10 diameters of slide damper end face much smaller than Weir Plate Thickness (end face exposes seldom circular arc), make slide damper end rollers both sides have larger plane of constraint 11 (Fig. 3).And this pump slide damper both sides high-low pressure is poor larger, usually up to more than the 1MPa, the high-pressure liquid that compression forms can produce axial pushing tow compression to this plane, especially when moving to the high point of curved surface section A (Fig. 4), the plane that the end rollers both sides are larger, also can cause baffle plate end wide roller low pressure area side and curved surface contact (Fig. 3), cause the baffle plate end rollers to separate with curved surface rotating disk moment, slide damper end face and curved surface turntable clearance are increased, end face and highly pressurised liquid area of contact have been strengthened, and then increased the back-pressure thrust of pressure fluid to slide damper, cause slide damper end and curved surface rotating disk to produce intermittence and separate.Separate with the curved surface turntable intermittent slide damper end: the one, and cause high-pressure liquid to leak to the channelling of baffle plate opposite side low pressure suction area, reduce the actual output quantity of pump (reducing pump work efficient), and efficient increases with outlet pressure and reduces, the theoretical efficiency value significantly descends, and the highlyest lowers efficiency 15～20%; And along with prolong working time, slide damper medi-spring 8.4 is because repeatedly significantly being compressed, produce the fatigability flexibility decrease, baffle plate end face and curved surface rotating disk interface pressure are reduced, and then further channelling is leaked in increase, cause at actual motion after 10～20 days, pump duty and outlet pressure significantly descend, two indexs generally will descend 15～20% simultaneously, carry in the above high pressure of 1Mpa, efficient only has 65～70%, especially when conveying contains solid-phase material crude oil, generally is difficult to working life above 10 days.The 2nd, intermittent separate (about 800 rev/mins of the rotating speeds) of slide damper high frequency, so that slide damper and curved surface turntable surface produce the high frequency bump, not only very easily cause the wearing and tearing of baffle plate end face roller impact, shortened baffle plate working life, the engineering operation baffle plate only has 10～15 days actual life, also can cause simultaneously the curved surface disc surfaces to produce local damage, surperficial crudeization because impacting, slide damper and curved surface surface friction drag increase, and cause the pump power consumption to increase; And high-frequency pulse formula bump, (outlet does not have noise, vibration without pressure during operation for noise when also having increased pump operation and vibrations, as long as pump discharge one has pressure, noise, vibration are just amplified, and pressure is higher, noise, vibrations are larger), vibrations produce bearing and shaft sealing is obviously shortened working life.Although can deal with the high-pressure liquid back pressure by increasing the slide damper inner spring intensity of pressure in theory, but causing having increased between baffle plate and curved surface rotating disk, increase spring pressure intensity results weares and teares, cause equally baffle plate and the shortening in working life of curved surface rotating disk, the spring pressure strength increase also causes the pump power consumption to increase simultaneously, increases operation energy consumption.In addition, slide damper high-frequency pulse formula bump like this, also limited the selection of roller material, usually can only adopt metal to make roller, and the common metal roller, its wear resistance is relatively poor, and this also is to cause a short major reason of actual life, and Metal Contact Rollers has also limited it and can not be used for using with granule medium.Although all good nonmetallic material of some Economy, wear resistance and processability are arranged in the engineering, such as silicon carbide, aluminium oxide ceramics, zirconium oxide, sytull etc., because the large weakness of himself intrinsic fragility, high-frequency pulse formula bump is easy to cause cracked, thereby can't be used for the baffle plate end rollers.Use short-term (10～15 days) internal leakage serious, rated flow reduces, decrease in efficiency, and pump power increases, noise, vibrations are large, and baffle plate and curved surface rotating disk short five large shortcomings in working life are difficult to overcome, become for this reason impassable obstacle of pump input engineering operation, fail for a long time to solve.
In addition, existing axisymmetric curved surface rotary volume-variable pump, the pump liquid entering hole is identical with the design of fluid oral pore sectional area, because the liquid outlet hydrodynamic pressure is high, flow velocity is fast, for example when discharge pressure is 0.8MPa, flows 10～15 meters of scooter per seconds; And the liquid sucting port negative suction is lower, and under aforementioned delivery pressure, negative suction only is-0.02MPa that flow velocity can only reach 4～6 meters.So at one time, flow by the liquid in-out mouth produces very large difference, cause suction port feed liquor flow to be significantly less than the liquid outlet output flow, the consequence of generation will reduce pump real work efficient equally, and can produce cavitation erosion property noise because of the low flow velocity of liquid sucting port.
Above-mentioned deficiency still has is worth improved place.
