Description
Technical field
Model utility is the improvement to axisymmetric curved surface rotary volume-variable pump, relates in particular to the axisymmetric curved surface rotary volume-variable pump that smooth and easy, the invalid air horsepower of a kind of slide damper slip is little, baffle plate material range of choice is wide.
Background technique
Axisymmetric curved surface rotary volume-variable pump is a kind of newtype rotating displacement pump, its working efficiency is very high, and pumping efficiency exceeds 30～40% left and right up to 70 ~ 80% than Ordinary Centrifugal Pumps efficient, especially use in small flow, high pressure operating mode, efficient can exceed 40% left and right than centrifugal pump.Flow 20 ~ 30m for example
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 75% left and right.In addition, also because being that volume gradual change compression realizes pumping, in pump, liquid linear velocity is lower, 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 forward and reverse rotary 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, the pump chamber axially fixedly separator disc 5 at middle part is divided into two chambeies, left and right with pump, the rotating shaft 1 of passing separator disc with the pump chamber dead in line, the opposed liquid entering hole 3.1 in pump case separator disc position and liquid outlet 3.2, be communicated with the drain groove 5.1 and 5.2 of 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, curved surface relatively and 180 degree that are staggered, be fixed on the axisymmetric curved surface rotating disk 4 in rotating shaft, axial slide is arranged in the middle of separator disc liquid in-out mouth, but the baffle plate assembly 6 that the interpolation axial reciprocating slides.Wherein baffle plate assembly is comprised of left baffle 6.1 and 6.2, middle guide pad 6.3 and spring 6.4, 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 slide damper both sides and increase (suction), the left and right has 2 and discharges active chamber, 2 suck active chamber, externally discharge and suck fluid by drain groove on separator disc, thus realize pump row, inhale continuously and carry.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, consider owing to lacking engineering operation, make the displacement pump that designs and produces by this, lack actual application value in engineering, particularly working life is short, usually effectively work is no more than 20 days, thereby cause the actual model utility of this displacement pump for many years, just rest on theory stage, so far do not have to reach and satisfy the Practical Project process pump 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: separate the baffle plate that endwisely slips of the high and low nip of displacement pump, a side is the negative pressuren zone of imbibition, and opposite side is the zone of high pressure of output, and both sides pressure reduction is very large, generally all more than 1MPa.Slide damper is in the separator disc chute during axially reciprocating, objectively high-low pressure is poor to be affected owing to being subjected to, cause slide damper to be the suction side single face and be close to that wall friction reciprocatingly slides in chute, on the working surface of the nearly negative pressure of slide damper, every square centimeter of pressure that will bear 1～2MPa, under the effect of this pressure, between baffle plate and middle separate disk, surface friction drag significantly rises, make thus slide damper resistance to motion in chute increase, the power consumpiton of pump also significantly rises thereupon.Through test; fair at slide damper and chute surface of contact surface finishment; and in the situation of discharge pressure lower than 0.6MPa; power of motor consumption approximately increases by 15% left and right, if slide damper is surperficial, after carrying reasons such as containing solid particulate matter in liquid to cause the phenomenons such as wearing and tearing, plucking; or discharge pressure surpasses in the situation of 0.8MPa; air horsepower consumption can increase considerably, and general power of motor consumption can rise 30～50%, sometimes even can shut down because of stuck.
For solving above long-term scabrous problem, model utility people also adopts the material that changes slide damper, solves the surface friction drag problem of slide damper.Such as having adopted the materials such as ultra-high molecular weight polyethylene (UHMWPE), modified Teflon (PTFE) and polyphenylene sulfide (PPS), because the self-lubricating property of these materials is good, friction factor is low, test shows: the surface friction drag decrease of slide damper in the middle separate disk chute, the power consumpiton of pump is decrease thereupon also, compare with the slide damper of metal material, during pump operation, power of motor descends 15～20%.But because these materials are all the relatively low nonmetallic material of bad mechanical strength, serviceability temperature, the result of test show the pump discharge pressure lower than 0.6MPa, serviceability temperature lower than the operating mode of 60 ℃ in lower could normally the use, otherwise the slide damper of nonmetallic material will produce thermal distortion or pressure distortion damages, and has limited thus the application area of displacement pump.
Above-mentioned deficiency still has is worth improved place.
