Description
Technical field
The present invention is subordinate to mechanical manufacturing field, relate to the multiple mechanical device that comprises a same configuration, more specifically be that a kind of can realization manufactured simple economy, accurate, low wearing and tearing long lifetime of flow linearity, the high requirement of the little efficiency of volume, be applied to a kind of mechanical structure of the product manufactures such as positive displacement pump and all Related products that derive, with realize various gas, liquid, etc. carry transfer, metering and mechanical transmission.Mainly comprise oil hydraulic pump, oil hydraulic motor, metering pump, flowmeter, oil pump, water pump (especially pressure requires high fire water pump and building raw water service pump), chemical pump, food pump, air pump, vacuum pump, deduster negative-pressure air fan, even power device for generating hydroelectricity etc.
Background technique
Owing to the invention relates to the invention of a kind of mechanical structures of product such as pump, relate to product category more, because main structure is identical with working mechanism, pardon and describe in detail one by one, now take oil hydraulic pump as main, and be illustrated other Related product is subsidiary.
Its flow of oil hydraulic pump in ideal should with the linear direct ratio of drive shaft speed, when driving invariablenes turning speed, can realize the output of flow steady, and without entrap phenomenon, can realize stable working noise free, to improve working environment.In measuring apparatus, can realize pump and flowmeter unites two into one (metering pump), thereby reduce equipment manufacture cost, weight reduction, or improve flowmeter measuring accuracy.Pump in ideal also should be simple in structure, and easy to manufacture, volume is little, to realize low cost.Pump in ideal also should rub little, to reduce wearing and tearing, increases the service life.Pump in ideal also should have good suction capacity, can realize auto-pumping, also can improve worry dirt device air mass flow in order to form high vacuum pressure reduction.Pump in ideal also should have higher working efficiency, to save the energy.Its rotatable parts of pump in ideal are answered symmetrical configuration balance, can run up and shockproof and noise, to reduce the volume and weight of pump and power plant.Pump in actual use, all can not have These characteristics completely at present, due to various in style, is not illustrated one by one.Now only from the most economical at present, application surface the most widely gear pump and blade type centrifugal (eddy current) pump is that example is explained.Though gear pump is simple in structure, compare other positive displacement pump cost relatively low, Gear Processing needs special device and technology, and machining accuracy is high, so technical threshold is high; And rely on flank engagement sealing, engagement place exists rolls and sliding friction, because therefore flank of tooth carrying working load causes tooth surface abrasion, must bestow lubricated, can not be for the conveying of the fluids such as water, food; Flow pulsation large and have entrap phenomenon so operating noise large, maximum speed is limited by Gear shape process precision; Be subject to the restriction of cog machining, be difficult to realize super-flow.Blade type centrifugal (eddy current) is though pump is simple in structure, also easy to manufacture, the low wearing and tearing of cost are little, but suction capacity is poor, and working pressure is low (can only improve pressure by the mode of plural serial stage while applying to fire water pump, cost and volume, weight have been increased), can only rely on high working speed and be achieved, not only improve the requirement to power plant, also bring extra energy consumption (power consumption is directly proportional to the cube of rotating speed), efficiency is low, wastes energy; And can only one-way only operation, controlling direction of flow must be by multiple-way duct and at least 4 valve, and size that can not coutroi velocity with dam; Although blade type centrifugal (eddy current) pump can be by taking the modes such as immersion to overcome suction capacity deficiency (as submersible pump, high to the seal request of power plant motor, easy making moist damaged and electric leakage accident).Flow is subject to the impact of working pressure large, is inverse relation.Low vacuum while applying to deduster, energy consumption is large.Compare blade type centrifugal (eddy current) pump, it is high that positive displacement pump has working pressure, stability of flow is controlled, suction capacity is strong, can two-way working, and efficiency is high, the advantage of energy-conservation (the linear direct ratio of power consumption and rotating speed), but existing positive displacement pump ubiquity complex structure, manufacture difficult, cost is high, wearing and tearing are large, easy clamping stagnation, very difficult replacement blade type centrifugal (eddy current) pump, application area is subject to great restriction.As everyone knows, straight-line reciprocating pump is the simplest, most effective, wear and tear minimum, the positive displacement pump that degree of vacuum is the highest, has the good characteristic that flow and piston movement speed are linear proportional relation, when keeping piston traveling speed invariable, can realize the constant flow pulsating movement free of pump, be Utopian pump.Regrettably be subject to the restriction of piston stroke, cannot continuous firing.Because power plant are realized lasting outputting power in the mode of rotating conventionally, the coupling that can only carry out linear reciprocation and circular-rotation by crank block and cam mechanism is at present changed.Mainly contain radial and axial plunger pump etc.Have flow pulsation, easy to wear, complex structure cost is high, and volume is large, the vibration problem such as can not run up greatly.As the axis of straight-line reciprocating pump (cylinder body) is transformed into the circle that the whole story, end overlapped by straight line, now cylinder body is with " C " font annulus that the whole story, end cut off, piston is driven along circular cylinder and is constantly passed through and hold the whole story partition continuous circulation to rotate by round rotor shape piston rod, likely realizes all good characteristics of straight line motion reciprocating pump.The pump with annular cylinder, piston, rotor structure, according to piston, cross the pattern that the whole story, end cut off, mainly contain at present flexible avoiding type: as vane pump (forming end partition at the whole story by bias) and patent CN90101741 gate type hydraulic pump (motor) etc., by piston radial, stretch to realize dodging to hold the whole story to cut off to realize and pass through.Its deficiency is that piston wear is large, complex structure etc.Double pump leap type in parallel complementary staggered: as inside and outside gear pump etc., adopt many pistons cascaded structure, the intermeshing sealing of two pump pistons, double-pump complementation, the piston of a pump is also that the end at the whole story of another pump cuts off, the interlaced leap that continues, and its deficiency is that flow pulsation is large, have entrap phenomenon, operating noise is large etc.Piston is from turning around more type: as patent CN201010601531 rotary piston pump, take a plurality of fan-shaped pistons not only with rotor, to be revolved round the sun together by gear transmission, also simultaneously along the synchronized rotation of rotor sense of rotation, thereby walk around end partition at the whole story, although it can realize linear flow, but must at least 6 pistons, 7 gears, therefore cost is high, and under self-priming working state, piston proceeds to effective swept volume larger of volume of air that low-pressure cavity carries and pump from hyperbaric chamber, so low vacuum, and self-priming performance is poor.As can be seen here, the pump of prior art structure is difficult to reach or approach the perfect condition of straight line motion reciprocating pump.Gear pump and blade type centrifugal (eddy current) pump is low and most widely used in volume and on-positive displacement pump product respectively with its cost easy to manufacture.If find a kind of structure, more simply manufacture the mode of passing through end partition at the whole story that easier cost is lower, create a kind of perfect new pump kind that embodies all good characteristics of straight line motion reciprocating pump, will replace gear pump and most of blade type centrifugal (eddy current) pump, the main flow that becomes the products such as pump class, market prospects are extremely wide.And can cause the change of a series of Related product costs, performance.As: its high efficiency can make to adopt the dedusting negative-pressure air fan of blade type centrifugal (eddy current) pump structure, and the energy consumptions such as water conservancy lift pump reduce greatly; Hydraulic generating equipment, energy utilization rate is more high.There are great economic implications and far-reaching social effect.
Summary of the invention
As mentioned above, prior art is dodged by flexible, and double-pump complementation is staggered to be crossed over, and piston is from the structure such as turning around more, makes piston cross whole story end and cuts off, and has realized circular cylinder piston cycle running continuous operation.Obviously, combination property is all undesirable.And piston does not have at present around circle translation crossing structure and sets foot in, and to realize, must solve piston around circle translation problem.The present invention, according to the movement characteristic of connecting rod in constant speed cross crank gear, has successfully solved this problem, creates the product structures such as a kind of Utopian pump (motor).The oil hydraulic pump of now take is illustrated its structural feature and beneficial effect as example.Be achieved by the following technical solutions.
The present invention moves in all pump classes of piston structure and its class Related product oil hydraulic pump etc. and mainly comprises the circle jointly consisting of a plurality of parts " C " shape circular cylinder with revolving, at least two pistons, a rotor, at least with many groups cross crank gear of number of pistons correspondent equal; In described piston and cross crank gear, connecting rod is fixedly connected.Concrete structure feature and corresponding function beneficial effect are:
Described circle " C " shape circular cylinder consists of jointly housing, rotor.Described housing has a cylindrical form interior surface, and described rotor comprises the side cover part at pellet and its two ends.Described rotor pellet is partly a cylindrical body, and in axis and housing, barrel surface axis coincides.Described rotor-side cap is divided into pie cylindrical body, is positioned at rotor pellet part both side ends, and airtight the touching of external cylindrical surface and housing inner cylindrical surface closed.Therefore housing and rotor form an airtight round "O" ring shape cylinder body.On its cylindrical form interior surface of described housing, also comprise and hold the whole story to axle center projection partition body to divide.Described housing end at the whole story cuts off body and is divided into the projection that a cross section is one section of " C " shape ring-type, airtight the touching of end and rotor-side cover interior edge face closed, airtight the touching of inner cylindrical surface and rotor pellet part external cylindrical surface closed, and therefore will justify the airtight partition of "O" ring shape cylinder and form circle " C " shape circular cylinder.Described rotor pellet part is along being circumferentially also evenly equipped with the circular cross-section groove that quantity equates with number of pistons.Described piston is that a cross section is the fan-shaped column-shape showering structure of approximate circle, place, axle center comprises a transmission shaft structure, by axle center, locate to be installed in the circular cross-section groove of rotor pellet part with the circular hole of transmission shaft with footpath on transmission shaft and rotor-side cover, and can rotate along circular cross-section recess axis, airtight the touching of external cylindrical surface and circular cross-section groove inner cylindrical surface closed, airtight the touching of end face and rotor-side cover interior edge face closed, and while being positioned at working position, tangent and airtight the touching of the external cylindrical surface of piston and housing cylindrical form interior surface closed.Thereby circular cylinder is divided into two mutual airtight high low pressure active chambers.Described housing end at the whole story cuts off body and divides the arc length of inner cylindrical surface cross section circular arc to be not less than the arc length that rotor pellet part external cylindrical surface cross section circular arc is positioned at circular cross-section groove slot-open-section.Guaranteed that end cut off body and divided on rotor pellet circular cross-section groove and piston to remain airtight partition state through out-of-date housing whole story, cut off reliable.Described piston sector crosssection external arc arc length is not less than N/mono-(N is the number of fan-shaped column-shape showering piston) of same radius circumference.Guaranteed energy seamless connection between each piston, alternation.Described housing is positioned to hold on the cylindrical form interior surface that cuts off body both sides and has fluid inlet and outlet the whole story.Described rotor is also provided with a driving (output) axle in one place, side cover end face axle center.The basic structure and the element of work that have possessed the devices such as pump.Described cross crank gear comprises rotor-side cover, connecting rod and multi-joint crank; Described connecting rod is positioned at the outside of rotor-side cover, and one end is fixedly connected with piston by the overhanging end of transmission shaft part, piston axes place, and the other end and multi-joint crank are hinged.Therefore, piston autorotation is pind down by the connecting rod in cross crank gear.Described multi-joint crank comprises a plurality of crank sections, is the cointegrate of a plurality of cranks.Described rotor-side cover also comprises a plurality of crank sections, for another organizes the cointegrate of a plurality of cranks.Therefore number of spare parts is few, and cost simple and compact for structure is low.Described multi-joint crank, be arranged in the end cap part of housing, can be along housing end plug Plane Rotation, its center of rotation and axis of rotor rotation are in the heart apart from the effective active length that equals each connecting rod, and the effective active length of each crank equals the distance at fan-shaped column-shape showering piston rotation center and rotor center.Therefore be constant speed cross crank gear, the speed of autorotation of connecting rod and piston is zero.Therefore piston can be driven and be done circulation parallel along circular cylinder circular axis by rotor, and that realizes continous-stable rotates translation around circle.When taking suitable piston cross-section shape, can realize the accessible end partition body at the whole story that passes through of piston, from the end of circle " C " shape circular cylinder, return to the work of starting point repetitive cycling.When adopting the simple structure that number of pistons is 2, also at least comprise an auxiliary cross crank gear, the effective active length of its auxiliary connecting rod is identical with other connecting rods, hinged with rotor-side cover and two crank cointegrates of multi-joint crank respectively, and keep an appropriate phase angle with other cross crank gears.Solved transmission dead unit problem, guaranteed also can rotate when only having 2 pistons smooth and easy.Can simplify by implementation structure number of spare parts, overall volume, minimize weight, minimumization of manufacture cost most.
From its work and structural feature, piston when passing through whole story end and cut off body other outer surface except work cylndrical surface and two end faces with the whole story end cut off body and can be contactless state, so to its shape without specific (special) requirements, requirement on machining accuracy is low.While being generally minimizing vacuum draw, piston proceeds to low-pressure cavity from hyperbaric chamber and carries the portion gas backflow that air causes, gas clean-up, should keep as far as possible holding at itself and the whole story the less dynamic slit of cutting off between body, to reduce to greatest extent without the return volume of work efficiency, under the perfect condition without dynamic slit, its shape is only the inner cylindrical surface being equated around rotor axis turning radius with piston by two radiuses, an external cylindrical surface tangent with holding partition body inner cylindrical surface the whole story forms, therefore without complicated processing face, manufacture simple.The oil-free vacuum pump that is particularly suitable for working under dust atmosphere.Smooth and easy for keeping keeping again liquid to flow compared with small gap, on the cylinder that can not contact with housing at piston, have logical oil groove or end face chamfering or oil groove, not only avoided such as the entrap phenomenon in oil pump, simultaneously also avoided piston fluctuation of flow during to another active chamber transition by an active chamber, guaranteed any time flow and drive shaft speed all remain desirable linear proportional relation.Also can take to hold the whole story partition body to be placed in lowest part, the position of fluid inlet and outlet is higher than end partition body at the whole story, make to retain all the time in pump a certain amount of liquid, to guarantee at any time, hold the whole story partition body and piston etc. to be immersed in completely in liquid, piston passes through the whole story can only bring liquid into low-pressure cavity when end cuts off body, and gas can not be refluxed, and can realize limiting vacuum suction.
Above-mentioned technical characteristics, be applied in different products, existing common simple in structure, cost easy to manufacture is low, the low feature of wearing and tearing, also there is its distinctive beneficial effect: while being applied to oil hydraulic pump (motor), also there is stable working noise free, the feature that the high volume of symmetrical configuration balancing speed is little, also has the high feature of the strict linear direct ratio measuring accuracy of flow corner while being applied to flowmeter (metering pump).Being applied to transfer pump, also to have suction capacity good, stability of flow, and pressure is high, energy-efficient feature (fire water pump and building tap water transfer pump etc.).Be applied to vacuum pump and also have that degree of vacuum is high (can replace centrifugal dedusting negative-pressure air fan during large flow, can improve deduster filtration pressure difference, improve filter dirt effect, energy-efficient) feature, be applied to water conservancy lift pump energy-saving significance great, be used for replacing water turbine and carry out hydroelectric power, can further improve energy utilization rate.Therefore application surface is extremely extensive, effect and ideal thereof.
Owing to taking the transmission of constant speed double crank mechanism, so working speed is no longer subject to the restrictions such as accuracy of manufacturing, and rotating speed is limitless in theory, can realize the volume and weight that reduce self and drive unit by high design speed.The impact that the contact of the sealing surface of each phase mutual friction is little and stable, be not subject to work loads, double crank mechanism is only born the effect that maintains piston parallel attitude, stressed relevant with piston movement surface friction drag, load is low, thus structural strength require low, take volume little, wear and tear little, loss is low.
The present invention with revolve move all pump classes of piston structure and its class Related product also by its piston, the whole story end cut off the coated one deck sealing material of external surface, thereby not only promoted and have held the sealability of cutting off body at piston and the whole story, also can be by selecting suitable sealing material and suitable sealing material thickness and structure, make between the sealing surface of relative sliding is non-rigid contact, there is certain anti-sticking stickiness energy, reduce the requirement to working medium and filtrating equipment, expanded the application area (as water conservancy lift pump and water power plant hydrodynamic apparatus etc.) of positive displacement pump.Also by setting up the seal ring of an odd-shaped cross section between the external cylindrical surface at rotor tip side cover and housing inner cylindrical surface, sectional shape be by 3/4ths circle and two tangent with it, mutually vertical, the straightway that length equates with radius of a circle forms, straightway is positioned at housing end face and rotor side cover external cylindrical surface place, solved the sealing problem along the circumferential direction that the indeterminable annular working cylinder of conventional seals circle is special procured, thereby realize gap-free sealed between all associated components, also possessed the good performance of damming.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further with revolving working principle and the embodiment of moving all pump classes of piston structure and its class Related product oil hydraulic pump etc.:
Embodiment of the present invention oil hydraulic pump as visible in Fig. 1 a, Fig. 2 is mainly by housing (1), and housing end plug (3), holds and cut off body (4) whole story, rotor pellet (5), rotor side cover (6), (7), piston (8), (9), the compositions such as connecting rod (10), (11) and multi-joint crank ring (12).Rotor pellet (5) is positioned at housing (1), and rotor side cover (6), (7) are positioned at rotor pellet (5) two ends, and housing (1) forms an airtight circular cylinder with rotor.It is upper that end partition body at the whole story (4) is positioned at housing (1), forms circle " C " shape annular cylinder.Piston (8), (9) are arranged in two symmetrical circular grooves of rotor pellet (5), rotor side cover (6), (7) by rotor pellet (5) two ends are fixing, and can rotate along circular cross-section recess axis, sector crosssection outer arc radius equates with the radius of rotor pellet (5) circular cross-section groove, the inner cylindrical surface of the external cylindrical surface of piston (8), (9) and housing (1) is tangent, thereby is partitioned into airtight isolated high low pressure active chamber mutually.Fluid inlet and outlet on housing (1) is positioned at end partition at whole story body (4) both sides, is connected respectively with high low pressure active chamber.Power transmission on piston (8), (9) is completed by the live axle on a side rotor side cover (6), thereby has possessed basic structure and the groundwork key element of positive displacement pump (motor).Fig. 1 a～e has shown in embodiment of the present invention oil hydraulic pump that a piston (piston A) is from the process of the end-of-job of starting working successively, has also shown that passing through whole story end after another piston (piston B) power cut-off cuts off body and get back to job initiation end simultaneously.Fig. 1 d shows that end partition at whole story body (4) inner cylindrical surface cross section circular arc arc length is greater than the arc length that rotor pellet (5) cylindrical body cross section cylindrical circular arc is positioned at circular cross-section groove barbed portion, and it is reliable through out-of-date airtight partition all the time that Fig. 1 d, e demonstration end at the whole story cuts off the circular cross-section groove of body (4) on rotor pellet (5).On piston (8), (9) non-cylindrical surface, have logical oil groove (2), not only avoided entrap phenomenon, also make piston (8) or (9) pass through the state (as shown in Fig. 1 c) that only remains movement in a side active chamber therein when first and last end cuts off, avoided causing in mobile the extra variation of working chamber volume of living in, guaranteed any time in theory flow and drive shaft speed all remain strict linear proportional relation.Its rotor angular displacement/cylinder volume-variation relation is as shown in figure (5).Be particularly suitable for manufacture features such as (precisely linear with current kidney-shaped cam and elliptic gear formula structure flowmeter phase specific discharge, and unique simple in structure, easy to manufacture) cost are low of metering pump and flowmeter.Adopt logical tank structure can make hold gap between partition body (4) and piston (8) or (9) can be bordering on zero the whole story in transient process, reduce to greatest extent liquid flowing resistance and without the return space of work efficiency, its suction capacity is maximized.Fig. 1 e shows that the sector crosssection external arc arc length of piston is greater than 1/2nd of same radius circumference, and from Fig. 1 a, d, e, f, two pistons have been realized the seamless stable operation alternately continuing.As seen from Figure 2, connecting rod (10), (11) one end are fixedly connected with piston (8), (9), and the other end is hinged with multi-joint crank (12) by hinge pin (13), (14).Because overall structure needs, multi-joint crank (12) adopts loop configuration, multi-joint crank (12) is positioned on a side body end cap (3), can rotate along its inner side plane, it rotates the center of circle and rotor slewing circle equals connecting rod (10) apart from e in the heart, (11) effective active length e1, e2, multi-joint crank (12) is active length L1 effectively, L2 equals piston (8), (9) the distance J1 at rotation center and rotor center, J2, thereby (the rotor-side cover crank of Liang Zu mechanism combines respectively and manufactures with becoming a part with multi-joint crank section crank to have formed as shown in Figure 3 two groups of constant speed cross crank gears that consist of rotor side cover (7) and multi-joint (12) two connecting rods of isometric crank of crank (10) or (11), on Same Part, two-part position differs 180 °), due to piston (8), (9) with connecting rod (10), (11) be fixedly connected with, thereby realized piston as shown in Fig. 1 a～e around circle translation and passed through periodic duty.From Fig. 2 a, auxiliary connecting rod (20) is hinged by hinge pin (15) and multi-joint crank.Hinge pin (15) and hinge pin (13), (14) respectively differ 90 ° of phase angles, when connecting rod (10), (11) are during in illustrated dead center position, still can, by auxiliary connecting rod (20) transmission that continues, realize accessible continuous transmission.
By Fig. 1, Fig. 2, be also shown in, each component are all simple in structure, easy to manufacture, kernel component only needs the processing such as common turnning and milling mill, and without special equipment and frock, generally small-sized machine processing enterprise can directly go into operation, and amount of parts is few, so cost is low, and technical threshold is low.Therefore each rotatable parts structure or motion state can be accomplished full symmetric, can run up and friction, noise.Transmission device is by taking seal approach to open with working portion is isolated, and working medium and oiling agent no longer influence each other, and can be used for manufacturing water pump, food pump and chemical pump etc.In work, flow of fluid is smooth and easy without turbulent loss, so efficiency is high, can also be for the conveying of thick liquid and liquid class I liquid I.Because positive displacement pump (motor) has the advantages that efficiency is high, as shown in Figure 6, by adopting sheet material welding or cast structure, can realize large flow, alternative centrifugal pump is applied to large-scale water conservancy lift pump etc., can increase work efficiency, reduce energy consumption, save mass energy; Be applied to revolve the alternative water turbine of shifting piston-type hydraulic motors and carry out the utilization ratio that hydroelectric power can improve the energy; Alternative centrifugal fan is applied to dedusting negative-pressure air fan, can reduce the power of drive unit, thereby reduces energy consumption, can also form higher degree of vacuum simultaneously, increases filtrating equipment operating pressure differential, thereby increases wind flow.Can also two-way working, realize centrifugal pump can not the working state of realization, simplify the structure of some application centrifugal pump device, or change its working method, produce beyond thought effect.Therefore application surface is extremely wide.
As shown in accompanying drawing 4, Fig. 2 (a), the present invention also passes through at described piston (8), (9) outer cladding one deck sealing material (16), the whole story, end cut off the coated one deck sealing material (17) of body (4) outer surface, thereby had promoted the sealability of piston (8), (9) and end partition body at the whole story (4).By setting up seal ring (18), (19) of an odd-shaped cross section between the external cylindrical surface in rotor side cover (6), (7) and housing (1) inner cylindrical surface, sectional shape be by 3/4ths circle and two tangent with it, mutually vertical, the straightway that length equates with radius of a circle forms, straightway is positioned at housing (1) end face and rotor side cover (6), (7) external cylindrical surface place, solved the indeterminable sealing problem along the circumferential direction of conventional seals circle, thereby realized between all relevant moving elements gap-free sealed.
