Description

Rotary machine

Technical field

The present invention relates to mechanical engineering, and can be used for the reversible machine that height forces down vibration, it can come work as motor and pump.Can use gas and liquid working fluid.

Background technique

In known adjustable rotary machine (UK 2207953), rotor is installed in the housing that includes an inlet and an outlet.Rotor has and holds the groove that radially slides valve.Described pump comprises and is used for valve is positioned at mechanism, the working room of rotor and the regulating element that can move radially.

As immediate prior art, the reversible adjusting pump (RU 2123602) that height forces down vibration comprises housing with entrance and exit and the rotor that is installed in enclosure interior.This rotor has the groove that is used for valve, and these valves can be along the rotatingshaft to-and-fro motion of rotor.(in addition, will use more general term " displacer (displacer) " to replace term " valve ").Described pump comprises: be installed in the mechanism of enclosure interior, it is used for the axially locating of displacer in rotor; The working room; And next door (partition), it separates suction space and pumping space with rotor, has therefore prevented the backflow of working fluid between them.Described next door is actually a kind of in the isolated component, and it prevents the backflow of working fluid between pump cavity, and is a kind of special case of next door, and this is because any pump of this design all has at least two next doors.

In this pump, working room's side is in the axial direction limited by the surface of rotor side surface (flank), and opposite side is limited by regulating element, wherein said rotor side surface and next door sliding contact also are called first side of rotor, and described regulating element is actually movably insulation component, that is, be mounted to first side and axially movable second next door facing to rotor.

The rotation pump of this design always has two groups of different elements, and they relative to each other rotate in opposite direction simultaneously with the magnitude of angular velocity that equates and around their common shaft.Usually their primary element differs from one another in each group, and these two element rotations relative to each other cause remaining pump element to rotate.One of these primary elements are commonly referred to rotor, and another is called stator (perhaps also being commonly referred to housing), and described rotation is with respect to this stator.

Term " rotor element " and " stator component " (below, be called " rotor " and " stator ") be relative, and depend on which element rotates with respect to another element.It should be noted that all rotations all think (unless mentioning other situations) with respect to the common shaft that rotates, and axially be meant the direction parallel with the common shaft of this rotation.

When rotor began to rotate with respect to stator, the combination that motion ground (cinematically) is attached to epitrochanterian pump element also began to rotate.Below these combination of elements and rotor self are called rotor unit.To not be called stator unit with respect to all the other pump elements and the stator self that stator rotates below with rotor.Always may distinguish the combination of the part of the formation pump working chamber in rotor unit and stator unit.The working room comprises suction space and pumping space, and also can distinguish such element in rotor unit and stator unit, that is, they are working portions of pump, and directly finishes the work that working fluid is transported to the pumping space from suction space.Suction and pumping space are the working spaces (they correspondingly are connected on the entrance and exit) of pump.In said pump, when rotor unit and stator unit finish they relatively rotate a circle time, the working portion of these unit also rotates with said units, the working portion of one of these unit is also done cyclical movement along their rotation common shaft at the moving circle of this unit revolution in addition, and the working portion of Unit second (another unit) is not done this cyclical movement.

Below will be wherein for the element of working portion is called rotor unit at the moving circle of rotor revolution along the pump unit that the common shaft that rotates is done periodic motion, and therefore its primary element will be called rotor.Below the remaining part of described unit is called stator unit, and therefore its primary element will be called stator.

Always it should be noted that the rotation of rotor will be with respect to stator, and go up so that the rotation of rotor with respect to stator to be provided no matter what device stator is installed in.

In many actual conditions that the present invention uses, the pump element that is called stator can be installed on the rotatingshaft of a certain device, and the pump element that is called rotor can be installed on the framework or another rotatingshaft of same device.Below, according to the above-mentioned meaning of these terms, all of rotor are rotated all with respect to stator.Rotate and directly finish the working portion that working fluid is transmitted the into work in the pumping space of pump with rotor and be commonly referred to displacer (following we will use this term), and the element of the stator unit that suction space and pumping space is separated with the element of rotor unit is called next door (following we will use this term).In adjustable pump, one in the next door is mounted to usually it can be moved with respect to rotor, and is called regulating element.Described suction space is connected on the inlet, and the pumping space is connected in the outlet.The pump that the moving circle of rotor revolution is finished the motion of displacer one-period always has at least two next doors, and these next doors separate suction space and pumping space.The pump in two cycles has the next door of double amount, and the pump in three cycles has next door of triple amount or the like.

For such pump, from rotor (in other words to the conveying capacity of having determined the moving circle of rotor revolution towards the difference the distance of the side in the next door of rotor, for these pumps, in the conveying capacity of having determined the moving circle of rotor revolution towards the axial distance between the side in the next door of rotor).

The rotary machine of being elected as prior art can not be at the feeding direction that does not make reversing working fluid under the reverse situation of rotor rotation during as pump work.When it is worked as oil hydraulic motor, do not allow do not make working fluid transmit the sense of rotation of reversing rotor under the reverse situation yet.

Summary of the invention

The objective of the invention is to widen function type scope, and improve their operating parameter for this rotary machine.

Solved this problem by designing such rotary machine, this machinery comprises the elements combination of stator unit and rotor unit, that is, it has: stator; Rotor with groove, the displacer that can move along the rotatingshaft of rotor is arranged in this groove; Be used to be provided with the mechanism of the relative axial position of displacer; The working room, it is limited by first side of rotor in the axial direction, and comprises suction space and pumping space; The next door, it is installed on the stator and faces toward first side of rotor; And can axially movable regulating element, it is installed on the stator and facing to first side (at same position) of rotor; Rotary machine according to the present invention has another working room, it is limited by second side of rotor in the axial direction, and himself comprise suction space and pumping space (side of displacer extends to these spaces), one next door and a regulating element, described next door and regulating element all are installed on the stator and face toward second side of rotor, described regulating element is mounted to it can be moved vertically, in addition, described regulating element is so positioned, promptly, the side perpendicular to the rotatingshaft of rotor facing to the next door is arranged in its side perpendicular to the rotatingshaft of rotor, wherein said next door is installed on the stator and faces toward first side of rotor, and the described next door of installing facing to second side of rotor is mounted to like this, promptly, the side perpendicular to the rotatingshaft of rotor facing to regulating element is arranged in its side perpendicular to the rotatingshaft of rotor, wherein said regulating element is installed on the stator and faces toward first side of rotor, and these regulating elements combine togather by the campaign-styled joint of rigidity, thereby the motion of a regulating element causes another regulating element motion, and the working space of two working rooms respect to one another in the axial direction is connected to each other by passage, and the mechanism design that is used to be provided with the relative axial position of displacer becomes to guarantee each regulating element and at least one displacer sliding contact.

Above-mentioned feature is introduced in the described rotary machine, can oppositely and at described machinery do not used under the situation of any special conversion equipment the feeding direction of reversing working fluid during as pump work in the rotation that does not make rotor.When described rotary machine is worked as oil hydraulic motor, can not reverse under the situation of feeding direction of working fluid and make the rotation of rotor reverse.

In addition, need be applied on the regulating element active force with the control rotary machine and no longer depend on working pressure in this system, and the variation of the pressure that is caused by the irregular load of pump in this system can't be passed to the mechanism of displacer axially locating and transmit regulon by working fluid.This allows to break away from the hydraulic actuator in the regulon, and reduces the control time of rotary machine.This relative positioning to regulating element and next door allows this rotary machine to reverse the feeding direction of working fluid by the mechanism that only uses one group of displacer, to be used to be provided with their relative axial position, and allows the perfectly balanced rotor from acting on working fluid pressure on the rotor side surface.

In addition, in the specific embodiment of rotary machine, for rotor being removed the radial pressure of working fluid, and the radial vibration of minimizing rotor and the noise that causes by these vibrations, and the fluid friction of minimizing on the wall that radially limits the working room, can radially limit two working rooms by the surface of the circular groove in the opposite flank that is located at rotor, thereby they pass the passage in the rotor, and displacer is positioned at wherein and described passage forms recess therein by intersecting with the internal surface of circular groove.In other words, they pass the hole of rotor thereby circular groove is positioned at the rotor side surface place, and displacer is arranged in the width of the radial width of described hole and ring-shaped cylinder groove less than displacer.The bottom surface of first circular groove is actually first side of rotor, and the bottom surface of second groove is second side of rotor.

Introduce all above-mentioned combination of features in the rotary machine and widened that it is functional, that is: allow under the situation of the sense of rotation that does not change rotor, to make the transmission of working fluid reverse when this rotary machine during as pump work; Allow when this rotary machine is worked as oil hydraulic motor, under the situation that the feeding direction of working fluid is fixed, make the rotation of rotor reverse; Allow to increase control rate, allow to be independent of the working pressure in the system and obtain constant regulating effect, allow simplified design, and allow to increase in fact the resistance for pressure jump in the system, described rotary machine is connected in this system.

The rotary machine of the embodiment of the invention (Fig. 1) comprises the housing (stator) 1 with end cap 2 and 3.Rotor 5 be installed in the housing 1 the axle 4 on.Generate hole 6 by rotor 5, can be positioned at wherein by axially movable displacer 7.Has the circular groove 8 that passes hole 6 facing to the end cap 2 and the side of rotor 5 that is called as first side of rotor 5.Rotor 5 has similar circular groove 9 facing to the side of end cap 3 simultaneously, and this circular groove 9 manufactures and also passes hole 6.

Circular groove

8 and 9 forms and makes hole 6 form recess 10 in their inner peripheral surface.This rotary machine comprises that next door 11 and can axially movable regulating element 12, its median septum 11 are installed on the end cap 2 facing to first side of rotor 5, and regulating element 12 is installed on the same end cap 2 facing to the same side of rotor 5.The bottom surface sliding contact of the side in next door 11 and circular groove 8.

This circular groove 8 defines first working room with end cap 2.Next door 11 and regulating element 12 are divided into suction space 13 and pumping space 14 (Fig. 6) with this working room.Suction space 13 is connected on the inlet 15, and pumping space 14 correspondingly is connected in the outlet 16.Described rotary machine has next door 17 (Fig. 2) and can axially movable regulating element 18, and its median septum 17 is installed on the end cap 3 facing to second side of rotor 5, and regulating element 18 is installed on the same end cap 3 facing to the same side of rotor 5.The bottom surface sliding contact of the side in next door 17 and circular groove 9.This circular groove 9 defines another working room with end cap 3.Next door 17 and regulating element 18 are divided into suction space 19 and pumping space 20 (Fig. 2) with this another working room.Next door 17 is mounted to and makes its side towards second side of rotor 5 be positioned to the side facing to regulating element 12, and the side of this regulating element 12 is mounted to first side facing to rotor 5.And regulating element 18 is mounted to and makes its side towards second side of rotor 5 be positioned to the side facing to next door 11, and the side in this next door 11 is facing to first side of rotor 5.The suction space 19 (Fig. 2) of this another working room is connected on the pumping space 14 (Fig. 6) of first working room by passage 21, and pumping space 20 (Fig. 2) is connected on the pumping space 13 (Fig. 6) by passage 22.These grooves pass housing 1, but in general embodiment of the present invention, they are formed in rotor and the displacer, but importantly these grooves link together the relative chamber of rotary machine.

This rotary machine comprises the mechanism of axially locating displacer 7, and this mechanism forms and guarantees sliding contact between at least one displacer and each regulating element 12 and 18.Make the mechanism that is used for the axially locating displacer by hollow circuit cylinder, and it is mounted to and can moves vertically around rotor 5.

On the internal surface of this hollow circuit cylinder, be formed with the curved slot 24 of sealing, thereby its limiting bending the relative axial position of displacer 7.In addition, each displacer 7 is provided with follower 25.These followers 25 enter in the curved slot 24 of sealing.The curved slot 24 of sealing is made the contacts side surfaces that makes facing at least one displacer 7 with the regulating element 12 of the side of regulating element 12, and the contacts side surfaces of at least one displacer 7 that is provided with facing to the side of regulating element 18 and regulating element 18.

In addition, regulating

element

12 and 18 and hollow circuit cylinder 23 combine by pull-type pin 26, thereby the axial motion of pull-type pin 26 cause regulating element 12 with 18 to the similar motion of hollow circuit cylinder 23.

As the rotary machine of pump in the following manner.

At first, pull-type pin 26 is located such that regulating element 12 and regulating element 18 are positioned at and equidistant place, the side of rotor 5, and they also are positioned at the place, neutral position facing to rotor 5 and hollow circuit cylinder 23.Based on this, pull-type pin 26 combines with them on demand.

When rotor 5 begins to rotate, the follower 25 of displacer 7 begins to slip over the surface of the curved slot 24 of sealing, and displacer 7 beginnings are along the rotatingshaft to-and-fro motion of rotor.The curved slot 24 of sealing is made and made whenever the turn around motion of each displacer 7 of rotor 5 have following periodic characteristic: the displacer 7 that contact with the side slip of regulating element 12 at the starting point place begins towards the next door 11 and slips over its side, and while next door 11 separates suction space 13 and pumping space 14 in first working room.Along with the further rotation of rotor 5, at a time displacer 7 begins to enter in the rotor 5, and stops suction space 13 and pumping space 14 are separated, and, unclamps the sliding contact of itself and regulating element 12 that is.

But slip over the side of regulating element 9 simultaneously immediately following thereafter displacer 7, so that suction space 13 and pumping space 14 are separated.Be contained between the two adjacent displacers 7 and begin to move on to pumping space 14 from suction space 13 at the working fluid of groove 6 (these displacers 7 are arranged in wherein), displacer 7 arrives pumping spaces 14 when rotor 5 rotates.

Along with the further rotation of rotor 5, displacer 7 is crossed next door 11 and is begun to arrive regulating element 12 once more.Then, at a time, displacer 7 by himself the side once more with the contacts side surfaces of regulating element 12, and as the zero hour, begin to slip over suction space 13 and pumping space 14 separate as described in the side.

Operation cycle in another working room much at one, difference only is to cross next door 17 with the displacer 7 of regulating element 12 sliding contacts at synchronization, then when displacer 7 is crossed next door 11, it and regulating element 18 sliding contacts that suction space 19 and pumping space 20 are separated.The suction space 19 of this another working room faces toward the pumping space 14 of first working room simultaneously, and pumping space 20 is correspondingly facing to suction space 13.Because suction space 19 is connected on the pumping space 14 by passage 21, pumping space 20 is connected on the suction space 13 by passage 22, and regulating

element

12 and 18 is positioned at the place, neutral position, does not therefore have working fluid to flow through inlet 15 and outlet 16.This situation why occurs and be because the amount of working fluid that enters in the pumping space 14 equates with the amount of working fluid that comes out from suction space 19 (these spaces link together by passage 21), and the amount of working fluid that comes out from suction space 13 equates with amount of working fluid in entering pumping space 20 (these spaces link together by passage 22).

When regulating element 12 moves to its stroke (end) when end by pull-type pin 26 from rotor 5, hollow circuit cylinder 23 and regulating element 18 also move along equidirectional.Skid off the axial length identical with the displacer 7 of the side slip of regulating element 12 contact from rotor 5, and the displacer 7 that contacts with the side slip of regulating element 18 slips into correspondingly in the rotor 5 with regulating element 12.

The working fluid that passes to pumping space 14 from suction space 13 increases, and the working fluid that enters from suction space 19 with and the amount that flows to pumping space 20 reduce, so working fluid begins to pump in the

outlet

16 and 15 flow out from entering the mouth.In order to make the working fluid stream in rotary machine reverse, pull-type pin 26 must move to another extreme position, at this place's regulating element 18 apart from rotor 5 farthest.When regulating element 18 was positioned at this position, working fluid stream was reversed, and working fluid begins now to be pumped back in the inlet 15 and from exporting 16 and flows out.

It should be noted that when regulating

element

12 and 18 is positioned at this limit position this rotary machine comes work with the upwards of movement of maximum with different working fluid pumping directions.When regulating

element

12 and 18 when the neutral position, the upwards of movement of this rotary machine reduces to zero, and begins once more to increase when regulating

element

12 and 18 is crossed this neutral position, but the pumping direction of while working fluid is reversed.

Interconnect by passage owing to be positioned at same axial working room respect to one another, so the working pressure in them is equal and pressure that acted on the rotor 5 by these working rooms is balanced fully.When this rotary machine is worked as oil hydraulic motor, can change the rotational velocity and the direction of rotor 5 by locating pull-type pin 26 in the mode similar to other reversible rotary machines.
