Embodiment
Pump (Fig. 1) comprises the housing 1 with end plate 2 and 3.Rotor 5 is installed in the housing 1 and is contained on the axle 4.In rotor 5, provide conduit 6, but the discharger 7 of axial motion is positioned at this conduit 6.This pump can comprise at least two and more dischargers 7.Provide the cylindrical slot (18 among Fig. 2) of annular in the end of rotor 5, it is relative with end plate 2 that this cylindrical slot is arranged to.The conduit 6 that holds discharger 7 is formed in the rotor 5, and like this, they are towards these annular cylindrical slot 18 openings, and forms recess 8 on the cylindrical surface of the inside of this cylindrical slot 18.In other words, in the end of rotor 5, provide circular groove 18, like this, it by in rotor 5, wherein be provided with the conduit 6 of discharger 7, the radial width of this circular cylindrical groove 18 is less than the radial width of discharger 7.In the pump of present embodiment shown in the figure, conduit 6 arrives the end of rotor 5, and forms recess 8 on the entire depth at it in the cylindrical surface of the inside of circular groove 18.But, in other pump embodiment, conduit 6 can not arrive the end of rotor 5, but at a certain distance.
Pump comprises dividing plate 9, and this dividing plate 9 makes injection space and suction space separately.(suction space links to each other with inlet hole, and inject the space and link to each other with exit orifice, for the sake of simplicity, not expression among the figure.) surface of dividing plate 9 and the internal surface sliding contact of circular cylindrical groove 18.Dividing plate 9 is installed on the end plate 2, and can form an integral body with this end plate.(in the embodiment of some pump, but dividing plate 9 can be the axial motion of fixing; And can interact with the device that this dividing plate is clipped on the rotor 5.) therefore, define the working room by the internal surface of circular groove 18 and the internal surface of end plate 2.
Pump comprises the mechanism that discharger 7 is set in the position to axial in the conduit 6 of rotor 5.In the pump of present embodiment, this mechanism is formed in the closing cam groove 10 in the inside cylindrical surface of housing 1.And each discharger 7 is equipped with push rod 11, and this push rod enters in this cam path 10, and with these cam path 10 sliding contacts.Cam path 10 is made like this, promptly is positioned at the equidistant place that the discharger 7 relative with dividing plate 9 ends all moves to rotor 5, and apart from a part of discharger 7 of dividing plate 9 certain distances pull out rotor 5 and with the internal surface sliding contact of end plate 2.
This pump also comprises a device, and this device will be positioned at the device that the cavity of both sides of the longitudinal relative end back of discharger 7 links to each other.In the pump of present embodiment, this device forms one group of conduit in each discharger 7, and this group conduit forms like this, that is, described conduit links to each other the cavity of the both sides of the longitudinal relative end back that is positioned at discharger 7.For the sake of simplicity, above-mentioned conduit does not illustrate in the drawings.But, the device that the longitudinal relative end back that is positioned at discharger 7 and the cavity on both sides are linked to each other also can be realized in many ways, for example adopts at the most approaching supporting described in the prior art of the present invention and distribution switchboard (or adopting a plurality of described devices).This supporting and distribution switchboard can be mounted to and can move along the longitudinal direction of rotor 5.
And, pump is designed so that the opposite end surface sliding contact of the end surfaces and the Sealing 12 of rotor 5, in the end surfaces of this rotor 5, provide the cylindrical slot 18 of annular, and the end surfaces of this rotor 5 is positioned at the not homonymy of circular cylindrical groove 18, the surface, opposite end of Sealing 12 is positioned on the internal surface of end plate 2, and can be integral with it.This can reduce fluid and leaks from the working room, and can reduce the wearing and tearing with the dividing plate end surfaces of rotor sliding contact, because bigger at the rotor and the contact area between the separator of pump.
In the pump of present embodiment, Sealing 12 forms two hollow cylinders, and is installed in the circular groove 13, and this circular groove 13 is made for the internal face of end plate 2 concentric.These hollow cylinders are mounted to and make their cylindrical surface respect to one another contact with the surface of dividing plate 9, and these hollow cylinders are located at the outside of the circular cylindrical groove (18 among Fig. 2) that forms in rotor 5 end surfaces.
This has simplified dividing plate 9 greatly and the manufacturing process of guide (especially, but the dividing plate and the variable displacement of axial motion are arranged in the present embodiment) has been installed.
Hollow cylinder is installed in the circular groove 13, and can be along the axial motion of rotor 5.This makes that this hollow cylinder can be with the axial motion campaign of rotor 5 (when this pump is equipped with when being used to make the appropriate device of this cylinder axial motion), and with its lasting contact.Therefore, in the vibration and axial motion process of rotor, also seal operation chamber stably, and can compensate for heat expansion and the wearing and tearing that cause by the friction of pump parts.Axially the device of cylinder motion forms like this: at least one passes conduit 14 and is formed in these hollow cylinders, and this conduit 14 extends to the circular groove 13 that this cylinder wherein is installed from the cylinder end facing to rotor always.By changing section area and the position of conduit 14 at place, cylinder end, can select the best use of power that described cylinder is clamped on the rotor 5, can optimize gap and leakage like this, thereby reduce the fretting wear of contact surface.
The second end of rotor 5 contacts with end plate 3, and groove 15 is formed in the internal face of end plate 3, can be installed in this groove 15 along at least one Sealing 16 of the axial-movement of rotor 5.In the pump of this specific embodiment, two Sealings 16 are installed in the end plate 3, and all pass conduit 17, and this conduit 17 extends to the circular groove 15 that wherein is provided with sealing part 16 from Sealing 16 ends facing to rotor always.
Fig. 2 has represented to have the broken-open perspective view of the rotor 5 of a discharger 7 and push rod 11, so that be illustrated in circular groove 18 and recess 8 on this rotor inner wall face.
The operation of this pump is as follows.
Start after this pump, when rotor 5 rotation, push rod 11 beginnings are slided the cam path 10 of closure in, so that along the running shaft to-and-fro motion of rotor 5, thereby discharger 7 are moved.Cam path 10 forms like this, and promptly rotor 5 whenever turns around, and the motion characteristics of discharger 7 are for to carry out following circulation: the discharger 7 relative with dividing plate 9 ends is drawn in the rotor 5, and can not move along the spin axis of rotor.After discharger 7 leaves dividing plate 9, it begins to be pulled out to from the conduit 6 of rotor 5 cavity 18 of column circular groove, slides (this recess 8 is additional guides of this discharger) along the surface of recess 8 then, then, at certain in a flash, discharger 7 contacts with the internal surface of end plate 2.Then, discharger 7 slides by the internal surface of its end along end plate 2, and not with respect to rotor 5 axial motions.When discharger 7 during near dividing plate 9, it begins to be pushed gradually in the rotor 5,, and is pushed in the rotor 5 up to the end through dividing plate 7 up to it.When sliding on the internal surface of end plate 2, discharger 7 makes injection space and the suction space in the column circular groove 18 separate.
In the general embodiment of this pump, but end plate 2 parts that discharger 7 slides thereon can form the separator (embodiment of variable delivery pump) of axial motion.
The working fluid that is defined between two adjacent dischargers 7 and is present in the conduit 6 begins to send the injection space to from suction space, in this conduit 6, be provided with this discharger 7, and low work nip territory and high workload nip territory result from this suction space and inject in the space, and this suction space is connected (having introduced this process in more detail in prior art patent) respectively with the injection space with exit orifice with inlet hole.
Working fluid will flow into suction space from injecting the space by the gap between separator.In column circular groove 18, inject the space and separate with suction space by the discharger 7 of the internal surface sliding contact of dividing plate 9 and end and end plate 2.
The pressure of the working fluid in injecting the space will make discharger 7 parts that are drawn into column circular groove 18 move towards suction space, thereby will make described discharger 7 crooked and distortion.But, the recess 8 that holds discharger 7 parts that are drawn in the column circular groove 18 will prevent the distortion and the bending of discharger 7.
The more favourable outcome that has recess 8 in the internal surface of column circular groove 18 is to have reduced backflow, and has reduced being used for the tolerance with the discharger 7 of the form fit of conduit 6; Discharger 7 is clipped on the surface of recess 8 by hydrodynamic pressure, thereby makes sealing better between the surface of discharger 7 and recess 8.And, because fluid is through having the part of various cross-sectional areas, also because at dividing plate 9 with hold between the surface of circular groove 18 of dividing plate 9 and form the oil-film wedge layer, so, will strengthen 9 that produce by dividing plate, in suction space with inject sealing between the space.
Also have, because the surface of circular groove 18 in the end surfaces of rotor 5 is to the radially restriction of working room, rotor eliminated the radial force that working fluid produces (opposite with the pump of many other types, wing pump for example, wherein, adopt double action pump to operate and reach this effect).The friction of the noise of therefore, the radial vibration of rotor, consequent rotor 5 rotations and unstability and fluid and the wall of restraint of labour chamber radially and the loss that causes owing to the friction of discharger 7 and these walls etc. all will reduce.
Lip-deep recess 8 at column circular groove 18 produces damping, and can control (can regulate by the size and the degree of depth of selecting suitable recess 8) to it.When discharger 7 during, can observe this damping in axial direction near the internal surface of the end plate 2 that limits the working room.When discharger near the internal surface of end plate 2 and when closing described recess 8 because working fluid mainly refluxes the high-pressure area along recess 8 from pumping chamber, therefore produce damping.At this moment, working fluid is compressed, and discharger 7 will be left, thereby hit suddenly on the internal surface of end plate 2 end that prevents this discharger 7.(this effect is especially outstanding in such pump embodiment, and in this pump embodiment, discharger 7 has projection (for the sake of simplicity and not shown) at it facing to end plate 2 and the end place that is positioned at recess.At this moment, this projection is at first closed recess 8, and is created in its inner enclosed space; Therefore, this damping depends on the size and dimension that this is protruding).
Damping can prevent to damage, and reduces the internal surface of end plate 2 and the wearing and tearing of the discharger 7 that contacts with this end plate; This makes the rotating speed of pump rotor 5 to increase.
Sealing 12 forms two hollow cylinders, is installed in the circular groove 13, and can be along with moving axially of may carrying out of rotor 5 and along the axial-movement of rotor 5, and permanent being clipped on the rotor.This clamping action is because the working fluid in the space below the injection space of pump flows into the end surfaces that is clipped in the Sealing 12 on the rotor 5 will be pushed Sealing 12 open from rotor.At this moment, the working fluid under the pressure will flow through conduit 14 from this space, and flow in the circular groove 13, thus the hydrodynamic pressure in balance conduit 14 and the circular groove 13.Because the whole zone of Sealing 12 all is in the working fluid pressure of circular groove 13, and in rotor-side, only pressure is arranged in zone effect near the injection space of pump, therefore, the best use of power that the Sealing 12 that forms cylinder is clipped on the rotor 5 can obtain in the position at place, Sealing 12 ends by selecting suitable cross sectional area and conduit 14.And, by circular groove 13 being linked to each other with throttle valve (illustrating in the drawings for the sake of simplicity and not) and flowing through the working fluid of this throttle valve, can optimize the space between the end surfaces of Sealing 12 and the rotor 5 that contacts with sealing part 12 by adjusting.
The operation of Sealing 16 and Sealing 12 are similar.
Should be known in that pump makes usually like this, promptly all be designed to can axial motion for all parts that contact with the end surfaces of rotor 5, and comprises that the end surfaces with rotor 5 carries out from the device that compresses, similar with the axial-movement devices of Sealing 12.
Also should illustrate, always the rotation of rotor is meant its rotation with respect to the housing of pump, and no matter what device this housing is installed on, so that rotor is rotated with respect to housing.In a lot of actual conditions of using pumps, the pump parts that are called housing can be installed on the running shaft of setter, and the pump parts that are called rotor can be installed on the framework of same device or on other running shaft.
