Eccentrie helical totorpump is applied to different fields, such as, be applied in agricultural, chemical industry, food industry and paper-making industry.Eccentrie helical totorpump belongs to the classification of rotary volume pump and forms primarily of rotor and stator except driving mechanism.The feature of the helical, rotor of eccentrie helical totorpump is large pitch (Steigung), large height of thread and little minor diameter of thread.A stator pitch more than rotor and stator has the double of the pitch length of rotor.Form conveying space between the stator and the rotor, this conveying space to move and fed sheet of a media can be transported this conveying space continuously from inlet side to outlet side.
The rotor of eccentrie helical totorpump is made up of high-abrasive material, such as steel usually.And stator is made up of elastic material, such as rubber usually.But by the known stator be made up of a kind of material in metal and/or plastics or their composite material of prior art.
Correspondingly determine the size of all parts of eccentrie helical totorpump for each conveying task or it is designed.Such as determine transmission power and by stators and rotators size and configuration accessible pressure.Therefore such as design and structure driving mechanism in an identical manner in the eccentrie helical totorpump of two complete different application.Particularly eccentrie helical totorpump can realize different transmission powers and pressure when the revolution of rotor is identical.Be change to the requirement of eccentrie helical totorpump, improved owing to such as needing the transmission power reached and this pump is no longer suitable to this, therefore only can change eccentrie helical totorpump, because transform usual hell to pay.
Such as, US 2,483,370 discloses a kind of eccentrie helical totorpump with multiple cylinder, and these cylinders to be combined in regularly in a housing and to be also furnished with rotor speed changer in this housing.Advantageously known, pump only needs single sealed department due to its mode of structure.Pump only has an outlet (exhaust port 29), so be immutable to all conveyor module pressure.Conveyor module is subject to eccentricity impact, and this eccentricity needs to be compensated by the speed changer of inside, and this causes quantity delivered to be restricted and pump is subject to high wear.Pump only has an entrance (entry port 28), and this entrance only for a kind of fed sheet of a media, and only can change module with relative high expense in couples due to compact structure form and special driving device.
Also known a kind of eccentrie helical totorpump (US 5,820,354) with the pump stage of at least two series connection.The pump duty of second pump is less than the pump duty of first pump.This mode of execution is by cooling with the cooling equipment be arranged between pump stage (cooling system 55) compensation achieving fed sheet of a media to fed sheet of a media.Its flow is made to reduce and less pump stage can connected thereafter by the cooling effect be applied on fed sheet of a media.Therefore the throughput direction of the fed sheet of a media of pump-unit and entrance and outlet are all unmodifiable.
WO2009/038473A1 discloses the eccentrie helical totorpump that one has two pump sections (Pa, Pb), wherein surrounded the pump rotor of at least one inside by the pump rotor of at least one outside, wherein with different rotor speed driven pump sections (Pa, Pb).This pump has an entrance (inlet flange 21) and an outlet (outlet(discharge) flange 28) for conveying fluid.
But can expect to provide a kind of pump, this pump can simply and be applicable to carry task accordingly with low expense.In addition, carry while needing to realize different product by this pump, and do not need multiple independent pump or pump-unit for this reason.And the requirement of the parts relevant to conveying significantly improved pump is not needed relative to traditional eccentrie helical totorpump.
But known eccentrie helical totorpump or eccentric screw pumping system are all not enough to meet this requirement.

According to the present invention, this object is achieved by providing a kind of eccentrie helical totorpump, this eccentrie helical totorpump is configured with modular transporting system, this eccentrie helical totorpump comprises the conveyor module that at least two comprise rotor and stator respectively, wherein this conveyor module is coupled to each other and only configures a driving mechanism for transporting system, and wherein transporting system has more than one entrance and/or outlet for fed sheet of a media, or there is at least one modular percolation housing.
Conveyor module is counted as to this rotor-stator assembly, transports fed sheet of a media by this rotor-stator assembly.Different products can be carried by eccentrie helical totorpump according to the present invention and the more than one conveyor module of employing simultaneously, but also can transport the like products from different source simultaneously.In addition the accessible pressure of pump is improve by the multiple conveyor module of series connection.Be coupled to each other conveyor module for this reason, make to need an only driving mechanism to drive these conveyor modules.
To this, the present invention, from this consideration, can realize carrying mating of task with each by the transporting system of modular especially simply.To this, should for the entrance and exit of fed sheet of a media and the quantity of conveyor module substantially can at random expand and combine.The demand of pump and user can be effectively made to match by the modular system provided like this.
This is achieved by making at least two conveyor modules be coupled to each other.Conveyor module comprises stators and rotators respectively, and its rotor is only driven by a driving mechanism.To this, rotor is interconnected the power produced when being delivered in eccentrie helical totorpump running, the torsion particularly produced by driving mechanism.To this preferably, conveyor module is coupled to each other, makes the phase difference realizing 180 ° between the vibration caused by the respective rotor of conveyor module and the pressure surge relevant to corner.Because the frequency of vibration is identical, owing to only using a drive system, so it is minimum to make vibration be reduced to.
Preferably, conveyor module is coupled to each other by suction casing, pressure housing or percolation housing.Such advantage is, can setting-up eccentricity screw pump independently according to conveying task.To this, suction casing and pressure housing are provided with pipe joint and are connected for conveyance conduit.Thus, intake line can be connected on suction casing and pressure piping is connected on pressure housing.
By combining suitably and selecting housing, eccentrie helical totorpump can be changed according to corresponding conveying task in other words with the allotment of relatively little expense.Conveyor module is selectively coupled to each other with pressure housing, suction casing or percolation housing, is provided with pressure housing or suction casing necessarily in other words.In addition, conveyor module can be embodied as various, makes the transmission power of the conveyor module when the speed of rotor is identical different.If carry different products, so certain mixed proportion can be set.
For the rotor of conveyor module configuration is coupled to each other in enclosure interior preferably by the link of rigidity, make it possible to continuously and transmit losslessly be applied to epitrochanterian power by driving mechanism.Rotor can by the known arbitrary rigidity of prior art or the link that is configured to rigidity connect, this link should be applicable to transmitting torque or transmitting torque and axial force according to service condition.Such as advise it being that material fit as welding, bonding or brazing connects or power as connected in be spirally connected, clamp connection or pin is connected and/or form fit connection at this.But rotor also can be interconnected by movable joint naturally.
In one preferred embodiment, rotor is releasably interconnected.Simplify thus and improve the installation and removal of conveyor module.Make it possible to thus reequip according to eccentrie helical totorpump of the present invention according to the conveying task of change.
Specify in another embodiment, at least two conveyor modules rotor single type construct.Because there is no link position, so this structural type is particularly well suited to carry such as abrasive media and corrosive medium.When mounted, housing and stator are pulled on the rotor of single type.In the mode of execution that this is special, stator is counted as conveyor module, and conveyor module just realizes its function together with corresponding rotor section after mounting.
Eccentrie helical totorpump is preferably configured as, and the axial force F that the direction towards driving mechanism acts on goes to zero or is at least lowered.This is achieved by making two conveyor modules carry in the opposite direction when the rotating speed of rotor is identical and sense of rotation is identical.To this conveyor module, there is contrary pitch.In the eccentrie helical totorpump with such as two conveyor modules, one of them conveyor module has left handed pitch and another conveyor module has right-hand pitch.Between eccentrie helical totorpump on-stream period, the axial force that each conveyor module produces respectively acts in the opposite direction and almost entirely offsets when using conveyor module of the same race.When not considering different pitch, the mode of execution referring to the determination of delivery element of the same race and the size determined.So the axial force caused by driving side goes to zero, so the high bearing element of the cost be substantially made up of driver part and the pump case with pipe joint of such as driving mechanism can be replaced by the bearing element of cost advantages.Result significantly reduces the total load of driving mechanism.
Particularly preferably, conveyor module tandem arrangement in described eccentrie helical totorpump.Can implement especially simply thus from driving mechanism to multiple rotor or an epitrochanterian moment of torsion transmission.Construct with such as making rotor single type as stated like that and be also fine.Therefore in this embodiment an only rotor is needed for all delivery elements of eccentrie helical totorpump.
In another preferred configuration mode, two adjacent conveyor modules are coupled to each other by percolation housing and are disposed for identical throughput direction.Be identical to this pitch in two conveyor modules, preferably, conveyor module has left handed pitch.Namely product is transported in the first conveyor module, towards a direction is carried through percolation housing and the second conveyor module by the pipe joint that enters of pump case.Because each conveyor module is a pressure level, produced pressure can be improved by the conveyor module of multiple series connection.
In addition can advantageously, two adjacent conveyor modules are coupled to each other by suction casing or pressure housing, and wherein conveyor module is disposed for reciprocal throughput direction.Different to this pitch in two conveyor modules.Eccentrie helical totorpump can comprise first conveyor module with left handed pitch and second conveyor module with right-hand pitch thus, and two conveyor modules are coupled to each other by pressure housing, and fed sheet of a media is carried towards pressure housing through conveyor module thus.In this second embodiment, eccentrie helical totorpump can comprise first conveyor module with right-hand pitch and second conveyor module with left handed pitch, wherein two conveyor modules are connected by suction casing, suck fed sheet of a media thus and carry fed sheet of a media in the opposite direction by conveyor module.
In a favourable design proposal, eccentrie helical totorpump only comprises two conveyor modules.Even if use only two conveyor modules, also eccentrie helical totorpump can be configured, the form and this eccentrie helical totorpump is of compact construction thus according to the corresponding demand to conveying task.
Eccentrie helical totorpump such as can be configured to, and makes it achieve double transmission power when rotating speed is identical with sense of rotation when constant identical pressure compared to traditional eccentrie helical totorpump.To this, the first conveyor module connected with driving mechanism has left handed pitch, and the second conveyor module of series connection has right-hand pitch.Two conveyor modules are coupled to each other via pressure housing.Second conveyor module has suction casing in its end opposite with pressure housing.As in traditional eccentrie helical totorpump, suck fed sheet of a media by the suction pipe joint on pump case, but also suck fed sheet of a media by the suction pipe joint on suction casing extraly here.So under pump operating condition, fed sheet of a media is carried from both sides towards pressure housing and is exported via the pressure connection pressure housing.Also different fed sheet of a media can be carried by this way.A kind of fed sheet of a media or multiple fed sheet of a media are flocked together by this, wherein by selecting conveyor module adjustable mixed proportion suitably.
But the configuration of eccentrie helical totorpump also can realize double pressure when single as when the transmission power identical with traditional eccentrie helical totorpump.To this, eccentrie helical totorpump is configured with the conveyor module that two have identical pitch, preferably left handed pitch.Two conveyor modules are coupled to each other via percolation module.Second conveyor module has pressure housing on the end that it is opposite with percolation housing.In this flexible program, suck fed sheet of a media by the suction pipe joint of pump case, and by the first conveyor module, percolation housing and the second conveyor module towards the pressure housing conveying fed sheet of a media being provided with pressure connection.
In another flexible program, eccentrie helical totorpump comprises four conveyor modules altogether.According to configuration, the quantity delivered of four times can be realized relative to traditional eccentrie helical totorpump when pressure is constant, or realizes double quantity delivered when double pressure thus.
In order to realize the quantity delivered of four times, have two conveyor modules with different pitch to be coupled to each other via pressure housing respectively, two conveyor modules so formed are to being coupled to each other via suction casing again.Another suction casing is arranged in the end opposite with driving mechanism of eccentrie helical totorpump.Thus by fed sheet of a media are carried in three suction pipe joints and two pressure connections altogether.From the first conveyor module to the 4th conveyor module, conveyor module preferably has left-handed-d-l-right-hand pitch.
Except the preferred implementation that the wherein pumping system being configured with the eccentrie helical totorpump of four conveyor modules altogether comprises two suction casings and two pressure housings, in the design proposal that another is favourable, conveyor module is coupled to each other via a suction casing, two percolation housings and a pressure housing.Have two conveyor modules with identical pitch to be coupled to each other via percolation housing respectively, two conveyor modules so formed are to being coupled to each other via pressure housing again.Suction casing is arranged in the end opposite with driving mechanism of eccentrie helical totorpump.Conveyor module preferably has left-handed-left-handed-dextrorotation-right-hand pitch.
Preferably, eccentrie helical totorpump has the device for mixing connected with rotor in the attachment areas of conveyor module.One or more fed sheet of a media can be mixed thus in transport process.Especially, the advantage of this device is, make two kinds of different products, such as wherein a kind of product via the first suction casing and another kind of product be introduced in eccentrie helical totorpump via the second suction casing.In order to special product mix effectively, directly connect with rotor in the inside of pressure housing for the device arrangements that mixes.So do not need to drive separately.
According to a preferred expansion scheme, casing structure becomes substantially the same.Particularly suction casing and pressure housing are identical and limit by means of only its application type.Unlike this, percolation housing is preferably made up of suction casing or pressure housing, and wherein suction pipe joint or pressure connection are provided with fastening device.Such as this fastening device can be configured to blank flange, and this blank flange is fixed on housing pipe joint via flange connector.
The advantage realized by the present invention particularly, can by the only conveying of pumping system realization to the different fed sheet of a media be under predetermined certain mixed proportion condition.To this conveyor module by some and coupling device and carry out selection to it and enable pumping system mate conveying task especially simply.Because in eccentrie helical totorpump, quantity delivered and transporting velocity are determined by the geometrical shape of various key element, such as rotor and stator and pitch and affected by it, so can arrange quantity delivered especially simply by modular pump structure.By the mixed proportion using the conveyor module with different transmission powers can affect fed sheet of a media.Also escapable cost.Because do not need coupling rod and movable joint according to modular construction that is of the present invention, eccentrie helical totorpump and make the quantity of the moving element in fed sheet of a media keep thus relative few, so cost of energy and cost of material can be saved.Thus reduce the efficiency of pump and the frictional force that has a negative impact its working life.Conveyor module can be arranged to, and axial force is almost entirely cancelled.Reverse by making the sense of rotation of rotor and can change throughput direction.
Another advantage is, needs the only sealing system on the suction side of drive system and needs to safeguard this.Such as by eccentrie helical totorpump according to the present invention is used as so-called submersible pump can when the identical boring in other words of pipe diameter or bunghole identical realize the quantity delivered of twice.

Fig. 2 shows the eccentrie helical totorpump 2 with the conveyor module 4,6 that two are connected by pressure housing 16.First conveyor module 4 has left handed pitch L and the second conveyor module 6 has right-hand pitch R.Rotor 10 is interconnected by the joiner 34 of rigidity.The end opposite with driving mechanism 14 of eccentrie helical totorpump 2 is furnished with the suction casing 36 being provided with suction pipe joint 24.As in the eccentrie helical totorpump 2 shown in Fig. 1, pump case 22 has another suction pipe joint 24.
Due to conveyor module 4,6 different left-handed-right-hand pitch L, R make to be arranged in housing on the end of eccentrie helical totorpump 2 as suction casing 36.Therefore, fed sheet of a media to be transported in pressure housing 16 by two suction pipe joints 24 and to be transferred by pressure connection 18.Although the sense of rotation of the rotor 10 driven by common driving mechanism 14 is identical, fed sheet of a media is transferred in the opposite direction.This causes the axial force that produces when eccentrie helical totorpump 2 operates and is applied to the axial force adverse effect on rotor 10, and on the bearing making to be applied to driving mechanism 14 thus, caused power goes to zero or is at least minimized.To this, the joiner 34 for rotor 10 is designed so that this joiner can bear produced pulling force.Make live axle 30, movable joint 28 and bearing 32 bear less load thus in an advantageous manner, this causes less wearing and tearing.Can also correspondingly with the size of the component of the mode determination eccentrie helical totorpump 2 of cost advantages.In pressure housing 16, for the device arrangements that mixes in the region of joiner 34, this device connects with rotor and is configured to agitating element 37.Because conveyor module 4,6 is in parallel in this embodiment, so achieve double transmission power compared with traditional eccentrie helical totorpump.
As interchangeable unshowned mode of execution here in the example of figure 2, rotor 10 also can single-piece ground structure.Therefore the desirable joiner 34 that disappears.To this, rotor 10 has two sections for conveyor module 4,6.There is first section of left handed pitch L and there is second section of right-hand pitch R.
But Fig. 3 shows the eccentrie helical totorpump 2 with another driving mechanism 14 as shown in Figure 2.Driving mechanism has balance joiner 33 for transferring torque on rotor.Because the compact structure form of driving mechanism 14 almost entirely compensates the structural type of the prolongation of eccentrie helical totorpump 2 by the conveyor module 4,6 of series connection.
Fig. 4 shows the eccentrie helical totorpump 2 with four conveyor modules 4,6,38,40 altogether, two conveyor modules that the mode of execution being wherein similar to Fig. 2 is coupled to each other by pressure housing 16 are coupled to each other by suction casing 36, make the conveyor module 4,6,38,40 of transporting system from driving mechanism 14, have left-handed-d-l-right-hand pitch.The suction casing 36 with suction pipe joint 24 is arranged in the end opposite with driving mechanism 14 of eccentrie helical totorpump 2.Rotor 10 is interconnected by the joiner 34 of rigidity.Fed sheet of a media is transferred via three suction pipe joints 24 and two pressure connections 18 altogether.Because four conveyor modules 4,6,38,40 are in parallel in this embodiment, so achieve the transmission power of four times compared with traditional eccentrie helical totorpump.Identical with the quantity of the conveyor module 4,6,38,40 with right-hand pitch owing to having left handed pitch, the caused power be applied on the bearing of driving mechanism 14 goes to zero or is at least reduced.
Fig. 5 shows another alternative mode of execution with four conveyor modules 4,6,38,40 altogether.Have respectively in this embodiment two via percolation housing 12 be coupled to each other and the conveyor module pair of series connection, the first conveyor module be namely coupled to each other by pressure housing 16 to the 4,6 and second conveyor module to 38,40 pressure housings.The conveyor module of series connection has different pitch to 4,6 and 38,40, and thus transporting system comprises the conveyor module 4,6,38,40 altogether with left-handed-left-handed-dextrorotation-right-hand pitch.
Between eccentrie helical totorpump 2 on-stream period, be transferred away by sucking fed sheet of a media with the suction pipe joint 24 on pump case 22 and pass through an only pressure connection 18 on suction casing 36.Because have two conveyor module series connection in this embodiment respectively, and form thus two conveyor modules are to being connected in parallel, and thus achieve the transmission power double relative to traditional eccentrie helical totorpump and double pressure.Because the conveyor module 4,6 with left handed pitch is identical with the quantity of the conveyor module 38,40 with right-hand pitch, the caused power be applied on the bearing of driving mechanism 14 goes to zero or is at least lowered.
Fig. 6 shows by the known assembly with the identical traditional eccentrie helical totorpump 42 of multiple structure of prior art for comparing.That sees in fed sheet of a media flowing trend as indicated by dashed line is the same, and all four eccentrie helical totorpumps 42 are all in parallel, to realize the transmission power relative to simple eccentrie helical totorpump four times.Compared with the eccentrie helical totorpump 2 of modular according to the present invention, by the known assembly of prior art shortcoming especially, the energy requirement operated for making pump is large, manufacture cost and maintenance cost high and take up room large.
The pressure housing 16 that each eccentrie helical totorpump in four eccentrie helical totorpumps 42 comprises driving mechanism 14, rotor-stator assembly 44 respectively and is arranged on the end opposite with driving mechanism 14, this pressure housing is provided with pressure connection 18.Suck fed sheet of a media by the suction pipe joint 24 on pump case 22 and direction towards pressure housing 16 is carried, from this pressure housing, fed sheet of a media is transported to here in unshowned pressure piping by pressure connection 18.
According to device of the present invention specially for can flexible Application and the eccentrie helical totorpump 2 of cost and consumption can be saved by it.By simple especially modular, can, according to the quantity of suitable conveyor module 4,6,38,40 and housing 16,36 and selection, eccentrie helical totorpump 2 can be matched with corresponding conveying task.This is only needed to a driving mechanism 14, this is especially retentively relative little with maintenance requirements by energy requirement.By alternately arrange have different pitch L, R conveyor module can also thus reducing effect to the axial force on the bearing of eccentrie helical totorpump.
