Definitions
- a worm pump of the construction described above is made known by GB-A-2 029 514.
- This points including one driven by a drive axle helically wound eccentric screw rotor with constant circular cross section.
- the one in a stator room longitudinal elastic hoses are by means of end plates through the stator.
- openings are provided in the aforementioned plates.
- central openings that accommodate the recording serve a drive or rotational axis.
- the gap play or Fit between eccentric screw rotor and stator like this adjust that this is about twice the wall thickness of the corresponds to elastic hoses. Consequently, attack the Hoses running in the longitudinal direction to which can lead to unavoidable damage. Especially can be stretched, for example in connection with Aging effects can lead to tearing, not to be excluded.
- the invention is based on the technical problem Worm pump of the construction described above with regard Improve resistance and wear problems.
- the invention teaches to solve this technical problem in a generic screw pump for flowable Pump material that the stator chamber is longitudinal, partially cylindrical Stator wall sections and at least two between the Stator wall sections longitudinal cavities for the has resilient hoses disposed therein, and that the stator wall sections with a clearance to the Sum of eccentricity distance and cross section radius of the Eccentric screw rotor adapted radius.
- the invention is based on the knowledge that despite of the open, helical channel between the eccentric screw rotor and the partially cylindrical stator wall sections can achieve a promotional effect if the stator between the stator wall sections with longitudinal Cavities and hoses arranged in them is provided: between the longitudinal hoses and the helical circumferential areas of the Eccentric screw rotor creates cutting areas with Sealing lines used to generate lengthways spaced sealing areas of the hoses are used. Sealing areas and conveying spaces enclosed between them by rotating the eccentric screw rotor in the conveying direction moved so that the pumped material is conveyed.
- Auger pump multi-flow that is, for simultaneous Promotion of several, independent pump material flows suitable.
- the pumping material is conveyed in sections compressed hoses is basically known as Peristaltic pumps known from practice (see Ullmanns Encyclopedia of Technical Chemistry, 1973, Volume 3, page 169).
- a hose through several, along the Hose moving displacers such as rollers or Sliding shoes compressed.
- a multi-flow arrangement requires and is an increase in the number of these displacers constructively complex.
- the hoses while reducing their lifespan in the longitudinal direction stretched.
- the screw pump according to the invention produces on the other hand, no expansion of the hoses because of frictional forces between rotor and hose essentially only in the circumferential direction of the eccentric screw rotor act.
- the eccentric screw rotor not only with one, but with several gears. Due to the increase in the length of the pump stator Number of sealing areas can be the tightness of the Increase the screw pump and the achievable pressure.
- the Pump stator of the screw pump according to the invention can are basically made of any material. For The use of a has been gentle on the hoses elastic material with a hardness between 90 and 95 Shore A especially proven. Regarding an even and low pulsation running of the screw pump, it is from Advantage, cavities and hoses equidistant on the Distribute the circumference of the stator space.
- Another preferred embodiment lie to promote the same Hoses serving the goods to be pumped on each other in pairs opposite the circumference of the stator space, so that at one later merging of the streams does not equal pumped goods Pulsation occurs.
- Another preferred embodiment provides for hoses in the cavities different diameters are recordable. Hereby different amounts in the individual tubes are funded by Pumpgut. The ratio of the funded The quantity depends on the speed and gradient of the eccentric screw rotor and thus the total output independently, so that the device according to the invention be used especially for dosing and mixing tasks can, with the control of various individual pumps There is no change in the total output. It goes without saying that the depths and breadth of the cavities the different hose diameters can be adjusted.
- the device shown in the figures serves as a screw pump for flowable pump material.
- the necessary ones Units for drive, storage of the eccentric screw rotor as well as for the supply and removal of the pumped goods have been improved Clarity not shown.
- FIG. 1 shows hatched the circular cross section of the Eccentric screw rotor.
- the center 3 of the eccentric screw rotor points to the axis of rotation 4 Eccentricity distance e on.
- the pump stator 5 includes one Stator chamber 6, in which the eccentric screw rotor 2 as is rotatably arranged.
- a comparative 1 and 2 it can be seen that the stator space 6 longitudinally running, partially cylindrical stator wall sections 7 having.
- Fig. 2 shows a fitting game s between the Eccentric screw rotor 2 and the pump stator 5, through which allows wear-free operation of the two components becomes.
- the radius R of the partially cylindrical stator wall sections 7 is out of the sum with this fit s Cross-sectional radius r of the eccentric screw rotor 2 and Eccentricity adjusted e, as can be seen in Fig. 2.
- the Eccentricity e is 23% of the embodiment Eccentric screw rotor diameter. It can be seen that the Rotation axis 4 and the longitudinal axis 4 of the stator space 6 coincide and so far a central drive of the Eccentric screw rotor takes place.
- Fig. 2 shows four Cavities 8 in the stator chamber 6. These run as shown in FIG. 1 shows in the longitudinal direction between the Stator wall sections 7. In the cavities 8 are elastic hoses 9 arranged. The one shown The worm pump has four channels. The funding mechanism is in 1 can be seen well.
- the Sealing line between eccentric screw rotor 2 and hoses 9 runs in one of the pitch of the eccentric screw rotor 2 dependent angles to the longitudinal direction of the tubes 9.
- the eccentric screw rotor 2 shown is catchy, it can but can also be easily carried out in multiple courses.
- Hoses 9 are made of elastic rubber or plastic be made.
- the pump stator 5 Use of an elastic material with a hardness of 90 Up to 95 Shore A advantageous for protecting the hoses. in the the rest of the chemical resistance of the Eccentric screw rotor and pump stator material only low requirements, so that inexpensive materials can be used.
- Fig. 2 shows that the tubes 9th are distributed equidistantly around the circumference of the stator space.
- two different items to be pumped be promoted, so it is beneficial to low pulsation Convey each pump good in pairs on the circumference of the stator chamber 6 opposite hoses 9 use.
- the hoses 9 shown in Fig. 2 have the same diameter and promote the same Pump material flows. It is easy to see in Fig. 2 that the Diameter of the hoses can be changed easily can to increase the delivery rate of the individual hoses vary. In operation, the ratio of those in the Hoses 9 pumped material flows constant and from Total throughput or of speed and slope of the Eccentric screw rotor 2 be independent.
