Definitions
- the invention is concerned with the piston guide in Thick matter pumps, such as those used to pump viscous or almost solid substances such as sewage sludge or thickened sewage sludge or sludge can be used (cf. US-A 2,175,441, Miller).
- DE-A 37 42 938.8 proposes a piston pump for the media mentioned, which enables easy replacement of the wear part "delivery piston", which is done by two half-shells (designated 29) at the rear end of the cylinder -The bushing is arranged under tension and when loosening, make the front part of the piston (there designated 18) easily accessible.
- This solution has proven to be susceptible to failure in tough everyday operations because the delivery pipes can no longer be moved after long periods of operation and regular replacement of the delivery piston is made difficult.
- an asymmetrical movement of the delivery piston is addressed in the aforementioned disclosure of the prior art (cf. claim 13 there), this asymmetrical movement is made possible by a pressure control device and by sensors which influence the pure axial movement of the piston.
- US-A 2,175,441 shows improvements in slurry pumps which relate to increased tightness and improved contact of sealing rings made of abrasion-resistant rubber on a cylinder wall.
- the radially outer ring surfaces (the "lips" 23, 24 in Miller) of the relatively stiff, abrasion-resistant rubber rings (15, 16 in Miller) are followed by soft rubber rings (17, 18, in Miller), which lie radially inside the rigid rings pressed against the outside of the cylinder wall. Measures to compensate for tension or alignment tolerance of the piston rod movement are not proposed.
- the elastic storage can be doubled by two elastic bearings on the - seen in the radial direction - Inner surface and outer surface are provided (claim 3).
- the inner annular surface is preferably based on two axially spaced compensating bodies, such as O-rings (claim 4, Claim 5).
- the floating one radially outside Storage of a piston seal (claim 2) can by similar or the same (only in terms of diameter different) compensating bodies can be reached, whose axial distance may be less than the aforementioned axial Distance of the inner compensation body (claim 4, Claim 5).
- the holder of the floating piston body in Axial direction is made possible by two washers, one have a fixed axial distance from one another (claim 6).
- one of the Ring disks integral with a hollow cylindrical body so be connected that after its application to the piston rod the elastic compensating elements are arranged on it and then the annular piston body is pushed over it (Claim 7).
- a second one in the front Washer axially fixed against the base body (Claim 8) so that the annular piston body receives final floating storage.
- the unit at the front end of the piston rod is light exchangeable by loosening the nut, by removing the front washer and by pulling down the floating one Ring body. He can then provide new outer seals it can also be completely replaced. Likewise nut and front washer can be replaced if these have been heavily used by the company.
- the ring discs mentioned have an outer diameter, which is slightly smaller than the diameter dimension of the im Radial seals provided piston body (claim 12), can ensure that alignment and Tension tolerances of the piston rod compared to the Central axis of the cylinder no contact between the Ring discs and the cylinder liner are created.
- Figure 1 shows the front end of a piston rod 10, the central axis 100 is shown in phantom.
- An annular piston body 5 is floatingly mounted approximately concentrically around a section of the piston rod that is only slightly set back relative to the end face. The figure is shown partly in section (upper half) and in side view (lower half).
- FIG. 2 shows an overview of where the exemplary arrangement according to FIG. 1 is arranged in a thick matter feed pump.
- FIG. 2 where a partially cut thick matter feed pump 30 is shown.
- the central axis is designated 100, in it the piston rod 10 moves in a controlled manner by a hydraulic drive (not shown).
- a hydraulic drive not shown
- An exemplary delivery piston is drawn, which comes from the prior art.
- FIG. 1 the example shown in FIG. 1 of a floating mounting of the delivery piston on the piston rod 10 can be used.
- the piston runs in a cylinder liner 20, which can be a metallic sleeve of a coordinated cross-sectional dimension with a thin wall.
- a water box 40 is arranged at the rear end of the cylinder liner 20. It contains water for the lubrication of the hard chrome-plated cylinder barrel surfaces and for cooling purposes. It is also the place where the plunger is retracted when it is to be replaced.
- Valve 32 On the left edge of the picture is a flange connection in near the second valve 33 Central axis direction arranged on a conveyor pipe is flanged.
- Valves 32 and 33 work in push-pull, Valve 32 is open when the piston moves backwards moves, valve 33 is open when the piston moves moved forward. When the piston moves forward Valve 32 closed.
- the opening times of the valves can electronically via sensors or timers with the Axial movement of the piston rod 10 be coupled, the opening and Closing times can also overlap slightly.
- FIG. 2 A detail of Figure 2 - the pump head - is shown enlarged in Figure 1 .
- the delivery piston shown in FIG. 2 is a delivery piston solution according to the prior art, in which no "floating bearing" is provided, as is achieved in the example according to FIG. 1 .
- Figure 1 shows a cylinder piston which is arranged interchangeably at the front end of the piston rod 10 via a nut 9.
- the piston initially consists of three basic components 5; 6, 6a; 8, wherein the component 6, 6a forms an integral part - the piston base body. It has an approximately L-shaped cross-section - above the central axis 100 - and serves to receive the ring-shaped piston body 5, the inner opening of which is slightly larger in diameter than the outer diameter of the axial section 6a of the piston base body 6, 6a.
- the front-side mounting - corresponding to the rear axial holder 6 of the piston base body - takes over an annular disc 8 which is pressed against the base section 6a of the piston base body by means of the nut 9.
- a piston body 5 is held in the annular recess formed in this way between the two annular disks 6, 8 and the piston base body 6a, which has a smaller outside diameter. Its axial side sections can be spherical, but they can also be straight if they have a small amount of play compared to the washers 6 and 8.
- the piston body 5 is on its inner annular surface 5a axially spaced O-rings 7a, 7b supported, which in turn in annular grooves 7c and 7d are inserted so that they are still a protrude a little radially to match the inner mentioned Annular surface 5a of the piston body 5 to come into contact.
- Two further sealing elements can be provided on the circumference of the piston body 5 be.
- Pistons 5, 6, 6a and 8 with the elastic bearings Compensating bodies 7a, 7b, 3a, 3b.
- the piston rod 10 has a short front taper a thread 10b can be located.
- This taper creates a fit between piston base body 6, 6a and piston rod 10 annular shoulder 10a, on which the piston base body 6, 6a of stops on the face when it hits the piston rod 10 is plugged on.
- the piston base body is on the face 5 of which then also on the tapered front section of the piston rod 10 to be attached Washer 8 set in the axial direction.
