Definitions
- the invention relates to a piston rod seal for an insulating cylinder of an electrostatic coating plant and a corresponding operating method according to the independent claims.
- DE 10 2005 048 223 A1 discloses a painting installation in which a paint store is connected via an insulation cylinder to a paint dispenser arranged downstream, the paint dispenser metering the paint to be applied in a controlled manner and feeding it to a rotary atomizer or other application device.
- the insulation cylinder in this case allows electrical isolation of the paint dosing relative to the paint reservoir. This is advantageous because the Lackdosierer is usually at high voltage potential in an electrostatic painting process, while the paint reservoir electrically insulated paint storage is at ground potential and therefore can be refilled during the painting process. For electrical insulation in the
- Isolation cylinder located paint residues of a Abstreifkolben of the inner wall of the insulation cylinder to produce the required dielectric strength.
- the stripping piston is in this case attached to one end of a piston rod which is displaceably mounted in a piston rod guide and carries at its other end a pneumatic piston which can be pneumatically driven in a pneumatic cylinder to move the stripping piston in the insulating cylinder.
- the problem with this known isolation cylinder is the fact that the piston rod is placed in the area between the stripping piston and the piston rod guide the paint to be applied, so that the adhering to the lateral surface of the piston rod paint can pass through the piston rod guide into the pneumatic cylinder, where the paint then stick the pneumatic cylinder and can block in the worst case.
- Piston rod seal in a so-called dry operation of the piston rod, since then small amounts of paint on the piston rod can dry, resulting in increased abrasiveness and premature failure of the piston rod seal.
- the invention comprises the general technical teaching that the piston rod seal not only has a single seal, but at least two seals, which are arranged offset in the axial direction.
- the additional seal offers increased safety, since the sealing function is not impaired even if a seal fails.
- the arrangement according to the invention of several spatially separate seals makes it possible to monitor faults by monitoring the gap between the two seals for leakage.
- a leakage space is preferably arranged between the two seals in the axial direction, wherein the leakage space is located in the radial direction between the piston rod guide and the lateral surface of the piston rod and absorbs leakage of the paint passing through in the case of a leakage of the paint-side seal.
- a leakage bore extends from the leakage space to dissipate the leakage entering the leakage space.
- the leakage hole can be used to detect leakage.
- the leakage bore lead, for example, to a sensor, which may be, for example, a pressure sensor or a humidity sensor. If the leak sensor detects a leak, the piston rod seal is replaced at the earliest opportunity, which may occur, for example, during normal business interruptions at night or at the weekend, so that the regular painting operation is not affected by a leakage in the piston rod seal.
- the piston rod preferably carries on the opposite side of the stripping a pneumatic piston which is slidably disposed in a pneumatic cylinder and can be pressurized to move the pneumatic piston and thus the piston rod and the stripping piston in the axial direction.
- the piston rod seal according to the invention preferably has a further seal, which is axially offset from the two above-mentioned redundant seals and has the task to seal against the pneumatic cylinder.
- the piston rod seal so three seals, namely two wet paint seals on the side of the Abstreifkolbens or on the side of the insulating cylinder and at least one pneumatic seal on the side of the pneumatic cylinder. Furthermore, it is advantageous in the context of the invention if the seals have a plurality of sealing edges, whereby the life of the seals is increased. In the preferred exemplary embodiment of the invention, therefore, the wet-paint seals each have double sealing edges.
- wet-paint seals are preferably made of a thermoplastic sealing material, such as, for example, polytetrafluoroethylene (PTFE) or polyethylene (PE).
- PTFE polytetrafluoroethylene
- PE polyethylene
- the invention is not limited to the above-mentioned examples in terms of the sealing material, but in principle can be realized with other sealing materials.
- the seals can optionally be supported by a metal spring to achieve a satisfactory sealing effect.
- the piston rod at its sealing surface has a material handling content of more than 60%, 70% or even more than 80%.
- the piston rod has a wear-reducing upper surface on its sealing surface.
- surface coating which may for example consist of a diamond-like carbon layer, such as Dylyn ® or DLC TM (DLC: Diamond ⁇ ike Carbon).
- This surface coating can be carried out, for example, by means of a plasma-assisted chemical vapor deposition method (PACVD: Plasma Assisted Chemical Vapor Deposition) or by a physical vapor deposition method (PVD).
- a plasma-assisted chemical vapor deposition method PVD: Plasma Assisted Chemical Vapor Deposition
- PVD physical vapor deposition method
- the invention is not only directed to a novel piston rod seal as a single component, but also comprises a coating agent supply device and a paint shop, which have such a piston rod seal as a component.
- the invention is not limited to piston rod guides for isolation cylinders in electrostatic coating systems. Rather, the invention is generally suitable for piston rod guides for guiding piston rods in pipeline cylinders.
- the invention also encompasses a novel method of operating such a piston rod seal, in which the insulation atomizer between the stripping piston and the piston rod seal is rinsed with a rinsing agent or a coating agent in order to prevent coating agent residues from depositing on the lateral surface of the piston rod and then through the piston rod guide are dragged through in the axial direction.
- FIG. 1 shows an electrostatic painting installation according to the invention with an insulation cylinder for the electrical insulation of a paint reservoir in relation to a paint dispenser downstream of the paint store,
- Figure 2 is a cross-sectional view of the piston rod guide in the insulating cylinder of Figure 1 and
- FIG. 3 shows a simplified cross-sectional view of a seal in the piston rod guide according to FIG. 2.
- FIG. 1 shows an electrostatic painting installation for serial painting of motor vehicle body parts or other components, the structure and mode of operation of this painting installation being described in detail in patent application DE 10 2005 048 223 A1 cited above, so that the content of this patent application with respect to Structure and the operation of the painting this description is fully attributable.
- the paint shop has a color changer 1, a valve arrangement 2, a paint reservoir 3, a further valve arrangement 4, a paint dispenser 5 and a rotary atomizer 6 as an application device.
- the paint reservoir 3 on the one hand and the paint doser 5 on the other hand can be at different electrical potentials during operation of the paint shop.
- the paint doser 5 when applying the paint, generally has a high-voltage potential in order to achieve optimum adhesion of the applied paint to the electrically grounded motor vehicle body parts.
- the paint reservoir 3 is generally at ground potential during operation of the paint shop, so that the paint store 3 can already be filled with a new paint during painting.
- an insulating cylinder 7 is provided, in which a stripping piston 8 is guided axially displaceable.
- a stripping piston 8 For electrical insulation of the insulating cylinder 7 of the stripping piston 8 is moved to the position shown in the drawing to the right, wherein the stripping piston 8 scrapes paint residues from the inner wall of the insulating cylinder 7 and thereby increases the dielectric strength of the insula onszylinders 7.
- a pneumatic piston 10 is axially displaceable, wherein the pneumatic piston 10 is connected via a piston rod 11 with the stripping piston 8.
- the pneumatic piston 10 can be pressurized by valves on both sides with pressure to move the pneumatic piston 10 and thus also the piston rod 11 and the stripping piston 8 in the axial direction.
- the special feature according to the invention in this case consists in the structural design of a piston rod seal 12, which is shown in Figure 2.
- the piston rod seal 12 has a plurality of components 13, 14, 15, 16 screwed together, which surround the piston rod 11 and receive two wet-paint seals 17, 18 and a pneumatic seal 19.
- the two wet paint seals 17, 18 are in this case arranged on the side facing the insulating cylinder 7 and prevent lacquer from entering the pneumatic cylinder 9 or the piston rod seal 12 from the insulating cylinder 7 in the axial direction through the piston rod seal 12.
- the pneumatic seal 19 is arranged on the pneumatic cylinder 9 facing side of the piston rod seal 12 and pressure-resistant, so that a pneumatic drive pressure in the pneumatic cylinder 9 is maintained.
- piston rod seal 12 has a leakage space 20, which is arranged in the axial direction between the two wet-paint seals 17, 18 and in the radial direction between the lateral surface of the piston rod 11 and the surrounding component 14.
- a leakage bore 21 originates from the leakage chamber 20, which is led to the outside and allows the connection of a leakage sensor, which is not shown here for the sake of simplicity. If the wet-paint gasket 17 leaks, wet paint then enters the leakage chamber 20, which can be detected by the leakage sensor via the leakage bore 21. In this state, the sealing function is still maintained by the second wet paint seal 18, so that the drove the paint shop is not disturbed. At the next regular business interruption then the piston rod seal 12 can be replaced.
- FIG. 3 shows a possible embodiment of the wet-paint seal 17 with two sealing edges 22, 23, whereby the service life of the wet-paint seal 17 is advantageously increased.
