Definitions
- the invention relates to a compressed air maintenance device which is composed of individual, easily exchangeable modules such as pressure regulators, oil atomizers, condensate separators, the individual modules possibly having transmitters for the current operating state and / or predetermined limit values.
- Such a compressed air maintenance device is known from DE 40 32 515 AI.
- Monitoring the operating states of the individual modules is difficult due to the different arrangement of the detectors. Malfunctions or necessary maintenance work are so difficult to identify and there is a risk that necessary maintenance work will not be carried out.
- Through the different forms of the individual modules the overall impression of such a maintenance device is not pleasing.
- the present invention is based on the object of developing a compressed air maintenance device of the type mentioned at the outset in such a way that required maintenance work or malfunctions can be easily identified.
- the invention provides that in addition to the individual modules, a display and monitoring module is provided, that this module has optical and / or acoustic detectors for the operating or fault states determined by the individual modules, and that these detectors can be easily coupled are connected to the assigned sensors of the modules. It is particularly important to arrange a detector for the operating pressure and detectors for the fill level limit values of the corresponding modules.
- An optically closed appearance with a particularly clear arrangement of the detectors can be achieved in that the individual modules have hollow profiles with undercut longitudinal grooves are easily connected to one another via the adjacent modules.
- the shape of the modules arranged next to one another can be optimally adapted to one another, thus ensuring an optimal industrial design.
- U-shaped brackets are provided, the legs of which are received in adjacent grooves of the modules to be connected. This means that individual modules can be exchanged in a few simple steps, even without tools.
- Each hollow profile expediently has at least four longitudinal grooves, in order to hold two adjacent modules together with a clamp, without further measures being necessary for the tight connection of possibly continuous supply channels.
- the display and monitoring module can have an exchangeable insert part in which at least one circuit board for the electronics of the detectors is held, the board carrying plug connections for transmission lines with the sensors of the modules.
- Appropriate slide-in parts can then be selected according to the requirements and used in the display and monitoring module. Thanks to the simple replacement of parts, maintenance and, in particular, repairs can be carried out in a time-saving manner with minimal effort, even during operation.
- the insertion part is expediently designed to be axially insertable into the hollow profile. Furthermore, the insertion part can be designed to be open at the bottom for the supply of transmission lines which can be placed on the plug connections from the sensors of the modules.
- the insert part can have a faceplate lying in front of the hollow profile, in which the visual displays of the detectors are arranged in a clearly visible manner.
- the insert part can have an air coupling, via which pressure sensors of the display and monitoring module are connected to the air duct going through all modules, the air coupling being closed automatically when the insert part is removed.
- the air coupling can be fixed with the insert part have connected tappet trunk by which a valve body of the air clutch is held in its "installation".
- each module has a head piece which closes off the hollow profile at the top and through which an air duct is guided. Furthermore, each module that has a hollow profile has a foot piece that closes off the hollow profile at the bottom, wherein transmission lines connecting transmitters and detectors are guided in the foot piece, possibly behind an additional cover.
- the essential functional elements of the modules are carried by the head and foot pieces, so that they are pre-assembled and can simply be attached to the hollow profiles during final assembly. The head piece and the foot piece each close the associated hollow profile so that no additional sealing measures are required for the individual components.
- a slot-shaped opening which is tightly closed by a viewing window, can be provided in the hollow profile, so as to make the level of the oil supply of an oil nebulizer or a condensate separator easily recognizable.
- FIG. 1 shows a front view of a compressed air maintenance device
- FIG. 2 shows a section through the maintenance device shown in FIG. 1,
- FIG. 3 shows a section along the line III-III in Figure 2 by a display and monitoring module
- Figure 4 shows a further section along the line IV-IV in Figure 2 with the omission of the module internals.
- Compressed air maintenance device three modules 1 are provided, namely a condensate separator 1 ', a display and monitoring module 1 "and an oil atomizer 1"'.
- the individual modules 1 each have an extruded hollow profile 2 ', 2 ", 2"', preferably made of aluminum, each of which has a head piece 3 ', 3 "or 3 n at the top and a foot piece 4', 4 at the bottom ", 4"'is closed.
- An air duct 5 is guided through the head pieces 3 ', 3 ", 3 1 ".
- condensate separator 1 ' condensate is separated from the air passed through the air duct 5 in a known manner and accumulates below in the hollow profile 1 '.
- the accumulated condensate can be excreted via a protective filter 6 through a drain valve 7.
- two transmitters 8 are arranged in the form of a level probe, the upper free end of which gives a signal to a detector 10 via a transmission line 9 when the condensate level rises.
- a viewing window 12 can be provided in an opening 11 of the hollow profile 2 'in order to make the respective condensate level easily recognizable.
- the structure of the condensate separator is known, with the exception that the essential parts are held in the head piece 3 'or foot piece 4', so a more detailed description of the function does not appear to be necessary.
- There two sensors 8 are arranged in the foot piece 4 '', by means of which the fill level is determined in order to make the oil level limits recognizable in a known simple manner via a transmission line 9 'on the detector 10' of the display and monitoring module 1 ".
- the display and monitoring module 1 "has an insert part 13 which can be inserted into the hollow profile 1" from below and in which the display electronics in particular have one or more circuit boards 14 with the required electronic components are housed, as indicated in Figure 3. At least one of the boards 14 has plug connections 15 for plugs 16 of the transmission lines 9, 9 '.
- One of the boards 14 can be designed as a viewing board 14 'for receiving the optical display elements, as can be seen from FIGS. 1 and 3.
- a digital pressure display 17 for the current operating pressure can also be provided here.
- a pressure sensor 18 for monitoring the operating pressure in the air duct 5 can expediently also be provided in the insertion part 3.
- an air coupling 19 is provided in the head piece 3 ′′, which has a valve body 20 which is kept open in its installed state via a tappet 21 of the insert part 13 and thus the channel 5 with the To connect pressure sensor 18.
- the individual modules 1, as can be seen in particular from FIG. 4, are connected to one another by clips 22.
- the hollow profiles 2 have undercut longitudinal grooves 23.
- Each hollow profile 2 ', 2 ", 2"' is provided with at least four such longitudinal grooves 23. These have an L cross section, while the legs of the U-shaped brackets 22 have an adapted U cross section.
- the hollow profiles 2 ', 2 "' of the condensate separator 1 'and the oil atomizer 1"' are of identical design, so that rational production is possible.
- These hollow profiles 2 ', 2 M have additional longitudinal grooves 23'. They can be used, for example, for an additional wall mounting of the compressed air maintenance device, but they can also be used to hold signs for maintenance instructions and the like.
- the entire monitoring system can be connected to the company's IT system via a single connection, so that monitoring and control can be carried out from practically any location.
