- A screw compressor system of the initially mentioned type is known, for example, from German Patent DE 100 33 154 C2.
- The purpose of the invention is to develop a screw compressor system of the aforementioned type such that it will achieve a construction that is as compact as possible with flexibility that is as great as possible with respect to the manner of design of the screw compressor system. Also, the construction principle in accordance with the invention can be used in screw compressor systems with a different construction.
- In accordance with the invention, a screw compressor system which comprises the initially named functional parts is made available which is characterized in that it is designed as a modular construction to be compact and flexible such that the screw compressor block, the oil separation tank, the oil supply duct for the oil temperature controller and the air intake duct are combined in a base housing with a lid and/or that the fine separator, the oil return, the minimum pressure-maintaining valve with the clean air outlet, the oil temperature controller, the oil filter and the connections for the cooler are combined in a multifunction block.
- To achieve a design of the screw compressor system which is as compact as possible but which can also be flexibly varied, in accordance with the invention, to achieve a modular construction, a base housing can be used into which corresponding functional parts of the screw compressor system are integrated, and furthermore, a multifunction block which can be variably used in a flexible manner and into which other functionally important parts of the screw compressor system are integrated can be used. The screw compressor system in accordance with the invention thus, in the manner of a modular system, comprises two base components, specifically a base housing with a lid and/or a multifunction block. In this way, the screw compressor system in accordance with the invention can be adapted to the respectively desired requirements and demands. In this case, there are common base components in the modular system, as a result of which a construction which is more favorable to production with reduced production costs can be implemented.
- Other preferred configurations and details of the screw compressor system in accordance with the invention are explained in detail below using a nonlimiting exemplary embodiment with reference to the accompanying drawings.
-
FIG. 1 is a perspective exploded view of a screw compressor system in accordance with the invention, -
FIG. 2 is a perspective view of the screw compressor system shown inFIG. 1 in the assembled state, -
FIG. 3 is a perspective partially exploded view of the above embodiment of a screw compressor system viewed in a direction looking at the operator side and the drive side of the system, -
FIG. 4 is a perspective view of the screw compressor system as shown inFIG. 3 in the mounted assembly position. - The same or similar parts are labeled with the same reference numbers in the figures. The illustrated embodiment is simply one exemplary embodiment which is not of a character intend to limit the invention.
-
FIGS. 1 and 2 show an overall screw compressor system 1 in accordance with the invention with only the functionally important parts of this screw compressor system being shown. However, the construction principle of the invention in a modular construction can be recognized from the figures of the drawings. - The illustrated screw compressor system 1 comprises a
base housing 2 as the base module whose interior can be closed with alid 3. In thisbase housing 2, as the base module in the combined arrangement, a screw compressor block, an oil separation tank, an oil supply duct for the oil temperature controller and the air intake duct are integrated. Anintake valve 5 with anintake filter 6 mounted on it is shown schematically inFIG. 1 in an exploded view. Theintake valve 5 with theintake filter 6 is mounted on thebase housing part 2 as shown inFIG. 2 . Furthermore,FIG. 1 shows amultifunction block 10. In thismultifunction block 10, a fine separator, an oil return, a minimum pressure-maintaining valve with a clear air outlet, an oil temperature controller, an oil filter and optional connections for a cooler are combined. Thismultifunction block 10 can be adapted to the demands and requirements to be satisfied with respect to the filter apparatus and the like. A schematically indicatedcontrol unit 11 is dynamically connected to themultifunction block 10. - The assembly representation in
FIG. 1 shows that this screw compressor system 1 is designed to be compact and can be flexibly adapted with respect to requirements. - In addition,
FIGS. 3 and 4 show details with respect to adrive side 15 and anoperator side 16. - Thus, the
multifunction block 10 is located on theoperator side 16 of the screw compressor system 1 and is therefore easily accessible for necessary maintenance work without other functional parts of the screw compressor system 1 having to be dismounted. Thedrive side 15 lies somewhat at a right angle to theoperator side 16 on which themultifunction block 10 is located and attached. Thus, there is unhindered access to thedrive side 15 of the screw compressor system 1. - Of course, the invention is not limited to the above described design details so that numerous changes and modifications are possible without departing from the essence of the invention which can be seen in that the functionally necessary components of a screw compressor system 1 as a module component in the manner of a modular system, on the one hand, are assigned to a
base housing 2 as the base module, and on the other hand, to amultifunction block 10 as a further functional component in order to enable a compact and flexible design of the screw compressor system in accordance with the invention.
