Definitions
- the invention relates to a screw compressor, in particular for use in a vehicle, wherein the screw compressor has an oil sump with a
- Such a screw compressor is known from DE 10 2004 060 417 AI.
- This screw compressor is designed for mobile use in a vehicle, the subject matter of this document is concerned with making the speed of the motor unit alone associated with the screw compressor in accordance with a control unit adjustable so that the
- Screw compressor regardless of the drive unit of the vehicle generates a predetermined flow rate of compressed air. Constructive is the
- Screw compressor designed so that a first housing part of the multi-part
- Housing has an oil sump with a ⁇ lschwappdämpfungs adopted, wherein the ⁇ lschwappdämpfungs worn is not defined.
- This oil swirl damping device is installed in a manual transmission housing for a vehicle and formed in the form of ribs, which are arranged in the bottom region of the transmission housing.
- the invention is based on the object, a screw compressor
- Oil slosh are insufficient and can not prevent the oil can run up to the housing walls. This effect occurs in particular in screw compressors used in vehicles such as road vehicles and / or rail vehicles, in which, caused by strong accelerations and vibrations, oil sloshing occurs. Such oil sloshing does not assure reliable oil separation in a final separator stage as the final separator stage of the oil separator apparatus is overloaded by the direct access of oil.
- the barrier device is designed in one or more stages. Especially with multi-stage design of the barrier device the oil sloshing is reliably prevented.
- the barrier device is at least one vertically inserted into the oil sump above an oil level installation.
- This installation is in turn in a preferred further embodiment, a perforated plate.
- a perforated plate is available in different variants or easy to manufacture. On the one hand, such a perforated plate ensures that out of the
- Housing wall runs up and gets back into the separator. This is achieved particularly effectively when two perforated plates offset from one another and one above the other are used in the housing forming the oil sump. This ensures that oil or oil drops that have passed through an opening in the lower perforated plate and have peeled off, are caught by the second perforated plate, adhere to this and are returned by gravity back into the oil sump.
- the size of the holes of the perforated plate is to be dimensioned so that the total oil to be introduced into the oil sump flows through a plurality of holes, ie, the volume flow to be introduced into the oil sump is divided into a plurality of small volume flows. Correspondingly small, the holes can be formed and oil sloshing can be prevented. It can also be provided to make the diameter of the holes differently, for example, the diameter in the region of the housing walls may be smaller than in the middle of the oil sump. Such a design supports the
- the incorporation is as an oil permeable
- Such a structure is, for example, a porous body, which may be made of ceramic foam, for example. However, such a structure may for example consist of several arranged in different directions sheet metal elements.
- FIG. 1 shows a section through a screw compressor shown schematically
- FIG. 2 shows a perspective view of FIG. 1.
- a screw compressor has a pressure vessel in which oil collects to form an oil sump 1.
- Such a screw compressor is provided, for example, in road vehicles and / or rail vehicles for the production of compressed air, which is required inter alia for the supply of compressed air brake systems. Oil will be resistant to such
- the oil level in the pressure vessel can vary greatly.
- the oil level reaches a relatively high value at idle mode or standstill above a minimum level, while in a subsequent switching to the load operation of the oil level by the then switched promotion by the screw compressor or - which should be avoided - fall below a minimum level.
- Such fluctuations in particular towards falling below a minimum level, are exacerbated by leakage or natural consumption.
- the use of the machine or of the vehicle for example when operating with an inclined position, also affects the oil level of the installed screw compressor. On top of that, caused by
- the oil supplied from the first separation stage collects in the bottom region of an oil sump 2 and is returned to the lubricating and cooling circuit of the screw compressor through a suction opening 3.
- a first perforated plate 5a is arranged and with a small distance above the first perforated plate 5a, a second perforated plate 5b is attached.
- the perforated plates 5a, 5b are - as the perspective view of Figure 2 can be seen - arranged offset from one another, that - caused by strong acceleration and / or vibration - from the oil sump 2 through an opening or a hole of the first perforated plate. 5 a passing and peeling oil surge or oil drops on the wall of the second perforated plate 5 b occurs.
- the perforated plates 5a, 5b may be made of a metallic or non-metallic
