Abstract:
A screw compressor system for a utility vehicle includes at least one screw compressor and at least one control and/or regulation unit for controlling and regulating the screw compressor. The control and/or regulation unit is designed such that the screw compressor is prevented, for a determined period of time, from re-starting after being stopped.
Abstract:
A system includes a compressor, a control unite and a clutch assigned to the compressor. The control unit is suitable for opening and closing the clutch in order to economize energy. The control unit is suitable for carrying out a monitoring routine during which the clutch is opened or closed in order to prevent the clutch, the compressor and the components arranged downstream of the compressor from being damaged. A method for controlling the system, including the compressor, the control unit and the clutch associated with the compressor, is also provided.
Abstract:
A supercharged compressor and method of operating the compressor supplies a commercial vehicle with compressed air. The compressor includes a piston chamber, a dead space or clearance volume and a valve unit for switching the clearance volume. The valve element is configured such that the air volume supplied by the supercharged compressor can be reduced to a value that is different from zero by activating the clearance volume.
Abstract:
A screw compressor for a utility vehicle has at least one housing with at least one housing cover and with at least one rotor housing, at least one baffle plate and at least one seal. In the assembled state, an oil sump is present in the housing, wherein, with regard to the assembled state, the seal is arranged between housing cover and rotor housing and projects out of the oil sump. The seal at least partially separates the interior of the housing cover from the interior of the rotor housing. With regard to the assembled state, in the case of a substantially horizontal orientation of the screw-type compressor and in the case of a substantially horizontal orientation of the oil sump, the baffle plate is oriented substantially parallel to the upper level of the oil sump.
Abstract:
A method produces a housing of a rotary screw compressor, the housing having at least one housing body and at least one housing cover. The method includes the following steps: bearing seats for at least one screw rotor of the rotary screw compressor are provided in the housing body and in the housing cover; at least one screw borehole for the at least one screw rotor of the rotary screw compressor is provided in the housing body; the housing body and the housing cover are temporarily assembled using at least one alignment tool for ensuring the alignment of the screw rotor central axis with the central axes of the bearing seats and the screw borehole; and at least one bolt insertion opening is provided in both the housing body and the housing cover by at least one common production process.
Abstract:
A screw compressor for a utility vehicle has at least one female screw, at least one male screw that meshes with the female screw, and at least one screw compressor drive which drives the female screw.
Abstract:
A compressor system includes a compressor for supplying compressed air to a commercial vehicle that has an engine with a turbocharger. Air that is pre-compressed by the turbocharger can be sucked in by the compressor via a first air supply pipe. Ambient air that is not pre-compressed can be sucked in by the compressor via a second air supply pipe. A method operates the compressor system including the compressor for supplying the compressed air to the commercial vehicle that has the engine with the turbocharger accordingly.
Abstract:
A compact dry-running piston compressor includes at least one cylinder for the compression of air by a corresponding piston, which may be driven by an electric motor with a crank drive made up of a crankshaft and connecting rod. The crank drive is rotatably mounted in an oil-bath-free compressor housing on pre-lubricated roller bearings and generates an internal cooling air flow inside the housing due to its movement cycle. The compressor housing includes two housing sections separated by a partition wall, in order to accommodate the crank drive within the first housing half and the electric motor in the second housing half. A roller bearing common to the crank drive and the electric motor is arranged in the partition wall lying in the cooling air flow passing through the first housing half.
