摘要:
In a method of manufacturing a plurality of steam turbines for use in various applications which differ in the respective thermodynamic parameters such as, for example, cooling-water temperature, ambient temperature, given boiler data, process-steam requirement, etc., the steam turbines in each case having at least one high-pressure part with first blading and a control-wheel stage for part-load operation, a simplification and cost saving is achieved owing to the fact that standard blading, which is identical for all the steam turbines, is used as first blading, and in that the adaption of the individual steam turbine to the thermodynamic parameters of the respective application is carried out by appropriate design or variation of the control-wheel stage.

A filtering plant for removing dusts from gases, with a plurality of filter units, which are parallel connected to a line for crude gas and the outlets thereof are parallel connected to a line for purified gas, wherein an extraction blowing engine is connected to the line for purified gas, further with an apparatus for cleaning the filter units, which has a lower collecting space for the filter cake with a discharge opening with flap on the lower end of the collecting space, characterized in that the dust discharge openings of all the filter units except one are connected to a common collecting main and the collecting main is connected to the crude gas region of the one filter unit.
摘要:
A cooling system for a rotary tablet press with which a rotor is driven by an electrical drive motor and the rotor and drive motor are arranged in a closed housing, and a control cabinet for the drive motor and further units in the housing, wherein arranged within the housing is a cooling machine whose evaporator is part of a first heat exchanger, whose other part is arranged in a coolant circuit for the drive motor, a fan is arranged in a channel in the housing closed relative to the housing interior, where the fan draws cool air in via an air inlet of the housing and gives it off via an air outlet of the housing, wherein the cool air is engaged in heat exchange with a condenser of the cooling machine.
摘要:
An apparatus for the elimination of dusts from gases, with a filter arrangement, which is flown through by a loaded volume flow, and a cyclone which is arranged upstream to the filter arrangement, wherein a collector funnel below the filter arrangement forms the cover of the cyclone, wherein a branch stub forming the dust outlet opening of the collector funnel forms the dip pipe of the cyclone and an outlet opening of the cyclone is connected to a dust collector tank arranged under it.
摘要:
Rotary press with a rotor, rotatingly drivable around a vertical axis of rotation, which has a die plate with die bores and upper and lower punches guided in guidings, radial cams for the upper and lower punches, at least one compression station with upper and lower pressing roller, at least one filling equipment and at least one stripping device for pressed articles which are ejected from the die bores, characterized in that the rotor has an annular plane situated radially outside of the graduated circle for the die bores, which is concentric to the axis of rotation and is lowered with respect to the upper side of the die plate about a predetermined degree, first deflection portion direct the ejected pressed articles to the annular plane and second deflection portion direct the pressed articles from the annular plane towards the outside.
摘要:
In a brush seal for sealing off the gap between a rotating and a stationary component, a plurality of radially inwardly running, elastically flexible brushes are held at one end in a basic body seated in a first of the components. They bear sealingly at the other end on the annular other component. The brushes bear, over their predominant longitudinal extent, on a guide plate. Both the basic body and the guide plate are seated in a groove of one of the components. The basic body and the guide plate are held in their mutual position by means of a wire mortised into the groove.
