Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Um die zu grofse Erhitzung der Verdichter, ihrer Kolben und Stopfbüchsen bei der Verdichtung zu vermeiden, wird vielfach das arbeitende Mittel, z.B. Ammoniak, nicht vollständig verdampft angesaugt, sondern zum Theil noch flüssig. Dieser flüssige Theil verdampft dann noch während des Ansaugens infolge des dort entstehenden verdünnten Raumes und kühlt die Verdichterwandungen, den Kolben und die Kolbenstange. - Diese Art Kühlung macht aber gegenüber dem Fall, dafs nur trockener Dampf angesaugt wird, einen um so viel gröfseren Verdichterraum nothwendig, als der bei dieser Verdampfung entstehende Dampf Raum einnimmt; dementsprechend erfordert der Verdichter auch mehr Arbeit.About the excessive heating of the compressors, their pistons and stuffing boxes during compression to avoid, the working agent, e.g. ammonia, is often incomplete evaporates, sucked in, but partly still liquid. This liquid part evaporates then still during suction as a result of the thinned space created there and cools the compressor walls, the piston and the piston rod. - This kind of cooling, however, compared to the case, makes that only dry steam is sucked in, so a much larger compressor space is necessary, than the vapor produced by this evaporation takes up space; accordingly, the compressor also requires more Job.

Diesem Uebelstand soll nun dadurch abgeholfen werden, dafs der durch Rohr A vom Verdampfer kommende kalte Dampf, ehe er in den Verdichter gelangt, erst den von einem Mantel umgebenen Verdichter, sowie Deckel und Stopfbüchse umspült und kühlt. Zu diesem Zweck kann entweder der ganze Arbeitsdampf oder nur ein Theil desselben benutzt werden. Dabei wird der etwa noch feuchte Dampf getrocknet und gelangt, ohne mit Flüssigkeit behaftet zu sein, in den Verdichter. This problem is now to be remedied by the fact that the cold steam coming from the evaporator through pipe A , before it reaches the compressor, first rinses and cools the compressor, which is surrounded by a jacket, as well as the cover and stuffing box. Either all or part of the working steam can be used for this purpose. The steam, which is still damp, is dried and reaches the compressor without being contaminated with liquid.

Der Verdichter braucht dann nur die für den Arbeitsdampf nöthige Grofse zu haben, wodurch an Anlage- und Betriebskosten gespart wird.The compressor then only needs to have the size necessary for the working steam, which saves investment and operating costs.
