Arrangement of components in a fluid energy machine and assembly method

Abstract

An assembly method and an arrangement of components in a fluid energy machine, in particular a turbocompressor, with a longitudinal axis. The arrangement includes: an inner bundle to be arranged in an outer casing of the fluid energy machine, a low-pressure unit of the fluid energy machine, at least one cover of the fluid energy machine for the axial end-side closure of the outer casing on at least one end side, wherein these components are arranged axially adjacent to one another in the sequence cover, low-pressure unit, inner bundle and the cover is releasably attached to the low-pressure unit and the inner bundle is releasably attached to the low-pressure unit such that there results a transportable unit.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is the US National Stage of International Application No. PCT / EP2015 / 058412 filed Apr. 17, 2015, and claims the benefit thereof. The International Application claims the benefit of German Application No. DE 102014207461.4 filed Apr. 17, 2014. All of the applications are incorporated by reference herein in their entirety.FIELD OF INVENTION[0002]The invention relates to an arrangement of components of a fluid energy machine, in particular of a turbocompressor, with a longitudinal axis, comprising an inner bundle for arrangement in an outer housing, a low-pressure insert, and at least one cover for the axial face-side closure of the outer housing at at least one face side.BACKGROUND OF INVENTION[0003]Such fluid energy machines or arrangements of the type mentioned in the introduction are already known from, for example, EP 2 024 646 B1 or EP 1 952 030 B1. The latter document also describes an assembly method for a turbocompr...

AI Technical Summary

Benefits of technology

The patent aims to improve the standardization of different sizes of fluid energy machines or radial turbocompressors. It does this by securing the mounting sleeves in place. This helps to ensure that the cover, which is connected to the first mounting sleeve, is also securely in place. This improves the stability and efficiency of the system.

Problems solved by technology

Here, damage can be caused to adjacent components, for example to the corresponding cover seals or to the shaft seals, or damage can be caused in the event of an offset of the rotor relative to the static components—that is to say the stator—of said transportable unit.

Furthermore, said assembly must subsequently be rotated into the operating position again, which likewise harbors the risk of damage and necessitates a reorientation of the housing.

Such an apparatus has only a limited load capacity and is therefore suitable only for machines up to a particular structural size.
