Problems solved by technology

However, the radial play cannot be reduced arbitrarily, because the thermal loading of the housing and the remaining machine parts, especially in the case of unstable operation, is not the same for all machine components, and thus occurs—also due to Different materials cause - thermal relative expansion that can cause gap reduction

Embodiment Construction

[0022] figure 1 Shown is a turbomachine TM, ie a turbocompressor TCO with a housing CAS or a turbocompressor housing according to the invention. The casing CAS extends along the longitudinal axis AX and has a horizontal joint TF held together by means of joint screws TFS. The housing CAS can be subdivided into a housing part SH and a cover COV. The cover SH is provided with a horizontal joint TF. The cover COV is undivided and has a substantially planar extension perpendicular to the longitudinal axis AX, which has a substantially circular outer contour. In the region around the longitudinal axis of the housing part SH, the cover has an opening OP substantially concentric to the circular outer contour, through which opening OP the rotor R extending along the longitudinal axis AX emerges from the housing CAS. The cover COV carries the shaft seal SSL and the radial bearing BE. The shaft seal SSL includes a labyrinth seal LS, a dry gas seal DGS, and a carbon ring seal KRS in ...

Abstract

The invention relates to a housing (CAS) having a longitudinal axis (AX) of a turbomachine (TM), the axis extending along a rotor (R), in particular to a turbocompressor housing, comprising at least one jacket part (SH) extending along the longitudinal axis (AX) and at least one end-face cover (COV), wherein said cover (COV) is surrounded by the jacket part (SH) at least with a part of the axial extension of the cover. In order to reduce the need for radial clearance, without compromising the availability or safety of the operation of the machine, the cover (COV) has radial clearance (RCL) with respect to the jacket part (SH) and at least two separate guide elements (GE) of the cover (COV) are provided on the jacket part (SH) in two different circumferential positions with respect to the longitudinal axis (AX), wherein the respective guide elements (GE) are designed such that they block a respective movement of the cover (COV) in the circumferential direction at least unidirectionally.

Description

technical field [0001] The invention relates to a housing of a turbomachine, in particular a turbocompressor housing, having a longitudinal axis extending along the rotor, said housing comprising at least one outer casing part extending along the longitudinal axis and at least one end-side cover, At least a portion of the axial extension of the cover is surrounded by the outer casing. Background technique [0002] Such a housing can be used in connection with almost any turbine, irrespective of whether it is an axial or a radial turbine. Furthermore, this design is conceivable for a turbine with a horizontally divided housing or a turbine of pot design or a turbine with a vertical joint. In compression turbines and expansion turbines, the temperature and pressure of the process fluid are decisive for, inter alia, the design and dimensions of the housing. An obvious weak point of the housing is the point at which access to the interior of the housing is achieved, ie, for ex...
