Problems solved by technology

This is very inefficient and limits the maximum heat dissipation across the bearing
[0004] However, it has been shown in practice that under certain operating conditions, such as high outside air temperatures, the mentioned cooling techniques are insufficient and expensive, leading to increased wear and even bearing failure or high bearing housing costs

Embodiment Construction

[0032] In the following description, reference is made by way of example to an important application, namely the flow machine is designed as a centrifugal pump.

[0033] figure 1 A cross-sectional view of an embodiment of a flow machine according to the invention is shown, designated as a whole by the reference numeral 100 . An example of a flow machine 100 is a centrifugal pump 100 for conveying fluids such as water or crude oil or multiphase liquids. Obviously, the present invention is neither limited to figure 1 The centrifugal pump 100 shown in , is also not limited to such a centrifugal pump, but rather refers to the flow machine 100 in general. For example, flow machine 100 could also be another type of pump, compressor, fan, expander, or turbine.

[0034] The centrifugal pump 100 comprises a housing 101 which may consist of a plurality of housing parts connected to each other to form the housing 101 . The housing 101 of the centrifugal pump 100 comprises an inlet 10...

Abstract

The invention relates to a bearing housing for a flow machine and the flow machine with the bearing housing. The invention relates to the bearing housing for the flow machine (100), and the bearing housing (115) comprises a bearing chamber (200) for receiving a bearing (116) and a lubricant chamber (202) arranged on the bearing chamber (200) for receiving a lubricant, and the bearing chamber (200) is in fluid communication with the lubricant chamber (202) via an opening (222) such that the lubricant can flow between the bearing chamber (200) and the lubricant chamber (202). The bearing housing (200) comprises a wall portion (215) with fins (10) for dissipating the heat of the lubricant to the environment, and is characterized in that the fins (10) comprise a conduit (11) for the lubricant through which the lubricant chamber (202) and the bearing chamber (200) are in fluid communication such that the lubricant can be introduced from the lubricant chamber (202) into the bearing chamber (200) through the conduit (11) for dissipating heat to the environment.

Description

technical field [0001] The invention relates to a bearing housing for a flow machine according to the preamble of independent claim 1 . The invention also relates to a mobile machine with a bearing housing according to independent claim 11 . Background technique [0002] A flow machine for conveying fluids, such as a centrifugal pump, compressor, fan, expander, or turbine, typically includes a stationary machine housing enclosing a rotor, such as an impeller, arranged on a shaft that rotates about the axis of the flow machine . The flow machine also has at least one bearing unit with radial and / or axial (thrust) bearings to support the shaft and rotor. Typically the bearing unit has a separate bearing housing which is firmly connected to the housing of the flow machine. In this case, the bearing housing comprises a bearing axis, a bearing chamber for accommodating the bearing and a lubricant chamber for accommodating lubricant. The lubricant chamber and the bearing chamb...
