ABB TPS52-F32 Two Hole Turbine Casing Design 51000 Casing In Turbine

Description:

As to ABB TPS52-F32 Two Hole Turbine Casing Design 51000 Casing In Turbine, the shell body com–

prises a first end, a second end and a central region, wherein the shell body includes an inner cavity

through which the inner cavity gradually shrinks from a first larger section at and / or in the regions of

the first end and the second end toward the central region to a second smaller section. The turbine casing

may include a fluid flow limiting device, which is arranged to limit the fluid velocity, direction or position in the

turbine casing.

About ABB TPS52-F32 Two Hole Turbine Casing Design 51000

The turbine hood is an essential component of TPL-A and TPL-C turbochargers. It has two main functions:

First, to protect the bearing casing from the high temperatures caused by the exhaust gases and, second, to

guide the exhaust gas with minimum losses through the gas outlet casing.

To allow for thermal expansion of the sheet metal, the turbine hood is clamped between the bearing casing

and gas outlet casing (see figure below).

The turbine hood is designed to ensure it remains properly clamped over the complete lifetime of the turbo-

charger. However, vibration, an increase in the number of load changes or turbine-side cleaning cycles can

cause wear at the clamping shoulders of the bearing casing and the gas outlet casing. Increased wear causes

a reduction in the clamping force, which could result in uncontrolled movement of the turbine hood.
