Description

A double-station tooling for nozzle ring

Technical Field

The utility model relates to the technical field of nozzle rings, in particular to a double-station tooling for a nozzle ring.

Background Art

The marine turbocharger also has a nozzle ring on the outside of the turbine impeller. The exhaust gas enters the turbine impeller through the nozzle ring and transmits power to the turbine impeller. The function of the nozzle ring is to control the amount of exhaust gas entering the turbine impeller to control the speed of the turbocharger. At present, when the nozzle ring of a marine turbocharger is damaged, it is generally repaired, which requires operations such as grinding, shaping and spraying.
