Abstract

The invention relates to a marine main unit integrated rack, particularly a marine main unit modular integrated rack with a steam emission function. To overcome a problem that exist marine main unit frame structures can not meet the requirements of compactness, integration, modularization and vibration damping installation, the marine main unit modular integrated rack having a steam emission function is provided and includes a high pressure steam turbine frame, a low-pressure steam turbine frame and a reducer frame. The high-pressure steam turbine frame is connected with the low-pressure steamturbine frame. The reducer frame is respectively connected with the high-pressure steam turbine frame and the low-pressure steam turbine frame, each frame is connected by a connector, the central part of the low-pressure steam turbine frame is provided with a through hole, the upper part of the through hole is connected with the steam turbine exhaust end, and the lower part is used for connectingwith the condenser. Each frame comprises two upper and lower panels; a reinforcing rib is arranged between the panels; and a vibration isolator is also arranged at the bottom of the frame. The modular integrated rack is used for supporting and placing the marine main unit.

Description

technical field [0001] The invention relates to a marine main unit frame, in particular to a marine main unit modularized integrated frame with steam discharge function. Background technique [0002] Marine main units include low-pressure steam turbines, high-pressure steam turbines, reducers and condensers, which are one of the main mechanical noise sources of ships. At the same time, their relatively large dimensions also bring certain difficulties to the layout of various equipment in the engine room. Due to the limitations of the inherent structure, it is difficult to achieve a breakthrough in the integration of the traditional unit support form. Contents of the invention [0003] The object of the present invention is to solve the problem that the frame structure of the marine main unit cannot meet the requirements of compactness, integration, modularization and vibration damping installation, and provide a modularized integrated frame of the marine main unit with the...
