How was the power plant of the destroyer Gaolang built?

The power plant of Japanese Gao Qiao class destroyer: Gao Qiao class adopts propulsion mode. Its four main engines are divided into two types, and the engine room is arranged on the left and right sides. The front is the first engine room, which is the port propulsion shafting, and the back is the second engine room, which is the starboard propulsion shafting, so the left transmission shaft is longer than the right transmission shaft. The computer room is equipped with two main engines and corresponding deceleration system. The configuration mode is that the first computer room is equipped with 1 and 2 hosts, and the second computer room is equipped with 3 and 4 hosts.

Among them, 1 and No.4 main engines are LM2500 gas turbines of American General Dynamics Company, with single output power of 12. 1 MW, and No.2 and No.3 main engines are "Spey" gas turbines of British Rolls-Royce Company, with single output power of 9.9 MW and total speed of the whole ship reaching 44.1.

Because the two main engines can run at different speeds because of the speed, and the propeller with large diameter and oblique alternating pitch is used to slow down, the noise in the water is greatly reduced, which is beneficial to anti-submarine warfare. The steering gear is the same as the original destroyer, and there is no big change.

The ship is equipped with three generators, the power is 1.5 MW, and the electricity consumption can be met by two generators at ordinary times. The third generator is a backup system. 1 No.2 generators are installed in the corresponding first and second engine rooms, and the third main generator is installed in the generator room independently set at the rear.

A 600 kW auxiliary generator is installed in the auxiliary engine room of the engine room, which is mainly used to ensure the power supply when the ship berths. In order to improve the survivability of warships, the switchboard room and IC room are overlapped, and a set of independent ones is set in front and back of the hull, so as to ensure that warships can still have certain combat capability after being hit in wartime to the greatest extent.

Main control room is located on the second deck in the center of the hull. Like destroyers in the past, it is also used as an emergency command room. In addition to the main console, the control room is also equipped with auxiliary console, power console and emergency monitoring system, where various auxiliary machines can be started and controlled to monitor the operation of the engine room.

The bottom cabin is an auxiliary engine room, which is equipped with a series of auxiliary equipment such as auxiliary boiler, seawater desalination device, various pumps and anti-rolling wings. Unlike American ships, the bathroom and air conditioner on board are powered by steam provided by auxiliary boilers. The bridge is equipped with a bridge control system, which can accurately reflect the situation of warships and engine rooms.
