Two oil coolers each. Two main fire pumps (100m3/h); two bilge pumps (120m3/h) and one general bilge pump (300m3/h); two sets of WP260 air compressor units, each with a pump displacement of 84m3/ h; three main air bottles, one auxiliary air bottle, one control air bottle, one miscellaneous air bottle, one air whistle bottle and one starting air bottle for the power generation diesel engine. There are two fuel oil separators, two lubricant oil separators, and one diesel oil separator.
?Two sets of variable pitch propeller control combination cabinets are installed at the rear of the engine room.
2). In order to reduce the rolling of the ship and ensure the safety of the ship and the comfort of the crew and passengers, the ship is equipped with a set of anti-rolling devices in the left and right fin stabilizer compartments. In addition, in order to ensure the safety of the ship when loading and unloading vehicles, the ship is equipped with a heel balance device. When the ship heels exceeds 2°, the heel balance pump starts to work and automatically restores the heel angle to within 2°. At the same time, in order to improve the maneuverability of the ship, two sets of side thrust devices are equipped in the bow thrust cabin.
3). The wheel is equipped with two sets of main propulsion systems, which are composed of four parts: main engine - gear box - intermediate shaft - stern shaft - propeller; the main engine and gear box are elastically connected, and the gear box and intermediate shaft It adopts steel flange connection, while the stern shaft and intermediate shaft are connected by hydraulic sleeve; the propeller is an adjustable pitch propeller, and the adjustment range of the pitch has been marked on the piston drive shaft (-60mm-- 100mm). Stern bearing To oil lubricate the babbitt material, the front and rear stern bearing sinks are permanently marked near the bearings.
4). Whole-ship bilge water system
The whole ship is equipped with three bilge water pumps of model ESCE-150MD18.5x2 with a displacement of 120 m3/h, which are respectively installed in the engine room and bow. The pump room shall meet the requirements for the special arrangement of bilge water pumps and bilge water pipes in the rules and regulations (SOLAS Convention II-1, Article 21, Paragraph 2.4). There is also a bilge ballast general pump with self-priming capability (model ESCE-250ME-C45, 300m3/h), which can also be used for the bilge drainage system. The fifth deck workroom is equipped with valve remote control operating systems for bilge and ballast systems and tank liquid level remote sensing systems.
5). Fire protection system
There are three fire pumps in the fire protection system of the whole ship. Among them, No. 1 fire pump and No. 2 fire pump are arranged in the engine room, and No. 3 fire pump is installed in the engine room. The fire pump is arranged in the bow pump room, and its arrangement meets the requirements of SOLAS II-2, Article 10, Section 2.2. The ship's water fire-fighting system is divided into two parts: internal and external. The internal piping system is connected to the external piping system through a stop valve. Under normal circumstances, the valve is in a normally closed state. The external fire protection system mainly refers to the open-air part of the piping system, and the internal piping system refers to the water fire protection piping system inside the ship. The internal water fire protection system adopts a constant pressure system composed of a pressure water tank and a constant pressure pump. When the system pressure drops to 0.55MPa, the constant pressure water replenishment pump automatically starts to replenish water to the pressure tank, causing the pressure of the water tank to rise. When the pressure rises to 0.75Mpa, the water supply pump stops working. When the water pressure in the pressure cabinet is lower than 0.5Mpa, the two fire pumps connected to the fire pipes can automatically start to supply water to the fire main pipe. At the same time, the water pressure in the pressure cabinet also rises. When the pressure rises to 0.8Mpa, the fire pump stops working. The No. 2 fire pump and the fire pump arranged in the bow pump room can be started and stopped remotely from the bridge, which can provide fire water to the external water fire fighting system at any time.
The ship is equipped with a fixed CO2 system, and the protected spaces are the engine room, upper vehicle cabin, middle vehicle cabin, bottom vehicle cabin and oil purifier room; the system is equipped with 286 CO2 bottles (68L/bottle) in the CO2 room ). When a fire occurs in the above premises, the CO2 release operation can be completed in the CO2 room and fire control station respectively. In addition, the paint room, crew galley exhaust duct and passenger galley exhaust duct are also equipped with fixed CO2 fire extinguishing systems. 2 CO2 bottles (68L/bottle) used in the paint room are stored in the CO2 room; 1 CO2 bottle (68L/bottle) used in the crew galley exhaust duct is stored in the rear of the fourth deck; used in the passenger galley exhaust duct One CO2 bottle (68L/bottle) is stored in the middle of the fifth deck.
The cabin, living and service areas on the ship are equipped with an automatic water spray system. The system is equipped with a spray fresh water pressure cabinet, a spray constant pressure pump and a cabin spray pump. Powered by two independent sets of power sources. When a protected location occurs
