What are the emergency functions of the ship host remote control system Can

1. In ships equipped with a host remote control system, the host can be operated in three parts: the cockpit, centralized control room and next to the aircraft. In order to ensure that the host can only be operated in one part at the same time, a control part conversion device should be set up.

2. The general classification society requires the host to: low pressure of lubricating oil, high temperature of cooling water, overspeed parking protection and alarm. Generally, there are also speed reduction protection and alarms with security systems: high smoke exhaust temperature, high concentration of crankcase oil mist, low crankcase liquid level, high gearbox oil temperature, low crankcase oil level, and high supercharger temperature.

3. Machine-side emergency operation procedure: The machine-side emergency operation program is mainly used to operate the host next to the machine when the pneumatic remote control system, speed controller or electronic equipment fails. Use the corresponding control mechanism to operate the host to meet the operation under various working conditions.

4. Determine the state of the water at that time (water depth, wind wandering, ship density, barrier-free objects around...) and use the remaining speed to drive the ship to safe waters. ( Prepare double anchors) The driver records the position, speed, hydrological, weather, etc. in time, and informs the captain, informs the captain to determine the cause of the fault and repair it in time.

5. Under normal circumstances, the start & stop requirement of the host is to be able to start and stop on the control panel next to the machine, that is, the mainframe. In addition, the generator screen on the distribution board is also required to be able to start and stop.Emergency stop is the same requirement. In addition, emergency parking is also available in the ESD system.

ship host remote control pneumatic repeat start principle

1. Generally speaking, the remote control host in the centralized control room is realized by using various logic loops and control loops composed of pneumatic valves. It can be fully automatic or semi-automatic, that is, it allows the turbine personnel to gradually reach the operating state required by the vehicle by pulling the control handle.

2. The principle of ship host: 1. Electronically control of diesel engine fuel injection, timing and fuel injection; 2. Traditional diesel engine adopts cam control; 3. Cam rotates to control the opening and closing of the high-pressure oil pump; 4. The electric injection system is composed of sensors, controllers and actuators.

3. The cockpit sends an electrical remote control signal. After being processed by the electric logic loop, it is converted into an air pressure signal by the electric/gas converter and the host is manipulated by the pneumatic logic loop of the centralized control room.

How to adjust the ship host remote control throttle handbrake

Releash the handbrake: Before adjusting the handbrake, you need to release the handbrake. This can be done by gently pulling the handbrake lever or moving your foot off the pedal.

Hand brake adjustment method: If you find that the brake is not sensitive in the test, it can be solved by adjusting the handbrake pull wire. There is an adjustable compensation mechanism under the handbrake handle.

There is an adjustable mechanism at the bottom of the handbrake handle and the copper cable connection (generally covered by internal parts);Use a wrench to loosen the locking nut, so that the length of the brake copper cable can be stretched; however, some car adjustment mechanisms are located on the chassis. If it is inconvenient to adjust, it should be handled by professional maintenance personnel.

Introduction to ship host remote control

Host remote control system is an important part of turbine automation, which is the focus and difficulty of turbine personnel management and use of automation equipment. In the host remote control system, the cockpit remote control host must be fully automatic; the centralized control room remote control host can be fully automatic or semi-automatic.

Overview of the ship's host remote control system. The host's remote control refers to the operation of the ship's diesel engine host through an automatic control device at the cockpit (or centralised control room) next to the machine.Like all control systems, the host remote control system consists of two parts: the controller and the control object (host).

Generally speaking, the remote control host in the centralized control room is realized using various logic loops and control loops composed of pneumatic valves. It can be fully automatic or semi-automatic, that is, it allows the turbine personnel to gradually reach the operating state required by the vehicle by pulling the control handle.

In the year, Fulton of the United States built the first steam engine ship "Clermont" with bright wheel propulsion, with a speed of about 8 km/h; in 1839, the first steam engine ship equipped with a propeller thruster "Archimedes" was launched, with a host power of 58 kilowatts.

This kind of remote control system is usually called an electric-gas combined host remote control system.At present, these two remote control systems are widely used, while the electric-gas combined remote control system is more widely used. The centralized control room adopts a semi-automatic pneumatic remote control system, while the cockpit adopts an electric remote control system.

The principle of remote control pneumatic repeated start-up of the ship host is that the propeller is driven by the propulsion motor, which is a commonly used electric propulsion method. In addition to the power supply engine, the main generator can sometimes supply the ship's power grid.

Microcomputer remote control system of ship host remote control

1. Its centralized control room still adopts a semi-automatic pneumatic remote control system, and the cockpit also sends an electric remote control signal. In fact, it also belongs to the remote control form of the combination of electricity and gas. The difference is that its logic loop is not composed of hardware circuits, but is realized by computer software programs.

2. The cockpit sends a remote control signal of electricity. After being processed by the electric logic loop, it is converted into an air pressure signal by the electric/gas converter and manipulated by the pneumatic logic loop of the centralized control room.

3. Kongsberg, Rolls-Royce, Wartsila. All three brands are world-renowned ship suppliers, with a long history and rich experience. At the same time, they have a leading technology and excellent reputation in the design, manufacture and service of ship host remote control systems.

Introduction to ship host remote control

Host remote control system is an important part of turbine automation and is to realize no One of the prerequisites for unattended machinery space.

Overview of the ship's host remote control system. The host's remote control refers to the operation of the ship's diesel engine host through an automatic control device at the cockpit (or centralised control room) next to the machine. Like all control systems, the host remote control system consists of two parts: the controller and the control object (host).

The speed is about 8 km/h;In 1839, the first steam locomotive ship "Archimedes" equipped with a propeller thruster was launched, with a mainframe power of 58 kilowatts. This kind of thruster fully demonstrates its superiority, so it is rapidly promoted.

Generally speaking, the remote control host in the centralized control room is realized using various logic loops and control loops composed of pneumatic valves. It can be fully automatic or semi-automatic, that is, it allows the turbine personnel to gradually reach the operating state required by the vehicle by pulling the control handle.
