Summary

This lecture explores the fundamentals of electro-hydraulic steering systems used in ships. The speaker covers the main components, including the tele motor (signal transmission), hydraulic pump, and steering gear. The system operates by converting electrical signals into hydraulic actions that control the rudder. The discussion highlights different types of hydraulic pumps, their functioning, and how feedback mechanisms ensure the system returns to a neutral position. The material is designed to offer a detailed understanding of ship steering mechanics, with further exploration of pump types and hydraulic principles in future lectures.

Takeaways

• 😀 Electro-hydraulic steering systems are a combination of electrical and hydraulic technologies used in ship steering installations.
• 😀 The system consists of three main parts: the telemotor (transmitter and receiver), the power unit, and the rudder control mechanism.
• 😀 The telemotor begins at the bridge, where a signal is transmitted to the receiver located in the engine room to control the steering mechanism.
• 😀 The receiver responds to the commands by regulating hydraulic fluid flow, which ultimately moves the rudder.
• 😀 The hydraulic pump, which is powered by an electric motor, plays a critical role in generating the hydraulic power required for steering.
• 😀 The hydraulic pumps used in these systems can be of different types, such as unidirectional, radial, and axial pumps, each serving different purposes depending on the operational conditions.
• 😀 The system's hydraulic pumps can be adjusted using a 'flying road' or 'hunting level' to control the direction and flow of the hydraulic fluid.
• 😀 The direction of hydraulic fluid flow can be controlled using solenoid valves or control valves, depending on the system's configuration.
• 😀 The receiver adjusts the pump position based on commands from the bridge, ensuring that the rudder is set to the correct angle.
• 😀 The overall goal of the electro-hydraulic steering system is to provide precise, reliable control over the ship's rudder through a combination of electrical and hydraulic systems.

Q & A

What is the main focus of the video script?

The main focus of the video script is explaining the basic knowledge of ship steering machine installations, specifically the electro-hydraulic steering systems, their components, and how they work together.

What is the electro-hydraulic steering system composed of?

The electro-hydraulic steering system is composed of three main parts: the telemotor (including the transmitter and receiver), the power unit (which includes the hydraulic pump and actuator), and the rudder assembly.

How does the telemotor work in the system?

The telemotor system starts with a transmitter on the bridge that sends electrical signals to a receiver located in the engine room. The receiver then controls the hydraulic flow to adjust the rudder, based on the signal from the transmitter.

What role do the hydraulic pumps play in the electro-hydraulic system?

The hydraulic pumps generate the hydraulic power needed to drive the rudder. These pumps are driven by electric motors and are responsible for controlling the flow of hydraulic fluid to move the rudder assembly.

What is the significance of using an electric motor in the hydraulic pump?

The use of an electric motor in the hydraulic pump allows the system to be controlled electrically, providing precise control over the hydraulic flow, which in turn governs the movement of the rudder.

What are the two types of hydraulic pumps mentioned in the script?

The two types of hydraulic pumps mentioned are the unidirectional pump and the radial/axial pump. The unidirectional pump only allows fluid flow in one direction, while the radial/axial pump can produce flow in multiple directions depending on its configuration.

How is the hydraulic flow direction controlled in the system?

The direction of the hydraulic flow is controlled by solenoid valves or control valves, which direct the flow of hydraulic fluid to either side of the system, depending on the required movement of the rudder.

What is the function of the 'hunting level' or 'flying road' in the system?

The 'hunting level' or 'flying road' serves as a mechanism to control the position of the hydraulic pump. It helps adjust the hydraulic fluid flow, ensuring that the pump operates in the correct direction based on the signals received from the telemotor system.

How does the system ensure the rudder stays in the correct position?

The system ensures the rudder stays in the correct position by adjusting the hydraulic pump's flow, which is controlled by feedback from the hunting level. Once the desired rudder angle is achieved, the system ensures the pump remains in a neutral position to maintain that angle.

What will be discussed in the second part of the video?

In the second part of the video, the focus will be on the types of hydraulic pumps used in the system and their working principles, along with a more detailed explanation of how these pumps interact with other components of the electro-hydraulic steering system.
